The Boy Who Inspired “The Exorcist”: From Demonic Possession to NASA

The shocking true story of a 13-year-old boy’s demonic possession in 1949 that terrified priests and inspired the most frightening film ever made.

Listen to “The Boy Who Inspired The Exorcist: What Really Happened” on Spreaker.

In January 1949, a 13-year-old boy in suburban Maryland heard scratching sounds coming from inside the walls of his bedroom. His family called an exterminator. The exterminator found no droppings, no nests, no evidence that any animal had ever been there. The scratching continued. Then furniture started moving across rooms with no one touching it. Religious pictures flew off walls. The boy’s mattress shook so violently it moved several feet across the floor while he lay on it. Scratches appeared on his skin forming words, sometimes in places he couldn’t possibly reach himself. When a Catholic priest attempted an exorcism at Georgetown University Hospital, the boy broke free from restraints, tore a metal bedspring from the mattress, and slashed the priest across the shoulder with it.

Over the next three months, between 20 and 30 exorcism sessions were performed on the boy. Forty-eight people witnessed at least part of what happened. Father Raymond Bishop, one of the Jesuit priests involved, kept a meticulous 26-page diary documenting every session. He recorded the boy speaking in voices that didn’t sound human, displaying strength that required multiple grown men to restrain him, and physical marks appearing on his body with no visible cause. The lead exorcist, Father William Bowdern, lost 30 to 40 pounds during the ordeal and developed oozing boils covering his body. Another priest got his nose broken. The sessions continued until Easter Monday, April 18, 1949, when witnesses claim a different voice came from the boy, commanding Satan to leave in the name of St. Michael the Archangel.

The boy’s identity was protected for over 70 years. He grew up to become a NASA engineer who helped develop heat-resistant technology for the Apollo space program. He lived in constant fear that colleagues would discover his secret. He left his house every Halloween, terrified someone would show up at his door. When author William Peter Blatty heard about the case as a Georgetown student in 1949, he couldn’t forget it. Twenty years later, he wrote a novel about it. That novel became The Exorcist, the first horror film ever nominated for Best Picture. The boy died in May 2020. Just before his death, a Catholic priest arrived unbidden at his home to perform last rites. His companion never called for a priest. She has no idea how the priest knew to come.

Hollywood didn’t have to exaggerate this one. The facts are disturbing enough on their own.

The Boy Who Would Become a Legend

Ronald Edwin Hunkeler came into the world on June 1, 1935. His parents, Edwin and Odell Hunkeler, were doing their best to build something stable during America’s recovery from the Great Depression. Edwin kept steady work while Odell managed their home at 3807 40th Avenue in Cottage City, Maryland. The house sat in a quiet corner of suburbia just outside Washington, D.C., where neighbors knew each other and families kept to themselves.

That address matters. Newspapers covering the case years later got it wrong, claiming the family lived in nearby Mount Rainier instead of Cottage City. The mistake had consequences. Teenagers would gather at an empty lot in Mount Rainier, swapping ghost stories and daring each other to stand where the possessed boy supposedly lived. They had no idea they were in the wrong town, scaring themselves over nothing.

Cottage City was the kind of place where everyone recognized everyone else. The Hunkelers fit the pattern – church on Sundays, quiet lives, minimal fuss. Ronald was their only child. Odell’s mother, Anna Coppage, also lived with them. Anna spoke German and had lost her husband about nine years before everything started going wrong. She was a fixture in the household, another constant in Ronald’s daily routine.

School records show Ronald attended Bladensburg Junior High in the fall of 1947. Classmates remembered him, though their memories don’t always line up. Some recalled a quiet kid who liked comic books and radio programs, nothing unusual for the time. Others painted a much darker portrait. One childhood friend, referred to as JC in later interviews, didn’t mince words: Ronald was “never what you would call a normal child” and could be “a mean bastard.” According to JC, Ronald threw tantrums, acted out violently, and even tormented animals and other kids.

JC shared one particularly unsettling memory. There was this nasty dog in the neighborhood that attacked just about everyone. Somehow, Ronald had befriended it. “That dog was really his best friend,” JC remembered. The dog would come into Ronald’s house, following him around like a loyal companion. One day, Ronald called JC over to his house. JC walked up to the door, and that’s when Ronald released the dog to attack him from the back porch. “He’d done this sort of thing many times before to different kids.”

Ronald was either troubled or simply misunderstood. One relationship shaped his childhood more than any other though.

The Spiritualist Aunt

Mathilda Hendricks wasn’t like the rest of the family. Everyone called her Tillie, and she stood out in the conservative Lutheran household. Born in 1895, she’d gotten wrapped up in spiritualism, that movement that swept across America believing you could actually talk to the dead. Spiritualists used mediums, held séances, and relied on tools like the Ouija board to make contact with the other side.

Tillie didn’t see anything wrong with it. To her and others like her, reaching out to deceased loved ones wasn’t dangerous or pagan. Most spiritualists considered themselves perfectly good Christians who just happened to believe the dead could still communicate with the living. The Bible had some warnings about consorting with spirits, sure, but spiritualists didn’t worry too much about that.

Tillie had set up her life in St. Louis, living at 7564 Warner in Richmond Heights. Ronald, being an only child without brothers or sisters to keep him company, spent considerable time with his aunt during family visits. She treated him differently than other adults did – more like a special friend than a nephew. She had this exotic quality about her, especially when she talked about the spirit world and what happened after death.

The Ouija board fascinated Ronald from the moment Tillie introduced him to it. She explained how it worked: the planchette would move across the board, guided by spirits who entered the consciousness of whoever was using it. These spirits created impulses that traveled through the person to the planchette, which then moved to spell out messages or answer yes-or-no questions.

Ronald became hooked. Between visits with Aunt Tillie, he’d pull out the board and use it by himself. This was 1948, remember – before television became standard in American homes, long before video games or the internet. For a 13-year-old kid looking for entertainment, the Ouija board offered hours of mysterious fascination.

Some researchers have suggested darker things might have been happening. There’s evidence that raises questions about whether Ronald was sexually abused by Aunt Tillie or his grandmother, though nothing definitive has been proven. What’s certain is that Ronald spent an enormous amount of time with Tillie, forming a bond that would end up having serious consequences.

Multiple sclerosis was destroying Tillie’s nervous system, progressively attacking the protective covering of nerves and causing neurological problems. On January 26, 1949, at 54 years old, Tillie died. For Ronald, losing her was devastating. She’d been his closest companion, the adult who really understood him, the one person who shared his fascination with mysteries and the unknown.

Ronald grieved hard. In his desperation to keep some connection with the aunt he’d lost, he did exactly what she’d taught him to do. He grabbed the Ouija board and tried to make contact with Tillie’s spirit.

The planchette didn’t move. Something else did.

The Dripping and the Scratching

Saturday evening, January 15, 1949, started out normal enough. Edwin and Odell Hunkeler went out for a bit, leaving Ronald home alone with his grandmother Anna. Not long after his parents left, Ronald and Anna both started hearing this dripping sound. It wasn’t subtle – the noise echoed through the house with this steady, persistent rhythm that immediately got under their skin.

They searched everywhere. Every single faucet was shut tight. No pipes were leaking. They couldn’t find any source for the dripping sound, but it continued. The noise seemed to come from everywhere at once, which made it even more unsettling.

Father Raymond Bishop, who would later document the entire case in careful detail, wrote about what happened that first night. The dripping was just the opening act. A picture of Christ hanging on the wall started shaking for no apparent reason. Then scratching sounds began coming from underneath Grandmother Anna’s bed.

The scratching continued on and off for more than a week. Just when the family thought it might be stopping, the sounds migrated to Ronald’s bedroom. Bishop described the new noise as something like “squeaking shoes” running the length of the bed, over and over again.

The family held onto hope for a rational explanation. Old houses sometimes had animals that got trapped in the walls or under the floorboards. It happened. They called an exterminator.

The exterminator showed up, did his inspection, and heard the scratching sounds himself. He agreed it sounded like an animal had gotten in somewhere. He put down poison under the floorboards and around the house, then waited. When he went back to check beneath the floorboards, he found nothing. No droppings, no nests, no sign that any creature had ever been there. The scratching continued.

For 10 straight days, these mysterious sounds plagued the Hunkeler household. Then things escalated past strange noises.

When Objects Began to Move

Furniture started moving without anyone touching it. Not just sliding a little – a heavy armchair would glide across the floor while everyone watched. Objects flew off shelves. A vase lifted into the air, hung there for a moment, then smashed on the ground. The family stood there watching their possessions develop what looked like minds of their own.

Religious items were affected particularly hard. Pictures of Jesus and the Virgin Mary would fly off walls as if something had punched them from behind. Bottles of holy water would fall and break. The closer Ronald was to a particular room or object, the more likely something weird was going to happen.

Tables flipped over. The floors developed scars from heavy furniture sliding across them. Odell later told investigators that a picture of Christ on the wall would shake whenever Ronald came near it. The phenomena seemed attached to the boy somehow, following him around.

The worst part was what happened to Ronald’s mattress. It started shaking whenever he lay down on it. The bed would rock violently, sometimes moving several feet across the floor. Ronald couldn’t get any sleep. The shaking would wake him up repeatedly throughout the night.

Then Ronald felt something new. These claw-like sensations, scratching under his mattress as if invisible fingers were clawing at the fabric beneath him. His mother and grandmother felt it too when they sat on the bed. There was no mistaking what they were feeling, and it scared the hell out of them.

The disturbances followed Ronald to school. He was sitting in class at Bladensburg Junior High when his desk started shaking violently. His classmate JC never forgot it: “It was one of those deals with one arm attached and it looked like he was shaking the desk. The desk was shaking and vibrating extremely fast and I remember the teacher yelling at him to stop it and I remember he kind of yelled ‘I’m not doing it’ and they took him out of class and that was the last I ever saw of him in school.”

The desk didn’t move around the room like some accounts later claimed – it just shook intensely. JC couldn’t tell if Ronald was causing it or if something else was responsible. The school had seen enough. They pulled Ronald out of Bladensburg Junior High in the middle of his eighth-grade year in January 1949.

Seeking Answers from Science and Faith

Edwin and Odell Hunkeler were running out of options. They took Ronald to medical doctors first. There had to be some physical explanation for his behavior and all the strange stuff happening around him. The doctors did thorough examinations. They found nothing wrong with the boy at all.

Next came psychologists and psychiatrists. Maybe Ronald was mentally disturbed, acting out after losing his aunt. But the mental health professionals couldn’t find any significant psychological conditions either. Whatever was going on with Ronald, conventional medicine had no answers for it.

The physical evidence was getting harder to ignore. Scratches started appearing on Ronald’s body. These weren’t normal scratches from rough play or accidents. They appeared suddenly, sometimes forming patterns. Sometimes forming actual words.

The family reached out to their Lutheran minister, Reverend Luther Miles Schulze. Schulze wasn’t your typical clergyman. He had this deep interest in parapsychology and had spent years studying unexplained phenomena. When the Hunkelers described what was happening, Schulze agreed to observe Ronald himself.

Schulze did something extraordinary. He arranged for Ronald to spend a night at his own home. He wanted to witness the phenomena firsthand, away from the Hunkeler house, to rule out any environmental factors or staging by family members.

That night, Schulze saw things he couldn’t explain. Furniture moved with nobody touching it. Objects fell and broke for no reason. Unexplained sounds filled his house. Schulze later told people he believed the case was genuine and went beyond anything in his spiritual training.

Schulze documented what he saw in a letter to Duke University’s Parapsychology Laboratory, which was run by Dr. J.B. Rhine, a pioneer in studying paranormal phenomena. The letter, dated March 1949, laid out extraordinary claims: “Chairs moved with him and one threw him out [of it]. His bed shook whenever he was in it.”

Schulze described how the family’s floors had become “scarred from the sliding of heavy furniture.” He noted that “a picture of Christ on the wall shook” whenever Ronald was nearby. When Schulze witnessed these events himself, he had no natural explanation to offer.

Dr. Rhine reviewed Schulze’s letter with considerable interest. He later called the case “the most impressive manifestation he has heard of in the poltergeist field.” Rhine did wonder whether Schulze might have “unconsciously exaggerated” some facts, but the basic claims were consistent and witnessed by multiple people.

Schulze made a recommendation that would change the trajectory of the entire case. He suggested the Hunkelers contact a Catholic priest. The Catholic Church maintained ancient rituals for dealing with demonic possession. If something supernatural was happening to Ronald, the Catholics might have answers that Lutherans didn’t.

The Hunkelers were Lutheran, not Catholic. But they were desperate and willing to try anything. They agreed to seek help from the Jesuits.

Father Hughes and the Failed Georgetown Exorcism

The Hunkelers got in touch with Father Edward Albert Hughes, who served as assistant pastor at St. James Church in Mount Rainier, Maryland. Father Hughes was curious about the case but approached it carefully. He met with Odell and Ronald for an initial consultation at the church.

After hearing their story and watching Ronald’s behavior, Hughes became convinced something genuinely abnormal was happening. He contacted his superiors and requested permission to perform an exorcism. The church gave him the green light.

On Monday, February 28, 1949, Ronald was admitted to Georgetown University Hospital under his real name. For three days – February 28 through March 3 – doctors and psychologists put Ronald through extensive physical and psychological testing. The results showed Ronald wasn’t suffering from any significant physical or psychological conditions. Whatever was affecting him, medical science couldn’t diagnose it.

Father Hughes attempted an exorcism at the hospital. He strapped Ronald to a mattress and began reciting prayers from the Roman Ritual. The ancient rite was designed to command demons to leave in the name of God and Jesus Christ.

Ronald’s reaction was immediate and violent. He struggled against the restraints with shocking strength. His body twisted in ways that seemed to go beyond normal physiology. He spit at Father Hughes and spoke in this strange voice that didn’t sound like any 13-year-old boy.

Then Ronald did something that ended the exorcism immediately. He managed to work one hand free from the restraints. In this flash of movement, he broke off a jagged piece of the metal bedspring from under the mattress. He used it as a weapon, slashing Father Hughes across the shoulder. Blood started flowing from the wound. The exorcism stopped immediately.

Father Hughes never tried another exorcism on Ronald. The experience had shaken him profoundly. Years later, he told friends that the boy had lived in Cottage City and had gone on to graduate from Gonzaga High School and “turned out fine.” But Hughes never spoke publicly about the details of what he witnessed that day.

After the failed exorcism, Ronald was released from Georgetown University Hospital on March 3, 1949, at noon. He went home, but the phenomena continued and got worse.

The Message in the Flesh

New scratches continued appearing on Ronald’s body with disturbing frequency. These weren’t random marks anymore. They were forming distinct shapes and, most remarkably, actual words.

One day, Odell pulled back her son’s shirt and gasped. Scratched into the skin on Ronald’s chest was a single word: “HELLO.” The letters were clear and unmistakable. They hadn’t been there moments before.

More words appeared over the following days. The word “HELL” materialized on Ronald’s chest “in such a way that R could look down upon his chest and read the letters plainly,” according to Father Bishop’s diary. On another occasion, what witnesses described as “a picture of the devil” appeared on Ronald’s leg in raised welts and scratches.

Then came the message that would determine what happened next. Scratches appeared on Ronald’s ribcage, forming the word “LOUIS.” The marks rose under his skin over his ribs, clearly visible to his parents and grandmother.

Odell stared at those scratches. “Louis” meant St. Louis, Missouri – her hometown. Her brother Leonard and his wife Doris Hunkeler lived there at 8435 Roanoke Drive in Bel-Nor, a suburb of St. Louis. More relatives, including their cousins Neil and Janis, also lived in the area.

The family took this as a sign. Whatever force was affecting Ronald wanted them to go to St. Louis. Maybe Aunt Tillie’s spirit was trying to guide them back to her hometown. Maybe getting Ronald away from Maryland would help him escape whatever was haunting him there.

Other scratched messages reinforced this interpretation. The word “SATURDAY” appeared on Ronald’s hip. The phrase “3 ½ weeks” showed up on his body, suggesting how long they should stay in St. Louis.

Father Bishop would later write in his diary: “It seems that whatever force was writing the words was in favor of making the trip to St Louis.”

The Hunkelers made their decision. In early March 1949, Odell and Ronald traveled to St. Louis to stay with their relatives. Edwin would join them later. They hoped the move would bring relief to their son and give the family some peace.

They had absolutely no idea that St. Louis would become the site of one of the most documented and controversial exorcisms in American history.

The St. Louis Relatives Witness the Impossible

Ronald and his mother arrived in St. Louis and moved into Leonard and Doris Hunkeler’s home on Roanoke Drive. The house looked like something out of a magazine – beautiful Colonial-style structure with red brick exterior, white shutters, neatly manicured bushes, and tall trees providing shade over the yard. From the outside, it could have been any other comfortable middle-class home in the neighborhood.

Inside, the nightmare continued.

On Monday, March 7, 1949, five or six relatives gathered in the home. They decided to try communicating with whatever spirit might be affecting Ronald. They used an alphabetical medium on a porcelain kitchen table. Letters of the alphabet were written on paper and arranged on the table. The table would move to underline particular letters, spelling out messages.

According to the account Father Bishop documented in his diary, the phenomena indicated the spirit wasn’t the devil but rather the soul of their deceased aunt. When they asked, “If you are Tillie, knock three times,” three distinct knocks were heard on the floor. When they requested confirmation with four knocks, four knocks responded. The knocks were followed by claw-like scratching sounds on Ronald’s mattress.

The spirit’s identity remained murky though. At various times during the ordeal, Odell received what seemed like affirmative answers when she asked if Aunt Tillie was behind the disturbances. Yet something malicious seemed to be building beneath these communications.

Different family members witnessed various phenomena. Two aunts, four uncles, and four cousins all saw furniture get knocked over, Ronald’s mattress swaying violently, and scratching on the mattress. Multiple people watched as the words “No School” appeared on Ronald’s body. The violent bed shaking and scratching on the boy’s skin was witnessed by Odell, an aunt, an uncle, a college-age cousin, and a friend of the family.

When Ronald went to bed that night, violent shaking began. The scratching on the mattress continued. He barely got any sleep.

Tuesday, March 8, the phenomena continued. The bed shook. Objects moved. Scratches appeared on Ronald’s body, each one making him cry out and double over in pain.

On Wednesday, March 9, 1949, Janis Hunkeler, Ronald’s cousin who attended Saint Louis University, was at her wit’s end. She went to one of her professors, Father Raymond J. Bishop, and asked if he could help.

Father Bishop Enters the Case

Father Raymond J. Bishop was 43 years old in 1949. He taught in the education department at Saint Louis University and was known as a dedicated Jesuit priest and scholar. When his student Janis Hunkeler approached him with this extraordinary story, Bishop was skeptical but compassionate. He agreed to visit the family.

Before entering the house that evening, Bishop blessed the entire place with holy water. He wanted to make sure he was spiritually protected before encountering whatever might be inside.

When Bishop walked into Ronald’s bedroom, he found a scene that challenged everything in his rational, educated worldview. Ronald was lying perfectly still on the bed. The bed itself was rattling violently, shaking so hard it looked like it might break apart.

Bishop sprinkled St. Ignatius Holy Water on the bed in the form of a cross. The movement stopped abruptly. For a moment, silence. Then Ronald cried out in sharp pain. Odell quickly pulled back the bed covers and lifted her son’s pajama top. Bold red zigzag scratches had appeared across his stomach in the few seconds since Bishop had sprinkled the holy water.

Bishop was stunned. He’d watched the scratches appear with his own eyes. There was no way Ronald could have done this to himself, not in the position he was lying in, not in those few seconds between the bed stopping and his cry of pain.

Bishop consulted with his colleagues. He spoke with Father Laurence Kenny and Father Paul Reinert, who was president of Saint Louis University at the time. They agreed Bishop should visit the family again and bring backup.

Bishop immediately thought of his friend William S. Bowdern, the pastor of St. Francis Xavier College Church. If anyone could handle something this intense, it was Bowdern.

Father Bowdern: The Combat Veteran Priest

William S. Bowdern was 52 years old in 1949. Born on February 13, 1897, he’d lived through both World Wars and had served as a chaplain in World War II. He’d seen horrors on the battlefield that would have broken most people. He was described as a religious man who was very tough – this combination of deep faith and combat-hardened resilience.

Bowdern had extensive teaching and pastoral experience. The Jesuit community respected him for his wisdom, his strength of character, and his unwavering faith. But like Father Hughes before him, Bowdern didn’t know much about exorcism. It wasn’t something modern priests ran into very often. The Rite of Exorcism was this ancient ritual that had mostly fallen out of use in the 20th century.

On Friday, March 11, Bishop and Bowdern visited the Hunkeler home together. Bowdern wanted to observe the phenomena himself before making any recommendations. Over the next few days, they witnessed furniture moving for no reason, heard scratching noises in Ronald’s bedroom, and saw long scratches in the shape of crosses appear on the boy’s body.

Bowdern was a practical man, slow to jump to supernatural conclusions without compelling evidence. But what he witnessed convinced him that something extraordinary was happening to Ronald. The phenomena couldn’t be explained by trickery or mental illness. The boy needed help that went beyond what doctors could provide.

Bowdern consulted with Father Reinert and with Archbishop Joseph Ritter of St. Louis. On March 16, 1949, Archbishop Ritter granted Bowdern permission to perform a formal exorcism according to the Roman Ritual.

Bowdern immediately started studying. “The first thing he did was hit the books,” as one colleague later recalled. The Roman Ritual provided detailed instructions for the Rite of Exorcism, dating back to 1614. Bowdern studied the prayers, the required preparations, and the various stages of the ritual. He was going to follow the procedures exactly as the Church prescribed.

He recruited several other Jesuits to assist him in what would become a grueling battle lasting over a month.

Assembling the Exorcism Team

Bowdern asked Walter Halloran to help with the case. Halloran was a 26-year-old Jesuit scholastic studying history at Saint Louis University. He also worked as Bowdern’s driver.

One evening, Bowdern asked Halloran to drive him and Father Bishop to a house in the northwest suburbs. Halloran figured he’d wait in the car while the priests went inside. When they pulled up to the house on Roanoke Drive though, Bowdern leaned over to the front seat and said calmly, “Come on in with us, Walt. I’ll be doing an exorcism. We might need your help.”

Halloran was shocked. He’d never witnessed an exorcism. He had no training for this. But he didn’t ask questions. He just followed Bishop and Bowdern into that house, having no idea what he was about to experience.

Other Jesuits joined the effort over the following weeks. Father William Van Roo assisted with many sessions. Father John O’Flaherty participated in some rituals. Father Joseph Boland lent his support. Father Albert Schell and Brother George Bischofberger were also present at various times.

According to newspaper reports, 48 people total would witness the exorcism over its duration. Nine of them were Jesuits. The rest were family members, hospital staff, and other witnesses who happened to be there during the most intense episodes.

Father Bishop took on the crucial role of documenting everything. From the first session on March 16, 1949, through the final confrontation on April 18, Bishop kept this meticulous diary. He recorded dates, times, who was present, Ronald’s reactions, physical phenomena, and every detail he could observe. His diary eventually ran to 26 pages, single-spaced typescript. Six copies were made, though the full unredacted version has never been released to the public.

Bishop’s diary became the primary source for understanding what really happened during those terrifying weeks. It would also end up inspiring a Georgetown University student named William Peter Blatty to write a novel that would terrify the entire world.

The Exorcism Begins

Wednesday, March 16, 1949, marked the beginning of the formal exorcism. Father Bowdern, Father Bishop, and Mr. Walter Halloran arrived at the Hunkeler home on Roanoke Drive between 10:15 and 10:30 PM.

Shortly after 10:30, Ronald was sent to bed. Father Bowdern helped him examine his conscience and make an act of contrition, confessing any sins. Then Bishop, Halloran, Odell, Leonard, and Doris were called into the bedroom to prepare for the exorcism ritual.

Everyone present knelt beside Ronald’s bed. They recited acts of Faith, Hope, Love, and Contrition together. Ronald said the prayers too. Then Father Bowdern, wearing a surplice and stole, began the prayers of exorcism according to the Roman Ritual. Ronald was awake and the overhead light in the bedroom burned brightly.

The prayers were in Latin, the ancient language of the Church. They commanded any demon or evil spirit to identify itself and get out of Ronald’s body in the name of Jesus Christ. They called upon the power of God, the Virgin Mary, and the saints to drive out any malevolent presence.

Ronald’s reaction was immediate and violent. Within the first hour, more than 25 separate markings appeared on his body. Each one caused him to double over in pain, crying out as if something was burning or cutting him. The witnesses watched the marks form on his skin with no visible cause.

When they asked how many demons possessed him, a single line was scratched on Ronald’s right leg. At least four heavy brand marks formed in the shape of an “X.” The priests weren’t sure what these marks meant. Maybe the exorcism would take ten days. Maybe the devil would leave at 10 o’clock. The meaning wasn’t clear.

The markings on Ronald’s legs looked like long scratches with no special meaning at first. As the night went on though, words and symbols began to form.

When the priests recited the Prayer to St. Michael the Archangel, Ronald’s behavior changed dramatically. He started sparring, striking the board back of his bed with strong blows of his fist. Then he began punching the pillow with more than ordinary force, as if fighting an invisible opponent.

The session continued through the night. The priests took turns reciting prayers to avoid exhaustion. They prayed for hours, commanding the demon to identify itself, to reveal how many demons were present, to state their purpose, and ultimately to leave Ronald’s body.

This was only the first night. The battle had barely begun.

Days and Nights of Horror

The exorcism sessions continued nightly throughout the rest of March and into April. Each session brought new and disturbing phenomena. Bishop documented everything in his diary, creating this day-by-day chronicle of escalating terror.

During the day, Ronald was calm and perfectly normal. He’d play, read comic books, and act like any other teenager. But at night, when the priests arrived to perform the exorcism ritual, Ronald would enter this trance-like state. His entire demeanor would shift.

His voice changed, becoming deep and guttural. He spoke words no 13-year-old should know – obscene and blasphemous remarks directed at the priests. He hurled profanity and mockery at anything sacred. When shown crosses or holy relics, he’d recoil as if they were causing him physical pain.

On March 18, 1949, Bishop recorded one of the most violent sessions: “The prayers of the exorcism were continued and R was seized violently so he began to struggle with his pillow and the bed clothing. The arms, legs, and head of R had to be held by three men. The contortions revealed physical strength beyond natural power. R spit at the faces of those who held him and at those who prayed over him.”

Ronald writhed under the sprinkling of holy water. He fought and screamed in this diabolical, high-pitched voice. His physical strength seemed impossible for a boy his size. It took multiple grown men to hold him down.

During the Litany of the Saints portion of the ritual, the mattress would start shaking. Father Bowdern would bless the bed with holy water and the shaking would stop temporarily. Then Ronald’s body would convulse again, requiring the men to hold him down with all their strength.

The priests witnessed phenomena that defied any explanation they could think of. A second-class relic of St. Margaret Mary got thrown to the floor during one session. The safety pin holding it was opened, yet no human hand had touched it.

On another occasion, a bottle of holy water flew across the room, though nobody was anywhere near it. Objects in Ronald’s vicinity seemed to move on their own, flying through the air or falling from surfaces without anyone touching them.

The scratches and markings on Ronald’s body multiplied. The word “HELL” appeared on his chest repeatedly. Other words and symbols formed in welts and scratches. Sometimes the marks appeared on Ronald’s back, in places he couldn’t possibly reach himself.

Bishop wrote in his diary: “The markings could not have been done by the boy for the added reason that on one occasion there was writing on his back.” The priests were certain Ronald wasn’t creating these marks through any kind of trickery.

Each marking caused Ronald intense pain. He’d cry out, his body twisting as if something was cutting or burning him from within. During some sessions, witnesses counted more than 25 distinct marks appearing in a single night.

The Toll on the Exorcists

The exorcism took a severe physical toll on everyone involved, especially Father Bowdern. As the lead exorcist, he carried the primary responsibility. He fasted throughout the entire ordeal, refusing to eat normally while battling for Ronald’s soul.

Betty LaBarge, a relative of Bowdern who had him over for dinner late in the exorcism, was shocked by what she saw. “He must have lost thirty to forty pounds,” she recalled years later. “He looked terrible, just fatigued. When we asked him what was wrong, he simply turned the conversation. It wasn’t until years later we learned he played the leading role in the exorcism. Still he never did talk about it. The word came from others involved.”

The physical stress manifested in other ways. Bowdern’s body became covered with oozing boils – painful lesions that appeared during the weeks of grueling exorcism sessions. Yet he kept kneeling by Ronald’s hospital bed night after night, reciting the prayers of exorcism without any regard for his own health.

At one point during a particularly violent session, Bowdern was kneeling next to the bed, weak and frail, his body covered in boils, but still praying for the boy. A witness to this moment later wrote: “It is this moment when I understood the impact of what was happening to this child and it is because of this moment that I dedicated my book to Roland Doe.”

The other priests and assistants also suffered. During one session, Ronald’s thrashing became so violent that he managed to break Walter Halloran’s nose. Halloran was a young man in excellent physical condition from his time as an athlete, and he was stunned by the strength Ronald displayed.

The priests dealt with lasting effects from the exorcism. Evidence suggests Father Bowdern suffered physical and maybe psychological consequences for the rest of his life. He never fully recovered the weight he lost. Friends noticed a change in him after the exorcism, though he refused to discuss what he’d witnessed.

The Search for Different Locations

The family tried moving Ronald to different locations, hoping a change of venue might help break whatever was happening. In late March, they took Ronald back to Maryland for a few days. Maybe returning home would snap him out of it.

The trip accomplished nothing. On the train ride to Washington, Ronald was calm during the day. But when he went to bed at 11:30 PM, one short spell of violence occurred. The next morning, he woke up normally and was taken to his home in Cottage City without any problems.

Father Bowdern met with Father Hughes in Maryland to coordinate efforts. Hughes had made arrangements with the Chancellor of the Archdiocese of Washington so that Bowdern would have full permission to continue the exorcism in Maryland if necessary. But neither the pastor nor the assistant at St. James Church – the parish Ronald belonged to – could take on full responsibility for the case. There wasn’t enough room, and they didn’t have the resources.

The decision was made that Ronald shouldn’t stay at home. The family and priests agreed to return to St. Louis and continue the exorcism there. They hoped the concentrated efforts of the Jesuit community at Saint Louis University might make a difference.

Back in St. Louis, they tried conducting sessions at the Hunkeler home on Roanoke Drive. But the manifestations were becoming too violent and starting to disturb the neighbors. They needed a more secure location where Ronald could be monitored constantly and where the priests could work without interruption.

The decision was made to admit Ronald to Alexian Brothers Hospital in South St. Louis. The hospital had a psychiatric wing that could provide both medical supervision and the security necessary for these increasingly intense exorcism sessions.

Ronald was admitted to Alexian Brothers Hospital in mid-April 1949. The exorcism moved to a room in the psychiatric wing. The hospital staff got briefed on the extraordinary nature of the case. Many brothers and staff members would witness phenomena they never forgot.

The Final Days at Alexian Brothers Hospital

By mid-April, the exorcism had been going on for over a month. Father Bowdern and his team had conducted somewhere between 20 and 30 separate exorcism sessions. Each one lasted hours, sometimes continuing through the entire night. The priests were exhausted. Ronald was worn down physically and emotionally. The family was desperate for this nightmare to end.

April 18, 1949, was Easter Monday. Archbishop Ritter and the priests believed the timing was significant. Easter represented Christ’s victory over death and Satan. If Ronald was going to be freed, Easter week would be the most powerful time to make it happen.

That morning, Ronald woke up in a violent fit. He thrashed in the hospital bed so hard it took multiple men to hold him down. Father Bowdern continued the rite of exorcism, placing holy items in Ronald’s hands and around his neck.

According to Bishop’s diary, Bowdern then demanded to know the name of the demon possessing Ronald. He commanded the demon to leave the boy in peace, to release its hold and get out immediately in the name of Jesus Christ.

The fit continued with increasing intensity. Then, according to Bishop’s account, the demon spoke through Ronald, mocking the priest. The voice said: “He has to say one more word, one little word, I mean one BIG word. He’ll never say it. I am always in him. I may not have much power always, but I am in him. He will never say that word.”

The priests understood what that meant. There was one more prayer, one more invocation that needed to be said for the exorcism to work. But the demon was confident the priests wouldn’t figure it out or wouldn’t be able to make Ronald say it.

Bowdern and the assisting priests kept going. They continued praying, invoking every saint, calling upon the Virgin Mary, commanding the demon by the power of Christ’s sacrifice. The room felt heavy with spiritual warfare. Witnesses later described feeling this oppressive presence, as if evil itself had become something they could almost touch.

It took five men to hold Ronald down as his body convulsed and contorted. His strength remained superhuman. The priests rotated in and out, taking turns reading the prayers to avoid total exhaustion.

Around 10:45 PM, after hours of this intense spiritual battle, something changed. Ronald became completely still. The violence stopped abruptly. For a moment, there was total silence in the room.

Then a different male voice came from Ronald. It was clear and booming, nothing like the boy’s normal voice or the guttural demonic voice they’d been hearing. This voice sounded authoritative and powerful.

The voice shouted: “Satan! Satan! I am St. Michael, and I command you Satan, and the other evil spirits to leave the body in the name of God, immediately. Now! NOW! N-O-W!”

The witnesses stood there frozen, watching this impossible scene unfold in front of them. Father Bowdern kept praying, amplifying the command. The priests invoked St. Michael the Archangel, the warrior saint who battles demons in Heaven and on Earth.

Seven minutes after the voice of St. Michael spoke through Ronald, the boy woke up. He looked around the room, confused. Then he smiled. He told the priests and his mother something simple: “He’s gone.”

The Aftermath and Recovery

Father Bishop wrote in his diary: “Since Monday at 11 p.m. there have been no indications of the presence of the devil.”

The exorcism was over. Ronald had been freed from whatever had been possessing him. The violent episodes stopped. The scratches stopped appearing on his body. The furniture stopped moving. The strange noises ended. After more than three months of absolute torment, Ronald and his family finally had peace.

Ronald left St. Louis several days later and returned with his parents to Cottage City. He was re-enrolled in the eighth grade at Bladensburg Junior High for the 1949-50 school year, completing the education that had been interrupted back in January.

Three years after everything happened, priests visited Ronald to check on how he was doing. They reported him as “a fine young man.” According to these follow-up visits, Ronald’s parents converted to Catholicism shortly after the exorcism, grateful for what the Catholic priests had done to save their son.

The Catholic Church kept close tabs on Ronald in the years following the exorcism. Church officials wanted to make sure the boy stayed healthy and that no signs of possession came back. The Jesuits who knew the priests involved in the case were sworn to secrecy about Ronald’s identity. They agreed never to publicly reveal his name, respecting his right to privacy and a normal life.

Ronald claimed he remembered nothing of the possession or the exorcism. When asked years later, he told friends he had no memory of the events from January through April 1949. Whether this was actually true or whether he simply chose not to discuss the trauma, nobody knows for certain.

A New Life and Education

In the fall of 1950, Ronald started attending Gonzaga College High School in Washington, D.C. Gonzaga was a prestigious Jesuit preparatory school founded in 1821. He studied there from 1950 through June 1954, graduating as part of the class of 1954.

A yearbook photo from Gonzaga shows Ronald in his senior year. He looks like any other teenage boy from the 1950s – neatly combed hair, serious expression, nothing unusual. In the yearbook, his address is listed as 3807 40th Avenue, Cottage City, Maryland – the correct address that would later help investigators confirm his identity. His church is listed as St. James in Mount Rainier, the parish where Father Hughes had served.

The yearbook photo would turn out to be crucial decades later. Investigator Mark Opsasnick used the 1954 Gonzaga yearbook to identify Ronald. Opsasnick looked for graduates who were members of St. James Church and lived in either Mount Rainier or Cottage City. He found only five students who fit those criteria. Checking Maryland birth records, Opsasnick narrowed it down to one student born on June 1, 1935: Ronald Edwin Hunkeler.

After graduating from Gonzaga, Ronald pursued higher education. He earned a degree in Chemical Engineering, showing real aptitude for science and mathematics. He then went after a second degree in Psychology – maybe drawn to understand the human mind after his own extraordinary experiences.

Ronald got married in 1970, around age 35. He and his wife had three children together: two sons and a daughter. According to some sources, he reportedly named his first son Michael, after St. Michael the Archangel who had appeared during the final exorcism and commanded the demon to leave. Whether this naming choice was coincidental or intentional, it represented some kind of connection to the supernatural events of his youth.

The NASA Engineer Who Helped Reach the Moon

Ronald joined NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The Goddard Space Flight Center – named after American rocket propulsion pioneer Robert H. Goddard – was one of NASA’s major laboratories. It focused on developing and operating unmanned scientific spacecraft and managing spaceflight operations.

A July 27, 1964 article appeared in NASA’s Goddard Space Center newsletter profiling “Ronnie.” The article highlighted his engineering work, though it made absolutely no mention of his past. His colleagues knew him as this dedicated, brilliant engineer with a real knack for solving complex technical problems.

Ronald’s most significant contribution to the space program involved developing specialized technology for spacecraft heat resistance. Space shuttles and capsules face extreme temperatures during launch and especially during reentry into Earth’s atmosphere. The friction between the spacecraft and atmosphere generates temperatures hot enough to melt most materials.

Ronald patented special technology to make space shuttle panels resistant to extreme heat. His innovation involved developing materials and systems that could withstand the intense thermal stress of space travel. This technology proved crucial for the Apollo missions of the 1960s.

The Apollo program, which successfully put American astronauts on the moon in 1969, relied on numerous technological innovations. Ronald’s heat-resistant panel technology was one of many critical components that made the moon landings possible. Without advancements like his, the astronauts aboard Apollo 11 couldn’t have safely traveled to the moon and back to Earth.

Ronald worked at NASA for nearly 40 years, from around 1961 to 2001. He retired from the space agency in 2001 at age 66. His career represented a remarkable achievement, especially given the trauma he’d experienced as a teenager.

Throughout his entire adult life though, Ronald lived with a secret. He carried this burden of knowing he was the real-life inspiration for one of the most terrifying films ever made.

Living with a Terrifying Secret

Very few people knew Ronald’s true identity during his lifetime. A handful of close friends knew his story. The Jesuits who had participated in or knew about the exorcism kept their promise of silence. A few academics and reporters who investigated the case figured out his identity but chose not to reveal it publicly out of respect for his privacy.

Ronald worked alongside dozens, maybe hundreds, of colleagues at NASA Goddard Space Flight Center over the years. None of them knew that the quiet engineer in their department was “Roland Doe,” the boy whose possession inspired The Exorcist.

A woman who was Ronald’s companion for 29 years before his death told The New York Post that Ronald lived in constant fear. “He was always on edge about his colleagues at the NASA Goddard Space Flight Center finding out that he was the inspiration for The Exorcist,” she said.

The fear wasn’t just about professional embarrassment. Ronald worried that if people discovered the truth, his entire life would be destroyed. He imagined reporters camping outside his home. He feared his family would be harassed constantly. He worried that his children would be targeted or bullied because of their father’s infamous past.

Halloween was particularly rough for Ronald. Every October 31st, as children dressed as monsters and demons knocked on doors throughout America, Ronald and his companion would leave their home. They wouldn’t come back until late at night, after trick-or-treating had ended.

“On Halloween, we always left the house because he figured someone would come to his residence and know where he lived and never let him have peace,” his companion recalled. “He had a terrible life from worry, worry, worry.”

The companion revealed something even more surprising though. Ronald insisted throughout his life that he’d never been possessed. “He said he wasn’t possessed, it was all concocted,” she told the Post. “He said, ‘I was just a bad boy.'”

This claim raises some profound questions. Was Ronald truly possessed by demons as the priests believed? Or was he a troubled, attention-seeking teenager who manipulated religious adults? Did he remember nothing of the events, or did he remember everything and just chose to reinterpret it as an act?

Some investigators believe Ronald was simply “a deeply disturbed boy, nothing supernatural about him.” Author Mark Opsasnick proposed that “Roland Doe” was just a spoiled, disturbed bully who threw deliberate tantrums to get attention or to avoid school.

Classmates who knew Ronald as a child backed up this interpretation. They described him as mean, prone to tantrums, violent toward animals and other children. JC, his childhood friend, put it bluntly: “People ask what he was like back then and I can tell you that he was never what you would call a normal child. He was an only child and kind of spoiled and he was a mean bastard.”

Yet these psychological explanations have a hard time accounting for some of the documented phenomena. Multiple witnesses saw objects move with nobody touching them. Respected religious leaders like Reverend Schulze, who’d spent years studying parapsychology, witnessed events they couldn’t explain. Dr. J.B. Rhine called it “the most impressive manifestation he has heard of in the poltergeist field.”

The scratches that appeared on Ronald’s back, in places he couldn’t reach, remain unexplained. The superhuman strength he displayed when multiple grown men were holding him down seems beyond normal adolescent capability. The distinctive voice that witnesses heard coming from Ronald didn’t match his normal speaking voice.

Father Walter Halloran, who was there during many exorcism sessions, offered a more measured perspective in later interviews. He acknowledged he never heard Ronald’s voice truly change in the dramatic way shown in the movie. Halloran thought Ronald might have just mimicked Latin words he heard the priests say rather than suddenly gaining fluency in a language he’d never studied. He noted that poltergeist phenomena could potentially be explained by trickery or unconscious psychokinesis.

Yet Halloran also said something significant: after the rite was over, the anonymous subject of the exorcism went on to lead “a rather ordinary life.” For Halloran, the success of the exorcism – the total cessation of all phenomena and Ronald’s return to normalcy – suggested something real had occurred, even if its exact nature remained a mystery.

The Mysterious Priest Who Arrived Unbidden

Shortly before Ronald’s death in 2020, something happened that his companion couldn’t explain and that Ronald himself found deeply meaningful.

Ronald suffered a stroke at his home in Marriottsville, Maryland. He was 84 years old, just one month shy of his 85th birthday. The stroke was severe. His companion knew the end was approaching.

Suddenly, a Catholic priest appeared at their door. The priest had come to perform last rites – the Catholic Church’s final sacrament for the dying. Last rites involve anointing the dying person with holy oil, hearing their final confession, and offering prayers to prepare their soul for the afterlife.

Ronald’s companion was completely stunned. She hadn’t called for a priest. Neither Ronald nor she had contacted the Church. They weren’t regular attendees at any parish. Most of Ronald’s adult life had been spent keeping distance from the Catholic Church and the memories of his teenage ordeal.

Yet here was a Catholic priest, showing up uninvited at the exact moment Ronald needed him most.

The priest performed the last rites. Ronald, despite his weakening condition, participated in the ritual. Whatever he’d believed throughout his life about his possession – whether it was real or concocted, demonic or psychological – Ronald accepted the priest’s ministry in his final moments.

Ronald’s companion struggled to make sense of this extraordinary coincidence. “I have no idea how the Father knew to come,” she said. “But he got Ron to heaven. Ron’s in heaven and he’s with God now.”

Ronald Edwin Hunkeler died on May 10, 2020, at age 84. His death occurred during the COVID-19 pandemic, when the world was grappling with its own form of invisible threat. The news of his passing didn’t make headlines. Most people had no idea that the real-life inspiration for The Exorcist had just died quietly in Maryland.

For months after his death, Ronald’s identity remained protected. The Jesuits who knew the truth kept their silence. Family members kept the secret. Academics who had identified him years earlier still respected his privacy.

The Identity Revealed

In December 2021, more than 18 months after Ronald’s death, The Skeptical Inquirer published an article that finally revealed the truth to the world.

Investigator and podcast host JD Sword had been researching the case for his podcast, “The Devil in the Details.” Sword confirmed Ronald’s identity through multiple sources and pieces of evidence. He interviewed Mark Opsasnick, who had identified Ronald back in 1999 but chose not to publish the name. Sword got confirmation from T. Weston Scott Jr., a Cottage City resident since 1919 who had known the Hunkeler family. Scott confirmed: “The boy involved was [Ronald Edwin Hunkeler] and he lived at 3807 40th Avenue.”

Sword found the 1954 Gonzaga yearbook photo showing Ronald. He confirmed through Ancestry.com that Ronald’s parents were Edwin Hunkeler and Odell Coppage. He verified that Edwin had a sister named Mathilda Hendricks – Aunt Tillie. He confirmed Ronald was born June 1, 1935, and died May 10, 2020.

When Sword asked Opsasnick directly if he could now confirm Ronald Hunkeler was Roland Doe, Opsasnick replied simply: “The Haunted Boy is Ronald Hunkeler. That’s a fact.”

The revelation made news worldwide. The New York Post, The Guardian, Inside Edition, and countless other media outlets ran the story. After 72 years of anonymity, the real name behind “Roland Doe” was finally public knowledge.

The revelation came too late for Ronald to suffer the consequences he’d feared his entire adult life though. He was already gone. His children and family members dealt with the sudden media attention, but Ronald himself was spared the invasion of privacy he’d dreaded for decades.

The Priests Who Kept the Secret

Father William S. Bowdern died on April 25, 1983, at age 85. He never publicly disclosed details of the exorcism. He kept his promise to Archbishop Ritter and to the Hunkeler family. Even on his deathbed, Bowdern maintained his silence about what he’d witnessed in 1949.

To this day, many faithful Catholics wonder why Father Bowdern hasn’t been considered for canonization as a saint. He endured tremendous physical suffering during the exorcism. He risked his health and potentially his life to save a boy’s soul. He displayed extraordinary courage, faith, and dedication. Yet the Church has never moved forward with any official recognition of Bowdern’s sacrifice.

Father Raymond J. Bishop died on February 19, 1978. He’d spent years at Creighton University in Omaha, Nebraska, where he taught for more than 20 years. Like Bowdern, Bishop never spoke publicly about the details of the case. His diary remained hidden away, with only a few copies circulating among Church officials and trusted researchers.

An interesting coincidence happened at Creighton: Bishop taught alongside another Jesuit professor named Eugene Gallagher. This Father Gallagher was beloved for his kindness and for feeding and training campus squirrels. He wasn’t the same Father Eugene Gallagher who taught at Georgetown University and who told William Peter Blatty about the exorcism though. The two men just happened to share the same name.

Father Walter Halloran lived longer than the other main participants. He died at age 83. Unlike Bowdern and Bishop, Halloran did give some interviews about the case in his later years. He appeared in documentaries and spoke with researchers. But he was always careful not to reveal identifying details about Ronald or the family.

Halloran’s accounts provided valuable information while maintaining the family’s privacy. He confirmed the basic facts of the case. He acknowledged witnessing phenomena he couldn’t explain. But he also introduced notes of skepticism, suggesting some aspects might have been exaggerated or misinterpreted.

Father William Van Roo, Father John O’Flaherty, and the other priests involved similarly maintained their silence. They honored their promise to protect the boy’s identity. Most of them died without ever publicly discussing what they witnessed.

The Alexian Brothers Hospital, where the final exorcism took place, no longer exists. The building was later renamed South City Hospital. In 2023, it closed its doors permanently. The psychiatric wing where Ronald spent those final terrifying nights in April 1949 was demolished years ago. The room where St. Michael’s voice supposedly commanded Satan to leave doesn’t exist anymore.

The House on Roanoke Drive

The house at 8435 Roanoke Drive in Bel-Nor, Missouri, still stands today. It’s changed ownership several times since the Hunkelers left in 1949. The current occupants likely know about the house’s infamous history, though whether they experience any paranormal activity remains their private business.

In 2005, the Riverfront Times published this detailed investigation into the case, including the first public revelation of the Roanoke Drive address. Filmmaker Troy Taylor has documented the location extensively. Ghost hunters and paranormal investigators have visited the house, some claiming to detect unusual energy or activity.

The house appeared in a 2010 documentary titled “The Haunted Boy: The Secret Diary of the Exorcist.” The documentary crew visited the location and interviewed people connected to the case. They uncovered Father Bishop’s diary and presented excerpts from it, though the full unredacted version remained protected by the Church.

Season 8, Episode 7 of “Ghost Adventures” investigated the house in 2012. The show’s investigators claimed to experience unexplained phenomena during their visit. Father Bowdern’s actual great-niece, who was interviewed for various documentaries, refused to ever set foot back in the house. She told interviewers she believed a demonic force was still there.

Whether any supernatural presence remains in the house is a matter of faith and interpretation. What’s certain is that the house has become a landmark in American paranormal history, forever tied to one of the most documented cases of alleged demonic possession.

William Peter Blatty and The Exorcist

The events of 1949 might have remained an obscure footnote in Catholic Church history if not for William Peter Blatty. Blatty was a senior at Georgetown University in Washington, D.C. when the case first made news.

In August 1949, The Washington Post published an article with the headline “Priest Frees Mt. Rainier Boy Reported Held In Devil’s Grip.” The article, written by Bill Brinkley, provided anonymous details about a 14-year-old boy who had undergone exorcism. The article mentioned strange noises, moving furniture, and priests battling to free the boy from demonic possession.

Blatty read the article with fascination. What really grabbed his imagination though came from his professor, Father Eugene Gallagher, a Jesuit priest at Georgetown. Gallagher told his class about the case, mentioning that one of the priests involved had kept this detailed diary of the events.

The story stayed with Blatty for two decades. He became a successful screenwriter, working primarily on comedies like “A Shot in the Dark,” a Pink Panther movie. But he couldn’t shake the 1949 exorcism from his head. He knew he had to write about it.

In the late 1960s, while researching for his novel, Blatty contacted Father Bowdern directly. He wanted to hear the story from the exorcist himself. Bowdern was cautious. He’d promised the Archbishop and the family that he would never reveal details of the case. The boy’s identity had to stay protected.

Bowdern couldn’t tell Blatty everything, but he reportedly said: “I can assure you of one thing: The case I was involved with was the real thing.”

Blatty also got access to Father Bishop’s diary, or at least excerpts from it. The diary gave him the foundation for his novel. He changed key details to protect the real people involved and to enhance the dramatic narrative. The possessed boy became a girl named Regan. The setting moved from Maryland and St. Louis to just Washington, D.C. Father Bowdern became Father Lankester Merrin. Father Karras, the doubting younger priest, was a fictional creation.

Blatty’s novel “The Exorcist” was published in 1971. It became a massive bestseller, shooting to the top of charts and grabbing the public’s imagination. People were terrified and fascinated by the idea that demonic possession could happen in modern America, in an ordinary suburban home, to an ordinary child.

Director William Friedkin reached out to Blatty about turning the novel into a film. Blatty wrote the screenplay himself, making sure the adaptation stayed faithful to his vision. The movie premiered in December 1973.

The Cultural Phenomenon

“The Exorcist” terrified audiences in ways no horror film had done before. People fainted in theaters. They threw up in the bathrooms. Some fled the cinema halfway through, unable to handle the intensity. Theaters hired emergency medical personnel to deal with viewers who became physically ill or suffered panic attacks.

The film’s power came from its claim to be based on true events. Opening credits stated the story was inspired by real occurrences. Audiences understood they weren’t watching pure fiction. Something like this had actually happened somewhere. Demons could possess people. Evil was real and could work its way into ordinary homes.

The movie became the first horror film to receive a Best Picture nomination at the Academy Awards. It won two Oscars: Best Adapted Screenplay for Blatty and Best Sound. It got nominated for eight additional Academy Awards, including Best Picture, Best Director for Friedkin, and Best Actress for Ellen Burstyn.

The film’s success sparked this huge cultural phenomenon. Interest in exorcism exploded. Requests for exorcisms increased dramatically in Catholic dioceses around the world. Books about demonic possession became bestsellers. Other horror films tried to copy The Exorcist’s success by claiming to be “based on true events.”

The Catholic Church found itself dealing with renewed attention to exorcism, a ritual many modern Catholics had considered outdated. The Church responded by updating its guidelines. The Rite of Exorcism got revised in 1999, incorporating modern psychological understanding. The new guidelines emphasized that anyone claiming to be possessed must first be thoroughly evaluated by medical doctors to rule out mental or physical illness.

Modern Catholic officials regard genuine demonic possession as extremely rare, easily mistaken for natural mental disturbances. Most reported cases of possession are now recognized as mental illness, trauma responses, or attention-seeking behavior.

The Exorcist made sure the 1949 case would never be forgotten though. Decades later, the film remains culturally relevant. It regularly shows up on lists of the greatest horror films ever made. New generations discover it and get disturbed by its visceral imagery and themes.

The Search for Truth

Was Ronald Hunkeler genuinely possessed by demons? Or was he a troubled teenager acting out? The debate continues among believers, skeptics, and researchers.

Those who believe the possession was real point to multiple witnesses who saw things they couldn’t explain. Reverend Schulze, an educated minister with knowledge of psychology and parapsychology, witnessed events that convinced him something supernatural was going on. Dr. J.B. Rhine, a serious scientist who studied paranormal phenomena, called it the most impressive poltergeist case he’d run across.

The priests who participated in the exorcism believed they were battling genuine evil. Father Bowdern held onto that belief until he died. These weren’t superstitious, uneducated men. They were Jesuit priests with extensive education, including training in philosophy, theology, and often secular subjects like science or literature.

The physical phenomena documented in Father Bishop’s diary are hard to explain through normal means. Objects moved without anyone touching them. Scratches appeared on Ronald’s body in places he couldn’t reach. His physical strength during episodes seemed far beyond what a 13-year-old boy should have. The immediate cessation of all phenomena right after the final exorcism suggests something real had been affecting Ronald.

Skeptics offer different explanations. Ronald was a troubled child from a dysfunctional family. His mother and grandmother were deeply religious and interested in spiritualism, potentially creating this suggestible environment. Ronald may have learned to fake phenomena to get attention or avoid school. His violent behavior and tantrums were consistent with conduct disorder, not demonic possession.

The poltergeist phenomena could have been staged. A determined teenager could move furniture, create noises, and even make scratches on his own body. The “superhuman strength” could be adrenaline-fueled aggression that multiple men had trouble containing. The voices and personality changes could be deliberate acting.

Father Halloran himself introduced doubt in later years. He never heard Ronald speak in languages he didn’t know. The boy seemed to mimic Latin rather than genuinely speak it. Halloran thought the bed moved because it was on rollers, not through supernatural force. He acknowledged the phenomena could potentially be explained naturally, even if he personally couldn’t explain everything he witnessed.

Author Thomas B. Allen, who wrote “Possessed: The True Story of an Exorcism,” concluded that “Robbie was just a deeply disturbed boy, nothing supernatural about him.” Allen’s book presented “the consensus of today’s experts” that the case was psychological, not demonic.

Yet some aspects of the case resist easy explanation. How did multiple witnesses simultaneously observe objects moving? If Ronald was faking scratches on his back, how did he create them in places he couldn’t reach? Why did all phenomena stop immediately and permanently after the final exorcism if Ronald was just acting?

JD Sword’s investigation for The Skeptical Inquirer concluded: “While we’ll never know all the details or be able to definitively prove that nothing supernatural or diabolical took place in 1949, there is overwhelming evidence to suggest the sensational account of the exorcism of Roland Doe, a.k.a. Ronald Hunkeler, is more fantasy than fact.”

Then there’s that mysterious priest who showed up unbidden to give Ronald last rites in 2020. How did the priest know to come? Why did he appear at that exact moment? Was it coincidence? Divine intervention? Something in Ronald’s own psychology calling out for the ritual that had defined his youth?

Ronald’s companion was certain of one thing: “He got Ron to heaven. Ron’s in heaven and he’s with God now.”

The Legacy

The case of Roland Doe / Ronald Edwin Hunkeler stands as one of the most thoroughly documented alleged cases of demonic possession in American history. Between 20 and 30 exorcism sessions were performed. Forty-eight people witnessed at least some portion of the events. A detailed diary documented daily occurrences. Newspapers reported on the case in 1949. Medical and psychiatric professionals examined the boy.

The case inspired one of the most successful novels and films in history. “The Exorcist” brought discussions of evil, possession, and spiritual warfare into mainstream American culture. It challenged modern secular assumptions about the nature of reality. Could science and reason explain everything? Or were there forces beyond human understanding still working in the world?

The case also shows the tension between faith and skepticism. For believers, Ronald’s case proves that evil exists in supernatural form and that faith and ritual can fight against it. For skeptics, the case demonstrates how religious belief systems can interpret natural phenomena or psychological disturbances as supernatural events.

Both perspectives have to wrestle with uncomfortable facts. Believers need to explain why Ronald himself denied being possessed and why some documented claims seem exaggerated. Skeptics need to explain witnessed phenomena that resist easy natural explanations and why all disturbances stopped after the exorcism.

Maybe the most important legacy is the human story. Ronald Hunkeler lived 85 years. He overcame extraordinary childhood trauma, whether demonic or psychological. He earned multiple college degrees. He contributed significantly to America’s space program and helped put humans on the moon. He got married, raised children, and built a life.

Yet he carried this burden of fear his entire adult life. He worried constantly that people would discover his secret. He couldn’t fully escape the shadow of those terrible months in 1949. Even his denials that he was possessed might have been defensive mechanisms to cope with trauma.

In his final moments, Ronald accepted the ministry of a Catholic priest. Whatever he believed about demons and angels, possession and exorcism, he allowed himself to be connected one last time to the faith tradition that had tried to save him as a child.

The truth of what really happened to Ronald Edwin Hunkeler in 1949 died with him. We’ve got the diary, the witness accounts, the news reports, and decades of investigation. We’ve got competing interpretations from believers and skeptics. We’ve got a Hollywood masterpiece that reimagined the events.

We’ll never know what Ronald truly experienced during those dark months though. We’ll never know if the voice of St. Michael really commanded Satan to leave. We’ll never know if demons are real or if a troubled boy found a way to manipulate the adults around him.

What we do know is that the boy who allegedly harbored demons grew up to become a man who helped humanity reach the stars. Whether the horror he experienced was supernatural or psychological, Ronald survived it and built a remarkable life. That, maybe, is the real miracle of this story.
