The Slender Man Stabber Walked Away — And Nobody Noticed for 12 Hours

The woman who stabbed her classmate nineteen times to please a fictional internet monster has cut off her ankle monitor and fled — triggering a multi-state manhunt that ended at an Illinois truck stop.

Morgan Geyser is a name that still makes people in Wisconsin uncomfortable. She’s the girl who, at twelve years old, stabbed her best friend nineteen times because she believed a fictional internet monster named Slender Man would hurt her family if she didn’t. That was back in 2014. She spent years in a psychiatric hospital, and earlier this year, after a long legal battle, she finally won conditional release to a group home with round-the-clock supervision and a GPS ankle monitor tracking her every move. The system was supposed to keep her — and everyone else — safe.

This weekend, that system failed.

The Night She Disappeared

Saturday night, November 22, 2025, seemed routine at the Madison, Wisconsin group home where Morgan had been living since her release. Nothing appeared out of the ordinary. Then, around 9:30 p.m., the Wisconsin Department of Corrections received an alert that Geyser’s GPS monitoring bracelet was “malfunctioning.”

An alert like that should trigger an immediate response. This is a woman who tried to commit murder as a child. Her whereabouts should matter. But it took two full hours — until 11:30 p.m. — before the department contacted the group home to check on her. And when they finally did make that call, staff at the facility informed them just five minutes later that Geyser was not there and that she had removed her GPS ankle bracelet.

She hadn’t just wandered off. She’d cut the thing off and left.

The timeline from this point is frustrating. The Department of Corrections issued an apprehension request around midnight, but somehow, that request was never relayed to Madison Police. The people who should have been actively searching for her didn’t even know she was gone. It wasn’t until 7:46 a.m. Sunday that someone from the group home finally called 911 to report Geyser as a missing person. That means Madison Police weren’t aware she had disappeared until nearly twelve hours after she’d actually left.

Twelve hours is a long time. It’s enough time to get very, very far away. And that’s exactly what Morgan Geyser did.

The Bus Ride South

By the time anyone started looking for her in earnest, Morgan was already across state lines.

She and her companion had taken a bus from Wisconsin to the Chicago area, then walked to Posen, Illinois — a small community about twenty miles south of Chicago. The distance from Madison to Posen is roughly 170 miles. She’d put an entire state between herself and the group home she’d fled.

The companion traveling with her would turn out to be significant.

Sunday night, around 10:30 p.m., officers with the Posen Police Department were dispatched to a Thornton’s truck stop at 14840 Western Avenue. The call wasn’t about a fugitive or a missing person — someone had reported a man and a woman loitering behind the building. Just two people hanging around where they shouldn’t be.

When officers arrived, they found two individuals sleeping on the sidewalk. A man and a woman, both looking like they’d been traveling and were exhausted. The officers did what officers do — they asked for identification.

The woman wouldn’t give her name. She initially provided officers with a false identity, hoping maybe they’d move on, maybe they wouldn’t dig deeper. But the officers kept asking. They weren’t going to let two people sleep behind a truck stop without at least knowing who they were.

And then Morgan Geyser said something that stopped everyone cold.

After continued attempts to identify her, she finally stated that she didn’t want to tell officers who she was because she had “done something really bad,” and suggested that officers could “just Google” her name, according to the statement later released by the Posen Police Department.

Just Google me. That’s what she said. Because Morgan Geyser knows exactly how notorious she is. She knows that her name brings up headlines about attempted murder, about Slender Man, about a twelve-year-old girl left bleeding in the woods. She didn’t have to explain what she’d done. A simple internet search would tell the whole story.

Once she provided her real name, officers confirmed she was Morgan Geyser, wanted in Wisconsin for escape. The manhunt that had been underway for less than a day was over. She was taken into custody at approximately 10:34 p.m.

The Man Who Snuck Through Her Window

Morgan wasn’t alone when she fled, and the identity of her traveling companion calls into question how closely she was actually being monitored at the group home.

A police report identified the man found with Geyser as 43-year-old Chad Mecca. He’s twenty years older than her, and according to what Morgan told officers after her arrest, their relationship had been ongoing for some time — even though it apparently wasn’t supposed to be.

Geyser told officers she felt she was treated unfairly at the group home and was upset that Chad was not allowed to visit her. The facility had rules about who could come and go, and Mecca wasn’t on the approved list. But that didn’t stop him. She told police that Mecca had snuck in through her window on multiple occasions to see her at the group home.

Multiple occasions. This is a facility that was supposed to be providing 24-hour supervision of a woman who attempted murder as a child. And a 43-year-old man was climbing through her window to visit her without anyone noticing.

When asked about her ankle monitor, Geyser stated she had cut it off with scissors and that she and Chad had discussed potentially making their way to Nashville, Tennessee.

Nashville. Not north toward the Wisconsin wilderness, like she’d tried to go in 2014 when she believed Slender Man’s mansion was waiting for her in the Nicolet National Forest. This time, the destination was real — a city, a place that actually exists on a map. Whether that represents progress in her mental state or just a different kind of escape attempt is hard to say.

They stopped walking after Geyser injured her foot, which is how they ended up sleeping behind that truck stop in the first place. If she hadn’t hurt herself, they might have kept going. They might have made it a lot farther before anyone found them.

Mecca was charged with criminal trespassing and obstructing identification and has since been released. His role in all of this — how he met Morgan, how long they’d been in contact, how he managed to sneak into a supervised facility multiple times — remains unclear.

What She Left Behind

While Morgan was on a bus heading toward Chicago, the people who cared about her were starting to panic.

Geyser’s mother, Angie Geyser, released a statement while her daughter was still missing: “If you see Morgan, please call the police. Morgan, if you can see this, we love you and just want to know you are safe.”

It’s the kind of plea you’d expect from any parent whose child has disappeared. But the context here is complicated. Angie Geyser has stood by her daughter through more than a decade of legal proceedings, psychiatric evaluations, and public scrutiny. She’s watched Morgan transform from a disturbed child into a young woman who seemed to be making progress. And now she was watching that progress unravel in real time.

Morgan’s attorney, Tony Cotton, also went public with a plea before she was captured, posting a video statement to social media urging her to turn herself in. Cotton had spent years fighting for Morgan’s release. He’d argued before judges that she was no longer dangerous, that treatment had worked, that she deserved a chance at something resembling a normal life.

“We worked too hard to secure her freedom for her to continue on this path,” he said.

There’s a particular kind of frustration in that statement. Cotton wasn’t just worried about his client — he was watching years of legal work evaporate. Every argument he’d made about Morgan being ready for supervised release, every psychiatric evaluation he’d cited, every assurance he’d given the court — all of it was being undermined by a pair of scissors and a bus ticket to Illinois.

The Family That Never Stopped Watching

On the other side of this story is another family — one that has spent eleven years trying to move forward while knowing the girl who nearly killed their daughter was still out there.

“Payton and her family are safe and are working closely with local law enforcement to ensure their continued safety,” a statement from the Leutner family said after Morgan’s capture. “The family would like to thank all of the law enforcement entities involved in the efforts to apprehend Morgan.”

Payton Leutner was twelve years old when Morgan stabbed her nineteen times in a Waukesha park in May 2014. She’d thought they were friends. She’d spent the night at Morgan’s house for a sleepover, eaten donuts for breakfast, gotten dressed, and headed out into what she believed was going to be a game of hide-and-seek in the woods. She had no idea her two closest friends had been planning her death for months.

One wound came so close to a major artery that if the knife had gone the width of a human hair deeper, Payton would have bled out in those woods. Instead, somehow, she found the strength to crawl. With nineteen stab wounds, with her attackers walking away believing she was already dead, Payton pulled herself through the underbrush until she reached a bike path. A cyclist found her there, covered in blood, barely conscious.

She survived. She’s now in her early twenties, described by those who know her as excelling in school. But the trauma of that morning — the betrayal by two girls she trusted completely — doesn’t just go away because years have passed.

Earlier this year, when Morgan’s release was being planned, Payton’s mother broke her long silence to object to the proposed placement. The original plan would have put Morgan in a group home in Manitowoc, Wisconsin — just eight miles from where Payton lived. Eight miles. In a car, that’s about ten minutes. On foot, it’s a few hours. For a mother who’d nearly lost her daughter to Morgan’s delusions, that proximity was unbearable. The court listened, and a new placement was arranged farther away.

But “farther away” doesn’t mean safe. This weekend proved that. Morgan’s ankle monitor didn’t stop her. The 24-hour supervision didn’t stop her. The carefully constructed system designed to keep track of her whereabouts failed, and for about twenty-four hours, the Leutner family had to wonder whether the situation they’d been dreading for eleven years was about to get worse.

The Long Road to Release

To understand why Morgan Geyser was living in a Madison group home in the first place, you have to understand the legal battle that’s been going on since she was sentenced.

Morgan pleaded guilty to attempted first-degree intentional homicide in 2017, but she claimed she wasn’t responsible because she was mentally ill. The court agreed. In 2018, Waukesha County Circuit Judge Michael Bohren sentenced her to 40 years in a psychiatric facility — the maximum allowable sentence. She was sent to the Winnebago Mental Health Institute, where she would spend the next seven years of her life.

The system, though, permitted her to petition for conditional release every six months. In 2022, she made her first attempt but withdrew it two months later. Then, in early 2024, a Wisconsin judge scheduled an April hearing to evaluate whether years of treatment had made her fit to reenter society.

The hearing didn’t go smoothly. State health officials raised troubling concerns about Morgan’s behavior inside the facility. She’d been reading a novel about murder and black market organ sales — not exactly the kind of material that inspires confidence in someone’s rehabilitation. Even more concerning, she’d been corresponding with a man who collected murder memorabilia. She’d sent him a sketch of a decapitated body and a postcard expressing desire for intimacy.

These revelations seemed like exactly the kind of red flags that should keep someone locked up. Here was evidence that even after years of treatment, Morgan might still be drawn to violence, still fascinated by death.

But her attorney, Anthony Cotton, pushed back. The book, he pointed out, was one the facility had approved and provided — Morgan hadn’t smuggled it in or sought it out against the rules. The staff knew about her correspondence with the collector; it wasn’t hidden or secret. And when Morgan discovered the man was selling items she’d sent him, she cut off contact herself. These weren’t signs of a dangerous person, Cotton argued, but of a young woman navigating complex emotions and relationships while under constant supervision.

Judge Bohren ultimately sided with the defense. The state, he ruled, hadn’t met its burden of proving Morgan posed a clear danger to herself or others.

On July 31, 2025, Morgan appeared virtually in Waukesha County court for what her attorney hoped would be her final hearing. Judge Scott Wagner announced his decision: she would be released to a group home with GPS monitoring and 24-hour supervision. She would have to follow strict rules about where she could go and who she could see. Every movement would be tracked.

A facility in Sun Prairie, Wisconsin, initially agreed to take her but then declined due to negative publicity they were receiving about the potential move. Nobody wanted to be the community that housed the Slender Man stabber. She ended up in a group home in Madison instead — the same city where, just months later, she would cut off her ankle monitor and disappear.

The System’s Failure

Looking back at what happened this weekend, the failures are glaring.

The GPS monitor was supposed to be Morgan’s electronic leash, a constant signal telling authorities exactly where she was at all times. But when the Department of Corrections received an alert that the bracelet was “malfunctioning” on Saturday night, it took two hours before anyone even checked on her. Two hours during which Morgan was cutting the device off and preparing to flee.

The group home was supposed to be providing 24-hour supervision. But a 43-year-old man had apparently been sneaking through Morgan’s window on multiple occasions without anyone noticing. The oversight that was supposed to make her release safe clearly wasn’t as tight as the court had been led to believe.

And the communication between agencies — the Department of Corrections, the group home, the Madison Police — broke down completely. An apprehension request was issued at midnight but never made it to the police department that should have been searching for her. For twelve hours, Morgan Geyser was a fugitive that nobody was looking for.

The district attorney’s office had warned this might happen. “Not only should she have been in custody from 2014 forward, but also, attorney Abbey Nickolie argued vehemently for her not to be released to conditional release in I believe it was January of this year,” Waukesha County District Attorney Lesli Boese told reporters after Morgan’s capture.

The prosecutors never believed Morgan was ready. They fought against her release at every hearing. And now, less than a year after she won her freedom, she’s sitting in an Illinois jail cell, having proven their concerns were justified.

What Happens Now

Geyser appeared in court Monday and was ordered to be detained at Cook County Jail. Her extradition hearing is scheduled for Tuesday in Cook County, Illinois.

Posen Police Chief William Alexander said Geyser is not facing any local charges in Illinois, because additional charges would only prolong the process of sending her back to Wisconsin. The priority right now is getting her back to the state where she committed her original crime and where her conditional release was granted.

Once she’s back in Wisconsin, the real legal battle begins.

District Attorney Boese said her office “fully” supports a petition to revoke Geyser’s conditional release. That petition would have to be filed by the state Department of Health Services, which has custody of Morgan. Boese outlined what would happen next: “We will go before a judge to make a decision whether or not she will be returned to conditional release or whether she will be returned to institutionalized care, which is where she came from.”

If her release is revoked, Geyser would be returned to full-time institutionalized care — back behind the walls of Winnebago Mental Health Institute, where she spent nearly seven years before winning the freedom she just threw away.

It’s hard to imagine any judge looking at what happened this weekend and deciding that conditional release should continue. Morgan cut off her ankle monitor with scissors. She fled across state lines with a man who’d been sneaking into her room. She evaded capture for nearly twenty-four hours. She didn’t turn herself in — she had to be found sleeping behind a truck stop, only giving up her identity when she realized the officers weren’t going to let her go without it.

Everything her attorney worked for, every argument about rehabilitation and readiness for reintegration — it all collapsed in a single weekend.

The Other Girl

While Morgan dominated headlines this weekend, another young woman has been quietly living the life Morgan was supposed to have.

Anissa Weier was the other twelve-year-old in those woods in 2014. She didn’t hold the knife — Morgan did — but she urged her on. She helped plan the attack. She helped lure Payton to the park. When Morgan hesitated, Anissa told her to go ahead with it.

Anissa pleaded guilty to attempted second-degree intentional homicide. She was also sent to Winnebago Mental Health Institute, but her sentence was shorter — 25 years. And in 2021, after serving just four years, she was granted conditional release to her father’s home.

Since then, Anissa has done everything Morgan was supposed to do. She wears a GPS monitor. She follows the rules of her supervision. She stays out of trouble. By all accounts, she’s successfully reintegrated into society. She hasn’t reoffended, hasn’t made headlines, hasn’t become the danger many feared she would be.

Her quiet success was supposed to be the roadmap for Morgan — proof that someone involved in such a horrific crime might eventually lead a normal life with proper treatment and supervision. The two girls committed the same crime together, received similar sentences, underwent similar treatment. If Anissa could make it work, why couldn’t Morgan?

This weekend answered that question, at least for now. Anissa Weier is still living quietly under supervision, following the rules, rebuilding her life. Morgan Geyser is in a Cook County jail cell, waiting to be sent back to Wisconsin to face the consequences of running.

The difference might come down to something as simple as judgment — the ability to understand that cutting off your ankle monitor and fleeing across state lines will only make things worse. Or it might point to something deeper, some fundamental difference in how the two women have processed what they did and what they need to do to move forward.

Whatever the reason, Morgan’s escape has made it that much harder for anyone else in her situation to argue for conditional release. Every future petition will be met with the memory of this weekend — the scissors, the bus ride, the truck stop in Posen.

The Monster That Started It All

In all the coverage of Morgan’s escape and capture, Slender Man himself almost becomes an afterthought. But he’s still present in the background of this story, the fictional boogeyman who set everything in motion.

Eric Knudsen created Slender Man in 2009 as a piece of digital art for an online contest. The figure was simple but deeply unsettling: an abnormally tall, thin man in a black suit with no facial features, sometimes depicted with tentacle-like appendages extending from his back. Knudsen photo-edited him into the backgrounds of ordinary pictures — children playing in parks, friends gathered at parties — always at the edge of perception, always watching.

The character spread through internet forums as people added their own stories, their own details, their own terrifying embellishments. He became a collaborative creation, growing more elaborate with each retelling. Some said he kidnapped children. Others claimed he could teleport, control minds, or drive people insane just by being near them. Fake documentary footage made him seem almost real. For most people, it was entertainment — a modern campfire story shared through screens.

For twelve-year-old Morgan Geyser, whose mind was already struggling to distinguish between what was real and what wasn’t, Slender Man became something else entirely. She heard voices. She saw things that weren’t there. She believed Slender Man visited her, threatened her, demanded she prove her loyalty or watch her family suffer.

The psychiatric treatment that followed was supposed to dispel those delusions forever. Seven years of medication, therapy, and institutional care. The voices went quiet. The hallucinations stopped. Slender Man no longer visited.

A media professor told CNN that while Slender Man’s popularity has declined since the early to mid-2010s, he “can anecdotally say that he still performs the role of boogeyman on playgrounds.” Kids still know who he is. The story still gets passed around. But for most people, he remains what he always was — a scary story, nothing more.

Morgan Geyser’s relationship with Slender Man is different. She built her identity around him, committed attempted murder because of him, spent years in a psychiatric hospital being treated for the delusions he represented. Even if she no longer believes in him, even if the medication has silenced the voices that once told her he was real, Slender Man will always be part of her story. Every headline about her mentions him. Every article recaps the 2014 stabbing. She can’t escape him any more than she can escape what she did in those woods.

The Question That Won’t Go Away

As Morgan Geyser sits in an Illinois jail cell awaiting extradition back to Wisconsin, the question that haunted her case from the beginning remains unanswered: can someone who once believed so completely in monsters ever be trusted to live among the rest of us?

The psychiatric experts said yes. They testified that Morgan had made remarkable progress, that her symptoms were under control, that she understood what she’d done and why it was wrong. They believed seven years of treatment had transformed her from a dangerous, delusional child into a stable young woman capable of living under supervision in the community.

The prosecutors said no. They argued that Morgan should never have been released, that the risk was too great, that the crime she committed was too severe to ever justify conditional freedom. They pointed to the murder memorabilia correspondence, the decapitated body sketch, the book about organ sales. They said the warning signs were still there.

This weekend, Morgan answered the question herself — not with words, but with actions. She cut off her ankle monitor. She fled across state lines. She traveled 170 miles before police found her sleeping behind a truck stop. She didn’t turn herself in even when her own attorney begged her to.

Maybe she was just a young woman who felt trapped and made an impulsive decision. Maybe the restrictions of supervised living felt unbearable after years of institutionalization. Maybe Chad Mecca convinced her that running was the answer. Maybe she just wanted to feel free, even if only for a day.

Or maybe the prosecutors were right all along. Maybe the progress everyone thought they saw wasn’t as solid as it appeared. Maybe the delusions are quieter now but not gone. Maybe Morgan Geyser will always be someone who needs to be watched, monitored, controlled — because the alternative is too dangerous to risk.

The GPS bracelet she cut off with scissors was supposed to be the answer to all these questions. It was supposed to prove that conditional release could work, that supervision technology could keep the community safe while giving Morgan a chance at something like a normal life. Instead, it’s just another piece of evidence — proof that even constant monitoring can’t prevent someone from running if they really want to.

The court will decide what happens next. Morgan will either be returned to conditional release with even stricter supervision, or she’ll go back to Winnebago Mental Health Institute for the foreseeable future. Given what happened this weekend, the second option seems far more likely.

Payton Leutner will keep living her life, carrying the scars — visible and invisible — from that morning in 2014. Her family will keep watching, keep worrying, keep hoping that the system will protect them from the girl who once tried to kill their daughter.

And Morgan Geyser will remain what she’s been since she was twelve years old: a permanent example of what happens when internet mythology meets mental illness, when fiction bleeds into reality, when a child picks up a knife and decides that a faceless monster in a black suit is more real than the friend standing in front of her.
