Matilda Rooney’s Christmas Combustion

On Christmas Eve 1885, a peaceful night at a Seneca, Illinois farmhouse turned into a burning mystery when Matilda Rooney vanished in flames, leaving behind only ashes—and unanswered questions.

(As heard in the Weird Darkness podcast episode ‘Twas The Mystery Before Christmas.)

On Dec. 24, 1885, very strange things happened at a farmhouse in Seneca, Illinois. What began as an ordinary holiday night would become one of history’s most baffling puzzlements

Patrick and Matilda Rooney were celebrating Christmas Eve with their farmhand, John Larson. After some drinks together, Larson went up to bed. That night he woke up coughing with difficulty breathing but eventually fell back asleep.

But the next morning, Larson saw something unusual — black soot on his pillow. When he went downstairs to check on his employers, he found something disturbing. Patrick Rooney was dead in his bedroom, but his wife Matilda was missing. Then Larson looked into the kitchen and saw something horrible: a huge, blackened hole in the floor. In that hole were ashes and what appeared to be a burned human foot. This was all that remained of Matilda Rooney.

When Dr. Floyd Clendenin showed up to investigate, he found more clues. There was an odd odor in the house and greasy soot on the walls. There was a candle in the kitchen that was partially burned on the table. He found some bones in the charred hole in the floor, including a skull, and two burned feet which remained in Matilda’s shoes. What was peculiar was that while Mrs. Rooney had weighed roughly 160 pounds when alive, all of her that remained was 12 pounds of ash and bone.

The mystery grew when investigators noticed something odd: aside from the hole where Matilda’s body had lain, nothing else in the house burned. How could a fire reach temperatures hot enough to burn a person into ashes — around 2,500 degrees Fahrenheit — and not burn the entire house down?

It may have been murder, some people theorized, and both John Larson and the Rooneys’ son John emerged as suspects. But Larson’s story did not hold up — there was an outline of his body in the bed where he had been sleeping, indicating he had not budged all night. Larson died two weeks later, of inhaling the same smoke that had killed Patrick Rooney.

Scientists and doctors formulated various theories to explain what had happened. Some thought it was “spontaneous human combustion” — the notion that someone might burst into flames for no reason at all. Others theorized that Mrs. Rooney had accidentally been set on fire by the candle on the table, perhaps when she was lighting a cigarette. It was just as likely that she and her husband, who were drinking, hadn’t reacted quickly enough to extinguish the fire.

One theory proposed that after Mrs. Rooney’s clothes ignited, her body fat may have served as a candle wick, which would keep the fire burning but limited to her body alone. This phenomenon is known as the “wick effect,” and some scientists believe it can explain other puzzling cases like this one.

Mrs. Rooney’s was not the only case of its kind. Two hundred similar incidents around the world have been reported of individuals found turned to ash, while their surroundings remained largely intact. Scientists nowadays don’t think it’s possible for people to spontaneously combust, but they still aren’t entirely sure how the fires that consume them can burn so hot while remaining so contained.

The truth of what actually happened to Matilda Rooney on that Christmas Eve is a mystery. Modern scientists will tell you there had to be something that sparks the flame — humans don’t just spontaneously combust. But they still cannot fully explain why such an intense fire apparently burned only one person while leaving everything else almost untouched.

More than a century later, the peculiar story of Mrs. Rooney’s fire remains a mystery, and probably will for many Christmases to come.
