In a small motel in a town in the United States, the wife of the motel owner, Mr. Miller, suddenly ignited in the middle of the night. Mrs. Miller was found near the fireplace, her body almost completely burned away, leaving only parts of her skull, limbs, and a few vertebrae. This mysterious incident sparked a heated courtroom debate, ultimately resulting in Mr. Miller being acquitted. Similar spontaneous combustion events have occurred around the world, involving figures such as the Italian priest, Father Bédard, and American professor, Hamilton. These incidents not only challenge the understanding of the scientific community but also ignite widespread discussions about supernatural phenomena.

To this day, human spontaneous combustion has not been officially recognized by the scientific community, even though many pieces of evidence suggest these events are real; the causes remain unclear. Scientists have proposed various possible explanations, including intestinal gases, the production of flammable gases by the human body, and static electricity, yet conclusive evidence has yet to be found. These mysterious combustion events remain enigmas throughout history, waiting for future scientific answers.
