What is Spontaneous Human Combustion?
Spontaneous combustion occurs when an object -- in the case of spontaneous
human combustion, a person -- bursts into flame from a chemical reaction
within, apparently without being ignited by an external heat
source.
The first known account of spontaneous human combustion came from the Danish
anatomist Thomas Bartholin in 1663, who described how a woman in Paris "went up
in ashes and smoke" while she was sleeping. The straw mattress on which she
slept was unmarred by the fire. In 1673, a Frenchman named Jonas Dupont
published a collection of spontaneous combustion cases in his work "De
Incendiis Corporis Humani Spontaneis."
The hundreds of spontaneous human combustion accounts since that time have
followed a similar pattern: The victim is almost completely consumed, usually
inside his or her home. Coroners at the scene have sometimes noted a sweet,
smoky smell in the room where the incident occurred.
What makes the charred bodies in the photos of spontaneous human combustion so
peculiar is that the extremities often remain intact. Although the torso and
head are charred beyond recognition, the hands, feet, and/or part of the legs
may be unburned. Also, the room around the person shows little or no signs of a
fire, aside from a greasy residue that is sometimes left on furniture and
walls. In rare cases, the internal organs of a victim remain untouched while
the outside of the body is charred.
Not all spontaneous human combustion victims simply burst into flames. Some
develop strange burns on their body which have no obvious source, or emanate
smoke from their body when no fire is present. And not every person who has
caught fire has died -- a small percentage of people have actually survived
what has been called their spontaneous combustion.
