Irish Man's Death Ruled Spontaneous Combustion

Posted by samzenpus on from the some-like-it-hot dept.

chrb writes "BBC News is reporting that an Irish coroner has ruled that a dead man was killed by spontaneous human combustion. The controversial finding is a first in Irish history. From the article: 'West Galway coroner Dr Ciaran McLoughlin said it was the first time in 25 years of investigating deaths that he had recorded such a verdict. Michael Faherty, 76, died at his home in Galway on 22 December 2010. Deaths attributed by some to "spontaneous combustion" occur when a living human body is burned without an apparent external source of ignition.'"

    I looked into this when I first read about it. Apparently a disproportionate amount of "spontaneous combustion" cases are older people found next to fire places, this man included. I was not able to find details that would rule out an existing fire in the fireplace contributing to the cause, like an absence of ashes. It's speculated that these cases are people who had a stroke or heart attack while warming themselves by the fire, after which a small spark flies out and eventually smolders the entire body.

    "The court heard Mr Faherty had been found lying on his back with his head closest to an open fireplace." ... "He said Professor Bernard Knight, in his book on forensic pathology, had written about spontaneous combustion and noted that such reported cases were almost always near an open fireplace or chimney." ... ""There is a source of ignition somewhere, but because the body is so badly destroyed the source can't be found," he said." The obvious solution is that his hair caught on fire; perhaps with some sort of flammable substance in his hair like an aerosol or hair gel and the damage was too great for forensics to pick it up.

    The best explanation I've heard is the wick effect.

    The "wick effect" hypothesis suggests that a small external flame source, such as a burning cigarette, chars the clothing of the victim at a location, splitting the skin and releasing subcutaneous fat, which is in turn absorbed into the burned clothing, acting as a wick. This combustion can continue for as long as the fuel is available. This hypothesis has been successfully tested with animal tissue (pig) and is consistent with evidence recovered from cases of human combustion.[5][6] The human body typically has enough stored energy in fat and other chemical stores to fully combust the body; even lean people have several pounds of fat in their tissues.

    The presumption is that the person dies of other causes, and then a lit cigarette or some other ignition source starts the process. And you're right, from what I've heard, a high percentage of SHC victims were known to be heavy drinkers, which would only add more fuel to the fire.

    1kg of lard contains 37700kJ and can therefore vaporize almost 16,9kg of water. 5kg of lard can vaporize 84kg of water.

    Those 5kg just about cover the essential body fat, i.e the fat we need in/around our brain, skin, joints, etc.
