Poof: Man Dies Of Internal Combustion In Ireland

From the BBC News: A man who burned to death in his home died as a result of spontaneous combustion, an Irish coroner has ruled.
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.
Typically police or fire investigators find burned corpses but no burned furniture.
An inquest in Galway on Thursday heard how investigators had been baffled as to the cause of Mr Faherty's death at his home at Clareview Park, Ballybane.
Forensic experts found that a fire in the fireplace of the sitting room where the badly burnt body was found, had not been the cause of the blaze that killed Mr Faherty.
The court was told that no trace of an accelerant had been found and there had been nothing to suggest foul play.
The court heard Mr Faherty had been found lying on his back with his head closest to an open fireplace.
The fire had been confined to the sitting room. The only damage was to the body, which was totally burnt, the ceiling above him and the floor underneath him.

I've read about these cases, but I am not sure if bodies can just burst into flames, especially since the body is made up of over 90% water.
But stranger things have happened.
