... the body lay is burnt, but the rest of the room including the toilet was not even scorched. This shows a quick, hot flame that divorced the body in seconds. Only the bottom of one leg remained to identify this as a person. On the right there is a picture ... "Apparently the coroner in the case had never heard of the “wick effect,” in which a flaming object like a cigarette dropped on a sleeping person can slowly melt all their (quite flammable) fat until it leaks out and saturates the body, forming, in effect, a human candle or torch. It’s what forensic scientists think happens in cases of so-called “spontaneous” human combustion." (Veronique Greenwood)
