This is one of the most famous photos from an alleged case of spontaneous human combustion. On December 5, 1966, 92-year-old retired doctor John Bentley died from a fire of unknown origin in Coudersport, Pennsylvania. The elderly man walked with the aid of a walking frame, clearly visible in the photo. The fire apparently was confined to a small area of the doctor's bathroom, which burned a hole in the floor. Most of his body was reduced to ash.
