The History of Human Combustion

There are hundreds of reported spontaneous human combustion cases. Only around 12 have been investigated in actual detail. One of the world's most heavily investigated case is that of 67 year old Mary Reeser, from St. Petersburg, Florida. The tops of her walls were stained with smoke and the electric switches all warped. Her skull was quote shrunken to the size of a cup but it sounds like it would be the brain.
