"The charring and possibility that a botched mummification led to the body spontaneously combusting shortly after burial was entirely unexpected - something of a revelation," said Naunton, as quoted in the Independent.
Spontaneous human combustion, once considered an impossibility, has received renewed interest from scientists worldwide. British biologist and author Brian Ford believes that flammable acetone produced by a body could - in the presence of a spark from static electricity or some other ignition source - cause a human body to catch fire and burn.
And by analyzing the injuries sustained by car-crash victims, forensic scientists have now shed light on the events surrounding the death of the boy king, who is believed to have been just 17 years old when he died.
Investigators were able to determine that the young pharaoh was on his knees when a horrific chariot accident smashed his rib cage, shattered his pelvis and crushed many of his internal organs, including his heart, according to the Guardian. This may explain why his heart was never found in his mummified body.
