Tutankhamun's body may have spontaneously combusted due to a botched mummification, British scientists claim in a new programme. Egyptologist Chris Naunton and a team of forensic scientists performed a "virtual autopsy" on the young pharaoh in a Channel 4 television documentary, Tutankhamun: The Mystery of The Burnt Mummy , which was broadcast yesterday. The experts used x-ray and computerised tomography (CT) scanning data to show a distinct pattern of injuries down one side of his body. They also examined a fragment of the pharaoh's flesh. They claimed chemical tests confirmed that the mummy burned while still sealed inside his coffin. Fire investigators demonstrated how a chemical reaction of the embalming oils used on Tutankhamun's mummy led to his spontaneous combustion. "Despite all the attention Tut's mummy has received over the years, the full extent of its strange condition has largely been overlooked," Naunton said. "The charring and possibility that a botched mummification led the body spontaneously combusting shortly after burial was entirely unexpected, something of a revelation in fact. "What the project shows is that when it comes to ancient material there is always more to learn, and there probably will in the future, but with this study we have taken a big step forward in terms of understanding what happened at the end of Tut's life." Tutankhamun died aged about 19, after 10 years of rule between 1333BC and 1324BC. His nearly intact tomb was discovered in 1922 by British pair Howard Carter and George Carnarvon. In 2010, DNA testing and CT scans revealed that he had had malaria and suffered from a club foot.
