One of the mummies inside the Cairo Museum's Royal Mummy Room is not like the others. Among the meticulously preserved remains of Egyptian pharaohs and queens lies the corpse of Seqenenre Tao, whose mummification was hurried and incomplete. His face is brutally injured and his hands are horribly contorted. Who was this man, and what on earth happened to him? We use modern forensic techniques to examine this 3,000-year-old forgotten pharaoh and reveal the probable cause of his death.
