Tutankhamun's mummy
Detective Michael R. King and FBI profiler Gregory M. Cooper came together with an actual Egyptologist to form their own theory which was that Tutankhamun was murdered. With the use of forensic evidence and their extensive backgrounds in criminology, they came to the conclusion that he was likely murdered by one of his closest advisors, Ay. Ay did succeed Tutankhamun on the throne, so they used that as the motivation for the murder.
Bernard Bruyère
One morning in October 1922, British archaeologist and Egyptologist Howard Carter visited the site to express his despair to his colleague, Bruyère: Lord Carnarvon, Carter's patron, had ended their collaboration, giving Carter a deadline to find something of value on the expedition they had just begun. Bruyère, who followed the excavations of the English with interest, suggested that they explore a spot they had not yet prospected: the foot of the entrance to Ramesses VI's tomb. There, they discovered the Tomb of Tutankhamun.
