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.

He covered the opening of the tomb of Tutankhamun as correspondent for the "Daily Mail, "in direct opposition to Howard Carter and Lord Carnarvon's attempts with "The Times "to monopolise the story, a monopoly which he regarded as both wrong and politically damaging to British relations with Egypt at a time when nationalist feeling was strong. At the tomb of Tutankhamun he saw Lord Carnarvon joke as he prepared to enter the tomb, and is reported as saying 'if he goes down in that spirit, I give him six weeks to live'.
