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.
Tutankhamun's mummy
Under commission of George Herbert, 5th Earl of Carnarvon, who is commonly called just Lord Carnarvon, Howard Carter and his team set out to Egypt in 1922 to discover the tomb of Tutankhamun, and because of other recent discoveries during that time in a particular area of the Valley of the Kings, Carter believed he had a good idea of where he would find it. Theodore M. Davis, an archeologist contemporary with Carter, discovered pottery with Tutankhamun's name a short distance from where Carter would on November 4, 1922 discover KV62.
