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.
Valley of the Kings
At the same time, powerful and influential nobles began to be buried with the royal family; the most famous of these tombs is the joint tomb of Yuya and Tjuyu, KV46. They were possibly the parents of Queen Tiy. Until the discovery of the tomb of Tutankhamun, this was the best-preserved of the tombs that had been discovered in the Valley.
