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.
The Younger Lady
The mummy was found adjacent to two other mummies in KV35: a young boy who died at around the age of 10, thought to be Webensenu, and another, older woman, identified as Queen Tiye by the recent DNA studies on Tutankhamun's lineage. All were found together, lying naked side-by-side and unidentified in a small antechamber of the tomb. All three mummies had been extensively damaged by ancient tomb robbers.
