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.
Tiye
Her mummified remains were found adjacent to two other mummies in an opposite side chamber of Amenhotep II in KV35 by Victor Loret in 1898. The two other mummies were a young boy who died at around the age of ten, thought to be Webensenu or Prince Thutmose and another, younger unknown woman. All three were found together, lying naked side-by-side and unidentified in a small antechamber of the tomb. The younger unknown woman had been extensively damaged by grave robbers, her chest and face smashed in. This was an extremely callous act, as a damaged mummy could not enter the afterlife. At first, researchers were unable to identify both female mummies and they were instead given names with Tiye being labelled as the 'Elder Lady' while the other woman was 'The Younger Lady'. Several researchers argued that the Elder Lady was Queen Tiye. Some noted that miniature coffins inscribed with her name were found at the tomb of her grandson, Tutankhamun, as memento from a beloved grandmother. There were also some scholars who were skeptical about this theory such as British scholars Aidan Dodson and Dyan Hilton, who once stated that "it seems very unlikely that her mummy could be the so-called 'Elder Lady' in the tomb of Amenhotep II."
