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.
Yuya
The tomb of Yuya and Tjuyu was, until the discovery of Tutankhamun's, one of the most spectacular ever found in the Valley of the Kings despite Yuya not even being a pharaoh. Although the burial site was robbed in antiquity, many objects not considered worth plundering by the robbers remained. Both the mummies were largely intact and were in an amazing state of preservation. Their faces in particular were relatively undistorted by the process of mummification, and provide an extraordinary insight into the actual appearance of the deceased while alive (see photographs).
