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.
Ankhesenamun
After her father's death and the short reigns of Smenkhkare and Neferneferuaten, she became the wife of Tutankhamun. Following their marriage, the couple honored the deities of the restored religion by changing their names to Tutankhamun and Ankhesenamun. The couple appear to have had two stillborn daughters. As Tutankhamun's only known wife was Ankhesenamun, it is highly likely the fetuses found in Tutankhamun's tomb are her daughters. Some time in the ninth year of his reign, at about the age of eighteen, Tutankhamun died suddenly, leaving Ankhesenamun alone without an heir at about age twenty-one.
