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.

In June 2010, German scientists said that they believed there was evidence that he had died of sickle cell disease. Other experts, however, rejected the hypothesis of homozygous sickle cell disease based on survival beyond the age of 5 and the location of the osteonecrosis, which is characteristic of Freiberg-Kohler syndrome rather than sickle-cell disease. Research conducted in 2005 by archaeologists, radiologists, and geneticists, who performed CT scans on the mummy, found that he was not killed by a blow to the head, as previously thought. New CT images discovered congenital flaws, which are more common among the children of incest. Siblings are more likely to pass on twin copies of deleterious alleles, which is why children of incest more commonly manifest genetic defects. It is suspected he also had a partially cleft palate, another congenital defect.
