Egyptologist Bob Brier suggested that Ay murdered Tutankhamun in order to usurp the throne, a claim which was based on X-ray examinations of the body done in 1968. He also alleged that Ankhesenamun and the Hittite prince she was about to marry were also murdered at his orders. This murder theory was not accepted by all scholars, and further analysis of the x-rays, along with CT scans taken in 2005, found no evidence to suggest that Tutankhamun died from a blow to the head as Brier had theorized.
