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.
Sekhem scepter
The sekhem was also utilized in temple and mortuary offering rituals. The officiant who presented the offerings often held it. In such cases the scepter was held in the right hand and was waved four or five times over the offerings while ritual recitations were being made. A gilded sekhem scepter was found in Tutankhamun's tomb. On the back of this scepter were carved five registers depicting a slaughtered bull, which may indicate that the scepter was waved five times over the offering. We are also told that, when consecrating offerings, the king used two sekhem-scepters; one for Set, and another for Horus. Elsewhere, Horus and Seth appear as "the Two Sekhems" (shmwy).
