Clues:
Many other artifacts in Tut's tomb suggest that they were not meant for him.
King Tut and his wife Ankhesenumun did not have any children.
Tut was young and not prepared to die like an old pharaoh would have been. A tomb would not have been ready.
Tut was the last of the bloodline of his family. Whoever married his wife would surely be king.
Tut might have died of a plague that was causing many deaths in Egypt.
Another reason for suspicion regarding Tut's death was the hurried burial.
Some think that Aye had to justify his rise to the throne in light of the events surrounding the king's death and so he had his picture painted on Tut's wall.
The wooden coffin was made for another king but was used for Tut instead.
Aye arranged for the wall to be painted with himself (as king) giving the last rites.
Aye did not allow his future young wife to be painted on the walls of Tut's tomb, though this was the custom.
When Aye took the throne, he had no children to succeed him.
In the picture on the wall of the tomb, Aye is wearing a crown, suggesting that he is the rightful heir to the throne. This is very unusual in Egyptian art.
Aye would not have wanted to have a Hittite king. He knew the Hittite prince would appoint his own advisors--and so Aye would be out of a job.
It had to be someone with the military power to order the murder of the Hittite prince. Aye had the motive and power to do this.
Tey had already held a place of prominence in the Egyptian society as Nefertiti's confidant.
Tey might have had the motive for murdering Ankhesenamun.
Tey certainly would not have taken a back seat to another younger wife.
Under Tut's general (Horemheb) many of the Hittite warriors were killed in battle.
Horemheb would not have wanted his enemy to rule over Egypt.
Horemheb had the motive and the power as a general to order the murder of the Hittite prince.
He did many great things for Egypt. Does that mean that he is innocent of murder?
Horemheb certainly did not want Aye to keep the younger Ankhesenamun as his wife. She was young enough to have children who would ascend the throne.
Did Horemheb believe that he could grab the throne when Aye died four years later?
His power as general and the backing of his powerful army made sure he could take the throne upon Aye's death.
In her letter, Ankhesenamun doesn't name any names but she does imply that she is being forced to marry a servant.
One of two things is sure: either her tomb has not yet been found, or she was not given a proper burial.
Was Ankhesenamun referring to Aye as the servant she didn't want to marry?
Was she simply punished for offering the throne to a foreigner (something considered treasonous)?
Could the murderer of Tut be Ankhesenamun? Maybe she wanted to rule Egypt herself through a foreigner?
Did Ankhesnamun die of a plague that was consuming Egypt at the time?
The Hittites had a powerful military and would definitely back her up, if needed.
If she killed Tut, Aye would be seen as the defender of Egypt's liberty against a scheming queen who murdered her own husband.
