tutakamun deid when he was about 18, he probally wasn't murdered, but died from an infection in a broken leg!
That's correct. I used to be a proponent of the "Tut assassination" theory but the CT scans taken back in January have more or less ruled that out. Of course the boy-king may have been poisoned, but there's absolutely no evidence for that, so I personally discount it.
The most recent issue of National Geographic
has some fantastic photos of the CT scans, and in them you can clearly see the fractures Tut suffered to his legs shortly before death; also evident is the patella (knee-cap bone) missing from the boy-king's left leg (this was actually found nestled in one of his hands when he was originally unwrapped). It seems clear Tut suffered massive injuries to his legs. The fractures themselves would not have been fatal, but the onset of gangrenous infections certainly could have been.
As detailed as the CT scans are, even they are not enough to tell us with certainty how Tutankhamun Nebkheperure perished. Most likely it was some sort of accident, such as with a chariot, but there is no evidence of murder.
remember anakansamun wrote to the Hititiet (cant spell it! OOPS) King explaning about Tuts murder, she does mention Ay, (i think?)
For one thing we cannot even be certain that the author of the letter is Ankhesenamun; there is no name attached to it. But I'm like you (and many other people, including historians and Egyptologists) and believe it was indeed Tut's widow. The royal lady who wrote the letter never mentions "murder" or "assassination." The wording in the relevant portion of the letter is (and for this I must thank Osiris II for digging up the quote in an old forum elsewhere):
He who was my husband has died. A son I have not! Never shall I take a servant of mine and make him my husband!
Ay is never mentioned, nor is any other royal or courtier to help us put the pieces together. By "servant" the royal lady is not necessarily referring to a lowly household official but a "servant" of the government, and indeed it most probably is Ay. Ankhesenamun disappears from history soon after Ay takes the throne; most likely Ay succeeded in marrying her, thereby adding legitimacy to his accension, and thereafter she served no purpose.
Smenkhare is another matter. He may have been Tut's brother, some believe him to have been Akhenaten's brother, and others believe him to have been actually Nefertiti. In other words, we as yet have no solid idea of who this person was. There is evidence of his marrying a daughter of Akhenaten, and indeed some believe Smenkhare to be the father of Tut. A lot remains to be learned about Smenkhare before anyone can make conclusive judgements.
I will wholly agree with you that Ay and Horemheb were two very powerful and ambitious men. Their long military careers probably instilled these qualities in them, not to mention their taste for power. I for one, however, now have to agree with the evidence, and no longer believe them to have been culpable in Tut's death.
