How and when did Hatsheput died?

Answer 1

For many years, it was thought that Hatsheput was killed by her stepson. However, her death was finally decided during a CT scan of the bodies found in tomb KV60 (located in the Valley of Kings) during 2007.

They were trying to find which of the mummies was Hatshepsut and at the same time, found her cause of death. There was a wooden box with her name on it that happened to contain a tooth along with her liver. The tooth they found was a secondary molar with part of a root missing, matching the DNA to the liver. The tooth they found ended up matching the jaw of one of the mummies who still had part of that root in there. That mummy happened to be one they found lying on the floor of KV60 in rags, and also considered 'fat', which was unlikely for royals even though she was found in a royal pose.

With this find, they found which mummy was Hatsheput and her cause of death. She aledgedly died of an abscessed tooth which in turn caused her to get an infection. Among that they found she also had bone cancer and Diabetes. (Furture tests are to determine a more accurate result.) Hatsheput's health probelms seemed to have put an end to her life in 1458 B.C.
