The Case of King Tut – CT Scans and DNA Forensics of Tutankhamun’s Mummy

The Case of King Tut – CT Scans and DNA Forensics of Tutankhamun’s Mummy

Tabea Tietz
On January 6, 2005, the mummy of Tutankhamun (c. 1355-1346 B.C.) was removed from its tomb in the Valley of the Kings to be subject of a state-of-the-art non invasive CT scan, which gave evidence that the young king had suffered a compound left leg fracture shortly before his death, and that the leg had become infected, and did not support the popular assumption that the king had been murdered. The Discovery…
