Researchers believe they have identified the cause of death of an ancient Egyptian king thought to have ruled from around 1186 B.C. to 1155 B.C. CT scans of king Ramesses III's mummy show a severe wound in his throat, likely the result of an assassination conspiracy explained in court documents but unconfirmed until now. The researchers published their findings Monday in the British Medical Journal. They also think they may have found the body of Prince Pentawere, one of the king's sons believed to have been involved in the conspiracy.
