The Georgia Bureau of Investigation says steroids were found in the body of pro wrestler Chris Benoit, who killed his wife and young son last month before hanging himself.

Benoit's wife Nancy had "therapeutic levels" of Xanax and hydrocodone — a generic Vicodin — in her system when she died.

Investigators said they did find extremely elevated levels of testosterone in his bloodstream — enough to say that Benoit was using the hormone when he died. They claim this is evidence that the wrestler was injecting himself with the steroid.

Investigators have concluded that Chris Benoit's seven-year-old son Daniel was sedated with Xanax at the time he was killed. The Medical Examiner said they could not perform tests for steroids or human growth hormones on Daniel because of a lack of urine available to do those tests.
