Pro wrestler Chris Benoit was over-prescribed testosterone, say federal prosecutors.
Tests conducted by authorities showed that the WWE star had roughly 10 times the normal level of the hormone in his system when he died, the Associated Press reports
Prosecutors had subsequently filed criminal papers against Dr. Phil Astin, Benoit’s personal physician, alleging that the amount of testosterone he prescribed far exceeded the normal amount for the hormone disorder for which Benoit reportedly received treatment.
Astin has also been charged with over-prescribing medication to two other patients – and more charges are expected.
According to authorities, the WWE star injected himself with testosterone before killing his wife and son in their suburban Atlanta home on June 24. The wrestler then committed suicide.
Reports also show that Benoit, 40, sedated his son, Daniel, 7, with Xanax before strangling him.
Many theories suggest that steroids influenced Benoit’s actions. Experts believe that using testosterone may cause paranoia, depression and violent outbursts or expressions.
Prosecutors investigating the case report that over a year – ending one month before the June murder-suicide – Astin wrote Benoit seven prescriptions, an amount that, according to the Food and Drug Administration, exceeds dosage guidelines by more than 50 percent.
