Late wrestling star Chris Benoit had 10 times the normal level of testosterone in his body when he murdered his wife and son in June, according to investigators.
The WWE fighter, 40, asphyxiated his wife Nancy and son Daniel on June 22 and 23, respectively, before hanging himself a day later at the family's home in Georgia.
On Tuesday, the Georgia Bureau of Investigation confirmed that Benoit's body contained testosterone, which he injected shortly before he died, the painkiller hydrocodone and anti-anxiety drug Xanax.
However, Georgia's most senior medical examiner, Dr. Kris Sperry, pointed out there was no evidence to prove steroids in Benoit's system contributed to Nancy and 7-year-old Daniel's deaths.
Sperry said, "An elevation of that ratio does not translate into something abnormal in a person's thought process or behavior."
Daniel had been sedated with Xanax, while Nancy had Xanax, hydrocodone and another painkiller, hydromorphone, in her system.
Benoit's physician, Dr. Phil Astin, has been charged with improperly prescribing drugs, including Percocet, Xanax, Lorcet and Vicoprofen, between April 2004 and September 2005.
