Investigators have new clues but no final answers about what may have led wrestler Chris Benoit to kill his wife and young son and then himself.
The chief medical examiner for the Georgia Bureau of Investigation released autopsy results Tuesday for all three members of the Benoit family.
Doctors confirmed Tuesday that Benoit had taken the anti-depressant Xanax along with the pain-killer Hydrocordone the weekend of the attacks.
He also according to the report had been injecting testosterone.
"How frequently, how much, not something that can be answered," said Chief Medical Examiner Dr. Kris Sperry.
At the time of his death anabolic steroids were found in Benoit's Atlanta home.
Some experts have speculated steroids can cause paranoia, depression and violent outbursts known as "roid rage."
"No evidence shows that elevated use of testosterone leads to rages," said Dr. Sperry.
Medical examiners also found high levels of Xanax during their examination of 7-year-old Daniel Benoit indicating.
"Daniel was sedated at time he was murdered," Sperry said.
The same drug along with Hydrocordone was evident in Benoit's wife Nancy but neither was apparently at questionable levels.
The medical examiners report showed that Benoit had 10-times the normal amount of testosterone in his body at the time of his death.
But the doctor also was quick to point out at this point there is no evidence steroids played a role in the deaths of his wife and son.
