The results of toxicology tests conducted on the body of former pro wrestler Chris Benoit will be revealed at a press conference Tuesday at 2:30 p.m., Georgia Bureau of Investigation spokesman John Bankhead said.

The test results are expected to shed more light on Benoit's last moments. Authorities said Benoit killed his wife and seven-year-old son in their metro Atlanta home last month, placed Bibles next to their bodies and then hanged himself on the cable of a weight machine.

Anabolic steroids were found in the Benoits' gated home, leading officials to wonder if the drugs played a role in the killings. Some experts believe steroids can cause paranoia, depression and violent outbursts known as "roid rage."

Toxicology tests have been conducted on Benoit's body to determine if steroids or other drugs were present. Blood-alcohol tests also were conducted on his body, and chemical tests were conducted on the bodies of the wife and son.

The results of the test will released by Dr. Kris Sperry, the state's chief medical examiner, said Bankhead.

Fueling the speculation that steroids may have been involved in the deaths, federal authorities charged Benoit's personal physician, Dr. Phil Astin, with improperly prescribing painkillers and other drugs to two patients other than Benoit. He has pleaded not guilty.

Investigators office has also been raided Astin's office several times since the deaths, seizing prescription records and other medical documents.

Before he was charged, Astin told the AP he prescribed testosterone for Benoit, a longtime friend, in the past. He would not say what, if any, medications he prescribed when Benoit visited his office June 22, the day authorities believe Benoit killed his wife.
