Federal drug agents raided the office of a doctor who prescribed testosterone to Chris Benoit.
The raid at Dr. Phil Astin's office in Carrollton began Wednesday night and concluded early Thursday, said agent Chuvalo Truesdell, a spokesman for the Drug Enforcement Administration. The search warrant had been obtained in connection with the Chris Benoit investigation, he said. No arrests were made.
Hours before the raid, Astin told The Associated Press he had treated Benoit for low testosterone levels, which he said likely originated from previous steroid use.
Among other things, investigators were looking for Benoit's medical records to see if he had been prescribed steroids and, if so, whether that prescription was appropriate, according to a law enforcement official speaking on condition of anonymity because records in the case remain sealed.
Astin did not return repeated calls to his cell phone from The Associated Press on Thursday.
Astin prescribed testosterone for Benoit, a longtime friend, in the past but would not say what, if any, medications he prescribed when Benoit visited his office Friday, the day on which he later killed his wife, Nancy Benoit.
Benoit strangled his wife and smothered son during the weekend, placing Bibles next to their bodies, before hanging himself on the cable of a weight-machine in his home, authorities said. No motive was offered for the killings, which were discovered Monday.
Anabolic steroids were found in Benoit's home, leading officials to wonder whether the drugs played a role in the slayings. Some experts believe steroids cause paranoia, depression and violent outbursts known as "roid rage."
Vince McMahon denied this on The Today Show this morning, labeling Benoit as a "monster" and not pointing to drugs as the basis for his attacks.
