Before Chris Benoit killed himself and his family, the Drug Enforcement Administration knew he was an “excessive purchaser of injectable steroids,” documents show. According to a June 29 search warrant affidavit posted on The Smoking Gun, Benoit’s physician, Dr. Phil Astin, prescribed Benoit, on average, “a 10-month supply of anabolic steroids … every three to four weeks” from May 2006 to May 2007. Astin surrendered in Atlanta Monday after being charged with improperly dispensing painkillers and other drugs, his lawyer said. According to a seven-count indictment, Astin dispensed drugs including Percocet, Xanax, Lorcet and Vicoprofen between April 2004 and September 2005 to recipients identified by the initials O.G. and M.J., the Associated Press reports. The initials of WWE star Benoit were not listed. A sealed criminal complaint was also filed, and a law enforcement official close to the case told the AP that case involves steroids.
