"It's their job to look through everything," Arora said. "I want them to look through everything, so if there is an acquittal in this case there will be no more doubt about anything that Dr. Astin's done," Arora said.

Astin pleaded not guilty at his first court appearance.

Police have said Benoit strangled his wife and son, placing Bibles next to the bodies, and then hung himself on a piece of exercise equipment in his suburban Atlanta home the weekend of June 22.

Authorities found anabolic steroids in Benoit's home, leading officials to wonder whether the drugs played a role in the killings. Some experts believe steroids can cause paranoia, depression and violent outbursts known as "roid rage."

Another court affidavit said Astin prescribed a 10-month supply of anabolic steroids to Benoit every three to four weeks between May 2006 and May 2007.

Astin has told the AP he prescribed testosterone for Benoit, a longtime friend, in the past but has not said what, if any, medications he prescribed when Benoit visited his office June 22, the day authorities believe Benoit killed his wife.

Since the deaths, 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.

Some of the tests have been completed, but authorities are keeping the results secret until all the tests are complete.
