FAYETTEVILLE, Ga. - Pro wrestler Chris Benoit strangled his wife, suffocated his 7-year-old son and placed a Bible next to their bodies before hanging himself with the pulley of a weight machine, authorities said Tuesday.

Investigators found prescription anabolic steroids in the house and want to know whether the muscle man nicknamed “The Canadian Crippler” was unhinged by the bodybuilding drugs, which can cause paranoia, depression and explosive outbursts known as “roid rage.”

Authorities offered no motive for the killings, which were spread out over a weekend, and would not discuss Benoit’s state of mind. No suicide note was found.
