Pro wrestler murder-suicide probe continues

Authorities in Fayetteville are looking into whether Chris Benoit was on steroids before killing his wife and son, then later committing suicide. Officials say the pro wrestler strangled his wife Nancy last Friday, suffocated his 7-year-old son on Saturday, then later killed himself by hanging. Investigators found prescription anabolic steroids in the house. The drugs have been known to cause paranoia, depression and outbursts known as "roid rage". Benoit was a wrestler with World Wrestling Entertainment.
