ATLANTA AP – Pro wrestler Chris Benoit strangled his wife and smothered his son before hanging himself in his weight room, a law enforcement official close to the investigation told The Associated Press on Tuesday.

Authorities also said they are investigating whether steroids may have been a factor in the deaths of Benoit, his wife and their 7-year-old son. Steroid abuse has been linked to depression, paranoia, and aggressive behavior or angry outbursts known as “roid rage.”
