How did Chris Benoit kill his family?

Over a three day period ending on June 24, 2007, WWE professional wrestler Chris Benoit killed his wife, Nancy Benoit, and then strangled his seven year old son and subsequently hanged himself. Autopsy results showed that Benoit first murdered his wife, Nancy. She was bound at the feet and wrists and died of asphyxiation sometime on Friday, Fayette County District Attorney Scott Ballard told a news conference. She was wrapped in a towel and some blood was found under her head but Ballard said there were no other signs of a struggle. The couple's son, who also died of asphyxia, was apparently killed as he lay in bed on Saturday morning, hours before Benoit hanged himself. Benoit left no suicide note but placed bibles alongside the bodies of his wife and son, as well as a bible on his weight lifting machine. a href="http://en.wikipedia.org/wiki/Chris_Benoit_double_murder_and_suicide" rel="nofollow"http://en.wikipedia.org/wiki/Chris_Benoi…/a
