Over a three-day period between June 22 and 24, 2007, Chris Benoit, a 40-year-old Canadian professional wrestler employed by World Wrestling Entertainment (WWE), murdered his wife Nancy and their seven-year-old son, Daniel, before hanging himself at their residence in Fayetteville, Georgia, United States. Autopsy results showed that Nancy was murdered first, having died of asphyxiation on the night of June 22.

Daniel, who also died of asphyxia, was killed as he was lying sedated in his bed on the morning of June 23. On the evening of June 24, Benoit killed himself in his weight room, when he used his lat pulldown machine to hang himself. He placed Bibles near the bodies of Nancy and Daniel. Since the tragedy, numerous explanations for Benoit's actions have been proposed, including severe chronic traumatic encephalopathy (CTE) and steroid and alcohol abuse, leading to a failing marriage and other personal problems. This led to numerous media accounts, and a federal investigation into steroid abuse in professional wrestling.
