A new CBC documentary says Canadian wrestling star Chris Benoitís brain resembled that of an 85-year-old man with dementia when he killed himself and his family last summer.
After Benoit and his family were found dead in their Atlanta home in June, some commentators speculated Benoit may have killed his family during an episode of steroid-induced rage.
But doctors interviewed by the CBC say Benoitís brain was so damaged from repeated concussions that he couldnít be held responsible for his actions.
The findings stem from research first conducted on former NFL players like Andre Waters and Terry Long, who both committed suicide.
The Fifth Estate documentary, which airs Wednesday, probes the circumstances surrounding the premature death of Benoit and dozens of other pro wrestlers.
Benoit, who was born in Montreal and grew up in Edmonton, became World Wrestling Entertainmentís world champion in 2004.
