ABC News is confirming that tests conducted by Julian Bailes of the Sports Legacy Institute show that Chris Benoit's brain was severely damaged at the time he murdered his wife and son before taking his own life. According to the tests his brain resembled that of an 85-year-old Alzheimer's patient. Bailes said that the damage was the result of lifetime chronic concussions and head trauma.
Chris Benoit was famous for his flying headbutt, which is a lot of stress on the brain each time the maneuver is pulled off. While nothing can justify his actions, this at least helps the coping process.
