Chris Benoit: Oddly enough, met him at a Brian Pillman Tribute show in Cincinnatti. Was real quiet and seemed like he could easily snap (Which he obviously did when he killed his wife and kid).
If you read the Wiki Page on him
"After the double-murder suicide, former wrestler
Christopher Nowinski contacted Michael Benoit, father of Chris Benoit, suggesting that years of
trauma to his son's brain may have led to his actions. Tests were conducted on Benoit's brain by Julian Bailes, the head of neurosurgery at
West Virginia University, and results showed that "Benoit's brain was so severely damaged it resembled the brain of an 85-year-old Alzheimer's patient."
[108] He was reported to have had an advanced form of dementia, similar to the brains of four retired NFL players who had suffered multiple concussions, sank into depression, and harmed themselves or others. Bailes and his colleagues concluded that repeated concussions can lead to
dementia, which can contribute to severe behavioral problems.
[109] Benoit's father suggests that brain damage may have been the leading cause of the crime.
[110] He also confirmed that his son was quietly
cremated, but what was done with the ashes is not public knowledge.
