I thought Awesome hunged himself due to the situation with his family, specifically his wife divorcing him?
That's a normal part of the cycle of concussion related suicides. The person normally starts acting bizarrely and erratically, and that causes their spouse or family members to pull away from the person. When that happens it drives the already depressed person further into their depression, and that's often when they commit suicide. I don't think Awesome's brain was ever studied, but if it was it probably would have shown that he was suffering from CTE
