Actually I don't know that it was the steroids but I'll bet that it was. How many years do you think that guy was on the anabolics? He was 40 years old and according to Wikipedia [

Crazy enough to bind your wife at the wrists and ankles then strangle her? Crazy enough to put a pillow over your 7 year old son's face and smother him? Crazy enough to hang yourself by the cord of your weight machine? I guess so.
