I just read that about the valium. They were trying to say that the side affects could have caused him to kill those people. I believe most people could see through that. Most people know someone who takes, or has taken valium.
The News people are going to say anything that they can think up. He didn't become a homicidal maniac from taking valium. My gosh!!! It was a evil heart. Then the actions of a evil homicidal heart. How he got that way is a mystery. Hatred must have festered in his heart. BF
