Keith Kimmel is the the guy, yes.
He wasn't a stupid man.
He definitely should have used his energy toward something more "productive" or beneficial.
If you want to read anything about his death, google "Keith Kimmel dead".
While he wasn't stupid, I will tell you that he was not a good person. I have had personal dealings with him.
If anyone does decide to look into what occured, my opinion is that he died of a drug overdose, or a combination of drugs/alcohol. He was at his "low" when I last spoke to him. I may sound like an a-hole saying this, but good riddance.
