Well at least in this way, the possible killings of innocent people will stop. This shows that he had serious mental problems.
He took the cowards way out. I wish the cops caught this guy before he killed himself. It would be justice to have him sit in a cell for the rest of his life.
Yes, he's a coward. He escaped from just punishment to ease his suffering. I hope he got into hell and there he will atone for his sins.
