Whether he was an up and coming drug dealer, or not, or had possession of an illegal firearm, he didn't deserve to be incarcerated for that many years if he didn't pull the trigger. I wonder if he had a relationship to the victim or a vendetta of some sort as well. There was mention it was over a dispute about a girl.
