dumb, the guy was probably already dead since he was shot in the head.
So basically, he is sentenced to life in prison for shooting a dead person.
First things first.
My personal view: Ersland is an idiot for chasing the guy after he left the pharmacy and Ersland is morally repugnant for returning, getting a second gun, and shooting the injured boy 5 more times. Speaking as a card-carrying member of the NRA and an owner of numerous firearms, Ersland deserves his conviction. He was irresponsible and allowed himself to get carried away, which is simply not permissible when dealing with firearms.
That said,
Legal evaluation: This is, of course, getting appealed, but the appeal isn't going anywhere. The jury verdict appears legally correct. The jury found that Parker was still alive after being shot in the head, and that Parker did not represent a threat after being shot, which are the critical findings of fact in this case. Unless there are other errors in the case, an appeals court isn't going to turn this one around. Appellate courts almost never overturn jury's findings of fact and there's only one ultimate legal conclusion based on the jury's finding that Parker was still alive but presenting no danger after the first shot.
