Shooter wore a black mask with a white skull face. He called his father while fleeing saying he'd been shot and might not make it. Not known at this time if the hero who shot him killed him or he died from a self-inflicted wound.
Considering there was someone shooting at him with a rifle, and he likely would not have shot himself with one, if he called his dad and was wounded while he was driving/talking on the phone, chances are the wound that he was talking about was not self-inflicted. He may have killed himself later.
IMHO, the MSM types will play down the armed citizen aspect to hype gun control.
