Obviously he hanged himself and the coroner blasted him with a shotgun to check if he was dead. Duh.
In a panic, he called 911 and explained the situation:
FRIEND: Oh, my God. My friend and I were hunting, I tripped over a log and my gun went off! He got hit in the back, and I think he is dead, he isn't responding to me or even moving.
911 DESK: Okay. I need you to calm down. First, we need to make sure he is really dead and not just unconscious. I need you to do that for me. Can you do that?
FRIEND: Oh? Uh, okay, hang on a minute. I'll make sure.
911 DESK: (Listening...abrupt sound of gunshot over the phone)
FRIEND: Okay. He is really dead. What do I do next?
No, he accidentally shot himself on the chest with a shotgun, then tried to make sure he wouldn’t bleed out by hanging himself.
