True. But a slug ain’t a bullet and one does not “spray” an area with slugs...unless he had a serious semi-auto shotgun, which is doubtful. If it were slugs he fired, there’s a good chance he’d have never hit the kid. But, all supposition. Including the supposition that the writer could use some schooling in ordnance terminology.
But WOULD probably kill his girlfriend back in the house as well as the neighbor in HIS house.
