He was good until the burglar dropped his pickaxe and ran.
He first shot when the burglar had the pickax and was going towards him.
That may have been the fatal shot.
When he shot after the burglar was retreating, he may not have hit him.
He was good until he admitted to firing a few shots into the night after the pero dropped the pickaxe and ran.
Big question.... Was the bad guy shot in his front side or in the back. Also was he once or twice and is there a pick ax in the yard and is the shed damaged? Why is this murder?
