Seems this guy had gone outside, and apparently threatened a neighbor.
According to the initial investigation, the [dead guy] was at his girlfriend's house when he grabbed a billiards stick and started hitting things in the residence.They are leaving open the option of charging the homeowner, but if this description is accurate, it sounds like self-defense to me. Being attacked with (or without) a pool cue sounds like a threat of grave bodily injury.
He went outside and continued to cause a disturbance, according to Mesa police.
The neighbor went outside and was confronted by the man with the stick.
That's when police believe the victim started running toward the homeowner.
The homeowner was on his own property and armed with a gun. The homeowner shot the man as he came toward him, according to Mesa police.
Self-defense is a human right.
