Ok so that link said that the guys had no intentions of killing anyone or whatever and they didnt think he was home. I read this
Police said that Garcia and Taylor were awakened by noise in the living room, and that Taylor got up and locked the bedroom door. The door was kicked in and two shots were fired, one striking Taylor in the leg.
Ok so you aren't a killer, but this event happened? If you heard the dude in the bedroom and realized he was home you could have ran the hell out of there. There was no need to kill him he had already locked himself in the bedroom so they could have escaped. BS they are killers plain and simple and it probably wasn't their first time. They were just lucky to get caught this time.
