Hmmmm, two people dead at the same site and they apparently knew each other.  Someone walks up and single handed kills them one at a time?  Was the other person just standing still waiting for there turn to be killed?  How do you kill two people at the same time and then manage to walk away undetected?  Yeah, you're hoping a gun wasn't involved but I bet there was.  Oh, and let's forget about the other three people that were shot and killed and another two that are laid up in the hospital.  At least, we know, four out of the five APD investigations were gun related.
