From this one photo, I proved that this was an inside job. That body was at lest 6 feet from the apex, so he didn't have line of sight. No blood trail marks coming down from the sloped roof, so he died where he was shot. The blood trail indicates that he was shot from behind with a small caliber weapon as sniper rifle from 400 yards would have taken his head off. We need to ask these questions. There are many that participated in this without a doubt.
