According to court records, Vang allegedly shot several of Sundays victims in the back.
Hard to shoot someone in the back when they are in front of you. You would have to circle behind them. Add in the fact that he turned his jacket from orange to cameo and he was hunting.
I knew one or more were shot in the back, I thought they were fleeing.
And from what I read, he had started to walk away when he turned and started firing. If any turned and ran they would have got it in the back. I also read that at least two were shot when on their ATV's(?) (the woman and the teen?). I don't know if they were shot upon arrival or if they tried to get away after arriving.
