the ballistics report should clear that up? Mattis the reporter described two shots - the first he said was after KR pulled his gun up and away from redshirt grabbing it. That could be the head graze that looks like a bullet wound? Mattis also said that he saw one shot go to ground. sparked? So guessing that’s when KB lowered the weapon back down? speculating.
Have read somewhere that KR fired 1 shot into the ground in front of redshirt and raised his weapon and fired 1 more shot. I speculate this round went thru redshirt’s hand, into his groin, and then shattered his hip. The wounds to his back and head came from another shooter, as he dropped in front of KR face down, so how did KR shoot him in the back?
