In theory, Wilson fires the first six shots to Browns right arm as it's curled in front of him. Wilson is right handed, Brown is left handed. Brown is either grabbing Wilson with his right arm, or defending with his right arm in front of him in this position. Either way, two grazing shots hit the thumb and right arm of Brown. Disengage after the first shots where Wilson either exits the vehicle or continues to fire from inside. Brown either disengaged, and is now running towards Wilson, or did not move away and the follow-up shots happen. Two to the chest as he's turning his body to the left to get away, exposing the right side of his body. He leans forward or drops after being hit in the chest, where two shots follow to his head on the right side. He then runs away (leaving his shoes well behind his body) where he collapses and dies.
