The audio analysis here makes a convincing case that after Crooks initial 3 spaced shots and the next burst of five, the 9th shot came from a Beaver County SWAT member. All he says is it “distracted” Crooks but maybe it was a hit - to the leg? Agree the evidence is sketchy but the 9th shot sounds different than the 10th, which is the SS Hercules headshot that killed him, and while it’s possible that a skilled sniper missed at this range, it seems more logical that he would have hit Crooks, even if not fatally.
