After Yearick, (i don't think it was crooks), got his rifle hit he rose up a little and looked/pointed toward the trees where the crowd was calling him out. Then, perhaps thinking he'd try the rifle again, he went back to the prone firing position and aimed at the stage. That is what happens between shots 9 and 10. It seems that one he takes aim again the counter sniper positioned 488 yards away on the West grandstand roof of the arena takes the kill shot.
