Obviously wasn't there and I have no way of knowing. As far as data goes I know that we teach that you can expect the average man to be able to close a distance of 11 feet before a trained person can draw his weapon and fire. I know the officers weapon was drawn but it gives you a time space estimate. With the number of hits and their placement (all on the subjects right so the left for the shooter) I think he probably had a 50-75% hit ratio. 35 feet equals roughly 10 meters which would be a pretty easy shot on a man that size, without the obvious situational difficulties. So if I had to call it I would say 10-12 shots. I think he probably had to start shooting at close to the 35 feet or potentially beyond; as a majority of the wounds were superficial it is possible that the subject was able to keep moving forward rapidly after being hit.
