Yes, well written story. Apparently, double-tapped him at the very first. It is VERY apparent to me that as the red car backs up to get away, she shot him again.
Round #2 occurred prior to the red cover car moving and was fired about 1/2 second after the first round.
When the cover car moves, what you’re seeing I believe is her motioning with the muzzle, telling the suspect to roll over, get on his stomach, which he complied.
Then again, you could be right...That would make #3.
