If you're really interested in knowing exactly what happened, look up the testimony of the medical examiner. That will tell you the path of the bullets.
Without seeing the testimony, my bet is that these guys achieved their target and, as I said, just kept pulling the trigger until it went "click", while following their target as most are trained to do. They would hold their sight picture as the guy collapsed, and the last few bullets would probably go into the back of the head and the back as the goblin hit the floor.
Alternatively, if the man spun as he was hit (and a near-winger in either shoulder would spin him), the next round or two would graze his back or maybe even penetrate.
And yes, I've read a lot of physician and ME reports from shootings. Sadly, that is one of the less appetizing parts of my job.
And since our judgments don't matter, I think we're free to speculate as much as we like. This isn't a court of law.
