That’s what I thought at first, because I saw the video of wounded people being dragged outside. But those are long drag marks, and they go around the piles of bodies. I would think someone would have been shot down before dragging a wounded friend that distance if it had happened during the live fire incident.
Who knows. It was very dark in there.
IIRC, at some point the savages left the auditorium and went in search of other victims
