OKay so I got a better scoop from a kid in one of my classes that works security there.
He said the group of kids were starting to fight and one pulled the gun and tried to shoot, apparantly the target punched him causing the kid to jerk and shoot the ceiling, he said he tried to shoot again but the gun jammed (apparantly a semi-auto, he said automatic but he probably didn't know any better) at that point mall security and 3 off-duty LEOs started chasing the group. the kid with the gun tossed it, and then the suspects in the picture from the news were tackled and arrested on the spot.
the picture was taken by an employee at the T-Mobile Kiosk on the second floor.
All went down pretty quick and there were no injuries.
So let me get this straight, the gun didn't drop to the floor and fire itself? hmmm
