There's footage that is alleged to be the shooter, limp, being hauled away by troopers. Seems like fire was indeed returned, much to the shooter's detriment.

EDIT: That was not the shooter. That was likely either the dead or critically wounded crowd member. Shooter was a sniper on a roof, apparently hundreds of yards away. Still killed though, by all accounts.
