Shot the students in rapid succession during the storming of the building...kids were lined up along the blackboard...
Perp had given a 10-second warning to cops, and then he started shooting in rapid succession - - - the cops began the assault upon getting the 10-second warning - - -
so before help arrived, he had time to nail 2x4's across every doorway, AND bind all the girls' feet, AND shoot them all?
too bad one of them teachers/aids couldn't have shot this creep before he had the chance to do all this.
