I didn’t realize there was more then one. I had heard that a teacher was firing at him and a student was handing the teacher ammo.
Many people who ran home, got their guns and came back to keep the perp's head down long enough for someone to go up and kill him. Who knows how many lives they saved, as they prevented him from shooting anybody else for quite a while.
Of course, today they'd all be arrested for bringing a weapon on campus, discharging a firearm within city limits, and violating noise ordinances.
Maybe it was just gun class. A blank went off.
