from the kitchen, hidden so close to the killers he could hear them
reloading their guns.
The *two* gunmen began firing in the parking
lot, killing Rachel Scott with a bullet to the head. Danny Rohrbough was
the next to fall, just outside the entrance. From there they closed in on
the cafeteria where they threw pipe bombs as well as shot at fleeing
