Descrição:

Shortly after 11:14 AM the gunmen, dressed in black leather dusters (trenchcoats) and wearing wraparound sunglasses, carried two duffle bags into the school's cafeteria, each containing a 20-pound (9 kg) propane bomb set to go off at 11:17 AM -- during "A" Lunch, when the cafeteria was the most crowded, according to Eric's notes. Just moments before their entry a janitor turned off the cafeteria surveillance cameras to rewind the tape they recorded on, missing the act of the bags being left on the floor beside two tables. They could be seen clearly on the tape when it resumed recording 11:22 AM.
