Two backpacks filled with pipe bombs, aerosol canisters, and small propane bombs were also placed in a field about south of CHS, and south of the fire station. Set to detonate at 11:14 a.m., the bombs were intended as a diversion to draw firefighters and emergency personnel away from the school. Only the pipe bombs and one of the aerosol canisters detonated, causing a small fire, which was quickly extinguished by the fire department. It went off when moved. Bomb technicians immediately examined the bombs and relayed to police at the school the possibility of devices with motion activators.
