On May 18, 1927, Kehoe then set off almost simultaneous explosions at his farmstead and at the Bath Consolidated School. His devices destroyed the farm's buildings and ripped through the north wing of the Bath Consolidated School building. As rescuers began working at the school, Kehoe drove up to the schoolyard and detonated dynamite inside his shrapnel-filled truck. The truck explosion killed Kehoe plus four other people, and also injured bystanders. During the rescue and recovery efforts, searchers discovered an additional 500 pounds (230 kg) of unexploded dynamite and pyrotol in the south wing of the school that had been set to go off at the same time as the initial explosions in the north wing; Kehoe had apparently intended to destroy the entire school and kill everyone in it.
