Andrew Philip Kehoe was an American mass murderer. Kehoe was a Michigan farmer who became disgruntled after losing an election to be the Bath Township Clerk. He murdered his wife and then detonated bombs at the Bath Consolidated School on May 18, 1927, resulting in the Bath School disaster in which 45 people were killed and 58 more people were injured. Kehoe killed himself near the school by detonating dynamite in his truck, killing himself and several other people and wounding more. He had earlier set off incendiary devices in his house and around his farm, destroying all the buildings. The event remains the deadliest act of mass murder at an American school.
