The Bath School disaster is the name given to the bombing that occurred in Bath Township, Michigan, USA, on May 18, 1927, which killed 38 primary schoolchildren and 7 adults, and injured at least 58 people. Most of the victims were children in the second to sixth grades (7–12 years of age) attending the Bath Consolidated School. Their deaths constitute the deadliest act of mass murder in a school in U.S. history. The perpetrator was school board member Andrew Kehoe, who was upset by a property tax that had been levied to fund the construction of the school building. He blamed the additional tax for financial hardships which led to foreclosure proceedings against his farm. These events apparently provoked Kehoe to plan his attack.
On the morning of May 18, Kehoe first killed his wife, then set his farm buildings afire. As fire fighters arrived at the farm, an explosion devastated the north wing of the school building, killing many of the people inside. Kehoe used a detonator to ignite dynamite and hundreds of pounds of pyrotol which he had secretly planted inside the school over the course of many months. As rescuers started gathering at the school, Kehoe drove up, stopped, and detonated a bomb inside his shrapnel-filled vehicle, killing himself and the school superintendent, and killing and injuring several others. During rescue efforts searchers discovered an additional 500 pounds (230 kg) of unexploded dynamite and pyrotol planted throughout the basement of the school's south wing.
