On the morning of May 18th, 1927, Andrew Kehoe murdered his wife and set his farm on fire. Meanwhile, at the Bath Consolidated School, he rigged explosives to go off at about the same time. He then drove to the school, parked his truck out front and detonated a bomb in his truck killing himself as well as other people surrounding it. After it was all said and done, he killed 38 students and 6 adults, with the students ranging from 2nd grade to 6th grade. To this day, it remains the deadliest school massacre in United States history.
