Bath Massacre: America’s First School Bombing

Theories of the Third Kind explores the Bath Massacre of May 18, 1927—the deadliest school attack in American history and the nation's first school bombing. Hosts Aaron and Daniel-san delve into the life of Andrew Kehoe, a Michigan farmer who, after years of financial strain, personal loss, and resentment toward rising school taxes, meticulously planned a dual-phase attack. He first detonated explosives on his farm to distract emergency responders, then triggered a massive explosion at the Bath Consolidated School, killing 45 people—mostly children—before driving a car packed with explosives to the scene, where he died in a final blast. The episode examines Kehoe’s troubled past, including the death of his stepmother, his wife’s tuberculosis, and his growing paranoia, culminating in a calculated act of revenge. The hosts analyze multiple theories, from Kehoe acting alone to being framed or aided by others, and consider the ideological undercurrents of rural resistance to centralized education. Despite the trauma, the school reopened within months, underscoring the community’s resilience. The episode concludes with reflections on how societal neglect, lack of explosive regulation, and mental health crises converged in one of America’s most shocking tragedies.
