Bath, Michigan: The Bomb Beneath the Children. The true crime history of the Bath School Disaster begins with an almost impossible fact: for months, children attended class directly above explosives hidden beneath their school.

On May 18, 1927, the small farming community of Bath Township, Michigan became the site of the deadliest mass murder at a school in American history. Nearly a century later, the Bath School Disaster remains one of America’s most disturbing pieces of forgotten history.

But this story did not begin with an explosion.

It began with a town trying to build something better.

In the 1920s, Bath was a rural community where children were scattered across small one-room schoolhouses. Residents voted to consolidate those schools and build a modern school that could give local children opportunities their parents never had.

One school. One community. One symbol of progress.

Then a trusted member of the school board began quietly hiding explosives underneath it.

Andrew Philip Kehoe was not a mysterious outsider. He was a local farmer, taxpayer, school board member, and school board treasurer. He had access to the building. He understood machinery and electrical systems. When people saw him working inside the school, they had little reason to suspect what he was actually doing.

For months, while children learned, laughed, passed notes, and waited for summer, Kehoe continued preparing the building for destruction.

And on the morning of May 18, 1927, his plan began.

Inside This Mystery:

• The dark history behind the Bath Consolidated School

This is Part 1 of the Yore Town investigation into the Bath School Disaster. We uncover how Bath built the school, who Andrew Kehoe was, how he gained the trust and access needed to move through the building, and how the children of Bath unknowingly spent months sitting above a massive cache of explosives.

Then May 18, 1927 arrived.

The farm began to burn.

The school exploded.

And when the man responsible drove into the chaos, the attack still was not over.

Every town has a past. Yore Town uncovers the real stories, forgotten crimes, and local mysteries that time tried to bury.
