The worst school massacre in US History:
Bath School disaster - Wikipedia, the free encyclopedia

The Bath School disaster is the name given to three bombings in Bath Township, Michigan, on May 18, 1927, which killed 38 elementary school children, two teachers, four other adults and the bomber himself; at least 58 people were injured. Most of the victims were children in the second to sixth grades (7–11 years of age) attending the Bath Consolidated School. Their deaths constitute the deadliest mass murder in a school in U.S. history and the third-deadliest non-military massacre in U.S. history, behind 9/11 and the Oklahoma City bombing.

The bomber was school board treasurer Andrew Kehoe, 55, who died in a car bomb he set off after he drove up to the school as the crowd gathered to rescue survivors from the burning school.

 Apparently, he had a second bomb which  failed.  He probably would have upped the death toll to 200 or so if it had gone off.

Good thing it happened before the advent of the 24-hour News Cycle...
