The worst mass-murder in a school in American history did not involve guns or shooters; it involved a bomb in an elementary school.
It didn't take place in Connecticut; it took place in the rural community of Bath, Michigan.
The perpetrator wasn't a young man - he was 55 years old.
And the attack did not occur this year or last year - or even this decade.
The year was 1927.
In an unspeakably horrible crime, 55-year-old Andrew Kehoe killed his wife, set his farm on fire and then set off 500 pounds of explosives in a consolidated elementary school.
The blast killed 38 children aged 7 to 14, two teachers and four others as well as the killer himself.
The explosions would have killed more, but 500 pounds of dynamite in another wing of the school failed to detonate.
