On May 16, 1986, David and Doris Young entered Cokeville Elementary School with a gasoline bomb, a variety of rifles and handguns, David's philosophical writings and demands for $300 million in ransom. They held 154 students, teachers and staff hostage for three hours before Doris accidentally set off the bomb.

Many students were burned or suffered smoke inhalation, and one teacher was shot, but they all survived.
