Ryan Harris, a 17-year-old student at Stevens High School, walked into his math classroom on September 11, 1991, armed with a sawed-off shotgun. He ordered the teacher to leave and held the rest of the class hostage for four hours, firing shots at the walls and making demands for pizza, cigarettes, and even a helicopter. Harris later admitted he was inspired by Stephen King's novel Rage, in which a misfit student kills a teacher and holds a class hostage
