Columbine High School massacre: 18-year-old Eric Harris and 17-year-old Dylan Klebold, students at Columbine High School, killed twelve students and one teacher; after killing two students in the schoolyard and fatally wounding a teacher in the hallway, they killed the rest of their victims in the school library. They also wounded twenty-one additional people (twelve in the library and nine elsewhere), started fires and engaged in several gunfights with police, though no one was hit in these exchanges. Another three people injured themselves attempting to escape the school. The pair committed suicide at the end of the massacre.
