The Columbine High School massacre was a school shooting and attempted bombing that occurred on April 20, 1999, at Columbine High School in Columbine, Colorado, United States. The perpetrators, twelfth grade ( senior) students Eric Harris and Dylan Klebold, murdered 12 students and one teacher. Ten students were killed in the school library, where the pair subsequently committed suicide. Twenty-one additional people were injured by gunshots, and gunfire was also exchanged with the police. Another three people were injured trying to escape. At the time, it was the deadliest secondary school shooting in U.S. history. The crime has inspired several copycats, including two deadlier shootings, and "Columbine" has become a byword for school shootings. In addition to the shootings, the attack involved several homemade bombs.
