The Columbine High School massacre occurred on Tuesday, April 20, 1999, at Columbine High School in Columbine, an unincorporated area of Jefferson County, Colorado, United States, near Denver and Littleton. Two senior students, Eric Harris and Dylan Klebold, embarked on a massacre, killing 12 students and one teacher. They also injured 21 other students directly, and three people were injured while attempting to escape. The pair then committed suicide. It is the fourth-deadliest school massacre in United States history, after the 1927 Bath School disaster, 2007 Virginia Tech massacre and the 1966 University of Texas massacre, and the deadliest for an American high school.The massacre provoked debate regarding gun control laws, the availability of firearms in the United States, and gun violence involving youths. Much discussion also centered on the nature of high school cliques, subcultures, and bullying, as well as the role of violent movies and video games in American society. The shooting also resulted in an increased emphasis on school security, and a moral panic aimed at goth culture, social outcasts, the gun culture, the use of pharmaceutical anti-depressants by teenagers, violent films and music, teenage internet use,] and violent video games.
