Columbine Shooting, 1999
On April 20, 1999, two students, (not named here) walked into Columbine High School in Columbine, Colorado, United States, a suburb outside of Denver, and murdered 12 students and one teacher, before the pair subsequently died by suicide. In an exchange of gunfire with police, and twenty-one additional people were injured by gunshots, three others injured trying to escape the school. At the time, it was the deadliest school shooting in U.S. history, but since, the crime has inspired several copycats and "Columbine" has become a byword for school shootings.
