Columbine Shootings

The Columbine High School massacre was a school shooting which occurred on April 20, 1999, at Columbine High School in Columbine, an unincorporated area of Jefferson County in the State of Colorado. In addition to shootings, the complex and highly planned attack involved a fire bomb to divert firefighters, propane tanks converted to bombs placed in the cafeteria, 99 explosive devices, and bombs rigged in cars. Two senior students, Eric Harris and Dylan Klebold, murdered a total of 12 students and one teacher. They injured 24 additional students, with three other people being injured while attempting to escape the school. The pair then committed suicide.
