On April 20, 1999, two teenage gunmen killed 13 people in a
shooting spree at Columbine High School in Littleton,
Colorado, south of Denver.
At approximately 11:19 a.m., Dylan Klebold, 17, and Eric Harris,
18, dressed in trench coats, began shooting students outside
the school before moving inside to continue their rampage.
By 11:35 a.m., Klebold and Harris had killed 12 fellow students
and a teacher and wounded another 23 people. Shortly after
noon, the two teens turned their guns on themselves and died
by suicide.
The crime prompted a national debate on gun control and
school safety, as well as a major investigation to determine
what motivated the teen gunmen.
In the days immediately following the shootings, it was
speculated that Klebold and Harris purposely chose jocks,
minorities and Christians as their victims.
