ABSTRACT
At about 11:20 a.m. on Tuesday April 20, 1999, two boys named Eric Harris and Dylan Klebold armed themselves with guns and homemade bombs. The boys entered Columbine High School in Littleton, Colorado. In the next few minutes, they killed 13 people and wounded at least 24 others, before turning their weapons on themselves. Later, it was discovered that these boys were fond of violent video games.
