On December 13, 1993, four employees were shot and killed and a fifth employee was seriously injured at a Chuck E. Cheese's restaurant in Aurora, Colorado. The perpetrator, 19-year-old Nathan Dunlap, a former employee of the restaurant, was frustrated about being fired from working at the restaurant five months prior to the shooting and sought revenge by committing the attack. He had also fled the scene of the shooting with stolen cash and restaurant items.
