1993 Aurora, Colorado shooting

On December 14, 1993, four employees were shot and killed, and a fifth employee was critically injured at a Chuck E. Cheese's (formerly a ShowBiz Pizza Place) restaurant in Aurora, Colorado, United States. The perpetrator, 19-year-old Nathan Jerard Dunlap, a former employee of the restaurant, was frustrated about being fired five months prior to the shooting and sought revenge by committing the attack. He fled the scene of the shooting with stolen money and restaurant items. At the time, the Chuck E. Cheese massacre was the deadliest mass shooting in Colorado, before being surpassed by the Columbine High School massacre in 1999.

Dunlap was found guilty of four counts of first-degree murder, attempted murder, and other charges, and was sentenced to death by lethal injection on May 17, 1996. A judge initially set an execution date for him in August 2013, but Colorado GovernorJohn Hickenlooper signed a temporary reprieve that postponed Dunlap's execution date.

Dunlap's death sentence was commuted to life in prison without parole in 2020 after Colorado abolished the death penalty.
