There have been numerous shootings in Colorado, United States.


In the age of mass media, three Colorado massacres in the Denver metropolitan area made significant impacts on the national consciousness: the Columbine High School massacre in 1999, which resulted in 15 deaths (including the post-massacre suicides by the two perpetrators); the Aurora shooting in 2012, which resulted in 12 deaths; and the 2021 Boulder shooting, which resulted in 10 deaths.[1]

1993 Aurora, Colorado shooting Aurora December 14, 1993 4 Nathan Dunlap, 18, who was fired from a Chuck E. Cheese's restaurant as a cook, opened fire, killing four employees and wounding another. He was convicted of first-degree murder and attempted murder charges and was sentenced to death.[2] In 2013, then-Colorado Governor John Hickenlooper indefinitely delayed Dunlap’s execution.[3] Although Hickenlooper was expected to order a clemency in his death penalty before his term ended in early 2019 but took no such action.[4] <ref. He was succeeded by Governor Jared Polis, who commuted Dunlap's sentence to life imprisonment. He said he conferred with the families of Dunlap's victims, personally felt that Dunlap's crimes were "despicable," but took the action as being consistent with Colorado's prior repeal of the death penalty in cases of new crimes.[5]
