Current practices

Capital crimes

First-degree murder is the only capital crime in Wyoming.[1] There are 11 aggravating factors.[2]

A person convicted of first-degree murder may be sentenced instead to life in prison without parole.[1]

As in any other state, people who are under 18 at the time of commission of the capital crime [3] or mentally retarded[4] are constitutionally precluded from being executed.

Death row and clemency process

Death row for men is located at the Wyoming State Penitentiary in Rawlins, and the location for women is at the Wyoming Women's Center in Lusk. As of February 2015, no one is awaiting execution.[5]

Only the Governor of Wyoming may grant commutation of a death sentence. Since 1977, no commutation has been granted.[6]

Method of executions

Lethal injection is the sole method of execution. Gas chamber, however, is a backup method if lethal injection should ever be found unconstitutional.[7]

History and list of executions

Wyoming has never executed a woman.[8]
