Wyoming executed 24 persons between 1884 and 1965. Of these, 7 were executed before statehood in 1890; 17 after. Until 1937 hanging was the only used method. In the 1930s, the gas chamber was introduced. Today, lethal injection is the only allowed form of execution.
After the 1972 finding by the US Supreme Court that several states’ death penalty statutes were unconstitutional, Wyoming reinstated its death penalty with a new statute in 1977. Since then one person has been executed, in 1992. One person remains on Wyoming’s death row.
