The original death penalty law in Oklahoma called for executions to be carried out by electrocution. In 1972 the U.S. Supreme Court ruled unconstitutional the death penalty as it was then administered. Oklahoma has executed a total of 124 men and 2 woman between 1915 and 2001 at the Oklahoma State Penitentiary. The last execution by electrocution took place in 1966.
