Death Penalty Information
The current death penalty law was enacted in 1977 by the Oklahoma Legislature. The method to carry out the execution is by lethal injection. 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 196 men and three women between 1915 and 2022 at the Oklahoma State Penitentiary. Eighty-two were executed by electrocution, one by hanging (a federal prisoner) and 116 by lethal injection. The last execution by electrocution took place in 1966. Charles Troy Coleman was the first Oklahoma inmate executed by lethal injection on September 10, 1990. Coleman was convicted in 1979 of Murder-First Degree in Muskogee County.
