The execution date has been set for a man convicted of murdering a kitchen worker in the prison where he was serving a sentence for armed robbery.
John Marion Grant, 53, is scheduled to be put to death by lethal injection Dec. 4.
Grant was serving a 35-year sentence for the robbery out of Oklahoma County at the Dick Conner Correctional Center in Hominy. He was imprisoned in 1980, and had prior convictions in Oklahoma and Cleveland counties for burglary and robbery.
On Nov. 13, 1998, Grant fatally stabbed 58-year-old Gay Carter with a sharpened screwdriver in the prison kitchen. Grant then stabbed himself in the chest with the weapon several times.
Grant was convicted on a first-degree murder charge and sentenced to death in 2000.
The U.S. Supreme Court ordered a review of his case regarding his troubled childhood, but his appeals were denied. Grant was first imprisoned at age 17, and after being paroled briefly, has spent his life since age 19 in prison.
Grant’s execution will be the third in the state following the botched lethal injection of Clayton Lockett. Charles Warner is scheduled to be put to death Nov. 13 and Richard Eugene Glossip’s execution is set for Nov. 20.
