The state of Oklahoma re-executed a prisoner after seven years.

African-American John Marion Grant was sentenced to death in 1998 for the murder of a female prison worker in which he was serving his sentence.

The state of Oklahoma (southern United States) executed this Thursday John Marion Grant, a prisoner sentenced to death for murdering a prison worker in 1998, where he was serving a long sentence for several robberies.

Oklahoma, one of the highest-executions and death-row states in the country, had not killed a prisoner since January 2015, almost seven years ago, after fiascos forced a stay in several of its executions.

According to the Oklahoma Department, Grant, a 60-year-old African-American man, was pronounced dead at 4:21 p.m. local time (21:16 GMT) after receiving a lethal cocktail of drugs at the Oklahoma State Penitentiary in McAlester Corrections.

According to witnesses testifying to the execution, Grant vomited and had various seizures after being given the first of three cocktails, the controversial sedative midazolam.

Grant was serving a 130-year sentence for several armed robberies when he killed Guy Carter, an employee of the prison cafeteria, where he also worked.

Witnesses testified that Grant took Carter to a closet used for storing cleaning supplies and stabbed him 16 times with a homemade knife.

The inmate was sentenced to death in 1999, a year later.

After almost seven years without executions, legal litigation, and trying to build a lethal chamber with nitrogen gas, Oklahoma returned Thursday to kill a prisoner with the same method - lethal injection - and drugs that forced the pause.

One execution in January 2015 with the wrong drugs was the last straw. In another, months earlier, inmate Clayton Lockett lay dying on the stretcher for three-quarters of an hour, and his case went around the world.

Grant's was the first of seven executions scheduled in Oklahoma between Thursday and March 2022.

Grant is the ninth inmate to be executed this year in the United States. Since the Supreme Court restored the death penalty in 1976, 1,538 inmates have been executed in the country, 113 of them in Oklahoma United states.
