Grant, 60, was a convicted murderer and was known as the first inmate since 2015 to be sentenced to death by lethal injection in Oklahoma.
JOHN Grant made headlines back in 1998 after he was convicted of murdering a prison guard.
The decision came after both Grant and Jones challenged the state's lethal injection protocol and refused to choose another form of execution, citing religious reasons, claiming it would be considered "suicide" to choose.
The pause came after an inmate in 2015 was executed using the wrong dugs and another inmate, Clayton Lockett, struggled on a gurney in what was called a botched execution using their three-drug lethal injection combination the year prior.
