Inmate executed in Oklahoma’s first lethal injection in six years

John Marion Grant, convicted of stabbing a prison cafeteria worker, was the first since a series of flawed executions in 2014 and 2015

Oklahoma has executed a man for the 1998 stabbing death of a prison cafeteria worker, the state's first lethal injection following a six-year moratorium, after the US supreme court on Thursday cleared the way for the execution to proceed.

John Marion Grant, 60, was declared dead at 4:21pm after being strapped to a gurney inside the execution chamber and given a lethal injection of three drugs.
