John Grant
John Grant was executed by the state of Oklahoma at the Oklahoma State Penitentiary on October 28, 2021, the first execution in the state after a long pause. Corrections officials said it went off without complication, while media witnesses said he convulsed and regurgitated. A medical examiner's report found that he aspirated on his own vomit, and an autopsy recorded lungs weighing 1,390 grams and bleeding of the tongue. Experts for death-row prisoners said these findings show he suffered severe pain from pulmonary edema during the execution, a conclusion prosecutors dispute.
Cause of death, as reported: Executed by the state. Media witnesses said he convulsed and regurgitated, and experts for death-row prisoners said the autopsy shows severe pain from pulmonary edema during the execution, while prosecutors dispute that conclusion.
Reported by: Oklahoma Department of Corrections (the agency that held him); medical examiner or coroner; media witnesses; experts for death-row prisoners (advocates).
