Botched Execution of John Marion Grant

On October 28, 2021, Oklahoma attempted to execute John Marion Grant using lethal injection. The procedure became a documented example in the modern U.S. history of botched executions.

What happened

After midazolam was administered, witnesses reported repeated full-body convulsions and vomiting. The autopsy later documented pulmonary edema and other findings that became part of renewed scrutiny of Oklahoma’s three-drug protocol.

Result

The immediate result was that John Marion Grant died after convulsing and vomiting during Oklahoma’s return to executions. This is an important distinction in the broader history of execution failures: some botched procedures ultimately kill the prisoner after a prolonged or visibly problematic process, while others are abandoned and leave the prisoner alive.

Why the case is classified as botched

The Death Penalty Information Center’s historical compilation uses a research definition centered on breakdowns or departures from execution protocol that produce unanticipated problems, delays, possible unnecessary suffering, or gross operational incompetence. The John Marion Grant case fits that framework because the intended lethal injection process did not proceed in the controlled manner the state expected.

Historical context

The event page is kept separate from the person profile so later work can attach the correct prison, execution protocol, court litigation, officials, method history and state-level death-penalty context without overloading the biography.
