Botched Execution of Dennis McGuire

On January 16, 2014, Ohio attempted to execute Dennis McGuire using lethal injection. The procedure became a documented example in the modern U.S. history of botched executions.

What happened

Ohio used a then-unprecedented combination of midazolam and hydromorphone. Witnesses described approximately 25 minutes of labored breathing and other visible reactions before McGuire was declared dead.

Result

The immediate result was that Dennis McGuire died after a prolonged execution marked by gasping, snorting and choking sounds. 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 Dennis McGuire 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.
