Officials from the Ohio Department of Rehabilitation and Correction say after a review, convicted killer Dennis McGuire died in a “humane, constitutional way” in January.
The case made national headlines after McGuire was put to death with a combination of drugs that had never before been tried in the United States. During the execution, he appeared to gasp several times, and it took him more than 15 minutes to die. He opened and shut his mouth several times as his stomach rose and fell.
In a statement, Department of Rehabilitation and Correction spokeswoman JoEllen Smith said: "After the review, the Department remains confident that it conducted the execution in a humane, constitutional way and that the inmate was completely unconscious and felt no pain.”
McGuire's lawyers had tried to stop the execution, arguing that the method would put him at a substantial risk of "agony and terror" while straining to catch his breath.
McGuire was sentenced to die for the death of 22-year-old Joy Stewart in Preble County in western Ohio.
