A condemned Ohio killer appeared to gasp several times during his prolonged execution with the first use of a never-tried lethal injection process never before tried in the U.S.
Death row inmate Dennis McGuire made several loud snorting or snoring sounds during the more than 15 minutes it appeared to take him to die.
It was one of the longest executions since Ohio resumed capital punishment in 1999.
McGuire's stomach rose and fell several times as he repeatedly opened and shut his mouth.
McGuire's adult children sobbed a few feet away in a witness room as they watched him die.
McGuire was sentenced to die for the death of 22-year-old Joy Stewart in Preble County in western Ohio.
