Ohio inmate Dennis McGuire appeared to gasp and convulse for roughly 10 minutes before he died Thursday by lethal injection using a new combination of drugs, reporters who witnessed it said.
McGuire was convicted in 1994 of the rape and murder of 22-year-old Joy Stewart, who was seven months pregnant. Her relatives were at Southern Ohio Correctional Facility in Lucasville to witness his death, according to tweets from television reporter Sheila Gray.
Columbus Dispatch reporter Alan Johnson said that the whole execution process took 24 minutes, and that McGuire appeared to be gasping for air for 10 to 13 minutes.
"He gasped deeply. It was kind of a rattling, guttural sound. There was kind of a snorting through his nose. A couple of times, he definitely appeared to be choking," WDTN quoted Johnson as saying.
The convicted murderer was pronounced dead at 10:53 a.m. ET.
The execution generated controversy because, like many states, Ohio has been forced to find new drug protocols after European-based manufacturers banned U.S. prisons from using their drugs in executions -- among them, Danish-based Lundbeck, which manufactures pentobarbital.
According to Ohio's corrections department, the state used a combination of the drugs midazolam, a sedative; and the painkiller hydromorphone.
Both the length of time it took for McGuire to die and his gasping are not typical for an execution, said Howard Nearman, an anesthesiologist at University Hospitals Case Medical Center in Cleveland.
"Why it took 24 minutes, I really can't tell you," he said. "It just makes you wonder -- what was given? What was the timing, and what were the doses?"
In an opinion piece written for CNN this week, a law professor noted that McGuire's attorneys argued he would "suffocate to death in agony and terror."
"The state disagrees. But the truth is that no one knows exactly how McGuire will die, how long it will take or what he will experience in the process," wrote Elisabeth A. Semel, clinic professor of law and director of the Death Penalty Clinic at U.C. Berkeley School of Law.
the new mixture of drugs that killed a man in Ohio took 15 minutes to end his life. the death penalty seems pretty cruel and unusual at this point.
he's not a great guy, he raped and killed a woman in 1989, but i'm not sure hte state should be inflicting that sort of peverse justice. keep him in jail. i don't want to be a part of killing someone, especially not in this way.
