Hugh Pickens DOT Com writes: CNN reports that Ohio inmate Dennis McGuire appeared to gasp and convulse for roughly 10 minutes before he finally died during his execution by lethal injection using a new combination of drugs after European-based manufacturers banned U.S. prisons from using their drugs in executions — among them, Danish-based Lundbeck, which manufactures pentobarbital. The state used a combination of the drugs midazolam, a sedative, and the painkiller hydromorphone, the state corrections department told CNN. In an opinion piece written for CNN earlier 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. According to a pool report from journalists who witnessed the execution, the whole process took more than 15 minutes, during which McGuire made "several loud snorting or snoring sounds." Allen Bohnert, a public defender who lead McGuire’s appeal to stop his execution in federal court on the grounds that the drugs would cause undue agony and terror, called the execution process a “failed experiment” and said his office will look into what happened. “The people of the state of Ohio should be appalled by what took place here today in their name."
