When William Happ, convicted of killing a 21-year-old woman in 1986, was executed by lethal injection in Florida last month, the state used a new combination of drugs. It took 14 minutes for him to die—twice as long as usual. Happ appeared to remain conscious longer than usual and was moving after he was unconscious. “This is somewhat of an experiment on a living human being,” said Richard Dieter, executive director of the Death Penalty Information Center, speculating that Happ could have been in severe pain and unable to express it. The state used midazolam hydrochloride as the initial drug of three rather than the barbiturate pentobarbital. The manufacturer of pentobarbital has banned its use for future executions (Daily Mail, October 15).
