ROBERT SIEGEL, HOST:
There were 35 executions in the U.S. last year - that's the lowest in two decades. Death penalty states are having increasing difficulty obtaining the drugs they've used in the past. Pharmaceutical companies don't want to be associated with killing people. And states have been seeking new formulas using untested doses and are trying to find new compounding pharmacies to make their execution drugs. The results in 2014 included four executions that didn't go as planned. NPR's Wade Goodwyn takes a look at one of those cases and the latest questions in the debate over the death penalty.
WADE GOODWYN, BYLINE: Michael Kiefer is a veteran reporter for The Arizona Republic, who, over the years, has been witness to five Arizona executions. Last July, Kiefer was observing the execution of double murderer Joseph Wood. For Wood's execution, the Arizona Department of Corrections was using a different drug formula for the first time.
MICHAEL KIEFER: We were escorted in. Everything seemed to go smoothly. You watch the catheters being inserted. Joseph Wood closed his eyes, his head went back. It looked like executions I'd seen before using thiopental and pentobarbital.
GOODWYN: With those drugs, Kiefer says it normally took five to 10 minutes for a condemned man to die, but at the six minute mark...
KIEFER: Suddenly, he opened his mouth. I mean, his mouth sort of made this funny round shape. And it was just - you could see this expulsion of air. And we all jumped, you know? This was - this was something different.
GOODWYN: Wood had begun fighting for his life, taking large intermittent breaths.
KIEFER: And then there was another and then another and then it just kept going. I started putting little hash marks on my pad, my notepad, to see how many times he did this - 640 times.
GOODWYN: The executioner eventually came out, turned on the death chamber microphone and tried to reassure everyone that Wood was asleep and it was OK. But Kiefer says the sounds emanating from the condemned man that were suddenly brutally audible behind the executioner's voice only added another layer to everyone's distress. An hour passed.
KIEFER: We looked at each other; you could see the alarm on the faces of the prison personnel. Nobody said anything. I turned to the reporter next to me and said I don't think he's going to die. I was wondering if Wood was going to open his eyes again.
GOODWYN: Arizona's new drug formula - 50 milligrams of midazolam, a sedative, and 50 milligrams of hydromorphone, a narcotic - was supposed to be a lethal dose. Obviously, it wasn't. So the executioner gave Wood a second dose and then a third - four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen. And then, mercifully, on the 15th dose, Wood died. It had taken nearly two hours.
MAURIE LEVIN: A mess is a good way to put it.
GOODWYN: Maurie Levin is a capital defense attorney in Texas who's been doing most of the lethal injection litigation in the state that is the runaway death penalty leader. For both moral and public relations reasons, pharmaceutical companies no longer want any association with the death penalty process. Their drugs are to be used for healing only. Levin says that has forced death penalty states to search for new drug combinations and new sources - compounding pharmacies.
LEVIN: Texas - TDCJ - the prison, went to a pharmacy in Houston. They wrote them a letter, it was only discovered later, that said we promise you that we will keep this on the down-low.
GOODWYN: Down-low was actually the phrase used. Just like the big pharmaceutical companies, compounding pharmacies don't want to be associated with executions either. So when the name of the pharmacy was disclosed in a court proceeding, the Houston compounding pharmacy was furious, embarrassed and quit.
LEVIN: And the pharmacy asked for their drugs back, and the prison refused to give them back.
GOODWYN: The outing of compounding pharmacies has become a serious threat to death penalty states' drug supplies. Like several other death penalty states, Texas argues the identity of its drug suppliers should be a state secret, not even judges should be able to find out. Jason Clark is a spokesman for the Texas Department of Criminal Justice.
JASON CLARK: We've said before that disclosing the identity of the pharmacy would result in harassment of the business and it's going to raise serious safety concerns for the business and its employees.
GOODWYN: But last month a Texas judge rejected the state's arguments, ruling the name of the compounding pharmacy is public information. Texas is appealing. This is the new front in the legal war over the death penalty. Aclean and painless death by injection has played a major role in preserving capital punishment in America. If that becomes a problem, it could complicate the institutions long-term survival. Wade Goodwyn, NPR News, Dallas.
