    Oklahoma inmate dies after execution is botched

    McALESTER, Okla. — A botched execution that used a new drug combination left an Oklahoma inmate writhing and clenching his teeth on the gurney Tuesday, leading prison officials to halt the proceedings before the inmate’s eventual death from a heart attack.

    Clayton Lockett, 38, was declared unconscious 10 minutes after the first of the state’s new three-drug lethal injection combination was administered. Three minutes later, though, he began breathing heavily, writhing, clenching his teeth, and straining to lift his head off the pillow.

    The blinds were eventually lowered to prevent those in the viewing gallery from watching what was happening in the death chamber, and the state’s top prison official eventually called a halt to the proceedings. Lockett died of a heart attack a short time later, the Department of Corrections said.


    ‘‘It was a horrible thing to witness. This was totally botched,’’ said Lockett’s lawyer, David Autry.

    The apparent failure of the execution could fuel more debate about the ability of states to administer lethal injections that meet the Constitution’s requirement they be a neither cruel nor unusual punishment. That question has drawn renewed attention from defense lawyers and death penalty opponents in recent months, as several states scrambled to find new sources of execution drugs because drugmakers that oppose capital punishment — many based in Europe — have stopped selling to prisons and corrections departments.

    Several states have gone to court to shield the identities of the new sources of their execution drugs. Missouri and Texas, like Oklahoma, have both refused to reveal their sources, but both of those states have since successfully carried out executions with their new supplies.

    Tuesday was the first time Oklahoma used the drug midazolam as the first element in its execution drug combination. Other states have used it before; Florida administers 500 milligrams of midazolam as part of its three-drug combination. Oklahoma used 100 milligrams of that drug.

    Governor Mary Fallin, a Republican, ordered a 14-day stay of execution for an inmate who was scheduled to die two hours after Lockett, Charles Warner. She also ordered the state’s Department of Corrections to conduct a ‘‘full review of Oklahoma’s execution procedures to determine what happened and why during this evening’s execution.’’


    Robert Patton, the department’s director, halted Lockett’s execution about 20 minutes after the first drug was administered. He later said there had been vein failure.

    The execution began at 6:23 p.m., when officials began administering the first drug. A doctor declared Lockett to be unconscious at 6:33 p.m. At 6:39 — three minutes after Lockett began writhing — a doctor lifted the sheet that was covering the inmate to examine the injection site. By that time, all three drugs had been administered.

    ‘‘There was some concern at that time that the drugs were not having that [desired] effect, and the doctor observed the line at that time and determined the line had blown,’’ Patton said at a news conference afterward, referring to Lockett’s vein rupturing.

    After an official lowered the blinds, Patton made a series of phone calls before calling a halt to the execution.

    Lockett was declared dead at 7:06 p.m.


    A four-time felon, Lockett was convicted of shooting 19-year-old Stephanie Neiman with a sawed-off shotgun and watching as two accomplices buried her alive in rural Kay County in 1999 after Neiman and a friend arrived at a home the men were robbing.

    Warner had been scheduled to be put to death two hours later in the same room and on the same gurney. The 46-year-old was convicted of raping and killing his roommate’s 11-month-old daughter in 1997.
