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.
