Oklahoma inmate Clayton Lockett was tasered by guards, and cut his own arm, in the hours just before his ultimately botched execution at the hands of the state's Department of Corrections. Lockett died, possibly from a heart attack, after officials called off his execution after the drugs had been administered. Lockett was to be one of two inmates killed in the state last Tuesday, despite a number of questions over the sourcing, and constitutionality, of the state's untested lethal injection cocktail.
The full timeline, via the Guardian, details Lockett's last minutes, and provides a little more information on what happened in the execution chamber. Because officials couldn't find a vein on Lockett suitable for the procedure, the phlebotomist tasked with making sure the IVs are inserted properly ended up using a vein in his groin for the procedure. The first drugs entered his body at 6:23 p.m.; the shades to the chamber were lowered at 6:42 p.m. There's no information on what happened between 6:33, when the second and third execution drugs were administered, and 6:42.
And then, between 6:44 and 6:56 (the time the execution was called off), here's what happened, according to the report:
The doctor checked the IV and reported the blood vein had collapsed, and the drugs had either absorbed into tissue, leaked out or both. The warden immediately contacted the director by phone and reported the information to the director. The director asked the following question, "Have enough drugs been administered to cause death?" The doctor responded, "No." The director asked, "is another vein available, and if so, are there enough drugs remaining?" The doctor responded "No" to both questions. The director requested clarification as to whether enough drugs had been administered to cause death. The doctor responded, "No." The director asked the condition of the offender, the warden responded that the doctor was checking the offender's heart beat and found a faint heart beat and the offender was unconscious.
Oklahoma Medical Examiner’s office has confirmed that Lockett's body was sent away for an independent autopsy to determine cause of death.
