McALESTER — State Corrections Department officials stopped the execution of an inmate Tuesday after a botched lethal injection. Corrections Department Director Robert Patton later addressed members of the media, and announced after a blown vein, Clayton Derrell Lockett suffered a heart attack at 7:06 p.m., and was declared dead.
The execution officially began at 6:23 p.m. Patton said all three drugs had been administered, but they did not have the desired effect. Patton said Lockett died in the execution room.
Officials closed the curtains in the execution room 16 minutes into the procedure, after Lockett convulsed several times, his chest and head rising off the gurney at multiple points.
After about 20 minutes after the blinds were closed, Patton informed witnessing press the execution was being halted.
“It’s come to my attention, I’m stopping the execution,” Patton told press gathered in the execution chamber. “We’ve had a vein failure, in which the chemicals did not make it into the offender.”
Lockett grimaced and tensed his body several times over a three-minute period before the execution was shielded from the press. After being declared unconscious 10 minutes into the process, Lockett spoke at three separate moments. The first two were inaudible, however the third time he spoke, Lockett said the word “man.”
Lockett was convicted of the 1999 murder of Stephanie Neiman, 19, in Perry.
The execution of Charles Warner, which was scheduled to take place at 8 p.m., was stayed for 14 days, according to Patton.
