Clayton Lockett botched execution at Oklahoma is the state's first double execution since 1937. According to The Guardian's Katie Fretland, Clayton Lockett botched execution at Oklahoma had him writhing and groaning in pain, and 43 minutes later, he was declared dead after the apparently botched procedure.

Clayton Lockett is a convicted murderer and rapist who had shot his 19-year-old victim and ordered a friend to bury her alive. He was put on death list, and it was planned that Clayton Lockett botched execution at Oklahoma State Penitentiary will be longer than usual, according to a report by The Guardian.

A group of witnesses were allowed to watch the Clayton Lockett botched execution at Oklahoma, and Spokesman Jerry Massie for Oklahoma's corrections department detailed the procedure to them. He said that the first drug to be used under the state's new lethal injection protocol on the Clayton Lockett botched execution at Oklahoma, would take some time for it to take effect. He said to the witnesses, "Don't be surprised."

But according to The Guardian, the warning wasn't due as during Clayton Lockett botched execution at Oklahoma, Lockett eventually died 43 minutes after the drug was administered. And the 43 minutes gruesomely showed Lockett thrashing on the gurney, writhing and groaning in pain. It was only then that it became apparent to the witnesses that the execution had been botched.

Before the Clayton Lockett botched execution at Oklahoma, there has been a legal and political dispute in the state which resulted in a nationwide clash on the growing mystery behind drugs administered to prisoners on death list.

Governor Mary Fallin of Oklahoma reportedly challenged the authority of a panel of judges who halted the execution. This was done in order to deem the prinsoners' challenges over the constitutionality of the secrecy. The court apparently backed down, and eventually denied the inmates' claims.

However, the state attracted international attention when it scheduled two executions on the same night, just two hours apart, including the Clayton Lockett botched execution at Oklahoma.

This decision, however, is not the bit least good. The Clayton Lockett botched execution at Oklahoma was reportedly scheduled at 6pm. 12 selected media witnesses were invited and taken to the Oklahoma state penitentiary.

As told by Katie Fretland of The Guardian on her experience with the Clayton Lockett botched execution at Oklahoma, "We waited in the prison law library, as inmates banged on their cells and hollered to mark the event."

The procedure started at 6:23pm, but according to Fretland of The Guardian, "Lockett - as we had been warned - did not appear immediately to fall unconscious. Beneath a white sheet pulled to his neck, the restrained prisoner blinked and pursed his lips. At first he looked straight ahead, but after four minutes, he turned towards the witness area."

At 6:30pm, the Clayton Lockett botched execution at Oklahoma showed Clayton Lockett with his eyes closed and mouth slightly open.

Fretland continued of the Clayton Lockett botched execution at Oklahoma, "but when an official stood over him to check, it was clear something was wrong. "Mr Lockett is not unconscious," Trammell said."

By 6:33pm, Lockett was reportedly checked again and affirmed sedated. However, according to Fretland, "during the following minutes, Lockett lurched forward against his restraints, writhing and attempting to speak. He strained and struggled violently, his body twisting, and his head reaching up from the gurney. Sixteen minutes after the execution began, Lockett said "Man," and Trammell decreed the blinds be lowered. Before they fell, Lockett's right arm was checked."

After that is how witnesses saw the seeming ricochet of Oklahoma's secrecy with how it carries out lethal injections. Clayton Lockett botched execution at Oklahoma, in the middle, had the curtains drawn over the execution chamber. The public was not allowed to see the grisly scene of Clayton Lockett botched execution at Oklahoma.

Officials then picked up prison phones and left the room. A few minutes later, Director Robert Patton of the corrections department came to the viewing room and told witnesses, "We've had a vein failure in which the chemicals did not make it into the offender." According to The Guardian, it was unclear whether Lockett even died.

Patton answered reporters and told them that Clayton Lockett botched execution at Oklahoma had been administered with all three drugs in the protocol. However, as it became clear that the drugs were not taking effect, the prison doctor took notice and said that  "the vein into which the drugs were being administered had 'blown'."

Clayton Lockett botched execution at Oklahoma was explained as what "appears to be a massive heart attack". Lockett died inside the execution chamber, away from the public's eyes.
