OKLAHOMA CITY – The mother of a death row inmate wants answers after learning the Department of Corrections isn’t ready to execute him.

Holding an old photo of her stepson, LaDonna Hollins’ mind takes a dark turn.

She pictures him in prison and pictures the woman he killed, Stephanie Neiman.

Hollins said, “I do ask myself why. I’ve asked Clayton why, and he just hangs his head and cries.”

Nearly 15 years ago, Clayton Lockett admitted to shooting Neiman several times and burying her alive.

A jury sentenced him to death for that and 18 other violent crimes he says he committed that night.

“Did he deserve it? I think so,” said Hollins. “He did. He did, and he’s going to die for it. So, let’s do this thing. Let’s stop putting it off.”

Three days before his execution, Hollins learned the Department of Corrections doesn’t have all of the drugs needed to do the job.

Drugs used in lethal injections have become more and more difficult to obtain.

FDA-approved manufacturers have refused to sell to any department of corrections facility using the drugs in executions due to the controversy surrounding the death penalty.

Oklahoma has the potassium chloride that stops the heart.

However, the state does not have phenobarbital, which causes unconsciousness, and vecuronium bromide, which stops a person from breathing.

Hollins said, “Why aren’t you prepared? This has been 15 years. I want to know.”

The Department of Corrections wouldn’t comment, but the attorney general’s office sent us the following statement:

“The Attorney General’s Office is exhausting all available options to ensure the punishment for this heinous crime is carried out, so that after nearly 15 years the family of Stephanie Nieman finally sees justice served.”

Information about the drug shortage was in response to stay of execution requests filed by Lockett, and another convicted murderer, Charles Warner.

In a lawsuit filed against the state in February, attorneys for both Lockett and Warner question an Oklahoma law that keeps the supplier of lethal injection drugs a secret,

They claim it could cause the men to die in a cruel or unusual way.

The men’s attorneys are asking for a stay of execution while their lawsuit makes its way through civil court.

“I want to know what mixture of drugs are you going to use now? Is this instant? Is this going to cause horrible pain?” said Hollins. “I know he’s scared. He said he’s not scared of the dying as much as the drugs administered.”

Still, his mother is torn at the sight of Neiman’s grave.

She said, “She died in pain though. So, I have to look at both sides.”

With that in mind, Hollins says she is prepared for her son’s death.

She doesn’t want the state to prolong her pain or the Neiman family’s pain any longer.

“This is hurtful,” said Hollins. “He’s got to go. We realize it. Let’s do it. Let’s do it with the right drugs.”

NewsChannel 4 tried to contact Neiman’s family with no luck.

However, her parents asked for the death penalty during the 2000 murder trial.

Hollins is also fighting for her son’s last meal.

He’s requesting a steak, baked potato and a slice of pecan pie.

Hollins said, “Is that too much to ask for? He will never eat again. They’re getting what they want. He’s dying. So, I feel he should have his steak.”

His mother says the department has denied his request because it exceeds the $15 the state will pay for last meals.

She says her son has the money to buy the food himself.

So far, the department has denied that.

Officials say the warden will decide if that will be allowed.
