The state of Oklahoma will begin carrying out lethal injections again, months after the botched execution of inmate Clayton Lockett.

The New York Times reported that on Thursday, in a renovated area, with a higher dose of drugs, the execution of Charles Warner will take place. Warner will be the first one conducted since the courts suspended all Oklahoma executions because of what happened with Lockett.

The 38-year-old was the subject of a problematic execution last April. Witnesses said Lockett attempted to speak and began to struggle on the gurney. He did not die until 43 minutes after the execution began.

At first, officials believed he died of a heart attack, but as previously reported, an autopsy revealed that he did in fact die from the lethal cocktail.

After that, the execution of Warner, who was set to die just two hours later, was postponed. He is now set to be put to death at 6 p.m. local time Thursday, although his attorneys have asked the courts for a stay.

Warner, 47, once lived in Oklahoma City with 11-month-old Adrianna and her mother, Shonda Waller. He was convicted of sexually assaulting and murdering the child in 1997.

During an interview last year, Waller said because of her Christian faith, she did not think Warner should be executed.
