OKLAHOMA CITY, Okla. — A man convicted of a brutal double murder in 2001 is scheduled to be put to death for his crimes this week.

The state of Oklahoma is scheduled to execute death row inmate Donald Grant on Thursday. He was convicted of killing two Del City hotel workers during a robbery in 2001.

The execution comes after a failed attempt to delay and change the type of execution that is carried out.

Earlier this month, a federal judge declined to halt the executions of Grant and fellow death row inmate Gilbert Postelle. Their lawyers argued in federal court that Oklahoma’s current practice of execution has a “substantial risk of severe pain and suffering,” citing convulsing observed during John Grant’s execution in October.

The judge ruled that the attorneys for the two convicted killers failed to prove methods used by the state had a substantial risk of severe pain.

Donald Grant’s public defender filed an appeal to the 10th Circuit Court of Appeals.
