Oklahoma Killer Executed After U.S. Supreme Court Denies Stay

In April, Clayton Lockett writhed on the table for 43 minutes. But Thursday night's execution of Clayton Lockett only lasted 18 minutes.

Warner said the three drug cocktail felt like acid but witnesses said this execution was certainly less problematic than the last one.

But the execution did not start on time. It was originally scheduled for 6 p.m.

The Department of Corrections Director, Robert Patton, said he did not feel comfortable putting Warner on the execution table without a decision from the United States Supreme Court.

Warner's attorneys had filed an appeal Wednesday, requesting a stay in his execution. They called the state's new protocols "experimental."

Then at 6:20 p.m. a Department of Corrections spokesperson announced the Supreme Court had denied the stay 5-4 and the execution would take place.

The execution started about an hour later and witnesses said Warner made final statements such as:

"They pricked me five times."

"It burns"

"It feels like acid."

"No one should go through this."

Moments later witnesses said Warner seemed to fall asleep and at 7:28 p.m. he was pronounced dead.

Warner was convicted for the rape and murder of 11-month-old Adrianna Waller back in 1997.

He had been on death row since 2003 and our sister station's Tess Maune served as a witness for his execution.

Attorney General Scott Pruitt released a statement after the execution by saying Adrianna is finally receiving justice.
