MCALESTER, Okla. – One day after his request for a stay of execution was denied, attorneys for Richard Glossip say they are not giving up.

Richard Glossip is set to die on Wednesday, Sept. 30 at 3 p.m.

Glossip was convicted of murder for the 1997 death of motel owner Barry Van Treese, though Glossip wasn’t the actual killer.

The man who bludgeoned Van Treese to death, Justin Sneed, testified that Glossip hired him for the murder.

On Monday, the Oklahoma Court of Criminal Appeals denied Glossip’s request for a stay of execution.

“This is not it, we still have 48 hours at least to work on this case and we can’t give up because we have a man that’s going to be put to death,” Lanita Henricksen, one of Glossip’s attorneys said.

On Tuesday, Glossip’s attorneys that they would appeal the governor for a stay of execution along with filing for a re-hearing in the Oklahoma Court of Criminal Appeals.

Gov. Mary Fallin released the following statement on Tuesday regarding the case:

“The state of Oklahoma has gone to extraordinary lengths to guarantee that Richard Glossip is treated fairly and that the claims made by him and his attorneys are taken seriously. He has now had multiple trials, seventeen years of appeals, and three stays of his execution. Over and over again, courts have rejected his arguments and the information he has presented to support them. We saw that again today, with the Oklahoma Court of Criminal Appeals affirming the notion that Glossip received a fair trial.

As I have said throughout the process, the role of my office is to follow the law and ensure justice is done. If a state or federal court grants Glossip a new trial or decides to delay his execution, I will respect that decision. If that does not happen, his execution will go forward on September 30, which is the date set by the Oklahoma Court of Criminal Appeals.

As always, my heart goes out to the family of Barry Van Treese, whose suffering has been made worse by uncertainty and delay.”

On Tuesday, the Court of Criminal Appeals denied Glossip’s motion to reconsider the case.

However, Glossip’s attorneys are not being discouraged.

Glossip’s team is also appealing to the U.S. Supreme Court.

Not everyone believes Glossip should be put to death.

On Tuesday evening, members and anti-death penalty activists will gather outside the U.S. Supreme Court to urge the justices to grant Glossip a stay of execution.
