Supreme Court denies stay of execution for Oklahoma inmate Donald Grant

The U.S. Supreme Court has denied Donald Grant’s motion for a stay of execution.

Grant was convicted of the murders of two Del City women in 2001.

Grant’s attorney claims that he suffers from mental illnesses and is not fit for execution. Grant and fellow death row inmate Gilbert Postelle petitioned to change the method of execution over concerns about Oklahoma’s three-drug method.

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.

That request was denied.

Grant’s execution is scheduled for 10 a.m. Thursday. Postelle’s is scheduled for Feb. 17.
