Va. man who murdered 2 scheduled for execution tonight

A condemned Virginia inmate is awaiting word from the U.S. Supreme Court as to whether his execution will go forward.

The court is the last hope for 37-year-old Darick Demorris Walker, who is set to die by injection at 9 p.m. Thursday at Greensville Correctional Center in Jarratt.

Gov. Bob McDonnell has refused to block the execution. Walker has two appeals pending before the court.

Walker was convicted of killing Stanley Beale in 1996 and Clarence Elwood Threat in 1997.

Virginia law allows the death penalty for anyone who commits two premeditated murders within three years.

Walker's attorneys claim that he is mentally unfit for capital punishment and that prosecutors withheld evidence casting doubt on eyewitness testimony at his trial.
