A Georgia man tonight could be the first inmate put to death since a U.S. Supreme Court review halted executions last year.

The Georgia pardons board has denied William Lynd's appeal for clemency. The 53-year-old Lynd has a request for a stay before the Georgia Supreme Court, but preparations for the execution are moving forward. It's scheduled for 7 p.m. Eastern time.

This would also be the first execution in the U.S. since the Supreme Court ruled last month that Kentucky's method of execution with a three-drug lethal injection is constitutional. Roughly three-dozen states use a similar method, including Georgia.

Lynd was sentenced to die for kidnapping and fatally shooting his live-in girlfriend, Ginger Moore, in 1988, after the two consumed Valium, marijuana and alcohol. Prosecutors say Moore suffered a slow, agonizing death, regaining consciousness twice after being shot in the head.
