ATLANTA — A judge has set the date for the execution of a Georgia death row inmate who was convicted of the 1978 slaying of an elderly woman in Savannah.

The judge ruled that convicted killer Roy Willard Blankenship will be executed on June 23.

If the execution is carried out then, he will be the first person put to death in Georgia using a new three-drug execution cocktail.

Georgia said in May it would use pentobarbital instead of sodium thiopental, which is in scarce supply nationwide. The state surrendered its supply of sodium thiopental to the Drug Enforcement Administration in March amid questions about how the state obtained its supply.
