Andrew DeYoung was to be executed via lethal injection on Wednesday night in Georgia — an execution of some historic significance, in that it was to be the first to be videotaped in nearly two decades. But his execution was postponed at the last minute, and officials aren't saying why.

The reason it was being taped at all was because Gregory Walker, another inmate on Georgia's death row, wanted evidence to support his claims that the three-drug cocktail the state now uses to kill inmates isn't strong enough to knock them out completely. The state's execution on June 23 of Roy Blankenship had earned reports that the sedative pentobarbital hadn't entirely taken, and Blankenship had made "unusual movements" when he was injected with the other two deadly drugs — pancuronium bromide to paralyze him, then potassium chloride to stop his heart.

The Georgia Supreme Court had voted unanimously to allow the DeYoung execution to be taped, but prosecutors were steadfastly against it. No reason was given for the delay, with Attorney General Sam Olens saying only that it was "broader" than just logistics over the videotaping. Was it over concerns of the footage potentially leaking? It seems like a possibility.
