Grayson’s three accomplices managed to escape execution because they were under 18 at the time of Deblieux’s murder

Prison officials in Alabama have executed convicted murderer Carey Dale Grayson, marking the state's sixth death sentence and third using the nitrogen gas method so far this year.

An Alabama prisoner convicted of the 1994 murder of a female hitchhiker became the third person executed by nitrogen gas in both the U.S. and Alabama.
