ATMORE, Ala. (AP) -- Alabama has executed a man described by a police informant as trying to make a name for himself when he killed a convenience store clerk in 1994 during a robbery.
Thirty-seven-year-old Derrick O. Mason was given a lethal injection and was pronounced dead at 6:49 p.m. central time Thursday at Holman Prison.
Mason was the third person executed in the U.S. this week. On Wednesday, Georgia executed a man convicted of killing a police officer, while Texas executed a white supremacist for the dragging death of a black man.
Mason was the fifth person executed in Alabama this year and the third to die since the state changed the first drug used in its execution cocktail from sodium thiopental to pentobarbital. The change follows a nationwide shortage of sodium thiopental.
