COLUMBIA, S.C. (AP) — A South Carolina man convicted of murder was executed by firing squad Friday, the first U.S. prisoner to die by that method in 15 years. Three volunteer prison employees used rifles to carry out the execution of Brad Sigmon, 67, who was pronounced dead at 6:08 p.m.

Brad Sigmon is only the fourth person executed by firing squad in the United States since the death penalty resumed nationwide in 1976.
