A South Carolina death row inmate has chosen to be executed by a firing squad next month rather than by lethal injection or the electric chair.

Brad Sigmon, 67, who was convicted in 2002 of killing his ex-girlfriend’s parents, would be the first condemned prisoner to be executed by that method in South Carolina and the first inmate to die by firing squad in the U.
