Condemned South Carolina inmate Brad Sigmon has chosen to die next month by a firing squad, a method of execution that has not been used in the U.S. in 15 years.

An inmate on South Carolina's death row has chosen to die on March 7 by firing squad, his lawyer said Friday. 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.
