South Carolina is preparing to execute 67-year-old Brad Sigmon by firing squad on Friday, marking the first use of this method in the state in 15 years. The inmate was given the choice between electrocution, lethal injection, or the firing squad. South Carolina’s firing squad procedure is highly structured. Sigmon’s defense team attempted to halt the execution earlier this week, citing concerns about the lack of transparency surrounding South Carolina’s lethal injection procedures. Since the death penalty was reinstated in 1976, South Carolina has not granted clemency to any death row inmate.
