In a historic event, South Carolina has executed Brad Keith Sigmon by firing squad, marking the first such execution in the U.S. in 15 years. Witnesses described the execution as a violent and sudden spectacle, with accounts highlighting the horror of watching the procedure unfold. Sigmon was convicted of double murder, and his execution followed the dismissal of final appeals by the South Carolina Supreme Court. Reports indicate that he maintained a calm demeanor prior to the execution, while family members of the victims expressed closure at the outcome. This execution raises questions about the methods of capital punishment in the U.S., as the firing squad re-emerges in a system that has predominantly used lethal injection.
