Brad Sigmon, a convicted murderer in South Carolina, has chosen to die by firing squad over lethal injection or the electric chair. Sentenced in 2001 for a brutal double murder, Sigmon's decision arises from the horrific nature of all available execution methods.

On Friday, he became the first South Carolina inmate to choose the state’s new firing squad over lethal injection or the electric chair. Only three inmates in the U.S. have been executed by firing squad since 1976.
