South Carolina executed a convicted murderer by firing squad on Friday, the first use of the method in the United States in 15 years.

A convicted double murderer has been executed by firing squad, the first such execution in the United States since 2010, according to the South Carolina Department of Corrections.

Brad Sigmon, who admitted to killing his ex-girlfriend's parents, said he chose to die by bullets because he considered the other choices offered by the state to be worse.
