Brad Sigmon will be the first person executed by firing squad in South Carolina and the oldest person ever put to death in the state.

A man on death row will become South Carolina's first ever execution by firing squad later this week after revealing why he chose the gruesome execution method. Brad Sigmon was put on death row back in 2002 after being convicted for the double murder of his ex Rebecca Barbre's parents in South Carolina.

Brad Sigmon, 67, convicted of murdering his ex-girlfriend's parents in 2001, is scheduled to be executed on March 7.
