COLUMBIA, S.C. (AP) — The South Carolina Supreme Court on Wednesday rejected a request for more information on the firing squad from an inmate set to die next month over concerns about whether a man executed by the method last month suffered a lingering death.

The justices unanimously ruled that attorneys for Stephen Stanko did not prove the previous execution was botched even though lawyers argued the firing squad nearly missed the inmate's heart and prolonged his death. They also said all three bulleted fired may not have hit the prisoner's body.

Stanko, 57, is scheduled to die June 13. He has been sentenced to death twice in the state for two separate murders — one a friend and one his girlfriend as he raped her daughter.

Stanko has until Friday to decide if he wants to die by firing squad, lethal injection or the electric chair.
