Prosecutor Scarlett Wilson said today that 21-year-old Dylann Storm Roof had been indicted on the state charges, related to people who survived the June 17 attack.
Roof was arrested last month and charged with nine counts of murder, one for each person killed. He also faces a weapons charge.
Roof's defense attorney did not immediately return a message seeking comment.
Federal authorities have not said whether they will pursue hate crime charges against Roof.
