Joshua Tremaine Jones, 27, was indicted last month on charges including weapons possession, larceny and failure to stop for police. He also faces assault charges for incidents at the Aiken County jail.
Jones is charged in the January death of Master Cpl. Sandy Rogers. She was the first female South Carolina officer killed in the line of duty.
Rogers was the second Aiken officer in as many months killed in the line of duty. Prosecutors are pursuing the death penalty against Stephon Carter in the death of Officer Scotty Richardson.
Jones is also charged in the fatal shooting of his girlfriend in her Augusta apartment.
