Dylann Roof has reportedly confessed to shooting and killing nine people at the Emmanual African Methodist Episcopal Church Wednesday night. CNN reports the Charleston, S.C. shooting suspect told investigators he wanted to start a race war by massacring the historically black church.

His roommate also told ABC News he'd been planning the act for six months. "He was big into segregation and other stuff," Dalton Tyler said. "He said he wanted to start a civil war. He said he was going to do something like that and then kill himself."

Roof is due in court this afternoon for a bond hearing after being charged with nine counts of murder and one count of weapon possession.
