Dylann Roof, who is currently being sentenced after he was convicted last week of killing nine black worshippers in Charleston, said on Wednesday he doesn't intend to introduce any evidence or call any witnesses to the stand during his defense. The 22-year-old, who is defending himself, said during the hearing that he'll only make an opening statement. He faces a possible death sentence in the case. The sentencing phase of the trial begins on Jan. 3. "As far as I know, I am not intending to offer any evidence at all or call any witnesses whatsoever," he told the judge. U.S. District Judge Richard Gergel told Roof he may change his mind about serving as his own counsel up until the start of the proceedings. "You know my feeling on this," Gergel said. "I think it's a bad idea."
