Roof, 22, has said he intends to represent himself for the sentencing phase of the trial, although U.S. District Judge Richard Gergel has said he does not support Roof's decision. Roof told Gergel last week he will make an opening statement but said he has "no plans whatsoever to call witnesses" during the sentencing phase.
The government plans to call more than 30 witnesses, mostly survivors and victims' family members, to testify in the sentencing phase. Survivors Polly Sheppard and Felicia Sanders, who testified during the guilt phase of the trial, are expected to testify again.
Roof appeared in court Monday at a sealed competency hearing, wearing a prison jumpsuit with his hands and feet shackled. The hearing was sealed, Gergel said, because of the risk of jurors’ being exposed to new information through the press or social media. Gergel said he would release information from Monday's hearing in 10 days, after Roof is sentenced.
"This is an incredibly sensitive moment in this trial," Gergel said.
After Monday's “day-long” competency hearing, according to a court filing, Roof was found to still be competent to stand trial and to self-represent. Roof asked that the sentencing phase be delayed by one day, and begin Wednesday instead of Tuesday; his request was granted by the court.
During the sentencing phase Roof cannot approach the jury, the witness stand or the bench, Gergel wrote in an order. Roof's standby counsel will sit in the first two seats at the defendant's counsel table closest to the center aisle and Roof will sit in the third seat, Gergel ordered.
Roof entered the church armed and "with the intent of killing African-Americans engaged in the exercise of their religious beliefs," according to the federal indictment against him. The parishioners welcomed Roof into their Bible study group, according to the indictment, after which Roof drew his pistol and opened fire.
In a video interview of Roof played in court, Roof laughed as he admitted to the shooting. He also said he used a Glock 45 to do it, according to the video. "I didn't say anything to them before I pulled it out, not even one word," Roof said of the gun in the video. "I mean they reacted after I shot them."
In the defense's opening statements during the guilt phase of the trial, attorney David Bruck told the court, "He did it ... You're probably wondering, so what we are doing here? Why does there need to be a trial? ... The practical reason is that the government has asked for the death penalty after conviction, and because of that, we have a procedure to go through.”
"Our society does not order the death penalty if there are reasons to choose life," Bruck added. "You're going to want to understand who this person was and why on earth he would want to cause so much grief."
Roof also faces a state trial in which he may again face the death penalty.
