22-year-old Dylann Roof has been found guilty of hate crimes resulting in the deaths of nine black parishioners at church in Charleston in June last year.
According to reports, the jury reached its verdict in less than two hours.
Here's what has happened and what to expect. The defense instead tried to raise doubts about Roof's mental health and painted him as an impressionable, adrift kid drawn in by online white-supremacist propaganda; the prosecutor portrayed him as ruthless, hate-filled murderer.
The president-elect said in a statement announcing her nomination that Haley was "a proven dealmaker" who "will be a great leader representing us on the world stage".
If they find Roof guilty, the same jurors will return January 3 for the next phase of the trial to determine if he's sentenced to death or life in prison.
Roof, who said he was trying to ignite a race war, admitted to the killings shortly after he was arrested in a videotaped confession.
Gergel made a decision to set up the two-hour confession where jurors could watch as much or as little as they wanted to. They also heard from two survivors.
Roof also documented his hate in his journal, found in his vehicle when he was arrested. Roof believed that it was "not too late to take the country back from blacks", prosecutors said during the trial. Roof opened fire when the victims' eyes were closed in prayer at the end of the study session.
Roof told Federal Bureau of Investigation agents he killed about five people, and was later surprised when the agents told him nine people were shot and killed in June 2015 at Emanuel African Methodist Episcopal church.
A daughter of Ethel Lance, a victim in the shooting, said: "I forgive you for taking something precious from me".
But jurors may hear directly from Roof later.
Less than 24 hours after the massacre, Roof gave a two-hour taped interview to Federal Bureau of Investigation agents, part of which was played for the jury.
Jurors also said Roof, 22, was guilty of firearms violations and obstructing the exercise of religion for those he shot and killed during a Bible study. Many family members of those killed were in the courtroom as the guilty verdicts were announced.
"[He believes] the color of a person's skin makes them less than human", Williams said in his closing argument.
One woman had lain in a pool of her son and her aunt's blood, cradling her granddaughter as the massacre unfolded. "I wear a smile, because if you look at the pictures of all nine, they're smiling", Sanders said. "I was counting on that". "There's no place on Earth for him except the pit of Hell".
In the 911 call played in court, Sheppard begs a dispatcher to send help fast, saying "there's plenty of people shot down here".
Roof's mother had a heart attack during the emotional testimony and had to be hospitalised. His lawyers said in a court filing they fear he wants to avoid embarrassing testimony that the defense might have presented to try to get a jury to spare his life. Federal death sentences are rare, but the government has opted to seek one in this case, even though it has caused some unease among relatives of the victims. The pastor, who had offered Roof a seat next to him, was wearing a crisp white shirt and new suit in the image.
