CHARLESTON, S.C. — An unrepentant Dylann Roof was sentenced to death Tuesday for killing nine black church members during Bible study, the first person to face execution for federal hate crime convictions.

A jury deliberated his sentence for about three hours, capping a trial in which Roof did not fight for his life or show any remorse. He was his own attorney during sentencing and insisted that he wasn't mentally ill, but he never asked for forgiveness or mercy, or explained the crime.

And he threw away one last chance to plead for his life on Tuesday, telling jurors: "I still feel like I had to do it.''

Every juror looked directly at Roof, 22, as he spoke for about five minutes. A few nodded as he reminded them that they said during jury selection they could fairly weigh the factors of his case. Only one of them, he noted, had to disagree to spare his life.
