A federal jury found Dylann Roof guilty on all 33 counts, including murder and hate crimes, related to the June 2015 murder of nine churchgoers in Charleston, South Carolina.
Roof, the 22-year-old South Carolina white supremacist admitted to killing the worshipers in an African-American church, chuckling throughout his confession.
Assistant U.S. Attorney Nathan Williams told the jury, “He needs to be held accountable for every bullet,” Assistant U.S. Attorney Nathan Williams told the jury in closing arguments.
His defense attorneys acknowledged his responsibility for the murders but are seeking a life sentence for him. The jury will decide in January whether to sentence Roof to death or life in prison.
18 of the 33 counts carry a maximum sentence of death.
According to CNN, the jury deliberated for approximately two hours after closing arguments before handing in the verdicts. They will listen to more evidence in the penalty phase of the trial before making a decision on his fate.
Roof has said he wants to represent himself in the sentencing phase, scheduled to begin Jan. 3.
