Dylann Roof, the 22-year-old white supremacist convicted of murdering nine members of a historic black church in Charleston last year, will do little to spare his own life during the death penalty phase of his federal trial next month. Roof told a judge he plans on calling no witnesses when jurors decide next week decide whether he will face life in prison or the death penalty. The judge said prosecutors have submitted the names of 38 potential witnesses. Roof, 22, was found guilty on 33 counts, including federal hate crimes, earlier this month.
