An admitted white supremacist was sentenced to death Tuesday for killing nine black worshipers who’d invited him to study the Bible with them at a South Carolina church in 2015, ending a two-phase federal trial that exposed the killer’s hate-fueled motives and plumbed the chasms of grief left by the victims’ deaths. The jury, the same that convicted Dylann Roof in the murders last month, announced its verdict after deliberating less than three hours.
