Dylann Roof has requested a new trial after he was convicted and sentenced to death for the June 2015 murder of nine black churchgoers at the Emanuel AME Church in Charleston, the Associated Press reports. Roof, a white supremacist, admitted to the killings in taped confessions before the FBI, and said he did not regret the massacre. He was sentenced to death in January. On Friday, Roof’s attorneys filed a motion for a new trial, arguing that federal prosecutors did not show enough evidence that Roof’s internet activity and gun purchases extended out of state, and that only a state court would have had proper jurisdiction to try him. A U.S. District Court judge overruled the motion.
