A jury found Roof, a 22-year-old self-avowed white supremacist, guilty on Thursday local time of federal hate crimes resulting in the deaths of the nine black parishioners.
He was also found guilty of firearms violations and obstructing the exercise of religion for those he shot and killed during a Bible study at Emanuel African Methodist Episcopal Church on June 17, 2015.
Six women and three men, including the church pastor, were killed.
