A jury on Thursday found Dylann Roof guilty of gunning down nine worshippers as they prayed in a historic black church in Charleston in June 2015, convicting him on all 33 counts of federal hate crimes that he faced for both the murders and his attempt to kill three additional church members.

Roof, 22, faces the death penalty in the June 17, 2015, massacre during a Bible study session at Emanuel African Methodist Episcopal Church, the oldest black church in the South. The self-proclaimed white nationalist has opted to defend himself in his federal trial’s penalty phase, scheduled to begin on Jan. 3.
