Dylann Storm Roof is an American white supremacist, Neo-Nazi, and mass murderer who is currently awaiting execution on death row at USP Terre Haute for perpetrating the Charleston church shooting on June 17, 2015, in the U.S. state of South Carolina. During a Bible study at Emanuel African Methodist Episcopal Church, Roof killed nine people, all African Americans, including senior pastor and state senator Clementa C. Pinckney, and injured a tenth person. After several people identified Roof as the main suspect, he became the center of a manhunt that ended the morning after the shooting with his arrest in Shelby, North Carolina. He later confessed that he committed the shooting in hopes of igniting a race war. Roof's actions in Charleston have been widely described as domestic terrorism.
