The man accused of slaying nine Black church members in Charleston will be indicted on a federal hate crime charge on Wednesday, according to an official close to the case. The official, speaking on condition of anonymity because the indictment hadn’t been publicly announced yet, told The Associated Press that a grand jury would indict 21-year-old Dylann Roof.

The move has been expected since Roof’s arrest after the June 17 shootings at Emanuel African Methodist Episcopal Church in downtown Charleston.
