Recently released court documents show that investigators sought to obtain surveillance video that could help them piece together the facts behind a Dallas police officer’s killing of her Black neighbor. Amber Guyger, who’s white, is charged with manslaughter in the shooting death of Botham Jean on Sept. 6 in his own apartment. The three warrants, dated Sept. 14, indicate that investigators with the Dallas County District attorney’s office have been seeking additional video footage from surveillance cameras on townhouses across the street from the apartment complex where Jean and Guyger both lived, the Dallas Morning News reported on Saturday.
