BIRMINGHAM, Ala. (AP) — The federal government has reopened its investigation into the slaying of Emmett Till, the black teenager whose brutal killing in Mississippi shocked the world and helped inspire the civil rights movement more than 60 years ago. The Justice Department told Congress in a report in March it is reinvestigating Till’s slaying in Money, Mississippi, in 1955 after receiving “new information.” The case was closed in 2007 with authorities saying the suspects were dead; a state grand jury didn’t file any new charges.
