[JURIST] No federal civil rights charges will be filed in the 1955 killing of Emmett Till [JURIST news archive], according to an FBI statement [text] issued Thursday citing the expiration of a five year statute of limitations. Till, a 14-year old African American boy, was brutally beaten and shot for allegedly whistling at a white woman. The case was originally tried [PBS trial overview] in 1955 with an all-white jury acquitting the two white suspects. The two men, who have since died, later confessed [Look interview] to the crime. Following a probe of investigative errors, the US Justice Department [official website] re-opened the case in 2005. The Till case leads a series of attempts by federal law enforcement authorities to settle unfinished civil rights cases. The Till file has been turned over to a local district attorney, who may still file state charges. AP has more.
