FILE - This undated file photo shows Emmett Louis Till, a black teenager from Chicago whose body was found in the Tallahatchie River near Money, Miss. on Aug. 31, 1955. Willie Louis, a witness who went into hiding after testifying at the Till trial about hearing the lynching victim's screams, died July 18, 2013 in a Chicago suburban hospital. He was 76. After the trial, Louis fled his native Mississippi for Chicago. He changed his name and told no one of his connection to the case, not even his future wife. (AP Photo/File)
