** ADVANCE FOR SUNDAY, SEPT. 7 ** FILE ** In this Sept. 22, 1955 file photo, a cotton-gin fan is presented as evidence in the trial investigating the death of 14-year-old Emmett Louis Till, in Sumner, Miss., on Sept. 22, 1955. The fan had been tied around the boy's neck with barbed wire when his body was found in the Tallahatchie River near the Delta community of Money, Mississippi, on August 31, 1955. The case is one of nearly one hundred unsolved racial killings that has been prosecuted under the FBI's Cold Case Initiative. Hopes were raised, say family members of the victims, but justice has not followed. (AP Photo/File)
