[JURIST] An anonymous donor has posted a $100,000 reward for information leading to charges in the unsolved "Freedom Summer" slayings of 3 civil rights workers in Mississippi in June, 1964 (read this background news report on the 40th anniversary opf the murders from WBLT in Jackson). The three volunteers, in the state to help to register black voters, were allegedly beaten and shot to death by Klansmen on a dirt road as they drove to a local church to investigate a fire. Nineteen people were indicted in the slayings for violating federal civil rights law, but the state never brought any murder charges. The reward is being administered by the Mississippi Religious Leadership Conference. AP has more.
