In 1964, the Neshoba County Jail was located at 422 Myrtle Street. This is where the three civil rights workers (Goodman, Chaney, Schwerner) were taken and held when arrested on June 21. They were later released around 10:30 P.M. to return to the COFO office in Meridian. Two years later in 1966, Rev. Martin Luther King, Jr. knelt and prayed at this site.
