randomly reading a solved cold case, the person convicted was apparently mentioned as a suspect in Mary's case ?
"In a strange story on Sept. 9, 1966, 23 yr old Larry Stargel of Gainesville, GA pens a letter to police from Reidsville State Prison requesting an interview with local LE and the FBI regarding C&S Bank employee Mary Shotwell Little's disappearance in Atlanta on October 14 1965. Stargel names Gerald Mason as one of the two men responsible for the kidnapping & murder of Mary Shotwell Little. He stated that Mason had told him that they were hired for $5000 each by the husband Roy Little to kidnap & murder his wife. Later Larry Stargel refused to sign his statement to the FBI after mulling it over but did initial the statement. Just 18 months later, Mary Shotwell Little's replacement at C&S Bank, 20 yr old Diane Shields was murdered. Neither Roy Little or Gerald Mason were ever charged with the Mary Shotwell Little or Diane Shields murders. Both have remained unsolved for nearly 60 years."
