Episode 489: Nyleen Marshall

Four year old Nyleen Kay Marshall disappeared on June 25, 1983, in Helena National Forest near Clancy, Montana. She was attending a picnic with her family and playing with other children near a creek. Nyleen was last seen talking to an unidentified man wearing a jogging suit when she seemingly vanished within minutes. Authorities conducted a massive search involving thousands of volunteers, helicopters, and tracking dogs, but no trace of her was ever found. Two years later, an anonymous man sent letters and made phone calls claiming he had abducted Nyleen and was raising her, though investigators were never able to identify him or confirm the claims. The case remains unsolved and is still considered a non-family abduction. Anyone with information about Nyleen’s case is asked to call Jefferson County Sheriff's Office 406-225-4075 or The National Center for Missing and Exploited Children at 1-800-843-5678 reference # 601812.
