Characteristics: Nyleen had a chipped lower baby tooth at the time of her disappearance.
Details: On June 25, 1983, four-year-old Nyleen Marshall vanished while on a trip with her mother and step-father to the Elkhorn Mountains. That day, the Marshalls and several other families traveled to a picnic area in the Helena National Forest. At around 4pm, she and several other children went playing along the banks of a shallow creek. Some of them noticed her talking to an unidentified man in a purple jogging suit. He tried to get her to play the game "follow the shadow". He was the last person to be seen with her before she vanished.
On November 27, 1985, the National Center for Missing and Exploited Children received an anonymous call from a man who claimed that he had Nyleen. Two months later, an organization called "Child Find of America" received a typewritten letter from the same man. He claimed that he was raising her as his own child and that he now calls her "Kay". He also claimed that he loved her and did not plan on returning her to her family. Although he claimed that he was taking care of her, he also mentioned committing acts that are considered child sexual abuse.
Over the next six months, Child Find of America received two more letters and another two phone calls from the man. They came from Madison, Wisconsin; the FBI was able to trace some of the calls to specific phone booths there and Edgerton. However, once the ones where they came from were found, they subsequently stopped. The letter was also postmarked from the Madison area. The man indicated that he has traveled with Nyleen to several different locations in the United States; this matches the alleged sightings of her throughout the country.
In June 1990, authorities received another lead in the case. Nyleen's uncle saw two composites for a man and woman wanted for child abduction in another part of the country. He believes he saw them on the first day of the search for Nyleen.
To date, no trace of Nyleen or her abductor have been found.
Suspects: Nyleen was last seen talking to a man in a purple jogging suit. He has never been identified and is considered a prime suspect in the case.
The unidentified man that has contacted several missing persons agencies is considered a possible suspect. He claims that he lives off of substantial investments and that he and Nyleen travel frequently. He allegedly traveled with her to San Francisco, New York, Oklahoma City, New Orleans, Nashville, Chicago, Puerto Rico, Canada, and Great Britain. He has sent letters and made phone calls from Madison and Edgerton, Wisconsin. The man claims that his parents and younger sister were killed in a car accident when the latter was nine.
An unidentified man and woman wanted for a separate child abduction are considered possible suspects. Nyleen's uncle believes that he saw them on the first day of the search for her.
The Jefferson County Sheriff's Office has also indicated that her stepfather was a person of interest in this case.
Extra Notes: This case first aired on the November 21, 1990 episode.
Results: Unresolved. Subsequent to the airing, a viewer believed that one of his schoolmates was Nyleen, but when police went to her house, she turned out to be another missing child, Monica Bonilla, who was abducted by her father. She was reunited with her mother, while Nyleen's disappearance remains unsolved.
Sadly, her mother, Nancy, was raped and murdered in Mexico in 1995. It is unknown if her death is connected to Nyleen's disappearance.
