Nyleen Kay Marshall (4) was having a picnic with her family in the Elkhorn Mountains, in Montana, when she disappeared. It was June 25th, 1983, and was last seen around 4 pm, while playing with some other kids. Right before she vanished, a man in a purple jogging suit was seen in the area, but it’s impossible to say if he’s connected to the disappearance.
Nyleen has never been found, but the story that followed her vanishing is a harrowing and surprising one. Three years after she went missing, a letter arrived from Wisconsin from a man who claimed that Nyleen was with him –he referred to her as Kay– and that she was loved and being taken care of. He said he had a good income and was homeschooling the girl. This person also shared details about the case that hadn’t been made public.
Also, investigators received several anonymous calls from a man claiming to be the one who had sent the letter, and they were traced to different public phones in Edgerton, Wisconsin. They claimed the content of the letter and the calls indicated possible sexual abuse against Nyleen, but they haven’t shared why. The person who contacted them has never been identified.
In 1990, Unsolved Mysteries did an episode about Nyleen’s case and someone called saying they believed one of their schoolmates was her. However, it turned out the girl was Monica Bonilla, another missing child that had been abducted by her father in 1982. She was reunited with her mother.
In another tragic twist, in 1995, Nyleen’s mother Nancy was raped and murdered in Mexico.
