Summary based on the NamUs case record (MP4532) and 7 other sources
On a summer evening in 1969, a 15-year-old girl named Cynthia Dawn Constantine disappeared from her home in Oakdale, New York. It was July 11th, and Cynthia had taken her dog for a walk along the railroad tracks of the Montauk Branch of the Long Island Railroad, a frequent routine for her. Just minutes after she left, her dog returned home alone, the leash still attached to its collar. Cynthia was nowhere to be found. She was last seen wearing a white blouse, black Bermuda shorts, and orange sneakers, and possibly a yellow metal chain with a cross pendant. Cynthia had blonde hair and blue eyes, wore glasses, had a mole on her throat, and a discolored front tooth. A notable detail of her physical description was that she had fractured her lower right arm the previous summer.

The hours turned into days, and a search for Cynthia ensued. Three young boys reported seeing her walking into the woods with her dog near the train station. Earlier that day, Cynthia and her brother had discovered a muskrat den in the woods, and she had expressed a desire to go back and see it. When her brother led authorities to the location, they found tracks consistent with a girl and a dog, but rain washed them away before they could be properly examined. Community members, including the Boy Scouts and local fire department, joined in the search, scouring the woods and dragging a nearby lake, but no trace of Cynthia was found. Her family was adamant that she would not have run away, describing her as a quiet and reserved girl who was not a troublemaker. She had no history of running away and had left all of her belongings behind. Adding to their certainty was the fact that her pet rabbit was about to give birth, an event Cynthia was eagerly anticipating.

Years have passed since Cynthia Constantine vanished, and her case remains unsolved. Investigators explored various leads, including the possibility that her father was involved, as he had laid a new cement floor in the basement of his bicycle shop around the time of her disappearance. Several other local individuals were also considered as potential suspects, but no one was ever publicly named or charged. The proximity of her disappearance to the train station also raised the possibility that someone from outside the area could have been involved. In 1978, the discovery of a woman's remains in a nearby state park briefly led to speculation that they might be Cynthia's, but it was later determined they were not. Though her parents have since passed away, her brother continues to hope for answers. The disappearance of Cynthia Constantine is a long-standing mystery, a story of a young girl who went for a walk with her dog and never came home, leaving her family and community with unanswered questions.
