Perhaps the case is connected with that of Wanda Maldonado, 9, who was last seen alive about 7pm Friday, July 4, 1969, while playing hide and seek in front of her house at 598 Belmont Avenue, East New York, Brooklyn. Her body was found Wednesday, July 9, 1969, in an unused railroad cut in a Long Island railroad yard near the intersection of Liberty and Junius Avenues. An attempt was made to hide her unclothed body by piling her clothes and a wooden crate on top of her in a shallow grave that had been dug. Some young boys playing in the railroad yard apparently accidentally knocked the crate over, uncovering the body.
Maldonado had come with her family to New York from Puerto Rico just six months before she was murdered, and the family knew little English. A man in a white car with NY plates was reported to have tried to entice little girls into his car by offering candy shortly before Maldonado's murder. Maldonado was raped and strangled, and the medical examiner believed she was murdered within hours of her disappearance.
