Jonathan was last seen during a family gathering at Jacksonville Beach in Florida on June 11, 1968. He has never been heard from again. Although the police believed the child drowned, witnesses saw him follow his father to a snack bar and his mother believes he was abducted by a man and a woman standing outside the establishment. He was wearing blue swim trunks with a red stripe. He was 3 years old at the time. Jonathan has previously fractured his femur.
