Sherry Gordon, 12, and her cousin Theresa Hall, 10, were last seen by their parents around 8 p.m. on Oct. 31, 1984, before the girls went trick or treating with Theresa's sister, 7-year-old Patricia Hall. Construction workers found the girls' bodies two days later in a vacant apartment at the public housing project where Johnson lived. Patricia was alive and in a closet, while the other girls had been strangled, one with a piece of clothing and the other with an electrical cord.
