Shirley Hyman was 31 when she was last seen in Philadelphia on the evening of August 28, 1981. A mother of three who enjoyed dancing, bowling and singing in the church choir, Shirley was at the Park Avenue Cafe near 22nd Street and Hunting Park Avenue, a place where she often played pool. Witnesses say she left the bar with two men and got into a blue van while visibly upset and crying; those men were later questioned and said they had dropped her off safely.

At the time she disappeared Shirley was described as 5 feet 1 inch and about 160 pounds, with red or auburn hair usually pinned in a bun, brown eyes, pierced ears, eight healed scars on her upper torso and a distinctive V shape to her bottom row of teeth. She sometimes used the names Shirley Hickman or Shirley Hickman-Middleton and was last seen wearing a white sweater, blue jeans, tan slide-on sandals, sunglasses and a wreath-shaped ring. The investigation produced no significant leads and the case has gone cold.

Does anyone who knew Shirley, her friends from Park Avenue Cafe, or people who were in that neighborhood the night of August 28, 1981, have information that could help explain what happened?
