Sylvia Alice Lwowski, 22, disappeared from Staten Island on September 6, 1975. That night she had gone to the movies with her fiancé, Charles Cirronella; according to him the pair argued, Sylvia threw her eyeglasses against the car dashboard and left the vehicle near K-Mart Plaza on Richmond Avenue. She was never seen again.

At the time she was wearing a white sweater, a green shirt, brown shoes, and a heart-shaped engagement ring, and she carried a brown handbag. Sylvia was a biology major at Wagner College. Searches and investigations have produced no significant leads. Both parents have since died; her brother continues to seek answers.

Does anyone who lived near Richmond Avenue in 1975 or who knew Sylvia or Charles have information that could help explain what happened that night?
