Marcus Sanfratello was Teresa Peroni's boyfriend when she went missing after attending a party in the Selma area. A skull was found on nearby property nearly 15 years later. New DNA technology was used, witnesses were reinterviewed and a grand jury indicted Sanfratello. He pleaded guilty to Manslaughter and must serve a minimum of ten years in prison.
