Gloria Jean Mazeika, 30, disappeared from Chicago’s south side in spring 1981 after leaving her grandmother’s home in the Calumet Park area on April 1. She had been drinking heavily that day and was last seen leaving in the company of an unidentified African American man; her destination and the man’s identity are unknown.

Gloria was petite, about five feet to five feet one inch tall and 118 to 125 pounds, with blond hair, hazel eyes, pierced ears, red burn scars on the tops of both feet from childhood, and significant scarring on her stomach from prior surgeries. The Chicago Police Department’s Area Two detectives opened the case (case number JC440096) and her file was later entered in national missing persons databases, but the investigation remains unresolved.

Many basic details are missing, including what she was wearing and whether she had any belongings when she left. Does anyone have information about Gloria, the man she was seen with, or her movements in Calumet Park on April 1, 1981?
