On the night of September 12, 1985, 23-year-old Carmen Deluca was found fatally shot inside the temporary office trailer of the Gas & Save station at 163 Bridge Street in East Windsor, Connecticut. He was working the night shift as manager when a customer discovered him; he lived in Agawam, Massachusetts, and was engaged to be married.

About three hours after Deluca’s killing, a clerk at an AM/PM in nearby Orange, Connecticut, was shot during a robbery. Ballistic testing linked the same gun to both incidents. The surviving clerk described the shooter as a slender Black male, 18 to 25 years old, 5 feet 8 inches to 6 feet tall, and said the assailant was a passenger in a silver four-door Cadillac Brougham that may have had Georgia plates. Investigators believed robbery was the motive and noted the crimes’ proximity to major highways, including Interstate 91.

No arrests have been announced and the murder remains unsolved. Can anyone with information about the Cadillac, the suspect description, or movements along I-91 on September 12, 1985, help the investigation?
