Joseph Gwiazdowski was working as a taxi driver for the Diamond Cab Company when he was found in his vehicle in Arlington, Virginia, having been shot multiple times. The discovery on June 17, 1974, prompted a homicide investigation that never produced an identified suspect.

Investigators early on developed a lead suggesting the person who hired the cab may have called from a public telephone booth outside Steve’s Restaurant, but that line of inquiry did not result in an identification and the trail went cold. Decades later the case remains open, with no arrests and no publicly announced motive.

If anyone remembers seeing a Diamond Cab in Arlington on the night of June 17, 1974, or has other information about who might have hailed a cab outside Steve’s Restaurant, please come forward.
