John R. Gibbons was 21 and working as an attendant at the Leonard Service Station on Carpenter Road when he was killed during a holdup in May 1963. A lone gunman took $150 and fatally shot Gibbons. The Washtenaw County sheriff’s investigators launched an extensive inquiry, circulated a suspect description, and offered a $1,000 reward for information leading to an arrest and conviction, but the case went cold despite those efforts.

In February 1964 a suspect was located and held in a Tennessee jail, a development that briefly renewed hopes for resolution. The murder of John R. Gibbons, however, remains listed as unsolved. If anyone knew Gibbons, worked at the service station, or has information about the suspect described in 1963–64, please come forward.
