Donald Vaughn was 29 when he was killed in Detroit, Michigan; his death was ruled a homicide on June 12, 2016. Beyond that date and ruling, authorities have released very little about the circumstances of the killing.

The Detroit Police Department’s Murder Bureau handled the investigation, which stalled as it joined the city’s larger backlog of unsolved homicides. Investigators reportedly encountered a lack of physical evidence and reluctance among potential witnesses to come forward; no arrests have been announced and no suspects have been publicly identified.

The case remains open and unsolved. If anyone knew Donald Vaughn, saw something on or around June 12, 2016 in Detroit, or has information that could help, please come forward to the Detroit Police.
