Joseph Curtis, 57, was found dead in an alley along the Southfield Freeway in Detroit on August 28, 2017. Law enforcement treated the discovery as a homicide and opened an investigation into the circumstances of his death.

Investigators have faced obstacles common in many of the city’s violent cases: limited cooperation from potential witnesses and little physical evidence at the scene. No arrests have been made and no suspects have been publicly identified. The Detroit Police Department’s Cold Case Unit is still handling the file and has said it is using modern forensic techniques to try to generate new leads.

If anyone has information about Joseph Curtis, his last movements, or the area around the Southfield Freeway on or before August 28, 2017, please contact the Detroit Police Department.
