Diarelle Duerson, 26, was killed in Detroit in a violent incident that remains unsolved. Investigators say progress on the case has been hampered by a lack of cooperation from potential witnesses, with fear cited as a reason people have not come forward.

Authorities believe Duerson’s murder may be connected to another homicide in the same area around the same time, that of Avery Johnson, and that possible link has expanded the scope of the investigation. No arrests have been announced and no suspects have been publicly identified.

This remains an open investigation. If anyone has information that could help explain what happened to Diarelle Duerson, please come forward to law enforcement.
