Omar Knott was 19 when he was fatally shot late on the evening of August 3, 2016, on Detroit’s west side. Officers responding to reports of gunfire found Knott at 16701 Forrer Street; he died of gunshot injuries.

Investigators opened a homicide probe, but the investigation stalled and the case went cold amid the city’s backlog of unsolved killings.

Anyone who knew Omar, was in that neighborhood on August 3, 2016, or has information that could help the investigation is urged to come forward.
