Mohamed Omar Aden, 25, was shot to death in the early morning hours of June 1, 2013, on the 2400 block of Washington Street NE in northeast Minneapolis. Police were called at about 4:34 a.m., and the Hennepin County medical examiner later identified Aden as the victim.

Investigators sketched a motive linking Aden to earlier violence in the city: he was believed to have been targeted in retaliation for his suspected role in the May 2011 killing of Guled Mohamed, who belonged to the Somali gang Madibaan With Attitude. Coverage at the time noted a spate of shootings of Somali American men around that period, but authorities did not announce an arrest in Aden’s case and no suspect was publicly tied to the killing in contemporaneous reporting.

Does anyone have information about who was seen in that area the morning of June 1, 2013, or other details that might help clarify what happened?
