Demetrius Tucker, a 25-year-old Black man from East Moline, Illinois, was shot and killed on March 16, 2020. The shooting occurred about 3:30 p.m. in the 1000 block of 51st Avenue; police found him in the street and he was taken to a local hospital, where he later died. The shooter or shooters had fled before officers arrived.

Investigators later identified 25-year-old Lamont Williams of Rock Island as a suspect. Williams was arrested in April 2020 by the U.S. Marshals on an active warrant for first-degree murder and held in the Rock Island County Jail with bond set at $2 million, 10 percent applicable. A high-risk search warrant connected to the probe involved multiple agencies and armored vehicles; Williams was not found during that initial search. On April 10, 2022, Williams waived a jury trial and pleaded guilty to second-degree murder; a pre-sentence investigation was ordered and sentencing was scheduled for June 6, 2022.

Anyone who knew Demetrius, witnessed the shooting, or has information about the case is asked to come forward.
