Devin Common, a 28-year-old African American man, was shot and killed on January 29, 2013, in the 7500 block of South Champlain Avenue in Chicago. The shooting happened around noon while Devin was on his way to get coffee; two other men were shot seriously and taken to Stroger Hospital in serious to critical condition. Police recovered a firearm under a bush near the scene and had one person in custody while searching for another suspect.

Family members said the loss compounded earlier grief: Devin’s mother, Kimberly Common, had already lost a son, Antonio Common, to gun violence in October 2011. The investigation later produced an arrest; Quovadas Mahomes was convicted of first-degree murder, aggravated battery with a firearm, and aggravated discharge of a firearm and received an aggregate sentence of 44 years. Reports from the probe say Mahomes tried to remove gunshot residue by urinating on his hands while in an interview room.

Does anyone have information about Devin’s movements that morning or the shooting on South Champlain Avenue?
