Chinedu Madu, a 51-year-old Nigerian immigrant and cab driver for Chicago Carriage Cab, was fatally shot on January 8, 2015, in Chicago’s Lawndale neighborhood. The shooting occurred about 8:45 p.m. in the 1200 block of South Albany Avenue during an attempted robbery; Madu was shot in the chest and later died at Mount Sinai Hospital. He supported his wife, Vivian, their young son, and family in Nigeria and was remembered by colleagues as an outstanding, conscientious driver.

Police charged 23-year-old passenger Tyrese Bell with first-degree murder and three felony counts of aggravated battery to a peace officer. After the shooting, Bell went to an acquaintance’s house, hid the gun and admitted he had messed up, and was arrested and held without bond. Investigators reviewed nearby police-camera footage and possibly the cab’s camera, though it was unclear whether video evidence was useful. Did anyone know Chinedu or have information about that night that could help the case?
