Tracey Morgan was a 25-year-old African American man who was fatally shot on October 13, 2015, in Chicago. He had attended a Chicago Police Department gang call-in meeting at Friendly Temple Church of God in Christ that evening. After the meeting his mother picked him up; while driving in the 8200 block of South Lafayette Avenue a silver sedan passed, cut in front of their car and stopped, and another vehicle boxed them in. Two gunmen approached and opened fire. Morgan was struck at least 11 times and died at Advocate Christ Medical Center in Oak Lawn at 9:27 p.m. His mother was wounded in the arm and survived.

Authorities identified the attack as part of retaliatory violence between rival gangs. Khalil Yameen, a reputed member of the Killa Ward faction of the Gangster Disciples, was charged with Morgan’s murder and held without bail; investigators said cellphone tower records and other evidence placed Yameen at the scene and that Yameen and another shooter had attended the same call-in meeting as Morgan. The shooting was followed by further retaliatory killings, including the later slaying of 9-year-old Tyshawn Lee.

Does anyone have information about Morgan’s movements that night or about the vehicles described at the scene?
