Marrio Battles, a 39-year-old African American man, was shot to death on September 2, 2017, in Chicago, Illinois. He was found with multiple gunshot wounds; officials describe the incident as a drive-by shooting.

Investigators report a lack of witnesses willing to come forward has been a challenge in the case. Battles’ death prompted community calls for action on gun violence and public safety, and his family and friends continue to mourn and press for justice.

Has anyone in Chicago from that time period seen or heard anything that could help?
