Kenneth J. Wallace, a 35-year-old African American man, was shot and killed on July 26, 2015 in the Humboldt Park neighborhood of Chicago. The shooting happened in the early hours; he was pronounced dead at the scene. Reports say he was shot multiple times in what appeared to be a targeted attack. Witnesses heard gunfire and saw a vehicle speeding away.

Investigators initially had few leads and there were no immediate arrests. Detectives looked into motives and interviewed friends, family and neighbors; those inquiries reportedly found no known gang ties or criminal affiliations for Wallace, which investigators said made the motive perplexing. The community held vigils and pressed for information as the investigation continued.

A later witness reportedly provided crucial information leading to an arrest and a first-degree murder charge, with the suspect believed to have had a personal dispute with Wallace.
