Cass Stello Singleton, a 26-year-old African American man also known by his rap name Stello and a member of the rap group Team600, was shot and killed on July 21, 2015, in the South Side Washington Park neighborhood of Chicago. He was driving a Dodge Charger when a red sedan approached at a red light and multiple people, including some on the sidewalk, opened fire. Singleton was struck multiple times, including a fatal shot to the head, and died at the scene.

Police described the incident as a targeted drive-by shooting. No arrests had been made at the time, and investigators said a lack of witnesses willing to come forward hindered progress. Family and friends mourned his loss and called for justice as the community noted the larger problem of gang-related gun violence.

Does anyone in Washington Park or who followed Team600 have information that could help the investigation?
