Arturo Pina, 37, was shot and killed on April 11, 2016, in Chicago’s South Lawndale neighborhood, the Little Village area, on the 2800 block of South Kedvale Avenue. He was walking in the neighborhood when someone approached and fatally shot him.

Cook County prosecutors later identified Lamar Baker as the accused, describing him as a street gang enforcer. Prosecutors said Baker bragged on social media about the killing and posted photos of Arturo after the shooting, and alleged the slaying was tied to rival gang conflicts. A judge ordered Baker held without bond at his initial court appearance.

Arturo’s death was one of more than 760 homicides in Chicago in 2016, a year marked by a sharp rise in violence that heavily affected neighborhoods like South Lawndale. If anyone knew Arturo, saw him that day, or has information about the shooting, please share what can help the investigation.
