David Valladares, 23, was found fatally shot in the Marquette Park area on Chicago’s South Side on January 30, 2022. Police answered a person-down call about 1:05 a.m. in the 6400 block of South Saint Louis Avenue and discovered Valladares with a gunshot wound to the back of his head; the Cook County medical examiner pronounced him dead at the scene.

The shooting occurred in the Chicago Lawn neighborhood, described as predominantly Hispanic. The Chicago Police Department opened an investigation but reported no immediate suspects or arrests. Reports say there were few witnesses and investigators struggled to develop substantial leads; community members were asked to come forward but the response was limited.

In the months after the killing, the case remained unsolved and the family and local activists continued calling for more resources to help find answers. Does anyone who knew David or was in that area that night have information that could help the investigation?
