On June 28, 2017, 16-year-old Jose Mendoza of Chicago’s South Side was found with multiple gunshot wounds and pronounced dead at the scene. He was a Hispanic teenager; the shooting occurred in a part of the city that the report notes has historically seen higher rates of gun violence.

The Chicago Police Department opened an investigation but, despite evidence-gathering and witness interviews, faced significant challenges. The case is cited alongside many 2017 homicides that remained unsolved.

Anyone with information about Jose Mendoza’s death is asked to contact authorities.
