Crispin Coliz, 29, was shot and killed on December 16, 2016, on West Grace Street in Chicago’s Dunning neighborhood after an argument at a convenience store. Federal charging documents allege the shooting was carried out by two members of the Milwaukee Kings street gang, Jose Martinez and Santo Lozoya, and that the killing was tied to efforts to maintain or increase standing within the gang.

Authorities connected the slaying to organized criminal activity and pursued federal charges against the accused, framing the homicide as part of a broader pattern of gang violence aimed at asserting dominance in the area.

Does anyone have information about Coliz, the convenience store on West Grace Street, or the events that led up to the argument?
