The first shooting, in the 300 block of North St. Louis Avenue in Humboldt Park, left 18-year-old and 21-year-old men wounded; both were taken to John H. Stroger, Jr. Hospital of Cook County. The two were at the memorial for Ramon Colon, shot on March 6 at the intersection of St. Louis and Hirsch, when shots were fired from a Volvo SUV, hitting the younger man in the buttocks and the older man in the leg. It's not clear how many people inside the SUV fired shots; several were wearing ski masks.
