The two men, Martin Miranda and Andres Guerra, both 19, were eventually captured and charged.
From an article:
Navarette was standing outside a car parked on 30th street near Kedvale Avenue, with two adults and their children in it, when an SUV driven by Guerra drove up, said Steve Campbell, a spokesman for the Cook County state’s attorney’s office.
Miranda, who was in a rear seat of the SUV on the passenger side, lowered the window and shouted “2-6,” a slogan for the 2-6 street gang, prosecutors said.
Navarette responded, “What?” Miranda opened the car door and shot Navarette once with a sawed-off shotgun, prosecutors said. Miranda pumped the shotgun and pointed it at the people in the car, then turned back to Navarette, who was lying on the ground, and shot him twice more..
