CHICAGO (AP) — A 61-year-old woman became the fourth person to die from a series of shootings this month by a Chicago gunman who was later killed in a suburban police shootout, authorities said Sunday. Marta Torres, an Evanston woman who had been in critical condition for a week after being shot at an IHOP, died Saturday at a hospital, according to the Cook County medical examiner’s office. Her autopsy was scheduled for Sunday. According to police, 32-year-old Jason Nightengale, of Chicago, shot seven people in a series of attacks Jan. 9 over a roughly four-hour period. Most of the attacks happened on Chicago’s South Side before Nightengale drove to Evanston, just north of the city, where he shot Torres before officers killed him during a shootout.
