Chicago authorities say seven people were killed and six wounded in gun violence in one day.
Among those killed Saturday was a 34-year-old man whose mother had already lost her three other children to shootings. Police say Ronnie Chambers, who was his mother's youngest child, was shot in the head while sitting in a car.
Police say two separate double-homicide shootings also occurred Saturday about 12 hours apart.
In one, a 16-year-old boy and a 32-year-old man were killed.
In another, two men were shot at a hamburger stand on the city's South Side. Police say the victims were roommates in their 40s.
Chicago's homicide count eclipsed 500 last year for the first time since 2008. Chicago's homicide rate was almost double in the early 1990s, averaging around 900.
