Summary 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.
