Chicago's deadly day: Shootings kill 7, wound 6

CHICAGO 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 in their 40s were killed, and another injured, after a shooting outside a 24-hour hamburger stand, reports CBS affiliate WBBM in Chicago.

"We just getting something to eat. That's it, and all we heard was boom, boom, boom. Look up it's my man laying, both of them laying, I seen both of them laying, but I didn't really know it was my man until I looked and I seen him and I just couldn't believe it," witness Lamar Baker told WBBM-TV.

Baker said his friend was celebrating a birthday, and was a father of five young children, according to WBBM-TV. The second victim had just gotten off work.

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.
