Chiraq: 4 dead and at least 22 wounded over weekend

Spike Lee's next movie "Chiraq" is being filmed on Chicago's South Side. Meanwhile, in the real Chiraq it was another bloody weekend. Four people were murdered--including a man who was selling socks outside of a North Side Target store--and at least 22 others were wounded in shootings.

The fatal stabbing occurred in the Uptown neighborhood. The socks stabbing is the seventh homicide in that North Side neighborhood--which is two more than last year.
