Weekend violence in Chicago is down compared to the past month, but it still claimed the lives of at least three people. The youngest victim was a 13-year-old boy, who was shot in the chest in a drive-by shooting. More than 200 people have been injured in weekend shootings in the past six weeks, at least 30 have been killed. City officials say most of the violence is gang related. They collected more than 55-hundred guns Saturday as people voluntarily handed them over in an effort to take weapons off the streets.
