The long weekend was marred by violence in Chicago, as 12 people were killed and another 60 were injured in shootings across the city. The last incident occurred around 3:30 p.m. Sunday afternoon when two men were shot on on South Ashland Avenue; one was killed after being struck in the back and another was left in critical condition after being hit in the arm and chest.

A Saturday evening shooting in Lawndale sent six people to Mount Sinai Hospital. Terry Patterson, 49, was fatally wounded; another four were left in critical condition and one person was more stable. As of yesterday morning, no one was in custody.

A suspect was arrested in connection with the shooting of 5-year-old Jaden Donald, who was taken to Advocate Christ Medical Center after being shot in Cooper Park just after midnight on Friday. Darrell Chambers, 24, was charged with first-degree murder and three counts of aggravated battery with a firearm on Saturday. 

Chicago Police Superintendent Garry McCarthy released a statement saying: "While to date we've had significantly fewer shootings and significantly fewer murders this year, there's more work to be done and we won't rest until everyone in Chicago enjoys the same sense of safety."

Even with this past weekend's violence, CBS News reports that there have been less homicides in Chicago over the first half of 2013 as compared to the same time period last year.
