Chicago Weekend Violence: 2 Killed, 6 Wounded In Saturday, Early Sunday Shootings

Two men were killed, one of them a teenager, and at least six others were hurt in shootings in Chicago Saturday evening into early Sunday.

Edgar Delgado, 17, of the 3400 block of North Central Park Avenue, was fatally shot just before 8 p.m. in the city's Avondale neighborhood, CBS Chicago reports. He was pronounced dead at Our Lady of Resurrection Medical Center at 8:19 p.m.

In the city's Noble Square neighborhood, a 25-year-old man died after he and one other man were shot, just before 3 a.m., outside the Krush nightclub in the 1600 block of North Elston Avenue. The second man remained in critical condition early Sunday, Fox Chicago reports.

The Chicago Tribune has detailed other shootings in the city's Logan Square, North Lawndale, South Austin and Woodlawn neighborhoods. At least three of the five men injured in these overnight shootings were listed in serious condition.

No one is in custody in any of the shootings, while detectives continue to investigate.

While the city's overall crime rate, as of last month, was down 20 percent compared to the same month last year, the number of homicides more than doubled the number recorded during that same period. In an attempt to bring down that number, Chicago police have targeted the city's two most violent districts, Englewood and Harrison, in a policing initiative launched last month. In 2011, the two districts alone accounted for almost one-quarter of the murder and shooting incidents citywide.

"Crime knows no boundaries," Chicago Police Superintendent Garry McCarthy said of the new initiative last month. "Our goal is to effect a significant impact citywide by focusing on the areas most susceptible to violent activity in our communities."
