13 People Shot in Mass Shooting in Chicago, Gang Banger Shooter Still At-Large #MurderCapitalUSA

A work week that began with a mass shooting in a Washington D.D. Navy Yard, that left 12 victims dead concludes with a mass shooting in Chicago in which 13 people, including a 3-year-old boy, were wounded.

It happened Thursday at about 10:15 p.m. local time in a working-class neighborhood called Back of the Yards in Chicago's South Side, NPR's Cheryl Corley reports.

She adds that "one witness told the Sun-Times that men fired at him from a car before turning toward a park. That's where the victims — several adults, two teenagers and the 3-year-old, were shot on a basketball court."

As of dawn Friday, Cheryl says, "no one had been taken into custody. Police were interviewing victims to determine the circumstances but say the shooting appears to be gang-related."

According to the Chicago Tribue, the 3-year-old "suffered a gunshot wound to the head at an ear that exited through his mouth, and was in critical condition at Mount Sinai Hospital, police said. The oldest victim, according to the Tribune, was 41 years old.
