CHICAGO (AP) — Eleven people standing outside a family gathering Saturday night were shot including a young girl who was killed in what Chicago police believe was gang-related violence on the city’s South Side.

Four victims were children, police said Sunday. An 8-year-old girl was fatally shot, while a 1-year-old boy and a 8-year-old boy were each shot multiple times and listed in critical condition. A 9-year-old boy was also injured with a graze wound to his finger and hospitalized.

The department’s Sunday statement updated the number of shooting victims to 11 from 8 and gave new ages for the victims compared with a news conference late Saturday.

No one was in custody Sunday.

Department Deputy Chief Don Jerome told reporters Saturday that the shooting happened when shots were fired at a crowd standing outside a family gathering around 9 p.m.
