CHICAGO (CBS) — A 14-year-old girl was critically wounded when she was shot while sitting in a minivan in the Gresham neighborhood late Monday night, likely the unintended victim of gang violence.

The girl was sitting in the minivan in the 7500 block of South Union Avenue, when two men walked up and opened fire around 11:30 p.m., police said.

The 14-year-old girl was shot in the back, and was taken to Comer Children’s Hospital in critical condition.

A 13-year-old girl was cut in the arm by broken glass, and was taken to St. Bernard Hospital in good condition. Police initially reported she was shot.

A 2-year-old boy also was in the vehicle at the time of the shooting, but he was not injured.

Police said the younger girl’s father is a documented gang member. He had been driving the minivan, and had just left the vehicle and entered a nearby home when the van was riddled with bullets.

Police said it’s unclear if the girls were the intended targets, but neither of them had any gang affiliations.

No one was in custody Tuesday morning. Area South detectives were investigating.
