Authorities said three people were killed and three others were injured in a shooting on I-57 on the South Side Sunday night.

Six people were in a vehicle in the northbound lanes of I-57 near 115th Street when shots were fired around 10:30 p.m., according to Illinois State Police.

A 19-year-old man, a one-year-old girl, and a 14-year-old boy were pronounced dead at the scene, according to police. The girl has been identified as Amara Hall by the Cook County Medical Examiner’s Office.

According to police, a woman was taken to the University of Chicago Medical Center in serious but stable condition. According to police, two boys, ages 13 and 14, were taken to Comer Children’s Hospital in serious but stable condition.

The SUV’s female driver was able to exit I-57 at 111th Street and Hamlet Avenue. The car was strewn with bullets.

Andrew Holmes, a crisis responder, intends to offer a reward for information leading to an arrest. He is horrified by the violence.

“It’s clear as day,” Holmes said. “You can see right through the vehicle. You seen the children in there. You seen the people in there. I mean come on, just simply turn yourself in because I’ll tell you this much, there’s technology on the expressway.”

Donovan Price, a local pastor and victim advocate, said he is comforting one of the families who has lost a child.

“The reaction is, unfortunately, too common here in Chicago,” Pastor Price said. “A mother, you know, barely able to stand up…. Anger, confusion, wanting information, just everything you could imagine times two.”

Meanwhile, no description of a suspect or vehicle has been released by state police. There has also been no word on what precipitated the shooting.
