Two teenagers and an infant were killed, and three more people were hurt after a shooting on a Chicago interstate highway, officials said Monday.

The shooting occurred Sunday at around 10:30 p.m. on the I-57 expressway near 111th Street in the South Side, Illinois State Police trooper Josh Robinson said.

Robinson said the investigation "is still in its infancy."

State police did not share whether a suspect has been arrested.

Public safety in Chicago is a major factor for voters in the upcoming mayoral election. Mayor Lori Lightfoot has taken the most heat for increased crime, with homicides hitting a 25-year high in 2021 with roughly 800.
