Chicago police say a 15-year-old high school student who was wounded during a gun fight between a suspected bank robber and investigators was likely shot by a suburban police officer.

First Deputy Supt. Anthony Riccio says the robbery happened in Des Plaines and that a Des Plaines officer pursued the suspect into Chicago.

The suspect ran into the music store where the Lane Tech High School sophomore was working. The officer followed the suspect into the store and gunfire was exchanged.

The suspect was wounded and later died, while the teen was shot in the arm and stomach. Riccio says the boy’s condition is improving.

The Cook County medical examiner’s office identified the bank robber as 32-year-old Christopher Terrell Willis of Chicago.

Authorities say a suspected bank robber shot a Chicago police officer in the head, badly wounding him, before another officer killed the suspect in a shootout in which a teenage bystander was wounded.

Police Superintendent Eddie Johnson said at a news conference late Tuesday that the chaotic chain of events began hours earlier when two men robbed a bank in the suburb of Des Plaines.

Police say they arrested one of the suspects after a brief foot chase, but the other stole a car and sped off. Police were waiting for him when he exited a highway on Chicago’s northwest side and he fired on their squad cars, wounding the 46-year-old Chicago officer before fleeing into a nearby music store.

A Des Plaines officer shot and killed the suspect during a shootout in the store. A 15-year-old boy who was getting a music lesson there was wounded and was hospitalized in stable condition. It wasn’t clear who shot the boy.

The wounded officer was in serious but stable condition.
