The boy was attacked while standing on a sidewalk around 5 p.m. in the 200 block of West 110th Place, police said. He was pronounced dead at the scene.
Police said the boy was alone when shots rang out and struck him multiple times.
He was identified as Kevin Tinker by the Cook County medical examiner’s office.
He was standing outside a home that had been targeted earlier in the day, police Chief of Detectives Brendan Deenihan told reporters Monday. It was unclear if he was the target of the shooting.
Police released no other details. No one was in custody.
