Police said the boy was sitting on the sofa in the living room of a home in the 200-block of East 115th Street around 7:30 p.m. when people with him heard gunshots and discovered the boy had been shot, police said.
Police said the shots were fired from outside the home. It was not immediately clear if the boy was struck by a stray bullet, or if shots were intentionally fired into the home.
The boy was taken to Comer Children's Hospital in critical condition.
