Stewart was shot twice in the chest, and was taken to John H. Stroger Jr. Hospiital of Cook County in critical condition. The girl was shot in the arm and shoulder, and taken to the University of Chicago’s Comer Children’s Hospital, where her condition was stabilized.

Stewart is the nephew of community activist Andrew Holmes, who grew emotional talking about his nephew. He spent the night with his family at the hospital. Although he’s helped console the families of many gunshot victims in Chicago, he said it’s different when it’s your own family.

“I get that phone call from sister asking me was I there. I told her, yeah, I’m on 67th Street, what’s the matter? She told me about my nephew,” he said. “I’m 10 feet away from the ambulance, and I’m headed toward the ambulance, and I’m trying to get them to stop, and they jetted off.”

Holmes said his nephew is a student and basketball player at Dunbar Career Academy High School in Bronzeville, but he does not know if his nephew has any gang ties.

“I don’t know if he’s affiliated with any gang, or guilty by association with any gangs, but that’s something as a family, if it is, we have to address and make sure he keeps going to school and keeps playing basketball,” he said.
