About 6:45 p.m., Jovan Wilson was inside his home in the 5600 block of South Princeton when two people broke in, started arguing with the boy and then shot him in the head, according to Chicago Police and a statement from the congressman. He was dead at the scene.

According to Davis, the two people who broke in were a 17-year-old girl and a 15-year-old boy who pulled a gun.

“I grieve for my family,” Davis said. “I grieve for the young man who pulled the trigger. I grieve for his family, his parents, his friends, some of whom will never see him again.”

Jovan’s mother had just left to pick up food before the shooting, leaving the boy with his two brothers, ages 8 and 14; his 16-year-old sister, and an uncle, Davis said.

“What could have prevented this tragedy? Better education, more supervision after school activity. Better parenting,” Davis said.

No one was in custody early Saturday as Area South detectives investigate.
