Chicago police are responding to a mass shooting in the River North neighborhood Thursday morning.
Police said the boy was playing video games at the time.
Sticking close to her parents, the 7-year-old smiled shyly in her pink unicorn hat and barely uttered a word as her parents recalled the events.
Families were still trick-or-treating in the area despite the heavy police presence.
The women were both mothers of four who worked with Mothers Against Senseless Killings to stem violence.
A judge denied bail for two men charged in the murder of a young mother who was holding her 1-year-old baby.
