Five people, including three children, were hospitalized after a stabbing and fire in Chicago's Logan Square. The incident left one child in critical condition, with authorities investigating the link between the events.

Three children were found stabbed in a burning building in Chicago’s Logan Square neighborhood on the Fourth of July, sources told NBC Chicago. The blaze was first reported around 10 a.m. local time Friday in the 3600 block of West Palmer.

A source close to the investigation said the call came into 911 from a family member, who said the children's mother "snapped" and stabbed the children before starting the fire.
