A Chicago woman is now facing charges after her 4-year-old son was killed and two other children were injured in a stabbing and arson fire on the Northwest Side, police said.

A woman was charged with stabbing three children, killing a 4-year-old boy, and setting a home on fire in Logan Square last week.

According to police, the 4-year-old boy sustained a stab wound to the chest and was taken to an area hospital where he was pronounced dead.
