(AP Photo/DuPage County Sheriff's Department) A chilling case out of Illinois: A woman fatally stabbed a 5-year-old girl she was babysitting and her own son, age 7 or 8, reports the Chicago Tribune. Elzbieta Plackowska told police that demonic voices in her head commanded her to save the kids' souls from the devil by stabbing them numerous times to death Tuesday night. Two dogs were also found stabbed to death in the home. Afterward, she drove to a church to try and find help, then showed up at her adult son's home, covered in blood. It's a haunting reflection of the recent murder in NYC. Plackowska is in police custody and has been charged with two counts of first-degree murder. She's scheduled to appear in bond court today.
