Illinois Mom Stabbed Two Children 150 Times, Prosecutors Say

7-year-old son and 5-year-old girl she was babysitting did not survive

A Chicago woman stabbed her 7-year-old son 100 times and a 5-year-old girl she was babysitting 50 times at the girl's Naperville home, prosecutors said Thursday morning in a bond hearing.

Elzbieta Plackowska, 40, was charged with two counts of first-degree murder in the stabbing deaths her son, Justin, and Olivia Dworakowski on Tuesday night in Olivia's suburban Chicago home. She was denied bail this morning during her first court appearance.

Plackowska told investigators several stories, at first blaming the attack on a stalker who got into her home in Naperville, 25 miles west of Chicago. She later said the children had evil inside of them and she was fighting the devil in the house, DuPage County State's Attorney Robert Berlin
