Prosecutor: Naperville, Ill., murder suspect told children to pray WHEATON, Ill., Nov. 1 (UPI) -- A Polish immigrant allegedly told her son and a second child to pray before she fatally stabbed them, an Illinois prosecutor said Thursday. DuPage County State's Attorney Robert Berlin described the killings during a hearing, the Chicago Tribune reported. A judge ordered Elzbieta Plackowska held without bail. Police found the bodies of Justin Plackowska, 7, and Olivia Dworakowski, 5, in Marta Dworakowski's Naperville townhouse late Tuesday. Dworakowski had been working an evening shift as a nurse while Plackowska looked after Dworakowski's daughter. Plackowska ordered Justin and Olivia to kneel, Berlin said: "She told Justin and Olivia to get on their knees and pray. She told Justin he was going to heaven tonight. Police found Plackowska at another home in Naperville, 20 miles west of Chicago, the Chicago Sun-Times reported. A resident of the area told the newspaper the house belonged to a friend of the alleged killer. Plackowska was described as upset after her father's death. She allegedly told police she was angry at her husband, a truck driver who was often away from home, and wanted to move back to Poland. She said she took the children to St. Elizabeth Seton Church before the killings. Police said both children were stabbed repeatedly, Justin 100 times or more and Olivia, 50, the Tribune reported. Prosecutors said the little boy pleaded with her not to kill him.
