Prosecutor says Illinois woman stabbed son 100 times

NAPERVILLE, Ill. — A suburban Chicago woman stabbed her 7-year-old son 100 times then turned the knife on a 5-year-old girl who witnessed the attack, killing both as they begged for their lives, a prosecutor said Thursday.

Elzbieta Plackowska, 40, told investigators she stabbed the children and slashed their throats Tuesday night at a ­Naperville home because she was angry that her truck driver husband was often away, ­DuPage County State’s Attorney Robert Berlin said.

‘‘She told the detectives that she thought by killing [her son] Justin she would make her husband hurt the way she hurt in their relationship,’’ Berlin said.

Plackowska told investigators she found Justin and ­Olivia Dworakowski — whom she was baby-sitting — jumping on the bed, Berlin said.

‘‘She had grabbed the knife and she made both victims kneel and begin praying. She began stabbing her son, Justin, and told him he was going to heaven tonight. He pleaded for his life and told her to stop,’’ he said after the hearing.

‘‘She then turned her attention to 5-year-old Olivia and began stabbing her. ’’

The slayings took place at the home of Olivia’s mother, who works nights as a nurse.

After the killings, Plackowska tried to go to a church but found it closed, Berlin said.
