WHEATON, Ill. (November 1, 2012)--Prosecutors say Elzbieta Plackowska, 40, a suburban Chicago resident, stabbed her 7-year-old son 100 times and a 5-year-old girl about 50 times and slit both their throats because she was angry with her husband.
A DuPage County judge Thursday ordered Plackowska of Naperville, Ill., held without bond.
Prosecutor Robert Berlin says Plackowska gave investigators several stories about Tuesday's killings, but eventually said she killed her son, Justin, because she was angry that her truck driver husband left her alone to care for the child.
Berlin says Plackowska then killed the girl she was babysitting, Olivia Dworakowski, because the child had witnessed the attack on her son.
Plackowska didn't speak during Thursday's hearing other than to indicate she could not afford an attorney.
