WHEATON, Ill. - Prosecutors say a suburban Chicago woman 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 on Thursday ordered 40-year-old Elzbieta Plackowska of Naperville held without bond.

   Prosecutor Robert Berlin said 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 said 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.
