DuPage County prosecutors filed a request to have Naperville babysitter Elzbieta Plackowska, who is accused of stabbing to death her 7-year-old son and a 5-year-old girl, undergo a psychological evaluation, according to the Chicago Tribune.

Judge Robert Kleeman did not make a ruling during a court hearing on Thursday, but ordered that Plackowska and prosecutors return to court on Tuesday, the Chicago Tribune reports. 

Prosecutors said 40-year-old Plackowska told her 7-year-old son Justin and 5-year-old Olivia Dworakowski to get on their knees and pray before fatally stabbing both children nearly 100 times.

On the night of Oct. 30, when Plackowska was brought in for questioning after the murders, she told police that the children had evil inside of them and she was trying to get the evil and devil out of them.
