Double-murder suspect Elzbieta Plackowska of Naperville has been ordered to provide hair and saliva samples for DNA comparison.
Prosecutors want to test the samples against evidence found at the Naperville home where Plackowska’s 7-year-old son and a 5-year-old girl left in her care were stabbed to death in October.
According to court records, police found a blood-soaked knife inside the home and strands of hair in the hands of victims Justin Plackowski and Olivia Dworakowski.
At a hearing Monday, DuPage County Judge Robert Kleeman granted a motion by prosecutors requiring Plackowska to submit to DNA testing. The defense did not object.
Plackowska, 40, returns to court March 22.Copyright © 2014 Paddock Publications, Inc. All rights reserved.
