The attorney representing a Naperville woman accused of stabbing her young son and a young girl she was baby-sitting for in 2012 said he is preparing an insanity defense for the woman.

Assistant Public Defender Michael Mara said Tuesday he filed a "Notice of Affirmative Defense -- Insanity" for Elzbieta Plackowska.

He also filed a supplemental disclosure identifying the two doctors who wrote the defense's report.

No trial date has been set but Plackowska will not contest the charges.

Plackowska, 43, is accused of repeatedly stabbing Olivia Dworakowski, 5, and her own son, Justin Plackowski, 7, on Oct. 30, 2012. Police said she killed them while baby-sitting at the younger child's home.

Plackowska told investigators she killed her son to get back at her husband and Olivia because she was a witness, according to prosecutors.

If Plackowska is found to be not guilty by reason of insanity, she could be confined to a state mental hospital. If found guilty and sane, she could be sentenced to natural life in rather than prison.

Plackowslka's case is next scheduled for May 27 to give prosecutors time to review the reports Mara filed.
