Was Elzbieta Plackowska of Naperville sane the night she is alleged to have killed two young children, including her 7-year-old son?
The answer may be contained in a 900-page psychologist's report that emerged from a 15-month evaluation of Plackowska ordered by DuPage County State's Attorney Bob Berlin.
Berlin submitted the report to Judge Robert Kleeman and Plakowska's defense attorney Friday but declined to comment on its contents.
Prosecutors can request a psychological screening of a defendant when they have reason to believe insanity might be raised as a defense. Plackowska's lawyer also can seek an independent exam.
Defense attorney Michael Mara asked for an opportunity to review the report and was given until March 7.
The 41-year-old woman is accused of repeatedly stabbing Olivia Dworakowski, 5, and her own son, Justin Plackowski, 7, in October 2012. Police said she killed them while baby-sitting at the younger child's home.
Plackowska remains jailed without bail and has pleaded not guilty.
