Justin Plackowski's wake is scheduled for Nov. 5 at 3 p.m. at St. Elizabeth Seton Church in Naperville, Scott Elementary School says. Funeral services scheduled for Tuesday morning at 10 a.m. will be held in the same location.

Prosecutors say Plackowska admitted to killing her son and another girl out of anger at her husband. Officials say Plackowska ordered Justin and 5-year-old Olivia Dworakowski, who she was babysitting, to kneel on a bedroom floor and pray. She then stabbed them both dozens of times as they begged for their lives, striking again and again as she told her son he was going to heaven.

Plackowska arrived in the United States from her native Poland on a tourist visa 12 years ago, Berlin said. She is not a U.S. citizen and authorities were trying to verify her immigration status. Berlin said she has no prior history of violence, although she had a misdemeanor DUI about 10 years ago.

She has been charged with first-degree murder in the children's deaths.

Naperville is a populous suburb 25 miles west of Chicago.
