An Illinois mom confessed to stabbing her 7-year-old son and a 5-year-old girl a combined 150 times, police said.
Elzbieta Plackowska, 40, told authorities she killed her son Justin, 7, to get attention from her husband, a long-haul trucker who is often away from their home in Naperville, Ill., 28 miles west of Chicago.
“She was unhappy in her marriage and didn’t feel she was being treated right… and felt that this would be a way to get back at her husband,” Sgt. Louis Cammiso of the Naperville police department told the Daily News.
After killing her own son, Plackowska admitted to turning the knife on Olivia Dworakowski, a five-year-old girl she routinely baby-sat, because she was the only witness of the first murder.
Officers found the children’s mutilated bodies, with their throats slit, and two dead dogs, in the little girl’s home around 10:15 p.m. on Tuesday. Police were called to the scene when Olivia’s mother, who trusted Plackowska to baby-sit her daughter that night, returned home to find the house locked and Plackowska’s car gone.
“It was a horrific scene,” said Cammiso.
Justin appeared to have been stabbed about 100 times. Olivia appeared to have been stabbed about 50 times. Two bloody knives were discovered: one in the kitchen sink and one in Plackowska’s car.
Plackowska, covered with blood, drove to a Catholic Church but found it closed. She then called and left a voicemail confessing that she had done something “very bad.”
Officers found Plackowska in a friend’s house nearby, where her older son was staying. She was taken to a hospital briefly for minor cuts and questioned by investigators. She concocted various explanations to evade blame.
“The first story was that an intruder entered the home and stabbed the children … then at one point she said that the devil killed the children, and saying that the children were possessed by the Devil. But she ultimately admitted that all of those stories were lies,” Cammiso said.
Plackowska was charged with two counts of first-degree murder and denied bail on Thursday. She is being held in DuPage County and is scheduled to appear in court Nov. 21.
Olivia was a student in the Indian Prairie School District and Justin was a student in the neighboring Naperville School District 203.
“Both of the school districts … implemented their school-crisis response plans, and this includes bringing in school counselors and social workers to be on site at the schools to address the needs of the students,” Susan Rice, director of communications for the Naperville School District, told the Daily News.
This is not the first time children were murdered in Naperville. In 1999, Marilyn Lemak was found guilty of drugging her three children to death.
“Again, in that case, the motive was to get revenge on her ex-husband – at that time – because he had divorced her,” said Cammiso.
Now the Naperville community is mourning an eerily similar loss.
“Having this many families affected by this tragedy has had a sobering, reflective and shocking effect on the community,” Rice said.
