Accused double-murderer must give saliva and hair samples for DNA tests

Accused double-murderer Elzbieta Plackowska must give saliva and hair samples for DNA tests, a DuPage County judge ruled Monday.

Prosecutors sought the samples from the former Naperville babysitter to genetically compare with hair and blood found last October in the home where she allegedly stabbed her 7-year-old son and a 5-year-old girl.

Judge Robert Kleeman agreed to let prosecutors obtain the genetic material after Plackowska’s court-appointed attorney didn’t object to the DNA tests.

Plackowska, 40, is charged with stabbing and slashing her son, Justin, and Olivia Dworakowski — the daughter of an acquaintance — while babysitting at the girl’s Naperville townhouse.

A bloody knife was found in the kitchen sink following the Oct. 30 killings, while a second knife — also stained with blood — was found in Plackowska’s car, authorities have said. Hair fibers were found on and near the children’s bodies in the bedroom where they were slain, authorities have said.

Plackowska allegedly told police she killed the children to try to drive “evil” out of them but later told authorities she committed the murders because she was angry with her husband.

Kleeman already has ordered Plackowska to undergo a psychological evaluation sought by prosecutors.

Plackowska is being held without bail in the DuPage County Jail.
