An Oak Lawn man is charged with shaking his 8-year-old daughter, leading to her death, officials said.
An autopsy performed Wednesday morning determined that the infant had died of injuries from abuse. His death was ruled a homicide, according to Oak Lawn police.
Edward Janiszewski has been charged with first-degree murder, police announced Wednesday evening. Janiszewski was initially charged with one count of aggravated assault and battery on a child.
Officers responded to a report of a baby with severe head and brain injuries on June 2 at Hope Children’s Hospital.
Staff told police the child was originally brought in on May 27 with what was thought to be a stomach illness and dehydration, police said.
The child was taken back to hospital unresponsive on May 30. Staff diagnosed the child with brain trauma consistent with the baby being shaken, police said.
The baby was pronounced dead Sunday at the hospital, the Cook County Medical Examiner’s Office said.
Detectives interviewed Janiszewski who admitted to shaking the baby and banging her head on a cushion early in the morning of May 30, police said.
He appeared in court Saturday on charges of aggravated battery and posted bond, police said.
He is due in court on Friday.
