(HICKORY HILLS) An autopsy on Friday into the death of a pregnant southwest suburban woman has found she died of natural causes and not as the result of any domestic incident, as had previously been reported.

Police responded to the 7700 block of West 91st Place in Hickory Hills on Thursday after receiving a report of an unresponsive pregnant woman who had suffered from the flu for two weeks, according to Hickory Hills police Lt. Tim Stevens.

Margaret Jefferson, 38, was pronounced dead at 7:10 a.m. at Palos Community Hospital in Palos Heights and her child, who was delivered stillborn, was pronounced dead at 1:14 p.m., according to the Cook County Medical Examiner’s office.

Jefferson had suffered from the flu for at least two weeks, authorities said. It was believed she died from pulmonary embolism, which is common among pregnant mothers suffering from the flu, Stevens said.

Early rsults of a Friday autopsy showed she died of natural causes, police said.

There was no history of domestic violence at Jefferson’s home, and her body did not suffer any trauma, Stevens said.
