A 71-year-old woman was found dead inside a vehicle Wednesday in Jefferson Park on the Northwest Side.
About 6 p.m., officers responded to a call of a person slumped over the wheel of a vehicle left running in the 5200 block of North Elston Avenue, Chicago police said.
They found the unresponsive woman inside, and she was pronounced dead at the scene, police said.
An autopsy released Thursday determined she died of natural causes, according to the Cook County medical examiner’s office.
Area North detectives were conducting an investigation pending a ruling from the medical examiner’s office.
