When they arrived, a relative had already gone inside the house and found two victims in a car parked inside the garage. They've been identified as 27-year-old Kholood Abu-Nada and 43-year-old James Emile.
The Cook County Medical Examiner says the cause of death for Emile was accidental carbon monoxide inhalation. The cause of death for Abu-Nada is still pending toxicology results.
