Lake County officials are investigating the death of a Mundelein woman found Wednesday in her car in a Lake Zurich church parking lot.
Her case brings the number of blizzard-related fatalities to 11.
Susan Smith, 57, was missing for about 24 hours before she was found. Authorities are looking into whether she died from exposure to cold, the Chicago Tribune reports.
DuPage officials have linked four deaths to shoveling snow.
Chicago officials reminded residents in a press conference Thursday to take breaks while shoveling.
