Waupun fire officials aren’t sure what started a fire that destroyed a car this week. Assistant Fire Chief Wayne Verhage says firefighters were called to the Walgreens parking lot to a report of a car on fire. Verhage says the driver had left the car idling in front of Walgreens while he ran into the store to grab a few items. When firefighters arrived the car was fully involved. Verhage says a passerby rescued a pet dog from the burning vehicle. Nobody was injured.
