The scene was turned over to the fire investigator who determined the fire was caused by a block heater cord plugged into an extension cord.
The cord had been pinched from the hood of the vehicle being closed and compressing it – the fire started in the hood area of the vehicle.
Damage from the fire is estimated to be $60,000.
