A preliminary investigation indicates a fire that destroyed a barn in Fond du Lac County this week may have been electrical in nature. Firefighters from 20 area departments responded to the fire on Pine Road in the town of Eden Tuesday afternoon and found the barn fully engulfed in flames. Fond du Lac County Sheriff’s captain Bill Tadych say while an official cause has not been determined, initial indications point to an electrical problem because there were fans being used in the barn when the fire started. Tadych says , in general, it doesn’t take long for barn fires to spread. An undisclosed number of cattle died in the fire.
