On Friday night, buildings on the north side of the Darke County Fairgrounds were destroyed by fire. Eleven nearby fire departments were called to battle the three-alarm blaze and one firefighter was hurt. Witnesses say the beef building looked to be a total loss. The dairy had some damage and the hog barn may only have exterior damage and was been saved by the quick work of the multiple fire departments. We will provide more information as it becomes available. A full investigation continues.
