Bowling Green, KY – A building on the campus of Western Kentucky University has re-opened for classes after a fire over the weekend. Fire investigators believe as many as four fires inside Cherry Hall were intentionally set early Sunday morning. No one was hurt. The 70 year old building sustained a half million dollars in damage. The fires destroyed an inter-active classroom and several offices. Dean David Lee says Cherry Hall will close at 5:00 pm for the rest of the semester and classes will be re-scheduled.
