There were a series of suspecious fires early this (Friday) morning. The first happened just after midnight on Factory Road, which is off Halls Hill Pike near Kittrell. The first fire was in an abandoned mobile home. While the firefighters battled that blaze, another vacent home a short distance away was reported "on fire." It took nearly 50 volunteer firefighters to put out both fires. To make matters worse, while fighting the second fire, there was at least an attempt to start a fire at a third location. That fire was extinguished quickly. Rutherford County Fire Chief Larry Farley says arson investigators are looking into these suspecious fires.
