Shortly after midnight Thursday Monroe, Stevenson and Stepney Volunteer Fire were called to lower Barn Hill Road for a barn fire. The 4-stall, 2-story barn and surrounding storage piles were heavily involved in flames with a significant fire load inside. Monroe and Shelton crews had to work for three hours to fully extinguish the fire.  No one was injured and no animals were involved. EMS and police provided support on scene.   The cause appears unintentional and is under investigation by the fire marshal.
