Investigators from Wright County and the Delano Fire Department are working toward determining what caused a fire that damaged a shed at 9037 County Rd. 17 SE in Franklin Township early Wednesday. Property owner Thomas Lemmerman reported the fire at 5:54 a.m. Firefighters from Delano and Watertown extinguished the fire, and were on scene for about two hours. The amount of loss is still under investigation due to the large amount of tools and equipment in the shed. No one was injured and no other buildings were damaged.
