A fire at a building on South Harrison, about a half block from Main Street, has fire investigators calling it arson. The fire bell rang just past dinner time last night, and when crews got to the place, they saw smoke coming out the windows. Once they got inside, the building’s sprinkler system was going off and they found the fire on the 2nd floor, and were able to get it out in short order.  Investigators were called in and say this was arson and they want your help.  If you saw anything that seemed out of place at about 6 last night, call the guys from Crime Stoppers.
