A fire gutted a mobile home trailer used as an office for Screeners Landscape Supply in Putnam Township Thursday afternoon. Chief Greg Amburgey of the Putnam Township Fire Department said the first crew to arrive on scene to the sand and gravel company located at 110 Swarthout Drive at the corner of D-19 saw “light smoke, light fire.” “The gate was locked, trailer was locked (and) nobody was here,” he said. “We had to force entry in the building to get to the fire.” It took firefighters a few minutes and less than 500 gallons of water to extinguish the flames.
