Authorities in Ashwaubenon report no injuries in a roof collapse caused by heavy snowfall Sunday morning.  Nobody was in the enclosed pool area at about 10:00 A-M when that roof gave way at the EconoLodge.  Ashwaubenon Public Safety Chief Eric Dunning says a 40-foot section of the roof fell in after a snowstorm dropped more than 15 inches of snow on the area.  It hasn’t been confirmed that the snow caused the problem.  Sixty-five guests of the hotel were relocated to more lodging nearby.  Shortly after that incident, the roof of another building in the Ashwaubenon Business Park collapsed.0
