New Milford High School students were briefly evacuated yesterday because of an odor in the building.  Superintendent Alisha DiCorpo later received an update from the Facilities Director that the building has been cleared by the fire department and that students and staff were able to return.  It was confirmed by the fire department that a bad internal bearing in the motor of an air handler created the smell that was carried throughout portions of the second floor. Back in December, New Milford High School was evacuated due to a roof construction fire.  The school was closed for two days at that time.
