Authorities have returned to Beech Creek months after scaling back efforts in the search for missing Rogersville 5-year-old Summer Wells.According to Tennessee Bureau of Investigation (TBI) public information officer Leslie Earhart, the return is part of a planned search to take advantage of winter weather.Earhart says there are no new developments in the Summer Wells case, and the heavy police presence is part of the search effort as the colder season brings less foliage in the area.
