FOND DU LAC, Wis – State game wardens have joined an investigation into what’s suspected to be a large-scale deer poaching operation in eastern Wisconsin. Sheriff Ryan Waldschmidt of Fond du Lac said he was tipped to the operation in July and believes that poachers have been active in adjoining counties too. Waldschmidt asked the public to be alert to clues — gunshots overnight, vehicle shining deer, and deer carcasses with bullet wounds. Bucks, he said, would have the full head removed. The scope of the investigation is 200 square miles in Dodge, Fond du Lac and Washington counties.
