A Fond du Lac County judge sentences a man sentenced to life in prison for killing a go-go dancer more than three decades ago. 53-year-old Thomas Niesen of Ashwaubenon slashed Kathleen Leichtman's throat back in July 1976 and then dumped her body by the side of the road. Niesen was arrested in February after DNA linked him to Leichtman. Leichtman had come from Milwaukee to Fond du Lac to dance at The Other Place bar when she was killed.
