Wausau authorities are holding a Tomahawk man for trying to meet what he thought was a 15-year-old girl so they could have sex. Forty-year-old Joseph Wagner is being held in the Marathon County Jail. Investigators say he sent several inappropriate videos and photos to the undercover officer posing as a teenager over a two-week period. When Wagner was taken into custody in Rib Mountain, condoms and lubricant were found in his vehicle.
