SHEBOYGAN, WI (WHBL) - A Sheboygan Falls man is facing numerous charges after allegedly sexually assaulting a 16 year old girl and threatening to kill members of her family if she told. 44 year old Shawn Senkbeil is also facing drug charges after the investigation led to the execution of a search warrant at his mobile home, where officers located drugs, drug paraphernalia and a grow room with 8 marijuana plants growing. The victim told officers that Senkbeil had taken her to his home, where they smoked marijuana and he then groped her. She also said that three years earlier he sexually assaulted her in her home while her parents were away. Senkbeil was arrested Tuesday following a three-week investigation.
