The Sturgeon Bay Police Department is responding to concerns raised about the use of videos from hidden bathroom cameras at a downtown book store. Thirty seven year old Steven Link and 26-year old Kory Murphy, both of Sturgeon Bay, face federal charges related to possession of child pornography. As part of the investigation, videos reportedly taken of people of all ages using the bathroom facilities turned up. Captain Dan Brinkman says while the investigation is ongoing, there is no evidence at this point to suggest that any of the video recordings of those using the bookstore bathroom were distributed to others. Brinkman also says the matter is proceeding through the federal system and Sturgeon Bay Police are unable to field any further questions regarding the case.
