William Jansen (1983 – ) was an LDS church member and police officer in Twin Falls, Idaho; accused of sexual abuse; pleaded guilty.

William Anthon Jansen “of Twin Falls faces four felony counts of lewd conduct with a minor under 16 and one misdemeanor count of disseminating material harmful to a minor…

“A teenage girl came forward with the allegations two weeks ago, saying Jansen sexually abused her in 2008 and 2009 when she was between 7 and 9 years old. She told the sheriff’s detective that Jansen also abused at least two other girls – one who has since died, and another who confirmed Jansen abused her when she was 8 years old, in 2005 and 2006… Jansen’s ex-wife told sheriff’s investigators Jansen admitted to “inappropriately touching juvenile girls” and to having sex with a 17-year-old roommate that lived with them while they were married. She also told investigators that Jansen was sent home dishonorably from his Mormon mission “due to a sexual incident that occurred.”… His ex-wife also told detectives Jansen disclosed to his Mormon bishop that “he had inappropriate contact with juveniles.””
