William Jansen Mormon Sex Crime Case Summary

04/11/06 Twin Falls,


LDS 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.””
