Idaho State Police have issued an Amber Alert for two missing Idaho teenagers, who are believed to be headed to a Fundamentalist Church of Jesus Christ of Latter-Day Saints group in Mendon, Utah.

Allen Larand Fischer, 13, and Rachelle Leray Fischer, 15, were reported missing June 22 from Monteview, Idaho.

The Fundamentalist Church of Jesus Christ of Latter-day Saints is a polygamist sect run by Warren Jeffs, the self-proclaimed prophet and convicted pedophile. In 2011, Jeffs was convicted on two counts of child sexual abuse and sentenced to life in prison.
