Mormon fundamentalist leaders

Warren Steed Jeffs is an American cult leader and convicted child sex offender. He is the president of the Fundamentalist Church of Jesus Christ of Latter-Day Saints, a polygamous cult based in Arizona and is serving a life sentence in Texas for child sexual assault after two convictions in 2011. The FLDS Church was founded in the early 20th century when its founders deemed the renunciation of polygamy by the Church of Jesus Christ of Latter-day Saints to be apostasy. The LDS Church disavows any connection between it and the FLDS Church, although there are significant historical ties.
