Warren Steed Jeffs is an American cult leader who is serving a life sentence in Texas for child sexual assault following two convictions in 2011. He is the president of the Fundamentalist Church of Jesus Christ of Latter-Day Saints, a polygamous cult based in Arizona. 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 apostate. The LDS Church disavows any relation between it and the FLDS Church, although there are significant historical ties.
