Warren Jeffs' Kids Say He Molested Them New accusations against the polygamous Mormon sect leader By Michael Harthorne, Newser Staff Posted Sep 29, 2015 1:58 PM CDT 60 comments Comments Warren Jeffs (AP Photo/Trent Nelson, Pool, File) (Newser) – Two adult children of imprisoned, polygamous Mormon sect leader Warren Jeffs tell CNN Jeffs sexually abused them as children. Becky and Roy Jeffs recently left the 10,000-member Fundamentalist Church of Jesus Christ of the Latter-day Saints; two of Jeffs' other children have done the same. Becky Jeffs tells CNN one of her sisters also said she was molested as a child. "I thought, I'm not the only one molested, he's done it to her it must be something that was in his nature," she says. "Where does it end? If he had this in him, how can I trust him? How is he really our prophet?" "One of my earliest memories is of him sexually abusing me," Roy Jeffs says. "I was about four or five years old ... I remember him telling me, 'You should never do this.' And then he did it to me." Becky Jeffs says she sometimes thinks her father may have molested "10, 20" children. Warren Jeffs was convicted in 2011 of sexually assaulting two young girls who he called his "spiritual wives," CNN reports. He's serving a life sentence while continuing to serve as head of FLDS. He has approximately 60 children by approximately 78 wives.
