The Daily Mail reports that authorities are investigating allegations that followers of polygamist leader Warren Jeffs, the self-proclaimed ‘prophet’ of a breakaway Mormon sect, are still secretly holding underage girls  for sexual purposes.  Jeffs is presently serving a life-plus-twenty sentence in a Texas prison for raping his own child wives, ages 12 and 15.  Earlier this week Jeffs reportedly banned all members of his 10,000-member congregation from having sex and declared all marriages void until he can return and ‘seal’ them.  Notwithstanding his life sentence, Jeffs reportedly expects to return to lead his flock.  Joni Holm, who has many relatives in the polygamous sect, told the Desert News that “[Jeffs] has predicted that the walls in the prison where he’s at will fall and crumble.”
