In September, a jury found that Warren Jeffs, 51, used his authority as leader of his religious sect to force a then 14-year-old girl to marry and then have sexual relations with her 19 year-old first cousin, CBS News correspondent Steve Futterman reported.
The sentences are to be served consecutively. It will be up to the Utah parole board to decide just how long he stays behind bars. The average for Utahns convicted of rape or other first-degree felony sex offenses is seven years, said Jim Hatch, a state parole board spokesman.
Since his capture 15 months ago, Jeffs has been held in jail, where he has attempted suicide and told his flock that he is not their prophet.
Jeffs is head of the Fundamentalist Church of Jesus Christ of Latter Day Saints, whose members practice polygamy in arranged marriages that have often involved placing young girls with older men. Most FLDS members live in the twin communities of Hildale, Utah, and Colorado City, Ariz., about 350 miles southeast of Salt Lake City.
Washington County prosecutors said Jeffs enticed Elissa Wall into marriage and sex against her will by telling her the relationship was commanded by God and that any refusal would place her salvation at risk.
Jurors said Wall's age was a major factor in their decision. Under Utah law, a 14-year-old can consent to sex in some circumstances. But it is not considered consensual if a person under 18 is enticed by someone at least three years older.
Wall, now 21, testified that Jeffs failed to help her when she protested the marriage and when she later asked for a divorce because she was uncomfortable having sex with Allen Steed.
Steed, now 26, told a different version of events. He said Wall initiated sex and denied that she had cried during their wedding ceremony.
Weeks after the Sept. 25 verdict, the judge unsealed court documents that disclosed a suicide attempt by Jeffs in jail. He apparently attempted to hang himself in January, months before trial. Authorities have declined to discuss the incident, although Jeffs was taken to a hospital for just a few hours.
The documents also included selected jail transcripts of phone calls and visits between Jeffs and members of his church. Although he has been president, or prophet, since 2002, following the death of his father, Rulon, Jeffs said in jail that he had not been worthy of the "priesthood" for decades.
"I was immoral with a sister and a daughter when I was younger, so the Lord showed me I'm one of the most wicked men on the face of the Earth since father Adam's time," Jeffs said.
He never elaborated on the immoral acts.
The Associated Press does not typically identify people who allege sexual abuse, but Wall has made several public statements about the case using her maiden name. Citing safety concerns, she and her attorneys have declined to disclose her current legal name. Wall was granted an FLDS divorce by Jeffs after she became pregnant with another man's child; she left the faith and is married.
Steed was charged with rape the day after Jeffs' conviction. His case is pending.
Jeffs faces similar criminal charges in Arizona.
The mainstream Mormon church, the Church of Jesus Christ of Latter-day Saints, renounced polygamy more than a century ago, excommunicates members who engage in the practice and disavows any connection with the FLDS church.
