Nearly a week after he was convicted of two counts
of child sexual abuse, polygamist leader Warren Jeffs was sentenced to life in prison Tuesday.
Jeffs, 55, was characteristically silent as the San Angelo, Texas, jury's verdict was read, reports the Associated Press.
According to prosecutors, Jeffs engaged in sexual abuse with two girls ages 12 and 14. A key piece of evidence against him was an audio recording of Jeffs having sex with the 12-year-old.
The trial turned into a spectacle when Jeffs decided to represent himself in court. He said he was "at peace" at last week's summation following his conviction.
Jeffs considers himself the prophet and leader of the Fundamentalist Church of Jesus Christ of Latter Day Saints, an offshoot banned by the Mormons, which requires men to have three wives to be admitted to heaven.
