A San Antonio jury has found polygamist leader Warren Jeffs guilty on both sexual assault charges on Thursday.

The 55-year older leader of the Fundamentalist Church of Jesus Christ of Latter Day Saints was charged with sexual assault of a child after taking a 12-year old girl and a 15-year girl as "spiritual wives."

He could be sentenced to up to 119 years in prison.

The jury's decision puts an end to a controversial case that saw Jeffs represent himself against the charges. Jeffs largely avoided defending himself during the case, only offering a "I am at peace," phrase as his closing statement.

The jury made its decision on the same day that the prosecution played a tape recording of what it alleged was Jeffs sexually assaulting the 11-year old girl.
