Warren Jeffs was convicted Thursday of sexually assaulting two child brides after a whirlwind trial in which the polygamist sect leader insisted on representing himself, only to remain silent through much of the proceedings and present just one witness – a church elder who gave an extended Sunday school lesson on its beliefs.

The tall and lanky head of the Fundamentalist Church of Jesus Christ of Latter Day Saints stood stone-faced as a verdict of guilty on two counts of sexual assault of underage girls was read, after the jury of 10 women and two men deliberated for 3 hours. He had stood mute during his closing argument, staring at the floor for all but a few seconds of the half hour he was allotted.
