Rebecca Musser, 37, opens up about life in the polygamous FLDS sect, where, at 19, she claims she was forced to marry 85-year-old alleged prophet Rulon Jeffs. After she escaped the sect, Rebecca's testimony was instrumental in putting FLDS leader Warren Jeffs behind bars for life after being convicted of two felony counts of child sexual assault. How did she escape what she alleges was a life of abuse? And, why does her father, Lloyd, say she's spewing lies?
