Salt Lake City, Utah (CNN) -- Elizabeth Smart has long been silent about the details of an ordeal that began in June 2002 when a stranger crept into her bedroom, held a knife to her throat, marched her up a hillside trail and made her his sex slave. She has spoken to local groups about how to move on after a traumatic experience, celebrated the passage of a national Amber Alert law for missing and abducted children, and offered advice to another alleged kidnapping victim, Jaycee Dugard. In October 2009, Smart drew a general outline of her experience at a hearing to determine whether her accused captor, Brian David Mitchell, 57, was mentally competent to stand trial. Much of her testimony focused on Mitchell's ability to manipulate people and talk his way out of a jam.
