Barzee, who along with Mitchell had belonged to the Church of Jesus Christ of Latter-day Saints, said he manipulated her religious beliefs to get her to go along with the kidnapping. She testified that he had claimed to have had a divine revelation years earlier that God wanted him to take multiple brides.
Smart's testimony lasted for three days, but much of the trial was taken up by dueling experts discussing whether Mitchell was mentally competent.
Smart calmly sat through much of the trial, though she and her mother stormed out of court when one state psychiatrist testified that she had picked out baby names during her captivity in case she became pregnant.
After the verdict, however, Smart and her parents spoke triumphantly to a crush of reporters.
"This is an exceptionally victorious day for all of us," said Lois Smart, Elizabeth's mother.
Elizabeth Smart, who is on a break from her Mormon mission in France, said she hoped other victims of sex crimes and abductions would take heart from the verdict. "We can speak out," she said, "and we will be heard."
Until Mitchell's trial, Smart had remained largely out of the public eye and embarked on her mission work in Europe.
But last year she appeared on CNN to offer advice to Jaycee Lee Dugard, who was discovered 18 years after being kidnapped from South Lake Tahoe.
"I would just encourage her to find different passions in life and continually push forward and learn more and reach more for them," Smart said, "and not to look behind, because there's a lot out there."
