Salt Lake City ? Prosecutors charged a self-proclaimed prophet and his wife Tuesday with aggravated kidnapping and sexual assault in the abduction of Elizabeth Smart, disclosing for the first time details of the girl’s nine-month ordeal.

Brian Mitchell and Wanda Barzee also were charged with burglary and attempted aggravated kidnapping — a charge stemming from what prosecutors said was an attempt to later abduct Elizabeth’s 18-year-old cousin.

“We are not dealing with just a religious zealot, we are dealing with a predatory sex offender,” Dist. Atty. David Yocom said in announcing the charges.

Mitchell, 49, and Barzee, 57, could receive life in prison if convicted. They were scheduled to be arraigned today, and bail was set at $10 million each.

Before Tuesday’s charges, no details had been released about any abuse Elizabeth, now 15, might have suffered during her disappearance.

Prosecutors contend Mitchell, a drifter whose writings promote polygamy, entered the Smart home June 5 after using a knife to cut a window screen. Elizabeth, dressed in pajamas, was forced at knifepoint to walk four miles up a mountain trail behind the Smart family home to a concealed campsite, according to court papers.

Mitchell threatened to harm or kill the girl’s family members if she resisted, the papers said.

“She was under the threat of death,” Yocom said.

Lois and Ed Smart, parents of Elizabeth Smart, leave the county building after meeting in the district attorney's office in Salt Lake City. Charges were filed Tuesday against Brian Mitchell and Wanda Barzee in connection with Elizabeth's kidnapping last June.

Prosecutors said that when the trio reached the campsite, Barzee tried to remove Elizabeth’s pajamas. When the girl resisted, Barzee threatened to have Mitchell forcibly do it, they said.

Mitchell then “raped or attempted to rape her, or commit forcible sexual abuse against her,” with Barzee’s help, Yocom said. At some point, the girl was restrained with a cable around her foot that was tethered to a tree, he said.

The couple held Elizabeth against her will at the campsite until Oct. 8 with little or no shelter, water or food, prosecutors said. They then took her to California, where they stayed until March 5, according to the court papers.

Elizabeth was found with the couple on March 12 in Sandy, a Salt Lake City suburb.

Attorney Larry Long, who initially claimed to represent Mitchell, said Mitchell told him that he considers Elizabeth his wife and that her disappearance was a “call from God” — not a kidnapping.

Yocom said Mitchell had told him that Long wasn’t his attorney “and had no authority to speak for him.”
