The girl, who said she was several weeks pregnant and the mother of an 8-month-old infant, requested assistance leaving the ranch, which is owned by the Fundamentalist LDS Church. The affidavit states that the girl called several times that day, expressing the "need to leave her current living situation." During the phone calls, the girl told shelter workers she was using someone else's cell phone and spoke quietly so she would not be overheard and "get in trouble," the affidavit states.

The teen told officials she had been taken to the ranch by her parents about three years ago. Then, last year, when she was 15, she was "spiritually married to an adult male member of the church." He was 49, and she became his seventh wife.

The teenage mother said she began to be abused shortly after she started living at the ranch. "She advised that the adult male would 'beat and hurt her' whenever he got angry," according to the document.

This included hitting her in the chest and choking her, the affidavit states. When such abuse occurred, the girl told officials, other women in her home would hold her infant child.

The last time he beat her was on Easter Sunday, she said. The document also indicated that the man had once beaten her so severely that she suffered several broken ribs.

After that incident, she was taken to a hospital, and a doctor wrapped her torso with a bandage and told her, "Take it easy for a few days," according to the document.

The girl also said the man would force himself on her sexually.

She told officials she was never allowed to leave the ranch except for medical care. In such cases, a man would drive and another woman from the ranch would accompany her.

The young mother said she tried to come up with a plan to escape by pretending to be sick, the document says. She then realized that wouldn't work because she wouldn't be able to take her baby with her unless the infant also was ill.

The girl also said, according to the affidavit, that "her parents did not live on the YFZ Ranch and that she has not had any contact with them to explain that she does not want to continue to be on the ranch."

The next day, on March 30, the same girl called the family shelter again, the documents state. She again mentioned her "spiritual union through the church," but said there had been no formal marriage. She said her husband, who had three other wives living on the ranch, had left the compound to the "outsiders' world."

The department of family services determined the man had been indicted in Mohave County, Ariz., on criminal sex charges in connection with a purported marriage to a minor there. The document said the man was convicted and sentenced to 45 days in jail and three years' probation. The document didn't mention his name, but search warrants listed the name of Dale Barlow, who faced those charges and received the same sentence in Arizona.
