Since March 30, Jessop has received a flood of phone calls from "Sarah," who she said spoke like a little girl and seemed to know the intricacies of life in the FLDS Church and Short Creek, the FLDS strongholds of Hildale, Utah, and Colorado City, Ariz.

"She was damn good," Jessop said of the girl. "She had the 'crick' lingo down, which is just amazing."

Others were convinced that "Sarah" needed help.

"I thought she was real," said Joni Holm, who shelters FLDS kids and also spoke to the girl.

The conversations would last for hours. "Sarah" said she wanted to run away, and provided details of a life of abuse. "Sarah" gave her addresses of where she said she was inside the FLDS stronghold of Colorado City, Ariz. Jessop reported the calls to child welfare workers, who checked out the homes and found nothing. The calls continued, always from different cell phone numbers.

Eventually cracks started appearing in the girl's story.

"She did not use the term 'mother and father.' She used the term 'mom and dad,"' Jessop said. "There were just numerous things, but still she was very convincing as a girl that was in desperate need of help."

Jessop said when she pressed "Sarah" once, the girl claimed to talk in hypotheticals about a twin sister who was also a child-bride. The story started to make Jessop more suspicious, and she began tape recording them and called police.

Jessop said she set up a three-way phone conversation with a Texas Ranger on the line and confronted her.

"By the end of my phone calls with her it was very, very difficult to continue to talk to her and not reach through the phone and choke her," she said. "I asked her, 'Are you tricking me?' I said, 'What's your real name?' She finally said, 'Rozie."'

By that time, authorities had tracked Swinton down in Colorado Springs and Texas Rangers told local officers they were coming to question her.

"They had independently focused one component of their investigation on her and were coming up to our city. We then brought our case to a conclusion, made the arrest and assisted Texas while they were here," said Colorado Springs Police Lt. Skip Arms. "They will evaluate what they have to determine if they'll pursue any charges in the future."

The affidavit dealing with the February incident in Colorado Springs has been sealed by a judge, but Arms said it involved her making calls to police of a "distress nature."

Colorado police have dealt with her in the past, Arms said, and authorities have even come to recognize some calls from her. This is the first time, however, that she has been charged with any crime.
