Some of the phone calls to an abuse hotline in Texas that sparked one of the largest child-custody case in U.S. history came from a cellphone previously used by 33-year-old Rozita Swinton of Colorado Springs, court documents confirmed today.

Some 437 children were seized in raids that began April 3 at a Texas ranch owned by the Fundamentalist Church of Jesus Christ of Latter Day Saints, after a caller claimed to be a pregnant 16-year-old sect member who was being held and abused. The girl has not yet been found.

According to the affidavit, Texas authorities contacted Colorado Springs police on April 13 asking about two Colorado Springs 719 area code phone numbers that were related to the calls that sparked the YFZ (Yearn For Zion) raid. One of those two numbers was connected to other cases involving Swinton.

The affidavit released today also lays out more than a half-dozen phony reports connected to Swinton since 2005. Swinton has a history of making prank calls and false police reports, according to the affidavit, including claims in October to have been sexually abused by a pastor at New Life Church in Colorado Springs and, in another case, that she was a 13-year-old girl being abused by her father with sex and drugs in Colorado Springs.

The Texas hot lines received calls from a woman claiming to be “Sarah Barlow” both before and after the raid on the YFZ ranch.

Before the raid, she claimed she was being abused by her 49-year-old polygamist husband, Dale. In one of the calls made after the raid, “Sarah” claimed “sisterwives” from the compound said workers at the shelter where the sect members were being held were trying to poison them with “food in shiny wrappers.”

Rangers were present when Swinton was arrested April 16 by Colorado Springs police on what has been described as an unrelated false-reporting charge in the city.

A search warrant for telephone records showed Swinton also had called abuse shelters in Washington, Utah, Arizona and Florida.

In February 2007, she told Longmont and Pueblo police in separate calls that she was a 15-year-old mother who was being abused by her uncle.

She faked out Castle Rock police in 2005, claiming to be a suicidal teen with a newborn, which led to an arrest and conviction in Douglas County. She received a one year deferred sentence.

Swinton has been released from El Paso County Jail on a $10,000 bond on the misdemeanor charge. She has not been charged in the Texas case but has been identified as a “person of interest” by Texas authorities. She has since gone into hiding.

A roommate at her apartment told The Post last week that Swinton was unmarried with no children and holds a steady job working for an insurance company.
