San Angelo (AP) -  A grand jury in West Texas will begin taking testimony next week in a criminal investigation of a polygamist sect raided earlier this year, according to newspaper reports.

The grand jury plans appeared to be revealed Friday in a filing that secured a temporary restraining order for the 16-year-old daughter of Warren Jeffs, leader of the Fundamentalist Church of Jesus Christ of Latter Day Saints.

The teenager's court-appointed attorney sought the order against sect spokesman Willie Jessop, who Natalie Malonis accused of intimidating and harassing her client. In her request, Malonis said prosecutors could not find the teenager Thursday and serve a subpoena compelling her appearance before a grand jury.

"I believe that (the girl) was avoiding service because of coercion and improper influence from Willie Jessop," the request stated.

The request was obtained by The Dallas Morning News and the Houston Chronicle.

State District Judge Barbara Walther signed the order, which prohibits Jessop from having contact with the girl. Jessop told the Chronicle the petition was "outrageous."

Meanwhile, a Texas Attorney General's Office spokesman declined to confirm whether witnesses have been called or say anything about the grand jury.

"Grand jury proceedings by law are secret proceedings and therefore we cannot and will not discuss issues surrounding those proceedings," Jerry Strickland said.

Malonis says Jessop had improperly influenced the 16-year-old in order to protect "the church's interests and the interests of certain influential male members." Malonis believes the girl was forced into a spiritual marriage at age 15.

Attached to Malonis' motion was a letter purportedly written by the girl to Walther in which the teenager accuses Malonis of making "derogatory statements about my religion and my family." She requested a new lawyer but was denied.

Jessop has accused Malonis of failing to serve the girl's interests and being biased against his church.

"She's trying to blame me for her client not liking her," Jessop said. "It shows her pathetic mindset. The only thing I ever did was try to get them together."

The teenager was one of the hundreds of children taken from the Yearning For Zion Ranch by Texas Child Protective Services in April because investigators believed they were exposed to abuse by FLDS members.
