ELDORADO, Texas -- Some of the 437 children of a polygamous sect are being taken to temporary foster care facilities around Texas, state child welfare officials said on Tuesday.

At the same time, authorities were taking DNA samples from sect members to sort out the children's ties to parents in the close-knit sect.

Lawyers inside the San Angelo Coliseum where the children had been housed for more than two weeks said Children's Protective Services representatives set up tight security and no one was allowed in or out of the coliseum while the children were loaded on to buses.

Five locations in San Antonio have been designated for receiving children: Baptist's Children's Home, The Children's Shelter, St. Peter-St. Joseph Children's Home, Boysville and Seton Home, according to court documents obtained by TV station KSAT.

The station reported that the children being moved are those who have completed DNA testing. About 100 children ages 5-17 have been sent from San Angelo to various points throughout the state, KSAT reported.

State district Judge Barbara Walther had signed an order earlier Tuesday allowing the state to begin moving the children into temporary foster care facilities -- group homes or other privately run facilities -- until DNA testing is completed and individual custody hearings can be completed by June.

CPS representatives declined to comment on the move.

Last week, a judge ordered that the DNA be taken to help determine the parentage of the children, many of whom were unable to describe their lineage.

Some of the adults have been ordered by the state to submit to testing, while others are being asked to do so voluntarily.

One of the attorneys for the sect worries that authorities have another motive for taking DNA samples from adult church members, fearing they could also be used to prosecute adult church members for abuse.

Rod Parker of the Fundamentalist Church of Jesus Christ of Latter Day Saints wonders whether authorities secretly intend to use the DNA to build criminal cases.

A spokesman for Texas Child Protective Services denied that's the objective.

Authorities said they believe the sect forces underage girls into marriages with older men.

Authorities said they need to figure out the complicated family relationships before they begin custody hearings to determine which children may have been abused and need to be permanently removed from the sect compound.

For now, no charges have been filed.
