SAN ANGELO, Texas — As children from the Fundamentalist LDS Church settled into new foster homes this weekend, the whereabouts of two young boys remains uncertain.

Child welfare workers in Texas say they're not worried. But the mother of the boys and attorneys representing the mothers are not sure whether they should be or not.

"We just don't know where they are," Cynthia Martinez told the Deseret News Saturday.

Martinez, the communications director for Texas RioGrande Legal Aid, which represents 48 FLDS mothers, said they had information on where the boys were supposed to be taken but can't confirm anything to emotional parents. It's indicative, she said, of the fear and confusion the parents of the 467 children taken from the YFZ Ranch continue to feel.

Meanwhile, an FLDS member sent a letter to the governor of Texas on Saturday, accusing child welfare officials of "some of the most horrific violations of human rights that have ever been allowed on American soil."

The letter was sent to Texas Gov. Rick Perry from Willie Jessop, an FLDS member who has helped church members publicize their cause. The letter asks the governor to respond and "stop this injustice and abuse" of the innocent FLDS children by separating them from their mothers.

"The Texas Department of Family and Protective Services have demonstrated, in a most blatant way, their inability to properly care for, or even account for our children," the letter states.

"Many have been left in critical medical conditions, resulting in permanent mental damage through threats, intimidation and ultimately separating them from their parents, disregarding their own psychological expert advice to keep children with at least their mother."

Jessop accused Texas officials of "false allegations about the finding of abuse against teenage girls" and accused some Child Protective Services employees of "inhumane tactics and threats towards innocent mothers and children."

While not responding directly to the letter, DFPS spokesman Chris Van Deusen and others have repeatedly and strongly denied allegations made by several FLDS mothers that CPS workers threatened to never allow them to see their children again if they didn't cooperate or if the women returned to their homes at the YFZ Ranch.

"Those (allegations) are absolutely false. No one from CPS would say that," Van Deusen said.

Like Jessop, Martinez said accounting for all the children is a concern for her, too.
