Texas ? Texas officials who took 416 children from a polygamist retreat into state custody sent many of their mothers away Monday, as a judge and lawyers struggled with a legal and logistical morass in one of the biggest child-custody cases in U.S. history.

Of the 139 women who voluntarily left the compound with their children since an April 3 raid, only those with children 4 or younger were allowed to continue staying with them, said Marissa Gonzales, spokeswoman for the state Children’s Protective Services agency. She did not know how many women stayed.

“It is not the normal practice to allow parents to accompany the child when an abuse allegation is made,” Gonzales said.

The women were given a choice: Return to the Eldorado ranch of the Fundamentalist Church of Jesus Christ of Latter Day Saints, a renegade Mormon sect, or go to another safe location. Some women chose the latter, Gonzales said.

The state is accusing the sect of physically and sexually abusing the youngsters and wants to strip their parents of custody and place the children in foster care or put them up for adoption.
