Texas ? The polygamist sect raided by authorities two months ago has its children back. But with a criminal investigation under way into allegations of sexual abuse, the splinter group’s troubles are not over.

Child-welfare officials have alleged that members of the sect pushed underage girls into marriages with older men, and while the last of 440 children seized from the ranch were returned to their parents Wednesday, prosecutors could still bring criminal charges.

“There have been criminal problems located out there,” said Schleicher County Sheriff David Doran, who was with state troopers and child welfare authorities when they raided Yearning For Zion Ranch in San Angelo, Texas, on April 3.
