Not speaking from experience here, just some knowledge that I've picked up over the years. But it's my understanding that, in strict religious communities such as this one, everyone's activities and behavior are closely monitored by the leaders. It would be unlikely, though not impossible of course, that a young, girl would have the opportunity to have sexual relations with anyone without the leadership both knowing and approving. In fact, as I understand these things, they are most likely to be forced into a relationship with one of the leaders of the group, either through coercion or something akin to "brainwashing".

That's not to say that this was, indeed, the case here. I don't know, for sure, and I doubt anyone outside the community knows, either. And I don't believe that they should be subjected to attacks by the government without due process. But they should be required to submit to some oversight once the allegations of abuse have been made. And as I said in a previous comment, the DNA would tell the tale.
