The issue of whose kids they are has come up on other threads.
If they are indeed hand picked as has been suggested, and they moved from Utah to Texas, that MAY mean they have crossed state lines with children who are not their own.
If they find kids whose DNA does not match any of the women, someone is going to be in deep doo-doo if the men either refuse to give samples or theirs doesn’t match either.
Its a felony to more children across state lines etc...
