Where did you get your info?
I saw the same link on kansas.com with someone saying it's also on AMW's site? Didn't go there to see for sure...
The Kansas/Lutheran church connection make it seem it may be possibly legit.
Some articles said that initially two couples were taken in (DR and his wife and her parents who live nearby...and at least they have been said to have been released...no one seems to know if his wife is still being questioned) and that evidence was taken out...
