The only explanation that make sence to me are that the cops, or the family, or both know who the kidnapper is. Or, more likely, the kidnapper has contacted the cops or family and has kept his identity hidden. Either way, we aren't being told everything they know. That may be a good thing. But, if they really had no idea what was going on, it seems that they would be telling the public as much as possible so that they could help in the search.
I think that decentralizing the search has effectively killed the search and volunteer effort even though it is being reported as having been expanded by making it decentralized. They could have done the same thing by keeping the centralized command center that directs all of the neighborhood command centers. To me, that would be more effective. Let me know that I am wrong if you have seen an increase in the search effort. I haven't seen it. To me, that suggests that they know who has her or have been contacted by the kidnapper.
I don't buy the polygamy angle. I have met Tom Green a few times. I am freinds with some of his children. He is in jail right now so it wasn't him. There are tons of different Polygamy groups out there and some are plain nuts if you ask me. But, I have never heard of poligamist groups that kidnap their wives. That type of story has been made up by non-polygamists before. There is even an old black and white movie about it. I am a Mormon, not a polygamist. My polygamist friends were always taught that the Mormon church was led by the devil.
So when I heard the news last Friday that the search was going in a different direction, my heart sank, but actually, if the communities do get involved and urge their people to search their own property, it has broadened.
