With all the money and resources that have been used on this investigation, dropping a bitcoin to see what the one extortionist, has might be worth it.
My guess is that Nancy Guthrie didn’t leave that house alive and all the talk about kidnapping and ransom is just an afterthought.
Just MHO . . .
The longer this goes on, the less likely she will be found alive. She could have been taken across the border, whether alive or dead, an hour or so after the kidnapping when no one had any idea that she had been kidnapped.
