I don’t know if Annie Guthrie and her husband did anything, I tend to believe this is a false trail.

What is obviously clear to me is that the kidnapper has detailed knowledge of the premises. This suggests past time spent in the area and in the home, pointing to a relative. Personally, I hope the Bureau gets on the schtick and avails themselves of remote viewers, Guy’s like Joe McMoneagle, who is now 80 years old but who has a track record making him the grand guru of remote viewing.
You mean like clairvoyants?
My brother is a furniture refinisher (the best you will ever meet, btw) and has worked in that area even though I am in Phoenix. He says it’s like the Tucson Beverly Hills. Really very nice area.
Those people have workers all the time installing things, fixing things, cleaning things. It is not hard to find someone among them that has been in that house, maybe more than once.
Could really be anybody. Does not have to be a relative. I could be wrong but that field is wide.
Ask a “remote viewer?” You would do better asking a lamppost, or perhaps a fire hydrant...
