Lol the coffee!:giggle:...I know where I live there are bunches of Caves. Some are large and well-known and some are small and known only to locals.
You're near the Smokies, lucky you

And I'm in Memphis on the mudplain...oh well.
Yes if people would just check property listings for Decatur County TN they would see how many of them list caves and springs.
The openings are often covered with vines and very hard to find.
That area also is pretty sandy instead of muddy.
There are many fire-roads and logging roads all thru that area.
I believe we are dealing w/an intelligent, perhaps college educated, perp here who has left all of that behind to live off the grid totally.
Possibly even a veteran of recent wars with military knowledge and training.
Let's think, if he was a local who just wanted to take Holly he would be missed.
Just like the TBI stressed today.
I think they were putting out what all profilers say to look for in these cases.
Anyone missing for unexplained reasons.
Anyone washing/cleaning a car "obsessively".
Anyone acting anxious.
Anyone reporting a vehicle/ATV missing.
Well with over 250 tips, there has been no such person.
Leads me to believe he is "local" but not known in the community.
What else can they say?
They basically are saying they have no idea who he is and that everyone is a suspect.
Back to square 1 and my belief that she is alive and he is waiting for the searchers to eventually have to give up.
Look at the Hailey Cummings case.
At so many others.
