It seems to me that they should have mostly cadaver dogs out on this search if they think she is there, and that is hard for me to say.
I agree.
Sadly I'm sure they may have cadaver dogs with this many days passing. Also I'm sure they have alive ground scent dogs hoping upon hope they miraculously find her alive in the areas they are continuing to faithfully search.
Something is telling LE they believe she's STILL in this same general area. They make all of their decisions wisely.
They know already when an offender abducts a child the child's bodies are often found in the same general area.
Yes, it pains me greatly to even write this too, but, most assuredly LE knows all too well those often turnout to be the facts which they can't simply ignore them even though those facts are brutal.
But immediately upon arriving with the dogs they should have had air trailing scent dogs above all others because of their capabilities to trail live scents of victims who are inside a moving vehicle at the time of capture.
If LE has been able to also localize the scent of the offender the air trailing scent dogs are also capable of tracking the air scent left by them in a moving vehicles.
They are truly amazing animals who are warriors for justice many times for victims.
I find them right up there with the amazing dogs who can be in a boat, and can detect drowned or murdered victims way below the surface of their watery graves temporarily, who are found so they can be brought home for a respectful deserved burial.
