Brad was a hostage negotiator with the FBI for 17 years right after they missed the court's deadline.

Now what can authorities do anything to get this mom to come back to Idaho?

I don't know about that, but clearly there are a number of things Tom they can do, for example, the force of all the mystery around the storage facility, Children's toys, other things.

Apparently, on one day Lori's brother went in and out of this facility like 78 times.

What is that all about?

They're going to need the timeline that why did she take J.

J out of school after he'd only been in school for three weeks?

And then it's the same month where no one ever sees them again.

So what I'm suggesting is there has to be a tightening off the timeline off both of them about Chad and Laurie because, let's face it, if they've harmed these Children in some form or fashion, people tend not to be sophisticated at that, and there's going to be clues.

There's going to be other people around them like Melanie Bordeaux, who apparently was running with them for a period of time.

What does she know?

In other words, draw the circle tighter of the people they were associated with, in particular when they were still in Idaho.

Right?

As we heard in claims report, those missing Children's mother and her partner had spouses who died under circumstances authorities now say are suspicious.

Authorities also tell ABC News they're working to build a case against the day bills.

Are those previous incidents relevant?

Well, there's certainly relevant as faras other crimes you know, in the mystery, in this case, obviously our two missing Children.

But the bigger mystery is, why did they disappear?

The why may help you figure out perhaps where they are at this given juncture, but I think again to go back.

The answer this to this story still lives in Idaho because again, public Sourced says, and the police say they don't think the kids ever made it to Hawaii, which means that this is really still focused in Idaho, in particular to finding both these Children.

You know, I want to go back to that clue you were talking about potential clue.

People put Children's items and other odds and ends and storage units all the time.

In the end, could that surveillance video be considered significant unless police find something meaningful inside?

Well, only if you know exactly what they took out and what the motive was in using the storage facility.

If these Children have been harmed, then why are you storing things in a storage facility knowing they're not there anymore?

We don't know the answer to that, of course, but the key is, why did they have that facility?

Because there's going to be a reason beyond just to store bicycles and things that belonged to the Children.

That's going to be, I think, potentially a key in this case.

All right, Brad, thank you so much for that.

We appreciate it.
