Of course, there is the possibility that something may be discovered at a later date, but I'm sure they feel comfortable in the fact that they have meticulously combed through everything that's available to them.

Yeah, and Nancy, it's a relevant detail because it serves two purposes, really.

Number one, the uniqueness of that star could help determine where that article of clothing or that backpack came from.

That's an important detail.

And the second point is it can help in asking for public assistance.

This is somewhat unique.

And it can help some witness or somebody who's willing to cooperate, identify that clothing associated with a person.

So either way, I think it's relevant, whether it's a star, whether it's something else, just the fact that it's somewhat unique to that article of clothing.

Yeah, Nancy, there's a lot associated with this.

So it cuts both ways.

Going public and asking for public assistance and increasing this reward to now over $1,200,000 can bring substantial new evidence into the fold, into helping identify and helping discover new evidence.

But it also creates issues where you're getting

a lot of reporting much of which is not associated with this kind much of which may be people trying to capitalize on this tragedy to make money so this is going to be a monumental task as you said for the fbi and local law enforcement to comb through all of this reporting and all of this evidence

Key things you're going to be looking for, though, is anything unique that that that people that provide this evidence may know about the victim.

So whether that's proof of life information, whether it's unique information of the way she was dressed or articles that she may have had on her person, all of that is going to come into play so they can start to weed through this evidence and figure out what's relevant for the case and what is it.

But I recall back when 9-11 happened and we had tens of thousands, not millions of people reporting suspicious activity.

And the monumental task of going through and finding what's relevant to the crime and what isn't.

That's going to be a big challenge for authorities.

I reached out to my sources at the Attorney General's office in the state of Sonora, Mexico, which borders Arizona, and they confirmed with me that the FBI has in fact approached them and asked for their assistance.

They also stated that based on their initial investigations, they had no indications or no evidence that Nancy Guthrie entered Mexico or crossed the U.S.-Mexico border.
