It's not a time where a child in school would be out rambling during the week.

They would normally be inside.

So a lot going on here, but not a lot of information, just that she is missing and we've got to find her.

Again, four foot eight, 125 pounds.

You would recognize a 16 year old that size.

Well, you know what, Nancy?

Earlier this week, we knew that law enforcement investigators had been back at the house, and we knew they were looking for something.

Well, apparently, they were all over the house looking for biological material, and that's what they found.

Investigators found biological material that does not belong to Nancy Guthrie.

They found it inside the home, and again, you pointed it out.

weeks after the home had already been searched, after evidence had been collected, and after the home was briefly turned back to the family before the investigators shut it back down.

But still, two weeks after this crime began, law enforcement finding biological material inside the home that does not belong to Nancy Guthrie.

The Searching Mothers of Sonora.

That's who the Guthrie family has reached out to.

This group of women actually search for missing people in Sonora.

Now, the reason this is important, Nancy, is there is Nogales, Arizona, and Nogales, Sonora, Mexico, just across the border.

We're talking 60 miles south of Tucson.

You go through Nogales, Arizona to Nogales, Mexico.

And the Searching Mothers of Sonora have been contacted by the Guthrie family to try and help find Nancy Guthrie.

It is more than just possible, Nancy, that Nancy Guthrie could have been taken across the border right there at Nogales.
