Chris Nano

Why would I operate from any other position than my team is operating from the same position?

She's out there.

We're going to find her.

This evening will mark one week since Nancy Guthrie was last seen.

And the sheriff here in Pima County, Chris Nano, says he believes she's still alive.

Late in the afternoon yesterday, a large number of investigators returned to the 84-year-old mother and grandmother's home.

They could be seen searching the property again, spending a lot of time on the roof of the home.

For me, it is simply this.

Somebody asked, Sheriff, how do you know, can you prove that she's alive?

And I just simply turn it around.

Can you prove she's not?

Why would I operate from any other position?

When we look at what we see at the scene, I would be very neglectful if I didn't say we need to look into this.

We can't just let it sit.

And so we contact our homicide team, which is a little unusual.

To be in your own bedroom, in your own bed, safe and secure in your own home, and to be taken like that in the middle of the night, that is not Tucson.

The Pima County Sheriff Chris Nano says it's what investigators found inside Nancy Guthrie's home that leads them to believe she was abducted, that she was sleeping at the time she was kidnapped and likely harmed.

Sheriff Nano says Nancy Guthrie's medication, wallet, and phone were found inside the home here on the northeast part of Tucson.

Sheriff Nano says the house is a crime scene.
