And on the ground right now, you have Pima County search and rescue vehicles.

You have FBI going door to door in the brush area, all in Annie Guthrie's neighborhood, which is about 15 minutes away from Nancy Guthrie's house.

And I brought in former FBI Special Agent Michael Easter to ask him,

After these videos have been released and this footage of this person at Nancy's house, what they could be looking for in any Guthrie's neighborhood.

So to me, this person in this video footage, even though didn't seem too prepared to dismount a camera, there just seemed to be no sense of urgency.

He's just kind of walking towards it, walking backward, turning around.

Let me go get this bush.

Seemed very comfortable in that moment, not really worried anyone would see him or he would get caught.

So that brings back to...

Who would feel comfortable doing this to 84-year-old Nancy Guthrie?

Who would have the whereabouts on how to get the windy roads go up to her house?

And something that I asked Sheriff Mark Lamb about was,

was the timeline.

Because there's so many questions that we know to be true is that timeline where that camera was dismounted 1.47 a.m.

and Nancy's pacemaker wasn't disconnected to 2.28.

To me, that seems they weren't in a hurry inside the house either.

No sense of urgency.

And so I asked Sheriff Lamb his thoughts on that.

So meanwhile, back at Nancy Guthrie's house on Tuesday, February 10th, day 10 of the search, you have a pizza boy that went up to this door to deliver a pizza.

It's still not secure.
