She is mentally very, you know, she's perfect there.

But I'm going to assume, based on an 84-year-old woman living on her own with physical medical issues,

that there is help coming by to check on her.

One thing we do know, she has a pool person that takes care of the swimming pool.

We do know she has landscape yard people who do the gardening and keep it trimmed up.

We also know she has a housekeeper that comes by and cleans inside the house.

So all of those people are considered just outside the

inner circle, these employees, people who show up every week on a regular basis and know that house and know all the inner workings of the house.

Those are the people that are being vehicle swabbed this week, right now.

What we know, Nancy, is that as the investigation continues, these pictures just being released.

we know that the family, Savannah Guthrie, has seen the pictures and they're asking people to come forward.

Look at the pictures.

Look at the video.

You know if that's a loved one, if that's a friend, if that is somebody you know, you can tell by the way the person is walking before they put their head down.

They have a certain gait.

Take a look at it.

You can recognize the person actually knows when to slow down and stop a normal walk.

You see it right there.

And

I'm telling you, Nancy, if that's your husband, if that's your boyfriend, you know who that is.
