The perp walks up to the front door.

We don't see a car dropping them off.

We don't see a car picking them up in the neighborhood right there.

But if they were staging, meaning if the perpetrators were in that is vacant, they could be in that house for days.

They could be watching the comings and goings at Nancy Guthrie's home.

And then

When they decide it's time to go, walk across the backyard area.

Now, this is at the time, we're talking 2 to 2.30 in the morning, when Nancy Guthrie's neighbor facing her backyard, facing Nancy Guthrie's backyard, the dog went crazy and the two video cameras facing the backyard of Nancy Guthrie went silent, could not connect to Wi-Fi.

The vacant home is near there.

So if it's used by the perpetrators as a place to make their plan to stage, well, there you go.

You've got a clear shot walking into Nancy Guthrie's home and we've got a dog going crazy.

Nancy, he is under a microscope and it doesn't seem to bother him in the least bit.

Just to give you an idea, he has gone to the gym four out of five days.

He's spending 90 plus minutes inside the gym.

And by the way, he's being followed by the media because, again, this is a guy that's got a recall out on him right now.

He lives in an $850,000 gated community.

His home is a mini mansion.

He's driving a fairly new Corvette convertible, and they follow him to the gym.

We know that the investigation has really gotten into these construction sites, Nancy, to identify all personnel, including daily contractors who have come in.

They're trying to identify not just people, but you mentioned the trash.
