Nancy Grace

What's the chance that right now, David Richards, as we go to air tonight, there is somebody in some office, either in Tucson, Phoenix, or Quantico,

some office with those horrible overhead lights on, trying to figure this out, trying to trace that email, trying to trace that Bitcoin account.

I'd say 100 to nothing.

Also tonight, I want you to take a look at a monitor that has appeared in a shot of Mrs. Guthrie with Savannah.

We believe in Mrs. Guthrie's home.

Look carefully at the laptop to Mrs. Guthrie's left, your right.

It looks like an outdoor surveillance, home surveillance.

Look at that.

Okay, let's take it in full again, please.

If you will now look just over Mrs. Guthrie's left shoulder on the right of your screen, that looks like it's being projected up on like a TV monitor.

What is that, Brian Fitzgibbons?

Okay, I don't get it, David Richards.

How can there be no trace of this, nothing left behind when I can see that she has home surveillance video and she's looking at it on her laptop?

Why can't that be resurrected?

You know, Google pulled a miracle or a miracle dropped on their heads from above and they were able to resurrect the video of the porch guy.

We're praying for another miracle to help crack the case.

This says theories run rampant that the porch guy was actually wearing a shoe covering.

Let's take a look at some of the possibilities.

Okay, that's one example of a shoe covering, a covering like this.

To Brian Fitzgibbon's USPA Nationwide Security, what difference would it make if he were wearing shoe coverings?
