Nancy Grace

Dave Mack, take a look at this video of the porch guy.

There you see him, and that is Jan 31 into the early morning hours of February.

No package.

Then, by the next day, there is a package.

Take a look at it, Dave Mack.

Well, as a matter of fact, Dave Mack, in Pima County, an earlier attempted home invasion occurred

was facilitated by a female pretending, these guys in conjunction, by a female pretending to deliver a package.

Let's switch to the woman acting like, there she goes.

See her?

That's exactly what you're talking about.

But I see a problem, Dave Mack.

Let's go back to the before and after.

I mean, he may have the package in hand when he's skulking around or have it somewhere to reach for and pretend he's a delivery person.

But here you see porch guy, it's not there when he's there, and then it's delivered.

Here's where I'm going.

To Chris McDonough joining us, director of Cold Case Foundation, former homicide detective, and star of the interview room on YouTube, we here at Crime Stories have now conducted our own investigation.

Even the older models of Amazon delivery trucks have cameras.

They're not 360, but they're really good.

The newer delivery trucks do have 360.

So what, if anything, was captured in the days leading up to Nancy Guthrie's kidnapping?
