This is Hidden Killers Live with Tony Brewski, Stacey Cole, and Todd Michaels.

Before there was a masked man on Nancy Guthrie's porch, there was preparation.

Investigators have asked residents within two miles of Nancy's home now for surveillance footage,

covering a specific 32-day window January 1st through February 2nd.

But they didn't stop there.

They flagged two narrow timeframes within that window.

January 11th from 9 p.m. to midnight and January 31st from 930 to 11 a.m. That's not a fishing

expedition. That's an investigation that has some digital evidence pointing to specific moments

and is looking for the visual confirmation. Robin Drake, retired FBI special agency for the

counterintelligence behavioral analysis Program is with us.

Robin, let's get into where this investigation is at now that we're getting into another week,

entering week three, asking neighbors for footage from that window, but specifically those specific

spots. That's three weeks before the actual abduction. When we're looking at that

and they're asking for that information from neighbors, very specific spots, what is that,

what's that telling you about what they're specifically looking for and why? Yeah, kind of like we cover

with humans all the time is you baseline what normal looks like. You look for deviations and you zero in on

the deviations and see what caused it. And so what most likely is going on is that they baseline what

the electronics and digital footprint look like in that area. And they saw spikes, you know,

people's cell phones that were out of the unusual or movements or activities that are out of the unusual.

Again, areas that I'm not completely familiar with electronically, but there's something that deviated out of the norm during those times.

So now they're trying to cross-reference with other sources of information data to kind of zero in on what caused this spike from the deviation.

Are they looking too narrow? Are they look? I mean, I mean, I get, okay, let's look at these specific times.
