Chapter 1: What is the main topic discussed in this episode?
This is an iHeart Podcast. Guaranteed human. Crime Stories with Nancy Grace. Savannah Guthrie's mother, Nancy Guthrie, missing day 34. It defies all logic. This, as we learn, in the last hours, the FBI has been going door to door asking certain neighbors, did they have an Internet disruption? The night Nancy Guthrie was abducted was a signal jammer used or some other apparatus.
Also, we learn investigators are now talking to trash companies. Why? And this, as we learn, the DNA, the stranger DNA, not a family member, not someone that worked with Mrs. Guthrie, was definitively found in the home. What difference does it make?
Chapter 2: What recent developments are there in the search for Nancy Guthrie?
Good evening. I'm Nancy Grace. This is Crime Stories. I want to thank you for being with us. A lot happening in the search for Nancy Guthrie straight out to Crime Stories investigative reporter Dave Mack. Dave, what do you mean the FBI going not exactly door to door, but to certain neighbors, which I find interesting, not door to door, not every neighbor. Certain targeted neighbors, why them?
What do they know? What can they offer that the next door neighbor cannot offer? Is it a vantage point?
Chapter 3: Why is the FBI asking neighbors about internet disruptions?
Is it their work schedule? In other words, were they coming home in the middle of the night? Were they getting up early? What did they notice? Were they out and about? Was their cell phone identified moving around in the area in the early morning hours? My point is, it could be a myriad of possibilities. Not everything neighbor was questioned. Certain people were isolated in question.
I'll get to that in a moment, but Dave Mack, interference with their internet signal, what?
The FBI yesterday was specifically looking at the home just west of Nancy Guthrie's home, and they were specifically, the FBI, specifically asking about internet connectivity issues the night that Nancy Guthrie disappeared. Very specific about the time and very specific about what could have happened with their internet connectivity.
Now, Nancy, as we've pointed out before, while this is a neighborhood, the homes are not close together. They are separated by a bit. And in this particular case, they, as you mentioned, FBI did not go to every house. They only went to specific homes. In particular, the home to the west of Nancy Guthrie's house. That's the one they spent the most time with.
And again, checking on internet connectivity on February 1st.

Chapter 4: What role do trash companies play in the investigation?
That's what they're looking at.
You're seeing video, drone video, from our friends at Fox News. How irritating. Look, look. It's like gnats.
Chapter 5: What evidence was found in Nancy Guthrie's home?
Straight out to, I'm going to circle back on what you just said, but to Bob Krieger joining us, former SWAT commander. That's not easy to obtain. Former SWAT commander, Pima County Sheriff's Office, 30 years in Pima. Did you see the video we just showed? Do you see the media chasing down the FBI? I mean, they can't, they can't make a move without being watched.
People are trying to figure out what they're saying. They're trying to read their lips. Did you ever encounter anything like this where your every move was watched while you tried to work, Bob?
Not specifically like that, but, you know, it started a handful of years ago where First Amendment auditors decided they wanted to videotape and look at everything that law enforcement does. It's a skill that you learn and you learn that as long as they're a decent distance away, you just kind of ignore them. Like you said, they're like gnats.
You know, one or two- Hey, Bob, can I tell you a story? Sure, go ahead. I remember the first time that Court TV covered one of my trials live. I was so oblivious, focusing on the answer, the jury, the question, the jury, the judge. I mean, it's like a tennis match. You zone out everything else.
And later, I found out that the camera caught me trying to put my hair up, which I wore on top of my head at the time, adjusting my dress and all that. you know, before the jury would come back in. So, you know, you have to be in a zone if you're focusing on what's happening. And can I see that video again from our friends at Fox?
It's drone video of the FBI, and that's how we know they were only going to certain places doors, certain neighbors. So can I see the other photo now, please? Control room of Nancy Guthrie's home and Dave Mack, if you could look at this because see, we don't know how this is situated. The overhead shot of Nancy Guthrie's home. Okay. When you're say saying West,
See, from what we're seeing, I don't know which home that would be. Let me see a far shot. That's from 12 News, by the way. A high aerial. Is it to the right of her home or the left of her home? In front or in back? What is west as it is oriented to this photo, Dave Mack? Do we know what would be west? I would assume it's to the left of her home.
Okay, that's what I assumed, but Nancy, I don't have a, there's not a compass here on the picture to know exactly where. That's why I used the identifier.
Okay, we're going to find out. Control room, that will give you something fun to do. Figure out what is east, west, north, and south in this photo. Just FYI, all you need to know, control room, is what's north. I'll do the rest for you. Back to the topic. The FBI going, not quite door-to-door, but certain neighbors isolated.

Chapter 6: How can signal jammers affect internet connectivity?
First of all, you've already told me something inconsistent. I believe you, but in my mind it's inconsistent. You said it's illegal, but you can get it on the Internet. Just like drugs, they're illegal, but you can get them anywhere. So a signal jammer is illegal in the US. I wonder where are they legal? But that's a whole nother can of worms. Oh, there's a picture. Signal jammer.
And then you said, okay, so I've reconciled that, James. Now you said you flood the internet. What does that mean? How do you flood the internet?
If you think of your wireless router, It's got really two signals, 2.4 gigahertz and your 5 gigahertz signal band. That's how it talks back and forth. It sends and receives data. Now, these jammers don't erase the signal. But what they do is they emit such a loud signal that it's going to overwhelm your device.
Just like I said, going to a movie theater and having someone beside you screaming in your ear the whole time, you can't hear the movie, but the movie is still going on. It's just going to interfere with the transmission of the data.
Stop right there. I need to, I need to, I've got to take this in tiny sips. Okay. Number one, it's illegal. Number two, you can get one on the internet. Three, internet, everybody's home internet through their routers gives a signal and receives a signal. A signal jammer does not stop either the receipt or the transmission of your home router.
What it does is it sends out its own signal that is so strong and overpowering. Okay, then you finish the rest of the sentence. That's as far as I got. Go ahead.
It's so strong and overpowering that nothing can be sent or received. It can't be heard. In this case, maybe the Nest camera is broadcasting video to the router. The router is then sending it to the service. Now, when a Wi-Fi jammer is set next to that camera, it's going to scream so loud that the signal from the device, from the camera, isn't heard by the router.
It's just going to jump between it and block that signal.
Hold on, hold on, hold on, hold on. Pretend you're talking to kindergartners. The Wi-Fi jammer, when set next to Nancy Guthrie's nest, what was the rest of that?

Chapter 7: How does the timeline of events relate to the investigation?
Wow. Overrides signal so loudly, the Nest can no longer hear the transmission it's supposed to be receiving.
And sending, yes.
Is that right?
Exactly.
Wow, okay, you just explained a lot to me. Now, I want you to look at something. Control room, could you please show the item sticking out of the door, the porch, guys? There you go. Keep going, keep going, keep going. Stop. So what we had thought, oh, you're still moving. Could you ISO that for me?
What we had thought was a walkie-talkie, could that be the signal jammer or a signal jammer, James Bass? It's possible.
It is very possible that that is a Wi-Fi signal jamming antenna. You normally would see more than one antenna. There's usually one antenna per band that it's going to try to interfere with, as your illustration here shows. So it could still be a walkie-talkie of some sort, but that antenna is also something that you would see on a Wi-Fi jammer.
So it could be a jammer. Do all jammers have the three antenna?
No. Some have two, some have three, depending on the jammer.

Chapter 8: What are the implications of a deep-cleaned vehicle in this case?
That's exactly what they're probably trying to establish. A small unit has a very small area that it can jam. It's got to be close to the device to actually stop the signal. So what they're looking is houses that are going to be close, trying to establish a timeline or possibly a route in or out of the neighborhood based off of a signal interruption.
Okay, that was really smart. Hold on, hold on. I was trying to discern something. If the neighbors say their Internet was not interrupted, that could mean there was not a blanket, like cable disruption, that would be more likely, not absolutely, but more likely that a signal jammer was used at Nancy's home. If nobody else had a problem...
Nancy was the only one that had a problem, more likely a signal jammer was used. Although Bob Krieger has another idea, former SWAT commander, 30 years in LA law enforcement in Pima, what's your idea?
Well, if they were asking about strictly Internet service going out, the jammers have a real small radius to work in. If the whole neighborhood went out, it'd be probably more likely that someone cut something in a box or at the house or houses to knock off the service. That's going to cut all the Internet activity, not just the individual Wi-Fi signals. So there's, you know, it just shows.
What does that mean, Bob Crager, to have the fiber optic cut?
That means you can't get on the Internet anymore. Your Internet is now broken. You can't talk to anything. You can't stream anything. No data is coming in. No data is going out. What the jammer does is it just affects the Wi-Fi signals from your router inside your house, all your devices that are pushing information out. So the Internet is still working. It's just being jammed.
If the cables are cut or there's a big disruption, that's when the whole neighborhood would go out. That's when you'd get Comcast or Xfinity or whoever your provider is saying, hey, guess what? The Internet's down in your neighborhood. You can't do anything. And today's world, people are going to panic and everything stops.
No streaming, no sales or no anything that you do on the Internet is done. And that's an absolute no.
Bob Krieger, if the fiber optic was the issue, when you say cut, do you mean physically, manually cut, severed, like with scissors or a knife? Yes. Okay. Wouldn't there be evidence of that following? I mean, they can't cut it and repair it. So wouldn't that still be cut the following morning?
