The Exact Moment Nancy Guthrie Was Taken — Her Own Pacemaker Recorded Everything

Added: 2026-05-26

[00:00:00]Her phone was found inside the house.

[00:00:03]Her medication was on the kitchen counter.

[00:00:05]Her car was still in the garage.

[00:00:08]Everything she owned was exactly where she left it.

[00:00:12]Every single thing.

[00:00:14]Except Nancy Guthrie herself.

[00:00:18]But here is what investigators knew from the very first morning they walked through that front door.

[00:00:24]Something else was still in that house, too.

[00:00:28]Something they could not hold in their hands or photograph or bag as evidence.

[00:00:33]Something that had been quietly recording all night long without anyone knowing.

[00:00:39]A signal.

[00:00:40]Small.

[00:00:42]Steady.

[00:00:43]Repeating every few minutes.

[00:00:45]Coming from inside Nancy Guthrie's own chest.

[00:00:50]And what that signal recorded in the 41 minutes between 1:47 and 2:28 in the morning of February 1st is what this video is entirely about.

[00:01:03]Because most people who followed this case heard the pacemaker story and thought they understood it.

[00:01:09]They did not. And the details they missed, the details that cardiologists, a former NSA hacker, and forensic technology experts have laid out piece by piece since Nancy disappeared, those details change everything about how you understand what happened in that house that night.

[00:01:31]This is Crime View.

[00:01:34]Before we get into the technology, I need you to understand who Nancy Guthrie is.

[00:01:40]Not just as a name in a headline. As a person. [music] Nancy is 84 years old. She is the mother of three children, Savannah, Annie, and Michael.

[00:01:52]Most Americans know her through Savannah, the co-host of NBC's Today show.

[00:01:58]But, the people who actually know Nancy know her as someone who has her own routines, her own faith, her own rhythms.

[00:02:07]She attends her church service online every single Sunday morning.

[00:02:12]She has done it faithfully week after week.

[00:02:15]That routine is important because the morning of February 1st, Nancy never logged in.

[00:02:23]The friend waiting on the other end of that connection noticed, made a call.

[00:02:28]>> And that phone call, that one small act of noticing something was off, is what started everything.

[00:02:36]Nancy had been home since 9:48 the previous night.

[00:02:40]Her son-in-law, Tommaso Cioni, had driven her back from a family dinner at Annie's house.

[00:02:46]He watched her go inside.

[00:02:48]The garage door closed at 9:50.

[00:02:52]Everything was normal. Nancy was home.

[00:02:55]She was safe.

[00:02:57]And between 9:50 at night and 1:47 in the morning, a period of roughly 4 hours, nothing unusual was recorded. No alerts, no alarms, no sign that anything was wrong.

[00:03:13]Then, at 1:47 in the morning, the doorbell camera disconnected.

[00:03:18]That disconnection is the moment this case begins.

[00:03:22]And I want to walk you through exactly what happened from that point. Not from 30,000 ft, but minute by minute, because the timeline itself tells a story that most coverage has gotten partially wrong.

[00:03:36]At 1:47 in the morning, the doorbell Nest camera at Nancy's front entrance went offline. Later, when the FBI worked directly with Google to recover cached data from that camera's cloud backup, they found something extraordinary.

[00:03:53]They found images, clear images of a masked figure, male, roughly 5 ft 9 to 5 ft 10, average build, approaching the front door carrying a 25-liter Ozark Trail Hiker backpack from Walmart, wearing a face mask, wearing gloves, and carrying a firearm.

[00:04:16]This person reached up and deliberately disabled that camera.

[00:04:21]Let that detail sit for a moment.

[00:04:24]He knew the camera was there.

[00:04:27]He came prepared to deal with it.

[00:04:31]This was not a spontaneous act.

[00:04:34]At 2:12 in the morning, 25 minutes after the camera went dark, the motion detection software that runs separately from the camera itself logged a person on site.

[00:04:47]The video was not available because Nancy did not have an active subscription that would have saved the footage.

[00:04:54]But the software registered presence, movement.

[00:04:58]Someone was there. 16 minutes later, at 2:28 in the morning, Nancy Guthrie's pacemaker disconnected from the app on her phone.

[00:05:09]Her phone stayed in the house. Nancy did not.

[00:05:14]That 41-minute window, from 1:47 to 2:28, is the period that investigators, cardiologists, and forensic technology experts have been picking apart ever since.

[00:05:28]And what they have found inside it is far more detailed than most people realize.

[00:05:34]Now, I need to stop here and correct something because one of the most widely misunderstood facts in this entire case involves what the 2:28 disconnect actually means.

[00:05:47]And if you have the wrong understanding of that, everything that follows will not land the way it should.

[00:05:54]When the news first broke that Nancy's pacemaker stopped syncing at 2:28, a lot of people assumed that meant her heart had stopped.

[00:06:04]That 2:28 was the moment something terrible happened to Nancy physically.

[00:06:10]That interpretation was wrong. And the doctors who explained why got far less attention than the initial panic did.

[00:06:18]Dr. Lawrence Epstein, the system director of electrophysiology at Northwell Health and a professor of cardiology at Hofstra Medical School, addressed this directly.

[00:06:30]He explained that a pacemaker syncs with an external device, a phone or a bedside monitoring unit, to share data.

[00:06:40]But when that external device is no longer in proximity to the pacemaker for long enough, the connection simply drops.

[00:06:48]He used an analogy that makes it immediately clear.

[00:06:52]He said, "Think about your AirPods.

[00:06:55]If you leave them on the couch and walk into another room, they disconnect from your phone.

[00:07:01]Your AirPods did not stop working.

[00:07:04]You just moved too far away.

[00:07:07]The same principle applies to Nancy's pacemaker.

[00:07:11]At 2:28, the Bluetooth connection between her pacemaker and her phone broke.

[00:07:18]Not because her heart stopped.

[00:07:20]Not because she was in crisis. Because Nancy herself moved out of range of the phone that was left behind in her house.

[00:07:28]She was being taken away.

[00:07:30]And the pacemaker, still functioning perfectly inside her chest, kept going.

[00:07:36]Kept recording. Kept sending out its quiet little signal into the dark.

[00:07:42]Dr. Rishi Anand, a cardiologist at Holy Cross Health in Fort Lauderdale, Florida, confirmed the technical mechanism.

[00:07:51]He explained that Nancy's pacemaker uses what is called Bluetooth low energy technology, a power-efficient communication standard specifically designed to make device batteries last for years.

[00:08:05]The pacemaker uses this low energy signal to communicate with its paired device.

[00:08:11]When that connection drops, the pacemaker does not know or care.

[00:08:16]It continues functioning exactly as it was designed to.

[00:08:20]This distinction between the pacemaker disconnecting and Nancy's heart stopping is not just a medical technicality. It is the foundation of everything investigators have been working with since the morning she was reported missing. Because it means the device inside Nancy's chest was still operating and still transmitting when the sync stopped. And that changes what investigators can potentially learn from it. Here is something that has received almost no attention in public coverage of this case. And once you understand it, you will understand why investigators moved so quickly to subpoena specific records in the first days of the investigation.

[00:09:03]Modern pacemakers do not just sync with a phone app. Many models, and the evidence strongly suggests Nancy's was one of them, also connect to a separate home monitoring base unit, a small device that sits plugged into a wall outlet, usually near the patient's bed.

[00:09:21]And that base unit does something the phone app does not. It transmits the pacemaker's stored data directly to the device manufacturer's cloud platform automatically, at regular intervals, sometimes near real time. The major manufacturers of implantable cardiac devices, companies like Medtronic, Abbott, and Boston Scientific, all operate these cloud monitoring platforms. And they store patient data continuously, time-stamped, logged, preserved.

[00:09:56]Dr. Srihari Naidu, a triple board-certified cardiologist and professor of medicine at New York Medical College, explained how this transmission system works in practice.

[00:10:08]He said that typically, once a day, the pacemaker sends a transmission that spools all information from the prior 24 hours to the doctor's office. In real time throughout the day, arrhythmias and significant cardiac events get flagged and transmitted as they occur. Which means this, even though the Bluetooth sync between Nancy's pacemaker and her phone stopped at 2:28, the manufacturer's cloud platform may already have received and stored cardiac data from earlier in the night. Data that does not disappear when the sync ends. Data that sits in a secure server, time-stamped, waiting.

[00:10:52]The FBI subpoenaed that cloud data within the first week of the investigation.

[00:10:58]The manufacturer complied. And the forensic analysis of what was in those logs is a significant thread in this investigation.

[00:11:08]One that investigators have been very careful about discussing publicly.

[00:11:13]There is a specific reason for that silence, and we will get to it.

[00:11:18]But first, let me explain something that Dr. Naidu said that most people following this case have never heard.

[00:11:26]Something that, when I came across it, made me stop and read it twice.

[00:11:31]He was asked a question during his interview with Parade magazine.

[00:11:36]A simple question.

[00:11:38]What happens to a pacemaker when its patient dies? Does it stop?

[00:11:44]His answer was not what most people would expect.

[00:11:48]He said, "In the hospital, when a patient with a pacemaker has a cardiac arrest and passes away, medical staff have to manually turn the pacemaker off. Because the pacemaker cannot tell the difference between a heart that is not beating because the person has died and a heart that simply needs a pacing pulse. So, it keeps sending electrical impulses. It keeps trying to make the heart beat. It keeps doing its job even after the patient is gone."

[00:12:19]He described what this looks like on a monitor.

[00:12:22]You see small electrical spikes, the pacemaker firing, but the heart tissue is not responding.

[00:12:30]The device does not know that. It just keeps signaling, keeps working.

[00:12:35]I am sharing that because I want you to understand exactly how determined and persistent this technology is.

[00:12:43]A pacemaker does not give up. It does not stop on its own. It keeps going as long as its battery holds charge.

[00:12:52]And the battery in Nancy Guthrie's pacemaker, depending on the model and how actively it has been pacing, has a service life measured in years, not days, not weeks.

[00:13:04]Years.

[00:13:06]Her pacemaker is still functioning right now. Still inside her chest. Still sending out its small regular Bluetooth signal.

[00:13:15]And that fact is directly connected to something investigators deployed. And something that may be the most technically extraordinary aspect of this entire investigation.

[00:13:27]His name is David Kennedy.

[00:13:29]He is a former hacker for the National Security Agency, the NSA.

[00:13:35]The same agency that monitors foreign communications and develops some of the most sophisticated surveillance technology in the world.

[00:13:44]After leaving government service, Kennedy built a career in cybersecurity.

[00:13:50]And when Nancy Guthrie disappeared, he built something else.

[00:13:55]He built what investigators and media eventually started calling a signal sniffer.

[00:14:02]Kennedy went on CNN on February 16th and explained exactly what this device is and how it works.

[00:14:10]He said, "Nancy has a pacemaker and in that technology there is what is called Bluetooth low energy, which emits a very non-powerful transmission that you can communicate with mobile devices with."

[00:14:25]Here is the key detail. Because Nancy's pacemaker disconnected from the app on her phone, Kennedy was able to confirm, based on that specific behavior, that her device uses Bluetooth low energy technology. Not all pacemakers do, but the way her device behaved at 2:28 told him exactly what technology he was dealing with and he built his signal sniffer to target that specific type of transmission.

[00:14:53]He told CBS News, "I was able to confirm that based on the pacemaker she has, it will broadcast every 3 to 4 minutes or so with a very small transmission.

[00:15:04]Every 3 to 4 minutes.

[00:15:06]A little electronic heartbeat reaching out into the air around Nancy saying, 'Here I am. Here I am.

[00:15:14]Here I am.'

[00:15:16]The problem is the range. Bluetooth low energy, under normal conditions, has a working radius of about 10 to 15 ft.

[00:15:25]That is it. The width of a small living room, which means that to pick up Nancy's pacemaker signal, a detection device would need to be within roughly 10 to 15 ft of her body.

[00:15:38]In a missing person's case where the victim could be anywhere across hundreds of square miles of desert, mountain, and urban terrain, 10 to 15 ft is essentially nothing.

[00:15:50]You could drive within a block of where she is and never get a hit.

[00:15:54]You could be in the same building and miss it entirely, depending on what is between you and her.

[00:16:00]Kennedy understood this. And he did what NSA-trained people do when they hit a technical limitation.

[00:16:08]He found a way around it.

[00:16:11]He tested on a drone at his own home.

[00:16:14]Using non-commercial equipment and off-the-shelf modifications, the kind of components you could order without specialized credentials, he extended the signal sniffers detection range dramatically.

[00:16:28]With high-gain antennas and signal amplifiers, Kennedy told CBS News, "The radius can extend to anywhere between 800 and 1,000 ft." 1,000 ft, roughly the length of three football fields.

[00:16:44]From 10 ft to 1,000 ft, that is the difference between finding someone in a small room and scanning an entire neighborhood from the air.

[00:16:56]Kennedy's device was mounted on a helicopter.

[00:16:59]Law enforcement sources confirmed to CBS News that the helicopter flew at low altitude, slowly, over areas of interest around Tucson.

[00:17:10]Sweeping, looking, listening for one specific Bluetooth signature, the unique address that belongs only to Nancy Guthrie's pacemaker.

[00:17:22]Morgan Wright, the CEO and founder of the National Center for Open and Unsolved Cases, described the technology to a local Tucson news station.

[00:17:33]He said, "It's got software running in it, continuously scans, and if it doesn't recognize hers, it just eliminates it until it locks on to the right one."

[00:17:44]Every Bluetooth device in the world has what is called a MAC address, a unique identifier, like a fingerprint.

[00:17:53]The signal sniffer is programmed with Nancy's pacemaker's specific MAC address and ignores everything else.

[00:18:01]Every other Bluetooth signal in the sweep area, phones, headphones, smartwatches, cars, filtered out. Gone.

[00:18:10]Only Nancy's device can trigger a hit.

[00:18:14]David Kennedy said on CNN, "All we need is one little transmission, and it's honed in just to her pacemaker's address.

[00:18:23]So, we're only seeing Nancy's address.

[00:18:27]This 100% could work.

[00:18:30]100% could work."

[00:18:34]That helicopter flew over Tucson.

[00:18:37]That device was scanning, and the results of that sweep have never been made public.

[00:18:44]George Mason University Professor Hassan Habre, an expert on cybersecurity and digital forensics, put the challenge into perspective. He said, "It's a bit like looking for a small object in your backyard with a microscope. You have to be right on the right spot at the right time to be able to detect it."

[00:19:05]Right spot, right time.

[00:19:08]The search area is enormous. The signal window is only a few seconds every 3 to 4 minutes.

[00:19:15]And if Nancy is inside a building, underground, in a vehicle, or behind anything that shields the signal, the sweep could pass within blocks and register nothing.

[00:19:27]Which is exactly why the forensic cardiologists working with the FBI were so focused on a different question entirely.

[00:19:36]Not where Nancy is right now, but where she was going during those 41 minutes.

[00:19:43]Because if you can constrain the search area, if you can narrow down where the vehicle was heading and how far it traveled, then you can make the signal sniffers job dramatically more manageable. Let us go back to the 41 minutes. Because now that you understand the technology, the timeline means something completely different.

[00:20:05]At 1:47, the camera goes dark.

[00:20:09]The suspect is on the porch.

[00:20:11]Blood is found on the front steps, confirmed by the Pima County Sheriff's Department as matching Nancy's DNA.

[00:20:19]Forensic pathologist Dr. Michael Baden examined the blood spatter pattern.

[00:20:25]He noted that the drops, mixed with air, suggest the blood came from the nose or mouth, rather than a wound to the extremities.

[00:20:35]This detail matters.

[00:20:37]It tells us Nancy was upright, moving, fighting.

[00:20:42]Dr. Srihari Naidu was asked to assess what an abrupt physical confrontation like this would mean for an 84-year-old woman with a pacemaker.

[00:20:52]His assessment was stark.

[00:20:54]He said for a patient of her age, an abrupt physical shock to the system, being startled awake, confronted, physically threatened in the middle of the night, could carry serious cardiac consequences. He described her as being at very high risk.

[00:21:12]The pacemaker in that scenario would not be sitting idle. It would be responding.

[00:21:18]Logging the cardiac events caused by extreme physical and emotional stress.

[00:21:24]Arrhythmia flags. Rate changes.

[00:21:28]The physiological record of a woman who is frightened and fighting.

[00:21:33]The 25 minutes between 1:47 and 2:12, the period before motion was detected, is when everything happened inside that house.

[00:21:44]When whatever confrontation occurred, occurred.

[00:21:48]When blood was shed on that porch.

[00:21:51]When an 84-year-old woman faced something no person her age should ever have to face.

[00:21:58]And then, at 2:12, motion was detected again outside.

[00:22:04]Someone was moving on the property.

[00:22:07]16 minutes later, at 2:28, the pacemaker disconnects from the phone.

[00:22:14]Nancy was gone.

[00:22:16]But here is the detail that investigators have been working with in terms of geographic analysis.

[00:22:23]The sync stopped at 2:28. The vehicle, whatever vehicle was used, had been moving by then.

[00:22:31]Based on when the motion detection logged presence at 2:12 and when the sync broke at 2:28, investigators have a window of approximately 15 to 20 minutes of potential vehicle travel time from Nancy's home before the connection was fully lost.

[00:22:50]15 to 20 minutes of highway travel from the Catalina Foothills neighborhood north of Tucson in the middle of the night when roads are clear, could put a vehicle anywhere from 12 to 25 miles away from her home in any direction.

[00:23:08]That radius, that geographic zone defined by what the timeline tells us, is where the signal sniffer sweeps have been concentrated.

[00:23:19]Not randomly, based on data, based on the timestamps, based on the 41 minutes that Nancy's own pacemaker documented before going silent.

[00:23:33]Now, I want to talk about what happens if the signal sniffer works, because this is the part of the story that nobody has adequately explained publicly. And it changes how you think about why the people who took Nancy would be extremely careful about where they keep her.

[00:23:50]If the signal sniffer detects Nancy's pacemaker, even a single transmission, even one 3-second window of her unique Bluetooth address being picked up by the receiver on that helicopter or drone, investigators get a location.

[00:24:05]They can home in from that general hit down to within a few meters, according to Kennedy.

[00:24:11]From a neighborhood to a building to a specific room.

[00:24:15]One transmission is enough to start that narrowing process.

[00:24:20]But there is something else, something that operates on a completely different channel from the signal sniffer. And this one does not require investigators to fly over the right location at exactly the right moment.

[00:24:33]Every major cardiac device manufacturer has a cloud monitoring platform.

[00:24:38]And that platform is not just storing historical data. It is actively waiting for new data.

[00:24:45]If Nancy's pacemaker comes within range of any compatible home monitoring base unit at any location, anywhere, that transmission gets logged.

[00:24:56]The manufacturer knows.

[00:24:59]And under the terms of the FBI's legal process with the manufacturer, that notification goes to investigators.

[00:25:07]Think about what that means.

[00:25:09]If the people who took Nancy ever bring her near another patient's home monitoring unit, if they ever take her to a medical facility, if a cardiologist or any clinician with a device programmer gets close enough to her chest to do a routine check, that event triggers a notification.

[00:25:29]It pings the manufacturer's servers, and the FBI gets an alert.

[00:25:35]This is one reason why, if the people holding Nancy understand how this technology works, and the level of planning in this abduction suggests they might, they would be extremely careful about allowing her anywhere near medical care. Because the moment her pacemaker handshakes with any compatible device on the network, law enforcement knows exactly which facility, exactly when.

[00:26:01]The pacemaker is not just a timeline tool.

[00:26:05]It is an active tracking thread that is still open right now, waiting for the one moment that closes the loop.

[00:26:13]There is a legal precedent for exactly this kind of evidence, and it happened in Ohio.

[00:26:19]And what it tells us about what pacemaker data can do in a courtroom is worth understanding.

[00:26:25]In 2016, a 59-year-old man named Ross Compton claimed that his house in Middletown, Ohio caught fire while he was sleeping.

[00:26:36]He said he woke up, grabbed his belongings, and escaped through a bedroom window.

[00:26:41]Investigators were skeptical.

[00:26:44]They got a search warrant for the data stored in his cardiac pacing device.

[00:26:49]What they found destroyed his account completely. A cardiologist reviewed Compton's pacemaker data from that night. His heart rate, his pacer demand, his cardiac rhythms before, during, and after the fire.

[00:27:05]And the cardiologist's conclusion, which was entered into the court record, was this.

[00:27:11]It is highly improbable that Compton would have been able to collect, pack, and remove the number of items from the house, exit his bedroom window, and carry numerous large and heavy items to the front of his residence during the short period of time he indicated given his medical condition.

[00:27:31]His pacemaker said he was physically active, vigorously active, not asleep.

[00:27:38]His own heart gave him away.

[00:27:41]Ross Compton was indicted on felony charges of aggravated arson and insurance fraud for allegedly causing 400 thousand dollars in damage to his home.

[00:27:53]His pacemaker data was central to the case against him.

[00:27:57]That was a landmark moment because it established in American law that the data inside a cardiac implant is evidence, that it can be subpoenaed, that it can be admitted, that it can be explained to a jury by a qualified cardiologist, and that a jury can understand it and act on it.

[00:28:19]In Nancy Guthrie's case, the prosecutorial implications of the pacemaker data go further than destroying an alibi.

[00:28:27]The data, depending on what the cloud logs contain, could document the physiological timeline of the abduction itself.

[00:28:36]The cardiac record of what Nancy's body went through in those 41 minutes.

[00:28:42]Expert testimony from a forensic cardiologist who can translate that data into language a jury can follow.

[00:28:50]That is not circumstantial evidence.

[00:28:53]That is as close to a first-hand account as a jury can get from a victim who cannot testify.

[00:29:00]Defense attorneys will scrutinize it.

[00:29:03]They will look at the chain of custody.

[00:29:05]They will question the methodology of the cardiologists who interpreted it, but the data itself, timestamped, logged, stored by the device manufacturer before the investigation began, that is not something that can be claimed to have been planted or manufactured after the fact.

[00:29:24]It existed before anyone knew a crime had occurred.

[00:29:28]It will exist in every future proceeding.

[00:29:32]Nancy's heart kept a record, and that record is going nowhere.

[00:29:38]I want to address something directly, something that has been circling the edges of this case since a note arrived at TMZ claiming Nancy Guthrie was dead.

[00:29:49]The note arrived on April 6th.

[00:29:52]The same sender, in the same communication window, sent a second note claiming they had seen Nancy alive in Sonora, Mexico.

[00:30:01]Retired FBI agents who reviewed the notes described them as fraudulent.

[00:30:06]The Bitcoin wallet included in the ransom demand received zero transactions. The contradiction between the two notes, one claiming she was dead, one claiming she was alive, both from the same person within hours, was the most obvious indicator that whoever sent them was not working from real information.

[00:30:28]But here is what the pacemaker data adds to that analysis.

[00:30:33]The sync dropped at 2:28 in the morning, not because Nancy's heart stopped.

[00:30:40]The cardiologists were clear. Dr. Epstein was clear.

[00:30:44]The connection broke because Nancy moved out of range of her phone.

[00:30:49]The pacemaker continued functioning.

[00:30:52]Nancy was alive at 2:28.

[00:30:55]The person writing fraudulent notes to TMZ does not have access to the pacemaker cloud data.

[00:31:02]They do not know what is in those manufacturer logs. They are guessing.

[00:31:08]And their guess that Nancy is dead is inconsistent with the last confirmed data point this investigation has from inside her own body.

[00:31:19]That does not tell us what happened after 2:28.

[00:31:23]Over 100 days have passed since that last data point. No one can say with certainty what her condition is right now.

[00:31:31]But the claim that she was dead contradicts what the medical evidence shows at the moment the clock stopped on the data we have.

[00:31:40]Someone who actually knew what happened to Nancy Guthrie after 2:28, someone who was there, would not be guessing in two contradictory directions in the same morning.

[00:31:53]The fraudulent notes tell us what the real kidnappers are not doing.

[00:31:58]They are not communicating publicly.

[00:32:01]They are not making demands through TMZ.

[00:32:05]They are being quiet.

[00:32:07]And the people who are being quiet are the ones investigators are focused on.

[00:32:14]Jim Clemente, the retired FBI supervisory special agent and criminal profiler who analyzed the surveillance footage, raised something that connects directly to the pacemaker data in a way that has not been widely discussed.

[00:32:30]Clemente said the suspect on the porch was, in his assessment, not a professional.

[00:32:36]He bumbled. He made mistakes.

[00:32:39]He revealed his wrist. He did not cover his mouth.

[00:32:43]He was, in Clemente's words, a street level operator. Someone hired to do a job.

[00:32:50]But here is what Clemente also said about the overall operation.

[00:32:55]He said there were sophisticated elements. The timing, the camera knowledge, the preparation.

[00:33:02]The fact that the person came equipped.

[00:33:05]That sophistication, Clemente argued, points to someone with more operational intelligence than the man on the porch himself.

[00:33:14]Now, think about what that means in the context of the pacemaker.

[00:33:19]Whoever planned this operation thought through the camera.

[00:33:23]Thought through the timing.

[00:33:25]Thought through the backpack, the gloves, the mask.

[00:33:29]But did they think through the pacemaker?

[00:33:32]Did they know that Nancy's pacemaker would log a cardiac event at 1:47 that could be cross-referenced with the camera timestamp?

[00:33:42]Did they know that the manufacturer's cloud platform would preserve data that the FBI could subpoena within days? Did they know that a former NSA hacker could build a device specifically to hunt for the Bluetooth signal still being emitted from inside Nancy's chest every 3 to 4 minutes, wherever she is?

[00:34:03]The gloves were planned.

[00:34:05]The mask was planned. The camera disruption was planned.

[00:34:10]But the pacemaker.

[00:34:12]The small device that has been quietly pinging its location signal into the air since the moment she was taken.

[00:34:19]That may not have been part of the plan at all.

[00:34:22]And that oversight, that single gap in an otherwise carefully considered operation, may be the thread that unravels everything.

[00:34:33]109 days since Nancy Guthrie disappeared from her home in the Catalina foothills north of Tucson, Arizona.

[00:34:42]Her pacemaker is still inside her chest, still functioning, still broadcasting its Bluetooth signal every 3 to 4 minutes.

[00:34:51]Somewhere out there, right now, that signal is going out, reaching into whatever space surrounds Nancy, a room, a vehicle, a building, and waiting for a receiver close enough to catch it.

[00:35:06]David Kennedy said it plainly, 100% could work.

[00:35:11]Morgan Wright said the signal sniffer continuously scans and eliminates every signal that is not hers until it locks onto the right one.

[00:35:21]Dr. Naidu said the pacemaker does not give up. Even in the most extreme circumstances, it keeps sending its signals. It keeps doing its job.

[00:35:33]And investigators, after 109 days, are still doing theirs.

[00:35:39]Sheriff Chris Nanos has said publicly the case is not cold.

[00:35:44]400 people are working thousands of leads.

[00:35:48]The FBI is involved at its highest operational levels.

[00:35:52]And somewhere in the manufacturer's cloud platform, the data from those 41 minutes is preserved, timestamped, waiting for the moment it becomes the centerpiece of a federal prosecution.

[00:36:06]Nancy Guthrie's heart recorded everything that happened that night.

[00:36:11]The fear, the struggle, the blood on the porch, the 41 minutes of darkness between the camera going off and the sink stopping.

[00:36:22]Her own body kept the record when every other recording was taken away.

[00:36:28]The suspect who planned this thought he had covered everything. The camera, the gloves, the timing.

[00:36:35]He did not plan for the small electronic device inside an 84-year-old woman's chest that has been quietly saying, "Here I am. Here I am. Here I am." every 3 to 4 minutes for over 100 days.

[00:36:52]That signal is still going out right now.

[00:36:56]And the people listening for it have not stopped.

[00:37:00]If you have any information related to Nancy Guthrie's disappearance, any detail, no matter how small it seemed at the time, the FBI tip line is open.

[00:37:11]The number is 1-800-Call-FBI.

[00:37:16]That is 1-800-225-5324.
