How tech is being used in Nancy Guthrie disappearance investigation
NEWYou can now listen to Fox News articles!
Nancy Guthrie, the 84-year-old mother of “Today” show co-anchor Savannah Guthrie, was reported missing from her home in the Catalina Foothills area near Tucson after she failed to appear for church and could not be reached by family. When deputies arrived, several things stood out. Her phone, wallet and car keys were inside the home. The daily medication she relies on was left behind. Given her age and mobility challenges, investigators said she would not have left voluntarily.
The Pima County Sheriff’s Department has since stated publicly that the case is being treated as a suspected abduction, and the home was processed as a crime scene. As the search continues, investigators are piecing together not only physical evidence and witness tips, but also the digital trail left behind by everyday technology.

Why technology matters in missing person investigations
In cases like this, technology rarely delivers a single smoking gun. Instead, it helps investigators answer quieter but critical questions that shape a timeline. Investigators ask when everything still looked normal. They look for the moment when devices stopped communicating. They try to pinpoint when something changed. Phones, medical devices, cellular networks and cameras generate timestamps. Those records help narrow the window when events may have taken a dangerous turn.

How investigators connect data across agencies
Behind the scenes, investigators rely on advanced analytical systems to connect information from multiple sources and jurisdictions. In Tucson and across Pima County, law enforcement agencies use artificial intelligence-assisted crime analysis platforms such as COPLINK, which allows data sharing with at least 19 other police departments across Arizona. These systems help investigators cross-reference tips, reports, vehicle data and digital evidence more quickly than manual searches.
The Pima County Sheriff’s Department, Tucson Police Department and the FBI also work through real-time analytical crime centers, including Tucson’s Real-Time Analytical Crime Center (TRACC). These centers allow analysts to review large volumes of data together, from phone records and license plate reads to surveillance timestamps.
This type of analysis does not replace traditional police work. It helps narrow timelines, rule out possibilities and prioritize leads as new information comes in.
Bluetooth data and Apple’s potential role
iOS may retain low-level Bluetooth artifacts outside the pacemaker app. Access to this data typically requires:
- Legal process
- Apple cooperation
- Device forensic extraction
Bluetooth artifacts cannot determine distance. They cannot show that two devices were a few feet apart. What they can sometimes provide is timestamp correlation, confirming that a Bluetooth interaction occurred. That correlation can help align pacemaker activity with phone movement or inactivity. It is not publicly known whether Apple has been formally contacted in this case. An inquiry has been made. Apple typically does not comment on specific investigations but may confirm what categories of data could be available.
What the iPhone itself may reveal
Even without medical data, the iPhone left behind may provide valuable corroboration. With proper legal access, investigators may examine:
- Motion sensor activity
- Cellular network connections
- Wi-Fi associations
- Camera metadata
- Power and usage patterns
This data can help establish whether the phone moved unexpectedly or stopped being used at a specific time. Again, the value lies in confirming timelines, not speculating motives.
Cell tower data and coverage around the home
Public mapping databases show dense cellular coverage in the area surrounding the Guthrie residence. There are 41 cell towers within a three-mile radius. The closest carrier towers are approximately:
- AT&T at 1.0 mile
- Verizon at 1.4 miles
- T-Mobile at 3.0 miles
Carrier records can be analyzed to identify device connections, sector handoffs and anomalous activity during the critical window between Saturday evening and Sunday morning. This analysis is complex, but it can help confirm whether a device moved or disconnected unexpectedly.
Cameras, license plate readers and neighborhood footage
Investigators are also reviewing surveillance systems. Tucson primarily uses Verkada cameras integrated with the Fusus platform. Flock Safety cameras are used in other parts of the region, including South Tucson.
More than 200 automatic license plate readers are deployed in the broader area, allowing investigators to review historical vehicle movements during the critical time window. These systems can capture license plates, vehicle make and color, vehicle type and alerts tied to suspect vehicles.
Private sources may matter just as much. Neighbor doorbell cameras and home systems can provide important timeline markers, even if the footage is grainy. Some modern vehicles also record motion near parked cars if settings are enabled.

Ways to keep your loved ones safe
Technology can help protect older or vulnerable relatives, but it works best when combined with everyday habits that reduce risk.
1) Use connected cameras
Install smart doorbell cameras and outdoor security cameras that notify family members when someone unfamiliar appears. Alerts can matter just as much as recorded footage. Many newer systems allow AI-based person detection, which can alert you when an unknown person is seen at certain times of day or night. These alerts can be customized, so family members know when activity breaks a normal pattern, not just when motion is detected.
2) Wear an emergency pendant or medical alert device
Emergency pendants and wearable SOS devices let someone call for help with a single press. Many newer models work outside the home and can alert caregivers if a fall is detected. Some devices also include GPS, which helps when someone becomes disoriented or leaves home unexpectedly. This remains one of the most overlooked safety tools for older adults.
3) Enable device sharing and safety features
If your loved one agrees, enable location sharing, emergency contacts and built-in safety features on their phone or wearable.
On smartphones, this can include:
- Emergency SOS
- Medical ID access from the lock screen
- Trusted location sharing through apps like Find My
These features work quietly in the background, allowing help to reach the right people quickly without requiring daily interaction.
4) Create simple check-in routines
Use apps, text reminders or calendar alerts that prompt regular check-ins. If a message goes unanswered, it creates a reason to follow up quickly instead of assuming everything is fine. Consistency matters more than complexity.
5) Use devices with passive safety monitoring
Some phones, wearables and home systems can detect changes in normal daily activity without requiring a button press. For example, smartphones and smartwatches can notice when movement patterns suddenly stop or change. If a device that usually moves every morning stays still for hours, that shift can trigger alerts or prompt a check-in from a caregiver. Smart home systems can also flag unusual inactivity. Motion sensors that normally register movement throughout the day may show a long gap, which can signal that something is wrong. Passive monitoring works in the background. It reduces the need for constant interaction while still creating early warning signs when routines break.
6) Know emergency contacts and escalation steps
Enable smart alerts from home security systems so that family members know when doors open late at night, remain open longer than normal or when systems are armed or disarmed. Fire and smoke listener alerts and bedside panic buttons add another layer of protection, especially overnight. Car apps can also share safety signals, such as when a vehicle is unlocked, a door or window is left open or when location sharing is enabled with trusted family members.
“No single device can protect someone on its own,” a law enforcement expert told CyberGuy. “What helps most is layering. A camera paired with a wearable. A phone paired with check-ins. Technology paired with human attention. Each layer adds context and reduces blind spots. Together, they create earlier warnings and faster responses when something goes wrong.”
Kurt’s key takeaways
The disappearance of Nancy Guthrie is heartbreaking. It also highlights how deeply modern technology is woven into everyday life. Digital data from phones, cellular networks, and cameras can offer valuable insights, but only when used responsibly and in compliance with privacy laws. As this investigation continues, technology may help law enforcement narrow timelines and test theories, even if it cannot answer every question. In cases like this, every detail matters.

ChatGPT’s cheapest options now show you ads
ChatGPT users may soon start seeing ads in their chats, as OpenAI announced on Monday that it’s officially beginning to test ads on its AI platform. They’ll appear as labeled “sponsored” links at the bottom of ChatGPT answers, but OpenAI says the ads “do not influence the answers ChatGPT gives you.”
Currently, ads will only show up for users on the free version of ChatGPT or the lowest-cost $8 per month Go plan. Users in the Plus, Pro, Business, Enterprise, and Education plans won’t see any ads, so anyone who wants to avoid them has to pay at least $20 per month for the Plus subscription. There is one loophole — OpenAI notes that users can “opt out of ads in the Free tier in exchange for fewer daily free messages.”
Users on the Go tier can’t opt out of seeing ads, but users on both the Free and Go plans can dismiss ads, share feedback on ads, turn off ad personalization, turn off the option for ads to be based on past chats, and delete their ad data. According to OpenAI, advertisers will only get data on “aggregated ad views and clicks,” not personalized data or content from users’ ChatGPT conversations.
Additionally, not all users and chats will be eligible for ads, including users under 18 and conversations on certain sensitive topics “like health, mental health or politics.” Even adult users on the chatbot’s Free and Go plans might not immediately start seeing ads, since the feature is still in testing.

AI deepfake romance scam steals woman’s home and life savings
NEWYou can now listen to Fox News articles!
A woman named Abigail believed she was in a romantic relationship with a famous actor. The messages felt real. The voice sounded right. The video looked authentic. And the love felt personal.
By the time her family realized what was happening, more than $81,000 was gone — and so was the paid-off home she planned to retire in.
We spoke with Vivian Ruvalcaba on my “Beyond Connected” podcast about what happened to her mother and how quickly the scam unfolded. What began as online messages quietly escalated into financial ruin and the loss of a family home. Vivian is Abigail’s daughter. She is now her mother’s advocate, investigator, chief advocate and protector.

FROM FRIENDLY TEXT TO FINANCIAL TRAP: THE NEW SCAM TREND

How the scam quietly started
The scam did not begin with a phone call or a threat. It began with a message. “Facebook is where it started,” Vivian explained. “She was directly messaged by an individual.” That individual claimed to be Steve Burton, a longtime star of “General Hospital.” Abigail watched the show regularly. She knew his face. She knew his voice.
After a short time, the conversation moved off Facebook. “He then led her to create an account with WhatsApp,” Vivian said. “When I discovered that, and I looked at the messaging, you can see all the manipulation.”
That shift mattered. This is a major red flag I often warn people about. When a scammer moves a conversation from a public platform like Facebook to an encrypted app like WhatsApp, it is usually deliberate and designed to avoid detection.
Grooming through secrecy and isolation
At first, Abigail told no one. “She was very, very secretive,” Vivian said. “She didn’t share any of this with anyone. Not my father. Not me.”
That secrecy was not accidental. “She was being groomed not to share this information,” Vivian explained.
This is a tactic I see over and over again in scams like this. Once a scammer feels they have someone emotionally invested, the next step is to isolate them. They push victims to keep secrets and avoid talking to family, friends or police. When Vivian finally started asking questions, her mother reacted in a way she never had before. “She said, ‘It’s none of your business,’” Vivian said. “That was shocking.”
The deepfake video that changed everything
When Vivian threatened to go to the police, her mother finally revealed what had been happening. “That’s when she showed me the AI video,” Vivian said. In the clip, a man who looked and sounded like Steve Burton spoke directly to Abigail and referred to her as “Abigail, my queen.” The message felt personal. It used her name and promised love and reassurance.
“It wasn’t grainy,” Vivian said. “To the naked eye, you couldn’t tell.” Still, Vivian sensed something was off. “I looked at it, and I knew right away,” she said. “Mom, this is not real. This is AI.”
Her mother disagreed and argued back. She pointed to the face and the voice. She also believed the phone calls proved it. That is what makes deepfakes so dangerous. When a video looks and sounds real, it can override common sense and even years of trust within a family.
From gift cards to life savings
The money flowed slowly at first. A $500 gift card request raised the first alarm. Then, money orders and Zelle payments. What Vivian discovered next still haunts her. “She pulled out a sandwich baggie,” Vivian said. “About 110 gift cards ranging from $25 up to $500.” Those cards were purchased with credit cards. Cash was mailed. Bitcoin was sent. In total, the Los Angeles Police Department (LAPD) tallied the losses at $81,000. And the scam was not finished.

When the scammer took her home
After draining Abigail’s available cash, the scam did not stop. It escalated again. The scammer began pushing her to sell the one asset she still had: her home. “He was pressing her to sell,” Vivian told me. “Because he wanted more money.” The pressure came wrapped in romance. The scammer told Abigail they would buy a beach house together and start a new life. In her mind, this was not a scam. It was a plan for the future. That belief set off a chain reaction.
How the home sale happened so quickly
Abigail sold her condo for $350,000, even though similar homes in the area were worth closer to $550,000 at the time. The sale happened quickly. There was no family involvement. Her husband was still living in the home, yet he did not sign the documents. “She just gave away about $200,000 in equity,” Vivian said. “They stole it.”
What makes this even more troubling is who bought the property. According to Vivian, the buyer was a wholesale real estate company that moved fast and asked very few questions. Messages later reviewed by the family show Abigail actively trying to hide the sale from her husband. In one text exchange, she warned the buyer not to park in the driveway because her husband had access to a Ring camera. That alone should have raised concerns. Instead, the buyers went along with it. “They appeased whatever she asked for,” Vivian said. “They were getting a property she was basically giving away.”
These buyers were not the original scammers, but they benefited from the pressure the scammer created. The scammer pushed Abigail to sell. The buyers took advantage of the situation and the deeply discounted price. The home was not extra money, it was Abigail’s retirement. It was the only real security she and her husband had after decades of work. By the time Vivian uncovered the sale, Abigail was days away from sending another $70,000 from the proceeds to the scammer. Had that transfer gone through, nearly everything would have been gone.
This is the part of the story people struggle to process. Modern AI-driven scams are no longer limited to draining bank accounts or gift cards. They now push victims into selling real property, often with opportunistic players waiting on the other side of the deal.
Why police and lawyers could not stop the damage
Vivian contacted the police the same day she realized her mother was being scammed. “They assigned an investigator,” she told me. “He was already very aware of the situation and how little they can help.” That reality is difficult for families to hear, but it is common.
Many large-scale scams operate overseas. The money moves quickly through gift cards, wire transfers and crypto. By the time victims realize what is happening, the trail is often cold. “Most of these scammers are out of the country,” Vivian said. “No one is being held accountable.”
When the case shifted from criminal to civil
Law enforcement documented the losses and opened a case, but there was little they could do to recover the money or stop what had already happened. The deeper damage came from the home sale, which fell into a legal gray area far beyond a typical fraud report. Once the condo was sold, the situation shifted from a criminal scam to a complex civil fight.
Vivian immediately began searching for legal help. The first attorneys she contacted discouraged her. One told her it could cost more than $150,000 to pursue a case. Another failed to act even after being told about Abigail’s mental illness and history of bipolar disorder. At one point, an eviction attorney testified in court that Vivian never mentioned the romance scam, something she strongly disputes.
By March, Abigail and her husband were forced out of their home. By October, they were fully evicted and locked out. Both parents are now displaced. Abigail is living with family out of state. Her husband, now in his mid-70s, is still working because the home was his retirement.
It was only after reaching out through personal connections that Vivian found an attorney willing to fight. That attorney is now pursuing the case on a contingency basis, meaning the family does not pay unless there is a recovery. The legal argument centers on Abigail’s mental capacity and whether she could legally understand and execute a home sale under the circumstances. The buyers dispute that claim. The outcome will be decided in court.
This is why stories like this rarely end with a police arrest or quick resolution. Once a scam crosses into real estate and civil law, families are often left to navigate an expensive and exhausting legal system on their own. And by then, the damage has already been done.
Why shame keeps scams hidden
Many victims never report scams. Only about 22% contact the FBI. Fewer than 30% reach out to their local police department. Vivian understands why that happens. “She’s ashamed,” Vivian said. “I know she is.” That shame protects scammers. Silence gives them room to move on and target the next victim.
INSIDE A SCAMMER’S DAY AND HOW THEY TARGET YOU
What started as online messages escalated into gift cards, lost savings and the sale of a family home. (Kurt “CyberGuy” Knutsson)
Red flags families cannot ignore
This case reveals warning signs every family needs to recognize early.
Red flags to watch for
- Sudden secrecy about finances or online activity
- Requests for gift cards, cash or crypto
- Pressure to move conversations to encrypted apps
- AI videos or voice messages used as proof of identity
- Emotional manipulation tied to urgency or romance
- Requests to sell property or move large assets
I want to be very clear about this. It does not matter how smart you are or how careful you think you are. You can become a victim and not realize it until it is too late.
Tips to stay safe and protect your family
These lessons come from both Vivian’s experience and the patterns I see repeatedly in modern scams. Some are emotional. Others are technical. Together, they can help families spot trouble sooner and limit the damage when something feels off.
1) Watch for platform changes
Moving a conversation from Facebook to WhatsApp or another encrypted app is not harmless. Scammers do this to avoid moderation and make messages harder to trace or flag.
2) Question AI proof
Deepfake videos and cloned voices can look and sound convincing. Never treat a video or voice message as proof of identity, especially when money or property is involved.
3) Slow down major financial decisions
Scammers create urgency on purpose. Any request involving large sums, property sales or retirement assets should pause until a trusted third party reviews it.
4) Never send gift cards, cash or crypto
Legitimate people do not ask for payment through gift cards or cryptocurrency. These methods are a common scam tactic because they are hard to trace and nearly impossible to recover.
5) Talk openly as a family
Silence helps scammers. Regular conversations about finances, online contacts and unusual requests make it easier to spot problems early and step in without shame.
6) Reduce online exposure with a data removal service
Scammers research their targets using public databases. They pull names, phone numbers, relatives and property records. Removing that data reduces how easily criminals can build a profile.
While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.
Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting Cyberguy.com.

7) Use strong antivirus protection
Malware links can expose financial accounts without obvious signs. Good antivirus software can block malicious links before they lead to deeper access or data theft.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.
Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android and iOS devices at Cyberguy.com.
8) Protect assets early
Living trusts and proper estate planning add protection before a crisis hits. They can help prevent rushed property sales and limit who can legally move assets without oversight.
9) Use conservatorship when capacity is limited
“Conservatorship is the only way,” Vivian said. “Power of attorney may not be enough.” When a loved one has diminished capacity, a conservatorship adds court oversight and can stop unauthorized financial decisions before serious damage occurs.
Kurt’s key takeaways
This scam did not rely on sloppy emails or obvious mistakes. It used emotion, familiarity and AI that looked real. Once trust was built, the damage followed quickly. Money disappeared. Secrecy grew. Pressure increased. The home was sold. What makes this case especially painful is the speed. A few messages led to gift cards. Gift cards turned into life savings. Life savings became the loss of a home built over decades. Most families never expect this to happen. Many do not talk about it until it has already happened. The lesson is clear. Awareness matters more than intelligence. Open conversations matter more than embarrassment. Acting early matters more than trying to undo the damage later. If you want to hear Vivian tell this story in her own words and understand how fast these scams unfold, listen to our full conversation on the “Beyond Connected” podcast.

MrBeast just bought a banking app
Beast Industries, owned by YouTuber Jimmy “MrBeast” Donaldson, announced on Monday that it has acquired Step, a banking app designed for teens and young adults. The move comes a couple of months after Donaldson announced plans to start a new YouTube channel centered on personal finance and investing. His main channel has 466 million subscribers and has long been one of the most popular on YouTube, frequently featuring videos where Donaldson gives away huge sums of money.
MrBeast’s other business ventures also include a chain of ghost restaurants, the Feastables snack brand, and an upcoming phone service company called Beast Mobile. This is his company’s first dip into financial services.
Step is one of many mobile-only banking services, similar to Monzo or Revolut, but specifically aimed at teens, which may explain why Donaldson chose it over its rivals — his audience is mainly Gen-Z and Gen Alpha. Step’s investors also include Gen-Z influencers Josh Richards and Charli D’Amelio, the latter of whom has appeared on MrBeast’s YouTube channel.
