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.
As digital footprints grow more detailed, should tech companies give law enforcement broader access when someone goes missing? Let us know by writing to us at Cyberguy.com.

Blue Origin explosion is a major setback for NASA’s Moon plans and Amazon’s Starlink competitor
While Blue Origin investigates the root cause behind last night’s spectacular explosion of its New Glenn rocket, it’s already clear that this will be a major setback for NASA’s Moon base plans and Amazon’s fledgling Leo space internet constellation.
The incident occurred at about 9pm at Blue Origin’s Florida launch site during a hot-fire test, where seven engines in the booster stage are lit while keeping the 322-foot-tall rocket fixed to the launchpad. The explosion and ensuing fireball severely damaged the only launchpad Blue Origin has for its New Glenn rocket.
“It’s too early to know the root cause but we’re already working to find it,” wrote Blue Origin boss Jeff Bezos on X. “Very rough day, but we’ll rebuild whatever needs rebuilding and get back to flying. It’s worth it.”
According to sources speaking to Ars Technica, the transporter-erector and one of the lightning towers at LC-36A may not be salvageable. “New Glenn almost certainly will not launch again in 2026, and frankly a launch during the first half of 2027 would be heroic given the launch site concerns,” writes Eric Berger, senior space editor at Ars Technica.
Such a delay would affect NASA’s Moon base plans. NASA announced on Tuesday that New Glenn would deliver a robotic lunar lander as soon as fall 2026. In 2027, Blue Origin is also scheduled to participate in the upcoming Artemis III mission, which will see astronauts docking their Orion capsule with lunar landers developed by SpaceX and Blue Origin.
“Spaceflight is unforgiving, and developing new heavy-lift launch capability is extraordinarily difficult,” said NASA administrator Jared Isaacman on X. “We will work with our partners to support a thorough investigation of this anomaly, assess near-term mission impacts, and get back to launching rockets.”
The New Glenn rocket that exploded Thursday night was being prepped to carry 48 Amazon Leo satellites — the largest batch ever slated for a single launch — into low-Earth orbit on an upcoming mission. The satellites were not onboard.
To date Amazon has launched just over 300 of the 1,618 Leo satellites the FCC requires by July 30, 2026. Amazon has applied for an extension to keep its license.
Amazon had been counting on New Glenn’s massive payload capacity and reusable boosters to accelerate a launch schedule that is already behind. Without its primary workhorse, Amazon will be forced to rely more heavily on secondary providers like United Launch Alliance (ULA) and Arianespace — and its chief rival, SpaceX.
“Sorry to see this,” wrote fellow billionaire spaceman Elon Musk on X. “I hope you recover quickly.”

Could the 7-Eleven breach affect you?
NEWYou can now listen to Fox News articles!
You may stop at 7-Eleven for coffee, gas, snacks or a quick drink. What you probably do not expect is to see the company’s name tied to a data breach involving personal information.
That is what happened after breach notification service Have I Been Pwned added 7-Eleven to its database. The service says the breach exposed about 185,000 unique email addresses. The exposed data also included names, dates of birth, phone numbers and physical addresses.
The company later said the breach involved certain 7-Eleven systems used to store franchisee documents. That detail is important because the exposed data appears tied to franchise-related records, rather than ordinary store purchases. Still, if your information was part of the leak, the risk can feel very personal.

CONDUENT DATA BREACH HITS MILLIONS ACROSS MULTIPLE STATES

7-Eleven data breach: What happened?
According to Have I Been Pwned, 7-Eleven was targeted in April 2026 by a “pay or leak” extortion campaign linked to ShinyHunters. The data was later published that same month.
Hackers claimed they had stolen data and threatened to release it unless they were paid.
7-Eleven’s chief information security officer, Jim Kastle, said an unauthorized third party accessed an internal server that contained franchisee documents. The company said the incident involved certain systems used to store those records.
That makes this breach different from a typical customer checkout breach. Based on the company’s notification language, the affected records appear connected to franchise applications or franchisee documents.
10 SIGNS YOUR PERSONAL DATA IS BEING SOLD ONLINE
What data was exposed in the 7-Eleven breach?
Have I Been Pwned says the breach exposed 185,000 unique email addresses. The exposed information also included:
- Names
- Dates of birth
- Physical addresses
- Phone numbers
- Email addresses
Some breach filings also pointed to more sensitive details in certain records. Those details included Social Security numbers and driver’s license numbers. That extra information raises the stakes. Names and addresses can fuel phishing. Dates of birth can help scammers sound convincing. Social Security numbers and driver’s license numbers can create a higher risk of identity theft.
THINK YOU’RE SAFE? IDENTITY THEFT COULD WIPE OUT YOUR ENTIRE LIFE’S SAVINGS
Why the 7-Eleven breach could still matter to you
You may wonder, “I only buy coffee there. Should I care?” For most everyday 7-Eleven shoppers, this breach may not involve store purchase history. However, anyone who applied to become a franchisee, handled franchise documents or shared personal information through that process should pay close attention.
Even when a breach affects a limited group, the exposed data can still spread. Once hackers publish personal records, scammers can reuse them in many ways.
Fake emails could mention 7-Eleven by name. Phone calls may include your name, number or address to sound legitimate. Scammers could also send messages that pressure you to “verify” your identity after the breach. That is where the real damage often begins.
MICROSOFT ‘IMPORTANT MAIL’ EMAIL IS A SCAM: HOW TO SPOT IT
How scammers may use leaked 7-Eleven data
Hackers do not need every detail about you to cause trouble. A few personal facts can make a scam feel believable.
For example, a scammer might send an email that claims to be from 7-Eleven, an identity theft protection company or a breach response team. The message may say you need to click a link to activate identity protection. It may also ask you to confirm your Social Security number, upload your driver’s license or enter banking details.
That kind of message can feel urgent. Scammers count on that reaction.
They know people act quickly when they feel scared. They may use phrases like “final notice,” “account locked,” or “breach claim pending” to push you into clicking before thinking.
DIY IDENTITY PROTECTION VS PAID SERVICES: WHAT WORKS IN 2026
What 7-Eleven says about the data breach
7-Eleven reportedly notified affected individuals and arranged identity theft protection for up to 24 months.
If you receive a notice, read it carefully. Use the official instructions in the letter. Avoid clicking links in random emails or text messages that claim to offer breach help.
Instead, type the official website address into your browser yourself. You can also contact 7-Eleven through a verified channel.
We reached out to 7-Eleven for comment, but did not hear back before our deadline.

Ways to stay safe after the 7-Eleven data breach
A breach can feel out of your hands. However, you still have several smart moves available.
1) Check whether your email was exposed
Go to Have I Been Pwned at haveibeenpwned.com and search your email address. The service lets you see whether your email appears in known breach databases, including the 7-Eleven listing. If your email appears, do not panic. Treat it as a signal to tighten your accounts and watch for targeted scams. When done, come back here for Step 2.
2) Change your passwords immediately
Start with your most important accounts, such as email, medical and banking. Use strong, unique passwords with letters, numbers and symbols. Avoid predictable choices like names or birthdays. Never reuse passwords. One stolen password can unlock multiple accounts. A password manager makes this simple. It stores complex passwords securely and helps you create new ones. Many managers also scan for breaches to see if your current passwords have been exposed. Check out the best expert-reviewed password managers of 2026 at Cyberguy.com.
3) Watch for fake breach emails
Be careful with emails, texts or calls that mention 7-Eleven. Scammers may use the breach as bait. Do not click links from unexpected messages. Instead, go directly to the company’s official website. Also, avoid opening attachments unless you fully trust the sender. The best way to protect yourself from malicious links 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 safer.

4) Turn on two-factor authentication
5) Place a fraud alert or credit freeze
If your Social Security number or driver’s license number was exposed, consider a credit freeze with Equifax, Experian and TransUnion. A credit freeze makes it harder for criminals to open new accounts in your name. You can lift it when you need to apply for credit. A fraud alert can also warn lenders to take extra steps before approving new credit.
6) Remove your personal information from data broker sites
Leaked information can become even more dangerous when scammers combine it with details already floating around online. Data brokers may list your home address, phone number, relatives, age and other personal details.
You can remove your information manually from individual data broker sites, though that process takes time. A data removal service can help automate opt-out requests and continue monitoring for your information when it reappears. 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) Consider identity theft protection
If your Social Security number or driver’s license number was exposed, identity theft protection may be worth considering. These services can monitor your credit, alert you to suspicious activity and help with recovery if someone tries to open accounts in your name. If you receive an official breach notice from 7-Eleven, review any identity protection offer carefully. Go through the official letter or verified company website rather than clicking links in random emails or texts. See my tips and best picks on Best Identity Theft Protection at Cyberguy.com.
8) Monitor your mail and financial accounts
Watch for unfamiliar bills, credit cards, loans or government notices. Also, review your bank and credit card statements. If you see something suspicious, report it right away. The sooner you act, the easier it can be to limit damage.

9) Be careful with phone calls
If someone calls and claims to help with the breach, slow down. Do not give out your Social Security number, driver’s license number or banking details over the phone. Hang up and call the company back using a verified number.

Kurt’s key takeaways
Data breaches have become so common that it is tempting to shrug them off. That can be risky. Personal details such as your name, address, date of birth and phone number can give scammers a running start. The 7-Eleven data breach may not affect every customer who has ever bought a Slurpee or filled up at one of its stores. However, for the people whose information was exposed, it can create a long tail of fraud risk. The best move now is simple. Verify before you click, strengthen your accounts and assume scammers may try to use this breach as a conversation starter.
Should companies face tougher penalties when personal data tied to job, franchise or business applications ends up in hackers’ hands? Let us know by writing to us at Cyberguy.com.

Nintendo’s newest WarioWare is a weirdo smartphone app
Much like WarioWare, Pictonico (which, I admit, I’m not entirely sure how to pronounce) is a collection of microgames that last just a few seconds each. In each round, you play 10 of these in quick succession, and usually you have just enough time to figure out what you actually need to do before moving on to the next thing. You’re given a simple command like, say, “chomp,” and then you have to do something like grab hold of a mouth and make it chew some food. The games are all very silly in often hilarious ways, so you’ll be plucking hair, licking lollipops, and peeling bananas as quickly as you can.
The twist in Pictonico is that the games all use photos on your camera roll to customize the experience. The game pulls faces from photos and slips them into the microgames, so I found myself making my wife chomp down on kebab with a disturbingly large mouth, or rubbing a lamp to see a buff genie version of my 10-year-old pop out. As an example, here is me as a ballerina waiting to get their photo taken:
The game lets you choose which photos you want to appear in the game so things don’t get uncomfortably weird, and it does occasionally pull things that aren’t human faces. At one point I had to match up an image that had been broken up into three parts, and it was a photo I had taken during my time reporting on the Nintendo Museum in Kyoto. Pictonico is a free download on both iOS and Android, but that only gets you access to a demo version; to play the full thing, which includes 80 different minigames, you have to buy two content packs priced at $7.69 and $5.99 each.
