Incredible!

Seriously technology is amazing and increasing at rapid speed.

Happy to see it utilized in this case.

From what I understand, this is how the wifi data transmission works but a bluetooth pacemaker checks its sync with a connected device every few minutes or so using short-range radio frequency communication. It's been reported that either the last sync or a failed sync between Nancy's pacemaker and her Apple smartwatch happened at 2:28 AM.

I think it's most likely that she simply moved out of range of her smart watch around that time. It was probably a little earlier by a few minutes since the sync checks only happen on those intervals, not continuously, to save pacemaker battery life. So she could have been removed from the area near her smart phone at 2:24 AM or anytime within those few minutes.

@Fargo was reporting earlier that some pacemakers only check in with their device once a day or even less often. Perhaps there are many different setups varying depending on technology or the patient's details? It doesn't seem like we know enough to say whether NG's would check in every few minutes or once daily or what.

Although, if they are really trying to fly a helicopter over Tucson with a sniffer device, they must at least hope that hers is sending out more frequent attempts to connect.

All MOO

Anyone with more knowledge on the matter have timeframe estimates for “forensics” results. I imagine it varies, but hours, days, weeks?

This article speculates "sometime Saturday" but we will see

"TUCSON, AZ (AZFamily) — The FBI is holding off on providing an update in the Nancy Guthrie case until evidence testing results are returned, a source tells Arizona’s Family true crime correspondent Briana Whitney.

The inside source said that details about Friday night’s operations are being withheld pending those results. Once they come in, expected sometime Saturday, the FBI plans to release new information on the direction of the investigation."

I'm intrigued. I wonder how powerful this signal sniffer is? The pacemaker rf signal is very weak (intentionally; to preserve battery) and only transmits a few feet to your bedside monitor or phone app. I wonder what they have?

Not that the FBI would tell me. IMO

Maybe something on a tether where applicable? IDK

I hope this how she is found.

I agree. I hope we can put this issue to bed. Entry and exit through the garage seems sensible for someone with mobility issues, IMO. I'll explain why.

The route through the garage offers sure footing. The floor is even. The steps into the house from the garage are likely utilitarian, made of concrete or wood, and therefore flat. Electric or electronic doors make them easy to operate. In my opinion, a garage with electronic controls on the doors would be the main entry point for NG. It would offer the surest footing and ease.

The front door route is more demanding. The front walkway is beautiful. Nancy probably used often until a few years ago. It has stairs in 2 places, however. You can see in the Google Streetview images below, a black railing was added to the middle of the lower stairs between 2022 and last November. The addition of a railing indicates Nancy needed more assistance with steps in recent years.

Using the front walkway requires navigating two steps closer to the driveway and another step up into the alcove at the front door. The walkway has an upper section that is brick and the lower section that is stone. The screenshot from last fall highlights the unevenness of the stone section between the driveway and stairs. It appears to be cobbles, IMO, like the surrounding landscaping. A cobble walkway is far more uneven than brick.

In my experience, people with mobility issues prefer a hardpacked or paved surface to an uneven one. Relatives who rely on canes approach brick walkways with caution. I don't think they'd even attempt to negotiate a cobble one.

While the driveway is dirt instead of paved, it is hardpacked and easy to maintain. Both the front door/walkway route and the garage route require using the driveway. The front walk ends at the driveway, not at the street. What appears like it may be a mailbox at the end of the walk in the Nest video is actually the post of the black railing on the steps between the upper and lower sections of the walkway. The front door/walkway route to a waiting car or to the mailbox requires more walking on the driveway than the garage route does.

In summary, my opinion is that the garage route offers the safest and easiest access for someone like NG. My opinion
supports what the family member reported Nancy did on January 31st. The sheriff confirmed the garage door opened at 9:48 and closed at 9:50. The facts, the timeline of occurrences at NG's house that night, have been established by law enforcement based on evidence and analysis.

I hope this comparison of two routes helps those with doubts to understand that common sense supports the evidence established by law enforcement here. Practical analysis makes it reasonable and likely she did, and the investigation establishes she did.

Here's the screenshot of Streetview from Nov. 2025. Note there is a black railing in the middle of the lower set of stairs and the unevenness of the cobble section of the walkway.

The screenshot from Streetview in March 2022 is below. Note the two sets of stairs: by the front entrance and halfway down the walkway toward the driveway.

ETA: eliminating bad breaks and typo

Great points.

Also, in a large house the garage usually leads directly into the kitchen/lived in area of the house, while the front door leads to 'guest' areas such as formal living room, guest bathroom, etc.

I wonder if the SIL is the one that set up for the pool to be cleaned by a new company…

Can you please put a source up for this being a new company?
Thank you

I discussed this early on in one of my posts that I studied pacemakers in a cybersecurity class where the topic was national security. Imagine lots of older congress members, president having pacemakers. The research shows not only are they hackable, but they transmit a pretty far distance a small packet which is purposed for dr offices to be able to send updates to firmware, software, etc. I think I posted if she near a dr office or hospital they might could ping her.

Or … If she did pass, intentionally killed or not, perp could have set her body on fire out in the open desert somewhere (as happened in Ben’s case).

We are truly lucky someone happened upon Ben while his body was still on fire, or I doubt if anyone would have ever found him (or it would have been potentially a very, very long time).

IF perp did this to Nancy, I think it would prove very difficult to locate her. JMO

Of course I hope and pray this is not the case.

Scary thought.

Concerning the signal sniffer. A helicopter isn't going to be able to get within 30 ft in an urban area. Wouldn't a drone be much more effective and less risky?

So they are saying he is the prime suspect but had to release him (for now). It is now commonly known who the registered owner of the Range Rover is.....so maybe existing evidence is weak but they are hoping for more?

They’re saying he was the person of interest. If the car was only sold in the past few days, as someone in this thread speculated (or sleuthed?) earlier, but the cops weren’t aware of that, it might be that the person of interest is now who may have been driving it before it was sold.

Me too! Not just for NG and her family, but just think how that would steer the course of future searches, once it's know that tech works!

Drone would be absolutely perfect for this mission!

Could it include some kind of signal booster or extender?

 

[CandyKiss]

Fox NewsNation is reading our posts (and hopefully other non-news entities). We should be succinct and focused on NG. Keep the eye on the ball.

do you have a copy of the article or video?

Nancy Guthrie: Pool Cleaners Show Up at Her House Amid Police Probe

12:39 PM PT -- Pima County Sheriff Chris Nanos tells TMZ ... the Guthrie family requested the cleaners come by to maintain the pool.

www.tmz.com

"We reached out to the pool company .. they say they've never had a client at that address."

ETA I see I have shocked @BenjaminJAndersonAlly with this post. This is just clarification that a different pool service company was called to clean NG's pool rather than her usual contract.

 

[Jade]

The Apple watch which NG had, has fall protection. It works well and is reliable. JMO

Did her no good off her arm and charging apparently.

All imo

Absolutely, but if you were using one, you might want to tell the public that the sniffer is on a helicopter, so that the perps aren’t on the lookout for a drone!

Not necessarily what I think is happening but JMO either way

 

[barth00]

Very random - just googled and realized most homes in AZ don’t have basements (from the northeast so they are the norm here). If NG were to be alive somewhere, she would have to be somewhere pretty secluded, right? I know much of the populated AZ cities are pretty dense so the risk of neighbors seeing or hearing things would be high? Imo

I guess what I’m trying to say is if she was in someone’s home, unless it is huge and far away from other homes, if she tried to escape or made noise she might easily be heard

 

[NewYork625]

Why didn’t she have a life alert device?

I have a family member who is elderly, disabled, and walks with a cane. She lives alone, and even after falling and not being able to get back up unassisted, and spending many hours on the floor trying to get to where she left her phone (the police needed to break down the door to get to her), insists that she's not "that old" and doesn't need a life alert device
