Investigators Use Pacemaker 'Signal Sniffer' and Trace Ozark Trail Backpack in Nancy Guthrie Kidnapping Probe
Investigators—who say they believe 84‑year‑old Nancy Guthrie was kidnapped—are using a custom “signal sniffer” built by former NSA hacker David Kennedy to detect Bluetooth Low Energy pings from her pacemaker (which stopped communicating with her phone app at 2:28 a.m.), mounting the device on a low‑flying helicopter and exploring wider drone deployment after tests showed an amplified pacemaker signal can be detected well beyond the device’s nominal 10–15‑foot range. At the same time the FBI has identified the porch suspect as carrying a black 25‑liter Ozark Trail Hiker Pack sold exclusively at Walmart and is working with the retailer to trace purchases and review surveillance, while agents pursue DNA from a roadside glove, evaluate alleged ransom communications and have increased the reward for information.
📌 Key Facts
- Nancy Guthrie, 84, was last seen the evening of Jan. 31 in Tucson; investigators say she was likely taken from her home, blood on her front porch has been DNA‑matched to her, and she requires daily medications and a pacemaker.
- A consolidated timeline from investigators shows Guthrie was dropped home at ~9:48 p.m.; the garage closed ~9:50 p.m.; the doorbell camera was disconnected ~1:47 a.m.; the home security system logged a motion event ~2:12 a.m.; and Guthrie’s pacemaker app stopped communicating ~2:28 a.m.
- The FBI and Pima County released infrared/porch images of a masked, apparently armed person tampering with the front‑door camera; the bureau later described the individual as roughly 5'9"–5'10" with an average build carrying a black 25‑liter Ozark Trail "Hiker Pack," and the family says they do not recognize him.
- Investigators recovered multiple gloves (one found about two miles from the home) and other unidentified DNA from Guthrie’s property; a preliminary DNA profile from the roadside glove produced an unknown‑male profile, CODIS produced no match, and law enforcement is pursuing investigative genetic genealogy (IGG) and CODIS entry while awaiting final confirmations.
- Authorities are working directly with Walmart and reviewing SKU‑level sales records and in‑store surveillance to trace purchases and video for the Ozark Trail 25‑liter backpack (a Walmart‑exclusive item seen on the porch footage) and other likely Walmart gear (mask, clothing, holster) to generate leads.
- Investigators are using a custom 'signal sniffer' to detect Bluetooth Low Energy transmissions from Guthrie’s pacemaker (which emits periodic signals); the device—developed by cybersecurity specialist David Kennedy—has been amplified and deployed on a helicopter, and officials have discussed expanded drone use to search wider areas.
- Multiple alleged ransom communications have been sent to media outlets and the family; the Guthrie children have posted videos saying they will pay for their mother’s safe return, but the FBI is vetting the messages’ authenticity, warns that deepfakes complicate proof‑of‑life verification, and some third‑party emails (including TMZ‑linked claims) have been treated skeptically as possible scams.
- The case is a large, multi‑agency operation (hundreds of detectives and FBI specialists assigned) that has generated thousands of public tips (the FBI has received >13,000; the sheriff’s office has taken >18,000 calls) and an increased FBI reward now up to $100,000; despite extensive searches, forensic work, a towed vehicle and executed warrants, no one is in custody and the investigation remains active.

- Investigators are using a custom 'signal sniffer' device, invented by former NSA hacker David Kennedy, to detect Bluetooth Low Energy signals from Nancy Guthrie’s pacemaker.
- Kennedy says Guthrie’s pacemaker was disconnected from her phone’s app at 2:28 a.m., and the device emits a Bluetooth Low Energy signal every 2–3 minutes within a 10–15‑foot radius.
- By adding amplifiers and high‑gain antennas, Kennedy has demonstrated the signal can be detected from roughly 800 feet away, and law enforcement has already flown a helicopter at low altitude with the sniffer mounted to begin searching for the signal.
- Kennedy says a large‑scale search using 50–60 drones equipped with the sniffer could cover a 120‑square‑mile area in days to two weeks, but notes agencies don’t yet have that drone infrastructure in place.
- Tucson gun shop co-owner Phillip Martin says an FBI agent came in with three pages listing roughly 18–24 named individuals with photos and asked him to check whether any had bought a firearm at his store within the past year.
- Martin reports he ran each surname through his shop’s electronic records and found no matches for gun purchases during that period.
- Martin says the agent indicated investigators planned to visit additional area gun stores to see whether anyone on the list had recently acquired a weapon.
- Pima County Sheriff Chris Nanos explicitly denies that authorities have narrowed the suspect pool to around 40 individuals, saying investigators have not focused on a specific group despite online claims.

- FBI clarifies that the suspect’s face covering is believed to be black, with its lighter appearance in Nest footage attributed to infrared imaging.

- The profile is undergoing quality-control review before being uploaded to CODIS, indicating an imminent search against national DNA databases.
- An internal law-enforcement source disputes new media reports that investigators now think Guthrie’s disappearance was a 'burglary gone wrong,' saying that is not the unit’s working theory.

- A Miami‑area active‑duty police officer, speaking anonymously, has identified the suspect’s holster in the Nest doorbell video as a Strategy brand large‑frame revolver hip holster sold at select Walmart stores for about $10.
- Walmart’s online inventory shows that specific holster in stock at only a handful of Tucson‑area stores, suggesting a relatively small pool of local purchasers.
- The holster is designed for 4–6.5‑inch revolvers and right‑hand use, but the gun visible in the video appears to be a Walther‑style semiautomatic pistol, an unusual pairing investigators may be able to exploit.
- The suspect’s backpack is identified as an Ozark Trail 25‑liter model sold exclusively at Walmart, tightening the focus on the chain for multiple pieces of the suspect’s gear.
