Nancy Guthrie, the 84-year-old mother of Today co-host Savannah Guthrie, remains missing after six weeks of searching. Digital forensics experts now highlight a crucial clue investigators may be overlooking. Her hearing aids could unlock everything about her location and potential whereabouts.
🔥 Quick Facts
- Missing Since: January 31, 2026, from her Tucson, Arizona home
- Key Device: Hearing aids paired with her phone via Bluetooth may track location
- Expert Opinion: Digital forensics expert Heather Barnhart says hearing aids could be “key to everything”
- Reward Offered: Family offering up to $1 million for information leading to her safe return
How Hearing Aids Could Solve the Mystery
Heather Barnhart, a digital forensics expert with SANS Technology Institute and Cellebrite, revealed critical information during a Tuesday, March 10 appearance on Crime Stories with Nancy Grace. Nancy’s hearing aids pair with her phone through Bluetooth connectivity, creating a potential digital trail. The expert explained that hearing aids function similarly to AirPods, allowing users to listen to music, make calls, and receive FaceTime communications through the connected device.
This Bluetooth pairing creates what investigators call a “database on her phone” that could show her last known location. Examiners analyzing Nancy’s phone may be able to access this data if the pairing was active when she disappeared. The timing is crucial, however. The data only works if the hearing aids were powered and paired at the moment of her abduction.

The Two Pairs of Hearing Aids Mystery
A significant discovery emerged during investigation updates. While Nancy left one pair of hearing aids behind at her home, she may have been wearing a second pair when she was taken. This detail transforms the investigation dramatically. If Nancy was wearing the second pair during her abduction, that device becomes a potential tracking device worth its weight in solving the case. Investigators would need to determine which hearing aid model Nancy owned and whether it has location-tracking capabilities through an app or cloud service.
Nancy Grace, host of Crime Stories, emphasized this crucial detail on her show. She noted that the discovery of a possible second pair represents one of the most promising forensic leads discovered since the investigation began. Digital experts worldwide have pointed to this detail as something authorities should prioritize examining.
Technical Limitations and Investigator Strategy
| Factor | Impact on Investigation |
| Phone Location | Left behind at home, limiting direct tracking |
| Bluetooth Range | Required active pairing for real-time location data |
| Battery Status | Lost locations once hearing aid batteries depleted |
| Connected Device | Pacemaker also connected, providing additional data |
A major complication exists in this case. Nancy’s phone, which would be “the key to everything on Nancy’s location,” was left behind at her residence. Without the phone present, investigators cannot access real-time location tracking. However, experts suggest authorities may have recovered last known location data from the hearing aids before their batteries died. Many modern hearing aid models include a `Find My’-type feature accessible through smartphone apps.
Additionally, Nancy has a medical pacemaker that the investigation discovered contains valuable timing information. The pacemaker pinged and established the likely timeframe of her disappearance. This medical device, combined with hearing aid data, creates a more complete digital picture of events.
“Her phone is tied to those hearing aids and tied to her pacemaker. The fact that her phone is left behind, I’m sure investigators looked to see if they could ping that and get a location. And they either did and they’re holding that close to them, or they fell short.”

What Investigators Know and What Remains Unknown
The Pima County Sheriff’s Department and the FBI have been actively investigating Nancy’s disappearance since February 1. Authorities have focused on surveillance footage showing a masked individual at her door and evidence suggesting an abduction rather than a voluntary departure. DNA evidence not belonging to Nancy was discovered at the scene, narrowing investigator focus to specific suspects.
However, a critical question remains unanswered. Did investigators successfully locate and retrieve location data from Nancy’s second pair of hearing aids? If they recovered last-known coordinates before the batteries depleted, they may be withholding this information as part of their investigative strategy. Federal agents often keep significant evidence private to avoid compromising the case or alerting suspects to their actual investigative progress.
Could This Lead Finally Bring Nancy Home?
The hearing aid discovery offers investigators a potential path forward that didn’t exist with traditional missing person protocols. Modern wearable technology has transformed criminal investigations, yet many cases still overlook these digital breadcrumbs. Nancy’s family, including her daughter Savannah Guthrie, has maintained that they believe Nancy is “still out there.” The family continues offering a $1 million reward for information leading to her safe return. Will examining the second pair of hearing aids finally provide the breakthrough investigators desperately need?
