As the search for Nancy Guthrie entered its third week, authorities reportedly resorted to using a high-tech Bluetooth scanner in hopes of detecting her pacemaker signal.
According to NewsNation, law enforcement has used a “signal sniffer” attached to one of the skids of a Pima County Arizona Sheriff Department helicopter.
Last week, NewsNation senior national correspondent Brian Entin reported spotting one of the helicopters with the device near Nancy’s residence.
These helicopters fly low at a slow pace, scanning for signals from Bluetooth devices like AirPods and pacemakers.

Meanwhile, former FBI special agent Maureen O’Connell noted that the authorities are likely utilizing a variety of technologies in the search for Savannah Guthrie’s mother.
“With regards to this particular tool ⦠I do know that the pacemaker sends off a very short-distance alert, or whatever, so theyâre going to have to get really close,” O’Connell told NewsNation.
Digital forensics examiner Karl Epps told KOLD that the pacemakerâs disconnection likely does not mean Nancyâs heart stopped, but instead suggests she may have moved beyond the Bluetooth range of her phone.
“You can liken it to devices that we all have. If you leave your AirPods sitting somewhere and you walk far enough away from them, which isnât too far, they will disconnect, and you will get a message,” Epps told the outlet.
Epps also noted that the pacemaker relies on near-field communication, meaning it must be in close proximity to another device to establish a connection.
“Very unlikely we are able to get a signal from it unless we are right on top of it,” he added.
Nancy’s pacemaker was disconnected from her phone at 2:28 a.m. on the night she went missing.
