Federal and local authorities confirmed that search teams operating near the Arizona–Mexico border have recovered two items believed to be connected to the disappearance of Nancy Guthrie: a cardiac pacemaker transmitter associated with her implanted medical device and a satellite communication phone.
The discovery was made in a steep desert ravine several miles north of the international boundary. Officials described the terrain as remote and difficult to access without deliberate effort.
According to investigators, the location was identified after analysts detected irregular electronic signal data logged earlier in the search. A coordinated task force used rope systems and ground-mapping equipment to descend into the ravine.
Both devices were reportedly found partially concealed beneath loose rock and scrub brush, leading authorities to believe they may have been intentionally placed rather than accidentally lost.
Forensic specialists have secured the pacemaker transmitter for laboratory examination. Analysts are working to determine whether the unit was manually activated, tampered with, or deliberately separated from its monitoring system in an attempt to generate misleading telemetry.
The satellite phone — capable of operating beyond conventional cellular networks — has been submitted for digital forensic extraction. Investigators are attempting to recover call logs, stored contacts, and GPS routing history.
Authorities also confirmed the recovery of a handwritten note at the scene. While its contents have not been publicly disclosed, sources describe the message as confrontational and directed toward investigators. The document is undergoing handwriting comparison, fingerprint analysis, and fiber testing.
Officials emphasized that the discovery does not confirm Nancy’s physical presence at the ravine. Investigators are considering the possibility that the devices were staged to redirect resources toward the border region. Due to the proximity to Mexico, federal agencies are conducting intelligence coordination and cross-border data reviews.
No arrests have been announced. Authorities state that the investigation remains active, with forensic, digital, and intelligence analyses ongoing.
