TUCSON, Arizona – In a dramatic escalation in the high-profile disappearance of 84-year-old Nancy Guthrie, mother of TODAY show co-anchor Savannah Guthrie, investigators are urgently analyzing a key phone call that could hold the breakthrough the case desperately needs. Sources close to the investigation reveal that this call, linked directly to the circumstances surrounding Guthrie’s vanishing on February 1, 2026, has potentially been geolocated – sending shockwaves through law enforcement and the public alike.

Nancy Guthrie was last seen on the evening of January 31 when her son-in-law dropped her off at her Tucson home. She failed to appear at church the next morning, prompting family members to rush over and discover her missing. Her personal belongings, including her phone, remained inside the residence, but her pacemaker app disconnected from her device around 2:28 a.m. on February 1 – a chilling detail amid reports of motion detected shortly after her doorbell camera was tampered with.

The FBI and Pima County Sheriff’s Department have been flooded with thousands of tips – over 20,000 calls in recent days – following the release of disturbing doorbell footage showing a masked, armed man, described as 5’9″ to 5’10” with an average build, wearing a black Ozark Trail backpack. The suspect appeared to disable the camera around 1:47 a.m., heightening suspicions of a forced entry or botched burglary gone horribly wrong. Authorities believe this may have been an intended robbery that spiraled into abduction, with hopes still alive that Guthrie could be found safe.

Now, this new phone call under scrutiny represents a potential game-changer. Digital forensics experts have long emphasized the value of cell tower data and ping records from devices in the area during the critical overnight hours. With sparse activity around 2 a.m., pinpointing unusual signals could narrow suspects dramatically. If the call has indeed been traced – possibly revealing a location far from the home or tied to suspicious activity – it could align with earlier unconfirmed reports of anomalous phone pings miles away, fueling speculation about movement after the disappearance.

The investigation has already seen major developments: DNA recovered from a glove found near the property matching one worn by the porch suspect, ongoing searches along roadways, and even fake ransom attempts that led to arrests unrelated to the core crime. Savannah Guthrie has made emotional public pleas, urging anyone with knowledge to come forward and insisting “it’s never too late to do the right thing.”

As the search enters its third week, the $100,000 FBI reward remains active, and the tip line (1-800-CALL-FBI) continues to ring off the hook. This latest phone call analysis injects fresh urgency – could it finally reveal where Nancy Guthrie was taken, or who might be responsible? The family, the nation, and investigators wait with bated breath for confirmation. Every second counts in this race against time.
