Authorities in Arizona are using data from an Apple Watch tied to Nancy Guthrie to narrow the timeline of her disappearance. Guthrie is the 84-year-old mother of NBC’s Today co-anchor Savannah Guthrie. She was reported missing from her Catalina Foothills home near Tucson after failing to show up for church on Sunday, February 1, 2026.
Officials say the Apple Watch that belonged to Nancy was linked to her implanted pacemaker. That device was syncing with her medical data before it suddenly stopped in the early morning hours of February 1. Police believe the loss of that connection helps pinpoint when she was taken from her home.

Arizona law enforcement has treated her disappearance as a possible kidnapping. Investigators have focused on timelines based on technology signals, including the last known Apple Watch and pacemaker sync. This detail has become one of the key pieces in the ongoing inquiry.
Apple Watch Data Shows
The technical data from the device provides clues in a case with few solid leads. Key points include:
- The pacemaker linked to the Apple Watch lost sync around 2 a.m. local time.
- Both the Apple Watch and her phone were found inside her home when police arrived.
- Investigators are using the sync loss to estimate when she was likely taken.
This type of digital evidence has become more important in missing person cases. Apple Watches can track health data and connectivity. When the pacemaker stopped communicating, it gave officials a rough window of when the incident occurred.
More Investigation Details
Police say they found blood at the home that matched Nancy Guthrie’s DNA. There were also signs of forced entry. Investigators have not named any suspects. They have reviewed neighborhood cameras and searched the broader area without finding her.
Multiple alleged ransom notes have surfaced, with one claiming to reference her Apple Watch and a floodlight at the house. Law enforcement is investigating those messages but has not confirmed their authenticity.
The FBI has joined the case, and a reward of $50,000 is offered for information that leads to locating Nancy Guthrie or an arrest.
Family Response
Savannah Guthrie and her siblings have made public appeals for her return. They have urged anyone involved to make direct contact. Savannah stepped away from her duties on the Today show to focus on the search.
The family and authorities are continuing efforts to find her and bring her home safely. Digital evidence from the Apple Watch and pacemaker remains one of the tools guiding those efforts.
