Authorities are searching for Nancy Guthrie, the mother of NBC's Savannah Guthrie, who has been missing since January 31st from her home in Arizona. The last reported sighting of the 84-year-old was at her residence in Catalina Foothills. Her last Facebook activity was a few days prior, raising concerns among family and investigators.

Sheriff Chris Nanos of Pima County confirmed that search and rescue operations, including air and ground efforts, are underway. Due to Guthrie’s age and health, a homicide team is assisting the investigation. Her recent social media activity, which included political content, is also being examined as part of the ongoing probe.

This situation has drawn considerable attention, particularly given Savannah Guthrie's high profile in the media. The investigation's focus on a homicide team suggests the seriousness of the situation. Further updates are expected as the search continues, with the public urged to provide any relevant information.
