TUCSON, Ariz. (AP) — It’s been more than a week since Nancy Guthrie, the mother of 'Today' show host Savannah Guthrie, disappeared from her home in Tucson, Arizona. Authorities believe the 84-year-old was kidnapped, and the investigation into her disappearance is ongoing.

Local law enforcement is actively examining ransom notes and gathering evidence, but they have yet to identify a suspect. Over the weekend, officers returned to Nancy Guthrie's residence and surrounding neighborhood to continue their search.

The Disappearance

Family members reported that they last saw Nancy Guthrie after dropping her off at home after dinner on January 31. Concern grew when she was absent from church the following day, prompting her family to check on her and subsequently report her missing. Given her age and health condition, including a pacemaker that requires daily medication, there is increasing anxiety regarding her well-being.

Current Evidence

Authorities suspect that Nancy was taken from her home, as DNA evidence found on her porch matched her own. Additionally, investigators have discovered that her doorbell camera was disconnected just before her disappearance, leaving them unable to retrieve critical surveillance footage. Pima County Sheriff Chris Nanos confirmed they are exploring all options to recover those images.

Ransom Notes

Multiple media outlets received ransom notes related to Nancy Guthrie's case. After some investigation, one of the notes was confirmed to be a hoax; however, law enforcement is taking the remaining correspondence seriously. Details in the notes allegedly included demands for money, with specific references tied to items at Nancy’s home.

Family’s Plea for Help

As fears for Nancy’s health escalate, her family has made public appeals, expressing their deep concerns and asking her captors for proof of her well-being. Savannah Guthrie has shared emotional messages recorded for the kidnapper, emphasizing that they need reassurance that their mother is alive.

The FBI has stepped in, offering a reward of $50,000 for any information concerning Nancy’s whereabouts. In a recent interaction, President Trump assured the family that federal authorities were mobilizing to assist in the investigation.

Historical Context

This case joins a list of high-profile abductions that have captured national attention, reminiscent of past notorious kidnappings in the U.S. The public continues to rally behind the family, hoping for the safe return of Nancy Guthrie.
