TUCSON, Ariz. — A week has passed since Nancy Guthrie, the mother of NBC's 'Today' show host Savannah Guthrie, disappeared from her home in Tucson, Arizona, in what investigators believe to be a kidnapping.

Authorities have been examining ransom notes and searching the area near Nancy's home. According to family reports, Nancy was last seen on January 31 when they dropped her off after dinner. The following day, her family became concerned when she did not attend church and contacted law enforcement.

Nancy, who is 84 years old, relies on daily medication and has a pacemaker, raising urgent concerns about her health as each day passes without contact.

The Search Efforts

Investigators have determined that Nancy was most likely taken from her home. Blood matching Nancy’s was found on her front porch, and further analysis revealed that her doorbell camera was disconnected shortly after her disappearance.

Pima County Sheriff Chris Nanos reported that investigators are still trying to recover footage from the disconnection, despite a lack of an active subscription to the service. Meanwhile, the community has rallied, with local residents cooperating with police and allowing for neighborhood searches.

Ransom Notes

Multiple media organizations received ransom notes, some of which have been identified as false while others remain under serious investigation. Details from the notes included demands for money and references to specific items at Nancy's home.

The sheriff confirmed that the situation is taken seriously and ongoing efforts are in place to decipher the validity and details within each note.

Family Appeals

The family has expressed mounting concern over Nancy's health and is actively appealing for her safe return through social media, with Savannah Guthrie urging whoever is responsible to provide proof of her mother’s well-being.

In recent remarks, Savannah described her mother as a loving and kind individual and made a heartfelt plea to her mother’s abductor, stating they will not stop searching until she is safely returned.

Federal Involvement

The investigation has drawn national attention, including involvement from federal authorities. The FBI has offered a reward for any information leading to Nancy's safe return.

The kidnapping has resonated with the public, reminiscent of other high-profile abduction cases in the country. As authorities continue their investigation, the family and community remain hopeful for a positive outcome.
