TUCSON, Ariz. (AP) — The investigation into the disappearance of Nancy Guthrie, the mother of 'Today' show host Savannah Guthrie, intensifies as it reaches a week since her reported kidnapping in Arizona. Authorities continue to delve into ransom notes purportedly connected to the case while searching for more evidence.

Officers recently returned to Nancy's residence in Tucson to further investigate her upscale neighborhood, where the 84-year-old was last dropped off by family after a dinner on January 31. When she failed to attend church the next day, her family reported her missing, raising alarms given her medical condition, which includes the need for a pacemaker and daily medication.

Investigation Details

Evidence collected by law enforcement has revealed blood on Guthrie’s front porch, which matches her DNA. Investigators face challenges recovering video from Nancy's disconnected doorbell camera; they are seeking access despite her lack of an active subscription for the service. Sheriff Chris Nanos acknowledged the frustrations surrounding the technology's limitations in capturing critical moments.

Ransom Notes and Public Appeals

Several media organizations reported receiving ransom notes that detailed demands for money, with one note leading to an arrest when it turned out to be a false alarm. However, the authorities remain vigilant as reports of another message tied to the case emerge. Family members worry for Nancy's health, prompting them to record emotional video messages pleading for proof of her safety.

‘We won’t rest until we’re all together again,’ Savannah Guthrie expressed in a heartfelt appeal, highlighting her mother’s vibrant spirit and plea for her return. The FBI has stepped in with a reward of $50,000 for any information leading to Nancy's safe return.

Government Support and Community Involvement

In a show of support, President Donald Trump contacted Savannah Guthrie and has committed federal resources to assist in the investigation. As the search continues, the local community has actively participated by sharing information and opening their properties for potential evidence gathering. The family’s emotional distress resonates throughout the community, aiming to bring Nancy home safely.

As the investigation develops, both law enforcement and the Guthrie family urge anyone with information regarding Nancy’s whereabouts to come forward.
