TUCSON, Ariz. — More than 70 days after 84-year-old Nancy Guthrie vanished from her Catalina Foothills home, authorities confirmed Friday they are investigating fresh ransom-style notes received by media outlets, including TMZ, even as the high-profile abduction case remains without arrests or confirmed sightings of the mother of NBC "Today" show co-anchor Savannah Guthrie.

The latest communications, reportedly delivered around April 6 — the same day Savannah Guthrie returned to the anchor desk — claim knowledge of Guthrie's whereabouts or body and demand Bitcoin in exchange for information. TMZ founder Harvey Levin described the notes as potentially intended to torment the family rather than provide verifiable proof of life, though their authenticity has not been publicly verified by law enforcement. This marks at least the third set of such demands since the disappearance, with earlier notes also referencing cryptocurrency payments.

Pima County Sheriff Chris Nanos and the FBI have not commented directly on the newest letters but reiterated that the investigation remains active and classified as an abduction. Blood matching Guthrie's DNA was found near her doorstep, doors were left propped open, and her phone, wallet and keys were left behind, supporting the theory she was taken against her will in the early morning hours of Feb. 1 after returning from a family dinner on Jan. 31.

Savannah Guthrie made an emotional return to the "Today" show on April 6, opening the broadcast with a quiet "It is good to be home" while wearing a yellow dress symbolizing hope for missing persons. Colleagues and fans outside the studio greeted her with yellow ribbons. She has not addressed the case on air but previously described the family's initial panic, including frantic calls to every local hospital in hopes their mother had suffered a medical episode rather than foul play.

The case has drawn intense national attention, with the family offering a $1 million reward — supplemented by $100,000 from the FBI — for information leading to Guthrie's location or the arrest and conviction of those responsible. Tips have numbered in the thousands, though officials say the volume has tapered in recent weeks.

Recent developments include renewed scrutiny of a vacant rental property next door to Guthrie's home, which investigators believe may have served as a surveillance point for monitoring her routines. Sheriff Nanos previously confirmed authorities are examining possible suspicious activity at Guthrie's residence as early as Jan. 11, weeks before the abduction, based on FBI analysis of digital evidence and equipment.

DNA evidence recovered from the scene and nearby items, including a glove found miles away, has undergone extensive testing. Some samples led to dead ends, such as a restaurant worker unrelated to the case, but renowned genetic genealogist CeCe Moore and other experts have urged investigators to revisit the home with newer technology that could yield breakthroughs in identifying unknown profiles.

Internet outages reported by neighbors on the night of the disappearance have also been re-examined, with FBI agents canvassing the area for additional footage or witness accounts. A doorbell camera captured a masked individual tampering with it shortly before or during the incident.

Experts remain divided on the motive. Some, including former investigators, describe it as a targeted abduction that may have gone wrong, possibly involving multiple people given the logistics of removing an elderly woman without immediate detection. Others suggest the ransom demands could be opportunistic or even hoaxes designed to exploit the family's pain. A former FBI agent told outlets that the "walls are closing in" on those responsible, citing mounting pressure from public attention, the reward and sustained law enforcement resources.

Guthrie, a religious mother of three known for her independence, had no known enemies or history that would explain a random attack. She was last seen in her pajamas without shoes or medication, adding to the family's distress and raising concerns about her health during any prolonged captivity. Her pacemaker reportedly disconnected from her phone around 2:30 a.m., consistent with the abduction timeline.

The search has involved thousands of law enforcement officers, federal agents and volunteers scouring desert terrain, with drones, K-9 units and extensive neighborhood canvassing. Despite the effort, no credible sightings or breakthroughs have been announced publicly in recent weeks. The home has been returned to the family after thorough processing, though some experts advocate for another sweep with advanced forensic tools.

Savannah Guthrie has spoken in interviews about the "chaos and disbelief" of those first hours, the family's desperate hope that turned to dread, and the emotional toll of not knowing. In one video message, she pleaded directly with anyone holding information to come forward. Her return to work has been framed as a step toward normalcy while the investigation continues behind the scenes.

Public speculation has ranged widely, including unverified claims in the latest notes that Guthrie may have been taken to Mexico or that she is no longer alive. Authorities have cautioned against relying on unconfirmed communications and urged anyone with legitimate tips to contact the FBI tip line or Pima County Sheriff's Department anonymously.

As the case stretches into its third month, the emotional strain on the Guthrie family is evident. Savannah has acknowledged being forever changed by the uncertainty. Prayer vigils, social media campaigns and yellow ribbon displays continue in Tucson and beyond, with supporters expressing both hope for a miracle and a desire for answers.

The investigation has faced some criticism over initial handling and resource allocation, though Sheriff Nanos has defended his department's efforts and called for the captor to release Guthrie if she is still alive. He has emphasized that the case remains a top priority.

For the broader community, the abduction has heightened awareness of home security in even affluent neighborhoods. Residents have installed additional cameras and discussed neighborhood watch programs.

Nancy Guthrie's story has drawn comparisons to other high-profile missing persons cases where prolonged uncertainty tested families and investigators. With no arrests and the trail growing colder by the day, experts stress that tips from the public — even those seeming minor — could prove decisive.

The $1 million-plus reward remains active, and the FBI continues to encourage submissions through its tip line or website. As of Friday, no new suspects have been named, and Guthrie's whereabouts remain unknown.

The family and authorities have pledged to pursue every lead until resolution. Whether the latest notes provide a genuine breakthrough or add to the torment, the search for Nancy Guthrie continues with unwavering determination amid fading public updates and persistent hope.
