The search for Nancy Guthrie, the 84-year-old mother of "Today" show co-host Savannah Guthrie, has stretched into its sixth week with investigators turning to genetic genealogy and forensic DNA analysis amid a theory that her abduction was targeted, Pima County Sheriff Chris Nanos said in recent interviews.

Guthrie was last seen at her home in the Catalina Foothills area of Tucson on the evening of January 31, 2026, after being dropped off by family. She failed to appear at church the next day, February 1, prompting a missing person report around noon. Authorities quickly classified the case as a possible kidnapping, citing drops of her blood found on the front porch and signs of forced entry or struggle inside the residence.

No arrests have been made, and no confirmed sightings of Guthrie have surfaced since her disappearance. The FBI joined the investigation early, offering a $50,000 reward for information leading to her recovery or the arrest and conviction of those responsible. A dedicated team from the sheriff's homicide division continues collaborating with federal agents.

In a Thursday interview with NBC Nightly News, Sheriff Nanos described the incident as targeted, stating investigators "believe we know why he did this" and that the home was specifically selected. He stopped short of full certainty, adding, "We're not 100% sure of that, so it would be silly to tell people, 'Yeah, don't worry about it, you're not his target.'" Nanos emphasized the possibility that the perpetrator "absolutely could strike again," urging community vigilance without releasing specific motive details to protect the investigation.

The case has drawn intense media attention due to Savannah Guthrie's prominence. The family has cooperated fully, with Savannah publicly pleading for information and sharing emotional appeals. Authorities cleared family members, including siblings and spouses, of any involvement early on.

Key evidence includes surveillance footage from Guthrie's Nest doorbell camera showing a masked man—described by the FBI as male, about 5-foot-9 to 5-foot-10 with an average build—on the porch the night of the disappearance. He carried a 25-liter Ozark Trail Hiker Pack backpack. Additional images recovered by the FBI from neighborhood cameras in the days leading up captured the same or a similar figure without the backpack, suggesting prior reconnaissance.

Recent developments center on DNA. Foreign DNA was found inside the home, described as a mixed sample complicating analysis. Forensic genetic genealogist CeCe Moore, who has aided in over 300 cases, appeared on NewsNation's "The Truth of the Matter" podcast, explaining the challenges of mixed profiles and the potential for saliva or other trace evidence left by the suspect. Moore highlighted how genetic genealogy could generate leads even from partial or degraded samples, though she cautioned that results depend on database matches and investigative follow-up.

A damaged utility box near the home is under review, potentially linked to efforts to disrupt security systems. Neighbors reported internet glitches in the area on the night of February 1, prompting FBI agents to canvass the neighborhood in early March asking about connectivity issues that evening.

Tip volume to the FBI line initially surged but has tapered, officials said, though the public is urged to continue calling with any information. Alleged ransom notes demanding bitcoin were sent to media outlets shortly after the disappearance, referencing specific home details and Guthrie's clothing, but their authenticity remains unconfirmed publicly.

The investigation has faced scrutiny over pacing and communication. Former FBI officials and analysts have described elements as "extremely confusing" or "very odd," noting the rarity of abductions involving elderly victims—less than 0.2% of reported cases involve women in their 80s—and the absence of a vehicle of interest or immediate suspect identification in an era of widespread surveillance.

Mental health experts note the profound trauma of ambiguous loss for families, where uncertainty freezes grief. Savannah Guthrie returned to the "Today" set briefly in early March, though not on air, signaling ongoing family strain.

As the case enters day 44, search efforts persist with no major breakthroughs announced. Sheriff Nanos expressed continued "faith and hope" that Guthrie remains alive, citing no proof of death despite the passage of time. Her need for daily medications adds urgency to the probe.

Community members in the Catalina Foothills have mobilized, posting flyers and sharing tips. A neighbor recently recounted seeing a "strange man" in the area weeks before the disappearance, providing a description to investigators.

The high-profile nature amplifies calls for resolution, with experts comparing it to other unusual missing persons cases while underscoring its unique aspects: an elderly victim, celebrity connection, targeted elements and persistent DNA leads.

Authorities stress that every tip matters as they pursue genetic genealogy avenues and re-examine evidence. Until concrete progress emerges, the mystery of Nancy Guthrie's fate continues to grip the public and her family.
