Months after 84-year-old Nancy Guthrie vanished from her Tucson home, the FBI is turning to advanced DNA technology in a renewed push for a breakthrough. Investigators are analyzing what has been described as “potentially critical” genetic material recovered from the Catalina Foothills residence where the mother of Today show co-host Savannah Guthrie was last seen.

The sample was not newly collected. It was obtained earlier in the investigation and later sent by a Florida laboratory that works with the Pima County Sheriff’s Department to the FBI for more sophisticated testing. Agents are applying newer analytical methods in the hope of extracting clearer information from the evidence.

Authorities have confirmed that the DNA recovered from the home came from more than one person. In addition to the FBI’s work, as many as five other laboratories across the country are also dedicating resources to the case. It remains unclear whether those labs are examining the same material or additional samples.

A Case That Has Moved Slowly
Nancy Guthrie was last seen on the evening of January 31, 2026, after a family member dropped her off at her home following dinner. She was reported missing the next morning. Investigators believe she was abducted in the early hours of February 1. Security footage showed a masked figure disabling her Nest doorbell camera. Blood was found on the front porch, and her pacemaker monitoring system disconnected around the same time.

Despite the involvement of roughly two dozen investigators from the Pima County Sheriff’s Department and the FBI, progress has been limited. The case has generated intense public interest, multiple ransom notes of varying credibility, and a combined reward of more than $1.2 million. Yet no arrests have been made, and Nancy has not been found.

The FBI declined to comment when asked about the current DNA analysis. Officials have similarly remained tight-lipped about many other aspects of the investigation, citing the need to protect ongoing work.

Why DNA Matters Now
In missing-person and abduction cases, DNA can serve as a crucial link between a crime scene and a potential suspect. Advanced testing techniques sometimes allow laboratories to develop usable profiles from samples that earlier methods could not fully interpret. Investigators appear to be hoping that the current round of analysis will yield something actionable after months of limited leads.

At the same time, the presence of DNA from more than one person at the home complicates the picture. Distinguishing between individuals who had legitimate reasons to be there and anyone who may have been involved in the abduction is a careful and time-consuming process.

Broader Context of the Investigation
The early stages of the case were marked by conflicting information and a series of notes claiming knowledge of Nancy’s whereabouts. Some of those communications were later determined to be false. Others were taken more seriously by investigators and the family. Savannah Guthrie has said publicly that she believes at least two of the notes received by the family were authentic.

Criminal profilers and former investigators have offered differing interpretations of the evidence, including the behavior of the masked figure seen on camera and the nature of the ransom demands. Local and federal authorities have continued to canvass the neighborhood, examine digital records, and follow public tips, but a clear resolution has remained elusive.

Nancy Guthrie was 84 years old when she disappeared. She lived alone in a quiet residential area and was known to her neighbors as a friendly and independent presence. Her family has expressed both determination and exhaustion as the months have passed without answers.

What Comes Next
The decision to subject the existing DNA evidence to more advanced testing suggests investigators still see potential value in material collected early in the case. Whether that analysis produces a usable lead remains to be seen. In the meantime, the investigation continues with a significant number of personnel still assigned and multiple laboratories contributing resources.

Anyone with information about Nancy Guthrie’s disappearance is urged to contact the FBI at 1-800-CALL-FBI or submit tips anonymously through local channels. The reward for information that leads to her recovery or the identification of those responsible remains in place.

For the Guthrie family and the wider public that has followed the case, each new technical effort brings a measure of hope — and a reminder of how much is still unknown.
