The investigation into the disappearance of Nancy Guthrie, the 84-year-old mother of NBC "Today" show co-host Savannah Guthrie, stretched into its 37th day on March 8, 2026, with federal agents pursuing leads suggesting the abductor may have used a high-tech Wi-Fi jammer to disable home security systems and internet connectivity the night she vanished.

Nancy Guthrie was reported missing Feb. 1 from her home in the Catalina Foothills area outside Tucson after being taken against her will in the early morning hours of Feb. 1. Authorities believe the incident occurred sometime after she was last seen around 9:45 p.m. on Jan. 31. A surveillance video released by the FBI shows a masked figure approaching her front door, and blood was found on the porch, indicating possible violence during the abduction.

The Pima County Sheriff's Office and FBI task force continue to treat the case as a kidnapping, with no arrests announced and no confirmed suspect identified. On Thursday, March 5, and into the weekend, investigators returned to the neighborhood, questioning residents about internet outages or disruptions on the night of the disappearance. Multiple reports from NBC News and Fox News indicate agents are exploring whether a device known as a Wi-Fi jammer — which can block wireless signals and interfere with cameras, smart home systems and internet-based alerts — was deployed to facilitate the crime undetected.

Sheriff Chris Nanos has described the investigation as active and progressing, telling outlets that a dedicated task force of local deputies and federal agents is working full-time on leads, forensic analysis and tip review. In a recent interview, Nanos emphasized that while DNA evidence from the scene — including samples not matching family members or close contacts — has been collected and submitted for genetic genealogy testing, results could take months due to lab backlogs and mixed profiles.

A pair of black gloves discovered about two miles from the home drew attention earlier in the probe. Authorities traced them to a local restaurant employee with no connection to the case, clearing that avenue. The $1 million reward offered by the family for information leading to Nancy's recovery or the suspect's identification remains in effect, with Savannah Guthrie making repeated public appeals, including videos featuring her siblings Annie and Camron.

Savannah Guthrie returned to the "Today" studio in New York City on March 5 after spending time in Arizona, expressing gratitude to colleagues and reaffirming her commitment to the search. In statements, she described her mother as "taken in the dark of night from her bed" and urged anyone with information to contact authorities. The family has leaned on faith, with their pastor from Good Shepherd New York sharing messages of hope and prayer during interviews.

No ransom has been paid, and early reports of deadlines or demands have not led to breakthroughs. The sheriff has cleared all immediate family members as suspects, calling them cooperative victims in the ordeal. Investigators continue sifting through surveillance footage, physical evidence and tips submitted via the FBI tip line.

The case has drawn national attention due to Savannah Guthrie's prominence, fueling discussions about ambiguous loss — the grief experienced when a loved one is missing without closure — and the emotional toll on families. Experts note that prolonged uncertainty can "freeze" the grieving process, as seen in similar high-profile disappearances.

As of March 8, no new major developments were reported over the weekend, though the FBI's focus on potential technological interference has renewed speculation about the sophistication of the perpetrator. Neighbors described investigators' door-to-door efforts as thorough but quiet, with questions centered on Wi-Fi reliability that fateful night.

The investigation highlights challenges in solving abductions involving elderly victims in suburban settings, where rapid response is critical but evidence can be limited. Authorities urge the public to remain vigilant and report any suspicious activity or information, no matter how small.

Savannah Guthrie has balanced her on-air duties with advocacy for her mother's safe return, thanking supporters while emphasizing ongoing hope. The family continues to hold prayer vigils and share updates through media channels.

As day 37 dawns, the search for Nancy Guthrie persists amid a blend of high-tech investigative angles and traditional legwork. Officials express cautious optimism that accumulating leads will yield answers, though time remains a critical factor in such cases.

The broader community in Tucson and beyond watches closely, with many expressing solidarity through social media campaigns and local support efforts. Whether the Wi-Fi jammer theory or DNA leads provide the breakthrough remains to be seen, but the commitment to bringing Nancy home endures.
