TLDR
Investigators in Pima County, Arizona, are in their seventh week searching for 84-year-old Nancy Guthrie after her suspected abduction, working with limited video, partial DNA, and other clues while urging the public to share information that could identify a suspect.
Seven weeks after 84-year-old Nancy Guthrie disappeared from her Tucson-area home, investigators say they are still working with a narrow set of confirmed facts. No suspect has been named or arrested. The case now turns on a handful of technical clues and public cooperation.
Guthrie, the mother of “Today” co-host Savannah Guthrie, is believed by investigators to have been abducted from her longtime house in the Catalina Foothills north of Tucson in the early hours of February 1st. The Pima County Sheriff’s Department has described the disappearance as suspicious. Nest doorbell video captured a masked person near the home around the time she vanished, but authorities have not publicly identified the individual. Officials have not released any evidence indicating whether Guthrie is alive.
Key Timeline and Leads
According to Fox News Digital and prior public statements from Sheriff Chris Nanos, Guthrie’s pacemaker last synced via Bluetooth at around 2:30 a.m. on the morning she went missing. Investigators reported finding small blood drops on her front porch, with a trail that extended into the driveway and then stopped. Detectives have collected and reviewed home security footage from the neighborhood, including additional images recovered in recent days that have not been made public.
Investigators have also examined reports of a power or internet disruption in the area around the time of the suspected abduction. Nanos has said the team looked at a nearby utility box that appeared to have been tampered with and ultimately ruled it out as unrelated to the crime.
Forensic Evidence and Its Limits
Inside the home, detectives recovered a mixed DNA sample that was sent to a private laboratory in Florida for advanced analysis, Fox News Digital reported. Federal law enforcement officials told the outlet that the sample produced only a partial profile, which was not sufficient for entry into the FBI’s CODIS database or for investigative genetic genealogy.
A partial profile can still help investigators exclude potential suspects, but it provides less power to generate a cold hit compared with a full DNA profile. The lack of a match in existing databases, combined with the mixed nature of the sample, has left investigators dependent on continued lab work and additional physical evidence.
Warnings, Reward, and Public Role
In an interview with NBC, Nanos said he believes the crime may have been targeted, though that conclusion is not certain. “We believe that it was targeted, but we are not 100% sure of that,” he said, adding that it would be wrong to assure neighbors that they are not potential targets.

Authorities have described an intensive public outreach effort, including billboards across multiple Southwestern states asking for information about Guthrie’s disappearance and reporting unconfirmed sightings in major cities. Officials have announced a combined reward of more than $1.2 million for information that helps solve the case, and the family has urged anyone with relevant details to call 1-800-CALL-FBI rather than attempt to investigate on their own.
For now, the Guthrie investigation remains an open missing-person case with no named suspect and no publicly disclosed breakthrough. The limited physical evidence places extra weight on specialized forensic testing and community tips. Whether new lab results or information from the public will shift the case remains unresolved.
