Investigators Find Unknown DNA at Nancy Guthrie’s Tucson Home Amid Search

Investigators searching for missing Arizona woman Nancy Guthrie announced they had recovered DNA at her Tucson-area home that does not belong to the 84-year-old or anyone in her close circle, a development that deepened the mystery even as it offered a new forensic lead newsnationnow +1. Guthrie, the mother of “Today” co-host Savannah Guthrie, had been missing for nearly two weeks as of Friday.

Authorities said the unidentified DNA was collected from Guthrie’s property, where blood found earlier on the front porch had already been matched to her people +1. She was last seen on the night of Jan. 31, when an Uber dropped her at home after a family dinner; by early Feb. 1, her doorbell camera and heart-monitoring app had gone offline, and relatives reported her missing around midday mb.

What the DNA and Video Evidence Reveal — and Don’t

The Pima County Sheriff’s Department said “DNA other than Nancy Guthrie’s and those in close contact to her has been collected from the property” and that investigators are working to identify whose it is people. Samples have been compared to family members, caregivers and others known to frequent the home, with no match reported so far, suggesting a potentially unknown person at the scene.

The new DNA finding joined a growing body of physical evidence. Investigators have recovered several items, including gloves found up to about two miles from Guthrie’s home, which are being tested for forensic traces people +1. Meanwhile, back-end recovery of Guthrie’s Nest doorbell footage yielded images of a masked, apparently armed person on her porch in the early hours of Feb. 1, tampering with the camera. The FBI described the person as a man roughly 5'9" to 5'10" with an average build, carrying a black 25-liter Ozark Trail backpack, and increased its reward for information to $100,000 on Feb. 12 wionews +1.

A High-Profile Search Marked by Ransom Claims and Scrutiny

The high-profile case has unfolded amid intense public attention and a blizzard of tips — more than 10,000 by some counts — as federal and local agencies crisscrossed southern Arizona and executed at least one search warrant at a property in Rio Rico, where a man was briefly detained and later released without charges wionews +1. Sheriff Chris Nanos said no one, including family members, had been ruled out, but stressed that investigators believed Guthrie was “still out there” newsnationnow.

Multiple purported ransom messages demanding cash or Bitcoin have been sent to Guthrie’s family and media outlets, prompting the FBI to examine both their authenticity and related cryptocurrency activity wionews. One man has already been charged over an alleged fake ransom text, highlighting how hoaxes can siphon resources from the core search foxnews. At the same time, Nanos has faced criticism over decisions about where DNA is tested and over a Reuters report alleging the FBI was blocked from some evidence — a claim he has strongly denied, saying, “We’re going to find this guy… we won’t quit” nytimes +1.

The Bigger Picture

The emergence of unknown DNA inside Guthrie’s home, combined with the unsettling images of a masked figure on her porch, underscored that investigators are now heavily reliant on forensics and public tips rather than a clear suspect or verified ransom communication. With a six-figure reward on the table, a national audience watching, and thousands of leads to triage, the case has become a test of how modern policing blends digital surveillance, DNA science and crowd-sourced information — and how quickly those tools can bring answers for a family still pleading, in Savannah Guthrie’s words, “Bring her home” wionews.
