What We Know So Far: Key Evidence in the Nancy Guthrie Kidnapping Investigation

Nearly three weeks after 84-year-old Nancy Guthrie disappeared from her secluded Tucson, Arizona, home, investigators say they still lack a definitive motive or leading theory in her abduction. The case has devastated Guthrie's family—her daughter, 'Today' host Savannah Guthrie, has repeatedly pleaded on social media for anyone with information to "do the right thing" and bring her mother home.

Reward Offers

A private donor and law enforcement have each offered $100,000 for information leading to an arrest. The Pima County Sheriff's Department and the FBI have also increased their combined reward to $100,000 as authorities continue to solicit public tips.

Surveillance Footage From Doorbell Camera

On February 10, investigators released low-resolution video and still images recovered from Guthrie's Nest doorbell camera. The footage shows a man wearing a ski mask approach the front door, attempt to cover the camera with a gloved hand, then place shrubbery over the lens. The doorbell unit itself was reported missing after the disappearance; Google (which owns Nest) worked with investigators to recover stored data.

The FBI later identified the individual as the "suspect in the kidnapping of Nancy Guthrie," estimating him to be roughly 5'9"–5'10" with an average build. In the released images the suspect appears to have a holstered firearm near the center of his waist and is carrying a backpack with reflective straps. The FBI later specified the pack as a black, 25-liter Ozark Trail Hiker Pack, which is sold at Walmart; authorities said they are working with the retailer to review potential sales and leads.

Gloves, DNA, And Forensic Leads

Search teams recovered multiple gloves in the area surrounding Guthrie's home. One glove, found about two miles away, visually appeared to match the gloves seen in the doorbell footage. Investigators collected DNA from that glove and submitted it to CODIS, the national criminal DNA database that compares samples against more than 19 million offender profiles. That query returned no match.

Officials also report finding DNA on Guthrie's property that does not belong to her or anyone known to be close to her; investigators have not disclosed the exact location where that DNA was found but said they are pursuing identification. Because CODIS produced no match for the glove DNA, investigators are expected to pursue genetic genealogy — a technique that compares forensic DNA against consumer family-tree databases to identify relatives and generate investigative leads. Genetic genealogy has helped solve several high-profile cases in recent years.

Ransom Notes And False Threats

Multiple media outlets have reported receiving purported ransom notes from people claiming to hold Guthrie. Authorities have not publicly confirmed the authenticity of those messages but say they are treating them seriously. One early note published by TMZ demanded millions in Bitcoin and stated Guthrie was "OK, but scared," and reportedly included a detail about the placement of Guthrie's Apple Watch. Local stations KOLD and KGUN said they also received the same or similar communications.

Separately, the FBI charged a man for sending a bogus ransom threat connected to the case; the agency said the individual appeared to be trying to profit from the situation and that there was no evidence linking him to the disappearance.

What Investigators Are Asking For

Authorities continue to ask anyone with information—no matter how small—to come forward. Investigators have released the surveillance images to the public in hopes someone may recognize the suspect's clothing, backpack or gait, or recall suspicious activity near Guthrie's home during the relevant timeframe.
