Arizona Gun Store Owner Says FBI Presented List of Names While Tracking Firearm Purchases Potentially Connected To Nancy Guthrie Investigation

·

·

You’ll get a clear, immediate picture: an Arizona gun shop owner says an FBI agent handed him a list of roughly two dozen names and photos and asked him to check whether any of those people bought guns from the store in the past year. That action shows investigators are using local sales records as one thread in the broader effort to trace potential links to Nancy Guthrie’s disappearance.

The detail from the gun shop points to a methodical push by authorities to match surveillance evidence and item traces with purchase histories, and the article breaks down how that process works and what it might mean for the investigation. Expect a close look at the FBI’s record-checking practices, the items and footage under scrutiny, and what investigative steps remain as the search continues.

FBI’s Approach Tracking Firearm Purchases in the Nancy Guthrie Investigation

The FBI checked local firearm sales records and visited shops to match names and photos against recent purchases. Agents asked owners to search their sales systems for specific last names and images tied to the probe.

How the FBI Engaged Gun Store Owners

An FBI agent visited Armor Bearer Arms in Tucson and asked co-owner Phillip Martin to check the shop’s sales records for several names and photos. Martin typed last names into the store’s point-of-sale system to see if any matched recent customers, and he said nothing came up for the list he reviewed.

The interaction was direct and on-site: agents brought printed photos and a multi-page list to the counter and asked staff to search by last name. The visit fit a pattern of investigators canvassing local retailers when trying to trace purchases tied to items seen in surveillance footage.

Martin said he initially hesitated but agreed to help out of sympathy for Nancy Guthrie’s family. Law enforcement sources indicate the FBI planned to visit other area gun shops to repeat similar checks.

Details of the List Presented to Arizona Gun Shop

The list the agent carried reportedly spanned three pages and contained roughly 18 to 24 names with accompanying photographs. The names included uncommon surnames, which Martin said he did not recognize among regular customers at his Arizona gun store.

Agents asked staff to enter last names into their sales database, which typically displays first name, phone number, and address when a match exists. The absence of matches at Armor Bearer Arms does not rule out purchases elsewhere; investigators are checking multiple retailers and vendor records.

Printed photos helped staff visually confirm whether a listed individual appeared as a buyer, supplementing database searches. That visual element matters when aliases or minor spelling differences could obscure automated matches.

Role of Firearm Records in Identifying Suspects

Firearm purchase records can link a buyer to a weapon or related accessory, making retail logs valuable when a suspect’s gear—like a backpack or holster—appears in surveillance. Agents used store sales checks to narrow which names merit deeper follow-up through federal traces or store-supplied receipts.

Retail records often show buyer details and transaction dates, enabling investigators to establish timelines and cross-check surveillance timestamps. When initial checks at one store returned no hits, the FBI typically expands to other local shops and national retailers to trace potential purchases.

Law enforcement sources say these checks complement other evidence such as doorbell footage and DNA, forming a multi-pronged effort to identify suspects rather than relying on sales records alone.

Ongoing Search for Nancy Guthrie: Evidence and Investigation Updates

Investigators have recovered physical items, reviewed multiple video sources, and interviewed witnesses while coordinating a broad multiagency effort. DNA testing, surveillance footage and descriptions of items found near the Guthrie home have driven the active lines of inquiry.

DNA Evidence and Forensic Leads

Authorities recovered a black glove near Nancy Guthrie’s Tucson-area home that is undergoing DNA analysis. The Pima County Sheriff’s Office and FBI are comparing profiles to criminal databases; officials have said results could link an unknown individual to the scene or eliminate suspects already cleared by investigators.

Teams have also cataloged about 16 items found in the search area, including clothing fibers and disposables, to build a timeline. Forensic examiners are using touch DNA, trace evidence, and cross-referencing the glove profile with investigative leads developed from gun-purchase checks and local interviews.

Surveillance Videos: Nest and Doorbell Footage

Doorbell and Nest camera clips show a masked, armed person on the Guthrie porch the morning she disappeared. The imagery prompted the FBI to publicly release frames to solicit tips and has been central to identifying gait, clothing, and movements consistent with an approach to the front door camera.

Investigators continue enhancing and analyzing the footage for timestamps, reflected light, and other clues. Analysts compare the porch footage with neighborhood cameras and cell-tower data to refine time windows and possible travel routes away from the property.

Suspect Description and Key Items: Backpack and Holster

Witnesses and photo enhancements describe a person wearing dark clothing, a mask, and carrying what appears to be a backpack. Authorities recovered an Ozark Trail–style backpack among items near the home; forensic teams are testing it for DNA and trace material that could tie a person to the scene.

Reports also note a possible firearm holster and discussions about nearby gun-purchase records as leads investigators are pursuing. The presence of a holster and a backpack shaped several interview lines with gun shops and sellers while officers check sales histories for matches to the timeframe.

Cooperation Between Agencies and Community Impact

The Pima County Sheriff’s Office, led publicly by Sheriff Chris Nanos, is working with the FBI and other federal, state, and local partners on the multiagency search. Dozens of agents have canvassed desert areas and neighborhoods, sharing evidence and briefing Savannah Guthrie and family members, whom the sheriff has publicly cleared as not under suspicion.

Community response has included tip submissions, volunteer searches, and heightened local concern after the widely broadcast footage. Law enforcement has asked for restraint from armchair speculation, noting unvetted theories can hamper investigation timelines and misdirect resources while forensic testing continues.
