Half a year after 84-year-old Nancy Guthrie, mother of prominent American news anchor Savannah Guthrie, was abducted from her Arizona residence, law enforcement has taken a new step to generate leads in the stalled investigation: releasing two authenticated ransom notes linked to the kidnapping, hoping distinctive linguistic patterns in the documents will help identify the perpetrators.
Guthrie went missing from her Tucson-area home in January this year, launching a months-long probe that has yielded little in the way of solid leads or persons of interest. The two notes, both sent to local Tucson television stations in early February, carry conflicting core claims: the first, sent February 2, demands a multi-million dollar ransom paid in Bitcoin, assures the Guthrie family that Nancy was alive but unhurt, and threatens to kill her if payment is not received by a specified deadline. The second, dated February 6, claims Guthrie died of an undiagnosed heart-related issue shortly after being taken, and states her body was buried in an unmarked natural location. Local authorities have not independently confirmed Guthrie’s death as of the release date.
Investigators are pinning new hope on forensic linguistic analysis of the notes, arguing that every individual carries a unique “language fingerprint” — called an idiolect — that can distinguish their writing from that of any other person, even when the writer attempts to hide their natural style. William Eggington, a retired Brigham Young University linguistics professor and veteran forensic consultant, broke down key clues hidden in the short documents for the BBC.
Eggington’s analysis identifies multiple revealing patterns in the first note. The writer’s consistent reliance on passive voice and structured “if-then” sentence construction suggests they have at least a high school education, and may have completed some post-secondary schooling. A notable inconsistency also appears: the writer correctly spells “received” in one sentence, but misspells it later in the text. Eggington says this inconsistency indicates either a lack of familiarity with the word’s correct spelling, or that the writer failed to closely proofread the final document before sending it.
In the second note, Eggington points out that the writer refers to Guthrie exclusively in the third person, framing her death as the result of her own unaddressed health issues rather than a consequence of the kidnapping. This, he argues, works to dehumanize Guthrie and deflect responsibility for her death from the kidnappers. The note also uses unusually formal, restricted academic phrasing that may not reflect the writer’s natural voice, indicating a likely attempt to disguise their idiolect to avoid detection.
Despite the potential for disguise, Eggington confirms one key finding: the same person wrote both notes. He cites consistent stylistic quirks, most notably the repeated habit of using a comma where a full stop is grammatically required to separate two independent clauses, as clear evidence of a single author.
Forensic teams will use these small, unique details to build a behavioral and linguistic profile of the kidnapper. Once a person of interest is identified — either through investigative work or a tip from the public — investigators can compare the suspect’s known writing samples to the ransom notes to find a match. This method has led to successful arrests in high-profile cases before: in 1995, the Unabomber Theodore Kaczynski was identified after his brother recognized his unique writing style in the manifesto Kaczynski forced major publications to publish.
Still, some criminology experts are skeptical that the notes will break the case open. Jeffrey Adler, a University of Florida professor who studies the history of American crime, points out that kidnapping is an extremely rare offense in the U.S., with most incidents involving internal family custody disputes rather than stranger abductions for ransom. With six months already passed and no solid leads to work from, Adler calls the odds of identifying the kidnapper via the notes “a stretch.”
Police confirmed they consulted extensively with the Guthrie family before agreeing to release the redacted ransom notes to the public. Hours after the release, Savannah Guthrie issued an emotional public appeal for information, saying her family is desperate for answers and urging anyone who recognizes the writing style, or has any information related to the abduction, to come forward to authorities.
