Writing Quirks in Nancy Guthrie Ransom Notes May Reveal Suspect’s Identity, Investigator Says

A retired Colorado investigator has identified several distinctive linguistic patterns in ransom messages potentially connected to Nancy Guthrie’s disappearance from her Tucson, Arizona home. Lisa Miller analyzed the notes released by the Pima County Sheriff’s Department in July and concluded the same person likely authored both messages based on recurring grammatical and structural characteristics. The analysis suggests these writing habits could prove instrumental in identifying the author and generating leads in the case.

Guthrie, 84, is the mother of “Today” show co-host Savannah Guthrie. Authorities say she was abducted from her northern Tucson residence in the early morning hours of February 1 after a masked individual was captured on doorbell camera footage at her front door. Her current whereabouts remain unknown six months after her suspected kidnapping.

Miller identified comma splices—where two independent clauses are joined with a comma instead of separated by a period—as a consistent signature throughout both ransom notes. She noted additional patterns including unconventional compound formations such as “heart related” without a hyphen and “smartwatch” written as two separate words. These repeated quirks across both messages suggest a single author rather than separate individuals, Miller explained.

The investigator ruled out artificial intelligence as the source of the messages, citing a typographical error and the absence of smooth AI-generated phrasing. Instead, she suggested the distinctive language reflects the writer’s personal communication style, or idiolect, potentially shaped by regional background, religious upbringing, or literary influences. The sender’s choice of words like “perished” and phrases such as “buried in nature” may reveal deeper personal characteristics and beliefs.

Miller emphasized that making the notes public could apply psychological pressure on the perpetrator, potentially triggering behavioral mistakes or prompting someone within the suspect’s circle to recognize the writing style. She urged the public to scrutinize the messages for these specific linguistic markers and report any suspicious writing patterns encountered in personal correspondence or emails. The distinctive use of both a dollar sign and “USD” to denote ransom amounts, along with specific date and time formatting, represent additional identifying features.

Law enforcement has not officially authenticated the ransom notes, though Savannah Guthrie has expressed belief in their legitimacy and investigators have not excluded them from consideration. Rewards in the case total more than $1.2 million. The FBI encourages anyone with information to contact 1-800-CALL-FBI or call 520-88-CRIME to remain anonymous.
