The two ransom letters tied to the suspected kidnapping of Nancy Guthrie — the 84-year-old mother of “Today” co-host Savannah Guthrie, taken from her Tucson home on February 1, 2026 — are riddled with the same repeated grammatical tics, and a retired Colorado investigator believes those quirks may be the thread that finally leads police to the person who wrote them.
Lisa Miller, a retired detective who previously served as a law enforcement executive at the Colorado Attorney General’s Office, went through both letters after the Pima County Sheriff’s Department made them public on July 31 — the six-month mark since the 84-year-old disappeared from her residence in Catalina Foothills, north of Tucson. The first note demanded $4 million in bitcoin by 5 p.m. on February 5, rising to $6 million by 5 p.m. on February 9. The second told the family: “She perished shortly after she was taken. We believe it was heart related.” It said she was “buried in nature now.” Nobody has been publicly identified as a suspect, and Nancy Guthrie still has not been found.
New details have since emerged about how the messages reached the family. The first was delivered to CBS Tucson affiliate KOLD-TV on February 2 and was addressed to Savannah. The second, written to the Guthrie family, arrived at the same station on February 6. The sheriff’s office said the letters “provide valuable insight into the mindset, motives and the evolution of their tone over time.”
NewsNation’s Brian Entin said the decision to release the notes was likely engineered to “capitalize on that six-month moment” and shake loose fresh tips.
A Consistent Hand Across Both Notes
What jumped out at Miller first was the sameness of the voice. Comma splices — full sentences stitched together with commas where a period belongs — turn up again and again in both documents.
That repetition, Miller told Fox News Digital, points with strong probability toward one author behind both messages.
She also flagged a habit of pulling apart open compounds — terms most people write as one word but that the letter writer splits in two. “Smartwatch” shows up as two words. “Floodlight” does the same. And “heart related” is written without the hyphen standard usage calls for. None of it reads as accidental to Miller. These are ingrained habits, she said, and habits leave fingerprints.
Two more oddities caught her attention: the writer pairs a dollar sign with the abbreviation “USD” when naming the ransom figure, and formats dates and times in an idiosyncratic way. Both, she said, are additional markers of a personal style.
Idiolect and the Psychology of the Writer
Underpinning the whole analysis is a concept Miller calls idiolect — the one-of-a-kind way an individual communicates, shaped by everything they have lived through. Hometown, the neighborhoods a person has passed through, the slang they picked up along the way: all of it bleeds into how they write.
The vocabulary of the second letter struck her as especially telling. Choosing “perished” over “died,” and describing a body as “buried in nature,” suggests someone whose language was molded by a specific background — religious upbringing, perhaps, or heavy reading. But Miller floated a second reading, too: those cushioned, distancing words may reflect a mental habit common to offenders, who routinely downplay what they did, push responsibility onto other people, and avoid confronting the true weight of it.
Artificial intelligence, she said, almost certainly did not write these. There is at least one typo, and the sentences move in a jagged, uneven rhythm rather than the smooth cadence machine-generated text tends to produce. The rough edges, in her view, carry information of their own.
Crowdsourcing a Clue
The sheriff’s department has said it hopes “a friend, family member, coworker, classmate, or acquaintance may recognize these patterns of expression,” and Miller thinks that is a realistic ask. Idiolect isn’t something a person can simply turn off, and someone who knows the writer may already be familiar with these patterns without grasping that they are sitting on a piece of the puzzle.
She encouraged people to think about whether anyone they know writes with strange phrasing or strings sentences together with commas — in emails, in letters, anywhere. Those recognizable tendencies, she said, could be useful to investigators.
There is a second reason to put the notes in front of the public, one that has less to do with grammar than with nerves. Making the letters public squeezes whoever wrote them, Miller said, and that pressure can generate what she described as behavioral leakage — small shifts in mood or conduct that friends and relatives may pick up on without being able to explain what feels off.
What Investigators Have So Far
The abduction happened in the predawn hours of February 1, after a masked intruder turned up on the front steps of Nancy Guthrie’s Catalina Foothills home and was recorded by her doorbell camera. The FBI released that footage, and DNA collected at the scene went to the FBI Laboratory for testing.
Forensic work is continuing on other fronts. Investigators are now examining DNA taken from a glove recovered near the scene. An earlier round of hair-evidence testing did not produce a suspect.
Human remains discovered in mid-August roughly 15 miles from the Guthrie home, near West Ajo Way and South La Cholla Boulevard, are not thought to be tied to the case. Officials said there is “no indication” of any connection, adding that the remains had likely been in place for some time and that a preliminary review indicated the bone is probably prehistoric.
The financial stakes for information have climbed sharply. The FBI is offering $100,000. The family is now offering a $1 million reward for Nancy’s recovery.
Meanwhile, internet sleuths have tried to attach the figure known as “Porch Guy” to Alex James Barnett, 33, charged with first-degree murder, armed robbery and aggravated assault in the August 19 killing of Carlos Ramirez, a 23-year-old police recruit days from graduating. Barnett was arrested on the night of August 24, after a three-hour SWAT standoff on Tucson’s east side. Authorities have drawn no link between him and the Guthrie case or the doorbell footage.
For Miller, the takeaway is that the letters may do more than spell out a kidnapper’s demands. The grammatical fingerprints running through both pages could also reveal who they are — and, she said, they are precisely the sort of detail that might finally trigger the phone call detectives have been waiting on.
