The grammar in two ransom notes tied to the disappearance of Nancy Guthrie — the 84-year-old mother of “Today” co-host Savannah Guthrie, taken from her Tucson home on February 1, 2026 — may be the strongest lead investigators have, according to a retired Colorado investigator who has studied both letters. Lisa Miller, a former detective and onetime law enforcement executive at the Colorado Attorney General’s Office, says the writer’s repeated quirks amount to a signature that someone who knows him could recognize.
The Pima County Sheriff’s Department made the letters public on July 31, exactly five months after Nancy Guthrie vanished from her residence in northern Tucson. One demanded millions of dollars in bitcoin in exchange for her return. The other stated that she had “perished” and was “buried in nature.” More than six months on, no suspect has been publicly named and she has not been found.
One Writer, Two Letters
What jumped out at Miller first was consistency. Comma splices — full sentences joined by a comma where a period belongs — turn up again and again in both documents. Miller told Fox News Digital that seeing the same construction repeated across the two messages points, with strong probability, to a single author.
Then there are the open compounds. Words most people write as one, the author splits in half: “smartwatch” becomes two words, and so does “floodlight.” “Heart related” shows up stripped of the hyphen standard usage calls for. Those aren’t stray slips, Miller said — they’re ingrained habits, and habits leave fingerprints.
She flagged more markers of a personal style: the writer pairs a dollar sign with the abbreviation “USD” when naming the ransom figure, and formats dates and times in an idiosyncratic way.
Idiolect and What Word Choice Reveals
Underpinning all of it is a concept Miller calls central to the analysis: idiolect, the one-of-a-kind way any individual communicates, built out of a lifetime of experience. Hometown, neighborhoods lived in, slang picked up along the way — all of it leaves a trace on the page.
The vocabulary of the second letter struck her as especially telling. “Perished” instead of “died,” and the phrase “buried in nature,” read to her as products of a specific background — perhaps a religious upbringing, perhaps heavy reading. But she offered a second reading, too: softened, distancing language is a documented tendency among offenders, who commonly downplay what they did, push responsibility onto others and avoid confronting the full weight of it.
Artificial intelligence, she believes, played no part in composing the notes. There’s at least one typo, and the sentences don’t move with the smooth, uniform rhythm machine-written text tends to have. The roughness itself, she suggested, tells investigators something.
Why the Notes Went Public
The sheriff’s department said it hoped someone would recognize the sender’s “unique linguistic style,” and Miller thinks that’s a realistic goal — idiolect isn’t a switch a person can flip off, and someone in the writer’s life may already be familiar with these tics without grasping their significance. She urged people to think about whether anyone they know writes with odd phrasing or strings sentences together with commas, in letters or emails alike.
Release serves a second function rooted in offender psychology, she added. Putting the notes in front of the public squeezes whoever wrote them, and that pressure can produce what Miller termed behavioral leakage — small shifts in mood or conduct that people nearby might sense without being able to name.
The timing may have been deliberate. NewsNation’s Brian Entin said the sheriff’s office probably moved to “capitalize on that six-month moment” and shake loose fresh tips.
New details about the letters have since emerged. The first, dated February 2 and addressed to Savannah, was sent to CBS Tucson affiliate KOLD-TV and referenced a white smartwatch at the foot of Nancy Guthrie’s bed along with a damaged floodlight in the backyard. The second, dated February 6, was addressed to the Guthrie family.
Where the Investigation Stands
Nancy Guthrie was abducted from her northern Tucson home in the predawn hours of February 1, after a masked intruder turned up on her front steps 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.
DNA from a glove recovered about two miles from the house was traced to an employee of a nearby restaurant who Sheriff Chris Nanos said “has nothing to do with the case.” An earlier round of hair-evidence analysis did not point to a suspect either. The family is offering a $1 million reward; the FBI previously announced a reward of $50,000.
Human remains discovered in mid-August roughly 15 miles from her home, near West Ajo Way and South La Cholla Boulevard, are not tied to the case, the Pima County Sheriff’s Department said. No finding on the bone’s age has been released. A separate set of remains found in May, about five miles from Guthrie’s home near Craycroft and River, did turn out to be prehistoric — buried up to 1,000 years ago, according to University of Arizona anthropologist James T. Watson — and went to the Tohono O’odham Nation rather than to a homicide detective.
For now, the letters remain the case’s most scrutinized evidence. Long read as a record of what the kidnapper wanted, they may also reveal who they are — the sort of small, unmistakable detail Miller said could finally generate the phone call detectives have been waiting on.
