The desperate search for Savannah Guthrie’s missing mother has taken another shocking turn, with the FBI reportedly concluding that three ransom messages linked to her disappearance were fake.

Nancy Guthrie, 84, has not been seen since her family dropped her off at her Tucson, Arizona, home on the evening of January 31 following dinner and a family game night.

Investigators initially feared several disturbing messages may have come from the people responsible for taking her. But according to two law enforcement sources, none of the notes are now believed to be genuine.

“None of the ransom notes are believed to be genuine,” an FBI official told Reuters on the condition of anonymity.

A second source familiar with the investigation reportedly confirmed the FBI’s conclusion.

The revelation is a devastating setback for Nancy’s family, who had responded to at least two of the messages in the hope that she was still alive and could be brought home safely.

One of the alleged kidnappers initially demanded a single Bitcoin in exchange for Nancy’s return.

Authorities were reportedly prepared to cooperate and deposited a small amount of cryptocurrency into an account listed in the message.

But the money was never claimed.

That raised major red flags for investigators, who ultimately determined that the first two ransom notes had likely been sent by someone with no connection to Nancy’s disappearance.

A third note surfaced more recently from a person claiming to know the identities of the kidnappers. The FBI has also dismissed that message as fake, although officials have not revealed exactly how they reached that conclusion.

The ransom messages initially appeared credible because they reportedly included details that had not been widely released to the public.

One email, which was sent to two Tucson television stations and TMZ, described what Nancy had been wearing when she vanished and mentioned a damaged floodlight in her backyard.

The note claimed Nancy was alive and “safe but scared” and promised she would be released if the family paid the ransom by February 5.

A second message allegedly increased the demand to $6 million in Bitcoin and set a final deadline of February 9.

It ended with the chilling warning “or else.”

Investigators have never publicly explained exactly how Nancy was removed from the property. However, Savannah later revealed that the home’s back door was already propped open when her sister, Annie, arrived and realized their mother was missing.

As the search dragged on, Savannah appeared in an emotional video with her siblings, Camron and Annie, pleading for anyone with information to come forward.

The Today anchor later admitted the family had received several suspicious messages and struggled to determine which, if any, were real.

“There are a lot of different notes, I think, that came, and I think most of them — it’s my understanding — are not real, and I didn’t see them,” Savannah told Hoda Kotb in March.

She also condemned anyone cruel enough to target a grieving family with a hoax.

“A person that would send a fake ransom note really has to look deeply at themselves, to a family in pain,” she said.

At the time, Savannah still believed the first two notes may have been legitimate.

“But I believe the two notes that we received, that we responded to, I tend to believe those are real,” she said.

Now, with all three notes reportedly ruled out, investigators appear to have lost one of the biggest potential leads in the case.

Nancy remains missing, her family remains desperate for answers, and the mystery surrounding what happened inside her Tucson home has only grown darker.
