A mysterious person who repeatedly contacted TMZ claiming to know who was responsible for Nancy Guthrie’s disappearance has become an intriguing part of the investigation, as authorities continue searching for information that could help explain what happened to the 84-year-old Arizona woman.

Guthrie disappeared from her home in Tucson’s Catalina Foothills on February 1, 2026. More than seven months later, investigators have made no arrests and have not publicly identified a suspect in the case. Authorities continue to treat the disappearance as a kidnapping-for-ransom investigation, while the FBI and Pima County Sheriff’s Department remain involved.

According to TMZ executive producer Harvey Levin, the media organization received an email from an individual claiming to know the people responsible for Guthrie’s disappearance. The person allegedly claimed to know both where Guthrie was and where the people responsible could be found.

The sender reportedly demanded one Bitcoin in exchange for the information. The person also made comments suggesting that time was no longer critical, according to Levin’s account.

The communications became particularly interesting because TMZ had already received what investigators believed could be a genuine ransom note. Levin said TMZ worked with the FBI for weeks, including allowing investigators to examine technical information connected with the emails, in an effort to determine who was behind the communications. Investigators were reportedly unable to identify the sender.

In a June 2026 discussion, Levin said the person continued sending messages and appeared to claim inside knowledge about the case. Investigators, according to reporting at the time, were examining whether the individual might eventually be identified and whether the information being offered had any connection to the disappearance.

However, there is an important distinction between the claims made by the anonymous sender and facts established by investigators. Authorities have not publicly confirmed that the person actually knew the kidnappers or had direct knowledge of Guthrie’s whereabouts.

The FBI has also acknowledged that investigators received multiple purported ransom demands during the case. Some were determined to be extortion attempts without legitimate information, while others remained under investigation. The agency has said the investigation continues to be handled as a kidnapping-for-ransom case, with Pima County authorities leading the investigation and the FBI providing ᴀssistance.

The mystery surrounding the communications comes as investigators continue examining a large amount of evidence collected since Guthrie disappeared. Pima County Sheriff Chris Nanos previously said detectives and federal investigators were reviewing tens of thousands of pieces of video footage, along with cellular data and other evidence.

Investigators have also released images from a doorbell camera showing a masked individual believed to be connected to Guthrie’s disappearance. Authorities have appealed to anyone who recognizes the person or knows something about the case to come forward.

Another unusual development involves two notes that authorities have publicly released. Investigators said the notes appeared to share distinctive linguistic characteristics and could potentially have been written by the same person. Officials have asked people who might recognize the writing style—including friends, relatives, coworkers or acquaintances—to contact investigators. At the same time, authorities have not publicly established that every purported note or message received during the investigation is authentic.

The authenticity of the ransom-related communications has itself become a subject of disagreement. Some outside experts have questioned whether the language and behavior reflected in the messages are consistent with a genuine kidnapping. The FBI, however, has said some ransom demands may potentially be legitimate and remain under investigation. That means the public claims surrounding the emails should not be treated as proof that the sender was connected to Guthrie’s disappearance.

The mystery tipster is therefore one of several unresolved threads in a case that has generated a large volume of information, tips and speculation. Investigators have repeatedly encouraged people with genuine knowledge to contact law enforcement rather than attempting to negotiate independently with an anonymous source.

For Guthrie’s family, the central question remains unanswered: where is Nancy Guthrie, and what happened to her after she disappeared from her Tucson home?

Her daughter, NBC News journalist Savannah Guthrie, has continued to publicly appeal for information and has urged anyone who knows something to come forward. Investigators have also emphasized that even a seemingly minor piece of information could become important when combined with evidence already collected.

As of September 2026, no suspect has been publicly charged in connection with Nancy Guthrie’s disappearance. The anonymous person who contacted TMZ has not been publicly identified, and authorities have not confirmed that the individual possesses reliable information about the case.

The investigation remains active, with detectives continuing to examine video, digital evidence, forensic material, tips and communications received since Guthrie vanished. Whether the mysterious emails ultimately lead investigators to a meaningful breakthrough remains unknown, but they represent another unresolved thread in one of Arizona’s most closely watched missing-person investigations.
