Six months after Nancy Guthrie vanished from her Arizona home, the Pima County Sheriff’s Department has made a rare move in the hopes of breaking the case wide open. Authorities have publicly released the full text of two ransom notes linked to the disappearance of the 84-year-old mother of Today co-anchor Savannah Guthrie, including one that states that she died shortly after her abduction.Nancy Guthrie was taken from her home in Catalina Foothills, a suburb of Tucson, Arizona, on February 1. Guthrie's family reported her missing when she failed to attend a virtual Sunday church service at a friend's house the following morning. Shortly after her abduction, the FBI released a short video from Guthrie's video‑doorbell camera, showing a masked and armed individual tampering with her doorbell.The Pima County Sheriff's Department says the decision to release the ransom notes is part of a renewed effort to identify the person behind them, hoping the writer's distinctive language and phrasing could trigger someone's memory.More on this in our story.Nancy Guthrie's ransom notes might bring fresh challenges (and leads)While the ransom notes claim that Nancy Guthrie died shortly after she was taken, the investigation remains active. The Pima County Sheriff's Office does not consider the note as verified proof of her death.The authorities are determined to catch the perpetrators and have asked the public to help identify the writer whose "distinct linguistic characteristics may be recognisable".In a statement to news outlets, the sheriff's office urged the public to help in the Guthrie case:"A friend, family member, coworker, classmate, or acquaintance may recognise these patterns of expression and possess information that could help identify the individual responsible.''The release of the previously undisclosed ransom note has added another layer of complexity to the Nancy Guthrie investigation. While the message claims that she died shortly after the alleged abduction, authorities have not been able to verify its contents, leaving investigators to determine whether it contains genuine information or is another deliberate attempt to mislead the case. Officials are now closely examining the note's wording and other forensic evidence in hopes of identifying its author and uncovering fresh leads.The disturbing ransom notes left in the Nancy Guthrie caseAfter months of investigation, the Pima County Sheriff’s Department has released the ransom notes sent to Nancy Guthrie's daughter and family in hopes of catching the perpetrators.The first note, sent on February 2 ( a day after she was abducted from her house), revealed the details of Guthrie's abduction and demanded payment in cryptocurrency with clear deadlines. The ransom note, addressed to Savannah Guthrie, revealed that her mother had been abducted for ransom. The note assured the family that while Guthrie is safe, she is scared and will be held for a maximum of seven days. The abductors also assured Savannah and the family that their mother will be released unharmed after the payment.The Nancy Guthrie ransom note further described the kidnappers' demands. The Guthrie family was instructed to 'send bitcoin in the amount of $4 million USD before 5 PM on Thursday the 5th.' The note also revealed that failure to pay would increase the amount to 6 million USD, to be paid by '5 PM on Monday the 9th.'The note concluded with a Bitcoin address, revealing that Nancy Guthrie will be released 12 hours after the deposit. The note also warned that if the family failed to make the payment til the last deadline, Guthrie would be killed. The kidnappers also advised the family to complete the task as soon as possible, for the betterment of their mother and not involve law enforcement, as they 'will not be able to help you'.While the family and the Pima County Sheriff’s Department were likely fishing for clues in the first note, they received tragic news in a second ransom note in the Nancy Guthrie case. The second note was short and claimed that the abductors failed to grasp the seriousness of Guthrie's physical condition, who died shortly after her abduction, likely from a heat-related issue. The note even apologized for Guthrie's death, claiming that the abductors never intended to hurt her.The second ransom note concluded by revealing that Guthrie is 'buried in nature now,' and the final note is meant to give her family peace and closure.By making the messages public for the first time, officials hope fresh scrutiny will generate new leads in the Nancy Guthrie case that has remained one of the year's most closely watched disappearances.For the latest scoops on your favorite TV shows and movies, follow SoapCentral.
