Authorities in Arizona have released two ransom notes linked to the kidnapping of Nancy Guthrie, the 84-year-old mother of "Today" show co-host Savannah Guthrie. This move comes six months after her disappearance from her Tucson home. The notes, intended to solicit funds and identify the kidnappers, were first publicized through various news outlets prior to their official release. Both notes contain alarming details, particularly about the circumstances surrounding Guthrie's abduction, according to LA Times, BBC, and Reuters.

The first note, which investigators consider credible, was sent shortly after Guthrie's disappearance and indicated that the family must pay $4 million in bitcoin by February 5. If the payment was not received, the ransom would increase to $6 million due by February 9, with a chilling warning that failure to comply would result in her death. The note also included specific details about her personal items, lending it an air of authenticity, as detailed in reports from LA Times and Reuters.

The second note, which was sent days later, expressed remorse, claiming that the kidnappers did not realize the seriousness of Guthrie's health issues and indicated that she had died shortly after her abduction. This note stated, "Nothing you could have done could have changed the outcome," prompting the Guthrie family to continue their pleas for information about her whereabouts, according to BBC and Reuters.

Law enforcement has emphasized that the investigation remains active and has encouraged the public to assist in identifying the individual responsible for the kidnapping. They are particularly focusing on a suspect captured on doorbell camera footage tampering with equipment outside Guthrie's home before her abduction, which could be key in solving the case. The sheriff's office has called for anyone with information about the behavioral changes of individuals they might know during that timeframe to come forward, emphasizing the distinctive wording of the ransom notes, according to LA Times, BBC, and Reuters.
