Authorities in Arizona released two ransom letters on Friday allegedly written by the abductors of Nancy Guthrie, the 84-year-old mother of NBC "Today" co-host Savannah Guthrie, six months after she vanished from her home in Pima County on the night of Jan. 31.
The first letter, dated Feb. 2, demanded $4 million in bitcoin within three days for her safe return and threatened to kill her if the family did not comply. A second letter, sent to media outlets on Feb. 6, stated that Nancy Guthrie had died shortly after her abduction, allegedly from a cardiac issue, and was "buried in nature."
The Pima County Sheriff's Office said investigators are continuing to analyze the letters to identify their author and urged the public to come forward with any information. Savannah Guthrie recently appealed on social media for the abductors to reveal where her mother is buried.
