Authorities have released two ransom notes in the disappearance of Nancy Guthrie, the mother of "Today" show co-host Savannah Guthrie, and are asking the public to help identify the writer. Nancy vanished from her Arizona home six months ago. The notes, received in the days after her disappearance, contain what investigators describe as "distinctive linguistic characteristics."
Savannah Guthrie made a new plea for information on Saturday, saying her family is desperate for someone to come forward. In an Instagram post, she said someone knows something and recognizes something, and that they are begging for help.
The release of the notes marks a new effort in the investigation, which has so far yielded no arrest. Authorities hope the writing style will be recognized.
