The FBI is investigating ransom notes related to the disappearance of Nancy Guthrie. Some of these notes have been deemed extortion attempts and have been discounted by the agency.

However, the FBI is still evaluating other notes that may be legitimate. The total number of ransom notes received is not specified, except that it is described as "several".

Further details about the investigation and the ransom notes are available from the FBI, although the agency has not released additional information at this time.
