Second Ransom Note in Nancy Guthrie Case

A second ransom note sent to a Tucson TV station alleges that Nancy Guthrie, mother of 'Today' host Savannah Guthrie, died shortly after her February abduction.

The new letter, similar in tone to the first, has intensified the investigation and public interest.

Savannah Guthrie made an emotional on-air plea for information, tearfully asking anyone with knowledge to come forward.

Police are still treating the case as a kidnapping and are analyzing the letters for clues.
