Pima County Sheriff Chris Nanos has issued a video update addressing Nancy Guthrie’s family after investigators released two purported ransom notes, six months after her disappearance from her Tucson home. He said the release was intended to prompt recognition of the sender’s distinctive wording or phrases and generate fresh leads, rather than indicate that the case has been resolved.

Authorities are continuing to examine evidence and information from the public in the investigation into Guthrie’s disappearance. The notes are being treated as potentially useful evidence that could help identify the person who sent them, while the sheriff reiterated investigators’ commitment to finding answers.
