The Pima County Sheriff’s Department has released two ransom notes connected to the disappearance of Nancy Guthrie, asking the public to help identify their author. The move matters because investigators are seeking potential leads in a case that has remained unresolved for months.

The notes were made public on Friday in Tucson, Arizona, although authorities had not confirmed that they were genuine. The FBI is examining ransom demands linked to the case, with officials reportedly treating some as potentially legitimate while regarding others as fraudulent.
