Possible Ransom Note Previously Investigated
Authorities previously investigated a possible new ransom note connected to Nancy Guthrie's disappearance.
On September 28, the Pima County Sheriff's Department announced that the PCSD/FBI Guthrie Task Force had recently learned of another possible ransom note related to the case.
Investigators said they were aware of social media discussions about the note and were working to establish its credibility.
However, the department issued a follow-up statement the next day, confirming the "possible ransom text message" was "not credible."
The development followed two earlier ransom notes, one demanding $4million in cryptocurrency and another claiming Guthrie had died before offering to return her body.
