On September 28, 2026, the Pima County Sheriff's Department announced investigators were recently made aware of a new possible ransom note in the disappearance of Nancy Guthrie, last seen January 31 and reported missing February 1. The note was a text demanding Bitcoin that a retired FBI agent tied to an April scam, and the FBI is investigating the extortion as likely run from outside the country. The same Bitcoin address appears in an April extortion email and one sent to Lauren Serpa. The discussion now centers on whether the note is genuine or a hoax, and on the limits of DNA analysis, since samples with three or more profiles cannot currently be separated scientifically.
