The FBI has launched a major trace of Bitcoin transactions in Arizona as agents race to find 84-year-old Nancy Guthrie, who vanished from her Tucson home on 31 January 2026 and has not been seen since. Investigators say the missing persons inquiry is now leaning heavily on blockchain analysis, with the bureau describing the Bitcoin work as a key part of the search.
Guthrie was reported missing more than two months ago, triggering a traditional search effort in and around Tucson. Local and federal authorities have checked known addresses, spoken to her associates and followed conventional financial trails. The shift towards a deep dive into cryptocurrency marks a notable development in a case that, until now, has produced no suspects and no clear explanation for her disappearance.
