A former FBI agent in the United States has claimed the kidnapping of Nancy Guthrie in Tucson, Arizona is now being viewed as a '$6 million bitcoin wrench attack by proxy', after a major crypto‑security firm flagged the case in what she calls the biggest public break so far. Retired agent Jennifer Coffindaffer, a regular commentator on high‑profile investigations, shared the Nancy Guthrie update on Saturday 13 June on X, saying a fresh assessment by blockchain security company CertiK had reshaped how the abduction is being read by investigators and online sleuths.
Guthrie, 84, is the mother of Today co‑anchor Savannah Guthrie and has been missing for more than four months. She was last seen at her home in the Catalina Foothills area near Tucson on 31 January, according to US reports, and was reported missing by family the following day. Since then, the Pima County Sheriff's Department and the FBI have been processing DNA evidence, following up tips and reviewing ransom letters that demanded bitcoin, while Savannah has publicly offered a $1 million reward for her mother's return.
