Overview
- Jennifer Coffindaffer, a retired FBI agent, posted a CertiK screenshot on Saturday, June 13, saying the firm described Nancy Guthrie’s disappearance as a “wrench attack by proxy” tied to a $6 million bitcoin demand.
- Authorities have not confirmed CertiK’s assessment, no arrests have been made, and the Pima County Sheriff’s Department and the FBI continue to process DNA evidence and follow tips.
- Earlier in the case investigators received ransom letters demanding bitcoin and Savannah Guthrie publicly offered a $1 million reward as officials worked the disappearance reported on February 1.
- A wrench attack by proxy means criminals use threats, coercion, or a hostage to force someone to surrender access to cryptocurrency rather than hacking a wallet online.
- Tracing and attributing crypto extortion can be technically complex, so if CertiK’s claim holds investigators may shift focus to financial-forensics work and network tracing that could alter investigative leads and resource needs.
