Federal investigators are working to distinguish between cynical extortion attempts and potentially credible leads in the high-profile disappearance of Nancy Guthrie, as a California man has admitted to exploiting the family's tragedy with fraudulent ransom demands. The developments come as the FBI Phoenix Field Office continues to sift through a stream of correspondence regarding the missing 84-year-old, some of which falsely claimed the mother of Today presenter Savannah Guthrie had passed away.
Derrick Callella, 42, pleaded guilty on Thursday to two counts of harassment using a telecommunications device. The plea follows his admission that he targeted the family of the missing woman, sending text messages referencing cryptocurrency payments just days after her disappearance. While this federal conviction offers a narrow sense of legal resolution, the primary kidnapping investigation remains active, with authorities actively evaluating which ransom demands are legitimate and which are merely copycat scams designed to exploit a grieving family.
