Investigators searching for the kidnappers of 84-year-old Nancy Guthrie have uncovered a significant clue in the form of a Bitcoin wallet mentioned in the ransom notes sent to her family.

Crypto experts reviewing the communications describe the kidnappers as possible amateurs (“farkakta”), but detectives are now examining whether a $152 error early in the investigation may have inadvertently pushed the suspects further underground.

The case, which has gripped the public’s attention, involves Nancy Guthrie — mother of “Today” show host Savannah Guthrie — who disappeared in February.

Pima County Sheriff’s Department officials, including the sheriff shown addressing the media, continue to lead the high-profile investigation.

This latest development regarding the cryptocurrency element adds a new layer of complexity to an already puzzling case, as authorities work to trace any transactions or digital footprints left behind.

The family and the public continue to await answers in the disappearance of Nancy Guthrie.
