Six Months On, Savannah Guthrie Pleads for Mother's Return

The first ransom note, sent Feb. 2, demanded $4 million in cryptocurrency and claimed Nancy was alive but frightened. A second note, sent Feb. 6, said she had died shortly after the abduction: “She is buried in nature now. We are truly sorry.”

Investigators believe the wording and handwriting may identify the author. Doorbell camera footage shows a man who may have conducted surveillance before the abduction. The FBI has not confirmed whether both notes have been authenticated.

Authorities ask the public to report anyone who recognizes the writing style, behaved unusually around the time of the kidnapping, or showed an unusual interest–or lack of interest–in the case. Several questions remain, including how many people were involved and whether Nancy was targeted by someone she knew.
