The FBI has determined that all three alleged ransom notes linked to the disappearance of Nancy Guthrie, the 84-year-old mother of Today show co-host Savannah Guthrie, were fake. The finding challenges one of the central theories surrounding the Arizona case, although investigators have not said whether it changes their belief that Guthrie was abducted.
The findings came after federal investigators examined three separate messages connected to the case.
