The clock is ticking. In Thursday's press conference, FBI special agent in charge Heith Janke confirmed a harrowing detail amid the search for Nancy Guthrie. We've heard reports of ransom notes being sent to media outlets. The authorities are taking the reported notes very seriously and are heavily investigating every tip - which already led to the arrest of person connected with an "imposter" ransom note. Savannah and her siblings have also expressed a desire to hear from whoever may have their mother, noting they're "ready to talk" but need proof of life, as well.
