Amid the tragic and harrowing case, one specific detail has cast a long, chilling shadow over the search…Days after Nancy Guthrie, the 84-year-old mother of “Today” show cohost Savannah Guthrie, vanished from her Arizona home, authorities say they still have no suspects, no persons of interest, and no proof of life. But what they do have is evidence they cannot afford to ignore.During a press conference on Thursday, February 5, 2026, Pima County Sheriff Chris Nanos confirmed the investigation had entered its fifth day.

He stressed that despite the alarming discoveries, officials still believe Nancy could be alive. Chris emphasized, “We want her home.”However, the sheriff also underscored a frightening medical concern: Nancy requires daily medication, and investigators have no indication she’s had access to it since she disappeared. To make matters even worse, he added that being without it for several days “could, in itself, prove fatal.”Outside of the medication saga, Chris confirmed the most unsettling detail yet. Blood found on the porch outside the home was tested and confirmed to belong to Nancy. On the matter, Chris divulged:Authorities now believe Nancy’s disappearance occurred sometime between Saturday night, January 31, and late Sunday morning, February 1. That window has become the backbone of the investigation.Nancy had dinner with family Saturday evening and was brought back to her desert home just north of Tucson between 9:30 and 9:45 p.m. Officials say investigators are even considering an earlier start time of 8:30 or 9 p.m. for extra measure.
