Sheriff Chris Nanos is contending with the F.B.I. director, a horde of reporters and the forces of celebrity. And then there’s the investigation itself.
The F.BI. and local law enforcement gave no details about the note, which came on the sixth day of the search for Ms. Guthrie, the mother of the “Today” host Savannah Guthrie.
The authorities confirmed that blood on Ms. Guthrie’s doorstep belonged to her. Her daughter Savannah, the “Today” anchor, released a video asking for proof that her mother is alive.
The disappearance of Nancy Guthrie, mother of the news anchor Savannah Guthrie, has reporters, neighbors and drones flooding streets and foothills in Tucson, Ariz.
The “Today” anchor withdrew from NBC’s coverage of the Winter Games in Italy as investigators acknowledged they had few answers about who may have taken her mother, Nancy Guthrie, 84, from her home.
