“Today” show host Savannah Guthrie on Saturday said on social media that her family was “desperate” and “begging for help” in the disappearance of her mother, a day after authorities released two ransom notes including one saying that she had died.

Authorities released an early note in the investigation into the disappearance of 84-year-old Nancy Guthrie, hoping that someone will recognize the writing style. A second note said Guthrie died shortly after she was kidnapped and “is buried in nature now.” Both notes initially were sent to a Tucson television station days after Guthrie went missing from her home outside Tucson on Feb. 1.
