Savannah and Nancy Guthrie

US television presenter Savannah Guthrie has made another emotional plea to her mother Nancy’s kidnappers in a video she posted on social media, asking them to share her mother’s location.


"I’m asking you, begging you, to do the right thing now," the host said. "Help us find her – tell us where to look for her."


Investigators believe that Nancy Guthrie, who was last seen on 31 January, was taken against her will from her home near Tucson, Arizona, but they have not shared a possible motive or arrested a suspect.


A ransom note that was sent in the days after the 84‑year‑old was abducted claimed she had died, according to investigators.


The FBI and Pima County have spent months investigating her mysterious abduction from her Arizona home. Nancy needed daily medication and vanished sometime after she was dropped off at her home by relatives on the January evening, failing to show up the following morning at a friend's house to watch a virtual Sunday church service.


Earlier this year, authorities released images of a masked and armed suspect who covered the front door camera at Nancy Guthrie’s home before her disappearance. An initial ransom note was sent the day after she went missing and demanded millions in Bitcoin for her release.


Savannah Guthrie has said some ransom notes sent to the family were believed to be fake, and she has said her mother may no longer be alive.
