Savannah Guthrie begs mom's kidnappers for help

US television presenter Savannah Guthrie has made another emotional social media plea to the abductors of her mother, Nancy Guthrie, who was taken from her Arizona home in January. Guthrie begged the kidnappers to reveal her mother's location, saying her family is in agony. Investigators believe Nancy was abducted against her will. Two ransom notes were sent, one demanding millions in Bitcoin and another claiming she had died. The case remains active.
