Savannah Guthrie delivers 'very specific' message to mom's kidnapper 25 weeks after her abduction

Savannah Guthrie delivered a "very specific" message to her mother's kidnapper on Monday, more than 25 weeks after the 84-year-old vanished from her Arizona home.

In an emotional plea posted to her Instagram account, Savannah Guthrie appealed directly to whoever is responsible for Nancy Guthrie's kidnapping, saying that her family is "in agony" and "will never stop looking for her."

"I'm coming on today with a very specific message. It has been months since our mom was taken from us. Our family is in agony. We are in a nightmare that will not end. Nothing about our situation has changed. We have done our part, and we will never stop looking for her. We will always ache for her and feel that hole in our hearts. The world can be a cruel and unforgiving place," Savannah Guthrie said.

"And I know that you have tried to do things the right way. So I'm asking you, begging you to do the right thing now. Make the right choice. Help us find her. Tell us where to look for her. I truly believe it is never too late to do right thing. Help us bring this situation to an end. For all of us. No matter where we've been and what we've done, I believe there is always a way home. Please make the right choice."
