Savannah Guthrie's emotional plea to mom's kidnapper may signal 'new line of communication': report

Savannah Guthrie's plea Monday may signal a "new line of communication," coming as she appealed directly to her mother's kidnapper, more than 25 weeks after the 84-year-old Nancy Guthrie vanished from her Arizona home.

She made the emotional plea on Monday to her Instagram account, saying her family is "in agony" and "will never stop looking for her." on Tuesday, NBC's Erin McLaughlin reported that the new message may have been in response to a new line of communication.

"It's not clear why Savannah decided to release this message now, but it could be a response to a potential new line of communication. Experts say the language appears to be pointed at whoever committed the crime though law enforcement have not provided any public updates in the investigation recently," McLaughlin said.

In Monday's video to followers, Savannah Guthrie urged her mother's kidnappers to "Do the right thing now."

"Make the right choice. Help us find her. Tell us where to look for her," she said. "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. "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."
