Savannah Guthrie posted a new message on Instagram about her mother’s abduction almost six months ago, pleading with those who may have information to come forward.

“It has been months since our mom was taken from us,” Guthrie said. “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.”

She added, “The world can be a cruel and unforgiving place, 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 the 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.”

Nancy Guthrie disappeared from her home the night of Jan. 31, but there have been frustratingly few leads. The FBI released doorcam video that showed a masked individual at Nancy Guthrie’s front door early in the morning of Feb. 1.
