In a video clip on social media, NBC host Savannah Guthrie and her siblings directly address the potential kidnappers.
"We beg you to give our mother back to us. We will pay," Guthrie says.
Nancy Guthrie was reported missing from her Arizona home a week ago. According to police sources, investigators have found evidence suggesting she was abducted.
American media outlets have received several ransom demands – several million dollars in bitcoin – from people claiming to be involved. However, police have not commented on the credibility of the demands.
