TODAY show co-host Savannah Guthrie and her siblings, Annie and Camron, shared a message as the search continues for their 84-year-old mother, Nancy Guthrie.

“On behalf of our family, we want to thank you all for the prayers for our beloved mom Nancy,” Savannah said.

“Momma if you’re listening, we need you to come home,” Annie said. “We miss you.”

Savannah addressed the reports of the possible ransom letter saying they are aware of them and are ready to talk.

“We are ready to talk,” Savannah said. “We need to know without a doubt that she is alive and you have her. We want to hear from you and we are ready to listen. Please reach out to us.”

Savannah said they will not rest until they are reunited with their mother.
