"We are begging for help. We are desperate. We need someone to come forward. Someone knows something. Someone suspects something. Someone recognizes the writing in the ransom demand notes," the 'Today' show co-anchor wrote in part on Instagram Saturday.

Savannah Guthrie shared another emotional message Saturday morning, marking six months since her mother, Nancy Guthrie, went missing, as authorities continue to search for answers in the case.

Her post came after the Pima County Sheriff’s Department released two ransom notes allegedly sent by her kidnappers shortly after Nancy’s disappearance in hopes of generating new leads.

Guthrie shared a photo of her mother, 84, alongside a lengthy caption, writing, “Six months ago, someone took her out of her bed in the dead of night. We have lived every moment, every breath, and every heartbeat in agony and despair ever since. Every day, we wake up and try to be strong and go on — because that’s what our joyful and resilient mom taught us to do.”

“But make no mistake — our hearts are in ruins. Cam and Kristine, Annie and Tommy, Mike and me — we spend every waking moment thinking of her, longing for her, looking for her,” she continued. “There is a hole inside us that can never be filled. There is an ache that cannot be softened. And there is a determination in us that cannot be quenched — to find out what happened to her, so that we can give her the dignity of a proper goodbye — a celebration of her remarkable life that she so deserves.”
