TODAY Show anchor Savannah Guthrie acknowledged that her missing 84-year-old mother, Nancy, "may already be gone" while offering a reward "of up to $1 million for any information" leading to her recovery in a video shared on her Instagram account Tuesday (February 24) morning.

“I’m coming on to say it is Day 24 since our mom was taken in the dark of night from her bed, and every hour and minute and second and every long night has been agony since then. Worrying about her, and fearing for her, aching for her, and most of all just missing her," Savannah said. "Just missing her. We know that millions of you have been praying, so many people have been praying — of every faith and no faith at all — praying for her return, and we feel those prayers. Please keep praying without ceasing. We still believe. We still believe in a miracle. We still believe that she can come home. Hope begets hope, as my sisters says. We are blowing on the embers of hope.”

“We also know that she may be lost, she may already be gone. She may already have gone home to the Lord that she loves and is dancing in Heaven with her mom and her dad and with her beloved brother, Piers, and with our daddy. If this is what is to be, then we will accept it, but we need to know where she is. We need her to come home. For that reason, we are offering a family reward of up to $1 million for any information that leads us to her recovery. All of the information about this reward and the details is in the caption below. You can call the 1-800 tipline, you can be anonymous if you want. Someone out there knows something that can bring her home. Somebody knows, and we are begging you to please come forward now.”

“We also know that we are not alone in our loss. We know there are millions of families that have suffered with this kind of uncertainty, and for that reason, today, we also are donating $500,000 to the National Center for Missing and Exploited Children for their work in helping families who are coping with loss and actively looking for those who are lost. We are hoping that the attention that has been given to our mom and our family will extend to all the families like ours who are in need and need prayers and need support. So please, if you hear this message, if you’ve been waiting and you haven’t been sure, let this be your sign to please come forward, tell what you know and help us bring our beloved mom home so that we can either celebrate a glorious, miraculous homecoming or celebrate the beautiful, brave and courageous and noble life that she has lived. Please me the light in the dark. Thank you.”
