Savannah Guthrie and her family are offering an additional reward of up to $1 million for any information leading to the whereabouts of their mother, Nancy Guthrie. The “Today” show co-host made the announcement on social media Tuesday.

In a new video posted to Instagram, Savannah Guthrie expressed hope that her mother will be found but also acknowledged that she “may be lost.”

“She may already be gone. She may have already gone home to the Lord that she loves and is dancing in heaven with her mom and her dad and with her beloved brother Pierce and with our daddy,” Guthrie said. “And 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.”

Nancy Guthrie has been missing since Feb. 1, when investigators believe she was abducted from her home in Tucson, Arizona.

“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 of worrying about her and fearing for her and aching for her and most of all just missing her,” Guthrie said.

The FBI is also offering a $100,000 reward, and encouraged anyone with information to contact the tip line at 1-800-CALL-FBI (1-800-225-5324).

“Someone out there knows something that can bring her home,” Savannah Guthrie said in the video. “Somebody knows, and we are begging you to please come forward now.”

She also said the family would be donating $500,000 to the National Center for Missing and Exploited Children.

“We know there are millions of families that have suffered with this kind of uncertainty,” Guthrie said, adding, “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.”
