A $1 million reward is being offered for information leading to the recovery of Nancy Guthrie, who has been missing for over three weeks.

Today Show co-host Savannah Guthrie, 54, posted a heartbreaking video on Instagram pleading for help finding her 84-year-old mother, who vanished from her home on February 1.

The Guthrie family has been begging the public for weeks for help to find Nancy Guthrie, who was last seen on January 31 at her home in Tucson, Arizona.

As the fourth week of the investigation begins, Savannah put out a heartfelt plea for help to put an end to the “agony” of missing their mother.

“We know that millions of you have been praying for her return, and we feel those prayers. Please keep praying without ceasing,” she began her video.

To entice those with knowledge to come forward, Savannah said the family is offering a $1 million reward.

What we know about Nancy Guthrie’s disappearance…

• Today host Savannah Guthrie’s mom is missing, and cops believe she was abducted from her home in Tucson. They have described her home as “a crime scene”
• Just weeks before her disappearance, Nancy’s last social media post before she was taken was a sweet photo with Savannah and her grandkids
• Blood drops were seen on the home’s front step, and detectives are analyzing DNA evidence from the home
• Police confirmed her son-in-law was the last person to see her
• In a grim press conference, local and federal authorities revealed they had no videos, no suspects, and no leads
• Multiple news outlets have been sent ransom letters that contain specific details about Nancy’s home and clothing
• The letters also contained a demand for millions in Bitcoin. A first deadline passed five days after the abduction, and a second deadline on February 10 is said to contain “much more serious” conditions
• Savannah and her siblings appealed directly to their mother’s abductors in an emotional video
• In heartbreaking photos, Savannah’s sister appears shattered as she’s comforted by family and friends at her home
• Police are looking into 911 reports of a suspected trespasser lurking in a neighbor’s yard just weeks before the abduction, and investigators have been spotted probing the woods behind Nancy’s house
• Police are also probing people who know Nancy after questions arose over how she was reported missing

Prior to the million-dollar offer, the FBI offered a $202,500 reward, and an anonymous donor offered a $100,000 reward.

“We still believe in a miracle. We still believe that she can come home. We are blowing on the embers of hope,” Savannah solemnly said.

The host then changed her tune, admitting that her family knows their mother may already be dead.

“We also know that she may be lost, she may already be gone. She may already have gone home to the Lord she loves and be dancing in heaven with her mom and her dad,” she continued.

“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.”

Savannah instructed anyone with information to contact the FBI tip line and visit the FBI’s website for more information on eligibility for the reward.

“You can be anonymous if you want. Someone out there knows something that can bring her home,” she said.

“We are begging you to please come forward now.”

After announcing the increased reward, Savannah addressed the backlash her family has faced over the popularity of Nancy’s missing-person case.

Critics have voiced their concerns that Nancy’s case has received so much attention while hundreds of people go missing without fanfare.

“We know that we are not alone in our loss. We know that there are millions of families that have suffered with this uncertainty,” Savannah continued.

“We are donating $500,000 to the National Center for Missing and Exploited Children.

“We are hoping that the attention that has been given to our mom and our family would extend to all the families like ours.”
