"Today" host Savannah Guthrie shared a touching Mother's Day tribute to her missing mom, Nancy Guthrie, vowing that she will "never stop looking" for the 84-year-old—more than three months after she vanished from her Arizona home.

Savannah, 54, who announced on Monday that she will be hosting a new NBC program—a Wordle game show—took to Instagram on May 10 to post a series of videos and photos of Nancy, several of which appear to have been taken in and around the Tucson-area property where she raised all three of her children.

The photos and videos capture Nancy spending time with her family, including children Savannah, Annie, and Cameron, as well as her grandchildren.

"Mother, daughter, sister, Nonie—we miss you with every breath. We will never stop looking for you. We will never be at peace until we find you," Savannah wrote in the caption of the video.

The "Today" host went on to issue a fresh plea to members of the public, asking for their help in finding her mother, who vanished from her house in the Catalina Foothills on Feb. 1, and calling attention to the fact that the $1 million her family promised to anyone who provides information about Nancy's whereabouts is still available.

"We need help. Someone knows something that can make the difference," she continued. "Call 1800CALLFBI. You can be anonymous and the reward remains available.

"Please keep praying. Bring her home."

Photos and videos included in the post capture Nancy over a period of many years, including some taken when Savannah and her siblings were still children, while others show the grandmother building gingerbread houses with her grandkids or spending time with her own siblings.

One day later, Savannah shared some much more positive news about her own career—revealing on the May 11 episode of "Today" that she has signed on to a major new NBC project, alongside "The Tonight Show" host Jimmy Fallon: a game show inspired by The New York Times' popular Wordle game.

"This is very exciting, I have a big announcement to make," Fallon, who will serve as an executive producer on the project, shared. "We've been developing Wordle as a game show for the past two-and-a-half years with The New York Times, and it's official—we are making Wordle Game Show with our host, Savannah Guthrie!"

Savannah chimed in to share her excitement at finally being able to reveal the project, stating: "We've been holding this secret between us for a long time now. And we're going to make Wordle a game show."

The news was shared just days after the Tucson Police Department confirmed that human remains had been uncovered on May 7, around 7 miles away from Nancy's Arizona dwelling, while insisting that the bone that was found had no connection to her case.

A spokesperson for the local police department said that further analysis revealed the bone's discovery was part of a “prehistoric anthropological investigation," adding that it was "not criminal in nature."

However, the statement marks one of the first times that the authorities have shared any kind of update in the case in several weeks—having long since ceased any daily media briefings about the investigation.

Many questions have been raised about the handling of the case and the lack of progress that appears to have been made in tracking down Nancy's alleged abductors, even after video footage taken by a security camera at her home was released to the public.

Savannah sparked fresh concerns about the state of the investigation on May 6, when she abruptly exited the "Today" show around 30 minutes before her two-hour flagship segment was due to end.

Her co-star, Craig Melvin, attempted to reassure viewers about her absence, saying: "Savannah had to leave a little early. She’ll be right back tomorrow, though."

No other information about her sudden departure was shared—and she returned to the show on May 7, when Page Six reported that her exit had "nothing" to do with Nancy's case, but was related to an urgent "appointment" that she needed to attend.

In mid-April, it was revealed that DNA evidence uncovered at Nancy's home had finally been transferred to an FBI laboratory, having initially been sent to a private lab in Florida.

On April 16, more than two months Nancy went missing, FBI sources told NewsNation and ABC News that its official laboratory has received a DNA sample, noting that the evidence was not new, but rather had been extracted from a variety of materials collected at the property in early February.

"There is no new DNA evidence in the Nancy Guthrie case. The FBI requested this material over two months ago," an FBI official told ABC News.

"The Pima County Sheriff's Office sent it to a private lab in Florida. Eleven weeks later, that lab has now transferred an original hair sample to the FBI Laboratory for testing. We remain fully committed to this investigation."

According to the outlet, the FBI planned to use "new technology to conduct advanced analysis on the DNA sample" in order to see whether it might provide information about Nancy's alleged kidnappers.

Pima County Sheriff Chris Nanos—who has come under heavy criticism over his handling of the case—previously stated in March that authorities had collected a number of DNA samples from Nancy's home, but that authorities were struggling to extract individual profiles from that evidence.

"It’s a challenge because we know we have DNA, but now we have to deal with that mixture and how we’re going to separate it," he said.

Sheriff Nanos has admitted that authorities were struggling to separate out cross-contaminated DNA discovered inside Nancy's home, revealing that investigators had run into some "challenges" in their examination of the evidence.

"We listen to our lab, and our lab tells us that there’s challenges with it, and we understand those challenges," he told NBC News at the end of February.

"But our lab also knows that the technology is moving so fast and in such a frenzy that they think some of this stuff will resolve itself just in a matter of weeks, months or maybe a year, to allow them to do better with, say, a mixture of that kind of thing."

At the time, Nanos also noted that previous DNA samples that had been submitted to the Combined DNA Index System (CODIS), a database used by the FBI to track convicted criminals, have not resulted in a match, but that the additional evidence would be analyzed when they were "sorted out."

“We believe that we may have some DNA there that may be our suspect, but we won’t know that until that DNA is separated, sorted out, maybe admitted to CODIS, maybe through genetic genealogy,” Nanos added.

No other updates about the DNA have since been revealed.

Acting U.S. Attorney General Todd Blanche address rumors of fallout between the local sheriff's department at the FBI in an interview with NewsNation earlier this month, insisting that the federal agency is committed full to supporting the work of the Pima County authorities, while noting that President Donald Trump continues to be briefed on any progress being made.

"The FBI has worked closely since the day that this happened with the local law enforcement, and there’s been reports of friction. I’ve seen those reports," he said. "We are here to help, and the FBI, President Trump authorized and directed us to do everything that we can to help that investigation.

"This is, at its heart, a local investigation because of the nature of this type of potential crime, but the FBI remains exacting where we’ve been, which is we’re ready, willing, and able to help as much as we can.

"We don’t like interagency squabbles. Nobody likes that. That doesn’t help the investigation. But we are in a complete cooperative mode with the local law enforcement."

When asked whether the FBI should take over the day-to-day running of the investigation, Blanche doubled down on his support of local law enforcement, telling the outlet: "Well, I don’t think or not think that. I think that any investigation like this should be done by a coordinated approach, right?

"There’s tools that the local law enforcement has that the FBI doesn’t have. So, in any investigation like this, it’s not somebody taking over or taking a back seat. It’s working together to solve the crime."

What is the full timeline of Nancy Guthrie's disappearance?

Nanos noted during a media briefing on Feb. 5 that, while times are approximate, his team has pieced together several pieces of evidence that indicate Nancy's movements—and the timeline of her apparent abduction.
