It has been more than a month since Nancy Guthrie disappeared, and there have been no credible leads about what happened to her or where she is. In fact, at this point, most people involved with the investigation and even her family seem to be quietly preparing for the worst. But where does that leave Nancy’s family?

Rob Shuter reported that Savannah Guthrie returned to her mother’s home and will now be heading back to New York after saying goodbye. Alongside her sister Annie and her brother-in-law, Savannah visited the memorial outside Nancy Guthrie’s home.

“She didn’t want it to be a goodbye,” a source close to the family told Shuter. “But she knows she can’t live in limbo forever.” In the memorial, the signs still read “Please come home.”

“That sign breaks her every time she sees it,” the insider said. “She still believes. She just doesn’t know what she’s believing for anymore.” And the source also told Shuter, “There were no words left,” about Savannah and her siblings. “Just love. Just heartbreak.”

But life, sadly, doesn’t stop. “She has to return to her life,” the source added, “But she’s leaving a piece of her heart in Arizona.”

Not that long ago, Savannah said on social media that she has “accepted” that her missing mother “may already be gone.”

“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,” Savannah said on a video from February 24. “We still believe in a miracle. We still believe that she can come home. Hope against hope. As my sister 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 her beloved brother, Pierce, and with our daddy,” Savannah added. “And if this is what is to be, then we will all accept it. But we need to know where she is. We need her to come home.”

The reward for information about Nancy Guthrie’s disappearance now stands at $1 million. Law enforcement has released surveillance video and photos of a suspect, but has not been able to identify the person.

Volunteers have been helping search for Guthrie, particularly in the area close to her home. Tucson resident Lupita Tello, a member of the Mexico-based volunteer search group Madres Buscadoras de Sonora, broke down how they search for USA Today. She poked at the dirt outside of the home with a sharp metal rod soldered to a handle, wiggled the rod around, pulled it out, and smelled it. “If it smells bad like something decomposed, that’s where we start,” she said.

Savannah Guthrie’s mother Nancy missing over a month, $1M reward remains unclaimed

TUCSON, Ariz. — Savannah Guthrie was spotted outside her mother Nancy Guthrie’s home on Monday morning, viewing flowers left by supporters.

The Fox Flight Team drone captured video of her and other family members viewing the items left by well-wishers. Additional video of the visit shows Annie Guthrie, Savannah’s older sister, sobbing during the visit before she, her husband and younger sister placed yellow flowers at the growing display in her mother’s honor.

She also left a note addressed to her mother and signed by her and her husband.

In a new post on Instagram shortly after her visit to the site, Savannah Guthrie shared a photo of the memorial featuring the vibrant yellow flowers.

She wrote: “we feel the love and prayers from our neighbors, from the Tucson community and from around the country. please don’t stop praying and hoping with us. bring her home.”

It’s now been more than a month since Nancy Guthrie’s suspected abduction from her home in the Catalina Foothills.

The Pima County Sheriff’s Department and Federal Bureau of Investigation (FBI) have shifted resources as the case enters its fifth week without an arrest or publicly named suspect.

Sources said that on Monday, the case was handed off to a task force featuring Pima County homicide detectives and FBI agents. Sheriff Chris Nanos has not held a news conference since Feb. 5.

“This remains an active investigation and will continue until Nancy Guthrie is located or all leads have been exhausted,” a PCSD spokesman told Fox News Digital. “The Pima County Sheriff’s Department is refocusing resources to detectives specifically assigned to this case. As leads are developed and resolved, resource allocation may fluctuate. PCSD will maintain a patrol presence in the Guthrie neighborhood.”

Investigators are still digging through tens of thousands of tips and leads. There are thousands of hours of video. DNA leads remain under investigation. Authorities have yet to publicly reveal what other items worn by a suspect seen on Nancy’s Nest doorbell camera have been identified aside from his Ozark Trail backpack.

They are also reportedly still looking into a Ring camera video taken on a back road out of Nancy’s neighborhood, about 2.5 miles from her home, which leads to East River Road, a major cross street.

The video, first obtained by Fox News Digital and provided to authorities last week, was recorded on a Ring camera roughly a seven-minute drive from Guthrie’s address — and it is still part of the investigation, Savannah’s network NBC reported Monday.

One of the vehicles it shows was recorded at around 2:36 a.m. on Feb. 1, which is roughly eight minutes after Guthrie’s pacemaker last synced with her iPhone, according to the sheriff’s timeline.

“I think this is the best lead probably since day one,” said retired Pima County Search and Rescue Commander Bob Krygier. He told Fox News Digital the footage is worth serious follow-up but cautioned it may ultimately prove unrelated.

“I think it’s a great little bit to follow up on. If I had to guess, I would say it’s probably not related,” he said, adding that investigators would likely review several weeks of footage to determine whether the cars follow normal overnight routines.

“It’s not just a road that you stumble upon,” he said. “You have to be very planned to go in there.”

Retired NYPD detective and national security expert Pat Brosnan reviewed the video with his team. He told Fox News Digital they believe the vehicle seen at 2:36 a.m. is a Kia Soul, based on its slanted roof, window design and rear-quarter glass. He also noted the vertical brake lights.

The combined reward is more than $1 million and has yet to be claimed.
