TUCSON, Ariz. — Callahan Walsh, co-host of the popular true-crime television show ‘America’s Most Wanted’, recently shared insights with Fox News Digital regarding the perplexing disappearance of Nancy Guthrie. Walsh, who is extensively involved in missing persons cases, described Guthrie’s case as particularly unusual.

Walsh noted the rarity of missing senior cases, explaining that when elderly individuals go missing, it’s often due to them wandering off or becoming lost while driving. The ongoing search for Guthrie, he emphasized, has yet to yield results, making it a unique and challenging case.

“The investigation into Nancy’s disappearance has been a rollercoaster, oscillating between hot and cold leads,” Walsh explained. “Our deepest hope is to find Nancy alive, so she can reunite with her family.”

Callahan Walsh’s personal connection to missing persons cases runs deep. His brother, Adam Walsh, was kidnapped and tragically murdered at the age of six back in 1981. Alongside his father, John Walsh, Callahan co-hosts ‘America’s Most Wanted’, a show dedicated to solving true-crime mysteries. He recalled the anguish his family endured, stating that “the uncertainty was the hardest part” when Adam disappeared.

“During the two weeks we searched for Adam, my parents were sleepless and desperate to bring him home. We understand the pain the Guthrie family is experiencing,” Walsh shared.

“The two weeks that we looked for Adam, my parents couldn’t sleep. They would do anything to get Adam back, and we know what the Guthrie family is going through,” Walsh said.

Walsh also serves as the executive director of the National Center for Missing and Exploited Children (NCMEC) and said he’s thankful that, amid her family’s pain, Savannah Guthrie is willing to help others. The NBC “Today” co-host pledged $500,000 to the NCMEC, a donation that Walsh said “means everything” to the nonprofit.

“Children are our most vulnerable population, but they’re our most important population. They’re our future,” Walsh said. “Thanks to the generous donation… we can stand by more families.”

“We also know that we are not alone in our loss,” she said in the video. “We know there are millions of families that have suffered with this kind of uncertainty.”

Walsh said that as a nonprofit, this donation allows them to “better serve the families and the children that [their] mission is out there to do.”

He added: “Not only will this money go directly to the programs that help bring these kids home, but will also go to raise awareness on other cases that aren’t getting the attention they deserve.”

Savannah Guthrie also offered a family reward of up to $1 million for the recovery of her mother Nancy, after consultation with law enforcement. 

Walsh said that this reward may be “the motivating factor” that gets a person to come forward with new, credible information to law enforcement.

“This amount of money is life-changing. This could really get somebody to second guess why they’ve not been truthful about what they know and could be the reason that they finally come forward with that piece of information that the family is desperate for, that law enforcement is desperate for,” Walsh said. “Information that could absolutely lead to not only Nancy’s recovery, but the apprehension of the suspects as well.”

Walsh said sifting through the tips can be a challenge, but they often tip the scales in a case.

“They’ve helped us recover nearly 1,200 fugitives, the worst of the worst… and it’s because of the public tips that have been provided,” Walsh said. “I always say, it’s like looking for a needle in a stack of needles.”

He explained that it’s better to have more tips than to have no tips at all.

“As tiny as you might think it is, it might be that little bit of the puzzle that law enforcement has been looking for this whole time,” Walsh told Fox News Digital.

The NCMEC works with victims, their families and law enforcement, among others, to not only find missing children, but to also stop “child sexual exploitation” and “child victimization.”

Walsh told Fox News Digital the group has helped recover more than 450,000 children since its inception and has various resources such as support groups and case managers. The group had a 91% recovery rate in 2024 for all cases reported to them, according to its website.

Nancy Guthrie was last seen on Jan. 31 and has since been missing after she vanished from her Catalina Foothills home in Tucson, Ariz.

Police have not identified any person of interest, despite releasing Nest camera footage from her home.

“We know her family will never give up hope,” Walsh said. “We will never give up hope and law enforcement won’t either.”

Anyone with information in the case is asked to dial 1-800-CALL-FBI.
