Who is Callahan Walsh? Brother of slain child Adam Walsh weighs in on Nancy Guthrie inquest, ‘Things have gone from hot to cold…’

during the investigation Nancy Guthrie “America’s Most Wanted” co-host Callahan Walsh told Fox News Digital that “there’s a lot to note” about the disappearance. Walsh, who closely follows various missing persons cases, noted that the fact that Nancy has not yet been found makes it “very unique.”

Walsh also said not many seniors are missing, adding that they often get lost or get into their cars and have no way to navigate their way home.

“The ups and downs of this investigation, from hot to cold to hot again [and] It’s cold again,” said Walsh. “We’re hoping Nancy will be found alive [and] She was taken home and reunited with her family. “

Walsh serves as executive director of the National Center for Missing and Exploited Children (NCMEC).

He revealed that his parents found “not knowing to be the hardest part” after Adam’s disappearance.

“My parents couldn’t sleep the two weeks we were searching for Adam. They would do anything to get Adam back and we knew what the Guthrie family was going through,” said Walsh.

Walsh also commented on the $1 million reward offered by Nancy’s family for her recovery. He explained that this may have been a “motivating factor” for people to come forward with credible information about Nancy.

“This money can be life-changing. It really makes people second guess why they were not truthful about what they knew and may be the reason why they end up providing information that the family desperately needs and law enforcement desperately needs,” said Walsh. “This information will absolutely not only help Nancy recover but lead to the arrest of a suspect.”

Despite days of searching, authorities have not released the names of any suspects.

“We know her family will never give up hope,” Walsh said. “We will never give up hope, and neither will law enforcement.”

Walsh said of his work with NCMEC that while screening tips can be a challenge, they often tip the balance in cases.

“They’ve helped us capture nearly 1,200 of the most serious fugitives … and that’s because of the public tips we gave them,” said Walsh. “I always say it’s like looking for a needle in a pile of needles.”

He also points out that more tips are always better than no tips at all.

“Even though you might think it’s small, it could be just a small piece of the puzzle that law enforcement has been looking for,” said Walsh.

Authorities believe Nancy was abducted from her home in Tucson. Pima County Sheriff Chris NanosBefore said the Guthrie family “has shown nothing but cooperation and kindness and that they are the victims in this case,” adding, “To suggest otherwise is not only wrong, it is cruel. The Guthrie family are victims, plain and simple.”
