An expert on kidnappings said Savannah Guthrie’s family’s latest video offering to pay ransom shows they are responding as if her mother Nancy Guthrie is alive and being held, calling it a clear, unconditional signal to whoever is on the other end.

Retired FBI agent Jason Pack, who has worked abduction cases, told The Post that the message released Saturday by Savannah Guthrie and her siblings Camron and Annie stripped away any ambiguity.

“That family got on camera and said ‘we will pay.’ No conditions, no fine print, no lawyers talking in circles,” Pack said.

“Just a mother’s children saying bring her home and we’ll do what we need to do.”

Pack said the wording marked a decisive turn, shifting pressure off the family and onto whoever has Nancy.

He pointed to Savannah’s use of the word “celebrate” as intentional, signaling that the family wants their mother back alive and is not seeking revenge.

“That’s a family telling whoever’s on the other end of this… we’re not out for blood. We just want her back,” he said.

He noted the family’s statement appears to answer a reported Monday deadline, set by whoever sent the message.

“The family has answered. They said yes,” Pack said. “So now either this thing moves forward or it doesn’t — and if it doesn’t, it won’t be because the Guthries didn’t hold up their end.”

Former CIA official Tracy Walder, who was also a special agent for the FBI, offered a more cautious read, focusing on the tone and phrasing of the video.

She described it as carefully constructed and responsive to an external message, noting phrases like “very valuable to us” and “so we can celebrate her” are unusual in everyday speech.

Walder said the delivery was more muted and somber than the family’s first video.

The video may signify that the family has been given proof of life for their 84-year-old mother, according to a former head of the NYPD’s hostage negotiation unit.

“The fact that they said that they will pay, that goes against law enforcement protocols unless we have proof of life,” Lieutenant Jack Cambria told The Post.

Law enforcement can only advise a family on what to do in these dire situations, and it’s possible the family decided on their own to pay, said Cambria, who commanded the NYPD Hostage Negotiation Team from 2001 to 2015.

“The human side of it, the emotional side, I get it — it’s their mom, and they want her back,” he said.

However, Cambria honed in on a key line from the recording that may indicate the family received fresh communication from the kidnapper.

“Savannah did say we understand. Understand what? She obviously got some kind of message out of this, and they’re just not relating to the public what that is.”

Cambria said that if the family goes ahead and pays the ransom, there’s a chance the captors may keep their word if Guthrie is still alive.

However, if she is dead, he warned they are likely to take the money and run — especially if payment is demanded in Bitcoin, which is notoriously hard to trace.

“They’ll leave law enforcement to fend for themselves — good luck finding the body,” Cambria said.

Private investigator Toby Braun said the family’s decision to release a second public video does not necessarily indicate progress in the case.

“The release of a second family video doesn’t suggest progress,” Braun said. “In most abduction cases, families go public again when there has been no communication and no proof of life.”

Braun said that if there had been verified contact or meaningful movement behind the scenes, the family’s strategy would likely have shifted away from public pleas. “The continued public pleas point to silence rather than resolution,” he said.

He also said renewed law enforcement activity at Nancy Guthrie’s home is consistent with an abduction investigation, not a voluntary disappearance.

“Investigators typically revisit a scene when new information surfaces that needs to be confirmed or ruled out,” Braun said. “That kind of follow-up reinforces that authorities are not viewing this as a voluntary disappearance.”

From a negotiation standpoint, Braun said ransom efforts cannot advance without proof of life, warning that each passing day heightens concern given Guthrie’s medical vulnerabilities.

“Without communication and proof of life, there is no leverage and no way to ensure the victim’s safety,” he said. “Each passing day increases concern, particularly given her medical vulnerabilities.”
