Nancy Guthrie's untouched $1.2M reward is a reference in itself for a retired FBI informant.

INTERMEDIATE: TUCSON, Ariz. — The fact that a seven-figure bounty remains unclaimed nearly six months after the alleged abduction of Nancy Guthrie from her Tucson home in the Catalina Foothills neighborhood tells one veteran detective that if the masked robber on her porch had help, it came from a small, tight-knit group.

“That tells me the circle you know is very small, and whoever is in it is bound by something more powerful than money: blood, fear, shared exposure,” said Jason Pack, a retired FBI negotiator and surveillance agent who has been following the case closely. “Those bonds hold. Until they hold.”

The more people know about the crime, the more likely someone will come forward to claim the reward, he said. The total rewards in the case are more than $1.2 million – and none have been claimed in the 179 days after Guthrie's alleged kidnapping.

“That kind of money usually gets someone out of almost any group,” Pack told Fox News Digital. “It hasn't arrived yet.”

Rather than an end, Pack sees the untapped reward as another clue.

“In my experience, a significant share of cases like this break aside,” he said. “A person gets arrested for something unrelated and then starts talking. Relationships end badly. A person's conscience finally overcomes their fear. Six months is a long time to hold something so difficult, and people who have done this for six months already see a change in themselves.”

Pack said it appears the kidnapper or kidnappers tried to plan a crime – and they didn't do it right. At least one suspect is believed to have carried out the crime from the house. He was wearing a ski mask, long sleeves and gloves, and covered the lens of his Nest doorbell camera – which was missing when police arrived the next day.

“When it went bad, and I believe it went bad quickly, they didn't have a plan for that either,” he said. “Everything reads to me like an improvement on a failure, not an expert making a plan.”

Guthrie, the 84-year-old mother of “Today” host Savannah Guthrie, relies on heart medication and has a pacemaker. He has limited mobility – and a close-knit family.

“He had dinner with his family Saturday night, went home, and didn't come to church the next morning,” Pack said. “The one we're talking about. Not the case number. My mother was supposed to be at church.”

Although the suspects made serious mistakes, he said that does not mean that the investigation has stopped.

Pack also shared a direct message to Guthrie's neighbors and residents of surrounding communities:

“Go back and check your cameras from that time. Doorbell, security, dashcam,” he said. “A lot of systems archive further away than people realize. If you've been through the area that night, pull your dashcam files.”

If you see something but don't have video, you should still speak up, he said.

“And think about the people in your life. The person who left town. The person who behaved in February and never came back,” he said. “You don't have to be sure. That's not your job. It's your job to fix it [the investigators’ job].”

In May, a source familiar with the case told Fox News Digital that the FBI is bringing new technology to the investigation.

Pima County Sheriff Chris Nanos, whose department is the lead agency, said in an interview this week that he still believes the case will be solved.

“We have a lot of DNA to sort out,” he said in an interview that aired on “Today.” “We have a lot, in terms of video evidence, to look at.”

And they spent months studying material from DNA and video and other bodies that the public had never seen, Pack noted.

“I've watched cases break in the eighth month, the 14th month, the 30th month,” said Pack, whose FBI career spanned 21 years, 11 of them as an interviewer. “Most every one of those families had given up believing it would ever come.”
