DB Cooper – Assessing the FBI’s 45-Year Investigation, Redux

By Bruce A. Smith

An excerpt from DB Cooper and the FBI – A Case Study of America’s Only Unsolved Skyjacking – 3rd Edition.

The FBI is arguably the world’s best investigatory organization, but they couldn’t solve the DB Cooper case. Why not?

I asked former SA Gary Tallis that question and his reply surprised me: “Because they haven’t found a body. If we had a body, all the answers would follow.”

But what happens to an investigation when there isn’t a body? Further, how should the FBI have proceeded when they had so little tangible evidence? It wasn’t an easy job, I admit. Losing evidence didn’t help, either. But large bureaucracies lose stuff and have less-than-adequate staff sprinkled throughout their organizations, even at managerial levels. So, after 45 years of investigating DB Cooper, how did they do?

In general, the FBI did many things very well, but there were obvious failures, clearly, like losing evidence. Overall, there seems to have been several distinct phases of the FBI’s Norjak investigation. The Initial Period lasted for several years, and featured a full-court press from the Bureau. In 1972, the FBI’s new director, L. Patrick Gray, gave Norjak the highest priority, writing “this case is to be vigorously pursued in all facets,” in his memo 164-81-3913, dated 9. 15. 72.

The FBI’s reach was massive: interviewing SOG troopers returning home from Vietnam, chasing copycats and ex-cons, and investigating skydiving centers, such as Elsinore. Add their tramping through the woods of Amboy searching hundreds of out-buildings and wood sheds, or interviewing cabbies, hotel clerks, and waitresses in Portland. They even interviewed middle-aged men named “Cooper” nationwide, so it’s hard to imagine what more could have been done.

However, by 1976 the Bureau’s momentum began to fade as the FBI realized they had very little critical evidence. But they had investigated 810 suspects, clearing 780, as per 164-2111, (dated 2. 5. 76). As a result, Phase Two emerged, where the FBI sought to generate some investigatory traction by adopting unusual measures, even desperate ones.

The FBI held a pow-wow that summer in San Francisco that included agents from Seattle, Portland, Las Vegas and San Francisco, along with top brass from Washington, D. C. Discussions concluded that their Norjak investigation was stymied. Worse, the Bureau felt if DB Cooper was apprehended, they didn’t have a strong case to convict. Simply, they didn’t trust their ten eye-witnesses – the three flight attendants, the two NWO gate and ticket agents, and the five passengers – due to variances in testimonies and sketches. In fact, the FBI decided officially not to show any more pictures to its eye-witnesses unless there was no other means of excluding a suspect. (164-81-7319, dated 1. 25. 77).

In addition, the FBI had no physical evidence other than the aftstair placard – remember this was before the money find at Tina Bar – and the 60-ish fingerprint samples from Reno were thought to be too smudged or too limited in scale to be legally probative.

In addition, they had lost confidence in their original LZ-A of Amboy, and determined the jump zone was ten miles further south, in the area of Hockinson, Washington. However, they didn’t tell anyone, apparently, nor conduct a search, as no one in Hockinson knew about their status in the Cooper investigation when I asked several townsfolk in 2019.

Hence, the FBI decided they needed DB Cooper to make a confession, as is described in a memo titled: “DB Cooper-19823.” To gain that confession the FBI considered offering DB Cooper an immunity deal while insisting on the return of the $200,000. The Bureau pondered announcing this arrangement as part of the annual Cooper extravaganza in November 1976, and began tasking agents to contact local media outlets. However, the FBI never followed through for reasons that are unknown at this time.

This malaise lingered until the money find in 1980 at Tina Bar, triggering Phase Three. After the initial push – digging for days at the beach and obtaining an analysis by Dr. Leonard Palmer – this momentum eventually floundered as well, partially due to Ralph Himmelsbach’s retirement two weeks after the money retrieval. His successor, Dorwin Schreuder, continued the passivity, as he told me he did not initiate any investigatory efforts in Norjak and only waited for the public to bring the Bureau leads.

Whatever the Seattle Division’s perspective was at that time towards the money find remains shrouded in secrecy, since Ron Nichols, the new Norjak case agent after Charlie Farrell’s retirement in 1977, refuses to discuss his investigatory efforts in any manner to this day. Regardless, nothing was found or advanced during the 1980s, so perhaps Nichols has nothing to say.

In addition, the FBI’s top witness, Tina Mucklow, was in her cloistered convent by then, and according to multiple FBI agents her memory was impaired, further dampening federal enthusiasm.

As a result, a second pow-wow was held in San Francisco in 1986. By then the Bureau’s Norjak lethargy was institutionalized. Nevertheless, another “Hail Mary” effort was concocted, pegged to the release of the movie: The Pursuit of DB Cooper. As part of their promotional campaign, Universal Studios announced a $1 million reward for information leading to the arrest and conviction of Dan Cooper. However, it didn’t create any leads, directly.

But Hollywood’s offer did flush-out a suspect. An unknown letter-writer – who signed his offer “sincerely not yours, d.b. cooper” – contacted the Bureau and agreed to surrender, but only if he could keep the film’s million-dollar reward. In addition, he wanted his ensuing prison term capped at just one-year – and he demanded placement in a minimum-security federal prison. Nevertheless, “d.b. cooper” offered to repay Northwest Orient the $200,000 ransom.

However, the FBI declined the offer, as per 164-81-8586.

Entering the 1990s, the Norjak investigation continued to slumber in a sleepy Phase Four, with the FBI reporting that only one lead a month needed follow-up, SE 164A-81, (dated 5. 19. 1998). Nevertheless, an effort was launched by the late 1990s to organize the physical evidence. Sadly, the Bureau discovered that all of the material stored in Las Vegas has been “destroyed,” including the cigarette butts, per SE-164A-81-9288.

At the same time, gadflies like Jo Weber, and citizen sleuths, such as Galen Cook, began stirring the pot, signaling the beginning of Phase Five. This chapter was characterized by a resurgence of interest by the public and joint action by the FBI. By 2003, someone in the Bureau decided to “process” the cigarette butts or gather DNA from the tie, and DNA samples from suspects were now sought. In addition, Galen sued the Bureau in 2004 for access to the Norjak files, and this may be considered to be the “official” starting date for a real partnership between the citizenry and the FBI. Larry Carr’s online contributions in 2008, and the creation of the Citizen Sleuth Team in 2009 can be considered the high points of this period.

After the FBI closed the case in 2016, Phase Six began, where the general public, Tom Kaye’s Citizen Sleuths, and private investigators, especially Eric Ulis, continue the hunt for DB Cooper.

Assessing these phases, we can identify particular people, places, and events that have been problematic. Some investigatory elements might have resolution, some might not. But first, let’s talk about the Bureau’s successes:

What the FBI did right:

Initially, the Bureau did all the basics – maintaining passenger safety, securing the airliner and physical evidence, and debriefing the passengers at Sea-Tac and the crew in Reno. Later, the FBI did what it does so well – a massive, blanket investigation. They interviewed airport employees to ascertain where Cooper came from and when, along with dozens of skydivers and soldiers, and all those forlorn fellas who had been thrown under the bus by their broken-hearted ladies.

The dig at Tina Bar was conducted adequately, in general, as all evidence indicates that the search was done thoughtfully and comprehensively. Yes, they could have taken more pictures, especially of the shards.

Larry Carr’s actions are stellar, as well. Establishing the Citizen Sleuths was superb, as was his posting on Internet chat rooms.

But there is room for improvement. High on the list are lost or poorly collected evidence, such as the fingerprints. Here’s a specific list:

Deficiencies in the Investigation

   1. Lost Evidence

       Where are the cigarette butts? If lost, is anyone looking for them? Were they processed for DNA analysis, as indicated by case agent Larry Carr? If so, where is the paperwork? Also lost, apparently, are the in-flight magazines and cocktail glass that Cooper handled, as are the hair samples and textile fibers collected off the headrest of seat 18-E.

   2. Clip-on Tie

       Why did it reportedly enter the Seattle evidence cache four days after the hijacking? Where was it for that time? Was the chain of custody broken? What does it mean that no one involved in the evidence retrieval in Reno, specifically Tina Mucklow, Red Campbell, Jack Ricks, John Norris, and Alf Stousland, could remember the tie when questioned by Bernie Rhodes in the 1980s? To what extent, if any, did the FBI follow-up on the Citizen Sleuth’s discovery of titanium and rare earth minerals on the tie, beginning in 2009? Why isn’t that a priority now? Simply, it appears the FBI has ignored this evidentiary find.

3. Reno, fingerprints

       How many prints were obtained in the Reno search, and by whom? Where were they found? Have any reconstructions of the fingerprints been undertaken? Did a “second sweep” actually occur at Sea-Tac?

4. Reno, behaviors of FBI agents

       What caused the memories of the Reno agents to be forgetful, fuzzy or in conflict with each other? Were these agents “victims of some strange post-hypnotic suggestion,” as Bernie Rhodes has written? Did MKULTRA play a part in Norjak?

5. Radar Findings and Flight Path Issues

       Why is the Flight Path still in doubt? Why was Cliff Ammerman never interviewed by any FBI agent? What did SAGE radar record the night of November 24, 1971? Why do the Seattle transcripts have over one-dozen redactions? Why did NORAD tell Major Dawson to “back off” the F-106s, and pull out the chaff?

6. Ground Search

       Why was the ground search of LZ-A called off on Monday, November 29, 1971? After all, the ground teams only covered one square mile out of dozens potentially. Why did Seattle FO tell FBI HQ that there was too much snow on the ground to continue when there was no snow reported in the LZ-A by local officials. Why did the FBI switch the LZ-A to Hockinson in 1976? What kinds of search ensued?

7. SOG and 727s

       What was the role of 727s in the Vietnam War? Were they used to deploy soldiers such as the MAC-V-SOG troopers into combat? Did any combat units utilize techniques similar to those of DB Cooper, i.e.: jumping from a 727 with flaps at 15, gear down and locked, etc.?

8. Money Retrieval

       How many shards of money were found at Tina Bar? Where are they, currently, especially the larger ones in the 2-3-inch category? What kinds of follow-up were done along the Columbia River, i.e.: fishermen interviewed, other sites dug-up, etc.? What does the discovery of springtime diatoms on the money mean?

9. Richard McCoy

       What was he doing in Las Vegas on November 24–25, 1971? What was he doing there on November 2–3, 1971? How did he learn the details of hijacking an airplane? What was his relationship with “Dan Cooper?” Why did the Seattle Division accept McCoy’s alibi that he was home with family on Thanksgiving, refuting the findings from Salt Lake City FBI agents? How did he get the $6,000 in late 1971 that funded his family’s trip to North Carolina?

10.  Earl Cossey

       What was the true role of Earl Cossey in the Norjak investigation? Did he actually own the “back” parachutes delivered to the hijacker, as he claimed? Did Cossey influence the FBI’s perspective that Cooper was an inexperienced skydiver? Why did the FBI flip-flop on their assessment of Cooper’s skills? Why was Cossey murdered? Why is that crime still unsolved?

11. Care of Evidence

       Why weren’t pictures taken of the parachutes? Why weren’t pictures taken at Tina Bar of the shards, and the specific dynamics of the money retrieval, such as the beach slope, the actual location, close-ups of shards buried at three-feet, etc.

12. Suspects: Unanswered Questions –

         What was the real reason Robert Rackstraw was dismissed as a suspect in 1979 after the FBI arrested him in Paris, France on his return to the United States from Iran? Just fingerprints? Did E. Howard Hunt, or someone like him, play a role in Norjak?

13. What was the full impact of the DB Cooper skyjacking?

         Did it affect national politics? Did it enhance the efforts to federalize airline safety?

14. Would the FBI be willing to participate in a public debriefing of Norjak?

         Will the FBI send agents such as Larry Carr and Curtis Eng to CooperCon 2021 to anchor a panel discussion assessing the FBI’s investigation?

Lastly, why aren’t these questions enough to re-open the case? How can the FBI reasonably walk away from Norjak with this amount of doubt?

We may always have the aroma of a cover-up lingering over Norjak. Certainly, there have been numerous instances of sloppy police work, like losing evidence; systemic deficiencies within the FBI, such as Hoover’s rigid model of case management; and problematic decision-making. But does that mean there has been an actual attempt to prevent us from knowing the truth of DB Cooper?

There is no direct evidence that supports a cover up, but Norjak does seem compromised. Is it true that the FBI ran out of credible leads and examined all available evidence by 2016 when they closed the case? If so, they should be able to answer all the above questions.

Besides these specific concerns, perhaps the greatest issue in Norjak is the failure of leadership. This issue has impacted the case in every dimension. At times, no one seemed to be in command of Norjak—certainly not in the early stages of the investigation. Farrell was in charge of Seattle-based activities, Manning on the ground near Ariel, Mattson in Portland and later Himmelsbach; and then Campbell and his Las Vegas-based crew in Reno.

But why didn’t Charlie Farrell jump on a plane and fly to Reno to ensure the proper retrieval of evidence, thus minimizing the predictable bureaucratic turf battles that followed?

Additionally, Farrell and his team worked in secrecy. The public knows little of his work. Farrell is reported to have penned a 300-page account of his experiences in Norjak, and Geoffrey Gray says he has read it. But my efforts to obtain access to a copy have been met by resistance from the Farrell family.

Similarly, why didn’t Ron Nichols jump in his car and drive the three hours to T-Bar to supervise the money recovery? Further, why did his boss, Seattle ASAC Jack Pringel, appear at T-Bar three days into the dig?

If Norjak was too big a case for a single agent, why wasn’t a Task Force developed? True, a quasi-force was formed in 1976 and 1986 when they met in San Francisco. But why wasn’t this group formalized to continue a joint, comprehensive investigation?

Another example of poor supervision was the care given to the evidence stored in Seattle. Before being shipped to HQ in 2016, the main pieces were stored loosely in a cardboard box that looked like it once held knickknacks from someone’s attic. Concerns over the chain of custody pepper Norjak as well, such as the clip-on tie being torn apart by the Citizen Sleuths, as reported by Geoffrey Gray in SKYJACK.

These breaks in the chain of custody are serious concerns. DB Cooper aficionado Mark Metzler, an attorney in the Bay Area, offers a cogent view of the matter:

    The FBI has been amazingly cavalier about the handling of physical evidence (in Norjak). It’s not normal practice. As a defense lawyer, when I had my experts examine physical evidence or run lab tests the prosecution enforced strict protocols so that the custody chain was unbroken and fully documented and that contamination or alteration of evidence was prevented.

    Even in minor cases this was how things were handled. I represented a ghetto bar owner who the cops hated. He was arrested for serving alcohol to a minor. It was a major hassle just to get a sample of the drink which was preserved. My lab had to sign for the sample and document its handling at every step. The prosecution wisely only gave my lab a portion of the sample so that they had a control if my findings were later to be disputed. My client got really lucky. My lab tested zero alcohol. When the police lab repeated their test, they found the same thing. Case dismissed.

    It might be that the FBI has some undisclosed evidence that has been very carefully handled and that is highly probative in identifying Cooper, enough so that a conviction could be secured without any other evidence. Cigarette butts might fit this description. It just makes no sense that they would be ‘lost.’

    Peterson, a highly qualified suspect, was ruled out on DNA. Maybe it wasn’t tie DNA but cigarette DNA, which would be more confidently linked to DB Cooper.

In addition, there was an uncanny passivity to the FBI’s work for much of the 45 years, even during the “active” times. Ralph Himmelsbach never interviewed Tina even though she moved to the Portland area after the skyjacking, circa 1979, and then spent decades in Eugene, just two hours south. Is this the proper handling of a primary witness in a major case? More troubling, Himmelsbach’s book reveals—and Dorwin Schreuder confirms—that for much of the Norjak era the Portland Division had a reactionary stance to the investigation, and only responded to leads as they came in to the office. Similarly, Seattle agents, such as Bob Sale and Sid Rubin, have also indicated that the Cooper case was near-dormant in the Seattle FO between the money find in 1980 and the resurgence in the late 1990s.

Further, did silence on the details of the case really serve the investigation? Why didn’t any FBI agents attend the DB Cooper Symposium in 2011 or 2013, or the CooperCons in 2018 and 2019? What did that avoidance achieve? What kind of investigatory integrity did that maintain?

At times, it appears that FBI agents don’t talk with one another, either, even when working on the same case. Researcher Galen Cook has a telling story on this subject:

    Seems like the NORJAK agents die by the vine, but DB Cooper lives on. The Bureau must hate that. No one ever hears from Carr since he left (in 2010). He e-mailed me about six months after I started talking with Eng, but Eng wasn’t too enthused that I was still talking with Carr about the case. Led me to believe that the agents aren’t necessarily on the same page, and rather territorial of their own turf, even among other agents.

Part of this non-sharing with fellow agents was fostered by J. Edgar Hoover. As discussed previously, Hoover awarded cash bonuses to agents who busted tough cases, so field agents had an incentive not to share since it could cost them money. Plus, we have the pressures seeping from the mundane area of internal politics: promotions based upon performance, and assignments determined by one’s status within the office.

As for my relationship with FBI agents, when I ask questions beyond their initial set story they balk. I call it the “One and Done” scenario. I get one good interview—usually a recitation of their well-rehearsed narrative—then, nothing. Follow-up phone calls and emails go unanswered. Thus, I strongly suspect that what I was told initially was a spin job, and they don’t want me to scratch beneath the surface.

More troubling, formal communications between the FBI and journalists became seriously strained in 2015 when the FBI developed a new policy for media relations. Simply, the FBI stopped talking to anyone about Norjak unless the contact was specifically authorized prior. After years of exchanging increasingly opaque emails with PIO Ayn Dietrich-Williams, she finally stated the obvious on December 7, 2015:

    The FBI’s media policy prohibits discussing ongoing investigations unless a   release is specifically thought to have potential benefit to the investigation.

    …I understand your continued interest in our investigation and apologize that I will not be able to share additional information to answer your questions.

Nevertheless, I have not abandoned all hope in the FBI, and I will be providing them with a “Special Edition” of this book, complete with phone numbers and contact information for all of the major figures of the case. At least then, the Bureau will have a comprehensive overview of the case for future investigators to consult.

Of course, they can call me anytime for assistance.

    Great read Bruce ! Regarding the below snippet:

    “But Hollywood’s offer did flush-out a suspect. An unknown letter-writer – who signed his offer “sincerely not yours, d.b. cooper” – contacted the Bureau and agreed to surrender, but only if he could keep the film’s million-dollar reward. In addition, he wanted his ensuing prison term capped at just one-year – and he demanded placement in a minimum-security federal prison. Nevertheless, “d.b. cooper” offered to repay Northwest Orient the $200,000 ransom.

    However, the FBI declined the offer, as per 164-81-8586.”

    – Was this letter kept by the FBI? Has the Cooper Vortex seen the letter?
    – It sounds as though it was taken seriously by the FBI, did the letter writer offer a piece of information that only d.b. cooper would know thus convincing the FBI it was authentic ?
    – Was this contact similar to and around the same time as the contact made to Max Gunther by “Dan Claire”?
    – Did this letter spark a back and forth correspondence where the FBI formally declined the offer or was it just the one letter which the FBI simply ignored ?
    – Or am I giving too much credence to this tidbit ? i.e. it’s most likely just an opportunist trying to get a million bucks for the low price of spending 1 year in prison.

    Thanks Bruce !


  2. Eric Ulis says:

    You mention that Sheridan Peterson was ruled out by DNA. I am unaware of any such thing. To the contrary, part of what makes Sheridan a compelling suspect is that he was never publicly eliminated by the FBI via the DNA as were both LD Cooper and Duane Weber.

  3. brucesmith49 says:

    Yes, we disagree on this Eric, as I interpret SA May Jean Fryar’s comments differently than how she re-iterated them to you. It was quite clear to me in my conversations with her that she was convinced the information she had received from her colleagues at the FBI concerning Petey’s DNA had ruled him out as DBC.

  4. Eric Ulis says:

    Mary Jean has been very clear that she has no idea if Sheridan’s DNA was even tested. In fact, she stated as much on the show in her discussion with Sheridan. Obviously there was some manner of miscommunication when you spoke with her. Nonetheless, unless she has categorically changed her story 180 degrees, no one has ever heard of Sheridan being cleared by the FBI either publicly or privately. If so, I’d love to hear from them.

  5. Johnnie Green says:

    This pretty well sums up what everybody has to say to Robert Blevins.

    • Gypsy23 says:

      Love it, Johnnie. A proper response to Blevins. Along with this….. 💩.
      Blevins really thinks that Bruce would get involved with anything that Blevins is doing?

  6. Albert R Shumate says:

    DB Cooper
    Drank Bourbon, Smoked which describes about anyone involved Special Warfare at that time. It was never about the money. The roots of this were a Bar Room Bet. The Bar Room was at Port where contractors hung out.
    Whatever money left when he got back to the Bar was split with the ones involved in the bet and some day somebody will be cleaning that oddball uncle or granddad’s stuff and will find money, they did not know they had.
    Did Cooper have the skills to survive, yes and he knew how to jump in that he learned at Fort Benning. There were some exercises where high altitude was involved.

  7. Marla says:

    Tremendous article and superbly written. Your work has chronicled the FBI’s investigation better than any DB Cooper book to date. Your insights are a treasure!

    • Johnnie Green says:

      The real reason that Blevins looks forward to camping trips with his fictitious campers:
      He imagines everyone else cleaning HIS toilet.

      • Gypsy23 says:

        Everything is suspiciously fictitious when it comes to Robert Blevins. Liars typically give endless streams of explanations about things, primarily to cover-up for all the previous lies. In Blevin’s case, the fiction is long:
        Fictitious camping permits by the government. Fictitious campers. Fictitious repair abilities in janitorial work. Fictitious conversations with FBI agents. Fictitious commentary about DB Cooper. A fictitious suspect. Fictitious reasoning skills. A fictitious resume’. Fictitious self-departures from the DZ. Fictitious references to other, more qualified writers and journalists. Fictitious accounts of friendships with his alleged co-author. The ONLY thing that appears to be non-fictitious is Blevin’s ability to write everything in fiction. The complete and shameless old liar.

  8. Emile says:

    Shutter’s forum has been taken over by R99 and Ulis. Shutter is saying nothing letting them run amuck. Shutter has lost control of his forum or is complicit in the takeover. Georger and others have been nullified, with a vengeance!
