In November 2017 , the FBI released a typed letter , claiming to have been written by the infamous skyjacker , '' Dan Cooper '' . On November 24th 1971 , Cooper obtained $200,000 through hijacking a 727 Jet Airliner , and jumped out of the aircraft with two parachutes , at 10,000 feet in a storm somewhere in the region of Portland , Oregon . He was never seen again .
In the wake of Cooper's exploits , correspondences from a person claiming to be Cooper started to emerge .
It is not a newly found suspicion that some or all of these correspondences may be from the hand of the Zodiac Killer .
In examining the notes and letters , it is the intention to shed more light on this possibility .
We start with the most recently released correspondence , released by the FBI sixteen months after they officially closed down the D B Cooper case , in July 2016 .
This typed letter , is now known as the '' I knew '' letter , and dates from December 11th 1971 . As four copies , it was sent to the Washington Post ; New York Times ; Seattle Times , and Los Angeles Times newspapers .
The '' I knew '' typed letter , from December 11th 1971 :
'' I knew from the start that I wouldn't be caught . I didn't rob Northwest Orient because I thought it would be romantic , heroic or any other of the euphemisms that seem to attach themselves to situations of high risk . I'm no Robin Hood . Unfortunately do have only 14 months to live . My life has been one of hate , turmoil , hunger and more hate . This seemed to be the fastest and most profitable way to gain a few fast grains of peace of mind . I don't blame people for hating me for what I have done , nor do I blame anybody for wanting me to be caught and punished , though this can never happen .
Here are some ( not all ) of the things working against the authorities : I'm not a boasting man . I left no fingerprints . I wore a toupee . I wore putty make-up .
They could add or subtract from the composite a hundred times - and not come up with an accurate description , and we both know it . I've come and gone on several airline flights already and am not held up in some obscure backwoods town . Neither am I a psycho-pathic ( sic ) Killer . As a matter of fact I've never even received a speeding ticket .
From a cryptographic perspective , the '' I knew '' letter becomes very interesting , when we view the '' for the copying of '' notes , at the bottom of the letter .
The four designated newspaper's names are all listed , and with a unique code assigned to each newspaper . It does seem more than likely that each newspaper was given something extra and unique , such as a picture or newspaper cutting , also . Hence , the unique assigned code held a link to the extra item , enclosed in each envelope .
To date , this is what the FBI have so far revealed , with respect to the bottom of the '' I knew '' letter :
Wash Post - 717171684*
New York Times - TBA
Seattle Times - TBA
Los Angeles Times - 7698QA2753
So , its a given that no coded message has been released by the FBI , for the New York Times and the Seattle Times , where we are offered '' TBA '' - To Be Established .
But , the designated codes for the Washington Post and Los Angeles Times have been released , and it is these two , that require deciphering .
Both '' 717171684* '' and '' 7698QA2753 '' have 10 characters found on a conventional keyboard . So , it is likely that a 10-character code will be offered for all and each of the 4 newspapers .
Where might we find a Zodiac link , if there is one ? Which Zodiac correspondence , might give us a derivation clue to the 10-character codes ?
Well , in true crossword puzzle and cryptic tradition , the initial clue might well be found , on reading horizontal wording , in vertical fashion .
Bearing in mind , that '' D B Cooper '' is at the very centre of the subject matter , we can see : '' Wash New Sea Los A '' .
'' Wash new sea loser '' ( ? ) , as a subliminal erasing of the man who jumped out of an aircraft . Perhaps it is the case of recognition that the author of this letter has decided to steal the mantle of the skyjacker , Dan Cooper , believing that he did not survive his jump from an aircraft .
Is the presumed hoaxer of Dan Cooper , the Zodiac Killer ?
Well , the Zodiac might well have been impersonating D B Cooper , if we can find that cryptographic link . And , it appears to be the case that the Zodiac's Dripping Pen Card of November 8th 1969 , fits the bill . Why ? Because the Zodiac bought in to the notion of having washed his pen , ready to do battle , once again , with the employment of a pen being '' mightier than the sword '' .
And what is a great significance of the Dripping Pen Card ? It accompanied the Zodiac's newly created 340 cipher .
So , perhaps it is the case that clues pertaining to the Zodiac's 340 cipher , will solve the 10-character codes assigned to the designated newspapers , in the '' I knew '' letter ( ? ) .
Since I , as Rubislaw 32 , claim the final solution to the Zodiac's 340 cipher , I decided to examine if a feasible and credulous solution might be found .
In examining the two codes offered , by the FBI , we observe :
Wash Post - 717171684*
Los Angeles Times - 7698QA2753
It does seem to me , that '' QA '' is only employed since '' Q '' in basic substitution , represents a number great than with single digits .
And this observation that '' QA '' is equivalent to '' 17,1 '' in basic alphabetic substitution , also gives the hint that these codes , should be partitioned into pairs of characters .
Los Angeles Times - ( 7,6 ) ( 9,8 ) ( 17,1 ) ( 2,7 ) ( 5,3 )
Now , these partitioned characters , become instructions , as such , with for example , ( 7,1 ) indicating ( Row 7 , Column 1 ) of the Zodiac's cipher solution . And ( 4,* ) indicating ( Row 4 , All Columns ) i.e. Row 4 in its entirety .
Hence , we can write out a basic solution , thus :
Wash Post - P P P T I INSERTED TEN CENTS
Los Angeles Times - U C T K S
And further , to translate the presumed abbreviations into lucid and understandable English Language .
Wash Post - '' Purchase Price Part - I Inserted Ten Cents ''
Los Angeles Times - '' You See - Thanks ''
So , if we write up , in full , what the FBI have so far released , we might infer that a part-solution is :
Washington Post - '' Purchase Price Part - I Inserted Ten Cents ''
New York Times - (...a 10-character code...)
Seattle Times - (...a 10-character code...)
Los Angeles Times - '' You See - Thanks ''
Interesting ,that it is possible that although each 10-character code is assigned to individual newspapers , the putting of the code solutions , back together again , might reveal a message with a slightly different conveyance of overall meaning .
In addition , that a message conveyed , with credulity , gives further credulity that the final solution to Zodiac's 340 cipher , as offered by Rubislaw 32 , is the correct solution....and that the Zodiac Killer was the author of D B Cooper's '' I knew '' letter , of December 11th 1971 .
( Postscript : After working on the codes , I researched the price of a daily copy of the Washington Post , in 1971 . It was TEN CENTS . )
Before again concentrating on those correspondences attributed to Dan Cooper , in the eventuality that he survived his 10,000 feet jump , it is worth noting a postcard that was mailed on May 23rd 1974 , from an area of Oregon close to where the postcard's picture denoted - The McKenzie River and the Three Sisters ( Three distinct neighbouring mountains ) .
Now becoming known as '' The Nixon Postcard '' , its author , who refers to himself as '' Concerned Citizen for Freedom ! '' , threatens Richard Nixon ( King ) with life of his daughter Tricia . This , in the wake of both the S.L.A.'s kidnapping of Patricia Hearst and newly released Watergate Tapes indicating Nixon's dishonesty to the American Public .
The address , on the postcard , is written thus :
RICHARD NIXON ''WHITE'' HOUSE PENNSYLVANIA AVE. WASHINGTON D.C.
This author becomes persuasively like the Zodiac , for a number of reasons , including a vertical reading of horizontal wording :
'' RICH WHITE PEN WASH '' - indicating an opinion about a possible Watergate cover-up , and a possible allusion to the Zodiac's Dripping Pen Card , of November 8th 1969 .
And so , in returning to the '' I knew '' letter , attributed to Dan Cooper , the vertical reading of '' Wash new sea loser '' or '' Wash new sea loss '' , does become a persuasive cryptic clue , in solving the codes assigned to the 4 newspapers .
And further , that the Zodiac , D B COOPER and '' Concerned Citizen for Freedom ! '' , are all the same authors .

Concentrating more on an aspect of handwriting comparisons , we could turn our attention to the note sent to The Oregon newspaper , with postmark December 3rd 1971 , and officially attributed to D B Cooper .
This is the note in full :
I AM RIGHT HERE IN PORTLAND ! AND THE $200,000 IS FOR REVOLUTION D.B.COOPER
The handwriting could be described as '' Box-like ''
A similar style can be observed on the Zodiac's Bus Bomb envelope , sent to the San Francisco Chronicle , with postmark November 9th 1969 .
But merely the part , reading : '' S.F.CHRONICLE ''
I was able to find very similar handwriting , in a lengthy letter sent to the Miami Herald , Florida , with postmark Daytona , August 23rd 1970 .
The letter is headed '' ASSINATION (sic) SCOOP '' , and presents a diatribe of complaints over ( then ) current government policy . In addition , the author threatens the lives of President Richard Nixon and Vice-President Spiro Agnew , and their families .
The '' ASSINATION SCOOP '' letter is signed : '' THE SOCIETY FOR THE CONSTITUTION AND A PATRIOTIC AMERICA ''.
Why Daytona Beach ?
Three reasons might be described as an geographic equilateral triangle of about 50 mile sides , with the three points as representing :
i ) Daytona motor racing track
ii ) Orlando recreation , including Disney World
iii ) Cape Canaveral and the Kennedy Space Center
Perhaps the author was a tourist with young children ( ? ) .
On the basis of the Box-like style of writing , were all three correspondences , from the same author ?
The Zodiac ( Nov.9th 1969 ) ; The Society for the Constitution and a Patriotic America ( Aug.23rd 1970 ) ; D B Cooper ( Dec.3rd 1971 ) .

Was the Zodiac's Exorcist Letter , his confession for having written the letters attributed to Dan Cooper ?
With the emergence of the Zodiac's Exorcist Letter , postmarked January 29th 1974 , it had been nearly three years since , officially , the Zodiac had been heard from , and over two years since Dan Cooper's skyjacking escapade on November 24th 1971 .
This is the contents of the Exorcist Letter :
I saw & think '' The Exorcist '' was the best saterical com- idy that I have ever seen . Signed , yours truley :
He plunged him self into the billowy wave and an echo arose from the suicide's grave
Ps. if I do not see this note in your paper , I will do something nasty , which you know I'm capable of doing
( THE DOODLE )
Me - 37 SFPD - 0
i ) '' He plunged himself into the billowy wave and an echo arose from the suicide's grave '' , is an extract from the Mikado's '' Willow , Titwillow ''.
A reference , perhaps , to what the Zodiac imagined had happened to Dan Cooper , when he jumped from a Jet Airliner , at 10,000 feet ( ? ) .
ii ) The doodle presented by the Zodiac , in his Exorcist Letter , can represent many different things , according to the eye of the beholder . Could the doodle represent a bird's eye view of a submarine , being attended to by tug boats and support vessels ( ? ) . There even appears to be a pontoon , with a spore and tadpole , in addition .
For this imagery , it could be the Zodiac imagining a jump from an aircraft , over San Francisco Bay . An illustrative parody , as such , of what faced Dan Cooper when he elected to escape from the Jet Airliner ( ? ) .
iii ) '' Me - 37 , SFPD - 0 '' - The official number of passengers that were subjected to the skyjacking of Dan Cooper , was 37 . Is this what the Zodiac is inferring , by '' Me - 37 '' ( ? ) . That , while he has been away from his Bay area reign of terror , the San Francisco Police Department has come up with nothing , and he , the Zodiac , is inferring that he has been terrorising elsewhere , and has 37 frightened passengers , to show for that terrorism elsewhere .
In effect , the Zodiac subliminally telegraphing his responsibility , for the letters of D B Cooper .

In the D B Cooper FBI File 22 , Pages 105-108 , there is a long-winded letter , written in hand print style , from a person that believes that they know the identity of Dan Cooper , and wants to arrange a rendez-vous , through a ( redacted ) newspaper personal ad. , in order for the person's information to be passed on , in return for a reward .
The postscript is as follows :
'' If I don't see the ad in ----- ----- on ---- I'll know you are not interested .''
Comparisons are drawn with the Exorcist Letter , from the Zodiac , whose postscript is :
'' If I don't see this note in your paper I will do something nasty.....''

A pretty postcard from the Zodiac ?
From Longview , Washington , on May 28th 1972 , a postcard which refers to the '' real live drama '' of the Dan Cooper case , and takes the time to assist the FBI by pointing the finger of guilt at a perfectly innocent motorist , with Oregon licence plates .

A typed letter with hand printed envelope , sent from Los Angeles , to the Syracuse P.D. , Syracuse , NY , dated November 18th 1975 .
A man claiming to be a believer in God , and seeing visions , fingers an employee of The Solvent and Petroleum Company of Syracuse , NY , as Dan Cooper .
In his letter , which starts : '' To whom it may concern....'' , the writer adds : '' I will not give my name because I do not want it to be in newspapers or TV .''.
This can be compared to the typed letter to Vallejo P.D.'s Detective Sergeant John Lynch , accompanying cipher keys , from '' Concerned Citizen '' , on August 10th 1969 , and believed to have been the Zodiac .
And contains the following excerpt :
'' Please forgive the absence of my signature or name , as I do not wish to have my name in the papers .''

Does lightening strike twice ?
It certainly seems to have done when , on December 31st 1979 , D B Cooper sent a typed letter to WXIA TV at 1611 West Peachtree Street , Atlanta .
The letter started :
'' Dear ----- , first let me assure you I am D B Cooper .....''
And ended :
'' I wish you a Happy New Year and thank you for this opportunity to communicate after ten years.... D B Cooper ''
Then , lo and behold , just over 14 months later , a handwritten letter postmarked March 8th 1981 .
This letter started :
'' Hello it's me ''
And signed off :
'' Zodiac ''
An infamous hijacker - Dan Cooper , and an infamous serial killer - The Zodiac Killer , both electing to write letters to the same TV Station , hundreds of miles away in Atlanta , and within 15 months of each other ?
Pretty extraordinary , unless '' D B Cooper '' and '' Zodiac '' were one and the same scribe .

On December 15th 1971 , two letters were received by the '' Oregonian '' News Paper ( sic ) , from , it would appear Colorado ( 970 ) . As the FBI suggest , from the same writer .
The first was in '' cut and paste '' form :
The Perfect Crime Grant Me Amnesty Money Will Be Returned No Harm Done Answer By Way Of Public Announcement Within 48 Hours Yabba Dabba Doo I've Won Admit You've Lost Sincerely W S.W.L Act Now ! Alais D B Cooper
Is it possible that this writer was playing an ambiguous card with two Zodiac suspects ?
i ) '' The Perfect Crime - Grant ''
ii ) '' Alais D B Cooper ''
The Perfect Crime - William Grant ( ? ) , and ALA is D B Cooper ( ? ) .
Rubislaw32: D B Cooper's coded messages to newspapers , in his '' I knew '' letter , December 11th 1971 , are solved with Rubislaw 32's Final Solution to the Zodiac's 340 Cipher . Coming soon , to this site !!

Rubislaw32: Thanks for the Blackfoot Alphabet tip , Guest 123 .This could be of interest , with the Z148 cipher text . Given a link to the Karl Werner murders , Z148 is likely to be Zodiac authentic . Nice spot .

Guest123: Most of the people murdered have double letters in their name. Is it a coincidence? Is it deliberate?
Jan 10, 2020 22:05:39 GMT -8
Guest123: Look at the Blackfoot alphabet. Some of the letters look like the symbol in one or more of the cyphers.
