SPOONERISMS AND KNIFERISMS

1/26/2025

 
Picture
When the Zodiac Killer composed his "Exorcist" letter on January 29th 1974, he was likely comparing the "satirical comedy" of "The Mikado" stage play with "The Exorcist" movie by writing "I saw + think "The Exorcist" was the best saterical comidy that I have ever seen". But did he create a "spoonerism" by switching the "i" and "e" from "satirical comedy" to play a practical joke on the audience? More accurately described as a "kniferism", he wrote "saterical comidy". A kniferism is a type of spoonerism that involves switching the vowels between words or syllables to change the meaning. By writing "signed, yours truley" and then choosing the Tit-Willow verse from "The Mikado" which contained "My name is", was the Zodiac Killer suggesting that his name could be found within the verse?

The Zodiac Killer may have noticed that "The Exorcist" movie was directed by William Friedkin, based on a novel by William Peter Blatty, and that William Shwenck Gilbert was responsible for the libretto of "The Mikado" (text of the musical work). Was this why he chose "Tit-Willow" because it contained "Will" within its text, effectively giving us "William" four times within one communication? The Zodiac Killer chose the introduction of "best saterical comidy" based upon "The Exorcist" movie winning four awards at the Golden Globe ceremony at the Beverly Hilton hotel in Beverly Hills, California on January 26th 1974,  for "Best Film", "Best Director", "Best Supporting Actress" and "Best Screenplay". Therefore, it was just coincidental that the novelist William Peter Blatty and director William Friedkin had the same forename as William Shwenck Gilbert, because he featured "The Mikado" on July 26th 1970, when he gave us more verses from the stage play. This wasn't something he could have manufactured, but it was something he could have noticed, thereby inspiring him to apply a type of "spoonerism" and altering "best satirical comedy" to "best saterical comidy" in his introduction. This may have been deliberate, because this "spoonerism" gave us our fifth William. 

Picture
William Archibald Spooner (July 22nd 1844 to August 29th 1930) was a British clergyman and long-serving Oxford don. He was most notable for his absent-mindedness, and for supposedly mixing up the syllables in a spoken phrase, with unintentionally comic effect. Such phrases became known as spoonerisms, and are often used humorously. Many spoonerisms have been invented and attributed to Spooner. William Spooner was well liked and respected, described as "an albino, small, with a pink face, poor eyesight, and a head too large for his body". It was said that "his reputation was that of a genial, kindly, hospitable man". In the opinion of Roy Harrod, Spooner exceeded all the heads of Oxford and Cambridge colleges he had known "having regard to his scholarship, devotion to duty, and wisdom".  Wikipedia.

​It would have been apt for the Zodiac Killer to use a "comedic spoonerism" when writing the 
"best saterical comidy". It may have been one big game for the Zodiac Killer, who seemingly liked taunting his pursuers with a plethora of cryptic puzzles.

"SATIRICAL OPERETTA WILL OPEN FRIDAY"

1/25/2025

 
Picture
Over the weekend of March 13th 1971 numerous calls poured into the Dublin Police Department saying they had seen the infamous Zodiac Killer, days before the Zodiac Killer's Los Angeles letter, mailed in Pleasanton, was released into the newspapers. Pleasanton borders the city of Dublin, situated 40 miles (about 50 minutes journey time by car) from San Francisco. Not only were these sightings a considerable distance from San Francisco, from where the Zodiac Killer usually mailed his letters, but these sightings and letter were 4 1/2 months removed from the last Zodiac communication. Therefore, an uptick in sightings of the Zodiac Killer, at a time and location corresponding to the mailing of a Zodiac letter, has to carry some significance. 

Just under three years later, on January 29th 1974, the Zodiac Killer yet again deviated from San Francisco by mailing a letter from either San Mateo or Santa Clara County. There is good reason why I would like to focus on the possibility that his "Exorcist" letter was mailed in Santa Clara County, in which San Jose is the county seat and largest city. 

The Exorcist letter began in mocking fashion with the writing "I saw + think "The Exorcist" was the best saterical comidy that I have ever seen". The Zodiac Killer's letter was almost certainly a reaction to "The Exorcist" film winning four awards at the Golden Globe ceremony at the Beverly Hilton hotel in Beverly Hills, California on January 26th 1974,  for "Best Film", "Best Director", "Best Supporting Actress" and "Best Screenplay". However, the Zodiac Killer didn't describe the movie as "the best comidy", he described it as "the best saterical comidy", by adding the word "satirical" into the phrase. This doesn't come as much of a surprise, because the Zodiac Killer was equating "The Exorcist" movie with the satirical comedy "The Mikado", which followed on from this introduction (by citing a Tit-Willow verse). Despite the Zodiac Killer likening these two productions through humor, they didn't comfortably sit alongside each other in one communication. 

PictureSunday Mercury News, January 13th 1974
What reminded the Zodiac Killer of "The Mikado" theater play 3 1/2 years after he had previously referenced it on July 26th 1970? Especially in a communication that capitalized on the recent release of "The Exorcist" movie on December 26th 1973. Had the Zodiac Killer attended a performance of "The Mikado" or read about one in recent weeks? Enabling him to marry the two productions together.    

​If he had, I would expect this performance to have taken place in Santa Clara County in January, to have featured prominently in the newspaper to catch the Zodiac's eye, and to have the word "satirical" front and center of the article. The following newspaper cutting is from the "Sunday Mercury News" in San Jose, Santa Clara County, advertising an upcoming production of "The Mikado" in four performances at the San Jose State University Workshop, from January 11th 1974 to January 13th 1974. Did the Zodiac Killer attend this production and mail his "Exorcist" letter from Santa Clara County, with the inserted word "satirical", to unveil his recent movements? Or at the very least, to suggest that he had recently watched the operetta at the San Jose State University? The Zodiac Killer usually composed his letters by utilizing recent newspaper articles, but was this one of them?

THE INSPIRATION FOR THE "LITTLE LIST"?

4/8/2024

 
Picture
Many Zodiac researchers have contemplated which production of The Mikado inspired the Zodiac Killer to plagiarize two acts from the Gilbert & Sullivan opera, that included "A More Humane Mikado" and "As Some Day It May Happen" on July 26th 1970. Hopefully the following presentation may help answer that question.

​Although the Zodiac Killer heavily featured The Mikado in the July 26th 1970 letter, it wasn't his first reference to the satirical play, when he wrote about Kathleen Johns two days earlier (on July 24th 1970), stating "This is the Zodiac speaking. I am rather unhappy because you people will not wear some nice (Zodiac symbol inserted) buttons. So now I have a little list, starting with that woeman + her baby that I gave a rather intersting ride for a coupple howers one evening a few months back that ended in my burning her car where I found them". The Zodiac Killer was effectively pre-empting his "Little List" letter mailed to the San Francisco Chronicle on July 26th 1970. The Bay Area murderer was often a reactive author, commenting on recent newspaper articles he had read, or something he had watched on television.

Throughout California (and other regions of America), the D'Oyly Carte 1939 production of The Mikado was featured on Channel 11 on the late night of Thursday, July 23rd 1970 and the early morning hours of Friday, July 24th 1970. That is the night before and the same day that the Zodiac Killer mailed his brief letter to the Chronicle, claiming the abduction of Kathleen Johns, and informing us that he had begun his "little list". Below are just a few examples from California.   

Picture
Curiously, but not by any means compelling, The Mikado (1939) starred Kathleen Naylor (the namesake of Johns), who joined the D'Oyly Carte Opera Company in 1933 and also played key roles in Gilbert & Sullivan's "Princess Ida" and "Iolanthe". But that isn't the interesting part of the story. Widely considered the next confirmed communication of the Zodiac Killer, the Halloween card was mailed on October 27th 1970 with the added wording of "Peek-A-Boo" and "Boo". Bearing in mind that The Mikado was a British production, "Peek-A-Boo" is usually referred to as "Peep-Bo" in the English equivalent. Kathleen Naylor played the character "Peep-Bo" in the 1939 version of The Mikado.

MY NAME IS AND ISN'T TIT-WILLOW

3/25/2024

 
PictureThe Exorcist letter. Click to enlarge
On January 29th 1974 the Zodiac Killer tempted us with his name by writing "Signed, yours truley" and then placing an extract from The Mikado's Tit-Willow verse. The implication being that the Zodiac Killer's name may be found within the verse. In 2017, I noticed that the complete Tit-Willow verse from Gilbert & Sullivan's play had the phrase "my name is" within the wording "my name isn't", reminiscent of the April 20th 1970 letter stating "This is the Zodiac speaking. By the way have you cracked the last cipher I sent you? My name is....", followed by a 13 character code.

The full Tit-Willow verse read "my name Isn't Willow, tit-willow, tit-willow", so could this have featured in the 13 character code? The Zodiac Killer could have playfully used Tit-Willow as his name on April 20th 1970, before reversing this on January 29th 1974 by invoking the Tit-Willow verse in his Exorcist letter. The proposed suggestion being "My name is only Tit-Willow". Although this solution fails by using the plaintext letters "T" and "I" to represent the ciphertext "circled 8", the three "circled 8's" can spell "TIT". One would like to believe that the Zodiac Killer - knowing his 13 character code was practically unsolvable - would have given us a clue in his later letters. So was the "Signed, yours truley" phrase, followed by "my name isn't" in 1974, that clue?

THE SUFFERING MOTHER REBORN INTO PARADISE

2/1/2024

 
PictureSan Francisco Examiner, October 4th 1964
Not convinced that a previous observation of the Adventures in Paradise television series played a role in the Zodiac Killer's choice of words in the 408 cryptogram, I began looking for more contemporary offerings from a religious aspect, in respect to the phrase "reborn in paradise". Bearing in mind that the Zodiac Killer, in two letters, paraphrased three acts from The Mikado, a comic opera set in Japan, and used Japanese style symbolism at the foot of the Exorcist letter, it had to be a possibility that "reborn in paradise" was a product of Japanese history.

If the Zodiac Killer had a leaning towards Japanese culture, was he aware of the annual Obon festival, which is observed from the 13th to the 15th day of the 7th month. However, because of differences in the solar and lunar calendar, the 7th month is either July or August. Obon is therefore celebrated at different times in different regions, on and between these dates. This can be seen in the July 26th 1969 Stockton and Evening Record newspaper shown below, where the Buddhist holiday, born from the legend of a suffering mother "reborn into paradise", was held on August 2nd and 3rd - beginning the day after the Zodiac Killer's 408 cipher carrying the phrase "reborn in paradise" arrived at three newspapers. The Zodiac Killer's 408 cipher was mailed between July 15th and August 15th 1969, with its conception likely earlier. 

Picture
Stockton and Evening Record newspaper
If the Zodiac Killer's life and/or thought processes were shaped by Japanese influences, then he would have had an interest in any newspaper or television coverage pertaining to this subject. It was previously shown how the Zodiac Killer's letters mailed on January 29th 1974, April 24th 1978 and May 2nd 1978 were heavily influenced by the Golden Globe and Academy Award ceremonies, so could the Bay Area murderer have been triggered by any recent event he had read or watched on television, that kept the phrase "reborn in paradise" in the forefront of his mind? Could he have created the 408 cipher shortly after the murders of David Faraday and Betty Lou Jensen on December 20th 1968 and added the accompanying text after his second attack on July 4th/5th 1969? On October 17th 1968, Yasunari Kawabata became the first Japanese writer to receive the Nobel Prize for Literature, before giving a Nobel lecture on December 12th 1968 entitled "Japan, the Beautiful and Myself". In part of his speech he stated "If Buddhism is divided generally into the sects that believe in salvation by faith and those that believe in salvation by one's own efforts, then of course there must be such violent utterances in Zen, which insists upon salvation by one's own efforts. On the other side, the side of salvation by faith, Shinran, the founder of the Shin sect, once said: "The good shall be reborn in paradise, and how much more shall it be so with the bad". This view of things has something in common with Ikkyu's world of the Buddha and world of the devil".

The following is taken from Palladiummag.com:: "The world of medieval Japan was one of division. The Emperor was, in practice, a distant memory; the shoguns had lost all control over their vassals. Even shrines and temples, once united in strengthening the state through prayer and ritual, now competed for believers and alms. Japan was divided against itself and circumstances forced its inhabitants to form new bonds to survive.

​Among the new alliances which this age produced were the Ikkō-ikki, a network of autonomous religious collectives that led major uprisings and controlled significant parts of Japanese society for nearly a century. Their final defeat at the hands of Japan’s warrior class set the stage both for a centralized Japanese state and the social hierarchy behind it. 
Nobunaga, head of the powerful Oda clan, conquered the capital city of Kyoto in 1568. In the years that followed, he made clear his intention to destroy the Honganji sect. The Patriarch Kennyo took him at his word and summoned all Ikkō-ikki from across the country to defend the faith with their lives. Despite graver circumstances than those faced by his predecessor Shonyo, Kennyo did not go as far as implying that those who fought for the Amida Buddha would be guaranteed rebirth in the Pure Land. Nevertheless, he threatened expulsion from the sect for those who failed to respond to the call and he did not crack down on those who raised the Ikkō-ikki’s now-famous banner of war: “Advance and be reborn in Paradise, retreat and fall immediately into Hell.”

These are just a few examples showing how a Zodiac Killer well-versed in Japanese culture could have taken "reborn in paradise" and used it in his 408 cipher on July 31st 1969, during the Obon featival that spanned this date. The religious connotations of "reborn in paradise" clearly came from somewhere - which may have subconsciously leaked into his early writings - and so reinforced the notion that The Mikado was a true passion of the Zodiac Killer.

A COMMUNICATION ALL ABOUT ME

5/16/2023

 
Picture
I would like to revisit something I've covered previously regarding the Exorcist letter mailed on January 29th 1974 and the "My Name is" letter mailed on April 20th 1970. When the Zodiac Killer designed the Exorcist letter he wrote "signed, yours truley" and then proceeded to paraphrase a verse from Tit-Willow and Gilbert & Sullivan's The Mikado. One would have thought that placing "signed, yours truley" preceding this verse was a prelude to his identity. When we visit the entirety of this act from The Mikado, it becomes apparent that the next line in the verse following what Zodiac quoted is "Now I feel just as sure as I'm sure that my name is(n't) Willow, titwillow, titwillow".

​In this instance we have a trinity of coincidences, where the Zodiac Killer tempts us with a signature from the verse, from which we can form the sentence of "my name is", that he previously used in his April 20th 1970 letter as an introduction to a mystery 13 symbol code and his name.


The Exorcist letter broke with tradition when he used "Me" instead of his crosshairs as an identity, before giving us his running victim total. Bearing in mind the aforementioned correlation between the Exorcist letter and "My Name is" letter, I couldn't help thinking his identity of "Me" would be found in the 13 symbol code using an extremely simplistic method. There is little doubt that the Zodiac Killer knew a 13 character code could not be solved using conventional techniques because of its length, so very likely created something superficial. The fact that this letter was mailed with an AM postmark on the same day the Robert Salem murder broke in the morning edition of the San Francisco Chronicle, with the Zodiac pseudonym scrawled on the wall of the victim's apartment - likely meant that this letter was prepared in haste. A code created this quickly has a high probability of being solved - a code with one repetitive feature of three circled 8's. Using the shift technique the Zodiac Killer employed in the 340 cipher, solved by David Oranchak (USA), Sam Blake (Australia) and Jarl Van Eycke (Belgium) in 2020, I used a period 8 shift in the code to select new characters 8 places to the right. 

PictureClick image to expand
Using a circular shift pattern, the first circled 8 right-shifted to the letter "M", the second circled 8 right-shifted to the letter "E", and the third circled 8 right-shifted to the Zodiac crosshairs, thereby equating the Zodiac Killer's identity to "ME", just as he had done in the Exorcist letter on January 29th 1974. Both of these correspondences tempted us with a name, both communications can be linked to The Mikado and the "my name is" phrase, and the April 20th 1970 code can easily reproduce the "Me" signature present in the Exorcist letter using the standout numerical feature in the code.

​Another communication, mailed on October 27th 1970, also featured a name synonymous with The Mikado, when the Zodiac Killer wrote *peek-a-boo you are doomed" around the knot-hole of a tree. Peek-a-boo was a character from an 1888 production of The Mikado, entitled The Capitalist. But take a look at the "ME" in the word doomed, in a card that stated "I feel it in my bones, you ache to know my name, and so I'll clue you in."

By the way, are the police having a good time with the code? If not, tell them to cheer up; when they do crack it, they will have me.

IKKŌ-IKKI - "REBORN IN PARADISE"

3/24/2023

 
PictureEdgar Allan Poe
On October 22nd 1969, the San Francisco Examiner newspaper published an article by Will Stevens, which laid down a challenge from Professor D.C.B. Marsh of the American Cryptogram Association (ACA) to the Zodiac Killer, attempting to coax him into revealing his name. The newspaper stated "Dr Marsh told the Examiner today: "The killer wouldn't dare, as he claimed in letters to the newspapers, to reveal his name in the cipher to established cryptogram experts. He knows, to quote Edgar Allan Poe, that any cipher created by man can be solved by man. Zodiac has not told the truth in his cipher messages to the Examiner, the Chronicle and the Vallejo Times-Herald. Zodiac has not done this, because to tell the complete truth in relation to his name -in cipher code - would lead to his capture. I invite Zodiac to send The American Cryptogram Association a cipher code - however complicated - which will truly and honestly include his name".

It has been proposed that Dr. Marsh was invoking the name of Edgar Allan Poe to guide the Zodiac Killer down the path of creating a code featured in one of Poe's essays or journals. Just over two weeks later, on November 8th 1969, the Zodiac Killer mailed the recently solved 340 cipher. The scytale method of decryption, that can be used to reveal the message in Zodiac's 340 cipher, was featured in the opening section of Edgar Allan Poe's essay  A Few Words on Secret Writing. The final section of the revealed message in the 340 cipher almost mirrored one of Poe's poems, The final line of the 340 cipher was probably intended to read: "I AM NOT AFRAID BECAUSE I KNOW THAT MY NEW LIFE IS DEATH. LIFE WILL BE AN EASY ONE IN PARADICE". "To One in Paradise" was written by Edgar Allan Poe. This poem was first published as part of the short story titled "The Visionary" (later retitled as "The Assignation"). The poem was also published under the names "To lanthe in Heaven" and "To One Beloved". The title "To One in Paradise" was used in the February 25, 1843 Saturday Musuem. This poem was written after the death of Poe's wife. He writes that she was his life and he lived for her and now he looks forward to the future where they will be together again in death.​ In the Zodiac Killer's 408 cipher, part of the message read: "the best part of it is that when I die I will be reborn in paradise and all the I have killed will become my slaves". The question has always been - what was the inspiration for some of the language he adopted? 

PictureBattle of Azukizaka
On of the overarching themes in the Zodiac correspondence was his plagiarized acts from The Mikado, a two-part comic opera by Gilbert and Sullivan which opened to the paying public on March 14th 1885, and was hugely successful, running for 672 performances at the Savoy Theatre in London. The Mikado is the most internationally successful Savoy opera and has been especially popular with amateur and school productions. The work has been translated into numerous languages and is one of the most frequently played musical theatre pieces in history. Setting the opera in Japan, an exotic locale far away from Britain, allowed Gilbert to satirise British politics and institutions more freely by disguising them as Japanese.

​The Zodiac would feature three acts from The Mikado in his July 26th 1970 and January 29th 1974 letters - leading many to believe the Zodiac Killer had an avid interest in the theatre, or quite possibly worked there. His Japanese style characters at the foot of the 1974 Exorcist letter could suggest an affinity to Japanese history or culture. 


Taken from Palladiummag.com: "The world of medieval Japan was one of division. The Emperor was, in practice, a distant memory; the shoguns had lost all control over their vassals. Even shrines and temples, once united in strengthening the state through prayer and ritual, now competed for believers and alms. Japan was divided against itself and circumstances forced its inhabitants to form new bonds to survive.

​
Bearing in mind the numerous plagiaristic references to The Mikado in his letters, along with the plausible connection between the afterlife poem To One in Paradise from Edgar Allan Poe and the wording chosen in the 340 cipher, was the Zodiac Killer influenced by the Japanese Ikkō-ikki’s banner of war “Advance and be reborn in Paradise" and an affinity for the country's culture and belief system, that ultimately manifested in part of his 408 cipher? Not so much a paradise lost, but a paradise found.​

THE SIGNATURE OF ZODIAC

1/9/2023

 
PictureLinda Blair as Regan
The following is an amalgamation of previous articles: 

​Six months after the Zodiac Killer's Albany, New York letter and code, another letter would arrive at the San Francisco Chronicle on January 30th 1974. Postmarked the day before (January 29th), this letter was a curious blend of The Exorcist movie (1973) and the comedic opera The Mikado (1885), two productions separated by 88 years.

The Zodiac Killer plagiarized The Mikado twice in the July 26th 1970 letter, but this appeared to have some purpose in relation to his hunting activities - that the Zodiac Killer had created a list of potential victims, who he would then kill and ultimately torture in paradise. This seemed at odds with his use of The Mikado in 1974. Any suggestion that the Zodiac Killer was contemplating suicide at this juncture because of his choice of Tit-Willow, appeared to be dashed in the following paragraph when he stated "If I do not see this note in your paper, I will do something nasty, which you know I'm capable of doing". The notion that the Zodiac Killer had reached a watershed moment and was about to ditch the pseudonym he had coveted for so many years, would also be premature, when he mailed the 1978, 1986 and 1987 letters, all containing his infamous introduction of "This is the Zodiac speaking".

​The 1978 and 1987 letters had one thing in common with the 1974 letter, in that they all carried the wording "yours truly" or "yours truley", followed by a colon. This wording is commonly used before a signature, with the colon used to separate two independent clauses when the second explains or illustrates the first. In the 1978 and 1987 letters the Zodiac Killer follows "yours truly" with "guess", whereas, he inserts the plagiarized verse from Tit-Willow where his signature should be placed in the 1974 Exorcist letter. The primary conclusion to draw from this, is the Zodiac Killer was yet again asking us to "guess" his name through the verse of Tit-Willow. 

He may have been bluffing, but giving us his first name in such cryptic fashion could never be realistically used as evidence against him, because any conclusions drawn from this verse through subjective interpretation, would never have any standing in a court of law. There are five things in relation to The Exorcist movie and the Tit-Willow verse that point to one name. There is also another that points backwards to the April 20th 1970 letter, when the Zodiac Killer teased us with his name by stating "My name is", followed by a thirteen character code. The Exorcist book was written by William Blatty in 1971, which told the story of a twelve-year-old girl possessed by a powerful demon, that was later adapted by director William Friedkin in the film version released on December 26th 1973. The Tit-Willow verse from The Mikado was created by William Schwenck Gilbert, which contained multiple examples of "Will" and "Bill" within words such as "Willo" and "Billowy" (Will and Bill being short for William). This verse followed The Exorcist introduction and the promise of a signature by use of "yours truley". If we look at the next paragraph in the Tit-Willow verse from the complete version, it reads "Now I feel just as sure as I'm sure that my name Isn't Willow, titwillow, titwillow". Very reminiscent of the "My name is" letter, but in this instance "My name Isn't". 

Now let us take a look at the final paragraph of the Exorcist letter where he wrote "If I do not see this note in your paper, I will do something nasty, which you know I'm capable of doing". This mirrors his very first communications on July 31st 1969 when he wrote "I want you to print this cipher on your frunt page by Fry Afternoon Aug 1-69, If you do not do this I will go on a kill ram page Fry night that will last the whole week end. I will cruse around and pick of all stray people or coupples that are alone then move on to kill some more untill I have killed over a dozen people". On July 31st 1969 and January 29th 1974, he concluded both correspondences with the threat "to kill" more people if his letters were not published in the newspapers. In his decoded 408 cipher, he wrote "To kill something gives me the most thrilling experence". To the best of my knowledge, this is the only time the Zodiac Killer used the word "something" prior to January 29th 1974 - and used it in reference "to kill something". So, when we look at the final paragraph of the Exorcist letter where he wrote the words "I will do something nasty", it is apparent that "to kill something" was his likely threat. The Zodiac Killer then finished the letter with another puzzle (likely decoded by Kevin Robert Brooks).

GILBERT AND SULLIVAN IN THE HALLOWEEN CARD

12/31/2022

 
If we want to discover the motivation and design of a Zodiac communication, we usually have to look no further than one or two newspaper articles precedent to the correspondence in question. Can the preceding newspaper article in the San Francisco Chronicle on October 12th 1970 tell us anything about the Halloween card mailed on October 27th 1970, including an answer to the strange symbolism depicted on the envelope address side and card inner.

The newspaper article was entitled "Gilbert and Sullivan Clue to Zodiac". Therefore, it shouldn't be any surprise that the Zodiac Killer chose a greeting card that opened with the wording "From your secret pal. I feel it in your bones, You ache to know my name, And so I'll clue you in". This was the only communication thus far that contained white text, which the Zodiac Killer adopted by adding 4-TEEN, BOO and the symbolism at the foot of the card, rather than using pasted newspaper clippings. The Zodiac Killer was very likely claiming 14 victims when he wrote this total on the skeleton's hand on the front of the card, followed by a head count of 4-TEEN above the second skeleton on the card inner, and concluding with the symbolism at foot of the card. 
Picture
The Zodiac Killer likely combined his victim count of 4-TEEN with the claimed murders of four teenagers by October 27th 1970. Having claimed the August 3rd 1969 San Jose murders of Kathie Reyne Snoozy (15) and Debra Gaye Furlong (14) in his Dripping Pen card by the addiition of "Aug" within a monthly chronological victim count, the Zodiac Killer was effectively telling us that he was incorporating 4 teenagers in his Halloween card victim count of fourteen - David Faraday, Betty Lou Jensen, Kathie Snoozy and Debra Furlong. The October 12th 1970 newspaper article stated "And he is now claiming 13 persons. Homicide detectives who've been hunting Zodiac for nearly two years frankly admit he is as much an enigma now as he was on Dec. 20, 1968, when he chalked up his first two victims. On Dec. 20, 1968, he gunned down teen-agers David Faraday and Betty Lou Jensen". The Halloween card entry of a hyphenated 4-TEEN, not only incorporated his first two victims within his total, but "chalked them up" in blackboard style writing. The Zodiac Killer had written "14" on the hand of the first skeleton, "4-TEEN" over the skull of the second skeleton, so it could be argued that the symbolism at the foot of the card containing what appeared to be a joined "F", was likely "fourteen" as well  The symbolism could represent "Zodiac Fourteen" or "Zodiac Victims Fourteen" (with the four dots representing the four teenagers, just as he had incorporated them by separating "4" and "TEEN" earlier). His victim totals all neatly chalked up within the Halloween card.
Picture
The vast majority of the newspaper article was dedicated to the two act comic opera, The Mikado, and the search for individuals who may have played Ko-Ko in recent years, Many Zodiac researchers have considered whether the Zodiac Killer was of British origin, had British parents, or was influenced by British theatrical plays, based upon the language he adopted in his communications. It is extremely likely that the Zodiac Killer chose to write PEEK-A-BOO around the knothole of a tree because he knew the alternative British term for this saying.

​"Peekaboo (also spelled peek-a-boo) is a form of play played with an infant. To play, one player hides their face, pops back into the view of the other, and says Peekaboo!, sometimes followed by I see you!  There are many variations: for example, where trees are involved, "Hiding behind that tree!" is sometimes added. Another variation involves saying "Where's the baby?" while the face is covered and "There's the baby!" when uncovering the face". Wikipedia. A British term for "peek-a-boo" is "peep-bo" - which just happens to be one of the characters from The Mikado.

​The Zodiac Killer chose the introduction on the Halloween card outer in response to the newspaper article entitled 
"Gilbert and Sullivan Clue to Zodiac", because it stated "And so I'll clue you in". He then responded to this introduction by inserting "peek-a-boo" around the knothole of a tree, with an eye peering from within. A saying which has the alternative of peep-bo - a character from the Gilbert and Sullivan opera. The teaser of "I'll clue you in" and the answer of "peep-bo" both inspired by The Mikado featured in the October 12th 1970 newspaper article. The Zodiac Killer would not give us the Ko-Ko investigators were desperately attempting to track down, only the protector or ward of Ko-Ko.

ROBERT SALEM-THE COMPLETE STORY

An amalgamation of articles: 
LATEST UPDATE, INCLUDING POLICE REPORTS & PHOTOGRAPHS

Sergeant John Lynch of the Vallejo Police Department received a typewritten card from a "concerned citizen" on August 10th 1969 stating "Dear Sergeant Lynch. I hope the enclosed "key" will prove to be beneficial to you in connection with the cipher letter writer. Working puzzles criptograms and word puzzles is one of my pleasures. Please forgive the absence of my signature or name as I do not wish to have my name in the papers and it could be mentiond by a slip of the tongue. With best wishes. concerned citizen". It also contained a working key to the 408 cipher, which was mailed by the Zodiac Killer in his three "code letters" to the Vallejo Times-Herald, San Francisco Chronicle and San Francisco Examiner on July 31st 1969. On October 7th 1969, another concerned citizen, this time describing himself as a "good citizen", mailed another cryptic message to Sergeant John Lynch, stating "On occasion, while thinking of the code letters, the pencil wrote:Go to 56 Beach Street. I get the name Jerry, perhaps he knows people or his name is XXXXXXX". The author by mentioning "code letters" is clearly referring to the trinity of communications mailed on July 31st 1969, to which the August 10th 1969 communication provided a key. Despite both the "concerned citizen" and "good citizen" communications being extremely brief in nature, both utilized the word "name" twice. The author of these two communications can be argued to be the Zodiac Killer, who also mailed the April 20th 1970 letter, teasing us with "my name is". Crucially, the "concerned citizen" card and code key had not been released into the public domain by the arrival of the "good citizen" letter.  

Recently I have been examining the murder of Robert Michael Salem who was found stabbed in his 745 Stevenson Street, San Francisco apartment on April 19th 1970. The April 20th 1970 Zodiac Killer letter was received at the San Francisco Chronicle the same day the Robert Salem murder was reported in their newspaper. The letter read "This is the Zodiac speaking. By the way have you cracked the last cipher I sent you? My name is", belatedly followed by "I hope you have fun trying to fiygure out who I killed". The Zodiac Killer chose three Christian symbols in his enclosed 13 character code that mirrored the Christian symbolism written in blood on the apartment wall of Robert Salem. Above the Japanese tatami mat where Robert Salem's body lay was the drawing of an Egyptian ankh or "crucified man", along with the wording "Satan Saves" and "Zodiac". The murder of Robert Salem and the April 20th 1970 letter so reeked of Christian symbolism that it was hard to ignore that the two weren't connected, and led me to believe that the wording "Satan Saves" had some biblical meaning with respect to Robert Salem and his homosexual lifestyle. Whether the drawing of the Egyptian ankh or "crucified man" on the wall of Robert Salem were interchangeable in the mind of the killer is unknown, but the San Francisco Chronicle on April 20th 1970 made no mention of the Egyptian ankh - making the appearance of the Christian anchor in Zodiac's 13-Symbol cipher intriguing. Anchor and ankh have the same phonetic root - and when the Zodiac Killer's crude anchor in the code is superimposed over the ankh drawing on Robert Salem's wall - a full and complete Christian anchor is revealed.   .
Picture
The ankh (key of life) was commonly held in the hands of ancient Egyptian deities, or being given by them to the pharaoh, to represent their power to sustain life and to revive human souls in the afterlife. The ankh was one of the most common decorative motifs in ancient Egypt and was also used decoratively by neighbouring cultures. Coptic Christians adapted it into the crux ansata, a shape with a circular rather than oval loop (as seen in the image above), and used it as a variant of the Christian cross. The message of "Satan Saves" rather than "Jesus Saves", along with a crucifix style cross, gives the strong impression of a murder with religious connotations, bearing in mind the anti-gay and intolerant Christian attitudes that permeated society in 1970 (and to a lesser extent today). Robert Salem was a gay man who may have unfortunately attracted somebody with the belief he was a sinner or non-believer - and hence the sarcastic message of "Satan Saves" and the "key of life" being drawn on his stomach. Clearly, the person who drew the symbol and writing, was portraying a message to the viewer (whether a belief sincerely held or not).

The most unusual and notable features inflicted to the body of Robert Salem were the crucifix style design "drawn" on his stomach and the removal of his left ear. Both of these featured heavily in the crucifixion of Jesus. Simon Peter, a disciple of Jesus, attempted to "save" and protect Jesus from arrest by severing the ear of Malchus, who was a servant of the Jewish High Priest Caiaphas. According to the gospels, Calaphas organized a plot to kill Jesus. The arrest of Jesus was a pivotal event in Christianity recorded in the canonical gospels. It occurred shortly after the Last Supper (during which Jesus gave his final sermon), and immediately after the kiss of Judas, which is traditionally said to have been an act of betrayal since Judas made a deal with the chief priests to arrest Jesus. This event ultimately led, in the Gospel accounts, to the crucifixion of Jesus. Although the right ear of Malchus was severed as opposed to the left ear of Robert Salem, this was the most viable connection I could find that links the two unusual features discovered by investigators on the body of Robert Salem.​
Picture
The immediate murder with a Zodiac connection after the "latent homosexual" suggestion was floated in the San Francisco Chronicle, where the Bay Area murderer's pseudonym was found at the crime scene, was the murder of gay man, Robert Salem on April 15th 1970 in San Francisco. The Zodiac Killer's 13-Symbol cipher is arguably contemporary in nature, with his April 20th 1970 letter being mailed the same day this murder was published in the newspapers. Homosexuality and acceptance has been a continuing struggle for gay activists to this day, but the 1960s and 1970s were arguably more difficult times with newspaper coverage on this topic less than acceptable. Many religious people were unwilling to accept individual rights, claiming that homosexuality was the mark of the beast and an abomination in the eyes of God. The writing in blood on Robert Salem's apartment wall stating "Satan Saves" must have had some meaning to the killer - so was it in any way connected to the sexual preferences of Robert Salem? I couldn't help thinking that the "Satan Saves" element written in blood on the apartment wall had a more important role to play, not only in the fact Robert Salem was homosexual, but in the damage inflicted to his body and the removal of his left ear. So I looked for a bible verse that may have been known to the killer. 

​I also had to be mindful that the bible verse was relevant to perceived "sins of the flesh". In other words, the murderer of Robert Salem had an issue with homosexuality and believed it to be satanic, wanting to deliver him unto Satan to be saved (see image above). Hence the wording "Satan Saves". 1 Corinthians 5:5 featured Paul, who had commanded the Christians in Corinth to remove from among them a man who was sleeping with his father's wife, a form of sexual immorality that even their own pagan culture condemned. The killer of Robert Salem may have considered his lifestyle the devil's work and a form of sexual immorality that resulted in "destruction of the flesh" as witnessed by investigators at the crime scene. I also took the "Satan" element from the apartment wall and combined it with the "destruction of the flesh" to create a relevant solution to the 13-Symbol cipher of "Skin A Satanist". Not only did the Zodiac Killer encipher the word "skin" twice in the 148 character cipher in 1971, but it was relevant to the Robert Salem crime scene in April 1970.

Picture
Robert Michael Salem was found murdered in his 745 Stevenson Street San Francisco apartment on April 19th 1970, accompanied by the drawing of a religious crux ansata (crucified man) and the words "Satan Saves" scrawled in blood on the wall. This somewhat mirrored the religious characters in the 13 character code mailed by the Zodiac Killer the following day (April 20th 1970), when he posed the question "I hope you have fun trying to fiygure out who I killed". Investigators found no forced entry at Robert Salem's apartment, and little appeared to have been taken from the property other than possibly some money from an open wallet on a shelf. The crime scene appeared to scream of far more than a simple robbery. This opens up the possibility that Robert Salem was murdered by somebody known to him, or somebody that befriended him with common interests. Robert Salem was a lamp designer whose products had been exhibited in Japan, England and Russia. His apartment certainly showed an Oriental influence, with a Japanese hurricane lamp hanging from the ceiling, tree trunks prominent in the apartment in the style of Japanese tea houses, and he was discovered murdered wearing Oriental lounging clothes on top of a Japanese tatami mat.

Three months after this crime, the Zodiac Killer mailed the Little List letter on July 26th 1970 paraphrasing two acts from The Mikado, a Gilbert & Sullivan comic opera set in Japan. The first act he paraphrased was entitled A More Humane Mikado, followed by As Some Day It May Happen, in which victims or society offenders must be found and who would never be missed. His introduction in the communication detailed how he would torture his victims in paradise, stating in one part: "Others I shall skin them alive + let them run around screaming". In the middle of 1971 the Zodiac Killer would again mention the skinning of victims, when he encrypted the following in his 148 character cipher: "If this is not on the front page in a week I will skin 3 little kids and make a suit from the skin", and wrote in accompaniment to the cipher "Next time I will send a patch of human skin". This is why I found the phrase "Skin A Satanist" very interesting, when from a cryptology standpoint it satisfied the 13 character code on April 20th 1970, arriving the same day the Robert Salem story broke in the San Francisco Chronicle detailing the "Satan Saves" on the apartment wall. Robert Salem was effectively skinned, when his left ear was severed and taken from the crime scene. On January 29th 1974 the Zodiac Killer would again recite a section from The Mikado using a verse from Tit-Willow. Not only did he paraphrase the Japanese based opera, but he added some Oriental characters at the foot of the letter. One line in this act reminded me of the introduction in the April 20th 1970 (My Name Is letter). It read "Now I feel just as sure as I'm sure that my name Isn't Willow, titwillow, titwillow", 

Robert Salem was a flamboyant character with an interest in the arts, having been the lighting designer for the historic Haslett Warehouse at 680 Beach Street, San Francisco in 1969. Other than the mention of Washington and Maple streets on October 13th 1969, the only other street the Zodiac Killer ever imentioned in his communications (if authentic} was when he mailed a letter to Sergeant John Lynch on October 7th 1969, when he wrote ''Go to 56 Beach Street. I get the name Jerry, perhaps he knows people or his name is XXXXXXX''. So, was the Zodiac Killer in the apartment of Robert Salem in April 1970?​​​

​​Cragle, an excellent Zodiac researcher who contributes to both forums, sent Michael Morford some invaluable information that he knew I would like (and Mike subsequently added some extra findings). It was fantastic news. A letter was possibly mailed by the Zodiac Killer on October 7th 1969, containing the wording ''Go to 56 Beach Street. I get the name Jerry, perhaps he knows people or his name is XXXXXXX'' (and mentioned code letters). This letter can now be inextricably linked to the Concerned Citizen card postmarked August 10th 1969, which gave us a key to the 408 cipher, mailed by the Zodiac Killer within three "code letters" on July 31st 1969. The 56 Beach Street address never existed in 1969, except for on street planning maps. Cragle found a Carl John Welz (married to Jerry Hatcher) who were working at 680 Beach Street, San Francisco and living at 2529 Union Street, San Francisco in 1969, He had a Batchelor and Master of Arts, taught in many public and  private schools and was well known in Christian science circles with a mentioned periodical from him in 1967 (see below).

If this was the "Jerry" a possible Zodiac Killer was referring to, then this is an enormous find, Carl John Welz (and wife) would most likely have been working at 680 Beach Street at the same time as Robert Michael Salem, who was murdered by somebody claiming to be the Zodiac Killer on April 15th 1970. Throughout 1969, Robert Salem worked as the lighting designer for the historic Haslett Warehouse at 680 Beach Street. Carl John Welz wrote an anti gay article entitled Homosexuality Can Be Healed, so the fact that murdered Robert Salem was a homosexual with the wording "Satan Saves" and a "crucified man" drawn in blood on his apartment wall, with the pseudonym Zodiac present also, makes this is a significant find. We can now connect the August 10th and October 7th 1969 communications, link the name "Jerry" to the Haslett Warehouse at 680 Beach Street, and to murder victim Robert Salem, who also worked there - and finally - combine the religious overtones from the above article to the apartment wall, and to the Zodiac Killer's 13-Symbol cipher..

Question marks have always hung over the October 5th 1970 13-Hole Postcard as to whether the author was the Zodiac Killer or a copycat. This article will hopefully go a long way to convince people that the communication was indeed mailed by the Bay Area murderer. The Zodiac Killer wrote the lengthy Little List Letter on July 26th 1970, beginning the correspondence with his intentions for his slaves in paradise, followed by the torture methods he was going to apply, before finishing with the plagiarism of Gilbert & Sullivan's The Mikado, from the Act As Some Day it May Happen. The crucial thing to remember here, is that the Little List Letter was withheld from the newspapers and public alike, so by October 5th 1970 when this postcard was mailed, the author (if not Zodiac} was totally unaware to the contents of the Little List Letter. It is possible that the Zodiac Killer could have been reemphasizing his victim total of thirteen after his previous letter was unpublished, or a copycat could have been suggesting thirteen victims for the first time, unaware that the Little List Letter had ever been mailed. Therefore, this is no help in determining whether the author of the 13-Hole Postcard was the Zodiac Killer or not. We need to look at the wording on both communications back to back.

The first thing to notice on the 13-Hole Postcard is the crucifix and number 13 in close alliance - extremely relevant when we consider the Zodiac Killer using the phrase "I shall (on top of everything else) torture all 13 of my slaves that I have waiting for me in Paradice" in the Little List Letter. The crucifix, a symbol of Christianity and the progression from life on earth to the paradise of heaven, is further cemented by the October 27th 1970 Halloween Card where the Zodiac Killer actually combines all three elements. However, if you are also a skeptic of the Halloween Card, then we need to focus entirely on finding a link between the 13-Hole Postcard and the previously unpublished Little List Letter, both eventually released in tandem with one another on October 12th 1970 in a newspaper article by Paul Avery. Below I have separated the Little List Letter into its constituent parts - his promise of torture, his methods of torture and the search for victims.            

Picture
[1] This is the Zodiac speaking. Being that you will not wear some nice buttons, how about wearing some nasty buttons. Or any kind of buttons that you can think up. If you do not wear any type of buttons, I shall (on top of everything else) torture all 13 of my slaves that I have waiting for me in Paradice.

[2] Some I shall tie over ant hills and watch them scream + twich and sqwirm. Others shall have pine splinters driven under their nails + then burned. Others shall be placed in cages + fed salt beef untill they are gorged then I shall listen to their pleass for water and I shall laugh at them. Others will hang by their thumbs + burn in the sun then I will rub them down with deep heat to warm them up. Others I shall skin them alive + let them run around screaming. And all billiard players I shall have them play in a darkened dungen cell with crooked cues + Twisted Shoes. Yes I shall have great fun inflicting the most delicious of pain to my slaves.


The Mikado/Act I/Part Va - As Some Day it May Happen
[3] As some day it may hapen that a victom must be found. I've got a little list. I've got a little list, of society offenders who might well be underground who would never be missed who would never be missed.

PictureArthur Sullivan
The Zodiac Killer refers to his victims in the plural and in the future tense, beginning his torture methods with "Some I shall tie over ant hills and watch them scream + twich and sqwirm. Others shall have pine splinters driven under their nails + then burned. Others shall be placed in cages + fed salt beef untill they are gorged then I shall listen to their pleass for water and I shall laugh at them". He uses the word "some" to begin his rhetoric, then continues with his Little List of potential victims, sourced from As Some Day it May Happen, beginning with "As some day it may hapen that a victom must be found". Therefore, is it any great surprise that the Zodiac Killer having noted his lengthy communication was not published in the newspapers, would begin the 13-Hole Postcard in the past tense, stating "The pace isn't any slower. In fact it's just one big thirteenth. Some of them fought it was horrible". The last sentence likely referring to the slaves he previously mentioned he was going to torture. 

The Zodiac Killer is effectively saying that he had now tortured his victims in paradice and "some of them had fought". He is telling Paul Avery and the San Francisco Chronicle newspaper he had made good on his promises. This strongly suggests that the author of the 13-Hole Postcard knew the contents of the July 26th 1970 Little List Letter, thereby cementing the notion that the Zodiac Killer was the author of both communications. The alternative, is that a copycat just threw together a random postcard that not only continued the theme of the previous letter accidentally, but was adopted by the Zodiac Killer in the October 27th 1970 Halloween Card and the following March 13th 1971 letter, where the Zodiac Killer stated "
This is the Zodiac speaking Like I have allways said, I am crack proof". The copycat scenario proliferated by many, a sensational subplot to discredit certain Zodiac communications and attacks, where no merit for such claims exist. 

The other notable element of the 13-Hole Postcard is the Mon, Oct 5, 1970 attribution in the top right corner. The Zodiac Killer did recite the Gilbert & Sullivan Act
As Some Day it May Happen. So was Monday, October 5th the day something happened - and the reason he added a specific date for the very first time?

A THEATRICAL ILLUSION

4/1/2019

 
Alan Keel, Criminalist at the San Francisco Police Department, San Francisco, California from 1996 to 1999 "revealed that there were two letters in possession of the department that, in contrast to the "true" Zodiac letters, had abundant saliva and DNA-containing oral epithelial cells on them, that DNA was easily extracted from these two letters, and that the DNA extracted from these two letters matched between them. These two letters were considered forgeries, since the "true" Zodiac verifiable letters had not been licked by the sender". Mike Rodelli, an avid Zodiac researcher, who conversed with Alan Keel, revealed "In contrast (to earlier communications), Keel analyzes two other letters, one of which is the 1978 forgery, and finds that this letter and one of the 1974 letters are loaded with saliva and cells. He then easily extracts DNA from both of these letters using the more primitive DNA technology of that time and finds that the DNA matches between those two letters, thus proving that one person sent both".  Mike Rodelli.

​
If you take a look at the San Francisco Police Department DNA report, the 1974 Exorcist letter is the only letter that year to produce any viable results, described as "cells found". The S.L.A letter was totally disregarded, and the "Citizen" and "Red Phantom" communications had no entry in comments. If Alan Keel is correct in his assertion, then the Exorcist letter would enter the classification of unlikely Zodiac correspondences - ones that had "been licked by the sender". 
Picture
In the latest round of DNA testing in the Zodiac case, two of the three July 31st 1969 communications have again come under scrutiny. These were unavailable at the time the San Francisco Police Department DNA testing was undertaken. It is apparent that these letters have struggled to give up their secrets, as have other communications listed in the report, which includes the October 13th 1969 'Paul Stine' letter, the November 8th 1969  'Dripping Pen' card, the November 9th 1969 'Bus Bomb' letter, the December 20th 1969 'Melvin Belli' letter, the April 20th 1970 'My Name Is' letter, the April 28th 1970 'Dragon' card and the June 26th 1970 'Button' letter. In total, nine consecutive communications that, it is fair to say, have produced little in the way of a recognizable DNA fingerprint. Most of these are labelled in comments as "few cells".

The only remaining communications in the DNA report subsequent to June 26th 1970 which produced any notable results, classified as "cells found", were:
[1] The July 24th 1970 'Kathleen Johns' letter.
[2] The July 26th 1970 'Little List' letter, and
[3] The January 29th 1974 'Exorcist' letter.
And all three had one crucial element in common - The Mikado. 

The 'Kathleen Johns' letter began the trilogy by stating "So now I have a little list, starting with that woeman + her baby that I gave a rather intersting ride for a coupple howers one evening a few months back that ended in my burning her car where I found them".  This would be continued two days later with the paraphrasing of two of Gilbert and Sullivan's acts from The Mikado. The first section of the 'Little List' letter pulls lines from the A more humane Mikado, where the author uses the words billiard along with crooked cues and twisted shoes.
This correspondence goes on to paraphrase Gilbert and Sullivan's  As some day it may happen, performed by Ko-Ko, as did the future correspondence of the Exorcist Letter in 1974, when reciting Tit-Willow from Ko-Ko's On a tree by a river, part of Act Two.  

We don't know the exact concentrations of DNA retrieved from these three communications, but it is evident that these were the only three letters classified as "cells found" - and all three made reference to The Mikado. If "cells found" could be proven as "saliva" found, and the "true Zodiac verifiable letters had not been licked by the sender" according to Alan Keel, then this could indicate that all The Mikado letters were not authored by the Zodiac Killer. An extremely hard notion to accept when we look at the handwriting and design of each of these correspondences. 

Picture
One can understand why certain sections of the Zodiac communications were withheld from the public, such as his bomb diagrams - yet the entire July 26th 1970 'Little List' letter was not released to the newspapers until October 12th 1970. This innocuous correspondence for the most part was withheld for two and a half months until it featured in a San Francisco Chronicle article entitled 'Gilbert and Sullivan Clue to Zodiac', in tandem with the subsequent October 5th 1970 '13 Hole' postcard. If the 'Little List' letter and '13 Hole' postcard were authored by the Zodiac Killer, then it is notable that, despite putting a lot of effort into this rather lengthy correspondence on July 26th 1970, he failed to make any issue about the complete absence of newspaper coverage that this letter received when he mailed his next correspondence. It is believed he repeated his victim count of 13 because his last letter hadn't been published in the newspapers. But could it have been the case that the Zodiac Killer wasn't reaffirming the victim count of 13 because his previous correspondence wasn't published, rather, he was unaware somebody had mailed the 'Little List' letter in his name? Hence his lack of concern about "front page coverage", or for that matter, any coverage at all. 

If the Zodiac Killer hadn't written any of The Mikado communications, then he also wasn't claiming the abduction of Kathleen Johns on March 22nd 1970. In fact, the notion of a killer driven by the theatrical librettos of Sir William Schwenck Gilbert would be quashed entirely. It is extremely difficult to sell a story of a Zodiac Killer who didn't author any of The Mikado communications, let alone all of the 1974 communications - so the curtain call will be cancelled for this performance only. 

WILL-I-AM THE MURDERER

2/5/2019

 
The following is highly speculative and not intended as a solution to the identity of the Zodiac Killer, moreover, an exploration of the January 29th 1974 Exorcist letter in which the author wrote the tantalizing words "Signed, yours truley". Usually the word "signed" would be followed by an author's name, either in full or part. The author of the Exorcist letter stated "Signed, yours truley: He plunged himself into the billowy wave and an echo arose from the suicides grave, titwillo, titwillo, titwillo".

The designer of the Exorcist letter was seemingly substituting the signature with a verse from The Mikado's Tit-Willow. In other words, it could suggest his name is present somewhere within the verse. The Zodiac Killer (if the author) chose a verse not in keeping with his two previous Mikado selections,  As some day it may happen and A more humane Mikado - both of which had threatening overtones of torture and murder. Whereas, Tit-Willow is about a little tom-tit's last reflective moments before his suicidal plunge into a billowy wave. This may suggest the verse Tit-Willow was chosen for an entirely different reason, particularly in view of the preceding line of "Signed, yours truley" notable on the Dear Boss letter signed by Jack the Ripper and postmarked September 27th 1988, just three years after The Mikado opened at the Savoy Theatre. It should also be noted that William S. Gilbert, responsible for the libretto of The Mikado, released Songs of a Savoyard in 1890 featuring many of the songs from their comic operas. Six songs from The Mikado can be found in Songs of a Savoyard, three of which Zodiac chose - assuming of course, Zodiac was responsible for the January 1974 offering.

Did the Zodiac Killer embed his name somewhere in his communications as he had promised in his later correspondence? - giving away his forename would certainly not lead to his capture. It has been speculated that the Exorcist letter was a contemplation of suicide on behalf of the author, however, this is hardly in keeping with the threatening overtones of the Bay Area murderer and certainly out of kilter with the foot of the Exorcist letter which threatens to "do something nasty, which you know I'm capable of doing". It gives the impression that he is threatening to take somebody else's life, not his own. 

There is a strange dichotomy evidenced in the letter, where the author begins by referencing 'The Exorcist' movie (1973) and immediately follows it up by paraphrasing 'Tit-Willow' from 'The Mikado' (1885). 'The Mikado' is often described as the best in British satire, as well as a comedy opera, therefore the word usage of the author describing it as a 'satirical comedy' is unlikely to be accidental. Additionally, the attempted blending of these vastly different productions into one correspondence seems forced, as if chosen for a specific purpose.

The libretto or text was plagiarized from William S. Gilbert. The Exorcist is an  American horror film released in 1973, directed by 
William Friedkin and adapted for screenplay by William Peter Blatty, based on his 1971 book. The movie divided audiences and critics alike, as it explored the subject of demonic possession, in this case, that of a 12-year-old girl played by Linda Denise Blair. This masterpiece of evil still remains one of the most iconic movies in the horror genre to this day. It is fairly evident that the three main protagonists in these productions all have the forename "William". It is also apparent that every verse of Tit-Willow  ends with "Oh, willow, titwillow, titwillow!", in which the name "Will" can be observed three times. The shortened version of William is also present in "billowy". Did the Zodiac Killer choose the Tit-Willow verse after "Signed, yours truley" for no other reason than it contained his name embedded in the text? The next line after "Oh, willow, titwillow, titwillow!" is "Now I feel just as sure as I'm sure that my name".

Bearing in mind the estimated age of the Zodiac given as between 25-45 in 1969, this would make his birth date between 1924 and 1944. So, from a statistical standpoint, I looked at the most popular boys names in the USA in the 1920s, 1930s and 1940s. William was ranked 4th highest in the 1920s with 512,400, 4th highest in the 1930s with 416,646 and 4th highest in the 1940s with 556,399.

In the April 20th 1970 '13 Symbol' cipher, Zodiac stated "This is the Zodiac speaking. By the way have you cracked the last cipher I sent you. My name is...."  The cipher contained three characters twice (A, N, and M) and one character three times (joined O and 8). Therefore, the name "William" gives us a good starting point with two repeating letters.

As an experiment, I looked at the most popular American surnames that could possibly fit the criteria required by the '13 Symbol' cipher and the already inserted "William". Sixteenth on the list was the name Martin, giving us an estimated name of William Martin for the Zodiac Killer. There are many alternative second names that could be applied, but if "William" was the responsible's forename, we would be looking for a 6-letter surname for the confirmed murderer of five.

THE ARRIVAL OF THE EXECUTIONER

11/20/2018

 
The Exorcist letter has recently come under the spotlight regarding its authenticity as a Zodiac communication, but regardless, we will examine it in context to previous correspondence from the Bay Area murderer and hopefully show that the entire letter is designed around the Gilbert & Sullivan comedic opera 'The Mikado', in particular Ko-Ko the Lord High Executioner. The Zodiac Killer had now seemingly dropped his long-held pseudonym after a three year hiatus and had reemerged, vowing to continue his campaign of murder under a new guise.    
PictureClick to enlarge letter
The Zodiac Killer had previously used two musical numbers from The Mikado when he mailed the Little List letter on July 26th 1970. The first was 'A More Humane Mikado', followed by 'As Some Day It May Happen', featuring Ko-Ko, the Lord High Executioner.​ This was noted in the San Francisco Chronicle on October 12th 1970, just 15 days prior to the mailing of the 'Halloween' card: "It was immediately apparent that Zodiac had plagiarized several stanzas from an aria in the Gilbert and Sullivan operetta 'The Mikado'. It is the entrance aria of Ko-Ko, the Lord High Executioner. A quiet search of onetime Ko-Ko's has turned up none that could be Zodiac. Obvious differences in physical description and handwriting comparisons have cleared all Ko-Ko's tracked down since the arrival of the July 27 letters."

The text on the Exorcist letter is split into three sections: [1] The introduction referring to the recently released Exorcist movie, and featured in a newspaper article by reporter Paul Avery, [2] The latest Zodiac pseudonym disguised under the heading of 'Yours truley', and [3] The customary threat promising more victims if his "note" is not published.

There is little doubt that the Zodiac Killer (now Lord High Executioner) is describing the William Friedkin movie 'The Exorcist' in terms of 'The Mikado'. The Gilbert & Sullivan play is often described as a comedic opera of political satire, so the author choosing the words "I saw and think "The Exorcist" was the best satirical comedy that I have ever seen" is certainly not by accident. However, it is the introduction of "I saw and think" that may carry more meaning than initially thought.
​
'As Some Day It May Happen' featured heavily in the July 26th 1970 letter. It was spoken by Ko-Ko, the Lord High Executioner, with the word "think" appearing four times during this act, including the introduction :
[1] "Gentlemen, I'm much touched by this reception. I can only trust that by strict attention to duty I shall ensure a continuance of those favours which it will ever be my study to deserve. If I should ever be called upon to act professionally, I am happy to think that there will be no difficulty in finding plenty of people whose loss will be a distinct gain to society at large". [2] and [3] "And who doesn't think she dances, but would rather like to try; And that singular anomaly, the lady novelist — I don't think she'd be missed — I'm sure she'd not be missed". 
[4] "He's got her on the list — he's got her on the list; And I don't think she'll be missed — I'm sure she'll not be missed".

PictureGroucho Marx as Ko-Ko (1960)
Was the Zodiac Killer reprising his performance of the Little List letter and using the introduction of "I saw and think" under the guise of Ko-Ko, the Lord High Executioner?  This argument may be bolstered, when he immediately follows this up by signing his new pseudonym in the form of another Ko-Ko, Lord High Executioner verse from 'On A Tree By A River' featuring tit-willow. The author is simply saying "Signed, yours truley: The Lord High Executioner." 

The third section of text on the 'Exorcist' letter is uncannily similar to the first letters mailed by the Zodiac Killer on July 31st 1969. The 'Exorcist' letter was mailed to the San Francisco Chronicle, so we will take a look at the July 31st 1969 letter mailed to the same paper. This is what the killer signed off with: "I want you to print this cipher on the front page of your paper. In this cipher is my idenity. If you do not print this cipher by the afternoon of Fry.1st of Aug 69, I will go on a kill ram-Page Fry. night. I will cruse around all weekend killing lone people in the night then move on to kill again, until I end up with a dozen people over the weekend." It begins with a demand to print his material in the paper, and finishes with the threat "to kill" again if his instructions are not followed, exactly like the Exorcist letter. 

The 'Exorcist' letter symbols were decoded by Kevin Robert Brooks to spell the words "To Kill", which although not proven, makes perfect sense with respect to the July 31st 1969 letters, and in keeping with the Lord High Executioner's list of people who will not be missed. The Mikado style symbolism at the foot of the Exorcist letter threatening "To Kill" again, lending credence to the notion the Zodiac Killer is now operating under the pseudonym of a Japanese High Executioner. 

The answer that has always eluded people - is did the Zodiac Killer begin his murders and letter writing in Riverside, before resuming his campaign of terror in the Bay Area? The Zodiac Killer communications began on July 31st 1969, and presumably ceased with the last confirmed correspondence on January 29th 1974. We have shown the similarity of threats exhibited by the Exorcist letter and the trinity of July 31st 1969 letters, regarding his promise "to kill" if his cipher or "Tit-willow" communications were not published. The 408 cipher was split into three parts (similar to the Exorcist letter) containing 8 lines of text, thereby 24 lines in total. The verse Tit-willow was split identically to the 408 cipher, three verses of 8 lines. The three Bates letters were mailed to Joseph Bates, the Riverside Press Enterprise and Riverside Police, and once again contained double postage like much of the Zodiac correspondence, with each containing just 8 words: "Bates/She had to die there will be more".   

The Mikado influence is present in all three sections of the Exorcist letter (including the Asian style characters) in a reinvention of the July 26th 1970 Little List letter. Was the Exorcist letter a hoaxer operating under the guise of the Zodiac Killer, plagiarizing the Gilbert & Sullivan opera once again and convincing us the threat was still alive in the Bay Area after nearly five years, or was the executioner at Lake Berryessa on September 27th 1969 biding his time, before extinguishing the Zodiac Killer once and for all?
