We are coming towards the end of the series of articles examining the 1974 letters. This article will be a continuation of 'The Hearst Family Connection' with one final piece of the jigsaw regarding the May 8th 1974 Citizen card to look at. Here is a brief recap of the previous article: "This all began on February 3rd 1974 with the S.L.A letter, postmarked "U.S. Postal Service, CA 913 PM 3 FEB 1974". This was the eve of the kidnapping of Patricia Campbell Hearst, which occurred on February 4th 1974. The letter signed off with "a friend". On February 10th 1974, a Symbionese Liberation Army member mailed a typed letter to the Hearst family at 233 W. Santa Inez Ave, Hillsborough, California, postmarked "U.S. Postal Service, CA 940 PM 10 FEB 1974". It too was signed off with "A friend". 

​The article argued that the Citizen card had been targeted at William Randolph Hearst Sr, who had previously forbade his newspapers running any ads for the Orson Welles Citizen Kane movie, released in Los Angeles on May 8th 1941. Hence the context of the card and the signing off with "A citizen". 

The day after the Symbionese Liberation Army mailed the February 10th 1974 typed communication to the Hearst family, another typed communication arrived stating:
Hearst Family, 
(Second Commandment: "For I the Lord as a jealous God and visit the sins of the fathers upon the children unto the third and fourth generation.)
No, we are not religious nuts, but we hate you for your father's part in starting the Spanish-American War, and also for his later, cheap liason with the trollop Marion Davies."
Our male ancestors were killed in your father's war and their wives were left with pensions of $25 to $50 a month for life. We wonder how you can hold up your heads in decent society, and why your contemporaries can stomach your presence. Our once proud families were destroyed by your father's war.....which he started to boost his circulation 
                                     HERE IS WHAT WE DEMAND;
Before we release your daughter Patricia, you must show proper humility by acknowledging the guilt of William Randolph Hearst (in regard to starting yellow journalism and instigating the Spanish-American War. You must publicly beg the forgiveness of your country. This must be done on ALL media and must be expressed in terms of abject humility.
When we are convinced you are showing abject humility for the sins of your father and his papers, we will release Patricia, whose only sin is that she carries the genes of William Randolph Hearst.
                                                                                        The SLA   

The February 11th 1974 Hearst letter focused on the "yellow journalism" employed by William Randolph Hearst regarding the Spanish-American War and called for his forgiveness to be "expressed with abject humility". The following purported Zodiac communication on May 8th 1974 "expressed consternation at the lack of concern for public sensibilities" and demanded some action regarding the "yellow journalism" of murder-glorification that featured in the paper. Yellow journalism is described as exaggerations of news events, scandal-mongering, or sensationalism, designed to boost a newspapers circulation and increase sales - which includes the sensationalizing of murder. Exactly what the Citizen letter was calling out.

"The term was coined in the mid-1890s to characterize the sensational journalism that used some yellow ink in the circulation war between Joseph Pulitzer's New York World and William Randolph Hearst's New York Journal. The battle peaked from 1895 to about 1898, and historical usage often refers specifically to this period. Both papers were accused by critics of sensationalizing the news in order to drive up circulation, although the newspapers did serious reporting as well. An English magazine in 1898 noted, "All American journalism is not 'yellow', though all strictly 'up-to-date' yellow journalism is American" Wikipedia.

"During the Gilded Age, yellow journalism flourished, using fake interviews, false experts and bogus stories to spark sympathy and rage as desired. Joseph Pulitzer’s New York World published exaggerated crime dramas to sell papers. In the 1890s, plutocrats like Randolph Hearst and his Morning Journal used exaggeration to help spark the Spanish-American War. When Hearst’s correspondent in Havana wired that there would be no war, Hearst — the inspiration for Orson Welles' "Citizen Kane" — famously responded: “You furnish the pictures, I’ll furnish the war.” Hearst published fake drawings of Cuban officials strip searching American women — and he got his war". Politico.

We now have a May 8th 1974 Citizen card mailed on the same day as the Los Angeles release date of Citizen Kane, calling for advertisements not to be run about the Badlands movie, just like William Randolph Hearst insisted his paper do with the Orson Welles movie Citizen Kane, and an insistence in both cases that "yellow journalism" was not acceptable, beginning on February 11th 1974 and ending on May 8th 1974.

We could include the January 29th 1974 Exorcist letter featuring the much sensationalized William Friedkin movie "The Exorcist", in which the author plays down its impact, claiming it "the best satirical comedy that I have ever seen." In the final correspondence of 1974, on July 8th, the author complains about the "superiority complex" of Count Marco, who gave outrageous advice to women in a San Francisco Chronicle column geared towards sensationalism - the presentation of stories in a way that is intended to provoke public interest or excitement, at the expense of accuracy. The emphasis exhibited by the author of these three communications, was of somebody clearly irked by the newspapers coverage of events current and past, in the form of "yellow journalism." It certainly brings a new perspective to the phrase "red with rage." 

When tying a single author or group to the mailing of the S.L.A letter, Citizen card and Red Phantom letter together under one banner, it is important to understand the focus of the communications as a whole. This all began on February 3rd 1974 with the S.L.A letter, postmarked "U.S. Postal Service, CA 913 PM 3 FEB 1974". This was the eve of the kidnapping of Patricia Campbell Hearst, which occurred on February 4th 1974. The letter signed off with "a friend". On February 10th 1974, a Symbionese Liberation Army member mailed a typed letter to the Hearst family at 233 W. Santa Inez Ave, Hillsborough, California, postmarked "U.S. Postal Service, CA 940 PM 10 FEB 1974". It too was signed off with "A friend". The impending and eventual kidnapping of Patricia Hearst may have been the inspiration behind the latter three communications in 1974, with the Hearst family and corporation the main focus. In other words, the S.L.A letter, Citizen card and Red Phantom letter were aimed at William Randolph Hearst Sr (deceased), William Randolph Hearst Jr and the Hearst Corporation as a whole. The Symbionese Liberation Army ran on an anti-capitalist agenda and against everything the Hearst Corporation stood for, hence their targeting of the young woman and the forced distribution of food, sourced from the Hearst's and given to the working class in the form of a ransom. Despite sending an incoherent message to the American public, the Symbionese Liberation Army had extremely well-educated members, which may have played a part in the design of the Citizen card and subsequent Red Phantom letter, with references to the Hearst family. In particular, the "signing off" portion of each correspondence.  

Writing to the San Francisco Chronicle on May 8th 1974, the author reprimanded the editors for "lack of sympathy for the public, as evidenced by your running of the ads for the movie "Badlands". This was the primary focus of the card, before signing off the communication with "A citizen". Notice the correlation between this and the February 10th 1974 typed Hearst family letter, ending with "A friend". There may have been a tinge of sarcasm portrayed in the Citizen card in relation to the "running of ads" for the Badlands movie. 

In the FBI files pertaining to the Symionese Liberation Army, a memorandum dated April 30th 1974 indicated that the Hearst Corporation was prepared to offer a 4 million dollar food plan on May 3rd 1974 for the safe return of their daughter. The Sunday San Francisco Examiner, asking for "citizen assistance" had already run a feature article on April 28th 1974 (based on the file information), which resulted in the paper receiving 75 telephone calls offering information regarding S.L.A members. Only 10 days later, on May 8th 1974, the 'Citizen' card arrived at the San Francisco Chronicle, scolding the paper for its movie advertisements, before signing off the letter with "A citizen". 

However, this may not have been the only explanation for the "citizen" reference. Here is an extract from Wikipedia:
"The quasi-biographical film (Citizen Kane) examines the life and legacy of Charles Foster Kane, played by Welles, a character based in part upon the American newspaper magnates William Randolph Hearst and Joseph Pulitzer, Chicago tycoons Samuel Insull and Harold McCormick, and aspects of the screenwriters' own lives. Upon its release, Hearst prohibited mention of the film in any of his newspapers. Kane's career in the publishing world is born of idealistic social service, but gradually evolves into a ruthless pursuit of power". The film incensed William Randolph Hearst Sr and started a long running feud with Orson Welles, resulting in the newspaper magnate forbidding his newspapers to run any advertisements for the Citizen Kane movie. Does this ring any bells? - "Sirs, I would like to expression my consternation concerning your poor taste + lack of sympathy for the public, as evidenced by your running of the ads for the movie "Badlands". why don't you show some concern for public sensibilities + cut the ad?  A citizen." 

This was detailed in History.com with the title 'William Randolph Hearst Stops Citizen Kane Ads': "One of Hollywood’s most famous clashes of the titans–an upstart “boy genius” filmmaker versus a furious 76-year-old newspaper tycoon–heats up on this day in 1941, when William Randolph Hearst forbids any of his newspapers to run advertisements for Orson Welles’ Citizen Kane. Only a few days after the screening, Hearst sent the word out to all his publications not to run advertisements for the film. Far from stopping there, he also threatened to make war against the Hollywood studio system in general, publicly condemning the number of “immigrants” and “refugees” working in the film industry instead of Americans, a none-too-subtle reference to the many Jewish members of the Hollywood establishment. Hearst’s newspapers also went after Welles, accusing him of Communist sympathies and questioning his patriotism".

In the Telegraph under the title 'Citizen Kane 'feud' between Orson Welles and William Randolph Hearst thaws after 70 years' it states "When Welles' masterpiece was released in 1941 Hearst, who was the partial inspiration for the movie, was incensed and banned his newspapers from reviewing or even mentioning it".

Therefore, it must be an amazing coincidence that the Citizen card called for "cutting the ads" before signing off with "A citizen". Not to mention that the release date in Los Angeles, California for the movie Citizen Kane was May 8th 1941 - the exact date this correspondence was postmarked, on May 8th 1974.   

Two months later, the Red Phantom letter arrived at the San Francisco Chronicle, postmarked July 8th 1974, targeting the 'male chauvinistic' Count Marco column of Marc H. Spinelli. This letter continued the theme, demanding that the Chronicle "cancel the Count Marco column", before signing off with the rather curious "Red Phantom (red with rage)". But what did this pseudonym have to do with the Hearst family?

Entitled 'The Phantom: The Complete Newspaper Dallies Volume One 1936-1937' by Lee Falk, it states "Leon Harrison Gross was born on April 28, 1911, in St. Louis. By the time he sold his first comic strip, Mandrake the Magician, he had changed his name to Lee Falk. His tendency was to shave a few years off his age and he often told interviewers he was a 19-year-old junior at the University of Illinois when he started Mandrake. Actually he was 23, still an impressively young age to sell a comic strip to the largest syndicate in America, William Randolph Hearst's King Features. Two years later he came up with 'The Phantom' and King bought that one as well". See here.

​Founded in 1914, King Features Syndicate, Inc. is a print syndication company owned by Hearst Communications that distributes about 150 comic strips, newspaper columns, editorial cartoons, puzzles, and games to nearly 5,000 newspapers worldwide. King Features Syndicate is a unit of Hearst Holdings, Inc., which combines the Hearst Corporation's cable-network partnerships, television programming and distribution activities, and syndication companies. King Features' affiliate syndicates are North America Syndicate and Cowles Syndicate. Each week, Reed Brennan Media Associates, a unit of Hearst, edits and distributes more than 200 features for King Features. Wikipedia.

The author of the July 8th 1974 Red Phantom letter was again demanding that the newspaper "cut or cancel" another section they disliked. The question being - was this another sarcastic dig at the Hearst Corporation, threatening to release 'The Phantom', a fictional costumed crime-fighter, to seek retribution on the San Francisco Chronicle and Count Marco. Except this time, 'The Phantom' had morphed into the 'Red Phantom', red with rage.

The four 1974 communications were mailed in and around the height of the Symbionese Liberation Army, beginning on January 29th 1974, just days before the kidnapping of Patricia Campbell Hearst and ending on July 8th 1974, just six weeks after the deadly shootout between Symbionese Liberation Army members and law enforcement on May 17th 1974, resulting in the deaths of six urban militants. The Hearst family being front and center of everything.    

The Exorcist letter was mailed to the San Francisco Chronicle on January 29th 1974 featuring a 'review' of the 1973 William Friedkin Exorcist movie, a verse from The Mikado's 'Tit-Willow', the usual threat and some curious Asian characters at the foot of the letter, whitewashed from the January 31st San Francisco Chronicle article regarding this communication. Just three days later, a follow-up correspondence, widely labelled the S.L.A letter was mailed, highlighting the word "Kill" at its foot. The Asian characters on the Exorcist letter have been 'decoded' by Zodiac researcher Kevin Robert Brooks to spell "To Kill", opening up the possibility that the designer of the S.L.A letter was immediately responding to the Chronicle's whitewashing of the characters, giving us the solution and thus verifying they were the author of both. However, without being able to convince everybody or anybody of the "To Kill" solution, more is needed in tying these two communications together, along with the May 8th 1974 Citizen card and July 8th 1974 Red Phantom letter. 

The Zodiac Killer had a penchant for the theatrical, appearing in costume at Lake Berryessa on September 27th 1969 and citing Gilbert & Sullivan's Mikado twice in his July 26th 1970 letter. The 1974 Exorcist letter would feature film and theater, the Citizen card expressed consternation at the 1973 Badlands movie and the Red Phantom letter, likewise, may have been referencing a theatrical release of the film El Espectro Rojo or Red Phantom, as detailed by Tom Voigt on Zodiackiller.com. This provides another avenue of inspiration behind the Red Phantom pseudonym chosen by the July 8th 1974 author. It is certainly in keeping with the film and theater angle, heavily laden in the 1974 communications. Tom Voigt articulates that El Espectro Rojo or Red Phantom played at the Port Theater in Mill Valley, Marin County on the 27th and 28th April 1974, just three months prior to the arrival of the Red Phantom letter. The critical part now, is unearthing the inspiration behind the S.L.A letter from a film or theatrical standpoint, and connecting this to a Symbionese Liberation Army member. In a previous article, it has been shown that a Symbionese Liberation Army member typed a letter to the Hearst Family on February 10th 1974 and signed off with "A friend" - a few days earlier, the San Francisco Chronicle S.L.A letter arrived, also signing off with "a friend".  

One possible author of the S.L.A letter (and possibly the Exorcist letter) was Sara Jane Olson (born Kathleen Ann Soliah on January 16, 1947). She was a member of the Symbionese Liberation Army in the 1970s. She grew up in Palmdale, California, the daughter of Norwegian-American parents, Elsie Soliah (née Engstrom) and Palmdale High School English teacher and coach Martin Soliah. Engström, Engstrøm and Engstrom are surnames of Swedish and Norwegian origin. Was she responsible for authoring the S.L.A letter on February 3rd 1974, one or two days before the kidnapping of Patricia Hearst?

To examine this possibility we have to examine her background. The S.L.A letter was postmarked "U.S. Postal Service, CA 913 PM 3 FEB 1974". Kathleen Ann Soliah was brought up in Palmdale, Los Angeles County, California, often frequenting the nearby census-designated area of Agua Dulce. In fact, Agua Dulce was the commuter route from Palmdale to 1466 East 54th Street, Los Angeles -  the site of the deadly shootout between Symbionese Liberation Army members and law enforcement on May 17th 1974, resulting in the deaths of six urban militants. The Symbionese Liberation Army had its main headquarters in San Francisco and Los Angeles. Agua Dulce had a postal zip code of 91390, tying in nicely with the postmark on the February 3rd 1974 S.L.A letter. It is less than five miles from Palmdale. 

To discover the author of the 1974 communications attributed to the Zodiac Killer, we may be looking for somebody familiar with the Zodiac murders and correspondence (particularly with regards to the Exorcist letter), but also, somebody with film and theatrical leanings that may have a strong bearing on the design of the S.L.A letter.

​Kathleen Ann Soliah, after leaving high school, studied acting at nearby Antelope Valley College in Lancaster, California, near Palmdale. She then moved to study theater at the University of California at Santa Barbara, where she met her boyfriend and future Symbionese Liberation Army member, James Kilgore. After graduating in 1969 her radicalization intensified during future years in the Bay Area, eventually becoming friends with the notorious Angela Atwood. This is where a blend of her theatrical leanings, Norwegian-American heritage and a passion for writing may have come into play.

S.L.A  member and boyfriend of Kathleen Ann Soliah, James Kilgore, was ultimately jailed in 2002 for his participation in the April 21st 1975 Crocker National Bank robbery that resulted in the murder of bank customer Myrna Lee Opsahl. “I accept full responsibility for my actions on that day,” said Kilgore, a former San Rafael High School honors student and one-time economics major who became an SLA bomb maker and eventually a professor at the University of Cape Town" ReligionNewsBlog. The July 8th 1974 'Red Phantom' letter was mailed from San Rafael, Marin County, and the May 8th 1974 'Badlands' letter was mailed from Alameda County, where the County Coroner's Office received Symbionese Liberation Army threats after the 1973 murder of Marcus Foster. Espectro Rojo or Red Phantom played at the Port Theater in Mill Valley, Marin County.      

When looking for the inspiration behind the S.L.A letter and "Old Norse", keeping in line with the theatrical influences of the Exorcist letter only days earlier, I looked for a link to the theater in the S.L.A letter too. Whoever designed the Exorcist letter, mimicked the July 26th 1970 Mikado letter mailed by Zodiac. The Mikado is 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. Hedda Gabler is a play written by Norwegian playwright Henrik Ibsen. Ibsen was present at the world premiere which took place on  January 31st 1891 at the Residenztheater in Munich. It is recognized as a classic of realism, nineteenth century theater and world drama. The title character, Hedda, is considered one of the great dramatic roles in theater.

Symbionese Liberation Army member, Angela DeAngelis "General Gelina" Atwood died in the Los Angeles shootout on May 17th 1974. A year earlier "Kathleen Ann Soliah worked as a cocktail waitress in San Francisco and took small acting roles. She befriended Angela Atwood, the daughter of a New Jersey Teamsters boss who, like Soliah, had grown up in a middle-class home before coming to Berkeley. Atwood, who appeared with Soliah in "Hedda Gabler," helped her friend get a job at the Great Electric Underground, an upscale restaurant in the Bank of America world headquarters". link.

​If Kathleen Ann Soliah authored the February 3rd 1974 S.L.A letter referencing her Norwegian heritage of "Old Norse" and signing off with "a friend", then she was likely the author of the February 10th 1974 S.L.A Hearst letter, again signing off with "A friend". ​Her role in the Norwegian Hedda Gabler theater production would be an influence she carried forward, when we consider the presence of "Old Norse" in the February 3rd 1974 communication. The premiere of Hedda Gabbler opened on January 31st - the same day in history that the San Francisco Chronicle featured the arrival of the Exorcist letter. 

"At this period of Ibsen's youth, Norway experienced a nationalist awakening. The new literary generation, after 400 years of Danish rule, sought to revive the glories of Norwegian history and medieval literature. The middle ages were glorified as well because the romantic movement was in full swing throughout Europe. Thus, when Ole Bull, the great violinist, founded a norse theater at Bergen, the project met with enthusiastic approval from all the youthful idealists eager to subvert the influence of Danish culture.  Encouraged by the success of Ole Bull’s Norse theater in Bergen, enthusiasts of nationalist poetry in the capital also founded a new theater in direct competition with the conservative, Danish-influenced Christiania Theater. Asked to direct this new venture, Ibsen’s promised salary was twice the amount he received at Bergen, about six hundred specie dollars  The problems of Ibsen’s social dramas are consistent throughout all his works. Georg Brandes, a contemporary critic, said of Ibsen, as early as the 1860s, that “his progress from one work to the other is not due to a rich variety of themes and ideas, but on the contrary to a perpetual scrutiny of the same general questions, regarded from different points of view.”
Hedda Gabler, with its emphasis on individual psychology, is a close scrutiny of a woman like Nora Helmer or Mrs. Alving, who searches for personal meaning in a society which denies freedom of expression". link.

The Det norske Theater is a former theater in Bergen, Norway, and regarded as the first pure Norwegian stage theatre. It opened in 1850 by primus motor, violinist Ole Bull, and closed in 1863, after a bankruptcy. Norwegian (norsk) is a North Germanic language spoken mainly in Norway, where it is the official language. Along with Swedish and Danish, Norwegian forms a dialect continuum of more or less mutually intelligible local and regional varieties, and some Norwegian and Swedish dialects, in particular, are very close. These Scandinavian languages, together with Faroese and Icelandic as well as some extinct languages, constitute the North Germanic languages. Faroese and Icelandic are hardly mutually intelligible with Norwegian in their spoken form because continental Scandinavian has diverged from them. While the two Germanic languages with the greatest numbers of speakers, English and German, have close similarities with Norwegian, neither is mutually intelligible with it. Norwegian is a descendant of Old Norse, the common language of the Germanic peoples living in Scandinavia during the Viking Era. Wikipedia.

When we consider the identity of the author of the July 8th 1974 Red Phantom letter, we have to consider the person they are addressing and what do they stand for. The letter states "Editor: Put Marco back in the hell-hole from whence it came- he has a serious psychological disorder- always needs to feel superior. I suggest you refer him to a shrink. Meanwhile, cancel the Count Marco column. Since the count can write anonymously, so can I----the Red Phantom (red with rage)". 

​The obituary of Marc H. Spinelli began with "Marc H. Spinelli, better known to Chronicle readers as Count Marco, a columnist who gave outrageous advice to women for 15 years. As Count Marco, Mr. Spinelli was a star performer in a circulation war in the 1960s between The Chronicle and other Bay Area newspapers. At the height of his fame, he wrote his newspaper column, appeared on his own daily television show, wrote three books, won prizes and developed a huge audience that was either amused or appalled by his words" sfgate.. Most of the people dissatisfied with his newspaper column were disgruntled women, appalled with his views they deemed as male chauvinistic and sexist - so a good case can be argued that the author of the Red Phantom letter was likely a woman fighting for women's rights, upset by his perceived superiority complex. On the flip side, it could be the Zodiac Killer angered by the columnist for putting women down, despite the fact he had no problem murdering them.

His book 'Beauty and the Beast' was littered with distasteful comments towards women, such as 'Someone once asked me, "do you really believe a husband should beat his wife?" And I answered "Yes, most emphatically. There are times when she should not only be beaten, but kicked when she's down". Other examples can be readily found in the newspaper columns running up to the Red Phantom letter of May 8th, shown here in the 'Ten Days of Count Marco' by Zodiac researcher Michael Cole. Two such examples are "Female comics, she says, must play the role of ugly duckling or half-wit in order to get laughs. The real uglies of course are the ones who don't make a living at it: the average American housewife who prowls the public streets with her hair in rollers and her stretch pants defying all laws of container control" and "Besides, if a stewardess can't handle a flippant male passenger, then I don't think she's strong enough to open an emergency door".

So, it wouldn't be too surprising if the author of the Red Phantom letter was a woman with aspirations of equal rights and respect, who was familiar with the San Francisco Chronicle newspaper and despised the views of Count Marco, rather than a serial killer known for stabbing women in the back, and widely portrayed in many Zodiac circles as a man who vented most of his anger towards the women he encountered. This dichotomy, however, is largely disregarded, when the overarching desire is to believe the Zodiac Killer resurfaced in 1974 for phase two of his 'escapades'. Having previously poured huge doubt on the February 3rd 1974 S.L.A letter as Zodiac material (likely authored by a female member of the Symbionese Liberation Army), and questioned the authenticity of the Badlands or Citizen card, we shall now examine the Red Phantom letter from a similar perspective. We shall also look at the origin of the anonymous signature "Red Phantom (red with rage)"   

"The United Federated Forces of the Symbionese Liberation Army (SLA) was an American left-wing militant organization active between 1973 and 1975 that considered itself a vanguard army. The group committed bank robberies, two murders, and other acts of violence. In his manifesto "Symbionese Liberation Army Declaration of Revolutionary War & the Symbionese Program", Donald DeFreeze wrote, "The name 'symbionese' is taken from the word symbiosis and we define its meaning as a body of dissimilar bodies and organisms living in deep and loving harmony and partnership in the best interest of all within the body. "This political symbiosis DeFreeze describes means the unity of all left-wing struggles, feminist, anti-racist, anti-capitalist, and others. DeFreeze wanted all races, genders, and ages to fight together in a left-wing united front, and to live together peacefully". Wiki.

The group mailed large quantities of mail to the San Francisco Chronicle, San Francisco Examiner, and various television and radio stations, as well as many other outlets. They ranged from demands and threats, to spouting off Symbionese Liberation Army doctrine. Their membership was progressive, having a high proportion of female members with a staunch feminist ideology.

Therefore, bearing in mind the S.L.A letter, is it possible one of the female Symbionese Liberation Army members took umbrage over the Count Marco, San Francisco columnist's views on women and mailed a correspondence to him, telling him to get "back in the hell-hole from whence it came"? Or was the Zodiac having a mid-life crisis becoming more liberal with his views - rather than his bullets.
​ 
Here is a small fraction of the literature composed by female members of the Symbionese Liberation Army and their struggle for equality in the sexes. 

The 'Woman Question' referred to in the FBI 'Hearnap' (Hearst Kidnap) files "is translated from the French term querelle des femmes (literally, 'dispute of women') refers both to an intellectual debate from the 1400s to the 1700s on the nature of women and feminist campaigns for social change after the 1700s. While the French phrase querelle des femmes deals specifically with the Renaissance period, 'the woman question' in English (or in corresponding languages) is a phrase usually used in connection with a social change in the later half of the 19th century, which questioned the fundamental roles of women in Western industrialized countries such as the United Kingdom, the United States of America, Canada, and Russia. Issues of women's suffrage, reproductive rights, bodily autonomy, property rights, legal rights, and medical rights, and marriage dominated cultural discussions in newspapers and intellectual circles. While many women were supportive of these changing roles, they did not agree unanimously. Often issues of marriage and sexual freedom were most divisive". Wikipedia.

The Symbionese Liberation Army women members often referenced a "cell" or "collective", and this leads us nicely on to the meaning behind "Red Phantom (red with rage)". 

Many have searched for the inspiration behind "Red Phantom" from a Zodiac perspective. Comic designers, movie makers and newspaper editors throughout the ages have attributed pseudonyms to fantasy characters and murderers alike. In other words, they have just been manufactured by the imagination of the creator and not necessarily copied or inspired by something previous. The "Red Phantom" pseudonym may just have been conjured up on the spur of the moment. However, I would like to focus on the only word the author used twice - the word "red."  If the letter was written by a female member of the Symbionese Liberation Army with feminist ideals, could the word "red" have been invoked for a deeper meaning.

"The late 60s saw the emergence of the Women’s Movement in Britain. In 1969 in London the Women’s Red Liberation Workshop established itself, developing consciousness raising groups and attempting to articulate and understand the ways in which women felt themselves to be oppressed and exploited. In the same year, a group of socialist women active in the Vietnam Solidarity Campaign started producing a journal called “Socialist Woman”, whose aims were both to impress on the left the importance of the “Woman Question” – to publicise the struggles of women in Britain and internationally and to try to develop a socialist analysis of women’s oppression it was to be distributed through the newly formed Socialist Woman Groups".  Redflagwalks. There was also the emergence of the socialist-feminist Red Rag Magazine championing women's rights. These publications inspired women internationally, including female Americans fighting for a better future. Were these publications and the rise of "red feminism", the catalyst for a push-back against the male chauvinist 'pigs' of America, including the Count Marco column of Marc H. Spinelli? Or did the Zodiac Killer undergo a complete transformation after murdering three women (5 people in total) - now rallying for "public sensibilities", despite being attributed with the threatening Exorcist letter just five months earlier?

                                                                     "the Red Phantom (red with rage)".      
​
​S.L.A LETTER NOT ZODIAC - AND HERE IS THE FBI FILE TO PROVE IT

The S.L.A letter supposedly received at the San Francisco Chronicle from the Zodiac Killer on February 14th 1974, was actually mailed on or slightly before February 3rd 1974 from Los Angeles County, one day before the kidnapping of Patricia Campbell Hearst. "Sla" in Old Norse means strike or smite - and smite in archaic usage such as Old Norse is to kill or severely injure. In a previous article entitled 'The Symbionese Liberation Army and the Zodiac Killer', an S.L.A member was considered as the possible author of the February 3rd 1974 S.L.A letter because of the "Old Norse" reference. Sara Jane Olson (born Kathleen Ann Soliah on January 16, 1947) was a member of the Symbionese Liberation Army in the 1970s. She grew up in Palmdale, California, the daughter of Norwegian-American parents.

The S.L.A letter was postmarked  "U.S. Postal Service, CA 913 PM 3 FEB 1974" - the letter began with the word "Dear" and signed off with the rather tame "a friend". Zodiac researchers, understandably don't want to believe the letter was mailed on February 3rd 1974, because they have a vested interest going back decades, including printed material based on a 'Zodiac Killer' responding to the kidnapping of Patricia Campbell Hearst by mailing this letter on or around February 14th 1974, despite the fact nothing in the S.L.A letter refers to the kidnapping. So, just for arguments sake, let us assume the Zodiac Killer mailed the letter on February 14th 1974, signing off the letter with "a friend".

​On February 10th 1974, just 4 days prior to the S.L.A letter, a typewritten letter in a white envelope was mailed to the Hearst family, postmarked "U.S. Postal Service, CA 940 PM 10 FEB 1974", bearing the typewritten address "R.A Hearst Family, 233 W. Santa Inez Ave, Hillsborough, Cal, 94010??". It read [corrected for spelling] : 

Dear Hearst Family, I am white, and I am sorry I joined the people who have your daughter. I saw her Wednesday and she was alright. She is brave and beautiful and innocent. Don't let her marry that Weed man. He talked to our brass last month and said how to set it up. He said if he marries her, he must have enough money to hold up his head. He got his idea from Miss Angela Davis, who gives orders and ideas to our brass. I am so ashamed to belong  I am trying to get out easy, but God help me if they find out I write this. They are animals, but I don't think they will hurt her. God bless you, and God forgive me.

                                                                 A friend   ​ 

For those still believing the S.L.A letter was mailed by the Zodiac Killer on February 14th 1974 - here we have a Symbionese Liberation Army member mailing a typewritten letter to the Hearst family on February 10th 1974, four days prior, beginning the letter with "Dear" and signing off with "A friend". Then, a matter of days later, the Zodiac Killer has returned after a near 3-year hiatus and just happens to accidentally mimic the Hearst letter (which wasn't published), beginning the letter with "Dear" and signing off with "a friend", while writing about the Symbionese Liberation Army. Even the die-hard proponents of a February 14th 1974 mailing cannot believe this to be the case.

The 'Hearst Family' letter may have been authored by Sara Jane Olson (born Kathleen Ann Soliah), who could also be responsible for the S.L.A letter mailed from Los Angeles (913) just a week earlier, on February 3rd 1974. The "Old Norse" element of the letter drawn from her Norwegian-American ancestry.​ Both communications began with "Dear" and ended with "a friend". 

The 'Hearst Family' typewritten letter and envelope can be seen below, postmarked February 10th 1974, accompanied by a notation of "For FBI or Family" [corrected].

On November 6th 1973 two members of the urban militant group 'The Symbionese Liberation Army' killed school superintendent Marcus Foster and badly wounded his deputy, Robert Blackburn, as the two men left an Oakland school board meeting. Two months later on January 10th 1974 Joseph Remiro and Russell Little were arrested, charged and convicted of the murder of Marcus Foster. They would become the focus of a ransom note (February 7th) mailed by the Symbionese Liberation Army shortly after the kidnapping of Patricia Campbell Hearst on February 4th 1974. It read "We're holding your daughter Patricia Hearst and we're never going to give her back to you unless you pigs let Remiro and Little out of prison." On April 15th 1974 members of the Symbionese Liberation Army, including Patricia Hearst brandishing an M1 carbine, burst into the Hibernia Bank branch at 1450 Noriega Street, San Francisco, stole $10,000 and shot two civilians. Money needed to secure housing and supplies to continue their recruitment of new members to the cause, and carry on the fight to release their jailed comrades.

At about the same time, the Badlands film directed by Terrence Malick, and starring Martin Sheen and Sissy Spacek was on general release in New York (24th March 1974) and Los Angeles (29th March 1974). The story, though fictional, is loosely based on the real-life murder spree of Charles Starkweather and his girlfriend, Caril Ann Fugate, in 1958. The San Francisco Chronicle ran advertisements for the film, which may very well have prompted a reaction from the Symbionese Liberation Army, who were still fighting for the release of S.L.A  members Joseph Remiro and Russell Little. On May 8th 1974 a communication was mailed to the San Francisco Chronicle, stating "Sirs -- I would like to expression my  consternation concerning your poor taste + lack of sympathy for the public, as evidenced by your running of the ads for the movie "Badlands," featuring the blurb: "In 1959 most people were killing time. Kit + Holly were killing people." In light of recent events, this kind of murder-glorification can only be deplorable at best (not that glorification of violence was ever justifiable) why don't you show some concern for public sensibilities + cut the ad?  A citizen." The Symbionese Liberation Army [supposition] could not understand, from their perspective, the hypocrisy of running advertisements for the 'Badlands' movie glorifying the murder of innocent civilians, while at the same time aiding their newspaper circulation by protracted coverage of the murder of Marcus Foster by Remiro and Little. The Chronicle, as they saw it, was benefiting financially from the murder-glorification of "recent events" (Marcus Foster) that they personally felt wronged by.  

In the FBI files regarding the Symionese Liberation Army (shown above), a memorandum dated 30th April 1974 indicated that  the Hearst Corporation was prepared to offer a 4 million dollar food plan on May 3rd 1974 for the safe return of their daughter. The Sunday San Francisco Examiner asking for "citizen assistance" had already run a feature article on April 28th 1974 (based on the file information), which resulted in the paper receiving 75 telephone calls offering information regarding S.L.A members. Only 10 days later, on May 8th 1974, the 'Citizen' card arrived at the San Francisco Chronicle, scolding the paper for its movie advertisements, before signing off the letter with "A Citizen". I'm sure the irony wasn't lost on the Symbionese Liberation Army.  

In a previous article entitled 'The Symbionese Liberation Army and the Zodiac Killer', an S.L.A member was considered as the possible author of the February 3rd 1974 S.L.A letter because of the "Old Norse" reference. Sara Jane Olson (born Kathleen Ann Soliah on January 16, 1947) was a member of the Symbionese Liberation Army in the 1970s. She grew up in Palmdale, California, the daughter of Norwegian-American parents. So, can we wipe away any preconceived notions about the S.L.A letter, Badlands card and Red Phantom letter with respect to the Zodiac Killer, and view them from the perspective of having been written by a woman, or at the very least, a member or affiliate of the Symbionese Liberation Army. Here is the text from the three communications:
[1] The S.L.A letter: Dear Mr Editor, Did you know that the initials SLAY spell "sla", an old Norse word meaning "kill". a friend.

[2]The Badlands card: Sirs -- I would like to expression my consternt (crossed out) consternation concerning your poor taste + lack of sympathy for the public, as evidenced by your running of the ads for the movie "Badlands," featuring the blurb: "In 1959 most people were killing time. Kit + Holly were killing people." In light of recent events, this kind of murder-glorification can only be deplorable at best (not that glorification of violence was ever justifiable) why don't you show some concern for public sensibilities + cut the ad?  A citizen.
​ 
[3]The Red Phantom letter: Editor: Put Marco back in the hell-hole from whence it came- he has a serious psychological disorder- always needs to feel superior. I suggest you refer him to a shrink. Meanwhile, cancel the Count Marco column. Since the count can write anonymously, so can I----the Red Phantom (red with rage).

Other than the psychological connection we touched upon in the Edward C. Adams article, what other possible reasons would the Zodiac Killer have for addressing Count Marco, a columnist who gave outrageous advice to women via the San Francisco Chronicle for 15 years. A murderer, who didn't give a second thought to shooting two women a total of 10 times, before also ruthlessly stabbing Cecelia Shepard in the back and abdomen 10 times, was now, just a few years later, objecting to "murder-glorification" and bigoted advise to women. A man devoid of empathy and driven by an insatiable ego had now become the proverbial "snowflake", quivering and upset because of an advice columnist and a film advertisement. Had the Zodiac Killer really achieved a complete transformation in just a matter of three years. If we believe the Exorcist letter as genuine Zodiac material, stating "If I do not see this note in your paper, I will do something nasty, which you know I'm capable of doing", then the transformation had occurred in just over 3 months.  

The Zodiac Killer could have been toying with the newspapers, disingenuously feigning concern while laughing at the authorities - or he was simply not the author of these banal communications that surfaced in 1974.

The Symbionese Liberation Army didn't have unrealistic ideals, but unfortunately used contemptible means to achieve them.

"In his manifesto "Symbionese Liberation Army Declaration of Revolutionary War & the Symbionese Program", Donald DeFreeze wrote, "The name 'symbionese' is taken from the word symbiosis and we define its meaning as a body of dissimilar bodies and organisms living in deep and loving harmony and partnership in the best interest of all within the body. "This political symbiosis DeFreeze describes means the unity of all left-wing struggles, feminist, anti-racist, anti-capitalist, and others. DeFreeze wanted all races, genders, and ages to fight together in a left-wing united front, and to live together peacefully". Wikipedia.

​With many female S.L.A members aligned with feminist ideals, would it be that difficult to believe, that the Red Phantom letter was aimed at Marc H. Spinelli (Count Marco) and his San Francisco Chronicle column because of its often belittling or denigrating comments towards women?

​"Betty Friedan, whose 1963 book The Feminine Mystique is credited with reviving the feminist movement, originally called the strike at the conference of the National Organization for Women in March. As head of the hastily assembled National Women's Strike Coalition, she had predicted an impressive turnout. Inevitably, the women had their detractors. The San Francisco Chronicle's Count Marco called the strike "a day of infamy and shame" and urged his supporters to wear black armbands "mourning the death of femininity." link. 
"Count Marco was an extremely popular columnist for the San Francisco Chronicle with an outrageous persona; this book of advice (Beauty and the Beast) on how to please a man was mainly for the ladies of "The Greatest Generation" and pre-boomers, whom it surely shocked and annoyed with its sexual frankness and its assumption that American women had everything to learn from European women; feminist readers now would be shocked by his assumption that women's lives are empty without masculine love and their main goal in life should be to please their "beasts." link.  In other words, the Red Phantom letter was authored by a female member of the Symbionese Liberation Army (or a male member with a belief in feminism) in order to confront the opinionated columnist. 

I am not a staunch advocate of handwriting analysis due to its subjective nature and the fact it can be disguised, but here is the Red Phantom letter next to an extract taken from a Symbionese Liberation Army notebook - written before the kidnapping of Patricia Hearst on February 4th 1974.

The S.L.A letter was postmarked - and likely mailed the day before the kidnapping of Patricia Campbell Hearst. The envelope bore the postmark "U.S. Postal Service, CA 913 PM 3 FEB 1974." Considering the February 3rd 1974 letter referred to the Symbionese Liberation Army and the brazen kidnapping of Hearst followed the next day, there is valid case for believing this urban militant group was responsible for the mailing of the S.L.A  letter. But could they have been responsible for the Exorcist letter too? On January 29th 1974 a communication, dubbed the Exorcist letter, arrived at the offices of the San Francisco Chronicle. It featured a critique of the  William Friedkin movie 'The Exorcist', followed by a sprinkling of The Mikado's Tit-Willow, the usual threat to print in paper, a set of Asian-style characters and finally the author signing off with Me-37 SFPD-0. However, the San Francisco Chronicle whitewashed the strange characters near the base of the letter. The Zodiac Killer hadn't written for nearly three years, so this may have been done to weed out any future hoaxers. If the author of the Exorcist letter, which was believed to be the Zodiac Killer, was to mail any future correspondence, he could use the contents whitewashed by the Chronicle to confirm he was the author of the January 29th 1974 communication. This had been done before, when "by knife" written on Bryan Hartnell's car door was withheld from publication after the Lake Berryessa attack on September 27th 1969.  

On January 31st, in an article entitled 'Zodiac Mystery Letter-the First Since 1971', the San Francisco Chronicle presented the Exorcist letter like so. Only two or three days had elapsed, when the S.L.A letter was also mailed to the Chronicle. But had the author of the February 3rd 1974 letter revealed something about the Exorcist letter known only to them and the police? Had the author of the S.L.A letter effectively decoded the Exorcist letter characters for them, but they just didn't realize? 

Just before the author signs off with "a friend" on the S.L.A letter, he highlights the word "Kill" at the foot of the letter, referencing Old Norse. In the identical position at the foot of the Exorcist letter the author highlights the strange characters in bold marker, before signing off with Me-37. Was the author of the S.L.A letter telling us that the word "Kill" could be decoded in the Exorcist letter characters, thereby confirming they were the author of both? The author of the S.L.A letter would not only have to know that characters existed at the foot of the Exorcist letter, because the San Francisco Chronicle had whitewashed them, but also know that they could possibly feature the word "Kill". Could the author of the S.L.A letter, if different from the author of the Exorcist letter, accidentally place the word "Kill" in the same position through two letters, and highlight them both in bold writing and quotation marks to signify their importance? 

The San Francisco Chronicle, along with law enforcement seemingly didn't make the connection, because it wasn't until a few years ago that Zodiac researcher Kevin Robert Brooks offered up a possible solution to the Asian-style characters. When rearranged they were the perfect continuation to the author's preceding paragraph.   

The Exorcist letter would now read "If I do not see this note in your paper, I will do something nasty, which you know I'm capable of doing. To Kill."
Was this the focus behind the entire S.L.A letter, using the Symbionese Liberation Army and "sla" as a precursor to providing the word "Kill" to the San Francisco Chronicle and law enforcement, and therefore verifying they were also responsible for the Exorcist letter? It seemed very fortunate that the word "Kill" in quotation marks was able to be formed by the Asian-style characters of the Exorcist letter, especially considering it was completely whitewashed from publication in the Chronicle.

If the Symbionese Liberation Army were responsible for the February 3rd 1974 S.L.A letter, then what are the chances they created the Exorcist letter too? - fashioned by weaving together traits of old Zodiac Killer letters such as the July 31st 1969 trinity and the Little List letter of July 26th 1970. Or did the Zodiac Killer simply strike gold, writing a letter about the ​Symbionese Liberation Army just one day before Patricia Hearst's kidnapping? 

There is another intriguing possibility albeit without foundation. The Zodiac Killer stopped his letter writing sometime in 1971, with his campaign of terror having probably run its course. What are the chances he pursued different avenues in life, before joining the Symbionese Liberation Army, or becoming affiliated with them in some capacity by the turn of 1974. He then fires off a quartet of diluted Zodiac letters under the umbrella of his new found affiliation. The Symbionese Liberation Army's notable year was 1974, responsible for the Patricia Hearst kidnapping, the raid on the Hibernia Bank and the May 17th deadly shootout in Los Angeles, where six members were shot or burnt to death at 1466 East 54th Street after a standoff with the Los Angeles Police Department. The third letter of the quartet was the 'Badlands' card stating "In light of recent events, this kind of murder-glorification can only be deplorable at best (not that glorification of violence was ever justifiable)", mailed one week before the shootout. Subsequent to the shootout only one more communication would arrive in 1974  - the Red Phantom letter of July 8th 1974 - then radio silence. No correspondence subsequent to 1974 would ever be attributed as genuine Zodiac material. 

The S.L.A letter with the wording "Dear Mr Editor, Did you know that the initials SLAY (Symbionese Liberation Army) spell "sla", an old Norse word meaning "kill". a friend" was postmarked one day before the kidnapping of media heiress Patricia Campbell Hearst by the urban militant group Symbionese Liberation Army. The FBI files state:
Qc64 Photocopy of envelope postmarked "U.S. Postal Service, CA 913 PM 3 FEB 1974", bearing the hand printed address "Editor San Francisco Chronicle San Francisco, California".
Qc65 Accompanying photocopy of sheet of paper bearing the hand printed message beginning "Dear Mr. Editor, Did you know that the.....".
The postmark of CA 913 indicates it was mailed in north Los Angeles, an area the Zodiac Killer had never previously mailed a communication from (the S.L.A had headquarters in Los Angeles). The same applied to the two subsequent 1974 mailings - the 'Badlands' card postmarked Alameda County on May 8th 1974 and the 'Red Phantom' letter postmarked San Rafael on July 8th 1974. The city of Los Angeles would become headline news for the 1466 East 54th Street deadly shootout between S.L.A members and law enforcement on May 17th 1974, leaving six members dead. 

​although received on June 4, was mailed in Alameda County nearly a month earlier, on May 8. There was no explanation for its delayed arrival at the Chronicle offices".    

Although we cannot say for certain who mailed the S.L.A letter, it was the second letter in a matter of five days after a three year 'hibernation' by the Zodiac Killer. If the S.L.A letter was mailed by the Zodiac Killer, it shows astonishing timing having been postmarked one day before the kidnapping of Patty Hearst, undoubtedly the Symbionese Liberation Army's most daring escapade thus far. But why was both this letter and the 'Badlands' postcard delayed in transit by a total of 38 days? Had somebody at the San Francisco Chronicle not realized the significance of these two mailings because of their lack of identifying features?    

For those believing the S.L.A letter was mailed by the Zodiac Killer, we have a letter mailed from Los Angeles to San Francisco, something the Zodiac had never done before - areas of California where the Symbionese Liberation Army had their headquarters. The Zodiac Killer then got lucky, writing about the Symbionese Liberation Army the day before Patty Hearst's kidnapping in Berkeley - all after a three year hiatus. The S.L.A letter signed off with "a friend", the 'Badlands' postcard signed off with "A citizen" and the 'Red Phantom' letter signed off with "the Red Phantom (red with rage)", none had the menacing introduction of "This is the Zodiac Speaking", none had the Zodiac crosshairs, none had a running victim count and none had any spelling errors. Were these three communications piggybacking off the return of the Zodiac Killer on January 29th 1974, or were all four communications in 1974 the work of somebody other than the Zodiac Killer?       

The Zodiac Killer wrote copious communications to the newspapers throughout 1969 and 1970, finally ceasing sometime in 1971. It would be nearly a three year hiatus, when suddenly four communications in approximately five months landed at the doorstep of the San Francisco Chronicle. Is it reasonable to assume that the Zodiac Killer just reappeared in 1974 for his encore performance, or something or someone else was responsible for the four correspondences that year? Who, in San Francisco appeared in 1973, ran through 1974, and effectively disappeared by 1975? - the Symbionese Liberation Army is high on that list. "The United Federated Forces of the Symbionese Liberation Army (SLA) was an American left-wing militant organization active between 1973 and 1975 that considered itself a vanguard army. The group committed bank robberies, two murders, and other acts of violence". Wikipedia.  In the previous article it was shown that the S.L.A letter was postmarked February 3rd 1974, not February 14th 1974 as widely touted. This changes the whole story surrounding this letter - now mailed one or two days before the kidnapping of Patty Hearst. Bearing in mind its contents, it's either an amazing stroke of good fortune for the Zodiac Killer, or it was most likely mailed by a member of the Symbionese Liberation Army, knowing that Patty Hearst was soon to be kidnapped from Berkeley, California.   

Operating out of San Francisco and Los Angeles, the members of the S.L.A would have certainly been aware of the Zodiac Killer - and in someway mirrored his form of domestic terrorism. 

"It wasn't until January 10, 1974 that Oakland Police found their first clues. Two men arrested during a gunfight with police in Concord had a truck full of Symbionese Liberation Army literature. Later that day in Concord, a house torched by arson was also full of SLA literature, a stockpile of weapons and two pipe-bombs. The police found a letter titled “The August Seventh Movement,” a group that claimed responsibility for shooting down two Oakland officers in a helicopter by sniper as well as a communique targeting state prison officials and their wives with death by cyanide. In November 1973, Superintendent Marcus Foster (the first black superintendent in the city) of the Oakland School Administration was shot and killed. Deputy Superintendent Robert Blackburn was seriously wounded. The attackers used bullets whose core had been removed and replaced with cyanide crystals. Letters and calls were made to the San Francisco Chronicle, the Alameda County Coroner's Office, and a Berkeley radio station by the Symbionese Liberation Army", Ghoulifornia.

The Symbionese Liberation Army, not only wrote threatening letters to the San Francisco Chronicle, but in similar fashion to the 'Phone call to Melvin Belli' on the Jim Dunbar KGO-TV show, the S.L.A  mailed a cut-and-paste lettered correspondence to KGO-TV. Therefore, isn't it very likely a militant group, operating between 1973 and 1975, who wrote letters to the San Francisco Chronicle, would likely be responsible for the S.L.A letter mailed one day before Patricia Hearst's kidnapping. Or is it more likely that the Zodiac Killer just resurfaced after nearly three years?

On May 8th 1974, twenty-three days after the April 15th 1974 Hibernia Bank Robbery,  the 'Badlands' or 'Citizen Card' was mailed to the San Francisco Chronicle from Alameda County, stating "In 1959 most people were killing time. Kit + Holly were killing people." In light of recent events, this kind of murder-glorification can only be deplorable at best (not that glorification of violence was ever justifiable) why don't you show some concern for public sensibilities + cut the ad?  A citizen." It too ended with a rather benign 'signature', similar to "a friend" on the S.L.A letter, and may have been mailed to mock the authorities, flavored with insincerity. 

S.L.A  member James Kilgore was ultimately jailed in 2002 for his participation in the April 21st 1975 Crocker National Bank robbery that resulted in the murder of bank customer Myrna Lee Opsahl. “I accept full responsibility for my actions on that day,” said Kilgore, a former San Rafael High School honors student and one-time economics major who became an SLA bomb maker and eventually a professor at the University of Cape Town" ReligionNewsBlog. The July 8th 1974 'Red Phantom' letter was mailed from San Rafael, and the May 8th 1974 'Badlands' letter was mailed from Alameda County, where the County Coroner's Office received threats after the 1973 murder of Marcus Foster. The January 29th 1974 'Exorcist' letter was mailed from either San Mateo or Santa Clara County, completing a list of communications mailed from areas the Zodiac Killer had never previously dispatched his correspondence from.  

Mike Rodelli, avid Zodiac researcher and author of the book 'The Inconceivable Double Life of a Notorious Serial Killer-The Hunt for Zodiac,' examined his suspect Kjell Qvale. It is a thorough and comprehensive analysis of every aspect of the Zodiac crimes from the perspective of his suspect, as well as a valuable resource on the case as a whole.

Mike Rodelli considered the wording on the S.L.A letter pertinent to his suspect from a Scandinavian perspective. The S.L.A letter read "Dear Mr Editor,   Did you know that the initials SLAY (Symbionese Liberation Army) spell "sla", an old Norse word meaning "kill". a friend." Kjell Qvale was a Norwegian-American business executive and was one of the key figures in the creation of the Jensen-Healey. He became the first distributor for Jaguar on the Pacific West Coast.

The author of the S.L.A letter by referencing "sla" and "old Norse" was certainly indicating they may have had a Scandinavian connection, although stating "sla" meant "kill" rather than "strike" may have suggested a loose connection through family. Here is an English-Old Norse Dictionary. Sara Jane Olson (born Kathleen Ann Soliah on January 16, 1947) was a member of the Symbionese Liberation Army in the 1970s. She grew up in Palmdale, California, the daughter of Norwegian-American parents, Elsie Soliah (née Engstrom) and Palmdale High School English teacher and coach Martin Soliah. Engström, Engstrøm and Engstrom are surnames of Swedish and Norwegian origin. Was she responsible for authoring the S.L.A letter on February 3rd 1974, one or two days before the kidnapping of Patricia Hearst, which she most likely had knowledge of?

"Kathleen Soliah was born in Fargo, North Dakota, while her family were living in Barnesville, Minnesota. When she was eight, her conservative Lutheran family relocated to Southern California. After graduating from the University of California, Santa Barbara, Soliah moved to Berkeley, California, with her boyfriend, James Kilgore.
On April 21, 1975, SLA members robbed the Crocker National Bank in Carmichael, California, in the process killing 42-year-old Myrna Opsahl, a mother of four depositing money for her church. Patty Hearst, who was switch getaway driver during the crime, provided the original information that led the police to implicate the SLA in the robbery and murder; she also stated that Soliah was one of the actual robbers. According to Hearst, Soliah also kicked a pregnant teller in the abdomen, leading to a miscarriage. Several rounds of 9 mm ammunition spilled on the floor and found in Opsahl's body during the robbery bore manufacturing marks that matched that of ammunition loaded in a 9 mm Browning Hi-Power semi-automatic pistol found by police in Soliah's bedroom dresser drawer at the SLA safehouse on Precita Avenue in San Francisco. In 2002, new forensics technology allowed police to link these shells definitively to those found at Crocker Bank prior to charging the former members of SLA, including Soliah, with the crime. Prosecutor Michael Latin said that Soliah was tied to the crime through fingerprints, a palm print, and handwriting evidence. The palm print was found on a garage door from a garage in which the SLA kept a getaway car". Wikipedia.

​The date the S.L.A letter was mailed changes the whole concept of what we can infer from its contents. On February 14th 1974 the Zodiac Killer is simply latching onto the publicity generated by the kidnapping of Patricia Hearst on February 4th 1974, but on February 3rd 1974 that whole dynamic changes. It now sheds much doubt on the Zodiac Killer being responsible for the S.L.A letter and a lot more besides.  

​S.L.A LETTER NOT ZODIAC - AND HERE IS THE FBI FILE TO PROVE IT

The Exorcist letter bore the postmark 'U.S. Postal Service CA 940 AM 29 Jan', listed in the FBI files as documents Qc62 and Qc63 with a lab number of D-740208094. The following month, in the February of 1974, the S.L.A. (Symbionese Liberation Army) letter arrived at the San Francisco Chronicle. This letter has been ascribed the date of February 14th 1974 on all major websites - and because it followed the Exorcist letter, it is listed in the FBI files as documents Qc64 and Qc65 (envelope and letter) with a lab number of D-740304063. The S.L.A letter stated "Dear Mr Editor, Did you know that the initials SLAY spell "sla", an old Norse word meaning "kill". a friend." The following analysis detailed below is my opinion only, and should not be regarded as fact. After reading this you can obviously come to your own conclusions.

In the FBI file below, it states "Enclosed for the Bureau is one photocopy and one xerox copy of letter and envelope received 2/26/74 from Inspector (redacted) Homicide Detail, San Francisco Police Department. Enclosed for Sacramento is one xerox copy of same letter. For the information of the Bureau, on 2/20/74, Inspector (redacted) advised that on 2/14/74 the enclosed letter was received by the San Francisco Chronicle and (redacted), reporter for the San Francisco Chronicle brought the letter to (redacted) as a possible Zodiac letter. (Redacted) thereafter turned the letter over to (redacted) questioned document examiner, United States Postal Office, San Francisco. Mr (redacted) has advised (redacted) that he feels the letter is a Zodiac letter".

I don't believe this letter is from the Zodiac Killer - it was likely mailed by the Symbionese Liberation Army, or one of their members. In fact, it pours huge doubt on the January 29th 1974 Exorcist letter as being mailed by the Bay Area murderer , rather somebody masquerading as the Zodiac Killer - and here's why. 

What the above document doesn't tell you - is when the S.L.A letter was mailed or postmarked.
The above document read "that on 2/14/74 the enclosed letter was received by the San Francisco Chronicle." Received is not mailed. If we travel a little further in the FBI files we can find more information on the S.L.A letter and envelope, listed under Qc64 and Qc65, as circled in red on the above document.
The FBI files state on more than one occasion:
Qc64 Photocopy of envelope postmarked "U.S. Postal Service, CA 913 PM 3 FEB 1974", bearing the hand printed address "Editor San Francisco Chronicle San Francisco, California".
Qc65 Accompanying photocopy of sheet of paper bearing the hand printed message beginning "Dear Mr. Editor, Did you know that the....."     

It is believed that the Zodiac Killer by mailing the S.L.A letter, was piggybacking the media exposure regarding the kidnapping of Patricia Campbell Hearst, granddaughter of American publishing magnate William Randolph Hearst. "On February 4, 1974, 19-year-old Hearst was kidnapped from her Berkeley, California, apartment. She was beaten and lost consciousness during the abduction. Shots were fired from a machine gun during the incident. An urban guerrilla group called the Symbionese Liberation Army (SLA) claimed responsibility for the abduction". Wikipedia.
​
According to the FBI files above, the S.L.A letter was mailed on or before February 3rd 1974 (postmarked 3 FEB 1974).
Therefore, it was likely mailed one day before the Symbionese Liberation Army kidnapping of Patty Hearst. This means one of four things:
[1] The Zodiac Killer was a member of the S.LA. and was involved in the kidnapping plot. 
[2] The Zodiac Killer didn't belong to the S.L.A, but somehow knew of their plans to kidnap Patty Hearst.​
[3] The Zodiac Killer just got extremely lucky, writing "Dear Mr Editor, Did you know that the initials SLAY spell "sla", an old Norse word meaning "kill". a friend", then mailing the letter on February 3rd 1974, just one day before Patty Hearst was kidnapped by the Symbionese Liberation Army​. In other words, it was sheer coincidence. Or,
[4] The letter was written by the Symbionese Liberation Army and had nothing to do with Zodiac.

If this letter was mailed on February 3rd 1974, the day before the kidnapping, then it is highly likely it was mailed by the American left-wing militant organization ​themselves. Coming just five days after the January 29th 1974 Exorcist letter, in which Kevin Robert Brooks decoded the Asian characters to spell "To Kill", it is yet another amazing coincidence that the author of the S.L.A letter would highlight the word "Kill".   

The emphasis on the word "Kill" at the foot of both letters, within days of one another, leading me to believe they are connected. If the S.LA. letter was penned by the militant Symbionese Liberation Army on or before February 3rd 1974, then a good case can be argued, that they were responsible for the Exorcist letter too.

​S.L.A LETTER NOT ZODIAC - AND HERE IS THE FBI FILE TO PROVE IT

The Zodiac Killer mailed the 'Button' letter and Phillips 66 Map on June 26th 1970 overlaying his crosshairs over Mount Diablo. Just a month later, realizing the clues in the Button letter were insufficient, he gave us the answer in the 'Little List' letter declaring "PS. The Mt. Diablo Code concerns Radians & # inches along the radians". The crosshairs with the bold SFPD = 0 were telling us exactly where he planned to 'set his bomb'. By identifying the location in degrees, using a black, bold circle and coupling it with a 'dig' at the San Francisco Police Department, he was effectively giving us the target and the location. His target was the San Francisco Police Department subtended at an angle of 246 degrees from true north. Bearing in mind his bomb threats were focused in San Francisco, all we had to do was find the police department. How experienced the Zodiac Killer was regarding radians is unknown, but he designed a form of clock face with a directional marker pointing true north and then stated "0 is to be set to Mag.N" (which was approximately 17 degrees in 1970). We don't actually need to know how many radians he intended, from which point, and whether they were meant to travel clockwise or anticlockwise around the clock face, because the bold, dark circle is already the answer.   

On the left I have combined the crosshairs from the 'Button' and 'Little List' letters. The bold, dark circle is 246 degrees around the circumference (which is 4 radians + magnetic north). A radian is 57.3 degrees, so 4 X 57.3 + 17 degrees = 246 degrees. If we deduct 2 radians from true north we get 360 - 114.6 = 245.4 degrees. So, whether we use 2 radians anticlockwise from true north or 4 radians clockwise from magnetic north, the result falls within the circumference of his bold, dark circle (246 and 245.4 degrees). 

Drawing a line through this bold, dark circle from Mount Diablo and across San Francisco, it passes near only one police station, that of Ingleside. It isn't absolutely accurate, but it is the closest police station the measurement relates to. This is why he added SFPD next to the bold, dark circle rather than placing it at the foot of his letter in customary fashion. His bomb was to be set in the vicinity of the San Francisco Police Department at Ingleside. Whether he actually meant it is debatable, but it was the threat that was likely his main goal - sowing more fear into the heart of San Francisco.

The Zodiac Killer made many bomb threats in the 1970s, including references to "black power" in the April 28th 1970 'Dragon' card, along with his Symbionese Liberation Army letter in 1974. This has led some to ponder if the Zodiac Killer was somehow affiliated to a radical group, or possibly infuriated by groups such as the Black Liberation Army or Black Panthers, stealing the limelight away from his dwindling publicity: "I would like to see some nice Zodiac buttons wandering about town. Everyone else has these buttons like, black power, melvin eats bluber, etc". The Zodiac Killer may have been mailing correspondence well into 1971, with communications such as the July 13th 1971 'Monticello' card, 148 character cipher, and quite possibly, the unseen DMV letter. At this period of time, it appeared as though the Zodiac Killer was desperately attempting to connect himself to the murders of Debra Gaye Furlong, Kathy Ann Snoozy and Kathy Bilek, all savagely stabbed in excess of fifty times.   

Mary Alice Willey arrived in San Francisco in 1969, making some questionable alliances, including the black power movement. "She became a strident devotee of George Jackson, the charismatic but militant San Quentin inmate who had gained international fame for his best-selling prison classic, "Soledad Brother." She wrote letters to Black Panther Johnny Spain, who was also incarcerated at San Quentin. And she began associating with members of the Black Liberation Army, a violent offshoot of the Black Panthers that would become implicated in the Aug. 29, 1971, killing of a police officer at San Francisco's Ingleside Station. There is reason to believe that Mary Alice may have played a role in the attack and the slaying of Sgt. John V. Young". Read more at the San Francisco Chronicle. 

While in San Francisco she dated a fellow student, Patrick Warren McDowell, who claimed he belonged to the Symbionese Liberation Army, a group ultimately responsible for the kidnapping of Patty Hearst in 1974. In February 1971 he was arrested for the failed robbery of the Sugar Bowl Ski Lodge near Lake Tahoe, having borrowed Mary Alice Willey's car.

If the Zodiac Killer was still closely following the news in 1971, as it appears he was, regarding Snoozy, Furlong and Bilek, then it wouldn't have gone unnoticed that the Ingleside Police Station he had threatened to bomb just over a year ago, had now come under attack. On August 21st 1971 a gun was smuggled to George Jackson in San Quentin Prison. As Jackson was being escorted back to his jail cell, a guard noticed the gun. Jackson raised the weapon and, paraphrasing Vietnamese revolutionary leader Ho Chi Minh, declared: "This is it, gentlemen. The dragon has come." As he later ran across the prison courtyard, a guard opened fire killing Jackson instantly. 

On August 29th 1971, a woman who bore a resemblance to Mary Ann Willey, wearing a blond wig, entered Ingleside Police Station to report a stolen purse. "Police have long thought the woman who had come to the station to report her stolen purse was a lookout connected to the Black Liberation Army, and they believed that woman was Mary Alice". Chronicle.  A short time later several black men entered the station and murdered John V. Young with a shotgun through the grill of the reception desk. Within two weeks of this attack Mary Alice Willey had vanished. 

On September 11th 1971 a worker stumbled across the body of a woman while driving along the Delta-Mendota Canal in Stanislaus County near Patterson - close to the abduction site of Kathleen Johns on March 22nd 1970. There was no evidence of sexual assault, but she had been stabbed at least 65 times, and her murderer had attempted to sever her fingers and hands. An identification was not made. 

"In March 1970, a pregnant woman and her 10-month-old daughter were abducted near Modesto by a man who drove them around the valley and, according to some police reports, threatened to kill them. Kathleen Johns and her daughter ultimately escaped and hitched a ride to the police station in Patterson. While giving her statement, Johns reportedly saw a drawing of the Zodiac Killer and claimed he was the one who abducted them.

Johns' conflicting statements, though, cast doubt upon whether she had, indeed, encountered and survived the Zodiac. The murder Hedrick is revisiting happened just 18 months after that abduction. The Zodiac claimed 37 kills, though only the five were confirmed. There's nothing to suggest the Zodiac Killer, who never was captured, claimed credit for this murder, sheriff's Detective Marc Nuno said". Read more at The Modesto Bee.

Nearly four decades later, in September 2008, her body was exhumed from Patterson cemetery, and using a forensic sculptor to reconstruct her face and modern DNA testing, she was finally identified as Mary Alice Willey.​

The Zodiac Killer stated in the March 13th 1971 'Los Angeles' letter "I do have to give them credit for stumbling across my riverside activity, but they are only finding the easy ones, there are a hell of a lot more down there". The November 29th 1966 'Confession' letter stated "She is not the first and she will not be the last. I lay awake nights thinking about my next victon. May'be she will be the beautiful blond that babysits near the little store and walks down the dark alley each evening about seven. Maybe she will be the shapely blue eyed brunett that said xxx no when I asked her for a date in high school" and "Beware....I am stalking your girls now". So, in the interest of impartiality, we shall look at a murder in the transition period between Riverside and the emergence of the Zodiac Killer.  

On March 19th 1968 Elizabeth Lurene Ernstein (14) was heading back to her home in Redlands, near San Bernardino from Moore Junior High School in Mentone. The young, brown-haired girl, wearing a blue dress with white flowers, dark olive corduroy reversible coat and tennis shoes was last seen leaving the school at approximately 3:40 pm. The Desert Sun newspaper described her route home: "Elizabeth's school day passed without incident. She attended her last class, then left school at 3:40 pm, to walk home, a two-mile route through blossoming orange groves. She never arrived home. Somewhere along the lonely street, Elizabeth Ernstein vanished. A Redlands businessman thought he saw a girl resembling Elizabeth walking toward the corner of the street on which she lived". 

Her body was discovered in 1969 in a shallow grave near Wrightwood, 33 miles northwest of Redlands (as the crow flies). "Located in a pine covered valley in the San Gabriel Mountains, the area was first developed as cattle ranches in the 19th century by Nathan and Truman Swarthout, then later the main ranch, owned by Sumner Wright was broken up into residential and commercial lots and by the 1920s a community took roots. Early ski enthusiasts discovered the north facing slopes of the San Gabriels above the Swarthout Valley. Until 1937 the ski area, originally known as Big Pines were part of a Los Angeles County Park". Wikipedia. The murderer had clearly chosen a remote location to conceal her body, likely traveling Interstate 215 and 15 from Redlands. 

Elizabeth Ernstein's remains were unidentified until an exhumation in 2011, when DNA was matched to her younger brother, Jeff, finally completing the last but one missing piece of the jigsaw - who was the murderer of Elizabeth Ernstein? There is little, if anything, to connect this to the murder of Cheri Jo Bates in Riverside on October 30th 1966, or the Zodiac Killer, however, it is an unsolved murder in which the family of Elizabeth would undoubtedly like to see resolved. The assumed location of her "vanishing" is situated 13 miles east (as the crow flies) from the alleyway where Cheri Jo Bates was discovered on the Halloween morning of 1966, and occurred 11 months after the Bates letters claiming "there will be more".

Here is an extract from the letter sent by the Riverside City College library staff regarding their favorite 'suspect' Ross Sullivan. The first thing we notice, is that even they admit that police told them Ross Sullivan had an alibi for the time period of Cheri Jo Bates' murder. This clearly wasn't enough for the amateur sleuths of the Riverside City College library (we have to assume the police are just lying) who went on to compile a horrifying list of infractions and suspicious behavior perpetrated by Ross Sullivan. These include:

[1] His "potential for doing harm" - although we have no cited examples of harm inflicted upon any of the library staff. However, what he potentially could have done, is possibly a cause for concern. 
 
[2] Bragged about escaping over the wall from Patton State Mental Hospital, which doesn't equate to being a murderer.

[3] The library staff member stated "I wish I could remember the poem about the cataloging boss he and I both had. I remember that she did not understand the poem he wrote. I didn't either but was frightened by it". Frightened by a poem you neither understand and can't remember, is terrifying enough on its own

[4] "We could see him from the cataloging department. He was like a statue - always there". Clearly he was a menacing statue - not moving - but an ominous presence nevertheless.

5] "When the murder happened, I stated to my fellow workers that when Ross reappeared on campus (because he was not around the day after the murder), and if he had on different clothes, then he would be guilty in my mind, until someone proved him innocent". I really hope this person never sat on a jury. Whatever happened to those good old values of 'innocent until proven guilty'? Whatever happened to 'beyond a reasonable doubt'? I hereby sentence you to 50 years for buying new clothes.

[6] "Sure enough, it was a few weeks before he reappeared at his spot on the pit wall and he had on a totally new set of clothes". Guilty as charged Sir - how dare you wear a different set of clothes after a few weeks.

[7] "One rainy night after he was back in Riverside, I stopped at a liquor store in Market Street. I pulled up alongside a car that was parked just in front of the store doors. I ran inside but left the doors locked as I always do. When I ran back to my car something told me to do a very strange thing. I ran around to the passenger side and in a flash I had the door open and was inside and the door locked behind me. Just at that instant Ross came from a large hedge in front of my car door and walked between the two cars and out of the parking lot. He did not look at me. Needless to say I drove out of there as quickly as possible". This is called historical narrative building - creating a sensationalized and novelistic reconstruction of events that never happened. The person is selling you a story. Using the introduction of "one rainy night" is unnecessary to the story, used for dramatic effect. She just happened to pull up to a liquor store where Ross was hiding behind a bush in the rain, then coincidentally "something told her to do a very strange thing" - get in the wrong door of her vehicle, just before Ross "instantly" emerged from a large bush. What told her to do a very strange thing? - a sixth sense of impending doom, before she raced away fearing for her life. The fact of the matter, is that nothing happened - and if Ross Sullivan was there, he was likely just walking by without even noticing her. Had he glared at her menacingly from his sodden, furrowed brow, with dastardly intent, the story may have been a bit more compelling. Or, if he had he leaped from the bush wielding a dripping axe and mumbling incoherently. 
 
[8] "Ross apparently parked a motorbike close to one of the faculty members car each day during the fall of 1966. That faculty member also put Ross at the top of his list as a suspect in the murder. Didn't apartment residents near the murder site recall hearing a motorbike start up just after the screams". No they didn't, so it is probably advisable to read up on the facts of the murder, before establishing Ross Sullivan at the top of your suspect list - guilty of parking his motorbike close to a car in the parking lot. Was it menacingly close, bordering on threatening? Did it get closer each day, inching to a dramatic conclusion? Was it raining each day?

[9] "There are half dozen or so of us at Riverside City College that agree on a suspect - but it isn't one that the police are interested in". I will probably side with the police on this one, who actually did a proper investigation and stated he had an alibi. On the flip side, the library staff may have a compelling case to bring to court  - Ross Sullivan was smelly, changed his clothes at least once, allegedly hopped from a bush in the rain without an axe, threateningly parked his motorbike in the campus grounds, wrote poems nobody can remember and moved as fast as a statue, apart from when he was vaulting mental hospital walls. In his spare time he murdered five people in the Bay Area, despite the fact nobody can place him within 75 miles of any crime scene. On a rainy night, maybe he rode stealthily into the Bay Area on his old Triumph motorbike four times, placing the executioner's costume in the top box on September 27th 1969 for the return journey to Santa Cruz. Or maybe some evidence would help. 

A pasted card mimicking the '13 Hole' postcard was mailed to the home address of Dr. Edward C. Adams at 102 Camino Don Miguel, Orinda, California, postmarked October 17th 1970 from Berkeley. Edward C. Adams was a psychiatrist. The card read "Mon Oct 12, 1970. Edward Adams. The Zodiac is going to change the way of committing murders. I shall announce when I shall commit my murders, The Adamses are Next. you taught me to mean it. ADAMS YOU ARE NEXT. Zodiac".

Fast forward to July 8th 1974, when another suspected Zodiac correspondence was mailed to Marc Henry Spinelli of the San Francisco Chronicle. He was better known as Count Marco, running an advice column in the paper for 15 years. The only time Zodiac addressed the columnist was in respect to a topic on psychiatrists and psychologists, which featured only five days prior to the July 8th 1974 'Red Phantom' letter. The column, dated July 3rd 1974, began with "When I wrote that psychiatrists and psychologists ruined more marriages than they saved, I wasn't surprised by the angry reaction. I had contended that shrinks look at ordinary marriage problems as "cases," to be dissected, rearranged and deranged, leaving the "patient" totally disoriented. What would happen if a physician examined a patient and said, "You have such and such a disease. Now do something about it," without prescribing treatment. Mother Nature is like an oyster. She heals emotional wounds through passage of time. An oyster finds a grain of sand has forced its way into the shell. As time goes on its mucous continually covers the irritant until eventually what was a sore spot becomes a magnificent pearl. However, if one instead took a sharp instrument and sliced the pearl in half, the only result would be to expose the original grain of sand, the irritant. According to a report in The Chronicle, behavioral researchers have shown unmistakably that psychiatry is a very imprecise tool in diagnosing mental illness".
    
This clearly prompted a response from the author of the 'Red Phantom' letter, who wrote "Editor - Put Marco back in the hell-hole from whence it came - he has a serious psychological disorder - always needs to feel superior. I suggest you refer him to a shrink. Meanwhile, cancel the Count Marco column. Since the Count can write anonymously, so can I - the Red Phantom (red with rage)". Many people have attempted to analyze the Zodiac Killer from a psychological perspective, so is it possible the Zodiac Killer used his knowledge of this subject to play a game with his 'audience', throwing them red herrings throughout his communications? Directing the audience down a path he chose for them.

​"Edward C. Adams spent most of his life in the Bay Area where he attended the University of California Berkeley for his undergraduate work and Stanford University for his medical degree. His residency in psychiatry was received at the Menninger Clinic, Topeka, KS. During the Korean War he was an instructor in the Medical Field Service at Fort Sam Houston, San Antonio, TX. After retiring from an active practice in Psychiatry he devoted his energies to travel, fly fishing, the study of poetry and the enjoyment of his family and many friends. During the time spent at his Carmel home he volunteered as a docent at the Robinson Jeffers Foundation. He was a member of the San Francisco Psychoanalytic Society and an active supporter of many environmental groups".  SFGATE.COM.

One of the addresses for Marc H. Spinelli was 747 Geary Street, San Francisco, the location often associated with where taxicab driver Paul Stine picked up the Zodiac Killer on October 11th 1969. He would be murdered a short time later at the intersection of Washington and Cherry Streets. How well the Zodiac Killer knew this area is subjective, but he may have chosen this area because he was familiar with the surroundings - crucial when planning an escape route from a murder. Had the Zodiac Killer worked or trained, somewhere in or close to Presidio Heights.  

In the FBI document on the right, it is clear that Inspector David Toschi of homicide detail believed the 'You Are Next' card may have been mailed to Edward C. Adams by a former patient of his. However, if the card was mailed by the Zodiac Killer, what connections could he have to Edward C. Adams, his profession, or Orinda, California? 

The crucial phrase in the card is "you taught me to mean it". You don't teach patients, you diagnose them. What if the Zodiac Killer trained as a psychologist, or went to one of Edward C. Adams' seminars or lectures? He could easily have picked up some useful 'psychological advice', used to convince his audience in the guise of the Zodiac Killer - conveying his threats with menace and meaning. In other words, Edward C. Adams "taught him to mean it" under the Zodiac umbrella.

Dr. Edward C. Adams was a member of the San Francisco Psychoanalytic Institute & Society. "The San Francisco Center for Psychoanalysis was organized in 2007, combining the San Francisco Psychoanalytic Institute & Society, founded in 1941, with the San Francisco Foundation for Psychoanalysis, founded in 1991. The Center provides an extensive training program in psychoanalysis. The Center also sponsors a large, vibrant Extension Division which offers classes and seminars to mental health professionals as well as to the general public." link.​ Was the Zodiac Killer sitting in the audience taking a lesson from Edward C. Adams in how "to mean it"? The San Francisco Psychoanalytic Society and Institute is a facility for psychoanalytic research, training, and education located on 2420 Sutter St. in San Francisco, California. It is situated in Lower Pacific Heights, approximately one mile from the intersection of Washington and Cherry.
