Mike Rodelli is convinced that DNA will not solve the Zodiac case because the authenticated letters were not licked by the sender. Mike Rodelli spoke to Alan Keel in 2007, who was a Criminalist at the San Francisco Police Department from 1996 to 1999. He gave Mike Rodelli the following information: "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". According to Mike, Alan Keel had "analyzed two 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".

On October 29th 2021, Mike Rodelli stated on the Zodiac Killer message board "The fact remains that in 2007 Keel told me, as he had told Lafferty before me, that there is a 1974 forgery based on DNA and the ONLY 1974 letter that had been tested for the presence of cells during Keel's tenure (as demonstrated by the DNA chart that I believe Keel made in about 2000) was the Exorcist letter. This is not rocket science.  Even if it is not the Exorcist letter that Keel was talking about, it IS a candidate as being a forgery whose DNA matches the 1978 letter based on the information in the chart".

In his book, The Hunt For Zodiac, he stated "Now there was DNA proof that whoever had penned the April 1978 letter had also penned one of the 1974 letters. And apparently it was not Zodiac. According to the chart of DNA testing results compiled by SFPD's lab in ca. 2000, the only one of the 1974 letters that had been tested by Keel up to that time was the January Exorcist letter. This was the letter that had a swarm of palm prints on it. This created an interesting dilemma that lends credence to the possibility that this is a forged letter. Zodiac had penned a dozen letters prior to writing the Exorcist letter and had never left even a single palm print on them. So why had he suddenly and carelessly taken off his glove(s) to write this one and leave a virtual montage of his palms all over it. From that standpoint alone, it makes sense that someone else may have written the Exorcist letter, its bizarre content notwithstanding. While it is possible that one of the other three letters was tested for DNA subsequent to the compilation of the DNA summary chart that Keel had assembled, I believe that on balance the most likely candidate for being the 1974 forgery is the Exorcist letter until proven otherwise". Mike Rodelli is almost certainly correct that the 1974 Exorcist letter is overwhelmingly the most likely DNA match for the 1978 letter (because it was the only tested in the DNA chart), but here is the almost certain proof that neither the 1974 Exorcist or April 1978 letter were forgeries. 
​
Take a look at the address style, spacing and handwriting of the Exorcist letter envelope (below), and compare it to the two April 1970 communications (in particular the Dragon Card envelope). These two April 1970 envelopes had not been publicly released by 1974. They were the only confirmed Zodiac communications to use the address style of San Fran (dot) Chronicle prior to January 29th 1974. The January 29th 1974 author (if a hoaxer) could never have produced such similarity, or had knowledge of the address style of the April 1970 communications. But the real Zodiac Killer could have. 

​Mike Rodelli is confident that the SLA letter mailed in 1974 was authored by the Zodiac Killer, stating "Envelopes: This is where the rubber truly meets the road in this discussion and where we can see that it is unlikely that anyone but Zodiac wrote the SLA letter. When you look at the hand printing on the SLA letter in a vacuum, it certainly does not jump off the page to me that it was penned by Zodiac. But when you take a close look at the envelope, that is a different story". Mike then gave me a list of envelopes here, to compare with the SLA envelope. If Mike is confident that these comparisons strongly argue for the SLA letter being Zodiac, there is no way he can argue against the Exorcist letter envelope being the same author as the two April 1970 communications (particularly the Dragon Card). If the two April 1970 communications are genuine Zodiac, then so is the Exorcist letter. If the Exorcist letter is genuine, and the argument in favor of the Exorcist letter DNA matching the 1978 letter DNA by Mike Rodelli is correct, then the 1978 letter is genuine too. 

In the link above, Mike Rodelli argued that the writing on the SLA envelope is consistent with the Stine envelope, 340 envelope, Bus Bomb envelope and Kathleen Johns envelope, stating "It's hard to look at these envelopes and not see the similarities. And note that the November 8, 1969 envelope contained a piece of Stine's shirt, thus proving its authorship as being from Zodiac. There it is in black and white. So the evidence seems to show that, regardless of the timing and his reason for being in Los Angeles on February 3, 1974 (assuming that the letter was posted from there on that date), it was, in fact, the Zodiac killer who sent the SLA letter, not the SLA itself, which, once again, would not have benefitted from its contents. Nor is there any reason why they would have benefitted from imitating Zodiac's handwriting on the envelope but not attributing the enclosed later to him".

Again, if Mike Rodelli is claiming these envelope comparisons are good proof the SLA letter is genuine, he now cannot with any good conscience claim that the comparisons between the Exorcist envelope and the two April 1970 envelopes are not equally as good. Especially when the April 28th 1970 envelope had never been released into the public domain for the author of the Exorcist envelope to copy (not only the handwriting, but the format of San Fran (dot) Chronicle). This being the case, Mike Rodelli (based on his statements) must now accept that the Exorcist letter and SLA letter are genuine Zodiac correspondence. Therefore, if Alan Keel is correct and the 1978 letter DNA matches one of the 1974 communications, we are left with the Badlands card or Red Phantom letter for Mike Rodelli to choose from. But this is what happens to the SLA envelope when we add the "tails" from the Red Phantom envelope. Bearing in mind the SLA envelope wasn't available for the author of the Red Phantom envelope to copy, the writing is virtually indistinguishable from one another, along with a single comma and address format. If Mike Rodelli finds "It hard to look at the envelopes he suggested and not see the similarities to the SLA envelope", he cannot fail to see the similarity between the SLA envelope and Red Phantom envelope. If he believes that the SLA letter was authored by the Zodiac Killer, he now must accept (using his arguments) that the Red Phantom letter was authored by the Zodiac Killer as well. Fortunately, in his book he does.    

However, in his book Hunt For the Zodiac, he also makes an extended case for the Badlands letter being the Zodiac Killer, stating "In it (the Badlands letter), the anonymous author is accepted based on hand printing as having once again been Zodiac". So, Mike Rodelli is arguing that the SLA letter, Badlands card and Red Phantom letter are genuine Zodiac, but the Exorcist letter is the one he questions most. But if he accepts the arguments he has given for these communications being authentic Zodiac (including the SLA envelope handwriting), he can only come to the conclusion that the Exorcist letter is genuine too. We can therefore conclude, using Mike Rodelli's own words, that if Alan Keel showed a DNA match between the 1978 letter and one of the 1974 letters (and all the 1974 letters are genuine), then the Zodiac Killer licked the envelopes and stamps on the 1978 letter, Exorcist letter, SLA letter, Badlands card and Red Phantom letter. In other words, he never used tap water. The only way that Mike Rodelli can maintain the claims made at the beginning of this article, is to say the comparisons between the two April 1970 envelopes and the Exorcist envelope are not as valid as the comparisons he has made between the SLA envelope and the four envelopes he listed. In good faith, that argument cannot be made. The reality is, that the Exorcist letter is genuine Zodiac correspondence, and contrary to the arguments Mike Rodelli has made. 

I asked Druzer, a Zodiac researcher who contributes to both Zodiac forums, to send me a series of questions that I could incorporate into the next Zodiac Speaking podcast on June 4th 2022 for Mike Morford to tackle. However, because he devoted a lot of time compiling these questions and there wouldn't be enough time to address them all in the next podcast, I decided to answer the majority of them here myself. ​The topics covered are confined to the four canonical attacks at Lake Herman Road, Blue Rock Springs, Lake Berryessa and Presidio Heights, in respect to the victims and eyewitnesses in the case. Running time: 30m 17s.  

Robert Michael Salem was stabbed seven times and murdered in his 745 Stevenson Street, San Francisco apartment on April 15th 1970. His body was discovered by friends from the nearby San Franciscan Hotel on April 19th 1970 when they realized they hadn't seen Robert Salem for several days. Investigators found a gruesome scene, with the blood of Robert Salem having been used to scrawl the words "Satan Saves" and "Zodiac" on the apartment wall, accompanied by a drawing of the ancient Egyptian ankh symbol. The ankh symbol, as detailed in the newspapers, was also "drawn on Salem's stomach". Whether the symbol on Robert Salem's stomach had been carved into his flesh or "drawn" on by a marker pen cannot be ascertained by this wording alone, but clearly this symbol held some significance to the person who perpetrated this murder (or wanted us to believe it did).

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).

This idea was exacerbated by the Zodiac Killer's use of three circled eights (Jesus in Christian numerology) and the "anchor" symbol  in his April 20th 1970 letter. The word "anchor" has the same phonetic root as the Egyptian "Ankh", and Christians adopted the anchor as a symbol of hope in future existence because the anchor was regarded in ancient times as a symbol of safety. Maybe significant, was the fact the ankh symbol or crux ansata featured twice at the Robert Salem crime scene, which Christians used as a variant for the Christian cross (seen as a representation of the crucifixion of Jesus on a large wooden cross). Bearing in mind the crucifix style design in blood on the wall of Robert Salem, coupled with his unusual injuries, it was important to examine if any correlation between the two existed (no matter how unlikely). 

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.

ROBERT SALEM-A ZODIAC MURDER?
A CONTEMPORARY CODE ON APRIL 20TH 1970
THE ZODIAC KILLER-DRIVEN BY DEVIANCY     
A SATANIC MESSAGE IN CODE? 

All of the Zodiac letters were hand printed up to December 10th 1969, when the Day-By-Day Forecast for Cancer pasted horoscope was mailed to the Sacramento Bee newspaper. This horoscope page contained more information than visible in the versions shown on the internet. The FBI files state The handwritten notations on Q40 in the wording "...Flight 555 SF. 700 P.M. P.M." could not be associated with any of the other questioned material in this case (because it was cursive handwriting and not non-cursive/hand printed). It is noted in this regard that the writing on the other specimens in this matter is hand printed and that the notations on Q40 are very limited.  

​This means that the limited handwriting contained within the message "...Flight 555 SF. 700 P.M. P.M." was redacted from the image we are accustomed to. It appears that the pasted FLT 555 was referring to "Flight 555" after all. Very likely from San Francisco at 7:00PM, according to the sender. Howard Davis of the Zodiac/Manson website, reported that Drew Peterson relayed information about a reporter who found a United Flight 555 that flew from San Francisco to San Diego every Wednesday at 7:30pm, tying in with the "Birds Fly South" pasted text on the Day-By-Day Forecast for Cancer communication. This almost lines up with the notation of  Flight 555 SF. 700 PM (using a viniculum under 00), which was written on the horoscope page (Q40). The mailing date of the Day-By-Day Forecast for Cancer communication and the abduction of Leona Roberts were both on a Wednesday. Howard Davis has toyed with the idea that the Zodiac Killer was giving hints he was more than capable of traveling to San Diego, where on February 4th 1964 at Ocean Beach, Johnny & Joyce Swindle were murdered by a sniper alongside the seafront. Bolinas Lagoon (where Leona Roberts body was found) and San Diego Bay are also both key sites in the Pacific Flyway for migratory birds.

Leona Roberts was abducted from her boyfriend's apartment at 749 Tormey Avenue in Rodeo at approximately 6:00pm on December 10th 1969, and her naked body was found on December 28th 1969 by an elderly man collecting driftwood near Bolinas Lagoon. The coroner estimated she had been alive 10 to 14 days after her abduction, with the sheriff's office stating she had been dead about 10 days. This suggests she was murdered (or had died in captivity) sometime between December 18th and December 24th 1969. Authorities said it was impossible the body could have been dumped into the bay on the east side and floated through the Golden Gate Bridge. The man collecting driftwood discovered Leona Roberts body on a beach near Bolinas Lagoon - so the location was possibly the southeastern section of Stinson Beach or Red Rock Beach (which is slightly lower on the map below). However, Red Rock Beach can only be accessed by a very steep trail from Shoreline Highway, making it a very unlikely deposition site in absence of the body being thrown from the clifftop. Stinson Beach has many houses along its shoreline (even in 1969), so it could be argued that somebody disposing of a dead naked woman at this location, would probably have chosen the southeastern edge of Stinson Beach, which was devoid of residences. But why choose this location at all? 

If the killer had traveled westwards to this location and used Shoreline Highway, there are innumerable turnouts, clifftops and wooded areas before you reach Stinson Beach, near Bolinas Lagoon. In fact, there is in excess of 10 miles of winding road before you reach Stinson Beach, where a body could have been secreted quite easily. So why would you pass all these potential dump sites and place Leona Roberts on an open beach, unless you wanted her found and was making a statement? The same argument can be applied to somebody approaching by vehicle on the northern side of Bolinas Lagoon - unless she had been deposited in the water at a different location and the currents carried her to Stinson Beach (or somewhere nearby).  

​If the estimates of her time of death are fairly accurate, then we have a scenario where a woman is kidnapped, kept alive for 8 to 14 days (18th to 24th December), before being found 4 to 10 days later. It is highly unlikely her dead body had been on Stinson Beach, unnoticed for several days. So had it washed up recently, or had the killer dumped the body on the beach shortly before it was found, having stored it for several days?  There are two viable options: either she was deliberately placed on a beach somewhere near Bolinas Lagoon by her killer, or she was thrown into the water at a secondary location and was carried by the currents to the location she was found on December 28th 1969.

Associated articles: A Very Unlikely Zodiac Murder and Did Zodiac Call on January 4th 1970?

Steph 54: On 28 December 1969, a man searching for driftwood on the beach at Bolinas Lagoon in Marin County found the nude body of Leona Roberts. It was later determined that a unique wristwatch was missing from the girl's wrist, but a Napa High School class ring given to her by a neighbor still remained on her finger. The tan dress she wore when last seen, along with two pairs of bell-bottomed pants, a blouse, a black purse and wallet, a key chain with car and house keys were also reported missing. There were marks on the wrists and ankles indicative of binding, but the coroner was unsure whether they occurred before or after death. The cause of death was reported as "due to viral infection of an unidentified species." It was also reported that there was "evidence of choking which could probably be linked to the virus." The coroner estimated that she had been dead 4-7 days (December 21-24) prior to recovery, and he theorized that she had been alive 10-14 days after her abduction. Articles reported the coroner's theory that Leona had been kept bound for a period of time, died as a result of the viral infection, and was disposed of by her abductor(s). Pathological and toxicological tests did not find any drugs or alcohol in her system.

Leona Roberts was abducted on December 10th 1969, in tandem with a communication of pasted words that contained "Zodiac", "Watch" and "Birds Fly South". This communication, eighteen days in advance of her body being discovered, highlighted the word "Watch" in the largest letters, and significant bearing in mind a unique wristwatch was reported missing from the girl's wrist on December 28th 1969. She was also found at Bolinas Lagoon, so the "Birds Fly South" phrase may have some meaning when we consider that Bolinas Lagoon is a major north-south Pacific flyway for migratory birds in America, extending from Alaska to Patagonia. 

​The coroner also noted marks on her wrists and ankles, suggestive of somebody being bound. The two sinister communications on December 10th and 11th - obviously mailed by the same author - were horoscope forecasts, with the second communication possibly a play on words using the name of Leona Roberts. It was entitled  Day-By-Day Forecast For Leo. The fact that this author facilitated the use of forecasts in accompaniment to the word "Leo", when her body took eighteen days to surface, with the coroner estimating her death 10 to 14 days after her abduction, is some forecast. ​

The Zodiac Killer had claimed seven victims on November 9th 1969, but he didn't (assuming it was Zodiac) raise this victim count in the two forecast letters on December 10/11. He also made no change to his victim count in the two Fairfield letters mailed on December 7th and 16th. Yet he did raise his victim count to 8 on December 20th 1969, when he stated "I am afraid I will loose control again and take my nineth & possibly tenth victom". This could imply the Zodiac Killer claimed his eighth victim between December 16th and December 20th 1969 - very close to the estimated time of death of Leona Roberts. The estimation of death with increased time is obviously more difficult to pinpoint, so it's perfectly feasible an error of just one or two days, places her time of death between the period Zodiac's victim count increased to eight. The two forecast letters were never publicly released at the time, making the threatening "Zodiac" phone call to Peggy Trainer (18) on January 4th 1970, who lived in the same building from where Leona Roberts was abducted, a further uncanny coincidence.   

The Zodiac Killer claimed the Snoozy & Furlong murders in his Dripping Pen card on November 8th 1969, before going on to write a letter to the San Jose Police Department on November 21st 1969, and making a phone call to the San Jose Highway Patrol on December 19th 1969. This was likely done to cement the notion in investigators minds of his involvement in the Snoozy & Furlong murders in San Jose, despite the fact he had no hand in their demise. 

Leona Roberts (16) disappeared from her boyfriend's apartment at 749 Tormey Avenue in Rodeo at around 6:00pm on December 10th 1969. Her disappearance coincided with a pasted communication on the same date from Sacramento, dubbed the Day-By-Day Forecast for Cancer, which contained the pasted word "Zodiac". The following day, on December 11th 1969, a second pasted communication postmarked San Francisco and dubbed the Day-By-Day Forecast for Leo, could have been a play on "Leona" Roberts name and fate, bearing in mind she wasn't murdered for at least a week after her abduction. Her body was found at Bolinas Lagoon on December 28th 1969.

These two pasted horoscope communications were not publicly released, yet somebody claiming to be the Zodiac Killer just happened to phone Peggy Trainer (18) and claim she would be his next victim. Peggy Trainer lived directly behind the apartment where Leona Roberts disappeared from, in the same multi-dwelling residence at 749 Tormey Avenue.

Therefore, we have two sinister horoscope communications on December 10th and 11th containing the pseudonym "Zodiac" and the "Forecast for Leo", along with a potential "Zodiac" phone call to Peggy Trainer on January 4th 1970, who was a neighbor to the apartment where Leona Roberts was last seen alive. Did the person who rang Peggy Trainer claiming to be Zodiac, if different from the author of the December 10/11 communications, just get lucky attaching the pseudonym "Zodiac" close to an abduction site, that coincided with a "Zodiac" communication mailed on Leona Roberts abduction date? Or were the communications and caller the same person, separated by 24 days? 

Thank you to Gavin Fish from True Crime on Youtube for supplying me with this newspaper article from the Contra Costa Times, dated January 7th 1970. 

The point was made in an earlier article that 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 was argued as being 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 was 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? This writing was accompanied by an Egyptian ankh, adopted by Coptic Christians as early as AD 200. If the 13-Symbol cipher was based on the murder of Robert Salem, one could argue that the writing on the apartment wall, along with the murder of Robert Salem, may have featured in this extremely short code.  

The only other time the Zodiac Killer mailed a cipher in connection with a brutal knife murder, was when he mailed the 148 character cipher shortly after the arrest and interrogation of Karl Francis Werner for the murders of Kathie Snoozy, Debra Furlong and Kathy Bilek on August 3rd 1969 and April 11th 1971. In the 148 character cipher the Zodiac Killer encrypted "I will skin three little kids and make a suit from the skin", and wrote "I will send a patch of human skin if their is some left over" in the message of the accompanying letter. Bearing in mind the killer removed Robert Salem's left ear and took it from the crime scene, I considered the possibility that the word "skin" may feature in the 13-Symbol cipher, alongside the word "satan" (or an extension of it), taken from the apartment wall. In other words, the encrypted message was related to the murder scene of Robert Salem. The dash after "My name is" in the April 20th 1970 letter, being the withheld name, with the 13-Symbol cipher being the message.
