So, once again, I will show how Mike Rodelli's claims fail to make any sense using his words only. I won't argue against his claims, because he will argue against himself. This is a recent post he made on the Tapatalk forum when responding to contributor Bolt: "You're missing the point. In 1998 using very primitive techniques from that time, Keel was reportedly able to isolate DNA from the two forgeries that matched each other. At the same time, he was unable to obtain any DNA from over a dozen Z letters. Later, using PCR, Holt was STILL unable to develop any "Zodiac DNA" from the killer from the stamps/envelopes, so she resorted to the FRONT of a contaminated stamp just to get any DNA to give to ABC to use to screw me and two other amateurs on national TV. But that is another story. And now you are hoping that there are "two cells" on these letters that will solve the case. Why haven't they been able to find ANY DNA from the Zodiac in twenty years when Keel was able to find it on the two "forgeries" as far back as 1998? I wish I could get Keel to address these questions personally but he is not talking so far".
Mike Rodelli begins with the premise that "two forgeries matched each other" because he has already drawn the conclusion that the 1978 letter is not from the Zodiac Killer. He then correctly makes the observation that the 1974 letter that matched the 1978 letter had to be the Exorcist letter, stating on October 29th 2021 "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". The fact that Mike Rodelli believes the SLA, Badlands and Red Phantom communications are from the Zodiac Killer, should leave you in no doubt that he believes that a DNA match exists between the 1978 letter and Exorcist letter - and because he has already concluded that the 1978 letter is a forgery, then the Exorcist letter must be a forgery too.
What has been presented here, shows that the claims of Mike Rodelli are completely backwards. His own words have effectively argued the case that the Zodiac Killer licked both the Exorcist and 1978 letters, by making statements such as "In 1998 using very primitive techniques from that time, Keel was reportedly able to isolate DNA from the two forgeries that matched each other". The notion that the 1978 and Exorcist letters were those forgeries has been completely dismantled. If Alan Keel found a DNA match between the 1978 letter and the Exorcist letter, he found a complete DNA profile of two genuine Zodiac Killer letters and the Zodiac Killer himself. But will Mike Rodelli now reverse course, realize he has made a grave mistake, and correct these errors? He has written two books and made countless forum posts and videos pushing this narrative - so the answer is no. The consequences of abandoning this narrative will come at too great a cost. The most disheartening aspect of this whole story, is the inability of the Tapatalk forum members to recognise a claim that holds no (tap) water, when that claim is destroyed by the very person making it.
