ZODIAC KILLER SERIES ON THE HISTORY CHANNEL

10/30/2017

 
Picture
The History Channel series about the Zodiac Killer will begin on Tuesday November 14th 2017 and run for five consecutive weeks, examining certain aspects of the Zodiac case, promising new findings on the ciphers and more.

The images on the right are of Cheri Jo Bates' trousers being tested in the laboratory and the crime scene photograph taken in the Riverside City College campus alleyway on October 31st 1966. The promotion attached to the upper image states "AISOCC Review Board Member Suzanna Ryan, Sal LaBarbera and Detective Kenneth Mains used the M-Vac System to extract DNA from clothing of a potential Zodiac victim at our AISOCC Laboratory. What they found after 50 years is shocking....tune into the History Channel on November 14th at 10.00 pm Eastern Standard Time to find out more...."
​

Suzanna Ryan specializes in forensic serology and DNA analysis, with over 15 years experience in the field. Forensic serology is the detection, classification and study of various bodily fluids such as blood, semen, fecal matter and perspiration, and their relationship to a crime scene. The M-Vac system is used in such instances when a victim (in our case Cheri Jo Bates) has been grabbed or manhandled, and the perpetrator has left touch DNA, invisible to the naked eye. The M-Vac system is capable of extracting the touch DNA and so enable the laboratory to generate a genetic profile of the suspect. It uses a wet vacuum system in which a buffer will be sprayed onto the trousers, while at the same time the freed particles will be sucked into a collection bottle for testing. It is used when other techniques have failed, such as swabbing and taping. The samples collected may be incredibly small, so polymerase chain reaction (PCR) is often used to amplify the sample. The sample could be semen, skin cells, saliva or blood. "The M-Vac was able to collect anywhere from 36% to 189% more DNA from experimental evidence items such as extremely dilute blood (1:5000 – 1:25,000) on shirts, rocks, and wood and from touch DNA on knit caps and duct tape". Ryan Forensic. 

Since 2002, when Cydne Holt claimed to have secured a partial DNA profile of the Zodiac Killer from communications mailed by the killer, the field of forensic DNA analysis has come a long way, including the detection and examination of the male Y-chromosome in mixed samples. "The Y chromosome DNA testing enables examination of the male-specific portion of biological evidence. This capability can be especially important in situations where a small amount of male DNA may be recovered in the presence of excess female DNA, such as in sexual assault evidence". link.   

PictureThe Hunt for the Zodiac Killer- begins November 14th
​This is particularly relevant in the case of Cheri Jo Bates, where small traces of male DNA may be present in the mixed sample on her trousers, which were inevitably laden with her own blood after the savage knife attack in 1966. The murderer of Cheri Jo Bates could easily have cut himself while inflicting the numerous injuries on the young woman, either from his hand slipping down the knife as it became soaked with blood, or quite possibly from the knife folding in on itself, had it broke or malfunctioned. The author of the Confession letter did state "I plunged the knife into her and it broke. I then finished the job by cutting her throat". Clearly no knife blade was recovered at autopsy or on the alleyway floor, so if the author of the Confession letter was truthful, it is most likely the killer had a small-bladed pocket knife which could easily have closed onto his fingers or hand, secreting blood onto the clothes of Cheri Jo Bates. 

The promotion material promises "what they found after 50 years is shocking". So, if the hype is to be believed, we would have to assume that the M-Vac system possibly retrieved incriminating DNA evidence, likely from the trousers of Cheri Jo Bates, although one would expect her upper garments are the more likely area to have contained the fingerprint of the killer. However, touch DNA samples can produce erroneous and misleading results, the sample being so incredibly small, it is extremely susceptible  to contamination. Hope you enjoy the series.

I believe you will find that these crimes were done by two separate individuals...

I too believe that Kevin. I am also inclined to believe that none of the communications in this case- the Desktop Poem, Confession letter and Bates letters had anything to do with Zodiac.

*In the above statement I am referring to the Bates crime and the Zodiac crimes... Serial Killers "DO NOT" usually deescalate in their crimes... They in fact usually escalate as they become more comfortable in their craft... The Bates crime was personal and vicious while the Zodiac crimes were assassinations!

Agreed. I think Cheri Bates was killed by an old boyfriend. Edward Wayne Edwards probably contacted the newspaper and tried to point to Frank Dryman in order to frame him for the Zodiac killings. But Frank Dryman wasn't out. Maybe he made parole like Edwards did, but Frank Dryman wasn't out yet. I also want to remind people that serial killers don't wait until their golden years to start killing people. Edwards was convicted of five murders in his later years. So no, he wasn't really a reformed criminal as he was touted to be.

One thing that investigators HAVE NOT talked about is Kane and Sullivan BOTH working in concert with one another. Serial killers have worked in pairs before so, The Zodiac killer could actually be BOTH men. In a most recent episode of The Zodiac Killer, it was found that the ZK may have had a victim in Albany, N.Y. and that both of these men had ties to that area and both men were known to the northern California area where those victims were found . Kane worked in the same office building as Donna Lass a missing registered nurse in California that is thought to be one of the ZK's victims. In Albany N.Y., a letter from the ZK said that he would kidnap and kill a female hospital employee at a certain time/day. What if both of these men met at a .Encryption Society made up of cryptology enthusiasts as mentioned in the History Channel show and they found that they both had common ground in killing and cryptology? This observation needs to be looked at much much closer.

The problem with finding small samples of male DNA on the trousers, is dependent on the source of the DNA. Skin cells could have been transferred to her trousers any number of different ways, not necessarily sinister ones. The same could be said of saliva and fecal matter. For the results to be "shocking" and significant, if indeed they are referring to the trousers, then it would likely have to be something incriminating, such as blood or semen. But we still have yet to pin down her activities in the missing 4 hours, in which any number of things may have transpired, even of a sexual nature, but independent to the actual murder. I may be ultimately proved wide of the mark, but I can't help thinking blood from the perpetrator was discovered on both her upper and lower garments.

The police have his DNA. I told you they are hiding and protecting him. I'm being stonewalled. I have survived the Zodiac case but people don't care because they are eggo maniacs too. The real zodiac is The Spirit Carrier hence his own comment about this thing inside him he said he couldn't control. You won't listen to the truth.

51 years ago, Joe Bates lost his girl to a predator who openly stated, "I am stalking your girls now." Made it clear he wasnt interested in hunting males..

Just a question,to ask you,or any readers that might know.

I believe that LE hold a fingerprint of ''a believed'' Zodiac's right index finger,showing a significant scar.

Can you confirm this,and if so,do you know which crime scene or correspondence,the fingerprint,was lifted from ?

If anyone can help with this question,it would be appreciated.

Richard

Yes, it was from the Stine taxicab.

I was living in San Mateo as a kid when i was down town 3rd ave being a kid. I was outside a pizza joint and bumped into a guy maybe 30 or so wearing blue jeans and a army jacket with long hair and a beard and he looked at me and said i am the scorpion killer and i better leave. I will never forget that as long as I live, I can still see him in my memory.

That is an interesting story,Kelly.And I presume that you are actually referring to ''Scorpio'',the serial killer and extortionist,that was the adversary of ''Dirty Harry'',based on The Zodiac Killer.

For many,across the Western World,and outside of Northern California,the stories of ''Dirty Harry'' were part of their popular culture:not having a clue that they were based on real events that unfolded,in the San Francisco vicinity,!968-1974.

When I first watched the Fincher film,I thought it was the work of fiction !

The folklore surrounding the reality of case,now,has to a certain extent,overtaken the events of fifty years ago.

Its attraction is,because it appears to be,much stranger than fiction [?].

His very name ''The Zodiac Killer'',sounds so alien.If I refer to him,to folk that take no interest in True Crime,I feel almost embarrassed.

I could be talking about ''The Scarlet Pimpernel'' or ''Batman'',for all they know,or really care.

I think LE has two prints, one from the cab and another from the phone booth in Napa. According to a another documentary, palm prints were lifted from a Z letter as well, and this was one step to more or less eliminate Allen. The History Channel also mentions that the new show will explore the 340 cipher. I believe the 340 cipher was a phony code and there is no solution; just an arrangement of symbols to keep the public guessing. It worked.

I believe I may have cracked the first half of the unsolved cipher several years ago. Looking forward to the new series, maybe see how close I got. Should be very interesting.

As the History Channel series nears its first airing,more information is becoming apparent.

We are apparently to be subjected to a ''Code team'',of experts whom,will be displaying some ''nifty'',and on the spot cipher solving.

Two of the team are well known to the Zodiac website community.A third,not unknown,is in the process of promoting a new book.

The ''Code team'',have been allocated a studio with props,made up to resemble a sort of ''Brave new world'' control centre: a hub of electronic and human activity,solving Zodiac's ciphers,while retired policemen are out ''in the field'' looking for further clues.

It all sounds fascinating stuff,and I for one,can't wait to see for what use,precisely,are tracker dogs and helicopters,employed.

Mr.Trump was right,all along.This is the age of ''Fake News''.

I think the first cipher challenge Karmel was given came up as a 'mirror image'. Maybe the way the killer intended to confuse or to make you think it's complicated. And it might just be that simple.
