I was watching a program the other day and it was the first ever case where DNA was used to tell a suspects ethnicity. We all know this can be done and has been around for a long time. But what I was unaware of, and maybe some here will also be, is that a new DNA test called The 'Hirisplex system' can predict with above 95% accuracy, the Hair and the Eye color of a person just from this form of DNA! First thing I thought of..... "Zodiac!!" If the DNA held by the SFPD is there then they can test it and discover the natural hair color of the Zodiac, as well as his eye color. Nobody ever saw Z's eyes, Hartnell said he had dark glasses on to cover the eye's and Fouke said he remembered seeing his eyes but that it was too dark to discern color. Zodiac put his head down to hide his eyes from Fouke, and wore sunglasses to hide them at Berryessa. Now there is a test that can unmask these features all these years later! Here's a brief outline in a BBC article: www.redorbit.com/news/science/1112681895/dna-test-hair-eye-color-082612/Note that it is stated: "The Hirisplex approach could be very useful in cases where a perpetrator is completely unknown to the authorities, said Kayser. "

This HirisPlex system for DNA analysis is very encouraging!
Even if it doesn’t solve the Zodiac killer mystery, it could be used for other cold cases.

Thanks for sharing the video Ricardo, it explained it much better than what I had seen before.

Hey Rick, Sandy, good to hear from you both.
I know this type of test won't solve this case Rick, but it could go some way in narrowing down the potential suspect field if we knew to a almost scientific certainty that the man who shot Paul Stine on Oct 11 had natural light brown hair with brown eyes and was 95% Caucasian White/5% Native American for example.
Hey sandy, as far as I understand it, the SFPD collected a very small amount of suspect DNA (So they say) and they say the reason the DNA Profile of Suspect was not entered into the National DNA Database was because there needs to be a minimum of 9 markers available within a DNA sample for a genetic profile to be extracted and entered into the database. Anything less is not enough to submit for comparison as there is no enough identifying markers witnin the DNA structure itself. Something like that, anyway. Maybe that's why they never tried this latest test. The again, the above argument as to why they can't do a DNA comparison I would find believable...If we were living in 1998 still. In 2015, we have all sorts of new scientific advances made, mitochondrial DNA and Y-Line DNA, the latter of which can:
"tests the Y chromosome which is passed from father to son, along, in most cases, with the surname. Only men can test for this, because only men have a Y chromosome, leaving female genealogists with Y chromosome envy, having to go and beg off of their fathers, brothers, uncles and male cousins to test for the surnames in question. We compare the results of the Y chromosome test between males to see if they match and are related in a genealogical timeframe. We also obtain the haplogroup which defines deep ancestry, such as European, African, Asian or Native American."

Thanks Zam, That is great news! They will be using two envelopes from the July 31st letters and stamps. I like Terry P but I do not agree with him about Art Allen being the Zodiac and that the DNA that was used to prove he was not the Z, was not good enough to use to eliminate suspects. I spoke to the SFPD Lab Tech years ago, she said what they had was good enough to eliminate, but not enough to convict. I just sent a " I hate to say I told you so" to Tom V. Because he sent a text about the Z DNA news. He and I have argued for years that there is Zodiac DNA! (Feels so good to be right) Thanks again for the new hopeful news Zam!

I was just thinking that if Zodiac reads the news about his DNA being treated the same way as the GSK and that he may be caught. He could get rid of any momentous or evidence.
That is why nothing was said until the arrest was made to catch the GSK. "Loose lips can sink ships" Everyone is talking about it as if he is dead and he is not!

It was just on the TV news this morning. Terry P has no idea what he has done to hamper the case by giving a warning to Zodiac.Mark my words this will bite him in the a--!

Congratulations on your book Mike!
I have argued about the Zodiac DNA for several years now, I am sure you have seen my posts. The 2002 DNA on the outside of the envelope, I believe was done for the "TV show",for show only.
The real DNA that was used to eliminate Art Allen and a few others, was DNA that SFPD got from under the stamp and flap in the 1990's not 2002.
Ricardo and I were told they had Zodiac's DNA, by the tech from SFPD at a zodiac get together we went to. She said it was enough for eliminating but not enough to convict.
VPD has sent in two Aug 31 1969 envelopes for testing and expect the results back this June. I know that your Mr X is dead, my suspect is very much alive, so I am upset VPD has made the announcement before they solve the case. They think Art Allen was Zodiac who is also dead so no worries of him running.
If the Zodiac is alive and I do believe that he is, he will destroy any evidence that could tie him to murders we don't know about.
He could leave the country or commit suicide!
My suspect for instance, has already left the area and has gone to Los Angeles. Not far from the border if he wants to get away. That is what criminals did back in the 60'.
People on Tom's site have posted that Zodiac probably got rid of the evidence long ago, but he thought there wasn't any of his DNA to worry about, because of the people who kept posting there was none. Now he has to be very worried!

I understand that a film crew filmed Mark Hewitt two weeks ago in Vallejo about the Zodiac. It will be shown this coming fall, I am looking forward to seeing it. By then hopefully we will know who Zodiac is? The DNA was said to be back in June, but now it looks like it might take longer for the results. Tom V was back in Vallejo last week and said that VPD has found more boxes of Z evidence! I am still disappointed in how VPD made the announcement that they were sending in more Zodiac DNA samples to try and solve the case. Someone on Tom V's site who I think was a VPD Det. tried to defend the announcement, by saying to me that it was Paul Holes announcement that I should be upset about and not VPD. For Paul Holes to say that now that the GSK case is solved, perhaps we can solve the Zodiac case? That is not like VPD telling the Zodiac look out we are sending more DNA samples in and looking for a match to get you Zodiac! He could destroy any evidence that could link him to other murders he may have committed and Paul Stine's keys ,Wallet, more of his shirt material, his weapons. What the heck were they thinking when they made their "showboat' announcement? They did what they did, not thinking that the Zodiac could still be alive, because they are still stuck on Art Allen as being the Zodiac is what I think. (Having my morning coffee and venting ! )

Congratulations Mike on your book doing so well!
I know that the Zodiac DNA has been like a thorn in you side over the years and is the way most would feel if we went by what we know about the 2002 DNA sample.
But there were samples taken in the "1990's" by Pam Hoffsass, that we are forgetting about. Those were not from the outside of the envelope, they were from under the stamp and the inside flap of the envelope.
Now VPD has sent in two of the three envelopes from the July 31st 1969 letters to be tested, hoping for a full DNA profile.
Those were used to eliminate Art Allen and a few others as being Zodiac, not the 2002 DNA samples, is what I understood Pam Hoffsass to tell us at a meeting in San Francisco.
It seems people have forgotten about the earlier DNA testing? I thought that Bowart had the coroner take samples of Art Allen's DNA and sent it in right away?
Now that we have better DNA technology we could get want is needed to solve the case. I saw on the news just the other night, that Livermore Lawrence Lab Techs are trying a better way than the usual DNA testing which can degrade over time. It is using "proteins" that can last much longer!

Davb2, Sadly there has been a lot of very bad reporting, they know just enough to be dangerous. Most all of them don't know that there were DNA tests done before 2002.
So all they report about is the 2002 very bad swiping of the "outside" of that envelope and stamp. Even I would know better than to do that to get Zodiac's DNA geez !
