 Here is a post by Tracers in regards to Stewart, EVB, and DNA.  Anyone who has posted in regards to EVB, please feel free to copy and paste or reiterate from the other thread.

On the DarkSideRadio show tonight, Stewart and the host kept saying how they hope SFPD will step up and compare the DNA so they can see once and for all if there is a match. Even if you believe the partial profile SFPD has is reliable and is from the Zodiac, it can only be used to exclude or include. It cannot be used to make a match to anyone. So why is Stewart going around saying a making a match (and solving the case once and for all) is possible if SFPD cooperates?

It is my opinion that the DNA aspect in this case offers nothing. Even with the slim chance that there was a match, it would not prove guilt. The sample, as I understand, comes from saliva on the back of a stamp and a possible hair captured by the stamp. Doesn't prove murder. Doesn't even prove that the individual that licked the stamp wrote the letter. In turn, it would only disprove that an individual did not lick the stamp. So it's actually a moot point and would never fly in a court of law.

Excellent point. This is what we currently have. A collection of fingerprints, none of which match from one crime scene to another, or to a letter.
Probably a collection of partial and degraded DNA. A tremendous amount of handwriting samples, which the writer could have disguised from his writing.
Questionable ballistics, including the .22 ever being able to be identified according to Police Reports. Eyewitness descriptions which are proven scientifically
to be shaky. Anyone who has seriously studied the case can know this. And then present whomever they like as the Zodiac Killer, knowing there is no way
to disprove it. I suppose Law Enforcement intends to work backwards on this? Hope some suspect will happen to match some fingerprint, or some of the DNA?
Up to this point in time it would appear that the Zodiac Killer was brilliant and crack proof. Oh and those darn ciphers...

Yes, agree. When you break this case down there are only a few facts that are known to be true.

1. A number of people where killed in California during a certain period of time.
2. Some person or persons wrote letters claiming responsibility.
(There is no proof or evidence that these murders were commited by the same person.)
3. No one has been arrested for the crimes.

Everything else is pure speculation. Every book, website, thread and post ever written... Pure speculation.

How can you say there is no evidence showing these murders were committed by the same person? The letters contain info that according to the police, only the killer would know about Blue Rock Springs and Lake Herman. The handwriting on these letters matches the car door at Lake Berryessa. The handwriting on these letters matches the Stine letter, in which the killer enclosed a swatch of bloody shirt belonging to his victim, Paul Stine.  That sure seems like evidence to me.

To my knowledge there is no proof that the 5(+) murders, collectively associated to an entity called zodiac were in fact perpetrated by the same individual.

As to the handwriting analysis; I've never seen where a recognised HW expert submitted expert opinions that the collective Zodiac documents "matched", ie were concluded to have been written by the same person.

Maybe I missed that and stand corrected if that is indeed the case.

Hi-

Mitochondria are known as the cell's "power houses". They contain the mechanism of the Krebs Cycle (Citric Acid Cycle) that produces ATP for the body to utilize for energy. Mitochondria are believed to have been free living bacteria billions of years ago. Now they are found in cells. Since they once were free living organisms, they have their own DNA. Sperm do not have mitochondria; they are only found in eggs. That is why mt-DNA is inherited from the mother not the father.

DNA from the nuclei of cells is only found in the root bulb of a hair. If the hair is cut or torn or breaks off without the root, it can only be analyzed for mt-DNA because the cornification process essentially obliterates the nuclei. It is more difficult to make an exact match with such DNA. Given the restrictions on the ability of a lab to analyze hair for mt-DNA, the presumed letter writer has been very lucky that the hair behind the stamp is only a few millimeters long. Were the lab able to analyze DNA from such a small sample, they might have a much more intriguing DNA profile (mt-DNA) than the 2002 sample is.

I just spoke to a mt-DNA tech and she said that a small hair like that one can be analyzed today but it is hit or miss. It is just as likely that you will develop nothing as it is that you will develop a mt-DNa sample. The real question the lab has to consider is if you wait 10 years, will the technology become such that it is a slap dunk that you will get the DNA out of the hair?

Please point out the BS.

My point is that DNA will not solve this case. It will not convict nor exonerate anyone.
