I’ve had a bit of a think and my opinion is simply the following:
Nancy’s case and logically those committed in similar time, location and fashion are unrelated to the Zodiac by way of DNA evidence, the only saving grace is if blood found at the scene were planted by the killer or Zodiac or some other unforeseeable allowing for plausibility.
Now If the Sacramento rumor is true then from what crime or what (letter?) does this originate from?
The blood found at the Sacramento crime scene was from the killer slicing his hand while stabbing Nancy, it was not a spot of blood that was "planted" by the killer. Detectives are not stupid people, they can tell when something looks planted, or if it is left by a bleeding suspect leaving the scene.
Blood drops that are left by someone who has a deep cut on his hand, leaves spots that have what is called "fingers" , those "fingers" point in the direction the cut person is walking. That is also how they knew the killer left the same way he got in, through the sliding glass door.

I’ve said it before but the Bennallack case could be the key to solving this entire case. If that blood from the crime scene is Zodiac’s then it’s the most DNA LE have from him, by a country mile.
Answer from a chemist and cell biologist. https://www.quora.com/How-long-does-DNA-last-on-blood
"DNA is usually found in blood, the connective tissue, in the nuclei and mitochondria of cells. There, it is very stable and lasts the life of the cell and then some. DNA from damaged cells is rapidly degraded, as are other components of damaged cells such as proteins. I assume you are more interested in DNA from blood for forensic analysis. As cells die, they begin to degrade and release enzymes which destroy all cell components. In addition, decay from organisms such as bacteria break down DNA. If you have ever seen a molecular biology paper and noticed a DNA gel digested with EcoR1, it is a specific bacterial DNAase from E. coli. The longer DNA is exposed to this type of environment, the more it degrades. If, on the other hand, cells remain intact, at reduced temperatures or frozen, or are otherwise protected from degradation, DNA may last many years with small amounts of degradation. The interior of teeth is an example and would last much longer than blood. That said, with modern techniques like PCR, only a few cells are needed to get good sequence results. You can certainly get DNA from blood samples from crimes tens of years old, if they are stored properly. On the other hand, the Jurassic Park scenario (mosquito bites dinosaur and is trapped in amber) is much less likely to give good results."
As with the Zodiac letter envelopes, it depends on how well the Bennallack crime scene evidence has been stored.
The textbook answer is that preservation and storage is vital — the real life answer seems to be that DNA is a crapshoot.
Sure, that would be helpful to solve the Bennallack case. Same with the SR Hitchhiker. Unlikely they were Z crimes, but if you get a named suspect you never know what that could lead to. They’ve reportedly had DNA from the Bennallack crime though for a couple years at least.
Am I wrong or does this rule out DeAngelo for the possible Zodiac cases in Sacramento? Surely there would have been a DNA match by now.
That’s a good question. If they’ve developed a profile from the Bennallack case, they would be able to either connect or eliminate DeAngelo.
If he was connected, there definitely would have been an announcement.
It’s conceivable they have a profile, that DeAngelo didn’t match it, and that so far they’ve come up empty in matching it to anyone, period.
My guess though is they don’t have a profile.
Regarding my own question, the Sacramento cases were before DeAngelo started (as far as we know) as the Visilia Ransacker. So he would have committed these home invasion murders (without raping victims), then progressed to simply burglarizing homes, then committing home invasions to rape victims, then once again home invasions with murder and also rape. Which all seems unusual.
I didn’t attack you, I just asked about it. And if you look back through that thread, I told you from the start you might have been mistaken and your grandfather might have just been interested in the Zodiac case.
I remember that. You were obviously right and yes it was my fault thinking otherwise. I’d like to try to be as involved as possible on this forum if that’s ok with everyone. I’ve seen people talking about a Sacramento case? Any more info on that?

Answer to your question, as far as I know there is no new information about the Sacramento case as of yet.
Personally , I believe that Zodiac did have some interest in that area, because of the DMV letter possibly being written by Zodiac and other murders in or near that area.
None of those murders were like DeAngelo’s MO, for those who are thinking it could have been him.
We still don’t know everything about the Zodiac’s MO , because he changed it so often to confuse the police, is what I am guessing? ( He seemed to be fulfilling his sick fantasies) When just shooting people no longer gave him satisfaction , he started using a knife again. I say again, because I have my own reason to believe he killed Cheri Jo Bates. August of 1969 Manson stole some of Zodiac’s thunder , Zodiac wanted to do something more that would shock people, like what he did at Lake Berryessa.

Sure, no problem man. Zodiac is a rabbit hole that will suck you in and keep you guessing. Sounds like it did it to your grandpa and it’s getting you to. That just shows how long this has been going on. Welcome to the club. The more people looking and asking questions the better. Hopefully something one of us turns up helps find the SOB who did this.

Nah, we don’t even know if the rumor about Sacramento has any truth to it. I mean, we know they had blood evidence but we don’t know if it actually has anything to do with Zodiac. Like Sandy though, many of us have long suspected Zodiac killed more than the 4 known attacks and the Sacramento cases have long been suspected of being the work of Zodiac, so it makes sense in those terms that the rumors have some truth to them.

Per news report…
‘The suspect cut himself during the assault, Links said. Deputies have a DNA profile on the person who killed Bennallack and the DNA has been in the state and national databases for years."

Surely they must have thought of putting the blood DNA through GEDmatch to go for the DeAngelo capture method.
I don’t want to insult LE intelligence by suggesting they didn’t start that process a while ago.
What happens with these cold cases, is the newer ones take up the time we would like for the very cold ones, that doesn’t always happen as fast as we would like. They can only work when time permits. It isn’t that they don’t want to solve these cold cases.
Bringing her case up and all the attention she is getting, can’t hurt.

This is true, LE simply have to prioritize so the oldest cases get limited time and resources.
I am hopeful that Sacramento will act in conjunction with Vallejo to cross reference their DNA profiles.

Yes, as I said, we know they have blood evidence we just don’t know if it has any association with Zodiac.
There must be something that we have not been told, that gives them reason to think there could be a connection, besides the timing of receiving of the Oct 27th 1970 letter.
It normally takes two days to receive a letter, so that means that letter was more than likely mailed on the day she was murdered. Certain things are kept secret for the detectives in these cases, we don’t know if they also received a call, or if a note was left?
Zodiac liked to brag or leave a clue to his accomplishments. We don’t know if more than just the killers DNA was left there. The DNA has been in the data base for years, so who ever did it ,has not been arrested for any crime that would get his DNA.
Who ever did it could still be out there! I wish they would enter it into something like GED match and solve it that way, instead of waiting for it to solve itself. There could be something being done, between Sacramento and Vallejo, we just don’t know about it?
Where there is smoke there is fire!

Apologies in advance if I’m misunderstanding your point, but the postmark of Tuesday, October 27 would have likely (in 1970) been delivered in San Francisco on Wednesday the 28th. Back then all the local postmarks would have been cleared each night for delivery the next day. It’s postmarked in San Francisco going to San Francisco. One thing I’d be curious to know is if San Francisco did the cancellations for all the surrounding areas back then. If that was true the letter could have been mailed anywhere in the area of that processing facility. But if it wasn’t (and back then outlying offices still did most of their own cancellations) it would narrow the letter down to having most likely been mailed from somewhere in San Francisco. Too bad he or she didn’t just hand the letter over the counter in a post office and have gotten a branch cancellation which would define the area of origin even more.
I’ve always thought the letter to Avery was a clue and a sick joke. Zodiac used, for the most part a set of stamps which were available singularly but at the time were also sold as a combination from part of a book of stamps. You can see the stamps used looking at the envelopes on the confirmed letters. One time I added up all the stamps from verified Zodiac letters and they would have amounted to (from memory) a little more or less than one book’s worth. In any case, the killer departs from using these stamps in the Avery letter using the Apollo 8 stamp (earth seen from the moon) which is captioned "In the beginning….". Apollo 8 was launched early on December 21, 1968. The Lake Herman Road murders occurred late on the night of December 20, 1968 (hours earlier). I think Zodiac was telling Avery he was wrong about the Riverside murder of Cheri Jo Bates and that Farraday and Jensen were the first murders he committed, "In the beginning". It was also blasphemous as he would be placing himself in an exalted position in that context.
In any case, I hope that answers the question about how long the letter would have taken to arrive.
