Zodiac DNA being worked on by SFPD & VALLEJO PD

[sandy betts]

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.

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."

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.

I've always been a bit confused by the timing of the letters. Is it possible to determine exactly WHEN they were dropped in the mailboxes based on the postmark and the date of receipt?

ETA: Sorry for de-railing the thread with an off-topic.

[texas21]

You would not know which box they were deposited in but you would generally know it would be within 24 hours of the cancellation mark as the boxes are scheduled for daily collection on weekdays. Interesting that some of these had Sunday collection postmarks. Don't know how common that would have been in those days. Probably more so than today. Either way, a lot fewer boxes would have been picked up on Sunday.

So no in office cancellations in that time period?

There is a mailbox thread for this discussion. Not directed to Chaucer or the rest. Just thinking that I thought you guys were past this talk.
