Does Zodiac ever take credit for the crime at Lake Berryessa? I’ve read the letters where he gives details about LHR, BRS, and Paul Stine but I can’t find anything definitive on Lake Berryessa.

Yes and no texas. No in the sense that, as you note, he didn’t make any reference to it afterwards in communications. Unless there’s something about it in the 340. He did however take credit for it at the scene with the time, date and weapon used included along with the other murder dates and signed with his symbol ob the car door. So maybe he felt nothing more was needed because this was his proof that he was there.

He also called in after the Berryessa attack,although he didnt say ‘this is the zodiac’ when he called.

I’m a total dork, lol! I didn’t take the car door and phone call into consideration even though I knew about both of them. I was so into the letters that I forgot about those key pieces. Thanks for the reminder.

That’s not dorky, EoT, it’s important!!
Of the five canonical crimes Berryessa is the only one that he doesn’t mention again in any further correspondence, even though we absolutely know he was right there writing on the door, and with the time to stooge around doing anything he liked.
Could that be because Berryessa is the one where he thinks he’s left some evidence, something that gives him away?
It’s got a nice lot of physical evidence, with bootprints, tire tracks and the rest to think about, after all.

I wonder if Hartnell mentioned to Zodiac that he felt he had heard his voice somwere before, as he told the detectives?
Hartnell have said that there was some parts of the communication with Zodiac that he could not remember.

This is what Hartnell said in an interview with detectives September 28, 1969, the day after the attack:

http://www.zodiackiller.com/HartnellInterview4.html

"His voice…I can remember…almost like I’d heard it before.
You know there’s some drawls that a lot of people have simelar.
And…almost as if Id heard it before… couldn’t think where."

So IF Hartnell had mentioned to Zodiac that he felt he had heard his voice somwere before,
maybe that made Zodiac nervous about the LB attack?
Maybe Zodiac was nervous Hartnell at some point would be able to remember where he had heard his voice before?

Here are some different additional info, i found in my files, on Zodiac’s voice related to the Lake Berryessa Attack:

Hartnell’s description of the voice: Remarkably calm voice. Not high pitched or low pitched. The most monotone voice he’d ever heard. Had a drawl, not a Southern drawl, though. Even words, soft spoken. He had a pronounced way of saying things.
Kathleen Johns, "he spoke very precisely.

Hartnell said, "…there’s some drawls that a lot of people have similar."

"It was just something…I guess his way of talking. It was something I couldn’t repeat."

Hartnell said there was a distinct Cadence to Z’s voice. Meaning he carried his words in a very distinct way or there was a recognizable rhythm to them. One could almost interpret (from other accounts of his voice) that Z was very articulate when speaking, and also thought not only about what he was saying, but how he was saying it.

Interesting possibility Foreigner, and good to see you here and posting

Officer Slaight said that Zodiac sounded in his early 20’s,and Bryan himself stated that his voice sounded like a ‘student’s’. I personally think there’s a good chance Zodiac was in his early 20’s,and perhaps Bryan did know him,or had ran into him thru Friends etc,and remembered his voice, perhaps Z was a fellow student of Bryan,who knows

One can make the argument that the following line in the Stine letter is actually a reference to the Lake Berryessa attack.

I am the same man who did in the people in the North Bay Area.

Napa is definitely North Bay. Vallejo is technically North Bay, but many people consider it East Bay. For example, in these interview notes, Bill Armstrong describes the initial Zodiac Killer attacks as "East Bay."

Cipher Killer in East Bay they were reading about…

I’m also struck by the verb used in the sentence, "did in." The Zodiac enjoyed making statements like "I am the killer" and "I am the murderer." Yet, here he uses the relative euphemism "did in." Certainly, "did in" can mean murder. But, it can also mean to "injure gravely." Therefore, the statement actually could be referring to both victims from the Lake Berryessa attack.

And, of course, it’s also possible that the statement is a reference to all three of the killer’s previous attacks.

Thanks for all of the replies. Foreigner – I found this very interesting so I did a Google search of voice cadence and found this site – http://www.armystudyguide.com/content/a … oice.shtml. It’s called Command Voice and it sounds like it’s mainly used by drill sergeants/commanders/instructors, etc. While Zodiac’s voice wasn’t described as being loud Bryan Hartnell stated that it had a "distinct cadence". Couple this with the information about Z possibly having a military background and perhaps this might tell a little more about him.

I do not think you can count Lake Berryessa as North Bay. Berryessa is north and east of Napa which is 15 miles from Vallejo or go through Fairfield or Vacaville which are in the central valley of California.

Napa is pushing the limits of being North Bay as it is a good 15 miles from San Pablo Bay, the northern end of SF Bay.

Just my opinion.
