Most of the letters postmarked San Francisco could also have been mailed from San Mateo County, and from parts of Santa Clara County.

A couple appeared to have been mailed directly at Rincon Annex on a weekend.

one other locational factor here ….. if Ray Davis in Oceanside was a Zodiac murder, then it becomes much more likely that Zodiac lived in San Francisco. Remember that the cab in Oceanside was taken to the neighborhood of the mayor’s home. The Stine killing took place a few blocks from the home of the mayor of San Francisco. How likely would it be that a Vallejo resident would know the location where the mayor of SF lived?

Yes, it appears a remarkable coincidence. Yet, there’s a cause and correlation problem here. Both murders occur in wealthy areas that are less busy at night, therefore affording the criminal in each case a better chance of escape. The fact that the mayor’s residencies are located in wealthy areas of town is no coincidence, however.

I’m not saying you’re wrong, but it could be equally be incidental. Furthermore, who is to say Zodiac isn’t copying the crimes of others? Perhaps, he is living vicariously.

There are a multitude of possibilities, but my impression is that he has some connection to Vallejo, rather than going from big city to small rural town to obfuscate impending investigation.

I could believe he was from Vallejo but living now in San Francisco. He could go back on weekends to see his folks, other family, friends. Or even if on his own he’d go back to a place he was familiar.

One of the interesting things about someone like Gaikowski is that he apparently lived in Vallejo at one point, 10min or so from crime scenes. So even if he isn’t from there, his familiarity with the locale and his recognition of its dark and lonely roads and hangouts reconcile with the idea of him going back there to kill. This of course applies to anyone from or living in the area.

As much a "remarkable coincidence" as the writer of the book that was found in Ray Davis’ cab being born a scant 50+ miles from Oceanside? Or having gone to school at Riverside Junior College, before it was known as RCC? Or having been a Merchant Marine during WW2? Or having worked at March AFB after the war as the chief surplus supply clerk, before embarking on his career as a novelist? Or having his main literary character’s first name happen to be a phonetic spelling of the first name of a subsequent, high profile Zodiac suspect? To paraphrase a certain headshrink…sometimes a coincidence is just a coincidence…some more "remarkable" than others.

Actually, you can’t pitch a brick 2 feet in this case without hitting another "remarkable coincidence" square between the eyes.

Were Vallejo residents hillbilly bumpkins that needed help tying their rope belts, let alone finding where the Mayor of San Francisco laid his head? Vallejo isn’t exactly Light Years away from SF, after all…so why would one consider it unlikely that a Vallejoan Z might easily deduce where the Mayor of a relatively close by metropolitan area might reside? He likely wouldn’t be residing on Skid Row, after all…

I barely know who the mayor of my city is. Much less where he lives. I might be able to find out, if I wanted to. But it would have been harder to find out then than it is now.

If Zodiac had written about the mayor of SF then this might amount to something, yet he didn’t. He didn’t mention him ever, not once.

"I barely know who the mayor of my city is. Much less where he lives. I might be able to find out, if I wanted to. But it would have been harder to find out then than it is now."

Mayor Alioto’s home address was spammed by the numerous counterculture newspapers. Why? Because back in 1969, Alioto, the mayor of San Francisco — under pressure from the ruling class — was responsible for encouraging the police to use any means necessary to get rid of the counterculture. Here’s what it looked like as published in one of those counterculture newspapers —

Alioto lived a block and a half from the Stine crime scene, and his house was under 24-hour police guard. That may be where Pelissetti and Peda were when the call came in.

Jesus, that’s an embarrassment coming from a presumed Dashiell Hammett fan, isn’t it, though?

Oh, well…whatever. I’ve always thought Ross MacDonald, Ed McBain, Mickey Spillane and Don Pendleton were the real measures of intelligence, common sense and grit in the hard-boiled detective/crime fiction arenas, anyway…and you, Nick, might’ve just proved me right.

Here’s a tip, Nick…crack a newspaper once in a while…it’ll serve you well, I assure you.

Even as a 5 year old way back when in the 1970’s I knew who the Mayor of NYC was and where Gracie Mansion was in Manhattan…yet I didn’t live there.

The absolutely mind-boggling disconnect with common sense in so many of the people who profess to know about the Zodiac case is astounding.

Yes, and it’s getting worse.

Yeah, but you have to explain why something is common sense, rather than merely asserting it. If the case could be solved by common sense, then it’d have been solved long ago.

Mayor Alioto’s home address was no secret.

Presidio Terrace. Interesting point about Pelissetti and Peda.
