Well IMO I don’t hear any immediate discrepancy between the two voices. I’ve spent quite a few years working in recording, mastering etc so I can offer that, at the very least for some credibility, in offering that opinion. Not absolute though, just my initial impression.

It wasn’t just though that people say. The call I believe was traced to the institution where Eric was staying and I think it was determined/suspected/suggested that Eric had also placed calls to Melvin belli’s residence so that backed up the trace evidence.

"It wasn’t just though that people say. The call I believe was traced to the institution where Eric was staying and I think it was determined/suspected/suggested that Eric had also placed calls to Melvin belli’s residence so that backed up the trace evidence."

According to what I have read, it’s actually the other way around. I read it last week online somewhere that Mel Belli had received several calls from someone claiming to be Zodiac at his home. He was not there to take most (if not any) of these calls personally. It was reported to LE that he was receiving such calls and as a result, the FBI set up a trace on Mel Belli’s phone. When the ‘Zodiac’ next called it was this call that they traced back to the institution where Weil was currently located.

As far as I am aware, the Jim Dunbar show never traced the calls. It was then assumed that because Weil was found to be the caller to Belli’s house, he was also the caller to the Jim Dunbar show. That is the way it happened according to the version I read last week.

Sounds about right. Sounds like the same thing I read. I just didn’t bother recalling the exact details but I thought it involved calls to Belli’s house as regards identifying Weil as the caller.

Could you find that source again to post it? I’m sure I could but since you’ve read it more recently you might have a better chance of finding it quicker.

Sure. The quote itself states:

"In his 1971 summary of the Zodiac case, reporter Paul Avery wrote that Eric Weil had been identified after calls to Belli’s home were traced to the mental hospital. In his 1975 book, GREAT CRIMES OF SAN FRANCISCO, San Francisco Chronicle reporter Duffy Jennings stated that police had been able to locate “Sam” after calls to Melvin Belli’s home were traced to the hospital in Oakland. Jennings wrote that police believed the imposter had been responsible for the calls to the television station as well as call to the Oakland police department in October. San Francisco investigators cleared Eric Weil as a Zodiac suspect."

An independent article, of whom Bob Dylan is the focus, makes mention of the fact that Eric Weil seen interviewing Dylan, was later said to have been responsible for making hoax calls claiming to be the San Francisco Serial Killer ‘Zodiac’ and the author of this article offers his/her opinion stating:

"The voice on the phone doesn’t sound like the same guy to me, but it’s hard to tell. A look through the master index of the San Francisco Chronicle at the library yielded no mention of Eric Weil."

Maybe I am making an ass umption out of myself here, but wasn’t it that the the police could only trace live incoming calls, but the phone company had a record of outgoing calls made? So if they knew that the call to Belli came from Sam, they could see that Sam had made a prior call to Dunbar.

I’d like to hope so and that didn’t make ass umptions out of themselves connecting Dunbar with no proof.

Hmm… gotta wonder if that was an assumption on their part given that the Oakland P.D. officer apparently felt that Weil was NOT the person who placed the call to Oakland P.D. that precipitated this whole episode. It would make a lot of sense if Weil was responsible for all of the Belli-related calls but then we would have Zodiac writing Belli copycatting the copycat. I wouldn’t put it past him to do just that but nothing in this case is ever simple, is it? This whole scenario would certainly have been handled very differently today.

First of all, you can say ‘ass umption’ three time’s in the next post if you like, it still won’t change the fact that it makes no sense at all. While splitting words like Christmas into Christ Mass does because they are two know words in the English language, sadly ‘Umption’ is not a word in usage now, nor do I believe it has ever been.
Secondly, it is not physically possible for one to make an assumption of yourself.

So, if we may just stick to the English language a moment and not resort to making up words that don’t exist while trying to make a point, then I will answer you by referring you to Mike Butterfields claims above that I have copied & pasted. If you think Butterfield is, as you seem to like to say, making an assumption out of himself *Shrugs shoulders – No idea how this is done* then you may want to ask Mike. Although I don’t think he will quite know what your talking about either.

Actually, Chappie, I’m just suggesting that it might be an assumption on the part of police that if Weil was traced to calling Belli’s home and the Dunbar show, he must have also made the initial call to Oakland P.D. as well. Of course, we’re getting that 3rd hand from Mike B.’s quotation from a reporter about what police believed. I’m honestly not sure what to believe but it just seems to conflict with the Oakland P.D. officer’s opinion that "Sam" was not the same person that called Oakland P.D.

Wasn’t there an article or report floating around that had more details about the Oakland Call in incident? I am sure I remember reading it.
