Zodiackiller.com Message Board: Letters: I am CRACKPROOF

According to Graysmith on Oct6 1970 the Cronicle
recieved a file card with a cross drawn in blood. In this message the author used the term I am Crackproof. This apparently was assumed to be authentic at first but later "filed as another copycat effort".
Moving forward to March 15 1971 the Los Angeles Times gets the "Blue Meannies" letter in which the Author States "Like I have Always Said I am Crackproof.
It seems a unlikely Two different people would use the same phrase.
Is this the Graysmith Factor?
Do we have 2 authentic Zodiac Letters?
Do we have 2 Fakes?
Might this phrase be something to look for in the 340 Cipher? given Zodiac Always said???

Is it not possible that one copycat, if you subscribe to this particular belief, wrote both of the letters in question? It takes a peculiar sensibility to do this in the first place, and the copycat phenomenon is not, to my understanding, as prevalent as Hollywood would have us believe. By the way, a copycat would be most concerned with using the same phrases as the bona fide killer for legitimacy, while a copycat who wrote several letters would be concerned with internal consistency. To neglect either would be to defeat the purpose of copying in the first place. To my knowledge these are regarded as authentic Zodiac letters, but I may be wrong. The only fake Zodiac letter that I am aware of is the infamous 1978 missive. You have probably been "Graysmithed". I'm sure there were many other crank Zodiac letters- in fact, it would be hard to imagine it not happening- but I don't believe they would have been given much, if any publicity.
p.s. A lot of us are going to be "Graysmithed' when his sequel arrives in the bookstores later this year. We can only hope that he does a better, more thorough job this time around.
p.p.s. Penn in 2004. Ride the wave!

It naturally would appear that the police were in error in assuming the Oct6th letter to be the work of a copycat.However one would think the arrival of the second might have prompted them to revise their original assumptions.
Assuming the first to be authentic, would it not make it as important as the Stine shirt as far as blood evidence was concerned?.
It may have enabled the police to tie Zodiac to a definite victim.The fact that this possibility was not covered ( at least not that I have seen)
is why I raised the subject. As far as "like Ive Always said I am Crackproof" is concerned, well he obviously did'nt at least not in his messages
unless it is a phrase used in his 340 cipher.

I am curious as to opinions more members here as to whether the file card was authentic. Does anyone know what caused the card to be called into question? Was it examined by Morrill, or others?

Also, I notice that it does not appear reproduced anywhere that I can find it? Has anyone ever seen a reproduction of this card and if so, where?

I find some interesting aspects to it that relate very closely to other Z mailings that I personally find unlikely to be things that a copycat would pick up on and be apt to duplicate.

Thanks everyone.

Ray, I've got a facsimile of the card at http://home.att.net/~mignarda/FKcardx.gif. I believe you can see the original somewhere in the FBI files, but I'm not sure where.

This card, though without handprinting, sure seems to have that smartass, Zodiac 'tone', like in most of his handwritten letters.

I personally believe that the 10/5/70 FC or file card is a Zodiac.It is noted that "crackproof" is used in the FC and the same word is employed by Zodiac 3/13/71,"Like I have always said I am crackproof."We need not take Zodiacs "always said" literally in the sense that he wrote this expression in the past in several letters.In studying his letters we find that he utilizes perimeter concepts.For example,he wrote that he killed the couple on LHR during "Christmass"for the 20th of December.He says that he killed the cab driver over "by Washington st. and Maple st."
I think the the FC card "crackproof" statement was set in stone for Zodiac and it was a bellwether for declaring he was "crackproof" for all time.He may have meant to say 'Like I have said I am crackproof' and he got carried away and used the word "always."Crackproof is a neat tie in to the 10/5/70 FC.
A hole punch was used(like on the Pines card )and the FC as a FYI.For sure the holes on the FC were to represent victims which numbered 13.
This links to the Halloween card(which has 13 victims pictured as eyes) sent just a short time later 10/27/70.
Two missives in the SAME month was not unlike Zodiacs past send times.Two communications were sent in 11/8/9/69.April saw two on the 20/28 of '70.July we have two on the 24/26 followed by TWO in October of 5/27/70.
Both the 10/5/70/27 missives were BRUSH LETTERED (as was the Pines card).
Z,I believe, is referring to Bates;SB couple(we know they 'fought';Lass(?)and some other unknown victms when it says"Some of them Fought it was Horrible."We do know Bates/SB male(Z or not),as the Confession says,'fought.'
"The pace isn't any slower."It says in the first Z cipher "I will not give you my name as you will try to SLOW down or stop my collecting of slaves."
Another parallel is "What is the price tag now?"In the 4/20/70 missive he says"...how much money you have on my head now."
Both the 10/27/70 and the FC or file card were pasteups(as was the Pines and the 12/10/69 SAC "want Zodiac"Bee pasteup).
Other communications were in the 1 A postal zone (as the 10/5/70 card was)such as the three letters 4/31/69;6/26/70.
The FC starts with "Dear Editor" a Zodiac trademark.
These are just thoughts,but there is enough to at least suspect it was a Zodiac card.
I don't think a test of the glue used along with the ink on all three missives under discussion will solve the issue of common authorship because Z is known to change his various methods.If they are all the same it would be a confirmation.I don't know if the blue felt ink used in the Zodiac missives(except on the cardoor at LB)has been tested for common chemical properties or not!

I forgot to mention that the FC 10/5/70 (BDs B Day)stamp is identical to the one used on the "authentic"10/27/70 Halloween card and it is tilted in Zodiac fashion.The "S.F." is used which is an old Zodiac like designation for San Francisco.Of course he abbreviated the city in other ways too.
The section of pasteup that starts with "There are reports..."is upside down just like in the SAC Bee pasteup of 12/10/69.Inversion of statements is used in the occult for various reasons.The inverted bloody like cross is suggestive of the occult also.
I think Z gave some clues to link communications that would be in doubt, like using the same stamps on both Oct.'70 missives,etc.

Very sorry to post again- both sides(rare)of the file card can be seen on Jakes This is the Zodiac speaking,which, of course,is linked on this site.
