It seems that almost everyone agrees that Zodiac's 'Death Machine' is, as it appears in his letters at face value, a bomb. But for me, always cynical and cautious of Zodiac's words and meaning, I have long thought that the Death Machine isn't what he seems to suggest is it, at least at face value.
I'll not beat about the proverbial bush and simply say what I believe the 'Death Machine' is. My personal opinion is that the Death Machine is....Zodiac. It's not a device, object or weapon as such, but rather, Zodiac himself is the Death Machine. Again, this is just my opinion, an alternate to the widely accepted belief. It seems that either the writer is speaking in the third person, or, he actually really is not the Zodiac killer himself, but simply the Zodiac letter Writer.
Here first, is what Zodiac wrote, then below, I'll try and show what I think it possibly means.
"The death machine is all ready made. I would have sent you pictures but you would be nasty enough to trace them back to developer + then to me, so I shall describe my masterpiece to you. The nice part of it is all the parts can be bought on the open market with no questions asked. 1 bat. Pow clock -- will run for aprox 1 year. 1 photoelectric switch... "
Z then list what appear to be parts or devices that can be bought to make a working bomb. He continues:
"the system checks out from one end to the other in my tests. What you do not know is whether the death machine is at the sight or whether it is being stored in my basement for future use. I think you do not have the manpower to stop this one by continually searching the road sides looking for this thing. + it wont do to re-roat + re schedule the busses because the bomb can be adapted to new conditions."
Ok, so here's why I think Zodiac is hiding clues right in front of us. (Keep in mind the following comments are made directly after he's explained that cops pulled a goof and failed to catch him on Jackson St)
He starts off: "The death Machine is already made." Zodiac himself has come to life, so to speak.
"I would have sent you pictures but you would be nasty enough to trace them back to developer + then to me, so I shall describe my masterpiece to you" Here I believe he's talking about photo's of his residence, or where he at least hid when they searched for him in and around the Presidio, and the 'developer' he speaks of is, IMO, a land and property developer.
" The nice part of it is all the parts can be bought on the open market with no questions asked. 1 bat. Pow clock -- will run for aprox 1 year" Zodiac, the death machine, will be active and his series of kills will run for approx. 1 year. His actual active attacking period ran from Dec, 68 - Oct, 69. Zodiac is the ticking time bomb, and he will be active for one year.
"the system checks out from one end to the other in my tests. What you do not know is whether the death machine is at the sight or whether it is being stored in my basement for future use. I think you do not have the manpower to stop this one by continually searching the road sides looking for this thing. + it wont do to re roat + re schedule the busses because the bomb can be adapted to new conditions."
Remember, this letter's first part is all about how he managed to walk away from police who were within a stone throws distance of him minutes after he committed his latest murder. So IMO, these 4 sentences here are cryptic hints at how he killed Paul and then avoided capture. So....
"The system checks out from one end to the other in my tests." His dummy runs via taxi he's been making from Geary in The Theatre District, to Washington & Cherry and, in his tests, the system works fine.
"What you do not know is whether the death machine is at the sight or whether it is being stored in my basement for future use." What we don't know is whether the Death Machine, aka Zodiac, is at the sight (Julius Kahn and The Presidio) or whether it, or he, is being stored, or hiding, in my basement for future use. I think Zodiac may very well have been in a home on Jackson, hiding in the basement of either his own home, or a friends. His 'Masterpiece' mentioned earlier is his home, or that of a friend, and he can't send photo's of it to police to show them exactly where he was when they were searching Julius Kahn because they would get a developer, a land and/or property developer, to locate where that property was exactly.
His next comment is referring to the police efforts in the Presidio and along West Pacific Avenue: " I think you do not have the manpower to stop this one by continually searching the road sides looking for this thing."
He is saying here that they will need more than numbers and manpower to catch him, and continually searching the road side's (along West Pacific Avenue) looking for him won't help to capture him either because he isn't there.
"it wont do to re roat + re schedule the busses because the bomb can be adapted to new conditions." He's saying the bomb, AKA Himself - The Zodiac - can be adapted to new conditions which, I think, is his way of hinting he's leaving the area soon.
He ends the letter with a warning: "Have fun!! By the way it could be rather messy if you try to bluff me." This last comment here is one that doesn't really make sense to me no matter whatever the context. Nobody has tried to bluff him, so why should he make this comment? It could be in reference to Fouke never mentioning that he'd seen Z walk up the steps and toward the residence of 3712 Jackson, and Z knows this and thinks they are keeping that quiet pretending they don't know that's the house he went toward, instead searching Julius Kahn and the surrounding area. If he has just told them cryptically that the death machine, himself, ran into his masterpiece that night, his home for which he cannot send photo's of because that will give away where he was, and was hiding in the basement then maybe he, like me, can't understand why the cops never dashed to the back garden of 3712, nor knocked the door, after two cops had seen him going toward the house? Like me, he may not have been able to understand how and why they never dashed straight there instead of Julius Kahn because that would be standard police practice to speed straight to the place where the suspect was last seen. Maybe he thought that they were bluffing him by only pretending not to be interested in the grounds of 3712, and that this is a bluff designed to catch Z off guard, and in his mind they may be planning a surprise visit without knocking before they come through the font door! Maybe this is what he means by "It could get messy if you do that."
To finish, I remind readers that this is only a theory, I am not claiming it is for certain what Zodiac's letter meant to convey, merely speculating.
As I started by saying, this is just one personal theory I have as to the meaning, or interpretation of the letter when it's not taken for what Zodiac knows it will be taken for, at face value.
I've also long believed that his threat to 'wipe out a school bus someday, just shoot out the tires and pick off the kiddies' is a specific threat to a specific school child, but masked as a general threat. The school bus is symbolic and simply means his target is of school age, and the 'kiddies is actually the eight year old child that saw him and gave police a name. Anything to back that up? Yep, Z's own words in the next letter, the one after he has threatened to wipe out the school bus, where he now almost dismissively states "If you cops think I'm going to take on a bus the way I stated I was, you deserve to have holes in your heads." In other words, if they ever thought that was really what he meant by the threat, then they are idiots.
