THE LOCATION OF THE BOMB [PT3]

9/24/2019

 
In the final instalment of this series we will attempt to refine the previous conclusions gleaned from the Zodiac Killer letters.
The Zodiac Killer stated on April 20th 1970 "I hope you do not think that I was the one who wiped out that blue meannie with a bomb at the cop station. Even though I talked about killing school children with one. It just wouldn't doo to move in on someone else's teritory.  But there is more glory in killing a cop than a cid because a cop can shoot back.  I have killed ten people to date. It would have been a lot more except that my bus bomb was a dud.  I was swamped out by the rain we had a while back." In the correspondence, the Zodiac Killer was referring to the murder of San Francisco police officer Brian McDonnell on February 16th 1970, who suffered devastating and sadly fatal injuries two months earlier, when a bomb packed with fence staples exploded on an outside ledge of Park Police Station in the Upper Haight neighborhood. The wording in the letter suggested that the Upper Haight neighborhood was not somewhere he was prepared to venture, but the suggestion of a school bus bomb and police station, when we take into account the SFPD positioned strategically by the bold, black circle on the Little List crosshairs and indicative of a location point, brings forth the notion of a school bus bomb under the noses of the San Francisco Police Department. Targeting a school bus within sight of a police station would certainly have dealt law enforcement a mighty blow.
Picture
The Zodiac Killer may have had a location in mind, despite the fact it was never followed through on - and this location has tentatively been identified as four radians (+magnetic north) and five inches along the radian in two previous articles. The exact position he had in mind to set up his photoelectric cells to detonate the bomb didn't necessarily have to conform to these measurements exactly, just be close enough to be rounded off by the Zodiac Killer. However, the other clues he gave us in the April 20th 1970 and July 26th 1970 communications were replete with information. We narrowed down a section on Google Maps between Daly City and Ingleside in San Francisco (between 246 and 249 degrees).

To narrow down the location even futher, we should be looking for a bus route approaching a school from north to south (so the sun is rising from the east on the left side). The roadway must have sufficient embankment on its right side to elevate photoelectic switch B. It must be within the parameters of 4 radians and 5 inches (allowing for a small margin of error). The addition of the pronounced black circle within the crosshairs of the Little List Letter in the form of SFPD=0, is suggestive of a location close to a San Francisco Police Department. In other words, the Zodiac Killer may have intended his "blast" right under the noses of law enforcement: "Hey pig doesnt it rile you up to have your noze rubed in your booboos?" Despite not knowing the exact topography of this location in 1970, I have found a site just 230 feet from Ingleside Police Station alongside Southern Freeway.

Fantastic one, Richard! That would have to be the ultimate location in line with the bus bomb diagram. And would definitely sting even more than having a bomb planted at the station itself.

And if that location didn't go unnoticed by Ingleside, he probably had achieved what he was looking for even without planting a bomb -- after all, they would have to anticipate that he would carry out his threat, even if it wasn't with the exact same design with a mirror. Especially on the heels of the Park Police Station Bombing.

And if he decided to set up a mirror -- no bomb, just mirror -- I imagine the sunlight bouncing off of it would get their attention.

I don't know whether my ideas carry any weight and were the ideas of Zodiac, but embarassing and ridiculing the police was prevalent in these bomb communications, and an explosion, or a threat of one on their doorstep would certainly get their attention. I don't know if the College of San Francisco car park was in the same location in 1970, but if it was, it would provide the perfect spot to reverse your vehicle right up to the embankment edge and perform your dastardly deed at night.

JD, when the Zodiac stated in this cipher is my identity, I wonder if he applied it literally in picture form in the 340, if you know where I'm coming from.

JD

I was thinking the same thing about the parking lot. Even if back then it was a grassy area with trees, unless it was extremely rough beyond the point of access, which I can't see for such a campus, I don't think that would stop someone from driving along there to the embankment.

I know where you're coming from on the 340 as well. Wouldn't that fit nicely. I may not have time this week / weekend, but will definitely keep looking for the FK angle. Nothing matching up, yet. But not very far along, either.

Richard

Got the message and understood. Good work. I won't elaborate so as to keep things under wraps JD. I've had no luck yet with FK either.

There was a Frank Kinder at 1744 Alabama Street, 850 metres from the payphone. Now that is a surprise - sorry for the pun.

Since you went ahead and posted Mr. Kinder, I will add here, quite interestingly, employed with MINS as well.

JD

It that isn't a double whammy.

Richard
9/25/2019 11:50:52 pm

By all means. There is always a way to do it without out and out accusing someone of being Zodiac. The guy I highlighted is extremely unlikely to be Zodiac, just that his initials matches a person I believe is a possibility. Just add a caveat JD.

JD
9/26/2019 09:20:35 am

Very good, Richard. Something for me to keep in mind, though I'm not sure I can quite get the hang of it. I always feel like I'm accusing someone, or feel like I've done that after the fact, even when I had no such intention.

Richard

Thanks JD for the update. No, I don't know when she started work there, sorry.

Z32 says Solar enkman (thats a solar panel) and Emperor of Japan, this is Telugu. Z340 is tamil, z408 is afrikaans, Z13 is Hindi. What you do to solve every one, capture a file that will allow special char to be copied, and drag and drop into translator let it detect language press enter. Zodiac couldnt cipher and he lied to you all. Z13 says glasses male me.

Please be aware that the Zodiac is all about solar. He was an installer and then owned his own company later in life. He eats breathes and thinks solar. Solar is also the secret word to open the misspellings and see another clue. Just type solar at the back of the misspelling. You will be displayed the second bigger clue.
