The Zodiac Killer’s infamous Z340 cipher, long considered one of the most cryptic puzzles in criminal history, contains a web of symbols and patterns that, when carefully studied, reveal potentially ominous messages. One such clue can be found in the 12th row, sixth column—where the repeating letters “KK” appear. This has been interpreted by investigators as a subtle nod to the Ku Klux Klan (KKK), possibly hinting at extremist ideology or racial motivations underlying the cipher’s broader narrative.
The cipher begins with the word “Her”, followed closely by a (hidden) large crosshair symbol—Zodiac’s infamous signature. Tracing from this point, the cipher reveals the scattered appearance of the words: “NY”, “body”, “Otom”, and “bomb”. Taken together, this sequence has been interpreted as:
“Her New York Body Atom Bomb”—possibly referencing both a literal and symbolic explosion, one that could target both the Statue of Liberty and the ideals she represents.
This theory gains further strength when seen in the context of historical events. Around the same time Z340 was circulated (early 1970s), the Transamerica Pyramid was under construction in San Francisco—a structure with a pointed, needle-like form. Meanwhile, the USS Liberty incident, in which Israeli Defense Forces attacked an American naval ship during the Six-Day War, had already occurred a few years earlier in 1967, stirring suspicions and conspiracy theories. These events, coupled with the cipher’s nuclear language, raise the chilling possibility that the “atom bomb” clue could symbolically point to the Transamerica Pyramid itself as a future target or warning.
Another intriguing section of Z340 lies directly below the word “Her”, where the characters N, P, +, a horizontal H, and BY appear. Through a symbolic decoding:
- Rotating the “N” and horizontal “H” clockwise reveals the letters Z and H.
- Replacing “P” and “H” with their previous alphabetical letters—O and G—yields the string:
Z, O, G, Her. - When combined with the word “BY”, the message becomes:
“By Herzog.”
This phrase, “By Herzog”, led the investigator to a chilling interpretation:
“A civil war would erupt following an atomic bomb explosion by Herzog.”
Adding to this intrigue is Mike Herzog, who was appointed as U.S. envoy to Israel on August 6, 2021—the anniversary of the Hiroshima bombing, a historical marker of nuclear devastation. On November 15, 2021, the day he arrived in Washington, D.C., Russia tested an anti-satellite missile, while a devastating explosion occurred at the Liverpool Women’s Hospital in Kensington, linked in symbolism to “Her Majesty”—connecting to the cipher’s word “Her.”
Later, on March 8, 2022, the anniversary of the MH370 disappearance, Mike Herzog tweeted about donating six electricity generators to Ukraine. This gesture drew connections to a Zodiac diagram depicting an electrical circuit, interpreted by the Clive & Lally Investigative Agency as containing symbolic links to the Transamerica Pyramid and Seattle’s Space Needle.
Moreover, the Delta Airlines sandwich needle incident was one of three significant events investigators connected to the signature of the Treadstone Zurich account belonging to Jason Bourne, a character inspired by deep-state black operations. The other incident was the MH17 aircraft shootdown over Ukraine and connections to MH370, implying a sinister thread of staged global events tied back to cryptic clues within Zodiac’s work.
This leads to the chilling conclusion that Mike Herzog’s tweet, seemingly innocent, may symbolically tie into the Zodiac’s cipher through interconnected signs, dates, and references. Supporting this theory is the release of Mission: Impossible – Ghost Protocol on December 21, 2011, exactly one year before the Mayan doomsday prediction. The film’s plot—which involves the detonation of a nuclear device to trigger global chaos—may have been inspired in part by Zodiac’s Z340 cipher and accompanying diagrams.
