The Question Remains: Who is the Zodiac?
Only one killer solves the riddle of the Zodiac. Theodore Kaczynski, dubbed the Unabomber, fills in the gaps of the Zodiac mystery to present the full picture of both criminal careers.
—had experience building bombs which he threatened to use on school children as the Zodiac, and that he subsequently used to kill his victims as the Unabomber
—had a psychotic break at age 24, where he convinced himself that he was free of any moral or ethical standard that would prevent him from killing anyone he chose
—was a professor at UC Berkeley as the Zodiac murders began, and had easy access to all of the murder sites and victims
—was a prolific letter writer whose primary mode of communication was the written word, just like the Zodiac killer
—was a genius-level mathematician who was fully capable of creating the Zodiac ciphers, as demonstrated by the codes found in his cabin after his capture in 1996
—as the Zodiac, acted out his plan for gaining the attention of the public that he later presented in his Unabomber manifesto
—Possessed the type of weapons, disguises, and margin notes that would be expected of the Zodiac serial killer
The evidence is there. The answer is Ted Kaczynski.
