Zodiac’s favorite words
The killer’s first cipher was solved rather quickly by amateur codebreakers because they guessed that the killer would use words such as “I” and “kill”. Can similar guesswork help us solve the unsolved 340-character cipher? This is something people have been trying for years. But nobody has yet unlocked the mystery.
Zodiac sent many letters over the years, taunting the public about his crimes. From this collection of plain text, we can see what words he really likes to use in his writings.
Here are the results of an experiment that uses an algorithm to detect phrases and words that repeat in his writings. Perhaps somewhere among the results is something that might appear in the real solution of the 340-character cipher, if it indeed contains one.
