Previously I posted about The Mikado joke listing in the October 9. 1969 Stanford Chaparral.

I also posted about Mikado-Zodiac Killer correlations in the October 31, 1969 Stanford Daily, a series of items that would have to be noted as extremely amazing coincidences if they all were not intentional.

I would also like to include as a Mikado-Zodiac coincidence the October 24, 1969 Stanford Daily, with a student-written Message To The Zodiac Killer editorial on the same page with a letter to the editor authored by N okNok. This editorial ran the same day (10/24/69) as the Berkeley Tribe’s “A Message For The Zodiac Killer” written by Blaine, the primary accuser of Richard. Blaine said he wrote his editorial at the request of Richard.

“Knock Knock” jokes of course have been around long before Zodiac. But a search of several newspaper archives yields that the spelling “nok nok” is not found anywhere, and is likely some of the hip lingo the hippies and cool cats of the day used. “N okNok” not only begs the question, “who’s there?” but also anagrams to “KoKo ZZ” when the Ns are rotated 90 degrees.

All of this points to Zodiac being interested in The Mikado long before July 1970 when the “Little List” letter was sent.

I propose that Zodiac was planning a Mikado-themed murder for October 1969. But something happened, circumstances changed. This might be in direct relation to the Paul Stine murder, or not.

Zodiac hadn’t been able to get a Mikado feature article in the Oct 9 Chaparral, or in another publication. Did the small review in the October 31 Daily suit his purposes? Was the anagrammed “KoKo ZZ” on the same page as the Message To The Zodiac Killer editorial enough for him?

Did Zodiac perform a Mikado-style murder sometime between October 1969 and July 1970 and we just don’t know about it?

I present the idea as a distinct possibility.

But unlike Lake Berryessa, where he wore a black hood with a white astrological symbol on it to be a prank with the Dick Tracy comic running in papers the next day, in this Mikado-themed murder no one survived to report the “prank,” no one to see the Ko-Ko outfit, or the sword, or whatever.

So, I conjecture he wrote about it in the letter(s) of July 1970.
