“…they may be dealing with one or more ersatz Zodiacs–other psychotics eager to get into the act, or perhaps even other murderers eager to lay their crimes at the real Zodiac’s doorstep.“ L.A. Times, 1969
A good article about him: http://www.asqde.org/about/ASO_award/ar … rticle.pdf
This goes back to 1965, co-written by Shimoda. Very technical about Ball Point Inks: http://scholarlycommons.law.northwester … ntext=jclc

You’re welcome.
I found it quite informative as well. Although I doubt he was on the Zodiac case in 1966.
