ZKS The Draftboard Letter
Morf13 has obtained several archived letters, from the FBI and law enforcement down the years and this becomes the latest addition.
Entitled 'The Draftboard Letter', and mailed in the March of 1968, approximately ten months prior to the first confirmed murders of the Zodiac Killer at Lake Herman Road.
The letter is a rambling mixture of drawings and text, giving the impression the author is under the influence of drugs, in fact he claims this in the correspondence, stating 'PS I don't write so good on acid'. But was it the Zodiac Killer. You decide.

ZKS  Found it!! By Fire, By Gun, By Knife, By Rope
On December 30th 2013 Tahoe27 found an interesting connection between the Halloween card and issue number 30 of the Tim Holt western comic strip.
It centered on one publication of Tim Holt, entitled 'The Death Wheel', that contained all four phrases of the Zodiac Killer's now infamous Halloween card, By Knife, By Gun, By Fire and By Rope, mailed to the San Francisco Chronicle on October 27th 1970 - and as fate would have it, the strange symbol depicted on the Halloween card appeared strikingly similar to the cattle branding logo found on Fred Harman's Pagosa Springs Ranch in Colorado. Fred Harman and Steve Slesinger were responsible for the Red Ryder western comic strip that ran from 1938 to 1965.
