The Zodiac Killer mailed two letters on October 28th 1987 to the Vallejo Times-Herald and San Francisco Chronicle, so it had been nearly three years since any confirmed correspondence had arrived at any newspaper offices, when on September 25th 1990, somebody insinuating he was the Zodiac Killer mailed the Celebrity Cypher postcard to the Vallejo Times-Herald containing a 63 or 64 character cryptogram. This correspondence was reminiscent of the April 20th 1970 code mailed by the Zodiac Killer, as it too promised a name at the foot of the postcard and the address side of the communication. Both the April 20th 1970 letter and September 25th 1990 postcard tempted us with a 13 character name. The final three words on the September 25th 1990 message were highly suggestive of the words "My name is". We know that the Zodiac Killer was often triggered into writing to the newspapers because of recent published articles that featured him, but at this point in time (after nearly 3 years), the newspaper articles about the Zodiac Killer had become extremely threadbare. Therefore, the pool of newspaper articles that triggered the September 25th 1990 postcard shouldn't be too difficult to find. This cryptographic postcard message was also highly relevant to the 340 cipher mailed on November 8th 1969.
The newspaper article began with "A former Vallejo woman related to one of the Zodiac's victims told a national television audience Wednesday that she is being harassed with death threats from the serial killer. Pam Huckaby, a guest on Sally Jessy Raphael's talk show, said that just days before she was to leave for New York to film Wednesday's show, she was assaulted and knocked unconscious in her home near Antioch". The newspaper continued "The killer is called the Zodiac because of his cryptic messages, loaded with astrological symbols, to the news media and investigators". But here is the crucial part of this newspaper article, where it stated "In a 1986 Times-Herald interview, Huckaby said she received annual calls from somebody claiming to be the Zodiac who said "This is the Zodiac speaking. I have collected the slaves I needed to collect. Now I'm going after the family". The Zodiac Killer in his 340 cipher stated "I am not afraid of the gas chamber because it will send me to paradice all the sooner. I now have enough slaves to work for me where everyone else has nothing when they reach paradice". In summary, we have two cryptographic communications, very likely a response to celebrities appearing on a TV show, both occurring just weeks after the show aired.
Below are two possible decodings of the Celebrity Cypher postcard, bearing in mind Pam Huckaby was the focus of the Sally Jessy Raphael Show and subsequent Vallejo Times-Herald newspaper article.
A few months after the Celebrity Cypher was received by the Vallejo Times-Herald, beginning in 1991, another series of cryptograms would be mailed concerning another TV show host. John Edward Walsh Jr. is an American television personality, and victim rights advocate, and the host/creator of America's Most Wanted. Beginning in 1991, John Walsh started receiving a sequence of sinister letters and cryptograms that many have considered may have been authored by the infamous Zodiac Killer. The title of the fifth cipher, accompanied by a 180 character cryptogram, read "Hi!, Remember me?", while another was signed by the pseudonym of "Scorpion". The author of these latest series of letters is unknown, but we have three high profile TV hosts, connected closely to several cryptograms, with the most recent offerings mailed in 1990 and 1991, just months apart.
