After convincingly demonstrating that the 1974 Zodiac letters were forged by members of the SLA, Richard Grinell of ZodiacCiphers.com has brought our attention to a 1990 postcard which from all appearances looks like the work of the Zodiac. My suspect George Karadanis would have been approaching his 60th birthday in 1990.
Here we have Karadanis’ name . I throw in the P because I’ll bet sometimes he calls himself Joey Paradise – a mob name for those who couldn’t pronounce Karadanis. The + sign has been given 2 solutions, K and P. It comes in handy later. Of course it only works if you know The Names in advance.
Above: I’m making the assumption that the address is a California one- the B symbol is a C letter.
Filling in more letters in the address. Now using more K/P’s for +
The short message being filled in.
The complete sender’s address after choosing between our K’s and P’s:
Royal Oaks / Crown Road / Petaluma, Ca
The intersection of these two streets in Petaluma is currently the site of a senior living community. I’m going to research its history. Note Petaluma is just a few miles north of Vallejo, where the card was received.
