In this newspaper collection compiled by cryptographer Dave Oranchak it can be seen that a flurry of newspaper articles preceded this 'Zodiac' mailing, from July 11th 1978 to July 18th 1978. They were entitled The Rise and Fall of a Good Cop, New Puzzles Further Muddle Zodiac Case, Officials Jittery Over Latest Zodiac Puzzle, New Zodiac Disclosures, Feinstein Says Toschi's Being Crucified and Gain Talks About Toschi. They all highlighted the plight of Inspector David Toschi of Homicide Detail, who came under suspicion for forging both the Exorcist letter, mailed on January 29th 1974, and the most recent 'Zodiac' communication on April 24th 1978, which stated "Dear Editor, This is the Zodiac speaking I am back with you. Tell herb caen I am here, I have always been here. That city pig toschi is good - but I am smarter and better he will get tired then leave me alone. I am waiting for a good movie about me. who will play me. I am now in control of all things". Considering this July 19th 1978 letter was mailed just after these newspaper articles about David Toschi, parroting "I am in control of all things", it is a fairly safe bet that this typed communication was addressing David Toschi personally.
Quicktrader, from the Zodiac Killer Site forum, highlighted the first clue in the letter, in which the author states "I have my real name on a small metallic tape", "I have my name on the bottom of the lid with the scotch tape" and "my tape is waiting for me all over California". Scotch Tape could be bought all over California, and this version of the product did have a name on the bottom of the lid. Was this the Zodiac Killer insinuating that his forename was Paul?
The author of this letter likely knew that David Toschi had been demoted from homicide detail to pawn shop detail and was currently taking a short holiday. What better way, in true Zodiac style, to take the mickey out of the demoted inspector by offering the steward of the pawn shop detail a game of chess. The answer is always so black or white.
