However, there are crucial parts of the Daniel Williams story that were not covered in the San Francisco Chronicle article above. The day after this article was published, the Bus Bomb letter was postmarked, meaning it was out of the Zodiac Killer's hands by November 9th 1969. The Bus Bomb letter continued the theme of threatening schoolchildren by means of a bomb. But the November 9th 1969 letter contained one important line, after his introduction of "changing his way of collecting slaves". He stated "The police shall never catch me, because I have been too clever for them".
The sadistic phone calls to Daniel Williams began on October 23rd 1969 and lasted 10 days until November 2nd 1969, with the caller mocking police by stating “I’m too smart for them". The Zodiac Killer in reference to the police on November 9th 1969 (Bus Bomb letter), stated "The police shall never catch me, because I have been too clever for them". Very similar phraseology aimed towards the police by the real Zodiac Killer and somebody claiming to be the Zodiac Killer, separated by approximately one week. The expanded story of Daniel Williams (in the Desert Sun on November 10th) was copied from an identical version in the San Mateo Times newspaper, published on November 8th 1969, which covered the details of the phone call boasting “I’m too smart for them". But if the Zodiac Killer only read the Chronicle article (which didn't cover the phrase), then it's rather fortuitous that he would also use the near identical wording of "I have been too clever for them" at the beginning of the Bus Bomb letter on November 9th 1969. If they were not the same person, then there is a possibility that the Zodiac Killer read the version of Daniel Williams story, covered in the San Mateo Times or another newspaper prior to the mailing of the Bus Bomb letter, and used the phraseology of the sadistic caller detailed in the newspapers in his latest letter, so as to convince the police he was the caller and poisoner of Daniel Williams. Does the phraseology suggest one perpetrator as sadistic caller and Bus Bomb letter author, a Zodiac Killer mimicking the newspaper articles, or is the wording just a simple coincidence?
