The Zodiac Killer after killing four people in Benicia, Vallejo and Napa, suddenly switched the emphasis to the heart of San Francisco, mailing a letter to the San Francisco Chronicle on October 13th 1969, promising to target a school bus and 'pick of the kiddies as they come bouncing out.' Following this came multiple references to bombs, notably in his 'My Name is.. Cipher' detailing a bus bomb diagram and suggesting he was not responsible for wiping out 'that blue meannie with a bomb'. He was detailing the murder of San Francisco police officer Brian McDonnell on February 16th 1970, two months earlier, when a bomb exploded on an outside ledge of Park Police Station in the Upper Haight neighborhood. The Zodiac Killer then mailed the Dragon Card on April 28th 1970 stating 'I hope you enjoy yourselves when I have my blast', followed by the Button Letter cementing his connection to San Francisco by part referencing the murder of a man in a parked car, thought to be police officer Richard Radetich outside 643 Waller Street and sending an attached Phillips 66 Road Map, stating 'the map coupled with this code will tell you where the bomb is set'. Then on July 26th 1970 the Little List Letter was mailed, including two crosshairs, one with a prominent black circle including the acronym SFPD = 0 and the second referring us back to the Button Letter, stating 'The Mt Diablo code concerns radians + inches along the radians.' The emphasis appeared squarely over the region of his final murder, that of Paul Stine on October 11th 1969, so was the bomb the Zodiac Killer promised us, to be found somewhere in San Francisco, after all the Phillips 66 Road Map was entitled San Francisco and Vicinity.
The Zodiac Killer mentioned radians (an angle of measurement), of which one radian is valued at 57.296 degrees. If we look at the prominent black circle he gave us on the Little List Letter, its center falls over 246 degrees on a compass rose. (see right).
246 degrees is 4 radians + 17 degrees.
When the Phillips 66 Road Map was mailed on June 26th 1970 Magnetic North was approximated at just under 17 degrees.
4 radians = 4 X 57.296 = 229.184 + 17 degrees = 246 degrees.
So apparently the Zodiac Killer was very familiar with radians and the value of Magnetic North, unless we are assuming he was just lucky in his placement of the bold circle on the diagram. His further reference to SFPD next to this circle, makes one think this is where we should be centering our focus.
The final confirmed murder of the Zodiac Killer was that of Paul Stine at Presidio Heights on October 11th 1969 and in his letter mailed one month later on November 9th he again ridicules the police and lays out the details for his construction of a bomb.
Paul Stine had picked up his final paying fare that night from Pier 64 to the Air Terminal at San Francisco International Airport, before returning back to the theater district near the Mason and Geary intersection. This is where it is believed he picked up the Zodiac Killer for one last fateful journey.
We know the Zodiac Killer mentioned radians and inches along the radians, so let us start with complete radians. We know from above that the value of 4 radians is significant, so this being 229 degrees, we shall place a compass rose over Mount Diablo and see where this takes us, in respect of San Francisco.
246 degrees is 4 radians + 17 degrees.

It can be seen that 229 degrees falls on the south edge of San Francisco International Airport by Old Bayshore Highway.
Was the Zodiac Killer intending to ratchet up the fear by exploding bombs in the vicinity of the airport. Of course this hypothesis is just pure speculation, or is it. Let us take a further look at the Button Letter mailed on June 26th 1970, where the Zodiac Killer stated 'The Map coupled with this code will tell you where the bomb is set. You have until next Fall to dig it up,' and enter something alongside the code.

San Francisco International Airport is exactly 32 letters long and fits squarely alongside the 32 symbol Button Letter code. However the 246 degree mark falls somewhere between the Mason and Geary intersection and San Francisco International Airport, an area all too familiar with the Zodiac Killer. Was the bomb to be set according to the code above, but coupled with the map set at Magnetic North of 17 degrees, was to give us a directional location of 17 degrees due west of San Francisco International Airport, to arrive at a final value of 246 degrees he so precisely gave us in the Little List Letter on July 26th 1970.
