Also closely associated to the Radian Theory, is the thought that the Zodiac was may'be influenced by Pi, hence his choice of the word Zodiac as his moniker, and the crossed circle emblazoned on many of his postcards and letters.
Incidentally Pi is the ratio of a circles circumference to its diameter and valued at 3.14159265... or shortened to 3.14 for simplicity.
As described on many internet articles 3.1 4 15 9 26 can be displayed alphabetically as CADOIZ, which is an anagram of ZODIAC, but is there anything else, anywhere in the killers correspondence, to suggest other links to Pi as a possible factor which influenced the actions of Northern California's most elusive murderer.
The Zodiac seemed to grow attached to his crossed circle, this became apparent in the Halloween Card when he crossed the words PARADICE and SLAVES forming four quadrants, where he placed the words BY FIRE, BY GUN, BY KNIFE and BY ROPE.
The Halloween Card, of course, is a great source of ideas when theorizing about the Zodiac's intentions, as it has a multitude of variables, but without doubt he meant something to be understood from the card, it just depends on which theory you believe carries the most weight.
Well first, we shall examine the skeletons hand on the front of the card, it has three fingers raised and 14 written on the palm, therefore giving us 314, the first three numbers of pi.
Once the card is opened we see the text 4-TEEN. The Zodiac could have written 14 once more but chose to highlight a separation, why, well a teen is someone who reaches the age of 13. Now inserting this instead of the word TEEN we get 4-13, which is 314 in reverse, remembering the Zodiac often flipped his text apparent in the two postcards he supposedly authored either side of this one, in the 13 Hole Postcard and Pines Card.
Now take a look at the word BOO, could it conceivably be possible that the B is a 1 and 3 in close proximity, to form 314 in reverse with the four eyes underneath.
Then we have the strange symbol placed on the Halloween Card envelope and at the foot of the card once opened. This could be interpreted as ZVF, Zodiac Victims Fourteen or a host of other things. But lets take it as a numerical value. Firstly, the 4 dots as simply the number 4, then the rest as a joined 7 and F. With F being the 6th letter of the alphabet and the fact it is joined to the 7, we shall proceed with its sum total of 13, to form 413. We now have 314 in reverse yet again.
It dosen't stop there as we shall see. Many observers have speculated why the Zodiac chose to reverse the letter N, when he wrote BY KNIFE on the back of the Halloween Card. Well N is the 14th letter of the alphabet and immediately right of it, is the letter C, contained in the word DICE, and C is represented by 3 numerically to form 143, but of course the N is reversed, so we have to flip 14 to get 41, thereby creating 413 and pi in reverse once more. And the letter P is further to the right, part of the text BY ROPE, is it stretching a bit too far to believe this stands for pi.
The 4 quadrants of death, separated by the 13 letters of PARADICE and SLAVES could have been pointing us to the fact that Pi was the Zodiac symbol all along, but then again it could mean absolutely nothing.
Bearing in mind previous articles, the only high profile suspect with a birth date of 3.14 is Richard Gaikowski, who was born on 14th March 1936 and the Mikado, which featured in Zodiac's Little List Letter and the Exorcist Letter, first opened its doors to the paying public on March 14th 1885, and the inspiration for a cunning killer ?. Absolutely not, what you have just read is number play and a fair sprinkling of imagination. Nothing more
