I'll DO IT TO BECAUSE I DONE IT 21 TIMES. I CAN'T STOP BECAUSE EACH ThAT I KILL MAKES IT WORSE AND I MUST KILL MORE. MAN IS ThE MOST PRIZED GAME. ILL NERVER GIVE MY NAME BECAUSE YOU dONT UNDERSTAND. NEXT TIME I WILL SEND A PATCH OF HUMAN SKIN if their is SOME Left OVER.
"Tis the Zodiac Speacking. Why can't you stop me. I can't stop killing. Stop listening t(o) phonys. If this is not on your front page in a week I will skin 3 little kids and make a suit from the skin".
The wording in the letter "I'll do it to because I done it 21 times" is consistent with a mailing date sometime after the March 13th 1971 Los Angeles correspondence from Zodiac, claiming 17+ victims. This letter and cipher appears at first glance a dubious Zodiac communication, but as Zodiologists.com point out, how difficult would it be for a hoaxer to mimic the ciphers or crosshairs of Zodiac. The fact the author failed to do this, should be pause for thought. There is also something about this letter that indicates its author had created another 'Zodiac' communication. The other communication, also mailed to the San Francisco Chronicle on July 13th 1971, mirrored the 148 character cipher and letter in one crucial way - the victim total. The last two widely accepted Zodiac communications were the March 13th 1971 Los Angeles letter claiming 17+ victims, and the January 29th 1974 Exorcist letter claiming 37 victims. The author of the above correspondence had 19 victim totals to choose from (18 to 36), yet he chose the total of 21, exactly the same as the total mentioned in the July 13th 1971 Monticello card, which featured in the San Francisco Police Department DNA report under "suspected Zodiac correspondence". Neither the 148 character cipher and letter, and Monticello card were released to the newspapers in 1971, so it's unlikely that the author of the above correspondence just get lucky by randomly choosing 21 victims and thereby mirroring the Monticello card.
The Monticello card was mailed on July 13th 1971 stating:
"Near Monticello Shought Victims 21 ...... In The Woods Dies April".
By my rudimentary calculations, the 148 character cipher and letter should have been mailed on May 3rd 1971, about ten weeks before the Monticello card. If somebody can find the exact date of mailing regarding the 148 cipher and letter, it would be of immense value. The Monticello card was not published in the newspapers, therefore the notion of a victim total of 21 having been chosen by two independent authors looks extremely unlikely. If the Monticello card was designated as "suspected Zodiac correspondence" by the San Francisco Police Department, then by extension, the above correspondence should be afforded the same value.
