The pasted clues on the reverse side of the postcard included "sought victim 12", "Sierra Club", "Peek through the pines", "pass Lake Tahoe areas" and "around in the snow". But did the Zodiac Killer give us any extra clues on the front of the postcard that pointed toward the missing nurse? If the punch-hole on the reverse side of the card was depicting the burial or deposition site of Donna Ann Lass, could there be a clue to this on the front side of the card by the punch-hole, that somehow indicated her name?
The punch-hole on the front face of the postcard was positioned where you would normally place a name and return address, but the Bay Area murderer just wrote "Zodiac", with the letter "d" being touched by the north prong of the crosshairs. On the right side was the Abraham Lincoln 4c stamp. The initials of Abraham Lincoln are "AL". So reading from left to right we have "DAL", which are the initials of Donna Ann Lass. At the bottom of the postcard the Zodiac Killer wrote "attn. Paul averly = chronicLe". The two things that stood out were the use of the letter "L" in Paul Avery and the capitalized "L" in Chronicle. Therefore, from top down we have the "DL" of Donna Lass. Although this is probably another case of seeing patterns where they don't exist, I wanted to discover if there was any connection to the punch-hole (burial site) and the name of Donna Ann Lass. There is a way to get "DLF" (Donna Lass Fourteen) from the Halloween card envelope but I'm not going there, because that would almost certainly be seen as stretching the fabric of reality.
