Yes it’s probably golf yet again. It has the theme of identity.

The Exorcist letter (January 29th, 1974) contains some strange symbols at the end.

Looks random and odd. Despite the usual spelling out of “To Kill” I have another explanation for them. In fact, To Kill might not even be mutually exclusive with my explanation, so I think it works as the Zodiac intended.

In golf, to identify the ball with the owner, they take a pen and draw a unique symbol on the ball. It can be a simple dot. A line. A signature. A scribble. All sorts of shapes. You can keep a note of other players symbols before you all begin.

Usually with a sharpie-type pen. ?

When people collect lost golf balls from the course, you can find an assortment of choice markings.

Some of them even thick and untidy.

How about a circle around that 8 for the Z13 cipher?

Even the top players have their symbols.

I would suggest that either the symbols are his own or he knows the symbols of professional golfers at the time and has arranged them in the Exorcist symbol.

Really nothing more or nothing less than that. A simple clue to golf again.

If the symbols can be matched to contemporary golfers at the time, it would be great. In the meantime I think this is consistent with my pines find.

Just keeping it all simple and parsimonious with the one theme. Golf. He stuck with the theme because it wasn’t discovered in his other communications especially the Pines card. If it works, it works.

I just hope officials assigned the case weren’t golf buddies and him their secret pal.
