I found this interesting. Has anyone else watched the Charlie Chan at Treasure Island movie? Basically, it’s a 1930s movie with a character called Dr Zodiac who uses deception to blackmail and kill. There are a lot of parallels between the movie and the Zodiac killer of the 1960s. He may have been inspired by it. Here’s the full movie if you haven’t watched it:
One interesting thing that I noticed was that at 48:05 the name "Kahne" was clear. It looks like "Kane" but not only that but "Kahne" is actually derived from "Kane" (https://www.ancestry.com/name-origin?surname=kahn and https://en.m.wiktionary.org/wiki/Kahn). And if you you look at the meaning of the words, they mean "boat" in German. What’s more is the Zodiac killer killed his victims near bodies of water.
Batman, there definitely is. If Lawrence Kane is the Zodiac, I imagine he must have watched the Charlie Chan movie and used that scene in a way to leave hints. One way that portion of the movie can be interpreted is that Charlie Chan is reading a book about Kahne’s (Kane’s) history of psychiatry and mentions that Kahne has "pseudologia fantastica" which is basically constant lying. In this interpretation, Kahne and Dr Zodiac are used interchangeably. We know Kane is a constant liar, for he has used many aliases.
What about Herb Caen? Who was known to actually REPORT in person at the real Treasure Island? Interesting?
