Unexpected linkages

Los Angeles Magazine has an article titled "Has The Zodiac Killer Mystery Been Solved (Again)?" about a new hypothesis for the identity of the Zodiac killer.

This comes from a researcher who started by looking at Zodiac's expressed interests:

Running other apparent quotations through Google Books and the Internet Archive, Kobek formed a picture of the killer as a fan of pulp novels, comics, and other nerdy touchstones. Kobek knew a bit about the early years of the sci-fi and fantasy fandoms, how these nascent communities had begun taking shape around an array of obscure self-published zines. On a hunch, he did a quick web search of “fanzines” and “Vallejo.”

And then all of a sudden the article is linking to fanac.org and bringing up Tolkien and the SCA (described as "a group devoted to medieval cosplay") and other fannish and adjacent interests.

I know some subscribers to this blog are long-time Californian fans, so you may even recognize the name of Kobek's suspect: Paul Doerr.
