Found a small one the other day.

I was reading an article about how Julius Kahn Playground (Where Z was potentially spotted escaping into) was renamed because Kahn was involved in trying to exclude Asians from migrating to the US.

One of the quotes in the article was:

“The people of the Pacific Coast feel satisfied that [Japanese immigrants] will always remain loyal to the mikado” and not to the US.

I was not expecting a reference to "Mikado" in a random article about that place I came across while checking out the area of the Stine killing. Just a funny coincidence.

Also another one is the fact that obtained audio recordings of suspect Lawrence Kane just happen to include him using the word "Zodiac".
