I did some digging around and I found this story that could very well be Pizzolatto's basis for season 2 of True Detective. What do you think?

The main investigation in season two could revolve around the dismantling of public transportation trolley lines by National City Lines, Inc. (NCL) beginning in the 1930s in what is also known as the Great American streetcar scandal. The contracted transit company NCL was a front company—organized by General Motors' Alfred P. Sloan, Jr. in 1922, reorganized in 1936 into a holding company—for the express purpose of acquiring local transit systems throughout the United States, but once NCL purchased a transit company, electric trolley service was immediately discontinued, the tracks quickly pulled up, the wires dismantled, and General Motors buses replaced the trolleys. Land around the Los Angeles area was also a hot commodity due to impending freeway construction.

Other wealthy individuals were also involved in this scandal, one major player being a Los Angeles judge who was also the silent owner of Cloverleaf Industries, which bought out the Pacific Electric system of trolley cars in 1945.

After Marvin Acme, the eccentric owner of a large tract of land (as well as the original Acme factory, yes, there was a real Acme factory!), near what is today central Los Angeles, was found dead of very mysterious and grizzly circumstances in 1947, his will was never found though he most certainly had one. A close friend claimed that Acme’s will stipulated that the ownership of the property should pass to the residents of his land, an isolated group, which many in the surrounding areas believed to have mysterious and inhuman abilities. The judge, despite (or perhaps because of) being born and raised by this mysterious cult, began using his power to not only keep those residents from owning the land but to remove them from the land altogether. On the business side, his company made an offer to purchase the Acme factory, which, while not located on the land in question, was being sold to the highest bidder in a package along with the land due to the lack of a will and legislation passed by the judge himself (legislation which was repealed just a few years later). On the private side, more dead bodies began to show up in grizzly and unexplainable murder scenes, many involving acid, which were mainly kept out of the press by the Judge’s ties to local authorities.

I won’t reveal everything that happened, you can read up on it for yourself if you want, and I’m sure some things will be changed around by Pizzolatto, but I think it’s a safe bet that this is the basis for the story we’ll see. The question that still remains, though, is who will play the two main investigators?
