Yeah, the religion as a negative is probably going to be in this. That church is involved in some way. The preacher made the cross backwards during his sermon. They don't put stuff like that in the show unless it means something.
It's obviously a coverup inside the department and government. All of those missing girls were "false entries" or "errors" or whatever Rust saw in the computer system in 2002.
Also, the officer who took the guy that committed suicide to the phone before he killed himself has the same last name as the sheriff that the police chief mentioned earlier in the season. The one that was erroring out missing girl cases.
At the end of this episode when he's holding the stick figure up and looking at it in the light. The cinematography was so clutch. They zoom out through that broken glass to show the black stars on the glass and the woods painted around the window. Rust was in Carcosa.
I'm still curious about the groundskeeper from the school in episode three. Also, the Tuttle death in 2010 shortly after Rust came back to Louisiana. I'm guessing they'll address the Rust/Tuttle connection in the next episode.
Also, smart/funny of Rust to drink during their interview so that it's inadmissible.
I also wouldn't be surprised if Marty's father in law is in on the scheme (putting the foul children out of their misery) and he is the one that exposed the older daughter to the hardcore stuff she draws/acts out with dolls as a child, then eventually emulates as a teenager.
In the photo at Dora Lang's mother's house, there is a picture of Dora with five guys on a horse.
Marty's daughter depicted a gang rape in which five dolls surrounded one naked girl:
They say that Tuttle died in 2010.
In 2012, Rust made a point to have four of the five can-men he carved standing, implying one has "fallen."
