Ok so I made a thread for theories if anyone wants to post them here:
I mention what ski_the_east posted above. Having just rewatched the first two episodes I found a few weird things.
-In ep.1 when Rust is over at the Hart's for dinner they are all sitting at the table except for Marty and the camera focuses on the two girls whispering to each other. You can clearly hear Audrey say "He kidnapped a d_____"and they look at Marty and giggle.
-Also its important to mention Ted Childress aka former sheriff during the Marie Fontano case, who said she ran off with her father and enter the report as "Made an Error", (hmmm, like all the other ones Rust finds later). Also important to note that IMO he is Errolls' (lawnmower man) father, the one that gave Erroll his scars as mentioned by the black lady in ep.7
-When the Rev. comes to the police station for the first time he says two quotes that struck me as double meanings; "You guys have a lot of people taking care" and "There's a war behind things"
-The bar Marty is constantly going to is Elk's Bar
-Rust makes a quote to the black detectives saying "the body is not one member but many" A possible hint to the fact that there are 5 main men involved that may make up the yellow king?
-When Marty come in to get the girls for dinner you can hear them talking about car accidents (just struck me as weird)
-Marty's father-in-law mentions how kids these days dress in black and are obsessed with sex. Clear foreshadowing of what happens to Audrey
-Finally at the burnt down church Rust is looking at birds and they quickly form "the spiral". Could just be a hallucination but he plays it off as if it wasn't.
