After a quick refresh about some facts now i've come to a very huge theory about the "killer/Clyde" and the secret organization that's called "The Oharinger Foundation".
Savannah's and Clyde's mother "Beatrice" was having a black lover and they fall in love but Paul (her husband) did catch them in their bed and killed Beatrice,then he catch and put her lover in some basemant and then when speaking with his son "Clyde" he tried to mix with his head saying it was her mother's lover who killed her and decapitated her infront of him but when Clyde got to the basemant to face him he find that it was actually his father who killed Beatrice,but the fact that there was a chance for her to start a new life with her lover and leave her familly was enough for him to kill the black guy and start his changing into the killer he is now,he even killed him the same way Corey was killed - and of course his attitude to Savannah and everyone else did change drastically.
After the last update we can see that Paul (Savannah and Clyde's father) is still alive,not to mention that a bit earlier Savannah did mention to Gretchen that after her father did buy the whole franchaise the name of the bar was renamed once again to Hooters (when she make her replace her at her shifts there).
The Oharinger Foundation has eyes everywhere and a lot of resources and connections and they have something against everyone. The killer seems to also have a eyes everywhere and the only way he can so easilly find dirt on other people,hack their phones and know which person slept with which one(in that case which girl slept with black guy) is by using the resources and connection of the Oharinger Foundation and since we already know Clyde is the killer i'm pretty sure that his and Savannah's father Paul is pretty much the "head of the table" in the Oharinger Foundation(probably that's how easilly he did find his wife was cheating on him with a black guy) or at least one of the top ones that ruins it and that allows Clyde to easilly have access to everything (after all Paul did buy a whole franchaise and did buy Savannah a pretty expensive car for her prom - means he has plenty of money).
Monty and Taylor Swift also seems to be part of the Oharinger Foundation although is not sure if they was blackmailed to work with them or they was one of the first people aside with Paul to create the organization. Taylor even said to MC that they already have the footage from the cameras where he did try to kill Monty which means i was right about there was cameras and there's really a big chance that Monty did see the footage on his phone and called the Oharinger Foundation to make it look like he really was killed and everyone believes it (after all MC did not have a card for Monty's room in the hotel and Monty will not leave his door open just like that - he probably left it like that on purpose to see if MC will be back and what will do and probably only pretend to be asleep - he survive so long by been smart,no chance he will be so easilly killed by some idiot like MC).
There seems to be another killer but it's not sure if he is just some random obsessed psycho or if he is actually hired by Clyde and working for him been his eyes aroung Gretchen(since he seems to be always at places where she is - we did seem him killing Roderick in that last update).
I'm pretty sure Paul is the one or one of the ones that rulles Oharinger Foundation and now i'm 70-80% sure that Monty is still alive but guess will need to wait to see if my theory will be 100% right.
There are some pictures of all this facts,but it's better to play it from the beginning so you can see all of this conversations/memories
