OH MY GOD THE FORUM LOGGED ME OUT AND I LOST EVERYTHING
This post might get messy. I'm trying to organize it in a way where my thoughts make sense, but it might not work.
I keep flipping on whether I think Adnan did it or not. With the evidence from episode 9, though, I'm positive that it didn't happen the way the state put it. No phone at Best Buy, the timing having to be perfect to be able to get there and strangle her from right after school, Summer having seen and talked to Hae in the gym for at least 10 minutes after school. None of that adds up.
With Jay having led police to the car, it is definitely reasonable to assume that he did play some part in the murder, whether it was the actual murder, the aftermath, or just finding out about it later. That, and assuming he was not told about where the body was found before he went to the police with everything, he could not have known her body was in Leakin Park. There are a couple of theories I have with him.
The first is if he was the murderer. That obviously explains how he knows where the body and the car were. If Adnan had let him borrow his phone for some time, he could have made/received any calls that look suspicious. It does not explain the call to Nisha if the phone was given at the time that Adnan says he gives the phone to Jay. But I'm going to skip this for a minute and continue on. Now, why would Jay want to kill Hae? Well, the best way to lie is to keep as much of the truth in there as possible so you minimize the number of made up facts you have to remember. What if Adnan had been threatening Stephanie? Maybe it was a joke that got taken overboard, or maybe it was somewhat real and Adnan is not admitting to it because threatening someone for real would not help your murder case. Or perhaps it seemed like Adnan was moving in on Stephanie. He had gotten her a birthday present that year but Jay had not really given it a thought. If this type of thing happened over and over, Jay could see that as him moving in on his girl. And that inspired him to murder. Now why would he murder Hae instead of Adnan? Well, it could be killing his girl woudl be the best revenge, maybe Jay thought up the plan that would get Adnan in jail or get him the death sentence.
If Jay did not murder Hae, then he had to have helped in some way. If it was someone who is not in the story yet, well I don't know their motivation for killing her, but I can reasonably explain Jay's motivation for going along with it. Maybe he got involved with a heavier drug dealer and fell in debt and this was the way to repay that debt. I know they only mentioned weed in the story, but every weed dealer I know has some connections to harder drugs. Or maybe it was just someone threatening him or stephanie. Maybe it was that they both had it out for Adnan, but Jay didn't have the balls to kill, just to help out.
If it wasn't a stranger, AND we don't get into the messy details of "Maybe one of Hae's friend's snapped" then that leaves us mainly with Mr. S. His story just doesn't add up with how easily he found Hae's body. I don't like it and it doesn't add up. I don't have any evidence, so I can't really say anything more on this.
I had more the first time you guys, but this took too long to type out and I don't want to go into crackpot theories that don't involve Jay. He just knew too much to not have been involved.
Any counterpoints, better theories, debunking my theories, points that bolster my theories even more, or facts that I forgot, I would love to hear!
