She was obviously charmed by this guy. How can you POSSIBLY explain how Jay knew exactly where Hae's car was if Adnan wasn't involved? Everyone and their mother saw Adnan with Jay all day long, phone records corroborate that Adnan was with Jay throughout the day, Jay himself gives all the facts about what happen and when the cops ask Jay where Hae's car is, he knows exactly where it is and tells them right away.
Given all that, how could you possibly think Adnan isn't involved?
Jay was either involved or knows who did it. Jay knowing where Hae's car was doesn't prove Adnan was involved in any way, it proves Jay was involved if anything. Also, Jay doesn't give them all of the facts, he gives them a few differrent rough outlines of how the day went down. Some of the bullet points are the same, but things change quite a bit, and between every other person he talked to the stories vary even more. We have Jenn, his co-worker (was it Carl?), Cathy, and Jay's 3 different stories that all have a lot of differences. They have very similar bullet points (basically Adnan gives Jay car, Jay drives around, Jay picks up Adnan and sees body, they drive around and get high, they go park car and bury body, Adnan takes off) but even a lot of those are changed in subtle ways here and there.
Lets look at Jay's claim; that Adnan lured Hae to a Best Buy parking lot, in broad daylight after schools had let out, then strangled her in her own car--despite the fact that she was more physically fit than him--then popped the trunk, dragged her body around and tossed her in the trunk, before walking inside of the Best Buy casually to call Jay and come pick him up. That alone might be the most ridiculous stretch imaginable. Nevermind the fact that Jay fabricated the Phone Booth in the Best Buy parking lot, and only mentioned Best Buy to the police. He also claimed Adnan took a call--that doesn't show up in the call log--and spoke in a "foreign tongue" to someone, despite the fact that Adnan exclusively spoke English. It seems like Jay told at least 1 lie for every truth.
The conversation with Jay's coworker in the last episode was pretty powerful to me. I think it is pretty obvious Jay was scared for his life, scared specifically of what Adnan would do to him and his girl.
I'm a firm believer that Jay was borderline delusional. He was described as a very off the wall person (offering to stab his friend because "he'd never been stabbed") and all his talk about being the "Criminal Element" and the fact that he mentions dozens of times various ways of destroying and concealing evidence--wiping down fingerprints, forming alibis, "dna under fingernails", West Side Hitman, all sorts of weird things that he did and claims Adnan talked about.
The jury took less than 2 hours to find him guilty. The cops are absolutely 100% sure he did it. And Jay sounded very believable to me.
That Jury was a bunch of idiots. The interviews they did with the jurors were troubling to say the least. They interviewed 6 of the 12 jurors, and I remember one of them flat out saying she held it against Adnan for not testifying (which the Judge explicitly says they can't do) and 2-3 others who say they were displeased by that fact. On top of that, one of them recalls at least 1 juror explaining to the rest of them how Muslims treat their women poorly like they are property which shows clear racial\religious bias. Add to all of that the fact that some of them were under the impression that Jay was going to serve time anyway (he didn't) and it looks like the jury was just... bad.
There is plenty of reasonable doubt, and the state honestly failed to prove innocent without reasonable doubt. They tested nothing at the crime scene, nothing on Hae's body, and in fact the few things that they did test rarely matched up with Adnan (some hairs found on her, the map book) and in some cases were easily explainable (the book had other fingerprints on it but they focused on a partial palm print of Adnans).
