what I think about it. I think darkcoug's post here
http://www.cougarboard.com/board/message.html?id=13245271 where he thinks Adnan is a sociopath makes the most sense to me. I've leaned innocent for a long time due to the inconsistencies in Jay's (J.?) story, but maybe Jay just doesn't remember all the details correctly?
I still lean innocent, but the sociopath idea makes sense due to his non-angry perspective about everything. I still don't understand why he's not more upset with Jay and doesn't try to pick apart Jay's story himself a bit more.
I don't think the state's timeline works either. She was seen by multiple people after school and I don't think Adnan did it according to the state/Jay's timeline (before 3PM). So she was obviously murdered after that time. So if Adnan was at track practice then I don't think it fits. Plus, Jay's whole Best Buy story doesn't make sense to me.
