I was 50/50 after the podcast but Jay's interview after the podcast heavily swayed me towards Adnan's guilt.

Jay was't a suspect, but definitely knew about it and where the body was.

He gave conflicting testimony to the police because he was dealing drugs out of his grandmother's house and didn't want himself or his family in prison. (Using these hostile testimonies to undermine the official one entered in court is very misleading) But he had no reason to continue lying after all these years.
