What bothers me: Being part of the IU student community, then and last year, would give JW an edge, IMO. If there was anything to hear, I'd think he'd be the one to hear it. He's obviously on the outs with CR and probably MB and JR ... but still. And he has a doubly vested interest, being LS' boyfriend and a POI. Maybe that made him an outsider after the fact?
Also, since we've now read that LS allegedly did Klonopin with DR, I'd assume that JW knew she had access to that type of drug. I'm not insinuating that she was into that culture ... just that he probably knew where it came from. IDK ... my kids sometimes tell me more than I want to know about what goes on in our little town (though I'm glad they're up front and honest). Just saying.
From that perspective ... if DR was the one she did Klonopin with, why would the others be so worried about her ODing? That makes me question what really happened to her. Unless they added something or somehow (i.e., provided it) to the mix? Just thinking aloud ...
