I don't recall hearing that DR spoke to LE about drugs, but I do remember reading an article (maybe the Indiana Monthly one) where JR said that either DR or LS told him they'd snorted Klonopin that night. I remember the discussion here re: snorting vs. orally ingesting. Whether DR confessed to as much hasn't been made public as far as I know.
I do think that going more public, i.e., taking a LE-administered poly and searching for LS, may have given him a lower profile. But it's also true that he wasn't with her while at Kilroy's, which changes his involvement, IMO.
What's interests me is why JR called DR that morning. It's one of the things that makes me wonder if LS may have been ODing or having a long QT attack that was mistaken for ODing. That makes sense to me if DR or LS did indeed tell JR they'd snorted Klonopin. JMO.
Thats what I remember too, but I wasn't sure if something had slipped by me.
I agree with your last paragraph completely. I also wonder if maybe JR called to say "Lauren is ****ed up, I know you two did xyz so this is your responsibility" or something of that nature. The very cynical part of me also wonders if maybe by that point Lauren had already passed away and JR was calling DR so that after the fact he could play the good guy and say "well, I called DR to come get her, but he didn't and she left"
