let's breakdown the narrative for reasons why they said what they did. Because, if the "only" crime was that they hid Lauren's body after an OD, everything would still have to be orchestrated.
So, I'm going to assume the POIs are lying. A first example would be, "why would
JR say that Lauren mistook his Ipod for a phone?" It seems like he is trying to give an example of how inebriated she was...this is how it was taken by the public.
But, to make his story work, to make his apt. the last place she was and that she left on her own, he has to prove she was there..she was there, earlier in the evening, before she was supposedly there at the end. So, her fingerprints are on his IPod.
IMO, his apt was not the last place she was. But, if the POIs want a clean staging area for their story, his apt, with evidence that Lauren was there, would be the perfect place to use for the narrative. Just in case any forensic evidence that may have remained from hiding her, he threw in the remark that he asked her how she
was injured. So if any traces were picked up in his apt, he could say it was from that, for example.
Did I say I'm just speculating? Another bit of seemingly useless info is MB's famous paper due. Like, who cares what he was doing? Does it really matter?
And, the part about putting his friend to bed.
Two things. It places him out of the room Lauren was in. And people, lots of students, snort stuff like adderall and vyvanse to "help" them study. Parents get the prescriptions for them! Who was one of the first people to chime in when people didn't believe MBs story? His mom!
If it were found out that Lauren OD'd on his adderrall/vyvanse/whatever, it gives
MB a way out--he was upstairs and she got into his studying medications without his permission. Remember he said she asked him if he wanted to party. Placing the blame on her.
The person intercepting her in the shadows may be exactly why JW is a POI. In his recent statement, JR may be underlining that for JW. Yes, they may be fraying
a bit because despite many people calling for a respite as to blaming the POIs, people aren't going along with it.
What other bits of info in the narrative could be indicators? The out of town guest tweeting from the Runcible Spoon. He was probably well out of town when someone tweeted that. If these very rich "kids" had help from the beginning from outside (re)sources, the first thing they would probably say is, get the body out of town and trust no one out of the loop. So, as Ros pointed out, what drunk kid could hide her so well here that locals looking for four years couldn't find her?
The tweet placed him innocently having breakfast, with the need to tweet about the corned beef? These guys were in the tech biz. Giving his phone to someone
would probably not place him out of the phone circuit, he most likely has more than one. I'm guessing that someone else tweeted that.
