I agree that I'd think there would likely be some evidence of jealous and/or possessive behavior in the past but I don't think we'd know about it unless an official source would want to share that (and that is simply an area that really hasn't been discussed one way or the other in the normal outlets). Not hearing about it simply means the question of its existence is unanswered IMHO, not that it doesn't exist.
As for the length of time he would've had to have been stalking and lurking that night, it doesn't have to be a long length of time. The area where he might expect to find her is fairly limited, especially if he had suspicions that something was going on, so it could all be a matter of timing for him to have seen her at some point whether that means he started lurking in the area shortly after the game, after bars closed, or whatever it could've been. He could've been on his way to Smallwood to knock on her apt door for example and saw her and CR leave after the altercation.
Or, after no contact with her and no returned calls/texts, he could've been on his way to confront CR at his apt to see if LS was there with him and witnessed her leaving JR's. No hours upon hours or searching and spying necessary.
None of this is to say that scenarios like these are the most likely scenario of what happened, just that it can't be discounted without more info that answers several questions about their relationship and his alibi for the night.
The media (and Spierers for that matter) quickly focused on 5N. Perhaps for good reason... perhaps solely for the obvious timing issues.... or perhaps because LE didn't share some potentially exculpatory evidence. Since LE has been so tight lipped in this case not hearing about these other avenues of possibility to me simply mean they are unanswered questions. Not that it means they are avenues that are settled and there's nothing to discuss.
We're discussing whether or not JW should be excluded or lowered down the list of of potential suspects based on the expectation that someone would've needed to inform him of the happenings of the evening versus the likelihood he'd venture into the night on his own with a hunch.... And the truth is we can't even say for certain he didn't get a phone call, text, email, or late night visitor. LE almost certainly wouldn't have shared it if he did. Let alone, the possibility they don't know themselves for certain.
