Good post,
@kittythehare -- it just makes me wanna scream. That pretty, talented young woman. IMO, I think he may have enjoyed "playing with" her mind --
simply because he could. We have seen that here before in other WS cases, and it is a very cruel thing to do -- especially to a young, hopeful and trusting young woman, IMO.
<modsnip> I think we can rule out natural causes, although that is the way it is usually stated (as you wrote above -- murder or misadventure) since we do not yet know COD. Good write-up -- thanks.
