i dont think he has any guilt or remorse. My opinion, he still feels betrayed. he isnt a POI, but if one did commit such a crime, they would probably take the victim somewhere they're familiar with or scouted previously.. because of the presumed short amount of time one had to get rid of a body. I'm however starting to believe there was a 2nd person involved.You must be hungry. ; )
To keep this on topic or it will get deleted, what is your best speculation on where May will be found? Here's my line of thinking....
LM portrays himself as very religious. If this is the case, unless criminally insane (which frankly, may be), he would be feeling intense guilt and remorse. (Even if he thinks May was a wanton women). As such, I think he would take her somewhere that she/they loved. Some place that had meaning to her, and to them as a couple. Her sister would likely know where those general locations are.
It's just a matter of time...
Amateur opinion and speculation
Listening his interview again, although sounding like he cant get his story straight and having a bad time influencing the listener, he does sound confident that he doesnt know where his wife is. I guess i would be too, if I hired somebody to do the dirty work while i turn a blind eye.
all MOO. all amateur speculation!
