Or it could just be that it's hard to sleep in jail. Also, this wasn't an actual court appearance where he would have been able to stand tall and appear confident. I believe that when an appearance is by video, the camera is stationary and tall defendants may have to stoop or hunch over to be seen properly, which could affect how confident they might seem, I suppose.
I have to disagree that this whole crime shows intelligent planning. I think it is actually the complete opposite, because I think that if someone really wanted to kill a random stranger and had all the means and tools and properties available to him that DM has, he would not have: picked a victim that would have been missed immediately, have made an appointment to kill that person using traceable means such as a cell phone, would not have gone to the door and allowed himself to be seen, would not have gone undisguised by even a hood, would have had the victims meet them someplace else, would have had a licensed second driver on hand to transport the second vehicle, would not have killed the victim in the vehicle if they planned on using it further, would have used the incinerator in a place where it could not possibly have been seen by others, and would have also stored it in a far less noticeable place, would have burned the remains to completion, and then would have gone up in a plane the next day and dumped the ashes from the air like you would with a loved one so that there was never a trace, and would have taken the truck to his own personal chop shop if that was really what was going on at the hanger (which I personally still doubt). Even someone with a less than average mind would have been able to plan better to cover this crime with all those means available to them, so I disagree with the idea that this was a crime showing intelligent planning, or any real planning at all. This does not seem even premeditated to me, more like a cover up after the fact.
I think many people will read whatever they want into the smallest details if nothing else is available to them. I really don't see how a sentence about how tired someone might look to one person can be an indicator of the inner feelings another might have, that can then be used to determine their guilt or innocence when read by a third person, in my opinion. Perhaps someone who knew the accused prior would be able to tell us if his whole personality has run into a brick wall since his arrest, but without that actual knowledge of his actual personality,mother and now, we can only make guesses or uneducated assumptions, since all we really seem to know of his personality comes from a few people who might have known him peripherally, as filtered by the media. But I personally think that spending that amount of time in jail, especially as a first time, might take a toll on anyone, I don't really think it is remarkable, let alone an indicator of anything.
