Thor, I think her purse was left in the truck bc trace evidence would have very likely been found in or on it if the perp touched it. If the perp isn't Dale, then the purse being left w/ the Hummer suggests to me that it was a crime sexual in nature as opposed to a theft.
Either a crime of passion bc of fueled hatred or else a heinous crime done to Michelle's person bc the perp saw her & wanted her. It's all I can think of.
I don't think she jetted.
Not if he wore
gloves, but then again, never mind taking valuables, why not take the purse? Consider ... he's taken
the keys,
the cellphone, and
the decals, and what is the reason for not
taking the purse? There is obviously a reason for everything, and I don't mean just within a crime scene, but in life as a whole, so the question must be asked: why not take
the purse? If it was DS, then taking the purse makes sense ... a robbery turned tragic may be? Surely the absence of the purse might conceivable indicate just that possibility, no way one could exclude it absent evidence to the contrary no matter what one's own hunches might be, so
why not the purse? And
why take the keys? If you're DS
why not leave the doors unlocked and the keys in the ignition? wouldn't you prefer the Hummer stolen? The purse and its valuable missing may be traced by the police somewhere totally disconnected from himself? So again, he takes the keys and the cellphone, removes the decals but leaves the purse inside ...
the purse of all things??? The only item that if missing might indicate a robbery, even in some remote possibility? Why? Where is the logic in there? Where is the logic that accounts for a perp well adept in cover his tracks but then, for no apparent reasons leaves a purse, untouched inside the Hummer as to proclaim to the entire world that whatever this is it's definitely NOT a robbery gone bad of a person in a very expensive vehicle, NOT a crime of greed but one of targeting a lone woman for kidnapping and possibly rape and murder ... or if DS ... a crime of passion where he's the perp? Why would he do that? No, I think he never enters the Hummer, he doesn't need to, doesn't want to, doesn't have the time to "clean" the Hummer, that is why the vehicle is found clean, that is why, where the issue is of possibilities, then the most likely one must be IMO that Michelle herself parked the Hummer at Walden's Circle.
This perp is methodical, all indications based on
facts are that he plans and he executes, he manipulates specific events and objects relevant to those events, he's not careless, he doesn't act in vacuum, he's adept in concealing and therefore he seems to have a clear idea about what to do .... I think the most of us more of less have the same hypothesis about the value for him in manipulating
the decals,
the cellphone,
the Hummer and its keys but why
if he was inside the Hummer at any time did he do the following:
1) Leave the purse untouched inside the Hummer 2) Lock the H3 after ditching it.
As per this post and two others above IMO those two points above are inconsistent with the perp ever being inside the Hummer for more then one reason as indicated ...
Now, let's go back to DS ... if he's involved the following must be true IMO
1. DS kills Michelle in a fit of rage at his condo, on and around 4pm, in broad daylight, when people are reasonably likely to be coming and going right outside, with his own kids on and about of what would be the initial crime scene, when he would be guaranteed to be the number 1 suspect having been the last known person to have seen Michelle alive ...
therefore one must conclude that he's reckless, highly emotional, impulsive, and not particularly bright ... and that is to name a few.
however ....
2. DS manages, to remove his kids from the scene, hide the body where it's not found for more then year as of today, all by himself manages two vehicles with one of them being Michelle's hummer, or successfully manipulates others to be accessories to murder "on the fly", gets rid of the Hummer leaving no evidence behind, manipulates objects to achieve objectives, manipulates all potential crime scenes, again systematically getting rid of any potential evidence.
therefore IMO one must conclude that he's calm, calculating, purposeful, cunning and of course ... particularly bright, and that is to name a few.
So let's review some adjectives that one
IMO must ascribe to DS if he's responsible:
Reckless, highly emotional, impulsive, not particularly bright, calm, calculating, purposeful, cunning, particularly bright ... and he must be all of those within a span of a few hours.
But what does any of it say about where Michelle actually is whether the perp is or is not DS? Dunno really, unless local people go and actually search for her and don't give up. As per my most recent posts I have become more and more interested in the area surrounding Walden's Circle, I know the police have searched it, but I don't know to what extent and for how long ... I'd be looking for small objects on the ground that might be conceivably missed ... a set of keys perhaps, anything .... anything that could help bring Michelle home I suppose.
. Michelle is what brought me to Websleuths to start commenting. I thought for sure this would be a solvable case and she would be found and the rest would be history. Not so. Perps are smarter at hiding bodies and know just as much about DNA as anyone else does. Watching her on PC, the case really stuck with me; so much so I told a family member about it before knowing she was missing. While I was watching, Michelle was still around
