I am counting on the luggage. It must have something forensic in it..what are the chances it's brand new?
I am too christine. This does not appear to be a well thought out crime even without the TH theory of "disorganized" killer.
IMHO it looks like a crime of opportunity vs. planning, a perp that was known to the vic vs. stranger coming into the community.
Everything that we have seen so far illustrates a crime that was commited at the spur of the moment, an opportunity presented itself to this man, he had coveted her and he seized the opportunity.
The exclusion to this would be the suitcase, that shows a bit of planning of sorts.
However, we don't know where that suitcase came from and how available it was to the perp. It could have just been there at his fingertips literally.
But when I look at the suitcase as a plan to dispose of her body, then the fact that a retention pond was selected shows a lack of planning as well.
LE hasn't said if she was sexually assaulted or not. I am willing to bet she was.
One scenario that I have turned over in my mind is that this was a crime of opportunity, the crime intended was sexual assault. The crime escalated and he killed her, and then disposed of her body in the quickest fashion possible without careful planning of the first crime through the other crimes he commited against her.
Just some thoughts I have been tossing around in my head today JMHO
