Good post. I too think that the day of the week is significant. It may be due to the perp's schedule and availability, or echoing the tactics of politicians who release bad news on Friday afternoon - knowing that LE resources would be stretched thin over the weekend, etc.
As I have read and thought more, I think there may be something to the theory that this perp may have acted when he did due to opportunity (e.g. significant other/family left town for the weekend.) I still don't get the sense that Jessica's body was placed in that location due to a lack of time.
I believe the perp had a connection to or spent a lot of time in this area - I and selected this location because he felt comfortable and believed it would enable him to taunt LE while avoiding apprehension. I would guess that the perp contemplated the crime while at the location and possibly had even pre-determined the precise location.
In my opinion, this crime was perpetrated by someone who reached a "tipping point" and advanced very rapidly through what might be considered a typical progression in this type of behavior. For that reason, I would guess that the perp has probably exhibited extreme behaviors (depressive or manic) in the days sense Jessica's disappearance - so much so that it would be difficult to conceal despite his best efforts. I would imagine that he has elected to avoid social interaction as much as possible and probably has missed work, appointments, etc (as per the FBI.)
As I previously mentioned, I believe this state of mind will cause the perp to abduct and kill again in the very short term and/or contact or otherwise taunt LE. If so, the perp may be relishing the opportunity to "watch the puppet dance" OR he may find comfort in keeping LE (and thus the MSM and public) active and information on the investigation flowing. I believe that the perp's extreme behavior in response to this sudden escalation and submittal to psychopathy will ultimately betray him; my hope is that an engaged citizenry will now report strange occurrences which they would have let slide prior to last Friday.
