I just realized this whole time, my opinion has been both that EG lied about JO having Lucas on Valentines Day to set up (premed) and that she killed him in a fit of rage after finding out the LL saw him through the window. These two things just don't go together. So, now I'm even more confused and unsure of what I believe than ever.
They sort of can go together. A few weeks ago I was reading about people having thoughts of murder and making the plans for it in their head, some follow through but most don't.
EG could have been making those plans in her head and then the LL thing could have been something that made her lose her desire/ability to hurt Lucas without killing him.
What confuses me is that EG didn't seem to mind anyone seeing Lucas with bruises. What could have been different this time that stopped her taking Lucas to the ER and saying he fell? If it's fear that he might survive, she can technically wait until the next morning and claim it happened while she was asleep and he must have woken up in the night and .... From the VD example her lies don't seem to need to be very reasonable in her mind.
Thinking about it as I type it, one difference might be that this time she had lost her desire to hold back and this time she was willing to go for the kill. That in and of itself might change her internal ability to take him to the ER, even with a bunch of excuses.
I don't think most people are really thinking about things like decomp, I think mostly there are two main facets...one to get the body away from themselves/their home, and two to have the body out of sight of anyone passing by/combined with the need to be secretive and unobserved in the dump itself.
Even if EG was thinking about pointing the finger of suspicion onto Jamie, EG isn't Jamie, she's EG. So she can only go so far in this train of thought, so she might theoretically think of a place like near the hand-over point, or somewhere around El Dorado, but she's not looking for a place that Jamie's intimately familiar with per se, she's looking for a place that's loosely connected to JO but also a place that she knows or a place that just stands out to her as a good hiding place and it's maybe within a few miles of El Dorado? I think a place in El Dorado, or the vicinity, that EG is familiar with is fine, it doesn't have to be somewhere that Jamie is closely associated with, only a loose association for Jamie will do.
I really think that the necessity of removing the body is the prime motivator, not thinking about trying to get into the scapegoat's head, and I don't think that someone in the position of needing to dump a body can fully think through how to not point at themselves in their choice of place, I think the prime motivation is "get rid of the body/hide the body".
I do think that some form of premeditation ought to make someone more likely to want to do a good job of hiding the body, not so much dumping by the side of a road but wanting to find a hiding place. And looking at G maps of Wichita that seems to be a very hard thing to do. I would love it if someone could look around and look for all the possible dump sites and then look again and look at where you wouldn't dump a body (but still with the usual caveats of hidden, not feeling overlooked as you do the dump, and not physically visible to anyone waking or driving by. Big open fields and narrow tree lines just doesn't feel like it fits the bill, but I don't know what could?
