Glad you're back.
The driving around thinking of a hiding place is something that's bothers me, I don't think most people would have in their minds a place that they could go if they needed to hide a body so if we imagine ourselves in the position of someone who somehow ends up needing to do that, what would be the sequence of events.
Firstly I'd say there's got to be an "oh **** what I have I done" moment, then an internal (or maybe external) conversation, "shall I call LE, shall I just run, shall I hide the body and all the stuff", if you decide to hide everything it's going to take a while to think if where to go, go there, get sorted, get home, get cleaned up.
My questions are where is this happening, by the side of the road?, at home? in some other safe place? and how long does it all take?
While I don't see any other likely perp than EA the logistics and timing of it all is puzzling me.
