I've yet to find any evidence that the twins held exceeding jealousy for Rebecca's looks, though if course it's a theory to consider.
In my mind, it looks more like sheer punishment. Compounded, as stated previously, by the police leaving her body lying there all day. It was actually smart of them to not remove any bindings prior to proper examination by an ME, that's good practice in suspicious deaths. But failing to locate ANY other ME in the entire state (or nation for that matter...) for 13 hours, and failing to erect some sort of covering to protect evidence and dignity is --and should be! - a permanent stain on that department's reputation. Gods, imagine if that was your sister. Your daughter.
It's amazing, isn't it, how many local professional and official parties seem to have behaved in exceedingly strange ways, surrounding this exceedingly strange death. We have the police dept doing all of the above, and also failing to test possibly crucial pieces of information, among other problems. Like allowing a Shacknai lawyer past the tape... We have Max's doctor filing a CPS report against a dead woman, 4 days after Max is injured, with the search warrant on the mansion sealed by police "in case" the "perpetrators" messed with the evidence... wut. Yet, as a CPS report *was* lodged, one has to wonder whether this taken into account over that "17 days" of investigation, and the process of deciding this crime should be ruled a suicide.
When you stand back and look at it all, it's plain that something's not right at all with any of this.
It's cases like this (or at least, as full of "unusual" and "inexplicable" things as this..) which in Australia tend to be the subject of Federal level inquests - sometimes multiple inquests, especially where LE or medical impropriety is a possible factor in why the case is not resolved (or is plainly 'resolved' in an improper way). They can be pretty merciless.. and don't always resolve things fully, but they surely do help some if not all of the truth to come to light.
Is there no avenue for such an inquest, in California?
Anyway, this "bigger picture" has certainly helped me understand a few things, despite obscuring others. The pity of it is, most of what went on in the underbelly of this crime is very difficult to prove in court.
