when LE recreated the rope tying, all that means is that a voluntary suicide might be possible, but it also means that an involuntary staged suicide or strangulation aka murder is also possible too. Same with that black paint -that could have been smudged on her by someone else, same with the "supposed lack of other person's DNA -those persons could have worn gloves, etc etc
I do not understand why LE had to make a definite conclusion that Rebecca commited suicide when both the physical evidence, the timeline , and the bizarre aspects can also be used to point to involuntary forced or staged suicide or strangulation.
That is why, this case should be declared "undetermined". in fact there was no reason to keep the public waiting for so many weeks because the bottomline is that no one witnessed(that we know of) the following scenarios of suicide(voluntary) or involuntary staged suicide(murder) or strangulation(murder).
