But this "one" example that you've given is no evidence whatsoever of a separate clean-up long after the event. The bra clearly was moved after Meredith stopped breathing with any effort - the mist of blood drops came from aspiration. But this therefore implies that the bra could have been moved very shortly after the attack took place. It's entirely consistent with the killer waiting for Meredith to stop breathing (or only breath very shallowly) before moving her bra. It's also of course consistent with the bra being moved much later on that night or the following morning, but it by no means proves that this is the time when the bra movement took place.
Ehm, the relevant part of my quote of the Micheli report isn`t about mist of blood drops, it`s rather about a huge amount of blood in the area of MK`s right shoulder, which came from her neck wound. But I can quote for you again:
"Photographs of Meredith’s body show clear white areas where the bra prevented blood from falling onto Merediths body. These white areas corresponded to those areas where blood was found on her bra.
This was particularly true in the area of the right shoulder strap which was soaked from the wound to Meredith’s neck."
I think you were mistaken from the quite unfortunate translation "...prevented blood from falling onto Merediths body.." and concluded, that all these areas had just mist of blood drops on it !?!
If you take a look at the pictures of the blood-soaked bra (there are some on the internet), trust Micheli`s ability to disntinguish between some mist of blood drops and an area overflown with blood, which originated from a large wound, then it`s obvious, that this blood came from the neck injury.
The other thing is, that poor MK, suffered an agonizing death and (sorry, I feel terrible to say that) drowned in her own blood.
So I think there`s no doubt, that the bleeding didn`t stop for several minutes, and maybe continued after MK lost her life. And now I shall believe, that RG, who definetely panicked (see the bloody hand smears on the wall and on the rack for example) waited this long time, for which reason ever, to cut off the bra? Not to mention the fact, that he knew, that someone might return home to the cottage and discover him at the crime scene during that time.
Sorry, but I don`t buy this.
And by the way, the fact, that the blood had to be dried to some degree, so that these white areas could occur, even make the time-gap between the stabbing and removing of the bra bigger.
But yeah RG surely stayed at the cottage during this time and maybe drank some coffee, before deciding to remove the bra.
