So just 2 or 3 were questioning AK and not 12. RS dropped AK's alibi, and AK suddenly accused Patrick after they discovered her text message. RS never said she had gone to the cottage. The police didn't ask if she was at the cottage (They asked if she went out to meet Patrick). How in the world did she imagine that she was at the cottage hearing Patrick kill Meredith?
Guede, Knox and a couple of neighbors all heard a loud scream. They independently reported this information, without corroboration. I don't think that there can be any doubt that Meredith screamed loud. Guede, Knox and a neighbor independently reported that more than one person was involved in the murder. Knox knew that Meredith was near the closet and that she bled to death before there was a public report. Meredith was under a duvet and, when the bedroom door was opened, Knox was in the kitchen, next to the exit. In fact, Meredith had died near the closet (blood pooling) and she did bleed to death, but she was moved, and found, a few feet from the closet, lying on her back with a pillow under her hips.
Knox volunteered that there was a scream, that more than one person was involved, that Meredith bled to death, that she died near the closet. Knox interfered with the crime scene by suggesting that Meredith routinely locked her bedroom door, and she interfered with a police investigation by sending police on a wild goose chase after Patrick, to his severe detriment.
