Leaving the all the controversy behind, there is one question about this case that has puzzled me from the beginning that I have not seen addressed. Simply, how can someone murder 4 people with a knife without a scream, a shout, any sort of warning let alone a struggle of some sort. At first glance this seems impossible.
Well, at risk of being a broken record, that's why I was emphasizing what SG said about Kaylee's wounds. It's in the media thread. I will post this and then edit it to put in an actual link (I posted the link several times yesterday, but this is a new thread)...
SG says that Kaylee's injuries were to her lungs and liver. People here have argued that simply cutting someone's larynx would cease all speech (it sort of would - there could still be moans or sounds though). No one is going to die quickly from that injury. I am arguing that this killer (based merely on SG's statements) was particular about how he did this crime. It's not hard to find instructions on the internet - I was shocked to see instructions on how to best kill someone with knife offense with a quick google search. With pro's and con's of each method of killing.
NSFW, NOT FOR THE SQUEAMISH...
SG says they were "big gaping wounds." This is consistent with manuals, books and youtubes on how to use a knife to kill humans. It's consistent with the Ka-Bar style of knife (I am not going to post those links again - surely we all know that's on the media thread and is discussed here daily). And I have a bias: I believe what SG said that the Coroner told him. This is a professional bias, just as a mandated reporter believes the victim's story, I believe the accounts of crime victims - as anthropologists treat all informants as truthful, we are not lie detectors or criminologists. So grain of salt, I guess.
So, what the killer does is destroy the lungs, not just take a small blade and stick it in and deflate the lungs. If the person is lying down, they may need to be repositioned (hence, some mention of defensive wounds). But, knife goes up under the rib cage, into each lung, wiggles around, deflates the lung (which will also start to fill with blood). No sound will be emitted by that person any more.
Why not slash the throat? Because it can be hard to do if you're not behind a sitting or standing victim. AND, it will cause arterial blood spurt and the killer gets much more bloody (I think the killer did not want to get all bloody).
Why the liver? Because the same type of damage to the liver is going to cause rapid bleed-out and death (the liver itself does not feel pain - keep that in mind;
Does the Liver Feel Pain?) I believe this explains why Mabbutt said "they didn't suffer" or similar words. Striking a knife into bones is much more painful (and the muscles overlying the liver would feel pain - but IOW, it's less excruciating than it might sound. Some online guides mention this as a more humane way of killing. Just saying what I found online, don't come at me - I believe the killer went online (probably at the university library).
So with 3 intense strokes per victim, with the blade held saber style (not in what is called the "stabbing" grip by some), the blade would not catch on bone or cartilege (or be unlikely to), victim would be silenced, then bleed out. I personally believe the killer knew this so well that once this was done, he moved on, knowing that person would die and not waiting to necessarily to see that they were dead. He knew they'd be dead (and he was masked, anyway IMO).
THAT is why I brought up SG's words yesterday. I think SG is emphasizing those organs for a reason. If it turns out that all four victims have similar injuries (even if Kaylee's are worse), then I am betting an actual donut that the killer had a plan in mind to silence and cause exsanguination before he ever went inside. I am not betting the whole farm - but I'm willing to put the THEORY out there.
The father of slain University of Idaho student Kaylee Goncalves said the victims had "big open gouges" that were clearly the work of a "sadistic male" and called police "cowards" for not sharing more with the public.

(And if SG is correct and the wounds don't match, then I would assume MM was killed in a different manner, perhaps because the killer couldn't get into position to use the same method). I am ready for the autopsy results to show either thing (just KG had lung/liver wounds or that all did - or that any subset did). But I am betting that lunch money ($0-1) that at least two victims had the same types of wounds.
Here's an article on just how dire severe liver injuries can be, even if the person gets to the OR relatively quickly:
ies, were due to exsanguination. A critical analysis of the specific surgical techniques used for hemostasis was undertaken. Hepatotomy with subsequent direct vascular and/or biliary duct repair or ligation was used in 44% of the cases and was successful 87% of the time. Hepatic resection was...
