I disagree. There is no way to know from the PCA which order they were murdered. Arguments could reasonably be made either way, and I remain mystified as to why it matters.
I don't think it does matter at all.
X was awake, she could have taken dog out for a walk or for company, PCA states a mere snippet.
Another permutation could be that he entered saw X's bedroom door open, E asleep there, killed him first, went upstairs, killed K and M, returned downstairs where he found X crying having discovered E's body on her return to the bedroom and then killed her.
Sheath could have fallen out of his pocket at any stage in any room.
It's a lot of headbanging when we could be spending the time digging for more info on him
finding his emails, matching them to online sites, clubs, places and people...
We're not going to get any more information until trial regarding the crime scene or the order of the killings and none of it would be helpful for sleuthing him now, would it/
He went there, allegedly, killed 4 people, allegedly, won't be killing any more, hopefully but may have killed in the past using the same methodology,
He was fast as lightening... and that skill had to come from somewhere.
People using guns can go practice at a gun range and learn accuracy.
Could anybody here say they could do what he did, in the time he did it?
And I have a feeling he knew for certain that each one was dead before he moved on to the next.
Short of actual decapitation, how could he be sure?
