I, too, am finding the media focus on the various exes very interesting... I have to wonder if they're being manipulated to get a suspect (or perhaps multiple suspects..) good and mad, maybe enough to slip up in some incriminating way.
Just thinking through the wound evidence.. three throat slashes, the medical opinion being that he was sitting down for those or in bed.. I can see shock immobilising a man, especially if he's had a few drinks and wasn't expecting the attack, and the rest of the stab wounds to his back coming after he perhaps toppled off the bed, in a frenzy of rage/overkill.
That's punishment, right there. Definitely somebody with a personal agenda. Lack of defensive wounds says to a likely 'blitz attack' - he was either super comfy with the killer being there, or didn't know they were there until right before they struck.
I wonder why the cops are being cagey about whether the front door was left open or not...
And whether there were bloody footprints or drops leading out of the house. The killer -had to- get blood and plenty of it on them, especially if they cut his throat from anywhere but behind him, and certainly during all that stabbing. There will have to a blood trail, going somewhere and ending somewhere.
I think '30 wounds' is weirdly specific, but could have been just a guess that happened to be close.
so so sad
