She sounds like a kook with violent tendencies. He probably couldn’t take it anymore and killed her.
I'm writing a novel now with just such a premise; the wife berates her poor husband until it graduates to violence, and even that doesn't move him until she starts belittling his manhood. At that point:
There was nothing for it now. The whisky bottle, by the merest chance, stood right at hand. With a single rapid move he seized it by the neck and brought it crashing down upon the frenzied woman’s head.
Maybe. Alternatively, she could have been a victim blaming his actions on herself so that the cops did not arrest her boyfriend. And a lot of victims do believe the abuse they suffer is their fault. They have low self-esteem and don’t want to lose their partner, no matter how screwed up he / she is. Sorry if I sound like Phil Donahue. Not enough coffee yet today.
He is mentally ill too .
He was gaslighting her to justify killing her .
He took her van and hid at his patents and they are blocking the police with her stolen van .
Where some of those pics were taken, a slip and fall can easily be a fatal accident.
Pretty certain that is the story he is telling the cops. “She flipped out and wandered off... I looked around for a couple of days and figured she was gone one way or the other.”
Yep. He has a scratch mark on his face, too. He lost his cool and killed her is what I think. Sad, he should have just walked away.
Possible alternative - she is crazy enough to take off on her own.
However, I will admit that I dont have enough information to draw a conclusion
