He is claiming that Mollie threatened to call police and then he had a black-out. He is blaming the victim for the fact that he murdered her.
Not to mention "psychological blackout" doesn't meet the rigid criteria for insanity or diminished capacity anyway. I know of a case where a murder defendant had documented PTSD and other residual disorders stemming from his service in Vietnam, had been shot in the head with part of his frontal lobe having to be removed, had spent half his adult life in mental institutions due to rage blackouts/limited executive functioning, and STILL was convicted by a jury of his peers and affirmed by all appellate courts.
This dude has zero chance of a "but I don't remember" defense.
