Yes
I suspect he was going to stage a murder suicide.
Hide the kids in the tanks where he thought they would not be discovered.
Perhaps burn SW's corpse hoping to conceal the manner of death.
I am not sure how he planned to deal with her car etc. Maybe he was just too stupid to really figure all this out properly
I am now thinking that he did not plan anything. This is the issue. It was all spontaneous and impulsive.
Version one: he inadvertently murdered one of the kids and had to kill everyone else planning to conceal it. And then, in panic, hid them wherever - whatever first came to his mind.
Version two: he inadvertently killed Shanann and impulsively killed the kids as potential witnesses.
The inadvertent part is manslaughter. The other two are murders, the idiotic choices he makes that witness to his inability to think and plan as an adult.
Given the fact that he is now described as full of energy in jail, either indecisiveness is his huge issue and he feels well upon making the decision, or things in his life happen in the context of mood swings? I am thinking he had very high nervous energy after the killings since he dug the shallow grave very fast.
But I remember how the newspaper said, after his 3d or 4th day in jail, “the gravity of what he has done has set in”, and I was shocked. I thought, dude, it takes you almost a week to realize that you killed your family, your pregnant wife and two daughters?
But this is what he is, apparently. No logic, no thinking, no responsibility, the mentality of a dangerous child. And at this, someone always takes the decision for him. First, it was Shanann, then, his father.
I don’t know what function of his brain is at fault. Making decisions? Making fast decisions under stress? Taking responsibility? Something like it.
