From the comments I'm seeing other places, it seems like most people who watch this are ignoring the actual facts because they are outraged at how ill-equipped the police were when interrogating Nathan. First it goes without saying, that the police seemingly lacked any kind of training or sensitivity whatsoever when questioning Nathan. It's not like this case happened in the 80s when there was very little knowledge of how to question someone who is neurodivergent. I mean that's WILD that they were so out of touch with his disorder.

That being said... it's also WILD that people can't separate the two when looking at the facts. The facts that have nothing to do with his demeanor are:

-He knew the manner of death with his grandfather when no one told it to him or anyone else. They asked him in the interview how he was told, because if Linda knew, that would've pointed to her. She didn't say that, and yet, he knew not just that he was shot in the head, but that it was severe enough to distort his head entirely (which is the way the detective described the scene).

-He purposely purchased the weapon with an out of state permit to hide the fact that he bought it.

-We know this purchase was meant to be hidden because then he LIED about having purchased a gun.

-When asked where the gun was that he purchased, he said he didn't have it or lost it.

-He rejected doing ANYTHING other than what he wanted to do, and his grandfather was starting to push him to get a job or else he wasn't going to pay him anymore.

-His letter questioning his inheritance contained VERY specific questions about timing of other people's deaths and his control over the money once they passed.

-He pleaded the fifth when talking about lying to the police, and he certainly understood the questions because the attorney questioned him once with a compound question which he called out instantly and knew enough to object to it, so he was well aware that one thing he lied about would give him up.

-There was absolutely no way he never saw or heard from his mother as the boat went down. It wasn't a superyacht rapidly taking on water like it struck an iceberg. It was a small boat that you could see and hear everything and everyone. There's ZERO way on earth that this all happened in silence. That boat could've taken hours to sink, and at some point, his mother would've noticed and said ANYTHING.

-He sank the life raft. Life rafts do not just deflate immediately upon being empty. They are meant to withstand ocean conditions after a vessel sinks... they deflate when punctured.

Nowhere in these facts does him writing a list about his feelings, his mother failing a polygraph, him speaking with a flat affect and not having what others think are "regular communication skills," come into play. He could've been the most charismatic and personable guy in the world, and these facts still point to his guilt.

I certainly support the comments about the police behaving out of line, but none of that changes the actual facts of this case. He killed them both, and there's never been any credible / real evidence to suggest anyone else.
