Dr. Bethany Marshall

I don't know if he's a sociopath.

But let's see, theoretically, if he was, the mother would likely have noticed many things.

But we know that this guy was supremely unhappy.

He was so unhappy, he couldn't even follow through with a scholarship.

So unhappy that he can't even smile when he gets the scholarship.

Nancy, this has nothing to do with his upbringing or his family.

I can say that fairly confidently, even without knowing them.

This type of disorder is what we call psychobiological, meaning anxiety.

To break it down, there's something wrong with his brain.

If you did a brain scan, you would probably see that there's a quieting in the part of the brain that's responsible for empathy.

You might even see like a co-worker syndrome of bullying other people and wanting to be in a one-up position.

But Nancy, this guy was not functioning normally.

He was on top of that building, sweating, depositing all this DNA.

In the text, we read that he wants to take the secret with him till old age.

So he actually thinks he's going to get away with this.

Nancy, I'd love to talk about the idea that he thinks that what's on the bullets are a meme.

A meme is a joke.

So he's already minimizing the severity of the alleged crime.

A meme is something that goes viral and everybody sees it.

So there's this fantasy of being famous, like being some kind of a hero.
