Dr. Bethany Marshall

This is a metaphor for what he's been doing for the last 10 years, applying pressure, releasing it.

applying pressure and and remember nancy when he's in that house he is gathering evidence that she is with another man it could be baby clothes it could be sex toys it could be a diary it could be anything and he is going to

apply that pressure again.

And with the kind of obsession that I believe he has, he needs to get rid of her so he can get rid of this painful way of operating in the world where all of his thoughts go to her.

And there may be the sense that it would be a relief if she was no longer around.

What does it prove?

Simmering resentment and rage.

Rage that has been building ever since she left him.

Nancy, we know women are at the greatest risk for homicide.

As they are leaving a marriage, a woman can be stalked by her husband while she is in a marriage.

In fact, the majority of stalking happens during the marriage and not afterwards.

So in his mind, he's been thinking about this for a long, long time.

Nancy, and the fact that he's a surgeon, people who are this bright, who have this much accomplishment, advanced degrees and education, it becomes a thin veneer of sophistication.

that hides a very, very dark interior.

But remember, he had all those malpractice suits.

So he may have that doctor's lab coat.

He may have all those degrees.

He may have all of that.

But underneath is a very, very messy, and I'm going to say dysregulated person, which goes back to all the multiple gunshot wounds.

This was not just cold and methodical.
