Robert Durst

There were actually a total of eight prosecutors who worked on this case at different times.

We also had probably a total of close to 50 law clerks.

It was very clear from the beginning that these three cases were interrelated, and for the jury to properly determine the truth, they were going to have to get the whole picture.

We were trying to get the jury to understand that this is a guy who doesn't believe that any rules apply to himself.

That's just Bob Durst.

He's the most self-involved person I've ever seen.

So the trial in Los Angeles is high stakes for both sides.

Bob Durst was already in prison for six years by the time Susan's murder trial started.

This was a man who was in his late 70s who was battling cancer that appeared to be in the advanced stages.

He was frail.

He was weak.

He was being wheeled in and out of court.

He had tubes and medical devices hanging from him.

People were wondering every day, is this guy even going to live to be able to see the duration of this trial?

So it's going to be three killings that we are going to prove.

Everything starts with Kathy Durst's disappearance and death at the hands of Mr. Durst and Mr. Durst alone.

And after that, he had to kill Susan Berman because he feared that she was going to talk.

And then he had to kill Morris Black because Morris Black knew who he was and was putting pressure on him.

All of the video that you will see has been unedited.

And that so-called cadaver note, it would be the linchpin in their case against him.
