investigators, we'll offer investigative suggestions for their consideration. And that's the reality

of this kind of work. We can't solve the case in an hour, and we may not be

able to even provide definitive answers, but we hope to help focus an investigation. And although

this is the last episode on Bill's case for now, you'll see that the work isn't done yet,

Heidi. Want to move on to the suicide theory.

Okay.

So I think another strong possibility, well, first of all, let's wrap this.

So in terms of this and in terms of potentially Bill meeting with foul play, certainly
