Lester Holt

You said some pretty bad things in those calls about...

Patrick, I'm never going to be able to rest and be happy unless he's just somehow gone.

You talked about using a silencer, you know, that he's allergic to shellfish.

Maybe it could look like he had an allergic reaction and died.

Yeah, those were all things that James brought up and he made me believe.

But in my head, you're going to understand my mental stability at that point, too.

That plays a big part.

I've been on medication most of my life.

Allison, you do know what was said on those calls looks bad.

Just because it looks bad doesn't mean that that's the whole story.

And people need to know what really happened.

People need to know the manipulation.

In Illinois, the charge against Allison was about a theoretical murder.

But as for the actual murder in Texas committed by her ex, Delbert Mills?

That was a horrible, horrible situation.

Delbert is...

probably the worst human being I've ever met.

The family says you started this affair before Patricia Lee died.

See, that's not true.

We didn't start seeing each other until...
