Lester Holt

Did Allison have anything to do with the death of your wife?

That I do not know.

I was not there.

Despite those claims of ignorance, Delbert says he does know who is responsible for the fire and has kept it a secret for more than two decades.

Okay, well, it sounds like you're blaming your son.

You have to know there are going to be people who find what you're saying right now despicable.

Mm-hmm.

Based on all the statements that you made to people about killing Patricia.

Now you're saying that you think it was your son.

Okay, why believe you?

Why not?

Because there's witnesses who have said...

That you told them terrible things about Patricia Lee and that you confessed to starting the fire?

Delbert has professed his innocence for years, but he never implicated his son until now.

If you're protecting him, why are you telling me?

You know, your son has been through hell.

And now you're saying this, and you're acting like you're trying to be this good father, that you're protecting him.

And you're not.

This is...

Well, sure, if it's the truth.
