Mr. David Marks was suspected but never tried for killing his wife Katie who disappeared in 1982, but the truth is eventually revealed.

Katie Marks: My father always said to only regret the things you didn't do not the things you did. But I had an abortion and I don't know if that's something I did or didn't do.
Sanford Marks: Why couldn't you have just given her what she wanted? You're a very weak man, David.
David Marks: Look at her. I swear to God, I didn't even know that people like her existed. She's perfect.
Katie Marks: I've never been closer to anyone, and I don't know you at all.
Sanford Marks: You're ignoring a very hard fact of life, David.
David Marks: What's that?
Sanford Marks: She's never going to be one of us.
David Marks: I know. Isn't that great?
David Marks: It's not awful; it's just different. People talk to each other. And there's a ham, with pineapple on it, and little cherries on it...
Richard Panatierre: [first lines]
Richard Panatierre: For the record, tell the ladies and gentlemen of the jury your name.
David Marks: I'm David Marks.
