After he'd seen your partners over at Carol's and he was really scared.

And he said that at the time of Annie's disappearance. He was with someone and that she was married.

And he didn't want to expose her, and could I just cover for him. And say that he was here. Who's the woman? I don't know. Okay, Marla. Annie Miller's dead. If Derek Trainor killed her, you're an accessory. You think because I had a relationship with this amazing girl.

That it must've been perverted or violent. That's your world, isn't it?

Where grown men harm young girls. And every relationship is tainted with violence.

I found her secret stash of home movies.

You see what you wanna see. We found her underwear in your washing machine. We know you weren't at the restaurant that morning. And that you asked your bartender to lie for you. I've already lost Annie and Carol. I'm not gonna let you take anything else away from me. I am innocent. I haven't done anything. Who's the woman? Marla told us you were having an affair. We need to speak to her if it's true. I can't tell you. Look, nothing you say will go beyond this room, Mr. Trainor. But if you're innocent we want to know so we can clear you and move on. Do you think I'm stupid? I watch the news. I know what happens to people. If you have a real alibi and you fail to disclose it. You're not being heroic. You are costing us time. And you are possibly costing Siobhan her life! I'm sorry, I need to speak to my lawyer.

If he's innocent, he's making things harder on himself. We're not helping. We should've interviewed him at his house. What, do you wanna hold him? We don't have anything to hold him on. Any luck reconstructing the video? Still working on it. Do you believe what they've done to this place?

This kind of stress can bring out the worst in some people.
