So, what's the story? Girl meets bridge. Girl meets bullet. Then girl meets river. I love a happy ending. Any idea how long ago? It's hard to say with the bloating and decomposition. Three, maybe four weeks. You didn't find any ID floating around, did you? Nah, just the clothes she went in with. Looks like somebody did a number on her face. >> Something more likely. Fish. They go for the eyes first. Karen started with the office's upstate division 5 years ago as a paralegal in Mr. Conners' bureau. When did she get the bump up to investigator? I signed off on her promotion only 6 months ago, which is what makes what happened such a waste. Karen was something of a project in the bureau. Project? Well, it was obvious from the beginning that she had a real feel for the work. It all came naturally to her. Karen just lacked some of the formal training and education she needed to move forward. Eventually, it all came together. You have any working theories? Had. Till her body turned up in Manhattan. We have a witness that puts her in the Albany train station at 9:30 that night. And confirms her brother's story that she was taking the 6:45 from Manhattan. Timing worked. Looks like Conners was right on. From what I'm seeing, there's nothing life or death in these case files. Hey, uh, when did Conners say Karen got her first field assignment to the big city? Couple months back. And her brother thought she was still getting her bearings around town? Right. So, how come she's got three Amtrak ticket stubs, round trip, Albany to New York, going back more than a year? She goes down to the Big Apple, she keeps it from her big brother and everyone else in her life. That can only mean one thing. Uh, special friend? Mhm. Karen had no time for boyfriends. She was so busy with work. God knows we tried, but it's always one thing or another. Even if she had a boyfriend, she wouldn't have told me. The age difference, it was more like a father-daughter thing with us. Karen was seeing someone. Did she mention a name? She told you that? She didn't want people to know. We're people. Did she tell you who she was seeing? No. But he was married. Hotel restaurant charges from all over the city last 10 months. Busy girl. Up until a month before she disappeared. Right about the time Sis says the romance cooled. One, two, three, four, five visits to Caverna? You know it. Yeah, it's a quiet little place over on 21st and 10th. These gentlemen are with the police department. They'd like to see if you could help identify photographs. >> chef. Absolutely. Ah, see. La signorina Hall. She used to come here with her gentleman friend. But uh not so much anymore. You wouldn't happen to remember this gentleman friend's name? Oh, sure, sure. First rule of restaurant the business, huh? Never forget a name. It's um Al- Al- Alfredo. Uh no, Arturo. Alessandro. No. Alec. See, Alec Conroy. Alec Conroy? I killed Karen Hall because I was having an affair with her, then stonewalled the investigation. >> [laughter] >> It's absurd. Is there another explanation? Yes. The investigation into Karen's disappearance went nowhere because there was nowhere for it to go. It's as simple as that. Especially not with a cover story about a witness in Albany. The newsstand vendor told the troopers she was there. I relied on that. They don't see it that way. Really? Well, their activity reports say they do. Activity reports you supervise. I have the distinct feeling that somebody's about to read me my rights. Do you need your rights read, Mr. Conroy? Off the record? Okay. On the record then. Karen and I had been involved, past tense. I broke it off. End of story. I assume you can tell us where you were the night she disappeared. We already know it wasn't in Albany. I wouldn't have taken it on faith, either. I was with someone else. Not your wife. My wife and I weren't together at the time. I had my own place. Now, if that offends your longhorn self-righteous sense of right and wrong, then so be it. What offends us is withholding information from an investigation. If I go public with my relationship with Karen, I jeopardize cases, maybe even my career. I wasn't about to do that. Not when I had an alibi. We know you received a letter just like this one. Alec would never harm me. Karen Hall made the same assumption. Ask yourself this, Ms. Warner. When this trial is over and Alec Conroy doesn't need you anymore, are you going to go out on your boat with him again? I'd known Alec for 12 years. You described your relationship with the defendant as passionate. Passionate. Supportive. Supportive how? Alec was not a man who found it easy to let his guard down with others. With me, it was different. He trusted me. He confided in me. And that night he confided in you? Alec asked for my help. He needed to use the boat. Those were his words, use the boat? Yes. And I let him. I let him throw that girl's body into the river. Objection. Sustained. Thank you. Nothing further. Doctor, please read the highlighted portion in the third full paragraph on page two. In the light of this, Ms. Hall, I believe that Mr. Conroy should be considered an immediate and very real physical threat. What was the basis for your opinion? Mr. Conroy suffers from CDR, control domination response. In lay terms? He needs to feel that everything in his life, especially the people in his life, are under his control, domination. Specifically? Just look at the women in his life. Devoted wife, widowed mistress, aspiring employee. All of them share a vulnerability to him, a dependence. When Mr. Conway realized he could no longer control Ms. Hall, you can see how her defiance could be perceived by him as jeopardizing more than just their relationship. Did he say he was going to kill Ms. Hall? He said he wanted to. And I believed him. Nothing further. For months, Karen Hall's family has been plagued by questions of how and why. We're not leaving this room until your client answers them. It's okay. You know, this may come as a big surprise to all of you, but I loved Karen. Killing someone's a pretty sick way of saying I love you. When I first met Karen, she was just another local girl in cheap shoes. She didn't know the first thing about being a professional, about talking like one, like dressing like one, or like thinking like one. I was the one who taught her that. And then you betrayed her. No, that was her choice, not mine. I was willing to give up my wife and my children for her. She just couldn't appreciate the sacrifice. So then? So then I called her late that afternoon and told her I had some new information about the case. She was reluctant about coming over to the apartment, >> [sighs] >> but I told her it would just be a few minutes. But I could tell in her voice she didn't want to come. But she did. Loyalty to the job, Ms. Carmichael. I thought of that, too. Where'd you get the gun? Alice's. A few weeks before. What happened after Ms. Hall got there? At first we talked about work. I wanted her to think everything was going to be okay. But then I brought up the relationship, and Karen said she was uncomfortable with the subject. That it was over. She started putting on her coat. I told her to sit down. She said I couldn't tell her what to do anymore. So I reached for her. And she pulled away. And she said that the [music] thought of her being touched by me again made her sick. That's [music] when she saw the gun. She gave me this look. Like she knew she'd gone too far. >> [music] >> Why not just let her walk away? I couldn't. Karen should have [music] known I could never do that. Now she does. >> [music]
