Calluses on the fingers of her left hand, brown discoloration on her jaw. She's a string player. Natalie Dresner, 24. Manhattan Symphony Orchestra. I take it she didn't slip in the shower. >> One shot to the head. Entrance wounds in the right temporal area. Singeing and smudging. Up close and personal. But the shell casing's over by the makeup table. >> There's also some deep muscle bruising on the left side of her neck. Defense wounds on the hands and the arms. I she put up one hell of a struggle. >> Well, after he pops her, he drags her in here, covers her up, and makes her comfortable. >> Yeah, real labor of love. The cash is still in the wallet. Jewelry's still in the box. Violin still here. Anything appear missing to you? Like I said, I just patrol the grounds. Uh did you hear the gunshot? Rooms down here soundproof. Can't hear nothing from the outside. >> Any service exits nearby? Two on the basement level. All right, let's go. The hallways like a maze. Got lost a few months ago. Was howling and banging an hour before anyone heard me. Uh we'll drop breadcrumbs. >> She was killed just after the reception. You got a guest list? >> Mostly blue hairs with season tickets. Whoever did it knows his way around the place. It's like a catacomb. Are you paying any attention at all to your rhythm? BECAUSE I CAN TELL YOU IT'S TOTALLY NOT SPECIFIC. IT'S NOT JUST STAYING out of the rests. It's how you come in at the dotted 16ths. If you're not prepared to render this with any kind of precision, please don't waste my time. Sorry. I'll try IT AGAIN. DON'T TRY. DO IT. WHAT CAN I DO FOR YOU? We need to ask you some more questions. >> I knew about the solo offer. I encouraged her to take it. Not worried about losing her? I've been conducting for 20 years. I've watched a lot of artists come and go. >> Including artists you've been sleeping with? At the risk of sounding crass, she wasn't the first. Is that why you neglected to tell us? That was out of respect. For whom, Ms. Dreisner? And for my wife. Oh, she knew? Marion is an exceptional woman. I've always been candid with her. It's been 19 years. I don't expect you to understand. Do you think that he was in love with Ms. Dreisner? No, absolutely not. So, you didn't pull her aside and have a little chat about the sanctity of marriage? Their affair was dividing the orchestra. The other musicians felt she was accorded a special status. She would show up late to rehearsal. She didn't bother to review the scores. I had a bad day. I lashed out at her. Mrs. Reger, does your husband own a gun? Oh, I was raised in New York, and so when we moved up here, I was very uneasy at night. All that silence was deafening. So, Carl bought me a gun. Mind if we take a look at it? I don't have it anymore. You see, a few months ago, a neighbor's house was broken into and he was shot to death with his own gun. It just terrified me. What did you do with it? I dropped it in the Hudson River. Van Buren just called. Carl Reger has a SIG Sauer P225 registered in his wife's name. >> Oh, that's a big surprise. I found this button under the back seat. Tiny brown spots. Could be dried blood. There's also a small white fiber attached to it. There's a 2-mm spot with a microscopic pattern of blood spatter surrounding it. Type matches the victim. You get enough for DNA? We sent it out. >> What about the fiber? >> Yeah, high-quality Italian knit cotton. White dress shirt of some kind. I love it when it all comes together like this. >> The relationship between the conductor and his string section is quite intimate in the best cases. There is an implicit trust, a deep level of communication, and a shared passion. I had all that with Natalie. Over time, it led to a sexual relationship. Was there ever a violent nature to your relationship? Never. She was like a delicate flower. I gave her the freedom to bloom. I nurtured her. How could I destroy her? She was part of me. Mr. Rager, will you describe what you did that night after the concert? I went to my dressing room, showered, changed, and drove home to my wife in Chappaqua. And what time was that? About 11:30. What was your reaction when Ms. Drysdale told you she was leaving you? She never told me any such thing. So, Mr. Stern misunderstood what she told him she was meeting you to do? Either misunderstood or misrepresented. Was it misunderstanding or misrepresentation when you failed to tell the police about the affair between yourself and Ms. Drysdale? Neither. It is that I didn't want to hurt my wife. There must be some mistake. There's no mistake. We contacted Alan Bostwick, your husband's CPA. For the past 3 years, Carl's been actively selling off stocks and mutual funds. He places the proceeds into a money market account, then withdraws the cash, and then wires the transfers to an offshore account in Switzerland. No. Here are the wire receipts and your husband's passport. There are also numerous trips to Switzerland, none of which correspond to tour dates. And you thought you were broke. Yeah. Carl said we lost money in the market. That's why he hired Alan. Said he was a financial genius, that he could make up the money that we lost. Mrs. Rager, Alan Bostwick's specialty is helping rich guys hide assets from women they're planning on divorcing. Carl is not planning to divorce me. Do the math, Mrs. Reiger. $2 million socked away for 3 years and you haven't seen a penny. A year ago your husband transferred the deed on your house in London. No. We sold that house less than 3 months ago to pay for legal expenses. Look at the deed of transfer. He still owns the house. It's just registered to his corporation. I know how hard this must be for you. He did all of this for her. A girl died, Mrs. Reiger. He's now involved you not only in his infidelities but in a murder. The orchestra gave a performance on the night of Ms. Drysdale's death, is that right? Yes. Rachmaninoff. What happened after the performance? I went to Carl's dressing room to see if he was ready to leave. He said Natalie needed to see him. I told him I would wait. Was it your habit to wait for your husband while he was seeing Ms. Drysdale? I knew that Natalie wanted to talk to him about her leaving the orchestra. I knew that Carl would be upset. I waited to see what would happen. Marion, please. Be quiet, Mr. Reiger. You're not conducting here. He told me that Natalie wasn't leaving. I told him to go home. I told him that I would meet him there later. For God's sake, Marion. >> Objection. Spousal privilege. >> Can we get a recess? >> Mr. Reiger, you will refrain from speaking out of turn. >> to talk to my wife. >> After he told me that she wasn't leaving I knew what I had to do. Can't do this. I won't let you do this. >> That's it. Remove this man from the courtroom. My husband did not kill Natalie. I did. She's lying. She's trying to protect me. I must BE ALLOWED TO SPEAK WITH HER. I'LL SEE EVERYBODY IN chambers now. Did Did you plan to kill this girl, Mrs. Reiger? Once the affair took on a life of its own, once Carl proved to me that he was unable to relegate it to the insignificant diversions the others had been, once Natalie [music] indicated that she had no intention of abiding the ground rules that I had laid down, I felt [music] I had no choice. Marion, please. That you are weak comes as no [music] particular surprise to me, my darling. How can you leave me? I would like for you to arrange to have someone stay with Carl so that he doesn't hurt himself. >> [music] >> After that, I would like you to make whatever arrangements are necessary for me to [music] begin serving my sentence. >> [music]
