Im not passing ju ining judgme two crimes, two mysteries that puzzled police until they found a link to one woman in love. She spoke to her friends that morning. She had a list. Make sure nelson gets here by 8 30 so we can have dinner. She was about to face the man she betrayed. You have previously stated that shes crazy. Crazy, angry. And the man she once loved in court. On the day of her murder, you had who was lying, and who was telling the truth. Im lester holt, and this is dateline. Tonight, obsession. Heres chris hansen. How could it happen here. A place so rich in privilege and promise. This was home. This was safe. All that darkness and pain, all that rage, it was coming for her. This would have happened sooner or later, no matter what. It was a crime triggered by a lovers obsession. And it drew the police down a rabbit hole of deadends and a big strange twist. Were you surprised. More surprised how it ended up than how it started out. I couldnt put any pieces together. Nothing made sense to me. Nothing made sense. What kind of a person is capable of doing that . You have to be a true psychopath. The story begins in stanford, connecticut, where anna lisa ra mundo lived a charmed life. She was athletic, a harvard grad who got her masters at columbia. By age 32 she was already a pharmaceutical executive and living large. Nice car, nice restaurant, and a waterfront condominium. Her apartment was gorgeous. And she had tons of plants. It was on the water, two floors, and it was just beautiful. Her friend and coworker christine dinerstein said everyone admired an lisa. Anna lisa would walk into the room and the room would light up. To some, she was almost bigger than life. Brilliant, lively, elegant. Theres anna. She had such a desire, and thirst for life. Hi, anna. Something her brother and sister couldnt ignore. Her love of life was contagious. Mom, dad, i love you. Like the time she taught her little sister bernadette into going skydiving. It was all her idea to go skydiving. She made me do that. I never wanted to go skydiving. And she had a boyfriend. She adored him. She was in love with him. They met at work. His name was nelson sesler. What kind of a guy was he . The exact opposite of her. She was very outgoing, and he was very quiet and subdued. They kept their relationship kind of quiet around the office. They worked at the pharmaceutical firm purdue pharma, along with christine. She says anna lisa was ready to get married. Nelson, not so much. Anna lisa would tell me that, you know, he was back and forth. She didnt feel that he was ready to commit. But their romance seemed to be picking up. In fact, nelson joined anna lisa and her big extended family at her sister bernadettes wedding in michigan. There he is watching anna lisa, the maid of honor. And he seemed like a good sport. Even joining the man in the garter toss. Do you think they were heading towards a serious relationship . It seemed it. At my wedding, actually, she was the one who caught the bouquet. So we kind of looked at her and said, oh, youll be next. About a month after the wedding, the couple went more public. They planned a night out in manhattan with work friends. This was our first time getting together as couples. Christine wasnt worried at first when anna lisa and nelson didnt show up on time. Anna lisa had been late before. 7 30 comes, we call. Anna, where are you . But we expect her to be late. 8 00 comes, were still calling. Were waiting for you. Give me a call back as soon as you get this. I must have called her phone 25 times, if not more that night, looking for anna lisa. So dinner went on without nelson and anna lisa. Driving home from the city that night, i said to the person i was with, we should stop by the condo to see her. For some reason we didnt. What christine and her friends could not have known was that someone else had gone to the condo earlier in the day. Hello. A guy attacked my neighbor. You think someone attacked your neighbor . A 911 call had sent police rushing to anna lisas home just after noon. Tom mcginty would lead the investigation with greg holt. What did you find . The door ajar. As you looked inside, you saw the female victim lying on her back, and seemed like a violent struggle. It was anna lisa. She had been beaten and stabbed repeatedly right in the middle of the day. There were plants overturned, dirt on the floor. Very bloody scene. Did it look like she had struggled . Very much so. Absolutely. She fought for her life. There was no sign of forced entry. The investigators figured anna lisa had opened the door to her killer. Was it someone she knew . And who was on the short list of potential suspects . You always start with a small circle and go out, and her small circle would have started with her boyfriend. Nelson sesler . Yes. Police didnt have to go looking for nelson sesler. He drove up to anna lisas complex about the time he and anna lisa were supposed to go to dinner. Investigators broke the news to him and then told him to stick around. He was asked to wait outside, and he was put in an area of the condo which is commonly referred to as the boat house. About 700 miles away, local police in bloomfield hills, michigan, were bringing the terrible news to anna lisas family. How did you learn that your sister had been killed . There was a loud knock on our front door. Shocked us out of bed. And i went downstairs, and there were police. Its hard to process that this has happened. I still kept thinking, no, they couldnt have gotten it right. Bernadette had to tell her parents. And i said, what happened to her . Was she in an accident . I told her to be careful, you know. I was just shocked and crying. I felt so bad, and so weak. And it was a shock, you know. Back in connecticut, Stanford Police were getting a surprisingly different vibe from anna lisas boyfriend, nelson sesler. Was he emotional . If he was, he didnt show it to us. Did he ask what happened to anna lisa . Never to us. No. Not at all. Never to us. In fact, went to sleep. He went to sleep . Went to sleep in the boat house. As seasoned detectives, what did that say to you . Raised a big flag with us. Big red flag with us. Yes. Makes you wonder, did nelson sesler know more than he was telling police about the murder of his girlfriend . And what would have been his motive for murder . No one could figure it out, especially his friends. How could he do this. Why would he do this. It didnt make sense. Neither did a strange game between a husband and wife, but it would provide a critical clue to solving anna lisas murder. When obsession continues.

Ok, did she seriously just say that . Geico. Just click away with our free mobile app. Anna lisa. Anna lis i lost my mentor. It didnt seem real. Theres not a Single Person in this world that would ever want to hurt anna lisa. Maybe, but someone killed her. And it didnt look random. No burglary gone wrong. She knew her killer. Who would possibly do this to your sister . We had no idea. How do you even comprehend that as a parent . You cant. You cant. What they really couldnt comprehend was that Anna Lisa Raymundo was anyones victim. She wasnt just physically strong, she was smart and cautious. Not an easy target. So hard to believe that only a month before she died, anna lisa and her boyfriend, nelson, were together at her sisters wedding. And everyone wondered, was he the one. Now he was at Stanford Police headquarters fielding questions about his girlfriends murder. Everything we tried to get from him, we had to pull from him. Nelson said he slept at anna lisas the previous night, as he often did, and last saw her alive that morning when he left for work. He said he spent the rest of the day at the office. One of our questions to him, over several interviews, if he had any girlfriends, anybody else he was seeing at the time he was seeing anna lisa. He continually said no all the time. Do you think he was holding back on you during that first interview . No question. No question. When Nelson Sessler leaves that interview, was he still a suspect . Absolutely. But friends were baffled, nelson, a murder suspect . How could he do this. Why would he do this. It didnt make sense. Police took a hard long look into sesslers whereabouts the day of the murder. We were able to obtain all his records from work, video of him at work. He left the morning in those clothes, came home in those clothes. No marks, no blood on him. Basically the next morning we could have him at work all day. So he had an ironclad alibi. Absolutely. So Nelson Sessler wasnt the killer. But the police still wondered about him. I didnt like him as the perpetrator in this, but i liked him for being right dead set in the center of this. By now, other suspects were surfacing, and tips were coming in about one in particular. A sketchy guy who had been hanging around the docks. He had been seen by one of the residents in the condominium complex who also had a boat moored out there. His name was gary riley, and he wasnt just seen the day of the murder, he was heard telling people things. He had talked to many people, giving them information about the crime, which kept coming back to us. Did you talk to gary riley . Several times. And what did he tell you . He would deny what he told other people. Police dismissed riley as a big talker, and a stranger to anna lisa, not a likely suspect. And remember the 911 caller . Clearly she knew something. Yes, hello. I think a guy is attacking my neighbor. The call had come from a pay phone just down the street from anna lisas house. You think someone attacked your neighbor . Yes. I heard yelling. I heard yelling. The woman calling didnt give her name, and abruptly hung up. Hello . Police check with anna lisas neighbors. No one could identify the caller. Another dead end. Was there a time when you thought this case may never be solved . Oh, definitely. I felt like the police had no idea, no direction. It was just a mystery. So youve got suspicions about Nelson Sessler. Youve got a 911 call. Youve got a lot of blood and evidence from the crime scene. But no primary suspect. No. How long did this case stay that way . Id say about five months. A long five months. And then on march 23rd, 2003, just across the connecticut state line, here in westchester county, new york, another stabbing would change the course of the anna lisa investigation. A woman brought her husband here to the westchester medical center. He had been stabbed in the chest. And this couples story was so flatout weird, veteran Police Detectives are still talking about it. She originally tells me that, you know, he had come home from work and he was injured. Westchester county detective allison, said that while the husband paul was being taken to the e. R. , she spoke with his wife, a woman named sheila davalu. I sat down with her. She was polite, cooperative. He came and said he laid on the floor. He was bleeding. And i got nauseous. I couldnt look at it. But this case was about to take a hairpin turn, because the gravely injured husband was conscious and telling a very different story. He said he was injured while he and his wife were playing some sort of game at home. Tell me about it. We were playing a game. Well, clearly something went wrong, and police were about to learn that this game, this injured man and his wife would have a curious connection to the life and death of Anna Lisa Raymundo. Coming up, exactly what kind of game was this couple playing . Now, im not passing judgment, but when a game involves a blindfold and handcuffs you want to think, its got to be it had been five months since the stabbing death of Anna Lisa Raymundo in stanford, connecticut, and now i was in shock. I think i dropped the knife. I was holding it down so it wouldnt hurt him anymore. Police in westchester county, new york, were engaged in a bizarre conversation with a woman whose husband had been stabbed. The wife was fuzzy about the details. But the husband told investigators he had been stabbed while the couple was playing some sort of game in their home. You can blindfold each other, tie each other up and you have to guess whats touching the body. Paul christos will never forget. What did this game involved . It was described as a guessing game where you would be blindfolded and you would have to guess what the items are. Im not passing judgment here. Right. But when a game involves a blindfold and handcuffs you want to think, its got to be sexual, right. You would think. Yeah. Its a good point. I wouldnt be afraid to say it was sexual. The truth is, it wasnt. Kind of an odd diversion for two academics. The wife, Sheila Davalloo, was a research scientist, her husband, paul christos, was pursuing his doctorate in epidemiology. She said she just wants to play this game. It will take a couple hours. Shell be happy and ill go back to my work. Paul says sheila went first. She was handcuffed to a chair. Paul put a few items against her face, a camera, a shampoo bottle. She tried to guess what they were. And then it was pauls turn. Blindfolded, handcuffed, the whole drill. How long did it take until this game took a very bizarre, painful, dangerous turn . I would say after five or six items, i felt a large, or heavy thrust on my chest. Almost felt like a dumbbell dropped on my chest. Did she say anything to you . I think after three seconds passed, i felt another large thrust on the chest. And then she said, oh, my god, youre bleeding. I think i hurt you. There wasnt a lot of blood. He said the pain wasnt severe. So he wasnt sure what happened. I saw one wound that didnt look deep or anything. I thought maybe she had a seizure and fell on me, or did something. But now i come back to reality, because shes helping me get out of the chair. Paul said sheila seemed to panic when he started to bleed. So he took charge, telling her to call an ambulance. I said, all right, call 911. She gets on her phone, i hear her pacing around the room. My husband has been hurt, please hurry. In her conversation with detectives, sheila did seem distraught at times. Tell me. What happened . You had a great day. Sheila i dont want to talk about it. It took a while, but sheila finally admitted to the game. She did cut paul, but said it was an accident. How do you accidently cut someone. We were playing a game. It got out of hand. It was an accident. I kept saying, i just dont understand. You have to explain it to me. I dont believe you. Sheila insisted she wanted to save pauls life. But after that 911 call, no ambulance came. And thats when she drove him to the hospital. I would not have hurt him. If i wanted to hurt him, i would never have come to the hospital. But it was at the hospital right there in the parking lot that the case of the husband, the wife and the game took an unexpected turn. Police spotted sheilas cell phone lying on the ground. You know, the one she used to call 911. Im thinking im going to find 911 on the phone, that she had called for help for her husband. We didnt find that call on the cell phone. But we did notice after he was injured that she did call a gentleman by the name of nelson. In fact, detective carpenterier found she didnt call 911. The only call she made was to Anna Lisa Raymundos boyfriend. Why would Sheila Davalloo, who had just stabbed her husband, call Nelson Sessler . Whats the link between those two . And what did it have to do with the murder of anna lisa . Two stabbings in a short period of time, and theyre both connected to nelson . Something does not make sense. When obsession continues. S.

A woman named Sheila Davalloo stabs her husband during a weird guessing game, and then of all people, she calls Nelson Sessler, the boyfriend of a woman who had been stabbed to death just a few months before. Coworker and friend christine got the news right away. I get to work. And i go sit down at my desk. And someone comes up to me and tells me, did you hear what Sheila Davalloo did . As it turns out, Sheila Davalloo also worked at purdue pharma, where christine, Nelson Sessler and anna lisa worked. Sheila was known as a competent biochemist and researcher, friendly, social, very smart. She was very successful. Not a lot of promotions in the company. The story about sheila and that night swept through the office. Ive never heard of anyone getting stabbed in my life, and here it is, two stabbings in a short period of time . And theyre both connected to nelson . Something does not make sense. Thats pretty much what detective carpentier was thinking. They asked Nelson Sessler to come back for another interview. Stanford investigator tom mcginty was there as well, as sessler admitted that he and Sheila Davalloo were friendly. He was talking about his relationship with sheila, how they were such good friends and they used to go skiing. And she had purchased two dogs, and he would go over to the house and walk them for her. I said to him, nobodys driving to westchester and not getting laid. He finally admitted he was having a sexual relationship with sheila. Nelson was now admitting there had been another woman in his life. He had dated sheila and anna lisa at the same time. But said he broke up with sheila as things got serious with anna lisa. That was the two months before the murder. And after the murder, he and sheila hooked up again. How did you react when sessler finally came clean to you and said, yes, i was having a sexual relationship with Sheila Davalloo . It was very upsetting. Hes been working this case, anna lisas homicide day and night. So the fact that nelson was keeping information from him was definitely upsetting to investigator mcginty. And there were more surprises. Nelson sessler said he had no idea sheila had a husband. And the husband didnt know anything about nelson. Until detective carpentier told him. She also told paul about anna lisa. And thats when it clicked. That name, anna lisa. She was telling me the story at work about three people, melissa, jack and anna lisa. It was an office love triangle. Sheila said it involved her very, very good friend melissa. Who was hooked on a guy who had a girlfriend named anna lisa. And sheila talked about it a lot. She seemed to want to tell everybody about it. She told me, she told friends of ours. Sheilas friend tammy mae heard about the love triangle and she heard about it all the time. Sheila would talk about her friend almost more than she talked about her spouse. Almost to the point she was obsessed with it. She would even talk about their sex life quite a bit. When sheilas affair with Nelson Sessler was uncovered, the fiction dissolved. Jack turned out to be in reality Nelson Sessler. All of sheilas stories were really about herself, and her own apparent obsession with Nelson Sessler. Maybe nelson thought it was a casual fling, but sheila sure didnt. And it was only days after anna lisas murder that sheila moved in on nelson again. According to Nelson Sessler, sheila began to bring him care packages a couple weeks after anna lisa had died. It became very obsessive. When i think nelson learned the extent of the obsession, it became alarming. How would you best describe Sheila Davalloo . Manipulative. Highly intelligent. And very good liar. Suddenly, and for the first time, Police Investigating the murder of Anna Lisa Raymundo had a suspect. They wondered if nelson broke up with sheila with anna lisa, how far would sheila go to get him back. Coming up, she was clearly an obsessed woman. But is anybody this coldhearted . She had her nails done that morning. She spoke to her friends that morning. She had a list, get my nails done, have lunch and kill my husband. And. Done. Did you just turn your ringer off so no one would interrupt us . Oh no, i. Just used my geico app to get a tow truck. Its gonna be 30 minutes.

Ooh woman with a motive, after five months of deadends the investigation into the murder of Anna Lisa Raymundo was heating up. Police were learning that Sheila Davalloo had been obsessed with anna lisas boyfriend Nelson Sessler. She was talking about him all the time. And she wasnt just talking, stalking, spying on nelson and anna lisa. Even her husband paul knew about it, sort of. It was like, im helping my friends with a cheating boyfriend. That sounds fine, go ahead, do it. I even had the night vision binoculars i had from high school. Take these, you can see in the dark pretty well. If sheila was spying on anna lisa by night, the next question was, where was she on the day of the murder. Police contacted purdue pharma. Sheila had checked out of the office that very morning. Next, they got a search warrant for sheilas apartment. We recovered packaging and receipts for two stun guns. Two stun guns . She had a lock pick set. And she had night vision goggles. And recording devices. Police now had a theory. Sheila davalloo was so obsessed with Nelson Sessler that she stau stalked his girlfriend and went to her home to kill her. This was not a spontaneous crime. This took a tremendous amount of planning. Five years after anna lisas death, Sheila Davalloo was arrested and charged with her murder. Its like one of these lifetime movies where you hear about this kind of stuff. Its so hard to believe it. And sheila would say its hard to believe, because she was being railroaded. The evidence was flimsy. There were other suspects. And the case was purely circumstantial. There you go. Yes, we are, your honor. When she finally went on trial early last year, Sheila Davalloo was fully prepared to take charge. She decided to represent herself. Shes so arrogant, she thinks she can do better than her own lawyer. But she did sound the part. Good afternoon, ladies and gentlemen of the jury. Objection, your honor, hearsay. She was polite, professional. No further questions, your honor. And so steady. This educated, friendly, mildmannered woman was the same one who viciously stabbed Anna Lisa Raymundo to death . Exactly, according to the prosecutor and police. She planned the killing, she carried it out, she covered it up. Nelson sessler, a onetime suspect, was now introduced to the jury as just another victim of sheilas lies and manipulation. At any time prior to march 23 of 2002003, did she ever tell y she was married . No. She never did. And a lowkeyed demeanor that police had once found so suspicious, now it seemed thats just how he is. Hes very laid back. Hes too laid back. People might miss interpret that for not being emotional at all, or not caring. But i think he does care, and he did care. He just didnt notice, according to the prosecution, that Sheila Davalloos feelings were so intense. He even seemed clueless in the summer before anna lisa was killed, sheila suddenly showed up on his flight for las vegas. I looked up to see Sheila Davalloo walk up to me. At the airport . At the airport. There she was. And she was on the same flight as me, coming back where was she sitting on this flight . She sat next to me. Was this a complete surprise to you . A complete surprise to me. But sheilas friend, tammy mae, knew this wasnt a coincidence. Sheila told stories about hacking into sesslers voicemails, and she knew exactly where he was going to be. She pretended it was destiny or fate. She was so manipulative, the prosecutor suggested that when she killed anna lisa, she used nelsons grief to seduce him again. Sheila was one of the few people that i knew in stanford that actually, you know, was willing to talk about it. Most people sort of shunned me. You know, i really didnt have a whole lot of friends here to talk about it. But the prosecutor had to show the jury that not only was Sheila Davalloo obsessed with Nelson Sessler, she was willing to kill someone to have him to herself. State calls to the stand paul christos. Thats why the testimony of paul christos was so important. Its surreal. I look back and can almost look at it in the third person. The prosecutor argued when sheila rekindled her affair with nelson, her husband paul was now in the way. She staged the game. She stabbed him and then agreed to drive him to the hospital, albeit slowly, until she hoped he would bleed to death on the way. Paul told the jury how he begged her to hurry. Lets go, its taking too long, i cant believe how long this is taking. When they finally arrived and he was still alive, the prosecutor argued her deadly intention became clear. The time was up for paul. She came in through the drivers side rear door. At that moment she lunged at me. Lunged . Yes. And stabbed me in the chest. Now youre really bleeding. Yes. This one had a lot of blood. This time she nicked his heart. What are you doing, oh, my god, youre trying to kill me. And remember that call she made to nelson after she first stabbed paul . She was inviting nelson to dinner. For that very night. Paul, who is now divorced from sheila, finds the whole thing unbelievable. She did her nails that morning. She spoke to her friends that morning. Shes doing her normal things. And then she figures shell get rid of her husband. She had a list, get nails done, talk to friends, kill my husband. And make sure nelson gets here by 8 30 so we can have dinner. So now if the jury was wondering if Sheila Davalloo would actually do this, the prosecutions answer was yes. Because she did this. And where there was motive, the prosecutor argued, there was opportunity. The jury heard how sheila checked out of her office the morning of anna lisas murder. She had no alibi. And remember that mysterious 911 call that came in minutes after the murder . A guy is attacking my neighbor. Police believe the caller was Sheila Davalloo herself. The prosecutor said Voice Recognition software showed it was indeed the defendant. That call was intended obviously as a matter of common sense, to throw the police off her trail. The prosecution had a suspicion 911 call, no alibi, and a killer motive. But was that enough to put Sheila Davalloo away. Coming up, Sheila Davalloo was about to do something perhaps never before seen in a courtroom. Crossexamine the exhusband she tried to kill. And the man she allegedly killed the case against Sheila Davalloo was loaded with motive. Love, rage, obsession. But the prosecutor needed evidence that put her at the scene of the crime. And thats where a cut on sheilas hand came in. Sheilas friend, tamy mae, testified that she noticed the ugly gash just a few weeks after anna lisas murder. I was like, oh, my goodness, what did you do . She said she cut it on a can of dog food. But what if she cut herself during the murder and left some dna behind. Police checked sheilas dna against some blood found at the crime scene. Do you remember your exact words . His exact words were, weve got her. Sheila davalloos dna was found in a drop of blood on a sink handle in anna lisas bathroom. Theres only one explanation for that, and thats that she did this crime. It is consistent with guilt and only guilt. But it was just one tiny drop. Would that be enough to convince a jury. Im
