Own home, held a virtual prisoner, your children in danger from a man with a blue print for murder. I was terrified. Tonight she will facedown evil and come forward with a new revelation that make your jaw drop. Ill lester holt, and this is dateline. Heres Andrea Canning with the killing in cobb county. A new attraction can be so exhilarating, but not always. Sometimes an attraction turns into a dangerous obsession. Lotty spencer knows all about it. Lottie said she had a stalker, a teenage who are got into her house, into her car and worst of all into her head. I wouldnt go out to the mailbox without a gun. I was terrified. He had total control over your, it sounds like. Lottie felt powerless to do anything about it. I knew he was watching. Here it comes again. Life used to be much simpleler for lottie. This is an upscale neighborhood and kristine and i were always outside. Their upstairs neighbors were carmen and nick. She was a gorous strawberry blond, feisty, very outgoing young woman who loved her son more than anything else in the world. They were two peas in a pod. It was a monday afternoon, the week before halloween. The first thing they did was go downstairs to see if they could find nicks mom, her car was there, she should be there. While christina stayed by the door, nick went inside, someone was there, but not his mom. Nick turned the corner and he saw something move across the bedroom down the long hallway. It was a dark figure wearing gloves and a mask. The stranger suddenly stabbed nick and left him for dead. As hes laying there on the floor, he actually sees his perpetrator run from the house. Christina began really freaking out. She was terrified. Christina ran upstairs to her apartment to get help. Her babysitter was there and her boyfriend scott. I grabbed her shoulders and i stopped her and i said dont touch anything. The glass door was smeared with blood. Somebody said oh, my god, theres nick. I said get out of here, go down the street. She said what are you going to do . I said im going to get that boy out of there. Im not leaving without that boy. Scott grabbed an ax for protection and then dropped it when he realized how desperately nick needed help. I slapped him a few times and nothing happened. So i started screaming at him and started smacking him harder and telling him he wasnt going to die today a. And all of a sudden, he sat up. He squeezed nick tightly against his chest. Trying to stop the bleeding. He said call 911, call 911. Lottie was at work when she got a frantic call from her daughter. She was hysterical. She was screaming that nick was hurt. I drove home as fast as i could. Lottie didnt see carmen either, but when Police Officers arrived at the scene, they made a grizzly discovery. The Flight Attendant and devoted mother was dead. She had been strangled. She was just 34 years old. Youre shattered and youre so thankful that your daughters alive. But you feel so bad what happened to nick and carmen. Reporter carmens sister and brotherinlaw jim barely had time to process the news about carmen before hearing that nick was fighting for his life. We went straight to the hospital. You must have been thinking how could someone stab your nephew 18 times. Thats a monster . Exactly. Ill never forget walking in that hospital, but yeah, and then you have to come to grips with reality. And it was a grim reality. After emergency surgery, nick was in critical condition. He looked so little, so fragile in his hospital bed. You never think you can be touched like Something Like this when youve got the perfect family. He had been stabbed 18 times and had lost a dangerous amount of blood. But he survived. Nick was going to make it. It was nothing less than a miracle. There was no easy way to tell him about his mom. But he had to know. And even 18 years later, nick remembers it like it was yesterday. My dad and my aunt told me that my mom didnt make it and i didnt really understand it then. I still developmeont really un it. It was such a senseless act, nick and his family could only grieve and wonder why. But back at the apartment, now a crime scene, a chill ran through lottie, she told police she could explain exactly what happened. I told them that i had somebody that had been stalking me. And it was my belief that he was the one behind what happened to nicholas and carmen. Who was this man in the mask who would kill the young mother and try to kill her son . Hes pure evil, hes a monster. When we come back, a haunting story of hunter and hunted. He has always told me that he can get away with a perfect murder. His plan was in the making. To clean this mess. E then ill use a bunch of them. Then how is that a bargain . [ sighs ] no, thats too many its not gonna fit whoa cascade kitchen and mth counselor. Heres a solution.

[ male announcer ] at t makes you the hero this Holiday Season with iphone5s for zero down with at t next. It is a haunting memory, impossible to forget. It definitely changed my life, of course, completely. So i remember pretty well. Now 23, nick smith was only five years old when a masked man stabbed him 18 times and killed his mother carmen. While recovering in the hospital, nick was told his mother was gone. Do you remember your mom . Not as well as i wish i did. Most of my memories are just stories i have been told from other people. Carmens sister and her his july helped raise nick. He was in swimming, softball, track. And she was in homecoming court, she was a cheerleader. I remember her liveliness. She was very vivacious, very beautiful and fun. She had nick very early in life and did a great job of working and providing for nick at the same time. Do you feel robbed that you didnt get to experience all the things a mother and son get to experience together . Yes, everybody said that she was a very happy person. A happy life that ended up in violence. Did you know immediately who had done this . Uhhuh. Who had committed this . I knew. Lottie was certain it was the work of a teenager name waseen. She told detectives her story. Things had started so innocently. Dont they auld . We met by being teammates on the same team. Kind of a den mother to the other much younger players. Especially waseen, a tech student 12 years her junior. He didnt have anybody he could share his thoughts and feelings with. You felt like a big sister to him . Baker was a bit of a loaner, he latched on to lottilottie, cg her and work and at home. I said youre taking up too much of my time and then he started crying. I knew it was a problem. Her phone started ringing off the hook, up to 100 times a day. Why didnt you just stop talking to this person . I should have. I felt really sorry for him. He also said to you that you were a good person. Or a very foolish person. He started flipping out, yelling on the top of his lungs that hes going to get me and slit my daughters throat in front of me. I would come home from work and there would be a pair of my underwear on my doorknob and a few days later a bra. What message was he sending with that . Look at me, im getting into your place and theres nothing that you can do to stop me. Another time i came home early and i went into my bedroom and there was waseen baker naked, wear inggarter hose and a garte belt and looking into my mirror. Once again baker threatened her and her daughter, this time while brandishing a knife. He has always told me he can get away with the perfect murder. Finally lottie decided to let the Justice System take over. Baker was arrested in august, but released on bond. A judge ordered him to stay away, he didnt and he was arrested. This time he was sent to a Psychiatric Hospital for evaluation. Hes got some severe issues with obsession. I dont think he has the ability to feel compassion for other people. Hes clearly a brilliant individual, hes also a brilliantly airy individual. While baker was hospitalized, lottie packed up and moved to the house in cobb county where carmen and nick lived downstairs. In october on friday the 13th, waseen baker was released from the hospital. Less than two weeks later, carmen smith was dead. Now Lottie Spencer was overwhelmed with guilt and anger. Hes a monster. And thats what lottie told police, he said hshe said he mu one lottie thought she knew the answer, a phone call that baker made to carmens phone a few days before the murder. It was friday the 20th. And the calls started coming in, the phone got put off the hook and then i could her hear phone ringing. Carmen answered and then hung up abruptly. What was said . Nobody knows. But carmen told her sister and brotherinlaw that he was after lottie baker. We had talked about her packing some stuff and coming to stay with us for a while. Lottie says seeing carmens reaction to bakers call was heart breaking and she did what she could to help her neighbor feel safe. From the entryway, from the sliding glass door, we just barricaded the door with some wood. She was so scared. She was shaking and she was so scared. Just three days later, that glass door was open and smeared with blood. And waseem baker was the lead suspect in a horrible crime. Coming up, evidence at the scene of the crime. There was a broken knife blade and hair and fiber was recovered a off of smiths body. Will it be enough to catch the killer . Hes getting away with murder. Hes getting away with exactly what he told me he would. When dateline continues. N. He needs a honey, i love you even more than the day we got married necklace.

Only at a sleep number store. Sleep number. Comfort individualized. Just three days before she was killed, carmen smith told family and friends she had been called by waseen baker. It was the strongest allegation yet connecting the victim to the suspect. Investigators tipped off on that call by lottie. Now zeroed in on waseem baker. In his room, we found a piece of paper with the address where this crime occurred. We found a torn up letter that was his words to Lottie Spencer. Baker er torn up letter to lottie was hateful. He specifically talks about having plans and backup plans to exact revenge on lottie and the worst part about the letter is he gets to the end and says im going to let you live. Im going to get revenge on you, but im go to let you live. It looked like a blue print to murder. Now they tried to link baker to the crime scene. Some of the important evidence that we start with the dna evidence found on carmens body. Carmen had small puncture wounds on her back, and terrible bruising suggesting a ferocious struggle. He had been tortured and murdered but she had been undressed at some point and redressed. At carmens bed size, the hammer she had wanted for peace of mind. Never touched as she fought for her life. Not far away was the suspected murder weapon, a piece of rope. Crime scene technicians dusted for fingerprints and cleshlolle blood samples. The evidence was sent to a state crime lab. The evidence came thats when we knew that it may always be a circumstantial case. And the circumstantial part of the case was just too weak to make an arrest. Prosecutors still believed baker was the only viable suspect in carmen smiths murder and the stabbing of her son nick, but they didnt have the every to prove it. The investigation stalled. So it did seem that baker walked away from the murder . Away from the murder, but not from accountability. The police thought they had a viable way of charging him with stalking. Baker was arrested and charged with stalking Lottie Spencer. There are friends of his and friends of hers that were witnessed to the stalking behavior of baker. Baker was convicted in september of 1996 and sentenced to ten years in prison. It was the close to the worst chapter of Lottie Spencers life. But it wasnt a happy ending. Did you feel like you had some peace in your life again when he was behind bars . No, because he was getting away with murder. He was getting away with exactly what he told me he would. He needed to pay for what he did to carmen. After the trial, lottie decided to leave georgia to try to start over. Nick smith went back to the same school and the protection embrace of his family. I kind of just went back into the normal routine, i think that was the best way that i could have dealt with it. And i think my family did a pretty good job of trying to keep my life as normal as possible. During the next ten years, nicks life finally did return to normal. But in 1996, baker was released and relocated nearby. Police decided to provide security to keep nick safe. They would have the cops sit outside of our house at night and we had cameras installed in my house on the outside, just as a precaution. Lottie says he was also looking over her shoulder. Telling me about the day that he got out, that he was a free man again . Not a good time. Were you waiting every day for the phone to ring or that bang on the door . Yep. I was starting to unravel again. Coming up, the fear begins all over and so does the push for justice. You had your smoking gun . Absolutely. Its another trial for what waseem baker.

He was still terrorizing you in some ways . Yes. Hes like your worst nightmare. After his release, daker got a job and moved to southern atlanta. Here he is sky diving and loving it. Dakers freedom galled investigator john dawes. To dawes, daker was the one that got away. Does a case like but for years dawes couldnt do anything about it. And then just by chance, he was cement sent to a dna Training Seminar in 2008. Back in the mid 90s, very little at all could be done with the hair, except to say the color of the hair. Now when theres any tissue from the root on the hair whatsoever. It takes a minute amount of tissue to come up with a dna profile. Carmen was a strawberry belonged and he remembered the short, dark hairs recovered from her body, not hers, under layers of bedding. I felt it was invaluable evidence if there was enough tissue on that hair underneath her sweater. It was almost 15 years after carmen smiths murder when the call came in. There was a match. They have identified waseem dakers hair, him and only him, to the exclusion of all others, on the dead body of carmen smith at the time that she was found. You had your smoking gun . I got a call from detective dawes. I was very happy, but it was really hard for me to have to go back and tell the story of the things that he did. Lottie dreaded the thought of testifying in open court, in front of daker, but she knew there would be no avoiding it. Daker was arrested and charged with murdering carmen smith and stabbing her son nick. His trial started in september of last year. All rise. Prosecutor jesse evans was there for the state. This case ladies and gentlemen is about obsession. Daker was a violent stalker and his obsession with one woman led to the murder of another. You cant get into the mind of a psychopath and see why those critical hairs. The cold case with Dna Technology proved positive that daker was the murder. Waseem daker was waseem daker. I want to point out three principles of law. Before he had taken over his case, daker had been represented by a father and son team. They had no case without those hairs. Thats why they didnt go forward. Their advice to daker, focus on those hairs and dont obsess about lottie. This case had to be defended by attacking the science of the states case. But daker couldnt seem to let go. His focus from the start was his relationship with the states star witness. It was a roman, daker said, intimate in any way. Lottie insisted that was not true. Some of the things he said just had to be really beyond frustrating that you two had a sexual relationship . There was no relationship. So theres nothing, you know, more that i can say about that. Did he ever try and do anything like kiss you since hes so in love with you . Never once tried to kiss me or anything. When daker finally turned to those hairs, he called on a prominent dna expert who chan s challenged the states key evidence. The problem he says, is none of the hairs recovered from the crime scene had any roots. There were hairs taken from the body and they were all clearly indicated on the reports as having no roots. Thats something you can do with the naked eye and of course the experts at the time used a microscope . Are you sure that the original hair had no roots . Somehow it arrives rat this laboratory and theres hair with roolts. Daker once again connected the evidence to Lottie Spencer. A liar, he said, who had ruined his life in the most treacherous way. She derailed the Murder Investigation by making all those false allegations. For lottie, all of the fear and hurt from her darkest days came rushing back every time daker mentioned her name. He was enjoying it. Like he had control again. A and that made he feel like, really weak. Jesse evans asked the jurors not to focus on lottie and to think about another woman when they started their deliberations. Car momecarmens body was la rest, but it was not in peace. We were really holding our whole case together with two hairs. Two hairs from the victims body. If theres a plausible explanation for how those hairs come back with a dwrna result. It took the jury just 3 1 2 hours to reach a verdict. We the jury find the defendant waseem daker guilty of count one, malice murder. Guilty of the murder of 30yearold carmen smith. You go all these years thinking that he got away with it. And he didnt. At dakers sentencing, the state called just one witness, nick smith, who was determined to face his attacker one last time. I was not going to let him defeat me, no way. Waseem took my mothers life and stabbed me, my life was put on hold. Nick struggled to hold back tears. You wonder will someone other than me control my life and enter my thoughts. Hes finally caught and im finally free. I love you, mom. I never wanted to use what happened as any sort of crutch or let it get any way. I did the best i could. If she was still here, i think she would be proud. The judge decided dakers sentence, life was 47 years. Its typical of the coward that you would act the way youre acting. And thats what you are, a coward. Case closed. Justice for carmen and nick smith and the victory lottie had wofb wanted so badly. But the story was far from over. Something happened at the end of the trial that would come to haunt lottie, something that would lead her to realize that there was still unfinished an unbelievable business in her saga with waseem daker. The final chapter, not even close. A stunning confession is about to turn this case around. I couldnt let it go, i have a conscious, i have to live with me. When dateline continues. Oh hold on now.

It looked like he was out of Lottie Spencers life, finally and forever. It was very emotional. But just so good. So very good. Do you feel free . Finally free . I feel like a lot of weight has been lifted and im going to close this chapter and just go on with my life in a positive way. That was lottie last year, she told us she had closed that chapter, but it turns out she didnt, not by a long shot. In fact in the past year, she has turned this story completely upside down with astonishing revelations. We sat down with her again to hear her new version of things. So did not expect to be sitting here talking to you again. No. Major turn of events. Yes, there has been. It all began with a bombshell. Mr. Daker and i had a consensual sexual relationship. Yes, lottie now says she had an ongoing sexual relationship with what seen daker, that he wasnt really her stalker, he was her lover. It was something she had flat out denied for 17 years. If what youre saying is true, you lied to the district attorney, you lied in open court to the jury. You lied to me . Uhhuh. There are no words to describe just how very remorseful i am. What i did was wrong. I am taking 100 , full responsibility for what i have done. The damage i have caused this man. And his family is theres nothing i can do to take it back. Nothing. Lottie now says she lied under oath about the sex and about many of the stalking charges she had made against dak daker. Did waseem threaten you . Your life . No. Did he threaten anyones life around you . No. Were you in love with mr. Taker . No, i never was in love with mr. Daker. And youre not today . No. Until recently, she genuinely believed he was a murder. I was terrified of him. That was no lie. Those emotions were real. I had the nightmares, i lived in that fear. She says that fear drove her to lie to put daker behind bars, but the euphoria she felt after the verdict started to sour. She couldnt stop thinking about something prosecutor jesse evans today during the trial. He said that carmens lifeless body was wrapped up in five layers of bedding and i was shocked and i started to get pretty scared at that moment, because i had given carmen two blankets just before her death. They were blankets she now said that mr. Daker and her slept in together. Mr. Daker used those blankets on a number of occasions. He was welcome in my home and he spent the night and clearly i knew his dna could have been on those blankets. Remember, carmen had been found under several layers of bedding. If someone of lotties blankets was among them, i would could explain how dakers hair got on carmens body. This isnt a maybe, this is a woman whos risking perjury charges whos turning against her own selfinterest. This is a woman who can explain this evidence. You have to take this seriously. The paid Expert Witness for daker is now working on the case for free in his role as director of the idaho innocence project. He believes lotties story is a game changer. Now theres a logical explanation of how the hairs got there. This is one of those places where you just have to shake the system and say, wait a minute, this is so obvious i. I have a conscious, i have to live with me. So lottie decided to come forward. She filed affidavits with the court and over the summer, the judge granted a hearing for a new trial. But jesse evans wushts buying lotties new story. Thats because when he was preparing for the trial, he believed he found that storys rail source. Theres something thats going on behind the scenes that we werent aware of. Coming up, another revelation, inside a prison cell, 4,000 pages of secrets. Do you think waseem daker is manipulating lottie from prison . And coming up next friday on dateline, it started with a secret. Im just like, say what . Like my mom did what . A mom and new wife with an undercover life. She was really working for the cia . Thats my understanding, yes. A mysterious job handling classi classified, documents, but the real intrigue started when she went missing. I didnt want to believe that this was actually a reality. Where was she . Was this some kind of International Spy game or something closer to home . Everybodys out there crying. Everyones in tears. I couldnt give up, it was my sister. The deadly case of a cia mom.

Our nations future depends upon it. The more you know. For almost two decades, heres how Lottie Spencer talked about waseem daker. Waseem daker is evil. Hes pure evil, hes a monster. But now she calls him a victim. You know what . I messed up really bad. Despicable. Lotties reversal was astonishing. In the years since carmen smiths murder, she had built a new life, shes a single parent again, raising an 8yearold boy, living in a new home. By recanting her testimony, shes putting all that at risk. How worried are you that you could go to jail for perjury . I know im facing prison time and there will be a real penalty for what i have done. And i dont want to be ripped away from my little boy. I have earning to lose. A year after dakers conviction, a motion for a new trial. Daker called the dna expert to the stand. The man sleeps in the blanket, could his hair transfer to the blanket . Yes. And if a man has sex in the blanket, can his hair transfer to the blanket . Yes. Dakers chances really hinged on lottie. Next witness. Loretta spencer. Just prior to carmen smiths murder, i gave her two blankets. Blankets that i knew you used in my roswell parent. She acknowledged having a sexual relationship with daker and lotties old list of dakers abuses started to topple like dominos. Did the defendant ever threaten you with a handgun . No. Did i ever threaten to kill you or harm you . Never. Did i ever steal your bras, panties and hang them on your doorknob . There are people who are going to say that you are lying now. Prosecutor jesse evans portrayed lottie as a troubled, unreliable woman. Did you admit to us that you had some mental issues you were dealing with. I said i was suffering anxiety and dregs. From dakers prison cell. 4,000 pages of correspondence between the convicted murder and the woman who testified against him. I sent him bible verses, encouraging karz, i sent him a lot of case files. It turns out lottie has been helping with dakers appeal. Hes been giving her research assignments. She looks up cases, prints up documents, mails them to prison and waits for his next request. Theres no doubt by sending those letters to him, a convicted murder, a sociopath, shes opened the door, shes allowed him an opportunity to get back into her life. And we already know he has a history of manipulating her. Is he manipulating you right now to get what he wants . This is a repentan woman. He never said a word about giving my blankets to carmen. It wasnt until after she started secretly communicating with the defendant that she then made this broad assertion that, well, i had given some blankets to carmen. The problem is i challenged her on it. Describe the blankets, tell me which ones they were. She couldnt remember. Theres no smoking gun or smoking blankets in this case. I dont think theres any blankets, i dont think theres any evidence of that. Lottie not only recanted her testimony from two trials but described the incredible lengths shes willing to go to set daker free. You applied for a second mortgage to help in waseems defense and you even took out a Life Insurance policy naming waseem as the beneficiary . My daughter is the beneficiary, she would get a third, my son would get a third and daker would get a third. Yes, i would mortgage my house and i would hire him the best defense that he could possibly get. The fund rasing, the correspondent with daker, the legal research. Judge staley didnt buy her new story. She rejected dakers motion for a new trial. The right results were reached for the right reasons. I know we have done things the right way. The judge said she lacked correct and her new testimony appeared to have been concocted by the defendant. But lottie seems unbowed, ready to carry on her fight. Somebody needs to stand up and say, wait a minute, justice was not served in this case. And on that point, lotties not alone. J dakers shadow attorney agrees. What kind of more pivotal evidence could there possibly be . I believe there should be a new trial. How can you believe anything lotties said . I think when you have a man whos life is at take, you 12 people to hear her version now and let them decide if its true or not. They were an unlikely couple when they met. Even more unlikely partners today. But after all these years, lottie and waseem are still very much a part of each others lives. Are you ever going to give up on waseem . Are you in this until all appeals are exhausted . Yes, i played a role, of an innocent man being falsely convicted for crimes he did not do. I have got to make it right. I have no doubt that waseem daker is a coldblooded killer and justice has been served with his conviction. I hope that the Appeals Court agrees. If they dont agree this case is about carmen.
