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.

[ 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 thr
