She was all they had. Then came that awful day. These two beautiful 16yearold girls had come home from school and found their mother murdered. [ they were rocking back and forth, traumatized, disturbed. What had the girls seen that day . Could they provide a clue to help crack this case . We were told by the twins that nikki had a second boyfriend. Two boyfriends . Two boyfriends. Jealousy, passion. Revenge . She was fearful. She contacted the police. What secrets might the twins reveal . Its terrifying. Is it possible that this could happen . I was shaking. Oh, my god. Oh, my god. You couldnt even imagine. Im lester holt, and this is dateline. Tonight, watch for the double twist. Heres Keith Morrison with bad blood. Complicated life, a woman can get lucky, which is why youre looking at the sweet little town called conyers, georgia. Antique downtown, ringed by gated communities, good schools, a sheen of newness. It was really pure luck that brought Nikki Whitehead to this house, in this quiet, safe neighborhood. Just far enough away from atlanta, that capital of overheated ambition down the highway. He in conyers, she could give her beautiful twin daughters a better life than hers. But of course luck, fortune, fate can go either way. Sometimes in ways very hard to comprehend. Everything about this goes against nature. How could somebody do that . It was definitely the bloodiest crime scene ive ever been to. In the next few minutes, you will know exactly when it happened, where it happened, how it happened. But, of course, the real question is why it happened. And the answer t co that, as you complicated. But thats how Nikki Whiteheads life was. I loved everything about nikki. Yucca harris grew up with nikki, could see she was a wild child, pretty, fun, and irresistible. Nikki was, to me, a phenomenal, amazing person. Yes. And she was effervescent, said nikkis mother, lynda. Bigger than life. She was the kind of person that when she comes in a room, she just takes over the space, you know, with her personality, her laughter. But when nikki was 12, oh, boy, a handful. Lynda was a single mom with other kids at the time, so she agreed to let young nikki move in with della, nikkis grandmother. But della let the girl run wild. Grew up kind of fast. And then later, she became pregnant at the age of 18 or 19. So we moved kind of fast. Yeah. Yeah. Pregnant with identical twins whom she named jasmiya and tasmiya. Jas and tas. Born in 1993. The twins dad was around briefly, then gone. And their mother figure . Nikkis grandmother, della. Nikkis mother, lynda, didnt like it. I wanted nikki to get her own place, establish her own life, and my mom would discourage that. She would find ways to telhal her, no, youre better off here. Thats how it went for ye s. But nikki had learned how to style hair and was doing well at it. And eventually saw the possibility of independence. So she eventually wanted to kind of get out from dellas control, right . Definitely, she did. She wanted to as the girls t older, she definitely wanted and then one day in 2000, nikki was shopping at the mall. And robert head just happened to be in exactly the right spot. I was at the fountain one afternoon about 6 00. And there walks nikki coming into the mall. Your eye caught her . Yes, i couldnt let her go get away. That he was old enough to be her father didnt matter. Robert was in love. He persuaded her to go to dinner that very night. He took her dancing. He bought her nice things, treated her like a lady. She was my movie star. Thats what i called her, my movie star. His movie star with two sweet daughters he also soon loved as if they were his own. And thats how nikki came here to safe, secure conyers. This is roberts house. Here, they made a family. Unusual in some ways, as you will hear. But it was nice. Everything clicked just right. And she wanted her life to get even better. So while she kept her job as a hairstylist, she enrolled in atlantas Bauder College to study fashion design. Thats when i actually learned that nikki was a hairstylist. Rhonda anderson taught a couple of nikkis classes. She thought nikki had a sense of purpose, whether it was about her kids, her fashion, or other peoples hair. I came in to class early one day, as i normally do. She looked up at me and said, miss anderson whaerks , whats going on with your hair . I said what . Excuse me . Nikki asked me this question, do you have a hairstylist . Does she know you have your hair looking like that today . I said, yes and no. She said, miss anderson, im giving her one more chance. One more chance. If its not right, im taking over. Rhonda loved nikki, and nikki loved her girls. She put the twins in dance and music classes. At school they won awards. As almost angelic, sweet, and happy and engaged. And theres pictures of them, you know, one on each of nikkis arms. Catie beck is a reporter at nbc affiliate wxia in atlanta. Teachers describe t m that way, that they have a sweet demeanor in their classrooms and with their classmates. They were almost timid. And then as they reached their teens, they changed somehow. In the ways children often do, in the way nikki herself once did. And just like nikki, the twins were sent to live for a couple of years with the rather permissive family matriarch, della. Until 2010 when nikki welcomed tas and jas back, all together again in roberts house. A fresh start. And nikki turned up at school beaming. She was in a very good mood. She looked great. She had a new look with her hair. And she had braids in. As if the braids in her hair were kind of an announcement. Her girls were back. They were pretty much her pride and joy. Oh, you start thinking about her . Yeah. Its hard. Its really hard. It was january 13th, 2010. A sheriffs deputy happened to be in the neighborhood. The girls had just come home from school. The deputy saw a look of horror on their faces, heard their screams as they came pounding on his car. One of the twins ran up and literally beat on the side of this car and told him that they had come home from school and found their mother murdered. When we come back, exactly what had happened . They were going in and out of fits of tears and crying. About to reveal a clue. We were told by the twins that nikki had a second boyfriend. Two boyfriends . Two boyfriends. Two boyfriends.

As we get there, you have these two beautiful young 16yearold girls that discovered their mother murdered. Conyers Police Captain jackie dunn wanted to get jas and tas away from the house. Thats when he noticed they were hurting themselves. One of them was biting their arm. And we were like, hey, why are you biting your arm . She said, im so upset. I do that when im upset. This was the worst kind of case. Detectives need information fast. How do you get it from children who have just left their dead mother . [ crying ] they were going in and out of fits of tears and crying. I want grandma. Asking for their mom. I want my mama. Rocking back and forth, you know, contemplative, traumatized, disturbed. I want grandma. It will be okay. It will be okay. I can remember thinking, man, i hope there is a suitable Family Member to adopt these girls because they they really need sure. Somebody to reach out and be good parents for them. Word spread through the Late Afternoon gloom. A friend called yucca harris. She had asked me when was the last time i talked to nikki. I said, well, i talked to nikki saturday. She had told me that you may want to go over to her house because she said the helicopters were there. And the news reporters. Tell me when you heard that, what did you think . I dont know. It was like tunnel vision. I was just in slow motion. Yucca called nikkis mother, lynda, told her something bad was going on over at nikkis. I was so nervous, i didnt know what to do. I was like oh, my god. Oh, my god. I could hardly drive.

He aid, maam, will you just pull over there, please . I pulled to the side. I said, what is going on . He said, maam, the only thing i can tell you is your daughter has expired.

The attack did not look random. It was not rape, but it was so violent. That suggested rage. And when you look at at a rage murder, its usually somebody very, very close to the deceased. So naturally the first person they wanted to talk to was the man of the house, robert head, nikkis boyfriend. But robert wasnt around. When was the last time you saw robert . Yesterday. He left he bme in on sunday. He stayed for a day. He left. Heres the thing. Robert was a long haul truck driver which explained his absence, but not where he was, murdered.
