a dateline producer gets in touch with her on the phone. she tells sam her name is jessica traverse and she's a single mom living in texas. she sends him another photo. and without ever seeing him, jessica says she's ready to fly to new york with her baby and start a new life with sam if he wires $7500 to cover her edgese expenses. sam makes it clear he has the money. >> i've got some saving, i've got some savings. >> but unstead of wiring it, he says he has a nephew who can hand deliver the money. sam's nephew is really a producer and i'm going along. we have that photo she sent. so who is this woman? >> nice to meet you. >> i'm jessica. >> she says she's jessica. >> how are you? >> jessica? really? but before we get to that, we tell her we're concerned about 76-year-old uncle sam. >> so you've got my ukle all in an uproar. i don't know what you're doing. >> what do you mean?

>> no. i don't know where he is. >> he's in the wind. >> he might as well not exist. >> jessica hopes sam will be her knight in shining armor. >> i want somebody for a relationship, i can be there for him and he can be there for me, like a regular, good relationship, you know. >> remember, jessica has never met sam, never even seen a photo of him. even so, sam, she says, has already charmed her, but rest assured, she says, she's not interested in his money. >> i'm not about his money. i didn't care, if he makes me laugh. i just want somebody to be with me. >> wait a second. didn't she ask for money? >> you asked for $7500. where did you come up with that money. >> baufs airline tickets. i wanted to ship my car there. >> all without meeting this person face-to-face. >> i just wanted somebody to love me. >> such a row man particular, except now jessica has some explaining to do, starting with why she looks nothing like the woman in the picture she sent us. >> now this is the pose right here. and you see this is the picture that you posed in. >> mm-hm. >> that's not really you, is it? >> no. that's me when i was in high school. >> you think that's fair to post a picture that outdated? >> probably not. the reason i did it is i don't feel that good about myself. and so i posted that, so that way, you know, like maybe somebody would get to know me first. >> you could get somebody in the door. >> it's time for me to tell jessica who i am. >> there's something i need to tell you, that is i'm chris hansen from nbc. the good news is i'm paying for yu lunch. >> we'll pick up the tab. that's not the issue. >> remember, jessica told us those pictures were her in high school. >> it's a totally different person. look at the nose. >> did you have a nose job?

a real vampire? it might seem bizarre, but he's not the only one we found on the wild, wild web. this post gets right to the point. vampire seeks human donor. we respond, an a man named mike e-mails back. i will at times want to drain you and go. he agreed to meet our undercover staffer while hidden cameras record it all. but before they even begin talking, he asks for some wine, red, of course. our staffer asks him how he actually plans on taking her blood. >> would you bite me? >> no, i wouldn't bite you. >> he tells us he used a syringe before. that wasn't half as satisfying as when his exgirlfriend bit her lip. >> it was like so erotic, you know. >> obviously, that's not going to happen with our staffer. she excuses herself. and that's when i step in. >> hey, how's it going. i'm curious about this whole vampire phenomenon. >> okay. >> i just want to know about it. >> almost immediately, he realizes who i am. >> are you a reporter? >> i am. >> okay. >> how did you get into it? how does somebody wake up one day and say okay, i'm a vampire? >> you kind of awaken one day. >> as crazy as it seems, he appears to be quite serious about being a vampire. >> do you have vampires' fangss? >>. i don't. some people in the community do. they'll get fangs put in by dentists. >> are you sensitive to the light? >> no. nothing like that. >> he says drinking human blood rejuf nays him. >> you feel like you don't have enough get up and go. >> energy. >> like someone might have a cup of coffee in the morning, i take on someone's energy or tasted someone's blood, that would kind of like revitalize me. >> you can see where somebody unfamiliar with vampire culture would find this odd. >> correct, yes, of course. but it's not entirely unusual. >> he's right about that. we found many more people claiming to be real live vampires on the wild, wild web. here's an online post written by a woman looking for a donor in atlanta, georgia. she says her favorite color, not surprisingly, is red. and to anyone who want does reply but may be nervous, she'll throw-in dinner if it will help relax the nerves. we pose as someone who might be interested in quenching her first and set up a meeting in atlanta where she's a college student. >> how many times have you actually consumed somebody's blood. >> just not going to throw out a specific number but more than ten. >> what happens if you don't get a donor? >> you find other ways, you can supplement using animals, which i don't like to do. >> like a cat or a dog? >> rab is work best. >> what about humans? do you drink directly from the human body. >> it depends on the donor. there's a wrush. >> how many vampires are out there? >> there's a lot of us out there. >> and these were bona fide blood drinking vampires. >> some nice, some not. >> what do you mean? >> hollywood paints a nice picture. >> she says she's one of the nice ones and wasn't the least bit bashful knowing her secret will now be shared with millions. >> so i just had an interview with a vampire. >> you have. >> i can say that? >> you can say that. >> that's all for now. i'm chris hansen. thanks for joining us. i just want to know what his last thoughts were. what could you think? what could go through your head when you're falling to your death? >> it began so happily. >> we were young, passionate, it was nice. >> and ended so tragically. >> that's when i heard a woman screaming no. no. no. >> he was just 23 when he fell 17 stories to his death, leaving behind a pregnant wife. >> you actually watched him hit the ground. >> and questions. >> i still can't understand how it happened. >> at first, no one else could understand how it happened either, until someone started talking and just wouldn't stop. >> were you all both struggling? >> what do you mean? >> was this an accident? or something else? >> this is going to turn into a nightmare. it was a spring day in name only, the temperature in tulsa was a couple of humid ticks shy of triple digits. they were back where they met and had fallen in love. >> i believe everyone has that one person in your life that you give your whole heart to and there's no refunds or exchanges. >> the young couple, newly weds who'd recently celebrated their first anniversary had just survived a frigid winter in alaska, where josh had done a stint in the air force. she had spent most of the cold winter nights alone in military housing. >> it's really cold and dark. >> did you like it there? or did you quickly start feeling this isn't the place for me? >> it is hard to get used to. i would make grilled cheese sandwiches and tomato soup and sit on the floor in the afternoons and talk to levi. >> levi was the name they picked for the son they were expecting. amber was seven months pregnant. now, back home in tulsa, they were living in the city's iconic residential high rise. the view from their 25th floor apartment was one of the best in town until about 4:00 that hot afternoon. >> that's when i heard a woman screaming no, no, no! >> nathan was in the apartment next door. after the screams, he heard a loud crash. >> and i thought maybe somebody pushed over a coffee table or a fish tank, because it got completely quiet right at that
