>> that's all for this edition of "dateline." > she was the love of my life. katie and i had a very special bond. always. >> we called the police station. we called some of her friends. nobody had heard from her. >> a daughter in danger. >> we were absolutely convinced foul play was involved. >> and no one could find her. >> i was concerned.

>> a daughter in danger. >> we were absolutely convinced foul play was involved. >> and no one could find her. >> i was concerned. >> we got to get going. we got to get moving on this. >> on the train coming home, she had met this woman. >> could a brief encounter hold the answer? >> she's talking about how someone has tried to assume her identity. >> there's more to this story, and you need to tell it right now. >> somebody was after her. >> true fear, i could really see it. >> hey, you all, come here. i think i found her. >> it began on a bright morning in may seven years ago. the "palmetto" slipped from its platform at washington's union station and eased out into an eight-hour run down the eastern

seaboard to charleston, south carolina. on board was a beautiful, tall and feisty redhead named kate waring, a daughter of the south, of a fine southern family. an often troubled young woman who was sitting on this train was finally on the brink of something very good. and what is it about trains? the ease there in that enclosed space of befriending perfect strangers. somewhere along the line between a greeting and good-bye, kate waring's invisible fate jumped its track. and quite unaware of the dark force descending, she disembarked to a future utterly changed. charleston, south carolina. it almost goes without saying is a show piece of american history and southern manners. its charm is deeply embedded as the families who count seven, eight, ten generations here. kate waring was born to one of those families.

grew up in a fine, big house along the historic waterfront called the battery. dance lessons, birthday parties. >> dad, if we catch a turtle, can we keep it? >> doting parents, janice and tom, who adored their own daughter. she had you essentially wrapped around her finger. >> oh, absolutely. she was the love of my life. and not stupidly so. i mean, i could not always tell when i was being manipulated, but some of the time. >> sure. >> no, katie and i had a very special bond always. >> she was the middle child. sandwiched between two brothers, older joe, younger richard. she was bright. maybe too bright. school bored her, animals, all animals, enchanted her. she was naive, sweet, as younger brother richard saw it, she could not turn away a stray animal or human.

>> she was a very, very kind person, whereas some people would dismiss someone who wasn't generally accepted by most, she would kind of try to help those people out. >> but somewhere in the course of an enchanted childhood, something happened to kate. outsiders saw a fearless tomboy morph into a sophisticated debutante. but at home, kate struggled often in secret with eating disorders, depression. college was a frequently interrupted disaster. >> she sort of ran toward risk. i noticed that in a lot of things that she did. she seemed to court it. >> her parents discovered she had been sexually abused when little by someone they knew. years of therapy followed. still she drank to excess, lost her driver's license, abused drugs, she sobered up, she fell off the wagon. she came home to live with her parents.

tried and failed at dozens of strategies to achieve the straight and narrow. finally out of desperation, tom waring offered kate a trip with him anywhere she wanted to go. anywhere on the planet to see polar bears. it must have been an amazing trip. >> it was the trip of a lifetime. i'm so happy we shared that together. >> the photographs show how happy she was there. >> she saw young men who were with their families about her age who were happy, and she said to me, "dad, i don't have to settle for what i've settled for, do i?" and i said, "no, honey, you don't. you can basically write your own script." >> and it was a bit of magic. the change seemed almost instant. kate reborn. on board the ship was a russian crewman who was amazed how quickly kate picked up his language which is why months

after that trip, the newly inspired kate traveled to moscow to meet him again, to explore the city, the culture, and to test drive both the budding relationship and her fledgling russian skills. the snapshots of kate in moscow were far more than souvenirs. they were portraits of a young woman transformed. the kate who stood here on red square had a new passion in life. the depressions of the failures of the past had fallen away. she was consumed by all things russian. in fact, she was making plans even her to return to moscow in the summer to take up russian studies. finally her life was taking off. and that's why kate waring was in washington that fine may morning. she was on her way back to russia. but there was a problem with the visa.

a paperwork mixup sort of thing that would have sent her into a tailspin once, but now, the new kate vowed to try again later. boarded the palmetto for charleston and once home threw herself into college classes and a children's book she'd been writing. big brother joe was, to say the least, encouraged. >> she when i talked to her was the happiest i can remember hearing her in the last ten years. she sounded good. she sounded as if she was ready, had a conviction about what she wanted to do. >> and then it was june. heat rising in charleston's deepening green. on saturday morning, june 13, tom waring at his summer house outside the city felt an absence. cell phone hadn't rung. no call from kate. kate who always called or texted her parents almost hourly. >> she always checked in and it was unusual. >> he drove home to check her room on this the silent house on the battery.

>> and all the lights were on, and it looked like obviously katie had planned to come back. and she'd left her medicine -- she never went anywhere without her medicine. >> and then on sunday, we came by the house also. no sign of her. >> now there was dread. was it possible that kate had slipped back into that old destructive life? >> we called the police station. we called the detention center. >> wow. so this is by the end of the weekend? >> nobody had a jane doe in the hospital. nobody had been brought in. we called some of her friends. and nobody had heard from her. >> what to do? kate was 28, and though she lived at home, she was an adult. her decisions, bad or good, were hers. they elected to give it one more day. if she wasn't back by monday, they'd call the police. then when monday came, there was word. no, not from kate.

from kate's bank. >> once i got off the phone with the branch manager, i called the police. >> yeah. what were you thinking then? >> i was thinking something is wrong. >> something was wrong, but could they discover what? and would the police help? >> i thought i'm not going to put up with this. we've got to get going. we've got to get moving on this. i think the reception for this product is overwhelmingly positive. this toothpaste sensodyne repair & protect can actually repair and protect sensitive teeth. and as long as they brush twice a day, everyday, then they can expect to continually have that reparative layer of protection against sensitivity. sensodyne repair & protect has clinical evidence showing how effective it works. i absolutely think that dentists are going to want to recommend sensodyne repair & protect. ♪ ♪♪ holy night

when you said youe, sir. were at the doctor, but your shirt says you were at a steakhouse...

that's when you know it's half-washed. add downy odor protect with 24-hour odor protection. downy and it's done. it was monday morning the 15th of june, 2009. kate waring had been missing for 48 hours when a surveillance camera captured a young man named ethan mack standing at the counter of a bank waiting to cash a check signed by kate waring. problem was her account barely totalled $100, and this check was for $4500, and the signature seemed off. the teller called kate's dad. he called police. >> i never met ethan, didn't know ethan's last name. all i knew was the name ethan who was a friend.

it's too strong to say that she had a secret life, but she certainly had friends and did things that we didn't know anything about. >> of course she did. she was 28 years old. and even though she was financially and emotionally dependent on her parents, she had lots of friends. some they knew, some they didn't. it was howard gatts, for example, a martial arts trainer in the midst of a contentious divorce with whom kate had been carrying on something of a romance. >> i felt that in my heart something was wrong. and i was -- i was concerned. >> then there was jason locke, a young lawyer with whom she often shared lunch and a spirited debate. >> she was strong-willed. she was very energetic. she was rarely, rarely incorrect.

that's a -- >> her best friend, as she made clear to all the others, was ethan mack. >> she really liked ethan. she really trusted him. "this is my best friend, jason." she put a lot of trust in him. >> she's a lovable person, full of energy, always rambunctious. >> ethan worked in a local hotel. a very different background than kate. but he'd been her best buddy for years and in a way her protector. everybody in ethan's neighborhood knew you didn't mess with kate when ethan was around. they loved each other like -- well, siblings. >> i made sure no harm would come to her when certain little boyfriends would act like they got hand problems. i would put them in their place -- >> it wasn't a romance at all then? >> never at all. she was like a little sister to me. >> it was a token of his family's regard for kate that she was godmother to ethan's nephew, malachi. on her moscow trip, kate bought

herself and ethan matching brass bulldog key chains. and on that monday morning in june, said ethan, he was very worried about kate, just as he had been for years as he helped her battle her demons. >> calm her down and talking to her and understanding what was going on in the world of kate. >> but now he complained, here was kate's dad sending the police to talk to him about a check kate told him to cash. ethan explained to the cop, david osborne, about the money he'd given kate for jewelry and other expenses and that the check was to pay him back. >> he was basically best friends with katherine, had been for several years. >> in fact, ethan told detective osborne he was very likely the last friend to see her before she disappeared. >> he said that he had saw her friday night, had dinner, had drinks, came back, dropped kate off back at her house. >> did he say what time? >> yeah. i think the time would have been probably around 11:30, 11:45 at that time. >> the detective checked, of course, and found text messages that confirmed what ethan told

him. he even went to the house ethan shared with his mom. >> and they both let me in. and they both allowed me to search it. the mother and ethan both told me this is his room, this is where he stays. >> but to say that the instant suspicion on the part of the warings and the police was upsetting to ethan was probably an understatement. >> good evening, mr. waring and mrs. waring. this is ethan mack calling -- >> this is the voicemail he left for the warings after that policeman poked around his place as if he was some murder suspect. >> i think you need really check that and go find out or go see what really happened and find the person who did something to her and stop harassing me. cause the only thing i ever did was try to help her in a million ways. >> so dead end. the police moved past ethan, checked kate's cell phone record, found she'd made a call late that friday that pinged on a tower in a place called james island, several miles from her

house. but phone pings can be funny that way sometimes, they told the warings. one tower's busy, the next over picks it up. probably made the call from home, they said. they also promised to keep looking for her. but really kate was known to have gotten herself in and out of trouble a time or two, and police resources were limited. and well, tom waring got the cops' message. >> we do not know for a fact that a crime has been committed here. >> after all, the warings were reminded, kate was a world traveler. could well have just picked up and gone back to russia. might be aboard some tramp steamer even now. or if something bad happened to her, could have been a drug overdose, even suicide. impossible, thought kate's parents. even in her darkest times, she'd never failed to call. >> if she spent the night out unexpectedly, we'd get a call first thing the next morning because she knew that we would worry about where she was and was she safe.

>> so the warings began picking apart that friday, the last day anyone saw kate, looking for something they may have missed. but it had been such a normal day. she had no driver's license, remember, so she asked howard gatts to give her a lift to her therapist's office. >> gave me a hug, said good-bye, thank you very much. she was in a real good mood. >> an hour and a half later, howard saw her again. this time at the gym. >> she said, is it okay i skip rope over here, howard? i said, sure, kate, that's fine. >> mind you, there was an incident at the gym. howard's soon-to-be ex-wife came around. she and kate had words. but at 8:00 p.m., a drugstore camera showed kate relaxed, talking on her cell, buying wine and snacks while waiting on her prescription refill. ethan paid for dinner. chicken, salmon teriyaki. >> like a japanese like -- kind of like cuisine-type thing. >> she didn't drive, so he took

her home. dropped her off before midnight. something earlier that friday that bothered the warings at first was terrifying them now. the more they thought about it, the worse it seemed. just before she went to the drug store friday evening, she started telling her father about some problem. >> saying that she felt like she perhaps had unintentionally got herself in trouble. and i said, "well, why don't you tell me about that." and she wouldn't tell me any details. >> was she clearly worried? >> she was concerned. >> clearly worried. >> about something. >> naturally they told the police about that. nothing came of it. and as the air thickened into a steamy august, the weeks that passed brought no new leads. just tourists clamoring for the cool shade of historic carriage rides. and kate waring, the urgency of finding her, began to fade. >> and that was driving me nuts. i thought, i'm not going to put up with this. we've got to get going. we've got to get moving on this. >> and in the hushed cool of his perch overlooking the city, someone was listening.

a new investigation begins. but it's not the police who are behind it. >> we're the cream of the crop, and our job was to find kate waring. not finding kate was not an option. >> who are these guys?

take a little drive beyond the grand old homes and markets and churches at the historic district center of charleston, south carolina. enter quietly the hushed suite of rooms overlooking the city where an influential philanthropist flipped through his mental roledex and placed a call to his friend, the chief of police. >> i really need a favor. i really need some help with this situation. >> the caller was this man, john rivers. happened to be a childhood friend of tom waring, watched kate waring grow up. john rivers told the police chief he was worried about kate, too. >> and he told me that, you know, they got a lot of stuff going on. >> sure. >> but that he would assign his best and brightest to the case. and i felt pretty good about

that. >> but now almost two months later, kate was still missing. and the investigation such as it was had accomplished nothing. and john rivers couldn't stand what it was doing to his best friend, tom waring. >> i could see that he really was having a hard time functioning. >> so rivers picked up the phone again and told this man, "do what it takes." his name is andy savage, former prosecutor, now famously tenacious criminal defense attorney. savage had heard about kate, too, and how police had no evidence of any crime. really? >> as soon as we scratched the surface just a little bit, we were absolutely convinced that foul play was involved. >> savage was given just two mandates -- find kate waring, tell police everything you find. that last part, keeping the police in the loop, should be easy, figured andy, given the team he assembled.

a band of retired policemen-turned-private eyes. each with a particular talent. >> bobby minter. >> bobby minter, human blood expert. tracking people his specialty. >> bill capps. >> bill capps, techno geek. tracks bad guys through cyber-space. happens to be a crack shot. >> james randolph. >> james randolph. ex-police department rebel. strategy his specialty. shaking things up a particular skill. >> we're the cream of the crop. and our job was to find kate waring. not finding kate was not an option. >> experience told james the best place to start was with kate herself. >> if we listen to kate, she'll tell us where she is. >> james went to the house on the battery, up the stairs, down the hall, and into kate's bedroom. >> these type cases, you have to

take on the personality, and you have to see this person's world through their eyes. >> he sat there for a bit, looked around. the russian notes in kate's handwriting made sense, but why chinese paper money? and why was her brand-new prescription sitting there untouched? >> the medication in which she had gotten for a prescription was still on her dresser, unused. >> that medication was her lifeline. she needed it to counter depression, anxiety, insomnia. she never left home without it. meanwhile, cyber-sleuth bill capps buried himself in social media sites. kate used them. bill scoured them all. >> if she was awake, she was facebooking, she was texting, she was calling people on the phone, she was e-mailing. and at the time she went missing, when everything immediately ceased, i mean, that was completely out of character for her. >> using kate's friends, capps built an electronic map of her communications the friday night she vanished.

from kate's friend jason locke, capps retrieved the weird voicemail left that evening. >> 10:06 p.m., missed call. voicemail. voicemail said that someone had "stolen her identity," and had obtained a couple of credit cards in her name. she wanted me to sue the person responsible. >> the gym trainer and kate's romantic interest, howard gatts, told capps he heard from her about 10:30 p.m., still at dinner with ethan then. there was another call. it was after midnight. well after police believe she was dropped off at him. >> she told me she was at some friend's house. they had already made it to the house. she sounded a little buzzed. >> and then a very last message from kate. a text. very strange. >> "i'm off to greenville to pick up some lovely." whatever lovely was i had no idea, you know, and, "i'll be back in a few days." >> did that make sense to you? >> no.

>> be careful, he replied. but this time she did not text back. silence from kate. except the middle of the night, her cell phone pinged out on james island, miles from her home. the cops had surmised, remember, that a closer tower to her house may have been too busy to handle the call. but at 1:53 in the morning? not a chance, thought andy savage. >> just preposterous. they were looking for an explanation, plausible explanation, consistent with their theory that she voluntarily left. [ ringing ] >> that middle of the night call, by the way, was to her voicemail. >> the mailbox is full -- >> the voicemail box that had been jammed full once during which time she hadn't used it or called it at all. so the question -- >> why would she call voicemail? she would not be doing it. >> only one conclusion to draw. >> somebody else was using her phone. >> but where was kate now?

had she as the one text suggested left town looking for drugs or lovely? if that's what lovely meant? for the moment, it was a dead end. and then -- then he called. eugene frazier, legendary 34-year homicide detective now retired. >> i believe that if a man commits a crime, he should be prepared to do the time. >> thing is about gene frazier, over here on charleston's james island where his ancestors go back to slave days, gene gets tips. all kinds of tips. and one day a church friend told gene he'd heard the police had been to ethan mack's house. and something strange about that. >> said, "listen, i don't think this is right," he says. "ethan mack is living in an apartment that i have rented out to his father."

>> but the police didn't search this place where ethan actually lived, said the landlord. they searched his mother's house on a different island miles away where ethan told them he lived. >> and he says, "i think that he's trying to mislead the police." >> what did you think when you heard that? >> this guy got something to hide. >> and on that very day, gene frazier joined a band of ex-cops which, from now on, we'll call the a-team. >> a mysterious woman enters the picture. >> katie had this strange girl in the room with her. >> who was she? the a-team was about to launch a hidden camera surprise. you've got to get in there, like...

i know what a bath is smile honey this thing is like... first kid ready here we go by their second kid, every parent is an expert and... ...more likely to choose luvs, than first time parents. live, learn and get luvs

by the time andy savage put his a-team together to look for kate waring, that lovely young charleston woman had been missing two months. according to kate's parents, tom and janice, the charleston police were still saying this -- >> they think maybe she went somewhere. she's probably just up in greenville. >> what did you say to that? >> she doesn't have a car. how's she going to get there? >> it was after that when the a-team's gene frazier got a tip. kate's best friend ethan lied about where he lived. he didn't live where he allowed police to search. he really lived in one of two apartments five miles away which you presented to the police. >> yes. >> and? >> they didn't search the house. they never got a search warrant.

they never asked for permission to search the house. they never said, "hey, you misled us two months ago." >> but as the a-team discovered, ethan failed to mention something else, too. he had a girlfriend in this little place, a woman named heather angelica kamp. and when janice waring heard that, her mind went straight to an afternoon at home three months earlier. >> i heard voices upstairs. and so i went up, and katie had this strange girl in -- that i'd never met before in the room with her. >> and that was her name, heather kamp. kate explained she met and rapidly became fast friends with heather on the train to palmetto during her trip down from washington. typical kate, janice thought back then. drawn to someone who needed help, who had told her a hard luck story. >> she said when she got on the train, her pocketbook was stolen.

and she's here in charleston, and she doesn't have any money. and i'm helping her out until she can whatever. >> but kate told her mother that heather would pay her back soon because she was a pediatric surgeon in charleston to take a new post at the local medical center. then a few days later, a distraught kate told her mother that heather's daughter back home in new jersey had been killed in a car accident. but something seemed odd about that, said janice. >> didn't seem like she was rushing to go up to new jersey to attend to the child that had been -- >> or that she was a grief-stricken woman. >> grief-stricken woman. she did not look that way at all. >> and now here was news that heather was living with kate's friend, ethan, in this tiny apartment. >> to me, she looked like a con artist. >> but no, said kate back then. janice had it all wrong. heather was nice. in fact, kate said she'd

introduced heather to her friend ethan and very quickly a romance had blossomed. they were even talking marriage. really? if janice waring was suspicious about heather back then, the a-team was doubly so now. sure enough a few key strokes on the internet told bobby that mother's intuition was right. >> she had been arrested for forgery in indiana. but she'd been arrested in other states, too. >> essentially if you just googled her name, i suppose you could find out a fair amount. >> that's how i found her. she'd been impersonating a doctor. i just googled her. >> and ethan wouldn't be her first husband. she had been married before and had four children. now that they knew about heather a few fuzzy details were suddenly clearer. the one thing -- the last dinner with ethan made more sense because there were three meals on the dinner bill. the other diner was heather kamp. and more important, that check ethan tried to cash, the one the teller flagged, maybe that was another heather forgery. right away, point man james randolph rushed that information

over here to police headquarters. surely somebody here would put two and two together. a woman known to have committed forgery in indiana and other states, a so-called best friend who tries to cash a bogus check with kate's name on it and lies to police. seems like evidence these two were involved in her disappearance up to their necks. enough to haul them in anyway, but -- >> i was told that the story panned out. and that these were petty criminals, and the check was going to be taken separate from the missing person. >> what did you say to that? >> i just didn't think it was the right thing to do. we had to figure out who wrote and endorsed those checks, who signed and wrote the checks. >> sure. it was obvious the a-team would have to find the connection between ethan and heather and

kate's disappearance without police help. >> sort of remained stealthy as much as possible. >> time to keep a careful, quiet eye on ethan mack and heather kamp. so gene frazier persuaded his church friend, ethan's landlord, to allow surveillance specialist bobby minter to tuck a hidden camera into the corner of the kitchen window. a camera trained right at ethan's front door. >> it was a motion detected just like the light that they've got over the door is. when they drove in, it would light up, and it would light up for our camera. >> the whole camera itself, keith, was about the size of this little flashlight. it was pointed directly at the apartments. >> that's pretty slick. >> no doubt about it. >> and that's enough illumination to illuminate to see what they would be carrying. and that would lead us to know that they had something to do with kate's disappearance. >> and when ethan and leather left the apartment, bobby had that covered, too. he'd already tracked ethan to his job at a local hotel and

attached a gps locator on his car as it sat in the parking lot. now there was no minute of the day when the team didn't know where ethan and heather were and what they were doing. and almost immediately, they got a surprise. when ethan was at work, heather sneaked over to visit the man living next door. rode around town with him. >> they were going to the bank a lot. and i called one of the investigators of wachovia. as a result of that, they found that they were kiting checks. they were actually stealing money from the bank. >> despite what bobby told the bank, it never resulted in charges against anybody. but that wasn't all he discovered. the gps tracker on ethan's car led bobby to a couple of local pawnshops. >> pawning jewelry. the jewelry was a red flag to us. >> was it kate's jewelry? they couldn't be sure yet without more surveillance, that is. and then the landlord called gene again, another tip. this one bad. ethan and heather weren't paying rent.

>> he says, "i'm going to evict these people." so after he said that -- >> this is not good news. >> i said, "hold on. if these people are evicted, we don't know where they're going." >> if the a-team didn't think of something and fast, heather and ethan might slip out of their sight and charleston for good. an enticing offer from the a-team. 10,000 reasons to start talking. >> 10s, 20s, 50s. everybody sees that and their eyes just jump. ng? it's dry... your scalp? mine gets dry in the winter too. try head and shoulders' dry scalp care it nourishes the scalp and... ...keeps you up to 100% flake free head and shoulders' dry scalp care

the team of retired detectives searching for kate waring had a big problem. crime-solving 101 told them heather and ethan had to be serious suspects. the last people to see kate alive. one a known forger, the other on tape trying to take money from kate's bank account. but they were about to be evicted for lack of a rent payment. and if that happened, they would slip the invisible net the a-team had so carefully woven. >> mind you, we had the camera, we had the gps, we've been tracking every movement that they have. >> so they made a call here to the quiet office overlooking charleston where the team's

money man, john rivers, decided he'd pay ethan's rent. secretly, of course. and it was a plan which after a little brainstorming offered a bonus, a built-in opportunity. here's how. the a-team wanted to know if heather or ethan forged kate's $4500 check, but they needed original handwriting samples. >> we determined what was on the check that we needed comparison samples to. and we had numbers, obviously, on the check. >> then the a-team helped ethan's landlord prepare ious that contained the numbers and letters. when ethan and heather signed the document, they provided the sample that could prove they forged kate's check. the team took the handwriting to mickey dawson, who set up the police handwriting lab. the question was simple -- did heather and/or ethan forge that check from kate, the one ethan tried to cash? >> immediately that day our handwriting document examiner said, "that's them. no question about it." >> so if ethan and heather forged a check from kate, what else did they do? someone on the team needed to get a look inside that

apartment. if kate had been there, there still might be evidence of something. but how to get in? >> well, the landlord has a right to inspect a tenant's homes for health and safety and welfare. and the landlord decided that he needed to go in and spray for bugs. >> you can understand why that might be done in that little place. >> james thought it would be best if he went with him to make sure that the bugs were all taken care of. >> surveillance expert bobby minter's gps device showed ethan's car was out somewhere. >> well, when we opened the door to go inside, ethan mack's sitting on the couch smoking a joint. >> for god's sakes. >> i'm like, hell, with the exterminator, we're going to be using dangerous chemicals. you'll have to step out on the outside while we get this done. >> no idea who you were? >> no, no, no.

>> you sure about that? >> absolutely. >> yeah. >> the exterminator and i went inside and closed the door behind us. just searched the apartment. and in one of the backpacks, in ethan mack's backpack, was some chinese money. chinese currency. >> chinese money? yes. just like the chinese bills james saw in kate's bedroom. janice waring had brought the bills to kate from hong kong, souvenirs. had ethan stolen them? time to stir things up. apply some pressure. bobby minter knew just how. >> bobby put on every telephone pole, every vacant house, every oak tree, every stop sign, "wanted: information, missing person, kate waring's" poster. >> where the people hung out. >> wherever they went, including on mack's windshield when he was working that day. we put posters to send a psychological message to them. >> but no response. at which point john rivers said --

>> perhaps what they do understand and on the street as it were is andrew jackson. and maybe benjamin franklin. and they would recognize their faces on a $20 or $50 bill. >> $10,000 worth of bills went into a grocery bag. >> 10s, 20s, 50s, and 100s. a bag with -- when you open it up, you know, two rolls and then everybody sees that. the eyes just jump. >> where better to leave that bag of money, they decided, than under the nose of the neighbor heather was going to see. the man named terry williams, the one who seemed to be kiting checks with her. >> we knocked on the door, and terry williams come to the door with no shirt on. >> uh-huh. >> no shirt on, short pants. terry, listen, we know you're great friends with these people, mack and kamp. you don't have to live in this

condition. we know you're back on your rent. we know -- look at that bag of money. this could be all yours. >> now to close the sale with terry williams, they try to bluff. >> tell us what happened to kate and where we can find her. we know mack and kamp killed her. and this money could be yours. and at that point, that's when the side -- the bedroom door busts open, and there's a lot of yelling and screaming. >> to their other surprise, there came heather kamp. angrily and quickly pulling her clothes back together. didn't appear to be a business meeting the team interrupted. the detectives told her who they were and who they worked for. >> and then heather kamp gets on the cell phone and makes a call to ethan mack. and says, "ethan, investigators are here trying to get terry williams to roll on us." and when she said that, the three of us looked at one another and -- police terms, we knew that was definitely the case. we knew, hey, they had done it. >> yes, decades of investigating made it perfectly clear to the a-team whatever happened to kate waring, ethan mack and heather kamp were in it up to their eyeballs.

>> we knew something was up. >> a new direction. the search for kate waring takes the a-team to a wild and desolate place. what would they find there? manolo! you're so cold, come in! what's wrong? it's dry... your scalp? mine gets dry in the winter too. try head and shoulders' dry scalp care it nourishes the scalp and... ...keeps you up to 100% flake free head and shoulders' dry scalp care

28-year-old kate warring has been missing since june 12th. >> it was so awkward now, but necessary. the once very private warings and their daughter's intensely personal struggles were so glaringly public. they had to be. >> you can't just sit back and hope that she'll be found. i mean, we worked every day all day long trying to find her. >> that's when it hit home. kate was the latest of hundreds of people still lost in south carolina.

and it seemed to janice and tom that police weren't taking cases like theirs seriously. what about all those other families also desperate for help? the warings held a vigil to make common cause. >> somehow or another, somebody will be moved and want to come forward and tell us where katie is. >> that was the public waring family. at home the private tom waring couldn't help but be drawn back to the play-back button on the voicemail. >> dad, mom? if you're there, pick up the phone. if you're there, pick up the phone. call me back later. bye. >> i would look at photographs of her or play those voicemail messages, just keeping her voice current in my mind. >> meanwhile, andy savage's a-team of ex-detectives was making progress. when they flashed that fat grocery bag of cash around the neighborhood, they certainly got

a rise out of ethan and heather. a furious ethan called andy. >> your investigators are out here. they're accusing me of being involved in this homicide. kate was my best friend in life. as he's on the phone, kamp calls. she starts out in this rage about, you know, what are you doing out here, accusing me of this, we had nothing to do with that. >> fascinating reaction, thought andy savage. and perhaps an opportunity. >> we had done a lot of background on kamp. and so we knew her and we knew her personality. we knew a little about what buttons to push. so the reaction we had toward heather was one of comfort. not one of angst. and during that time, we planted the seeds that as a mother she must know the feeling of janice waring missing her daughter and tried to apply to her empathy for a mother. >> the call from heather wasn't all that fat bag of money accomplished. before long, it reeled in a fish.

that neighbor heather was sneaking off to see called, too. the a-team went to talk to him. >> and he said, "i know ethan and heather did something to kate." and terry went in the back room, came back out, and had this ipod. and terry said, "i believe this ipod is going to belong to kate." >> now that was huge. the last time kate was seen with that ipod it was at the gym the day she went missing. now a man kate never met said heather gave him the ipod days after kate disappeared. just to be sure this was, in fact, kate's ipod, tech expert bill capps got the serial number. and within minutes, had the proof. >> i examined the registry files from all the computers that we had access to that kate had used in the past. we knew proof positive that that was kate's ipod.

>> of course right away the a-team told the police about the ipod and also handed over the handwriting expert's report showing that heather and ethan forged kate's check two days after she vanished. and now things started happening fast. i think the reception for this product is overwhelmingly positive. this toothpaste sensodyne repair & protect can actually repair and protect sensitive teeth. and as long as they brush twice a day, everyday, then they can expect to continually have that reparative layer of protection against sensitivity. sensodyne repair & protect has clinical evidence showing how effective it works. i absolutely think that dentists are going to want to recommend sensodyne repair & protect. ♪ ♪♪ holy night ♪ sleep in heavenly peace

she's been missing for months now. kate waring, a trusting young woman so eager to hunt those in need. the trail of clues has pointed to two of kate's friends and now private investigators believe they are close to solving the final part of the mystery. finding kate at last. but there are a few more twists in store. here again, keith morrison. >> the a team told police about the one hetser gave to a friend days after kate gave disappear

and also handed over the handwriting reports sewing that she forged a check. and now things started happening fast. after her hart to heart wieart andy, she called the police department and confessed. no, not to murder. instead it was she who forged the bogus check supposedly signed by kate waring and ethan who tried to cash it. now surely the police would swoop in and arrest them both. but here is something you should know about the way it worked between the a team and their former colleagues. the cops. the deal was entirely one way. that is to say the a team told the cops everything they uncovered. the cops told the a team nothing. so they kept their ears to the ground, waited for something to happen. but they didn't have to wait for long. >> we knew something was up.

so first thing we did was yank the gps off the car because we didn't want the police to seize the car and have our gps. >> ethan was easy enough to find. they arrested him at his hotel job. but they didn't seem to know where to find heather. so -- >> they didn't have surveillance on her. >> we told where heather was working. she was working at the sunoco gas station. >> i walked into the gas station and bought a pepsi. paid for it. walked back and police officer in uniform had pulled up and was peeping around the corner and i said that is her inside. >> ethan and heather were charged with forgery and obstruction of justice. would a murder charge follow shortly? >> we get a call that we have friends still at the police department, we get a calling

that may, polihey, police are s for kate eye body about that. >> isolated and 20 miles from kate's home on charleston battery. >> so i drove out there. >> and there were the police, a serious search going on. >> so i sat there in the shade and watched them all afternoon. didn't attempt to interfere. >> just watch the police to see what they were doing? >> lots of officers and cadaver dogs. >> a ton of folks. >> the cops brought heather here to lead them to kate's body. >> i did ask them any luck. and they just said no. >> police called off the search. drove heather back to jail. had she intentionally given them bad information? perhaps nobody would find kate. not the police, not the a team. and then --

>> we got a terrific break by the criminal justice system. mac and kent both came to the bond hearing and it is done by video. at the bond hearing, mac shows up with his family who were all there to support him. and not only a public defender, but the chief public defender. content oig noo kent noose o kent has no one. i immediately said go see her, treat her with kindness, treat her with caring. >> and within minutes the same man who had so upset heather with their bag of money were face-to-face with her. >> what was the look on her face when she came out? >> she was stunned. very surprised. and i said heather, we need help here. all we want is a body.

and she said any didn't find her, did they. i put them to the test. they told me they were going to help me. they wouldn't arrest me. and the minute i told them the area which she was, the general area, she got all abusive with me. they be 2krated me. so they failed. >> and what happened was shear luck. >> directly across the lobby in the male side of the visitation area, he's with mihis attorneys. >> and also coincidently, the jailer's position separated by gas partitions. >> she couthey could see each o? >> yeah, and i told her he's over there ratting you out.

so she starts waving her arms and snaps and breaks. >> with a little more encourage mts from ment from andy savage. his deal, if it turned out she had nothing to do with any murder, andy would pep hhelp heh her forgery charges. and at that moment heather agreed to tell the a team what they need to know. her directions were precise. they drove here right away. >> the oak tree that she described. and she says if you look farther up to your left in the marsh, you will see running down to the water and she says after you do that, you look to your left over here, and you will see some underbrush growing. and she said that kate -- she didn't say the body -- is five

feet from this path. >> incredibly detailed. just the sort of place to leave the body. but just like the police, the team found nothing. >> i was very disturbed. why are we not finding her? because we were convinced that she was here. >> they searched until darkness finally forced them out and then they called andy savage who was out of town on business. >> they were on a cellphone from where they are on a hotel in bost boston, the address. and i'm looking at the satellite imagery of where they are. i said well, james is there is a dock off to your left. so i was receipt well able to identify where they were. i said just print that off. >> isn't that amazing you can do that from thousands of miles away? >> you can also do it from the police station. >> the google map showed the a team how and where they lost the

trail. savage wasn't ready to give up on heather, you be wasn but he . >> we knew that she was a sociopath liar. i wanted something special from her. give me something that nobody else knows so that we can believe what you're saying is truthful. and that is when she told us about the souvenirs from kate's body, the jewelry she was wearing and where it was located. >> they found kate's jewelry at a partly sunny shop and behind the dresser in their tiny apartment kate's bulldog key chain, the one she'd gotten in moscow. ethan took it from kate's purse as a hmemento. so they decided the team would return to the island. >> all that we were believing was now coming to fruition, all our suspicious shns, we knew we

the right people. >> one things, maybe going without the police. good idea? maybe not. coming up -- the a team under arrest. >> what do you mean you were arrested? >> and we wouldn't leave because they seized high car. >> a twist even they didn't see coming.

the early sun had cooked the mist off the marshes. and now the air was heating up for another dripping hot day. bobby and built and gene shared a car from the city. they rode in silence most of the way. confident the precise directions heather camp had given them were

correct this time. so this was it. it was somehow fitting that bobby, the one they call the human bloodhound was the first to spot her. >> and i saw what looked like animal path where animals had pretty much beat down the bush.

we called 911. >> 911, what's the nature of your emergency? >> yes, ma'am, this is robert minter. >> okay, you need police, fire, or ems? >> police. >> what's the address? >> no address. it's in the woods. we found a body of kate waring. >> you believe you found the body of kate waring? >> yes. i know we did. >> in the woods? >> yes. >> listen to what happens after bobby hangs up. the 911 recording continues -- [ ringing ] >> you can hear the operator spreading the word around to other officers, a bit skeptical that the four-month long mystery is finally solved. >> hello? >> hey, sarge. you ready for this? >> no. >> this guy is adamant that he found kate waring in the woods off of polly point road. >> off of where? >> polly point road. >> all right. why is he adamant?

>> he says he knows it's her. >> out on the island off polly point road, the trio of former cops instinctively revert to the long practiced standard procedure. >> we said, okay, let's secure the crime scene, back out, wait for law enforcement to get here. >> so far, so good. but what happened next was quite a surprise. >> the first officer was a charleston county deputy. and i said, "we'll show you where the remains are." took him out there and said, "it's your crime scene now, and we're backing off." and that's what we did. >> but that wasn't the end of it, was it? >> no. >> no. we were detained to put it mildly. >> detained? >> detained, placed in separate police cars. >> what do you mean -- you were arrested or -- >> well, very strictly i guess by the legal definition, we were not free to leave. they made that clear. and, one, we couldn't leave because they seized my car. >> but wait a minute. you found the body. and showed them where it was. >> that's correct.

they wanted a statement from us as to everything that we had done from the very beginning. not just what we had done that day. >> the whole, long story? >> that's basically what they were asking for. and in fact, they had been given the story along and along as it occurred. >> hours later the ex-detectives were finally released. but not bill capps' car. didn't get that back until they filed motion papers for an injunction. even now the memory still rankles all of them. 34 years in the police department. to sit in the back of a police car and have some guy question you, get you to take a statement. >> that's right. like a criminal. that's what -- we were sitting in the back of a car like a criminal. let's call it like we see it. >> still, this was it. the news traveled to the house on the battery. the warings fell from their anxiety and into grief. >> mixed emotions. relief that she's been found,

but at the same time, devastating grief that now you have conclusive evidence that your only daughter is dead and that you're never going to see her again. >> and then as soon as they were allowed after the crime scene tape came down, after all the evidence was taken away, the whole team assembled at the spot where kate lay hidden for so long. all except tom waring, who did not want the image burned in his brain, the dismal place the love of his life lay dead. but perhaps it was a mother thing. janice had to be here, she said. had to see it. >> it helped me to see for myself it was so remote. we wouldn't have found her in a million years. and not knowing where she is, i mean, it's just -- it would have been horrible.

>> they formed a circle, held hands around the place they knew she had been. >> one of the investigators is a deacon in his church. and he said a prayer. >> this beautiful water, marsh, and docks. i think it might have given mrs. waring some peace thinking, you know, at least she wasn't in a garbage dump somewhere. it was a peaceful place, god's place. >> now the a-team had done its job, and kate's killers could finally be brought to justice. or so you'd think. but the mystery, the web that was spun on that train down from washington was far stranger, more bizarre than you have so far heard. and justice? well, we shall see. coming up -- they thought

they solved the case. but would it stick? >> we had a lot of opinions and conjecture, but actual evidence, it just wasn't there. >> and the close call that just might have saved kate waring's life. >> i always feel like if i could have hung on one more month, i could have helped them get her. >> when "dateline" continues. you've got to get in there, like...

i know what a bath is smile honey this thing is like... first kid ready here we go by their second kid, every parent is an expert and... ...more likely to choose luvs, than first time parents. live, learn and get luvs

this is the hour's top stories. a third day of anti-government protests in iran, there are unconfirmed social media reports of injuries and deaths. procetests are aimed at economi hardship and economic corruption. and the this morning times reporting how the russia investigation may have beaeeen sparked by george papadopoulous saying it began with a night of heavy drinking in a london bar which included a promise of dirt

on hillary clinton. now back to "dateline." most everybody around charleston, south carolina, seems to know who the county solicitor is. scarlett is what people call her. solicitor scarlett wilson, officially. a well-known and popular prosecutor. and solicitor wilson had a problem. actually, two problems. for one thing, though heather kamp practically leapt at a deal to turn state's evidence against ethan, her credibility, as you'll soon see, was not exactly aaa. and despite all the information the a-team uncovered, what could be used in court was thin. >> i mean, frankly, we didn't have a lot of evidence. we had a lot of opinions, and we had a lot of conjecture. but actual evidence, it just wasn't there. >> kate's skeletal remains gave

the solicitor none of the forensic evidence that juries like to see. and the coroner was unable to establish even a cause of death. as for those personal items of kate's that they found in ethan's apartment, those could just have easily been gifts. the two were supposedly best friends after all. and to top it off, there was the amazing tale that came with the state's star witness, heather. it's true she helped the warings' investigators found kate's body and agreed to testify against a man she revealed she actually married soon after the crime. but heather was also, as ethan's lawyer was discovering, a gray day world-class liar. >> not only was she a drifter. this was a true con artist with just the most horrid background of anyone i'd ever seen. i mean, a true sociopath. >> david ada was certain that heather on the train to palmetto took one look at kate waring and knew she'd found her ideal next mark. why was he so sure?

his research, he said, had turned up enough kamp victims to fill a small bus to the poorhouse. >> we had 13 different names that we could use. we called all 13. >> whoa. >> these were men and women all over the country. she would say that, you know, she was pregnant, she would say that her children had died of leukemia, that men had beat her. >> her scam -- troll the internet for men, latch onto one, move in, fleece him, and leave him with a mountain of debt. all the while pretending to be a doctor, an heiress or a mafia family. >> that was probably the worst whirlwind i've ever been through, seen, done in my entire life. >> there was chris beard, for example, in pennsylvania. >> just being around her made me feel better because that's what i wanted, you know. i wanted to be loved. >> he found her on the internet. in less than two months, they

were engaged, and she said she was pregnant. >> at the time that i had met her, i had no credit cards to my name whatsoever. >> she persuaded him to get 15 cards which she maxed out, leaving him $33,000 in debt. by the way, she told chris' sister-in-law, lori -- >> that she was a pediatric burn specialist and that she had worked with children. that was her specialty. and as lori had been having some behavior issues with her daughter, heather gave the girl a blood test. >> see if, you know, there was anything wrong with her. >> and -- >> she said, i want you to know that your daughter's bipolar. >> but it was odd. how would she know based on a quick blood test whether or not her daughter was bipolar? and why would heather use her own diabetes kit for the test? lori hit the internet just to check out the woman who was playing doctor with her child. >> and found that, you know, she actually was a wanted felon. >> she called the cops who arrested heather in the act of

spending more of chris' money. but somehow heather slipped off the hook. though lori pressed charges and pushed hard for a prosecution, nobody followed through and lori eventually gave up. lives with the guilt now. >> i think it was a month or so after i gave it up, that's when she came to d.c. and had met kate. and i always feel if i could have hung on one more month, i could have have helped them get her. >> now as he prepared to defend ethan, david aler was feeling much better. his crimes chief accuser, it appeared, was a practiced con artist. would any jury believe her? ethan might be naive, but his story, after all, had never changed. >> they had gone to dinner, he, kate, and heather. after they went to dinner, he dropped kate back off at her parents' home here in downtown charleston and spoke with her a couple times via text message that night.

and he didn't talk to her again after that. >> so it was all on heather. and with her as ethan's chief accuser, how could any jury convict him? but just days before the trial was to start, solicitor scarlett wilson finally uncovered something the case lacked. a clear motive. she found it, she said, in letters kate wrote to her friend before she disappeared. >> she's talking about how someone has tried to extend her credit limit or has tried to assume her identity and mess with her money in her bank. and she was livid. and i think kate was threatening to get her father involved. that was a new dimension. >> sure. >> for heather kamp. i mean -- >> didn't need katie as an enemy. >> and i have no doubt katie confronted heather kamp with that. >> and that, the prosecutor said, is when heather kamp and ethan mack decided they had to keep her from talking. kate waring had to die.

>> he began to make the choice to join in the scam to rip off kate waring. >> finally, the prosecutor scarlett wilson, felt ready. and almost a year to the day after kate was found she launched the trial of ethan mack. the sole defendant in the courtroom. heather having taken the plea agreement. the warings tried to prepare themselves, though what they saw defied preparation. >> we had to see images and see what it was like when they found her and then go through all the forensics. and we were seeing that for the first time along with the jurors and all those other spectators in the courtroom. >> one by one, the a-team took the stand, as did detectives and experts from the charleston police department, to present the evidence. >> over a stupid forgery. >> prosecutor wilson told the jury that ethan and heather killed kate to avoid getting caught for forging kate's checks and using her credit cards.

then heather took the stand and told the jury it was ethan, not her, who lured kate to their tiny apartment, then smothered her, shocked her with a taser, drowned her in the bathtub, and dumped her body out on wadmala island because he thought no one would ever find her there. did you think that you convinced that jury? >> i thought that the trial went better than i ever could have hoped. >> except, that is, for two things -- one, would the jury believe ethan actually killed his best friend, kate? and two -- >> heather kamp's a liar. heather kamp's jealous of kate. heather kamp's the one stealing. >> but heather's testimony did seem to terrify one person. ethan mack himself. and it showed. >> when he was in the courtroom waiting for the jury to come back, we have that picture of

him. what was happening with your client? >> at that point, you know, true fear. you know, true fear. i could really see it. >> what hold did heather have on this man? did the jury, did anybody, have this crime figured out? come being -- a surprise from the jury about that. >> his mother said there is more to this story. and you need to tell it and you need to tell it right now." it's dry... your scalp? mine gets dry in the winter too. try head and shoulders' dry scalp care it nourishes the scalp and... ...keeps you up to 100% flake free head and shoulders' dry scalp care

60% of women are wearing the wrong size pad and can experience leaks discover always my fit. find the number that's right for your flow and panty size on the top of any always pack. the better the fit, the better it protects. always. you just never can tell how a jury will react to the fact of a complicated murder case or the accusations of a person like heather kamp.

ethan mack cooled his heels while his jury tried to decide if he did or did not smother, beat, taser, and drown his best friend, the woman he claimed was like a little sister to him. and then after 14 interminable hours, they trooped back into the courtroom and told the judge they could not decide whether or not ethan was guilty of murder. >> what i'm going to do is on the murder charge, i'm going to declare a mistrial on that. >> mistrial, a hung jury. >> huge letdown. >> right. >> it wasn't going to be over. it wasn't going to end. we were going to possibly have to relive that whole event again. >> as she packed up her file, solicitor scarlett wilson vowed to find justice somehow. and then quite unexpectedly, there was an intervention from a surprising source.

it was ethan mack's own church-going, no-nonsense mother. she had testified during the trial for her son, of course. gave a hint then of what she was made of. >> corrine mack dean, d-e-a-n. >> ethan's sort of a mama's boy, isn't he? >> yes, he is. >> do you know anything about your son having any involvement with kate waring's murder? >> no. >> if you did, would you stand here and support him? >> he'd know i'd turn him in. >> then as ethan's mother sat through the trial, she heard things she knew her son, knew when he was hiding something. she went to see him in jail. ethan's attorney heard it all. so it did get loud in that cell when they were talking. >> he got confrontational. basically his mother said, "there's more to the story, and you need to tell it. and you need to tell it right now." his mother wanted him to tell the truth and tell what happened.

>> so it was decided. soon after ethan and his mother had their talk, he appeared before the judge and admitted he did participate in the murder of his good friend, kate. he agreed to plead guilty to voluntary manslaughter in exchange for a 25-year prison sentence. >> you understand that the court still treats this as a guilty plea. >> yes, ma'am. >> and that your criminal record will reflect that as a guilty plea? >> yes, ma'am. >> of course, since heather pleaded guilty to murder and forgery and obstruction of justice, they didn't need a trial for her either. guilty but mentally ill, by the way. at her sentencing, her counselor said she developed after a deeply traumatic childhood psychological disorders. some of which rendered her incapable of separating truth from her elaborate fictions and led to her years of failed marriages, abandoned children, and constant drifting. if heather was hoping for a shorter prison term because of

that, she didn't get it. instead, solicitor scarlett wilson noted she continued to lie about important details after she made her deal to testify. because she broke the deal, the sentence, 39 years. 14 more than ethan. >> this was heather kamp's kill. while certainly ethan mack was involved and certainly he laid his hands on kate, i do not believe that but for heather kamp we would be here. >> still, said andy savage after the fact, solicitor wilson could have had a much stronger case had the charleston police acted more aggressively. just one example, when police arrested ethan and heather -- >> because of their incompetence, they released the property, the crime scene where the homicide took place, they turned it back over to the landlord without examining it. the landlord went in and vacated the premises. he took all their furniture out and put it in storage. >> cleaned the place. >> cleaned the place.

it wasn't until over two weeks later, knowing that the property had already been tainted, the crime scene was destroyed. >> no wonder scarlett wilson didn't have all the ammunition she'd have liked, said andy savage. the charleston police said they didn't see it quite that way. they did take the case of kate waring very seriously, they said, right from the beginning. and the second-guessing from the a-team was rather puzzling. at least according to captain thomas robertson. >> i'm surprised. i really am. i think we both did a fabulous job, and i think the team of detectives that i had working from this agency and the support that we had is -- it was fantastic. >> what may have looked like inaction, said detective david osborne, was actually a careful and thorough investigation. one that didn't leave out any possibility. was there some point at which you thought this girl has -- she's probably dead? she's come to some serious harm? >> early on. >> early on? how many days after would you say?

>> i would say that -- i mean, within that first week for sure. >> yeah? so you knew it was a murder investigation at that stage. >> no. i mean, it could have been an overdose. it could have been an accidental death. i think we felt like we were probably dealing with a death investigation. >> right. but neither tom nor janice waring was the least bit satisfied. hadn't the police suggested early on that kate may simply have skipped town on her own? it didn't seem to the warings that they were trying very hard to find her. and what about all those other families of missing people, they asked? families without the resources to hire an a-team? >> unfortunately, missing people are low on the priority list nationwide. >> i feel like that a missing person or missing child should be just as important as a bank robbery because lots of people never find out what happened to their child.

>> it was late, after midnight, when she came to the end of her story. ushered there by two people she believed to be good friends of hers. and nobody, not the warings, not the a-team, not the police, has heard the story you are about to hear. the competing stories of the last hours and minutes of kate waring's life. question is, whose story will you believe? her long-time friend, the uncle of her godson? or the charming grifter, the woman who played with fate on the train? >> i had a big conscious and he doesn't. >> an evil lying type of person that would do anything she can to basically get her way. >> who was really behind kate's death? two very different tales. when "dateline" continues.

manolo! you're so cold, come in! what's wrong? it's dry... your scalp? mine gets dry in the winter too. try head and shoulders' dry scalp care it nourishes the scalp and... ...keeps you up to 100% flake free head and shoulders' dry scalp care

they call it the "palmetto," the train that glides down the eastern seaboard. eight hours from washington to charleston. fine setting to meet a stranger. sat in the same seat? >> sat in the same seat. laughed. were joking the whole way. started talking. >> heather kamp, freshly supplied with jewelry and cash from her last mark, just by chance found herself sitting with a young woman wearing jewelry and perhaps with access to such cash as heather had never seen before. what did you see in her? why did you like her? >> she was funny. very funny. >> now sitting here in jail, heather claimed she came to see kate not as her next victim but as a friend. and when in charleston she professed her love for kate's buddy, ethan mack, and then eventually married him, that love was true, too, so she says now.

and when she told them both all those well-practiced lies about being a doctor, about her husband and child being killed in an accident, et cetera, et cetera, those stories, she says, were just part of the schtick of, she admits it, of a con artist. >> that's what i do. that's who i am. that's the way i've learned how to survive. >> but remember, in court, the prosecutor called heather the mastermind who lied to con kate, lied to manipulate ethan. lied about murder. you were the decisionmaker, you were the person who caused kate's death. >> i don't take it as that. >> stole from her, yes. but kill kate? no. heather kamp will not cop to that. instead, this was the story the grifter had for us. it was all ethan right from the start. >> my husband wanted to rip her off because she had money. >> wait, why would ethan want any harm to come to his good friend, kate? >> the trouble was is that ethan never considered her a friend. >> not a friend of hers at all? >> no.

>> not like a sister or -- >> no. he was baby sitting her and she became a problem for him. >> became a real problem, says heather, when kate found out that she and ethan were stealing from her. >> she was like, "i'm going to put you guys in jail." and that scared ethan. and the whole nightmare began that night because he was not going to go to jail. >> so you're saying ethan was the mastermind, not you? >> yes. yes. >> and so after dinner that last night, said heather, they took kate back to their apartment. ethan got her a little high. >> after a couple of drinks, she was in a very good mood. >> there was a big suitcase on the floor. ethan dared her, says heather, get in. she did. didn't see the taser he was holding. >> he starts tasing her and doesn't stop. and by the time he removed the taser, she's not moving inside the suitcase at all. he races into the bedroom, grabs a pillow off the bed, comes back in.

pushes me away, unzips the suitcase, takes the pillow, compresses it over her mouth, grabs the wine bottle that is maybe four feet away, takes the wine bottle, crack, crack. i think maybe it's three times he hits her. he tells me to go inside the bathroom, start the water. >> she was terrified, she says. did you say, "ethan, stop?" >> i didn't say anything. >> didn't say anything at all? why not? >> i cried but i didn't say anything. i didn't know what to do. i didn't know what to say. when he told me to do something, i did it. >> she filled the tub, she says. >> he asked me to help her pull in there. i tried, but i can't do. i start crying, and i throw up in the toilet. >> why didn't you pull her out of the water? >> at that point, i -- the only thing i was thinking about was how am i going to make it out of this house. >> did you think ethan would

kill you, too? >> why not? who else knows but me? why not? why wouldn't i be next? >> she helped him put kate's body in the car. watched him dump her out on the island. of course she lied, she admits, when she told ethan she was pregnant. but that was just for the sake of her own safety, says heather. >> i thought, if i'm carrying his kid, i'm okay. he's not going to try to hurt me. >> really? so a moment later when asked why she didn't just leave ethan, slip away like she always did, she quite reverses herself. >> i didn't want to. i really loved him. >> eventually she says she just had to confess. >> conscious is a [ bleep ], and i had a big conscience and he doesn't. he doesn't have conscience. >> and that's the god's honest truth, says heather kamp, every single word. but there was another story to be told.

conniving, evil, evil, lying type of person that would do anything that she can to basically get her way. >> of course, it was different when kate brought heather around to see him that first time. >> she was attractive. >> talked, told him all kinds of things. >> she told me her son died from a disease that she was trying to help find -- >> the cure for? >> the cure for because she was supposed to be a doctor, and she told me that her daughter and her husband got killed in a bad car accident. >> ethan was entranced, he said. claimed he believed everything she told him. that's when they moved in together, and each day he'd go to his hotel job, and she'd head off to the hospital to her doctor work. >> she would be getting up, putting on make-up, putting on her scrubs, putting on her white jacket with her name that was sewed in it. >> but heather had another story, says ethan, one she had used on other marks.

but he didn't know that. that members of her family were violent and powerful drug dealers. and one day, he says she told him a terrifying story. her family members had learned that kate waring had sold out. she had ratted them out to police. kate was going to have to die. and those drug kingpins decided heather and ethan would be the executioners. >> she's saying her family basically telling her she better get rid of kate or they're going to get rid of us. and they're going to handle my family, too. they're going to kill my family. >> you believed this actually could happen? >> i done seen people get beat up over $5 and $10 and get shoot over for less than that. >> ethan's version of that awful night -- >> basically, heather zipped her up in the suitcase. that's when she came at me like, "ethan, we got to kill her." >> now right -- right then, ethan, she's lying in that suitcase, top is zipped up.

what you do as her friend is -- you go and unzip the suitcase and say, ha, ha, okay, get up. right? >> no, it wasn't -- >> that's not how it worked. why not? >> it wasn't like that. because my mother, my sister, my daddy, too, and my life -- >> but says ethan, it was not he but heather who smothered kate with the pillow. >> i couldn't do it to her or kill her. she had to push me out of the way, and she jumped on top of her and started smothering her with the pillow. i went into the room, and i dropped down on my knees. and i be like, "help me, father, please. forgive me for what is going on and what i'm witnessing here and have happen in front of my face." >> yeah. you were praying, but you weren't pushing her off, you weren't stopping it. >> no, i couldn't stop her. i still was thinking those people were going to kill me. >> let me challenge you for a minute because i know you're a good friend to her. >> yes, sir. >> you were killing your sister, for god sakes.

>> yes, it is. that's exactly what is right. >> the rest of it, the taser, the wine bottle bludgeoning, the drowning in the bathtub, all heather, says ethan, not him. and when he helped hide their crime, when he actually married heather, that, says ethan, is because she told him she was pregnant. she wasn't, of course. but ethan says he believed her as usual, and he wasn't about to abandon his child. yeah, but you're married to a killer. you got married to her after the murder. >> just for her to stop threatening me with the running off and taking my baby. >> god's honest truth, says ethan, every single word. and now at night in his jail cell -- how often do you think about that moment? >> i think about it a whole lot. i deceived her. i never meant anybody harm. now look at me. >> you getting exactly what you deserve? >> yes, sir. i'm getting exactly what i deserve.

i know i got to do this time in jail, but still i can't bring her back. wherever all the powers that i ask for, and how much i ask the heavenly father to take my life away to bring hers back, it will not be done. >> no. it will not. not for him. not for the warings. it was in court that kate's father, tom, read one of the last things she ever wrote. they had gone to church together, he and the daughter who adored him, the girl about whom he worried so. and she scribbled something on a prayer note and stuffed it in a church pew just a couple of sundays before she boarded that fateful train. >> she wrote, "please pray for my father, tom waring, who worries himself sick and for nothing. i am and will be fine. if i die tomorrow, i have lived through almost everything and more, and i'm not afraid of anything. just know that i pray for god's forgiveness for bringing tears to my daddy's eyes."

i'm craig melvin. >> i'm natalie morales. this is "dateline." they were so happy at first. romance turned to danger. she fell over the edge. accidental death. >> but it wasn't. >> she said you'll know who did it. a mystery of nearly 20 years heads in to court. the husband is on the precipice. >> did you kill your wife? >> i did not kill her. >> what happened on the cliff's edge.
