"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. 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?

>> 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. when strangers on a train continues. are excited about the potential of once-weekly ozempic®. in a study with ozempic®, a majority of adults lowered their blood sugar and reached an a1c of less than seven and maintained it. oh! under seven?

>> 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. -and we welcome back gary, who's already won three cars, two motorcycles, a boat, and an r.v. i would not want to pay that insurance bill.

>> 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. coming up -- >> 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?

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. just to hear her voice. >> 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. coming up -- >> she said, well, they didn't find her, did they? i knew they wouldn't find her? hi! how was your day? it was good. it was long. let's fix it. play "connection" by onerepublic.

they said no and continued driving on. >> 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. mack and kent both came to the bond hearing and it's done by video. at the bond hearing, mack shows up with his family. >> yeah. >> who were all there to support him. and not only a public defender but the chief public defender. >> wow. >> kent has no one. she has no family. she has no friends. she has no support to speak on her behalf. >> yeah. >> i immediately said, james and jean, go see her. treat her with kindness. treat her with caring. >> and within minutes, the same men 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 surprised. >> stunned. >> stunned. very surprised. and i said, heather we need your help here. all we want is the body. and she said, well, they didn't find her, did they? she said, i put them through the test. they told me they were going to help them. they wouldn't arrest me. and the minute i told them the area which she was, the general area where she was, they got all abusive with me, you know? they berated me. so they failed the test. >> and just at that moment, what happened was, well, sheer luck. >> directly across the lobby on the male side of the visitation area, they brought -- to see his attorneys who happened to arrive the same time we did. >> just coincidentally? >> coincidental. >> also coincidentally, the jailers positioned ethan and heather across the hallway from each other separated by glass partitions. >> they could see each other? >> oh, yeah. there's the detective there with her. she's over there ratting you out. she's waving trying to get ethan's attention. so she snaps and she breaks. >> with a little more encouragement from andy savage, that is. his deal, if heather told him exactly where to find kate's body and if it turned out she had nothing to do with any murder, andy would help her with her forgery charges. and at that moment, heather kamp agreed to tell the a-team what they needed to know. her directions were precise. they drove out here right away. >> that's the large oak tree she described. then she says, if you look farther up to the left in the marsh, you'll see a dock that is running down to the water. and she says, "after you do that, you'll look to your left, over here on my right and left, and you'll see some underbrush growing." and she said, "that's kate's remains --" she didn't say the body, is 5 feet from this roadway. >> incredibly detailed. just the sort of place to leave a body. but, just like the police, the team found nothing. >> i was very disturbed. why are we not finding her? because we were -- we were convinced she was here. >> they searched until darkness finally forced them out of the marsh and then they called andy savage, who was out of town on business. >> they're on a cell phone from where they are. i'm in a hotel in boston. i punch up the address on google earth. i'm looking at the satellite imagery of where they are. i said, well, james, is there a dock off to your left? so i was pretty well able to identify where they were. i said, what you got to do is 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 clearly showed the a-team exactly where and how they lost the trail. after investigating so much, savage wasn't ready to give up on heather. but he wasn't naive either. >> we knew that she was a sociopath liar. i wanted something specific from her. give me something that nobody else knows so that we can believe what you're saying is truthful. that's 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 pawnshop. behind their dresser in the tiny apartment, kate's old dog key chain, the one she had gotten in moscow. ethan said heather took it from kate's purse as a memento. she was telling the truth. armed with andy's google map and more details from heather, they would return to the island. >> what we were believing was coming to fruition. all of our suspicions about her activity and mack's activity, at that point we knew we had the right people. >> one thing, they'd be going without the police. good idea? maybe not. coming up -- the a-team under arrest? >> what do you mean you were arrested? >> we were not free to leave. they made that clear. >> this was a twist even they didn't see coming when "strangers on a train" continues. year, i am sorry about that. [music playing] (vo) progress is in the pursuit. audi will cover your first month's lease payment on select models during summer of audi sales event. gene frazier shared a car from the city. they rode in silence most of the way, confident the precise directions heather kamp had given them were correct this time. so this was it. it was somehow fitting that bobby, the one they called "the human bloodhound," was the first to spot her. >> i saw what looked like an animal path. where animals or something had pretty much beat down the bush. so i walked up to the animal path and started walking parallel with the road. and walked up, and i saw what looked like bones. and i said, "i think i found her." i said, "hey? hey, y'all, come here. i think i found her." it was just like a ton of bricks came off me at that point. i said, "oh, my god. there she is." you know, wasn't much left. just bones. >> in the end it took only six minutes to find the earthly remains of kate waring. and thus, at last, fulfilled their promise to her parents. >> i saw where bobby was standing, and i took two shots with my camera just to document the scene the way it was when we saw it. then i just backed out of the woods, and bobby followed me out. 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. wadmalaw island. >> 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 took my -- 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, years later, 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, you know, 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? >> actual evidence, it just wasn't there. >> and the close call that just might have saved kate waring's life. >> if i could have hung on one more month i could have helped them get her. when "strangers on a train" continues. new customers bundle and save big, but now it's time to find my dream abode. -right away, i could tell his priorities were a little unorthodox. -keep going. stop. a little bit down. stop. back up again. is this adequate sunlight for a komodo dragon?

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 the daughter of a mafia-style drug 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, he said, 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 issue 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. >> so 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 she 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 she prepared to defend ethan, david aler was feeling much better. his client's 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 just 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 -- >> she 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. so, 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? coming up -- >> please raise your right hand. >> a surprise from the jury and another one from ethan mack's mom. >> he got very confrontation on. basically his mother said, "there's more to this story. and you need to tell it and you need to tell it right now." >> when "strangers on a train" continues. with chantix. i tried cold turkey, i tried the patch. they didn't work for me. i didn't think anything was going to work for me until i tried chantix. chantix, along with support, helps you quit smoking. chantix reduced my urge to smoke. i needed that to quit. when you try to quit smoking, with or without chantix, you may have nicotine withdrawal symptoms. some people had changes in behavior or thinking, aggression, hostility, agitation, depressed mood, or suicidal thoughts or actions with chantix. serious side effects may include seizures, new or worse heart or blood vessel problems, sleepwalking or allergic and skin reactions which can be life-threatening. stop chantix and get help right away if you have any of these. tell your healthcare provider if you've had depression or other mental health problems. decrease alcohol use while taking chantix. use caution when driving or operating machinery. the most common side effect is nausea. i can't tell you how good it feels to have smoking behind me. talk to your doctor about chantix. extra." i'm craig melvin. ethan mack awaited a jury verdict. would they find him guilty of murdering his best find kate waring or would they set him free? and what about the stranger kate waring met on a train, heather kamp? here again is keith morrison. >> 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 today and support him? >> he'd know i'd turn him in. >> then as ethan's mother sat through the rest of the trial, she heard things. she knew her son. she knew when he was hiding something. so she went to see him in jane. ethan's attorney heard it all. so it did get loud in that cell when they were talking. >> it got very confrontational. basically his mother said, "there's more to the story, and you need tell it. 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 it 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 attorney her therapist told the judge that 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 own incompetence, they released the property, the crime scene where the homicide took place, they turned it back over to the landlord without examining. 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? coming up -- heather versus ethan. >> i had a big conscious and he doesn't. he doesn't have a conscience. >> who really was behind kate waring's death? two very different tales. wen "strangers on a train" continues. if you use some of these moves way too often... then you might have a common condition called dry mouth... which can be brought on by many things, like medication and medical conditions. biotène provides immediate, long lasting relief from dry mouth symptoms. it is clinically proven to soothe and moisturize a dry mouth. plus, it freshens breath. biotène. immediate and long lasting dry mouth symptom relief. returning to "strangers on a train." the trial was over. the killers in jail. but it was not the end of the story. in fact, there were two sharply different tales about the last hours and minutes of kate waring's life. you're about to hear the first. once again, keith morrison. >> 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. we 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. >> but 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 babysitting 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? i didn't know what to do. i could hear him screaming, "help me!" and there was nothing i could do. of course she hides when she told ethan she was pregnant, but that was for her own safety. >> i thought if i'm carrying his kid, i'm okay. he's not going to try to hurt me. >> really? and so then a moment later when asked why she didn't just leave ethan, slip away like she always did, she reverses herself. >> i didn't want to. i really loved him. >> and eventually she says she just had to confess. >> conscious is a bitch and i had a big conscious. and he didn't. >> and that's the truth. every single word. (door bell rings) it's open! hey. this is amazing. with moderate to severe ulcerative colitis, are you okay? even when i was there, i never knew when my symptoms would keep us apart. so i talked to my doctor about humira. i learned humira can help get, and keep uc under control when other medications haven't worked well enough. and it helps people achieve control that lasts. so you can experience few or no symptoms. humira can lower your ability to fight infections, including tuberculosis. serious, sometimes fatal infections and cancers, including lymphoma, have happened; as have blood, liver, and nervous system problems, serious allergic reactions, and new or worsening heart failure. before treatment, get tested for tb. tell your doctor if you've been to areas where certain fungal infections are common, and if you've had tb, hepatitis b, are prone to infections, or have flu-like symptoms or sores. don't start humira if you have an infection. be there for you, and them. ask your gastroenterologist about humira. with humira, control is possible. -we're in a small room. what?! -welcome. -[ gasps ] a bigger room?! -how many of you use car insurance? -oh. -well, what if i showed you this? -[ laughing ] ho-ho-ho! -wow. -it's a computer. -we compare rates to help you get the price and coverage that's right for you. -that's amazing! the only thing that would make this better is if my mom were here. what?! an unexpected ending! >> evil lying type of person that could do anything she can to basically get her way. >> of course, it was different when kate brought heather around to see him that first time. >> she talked -- >> 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 knee 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, 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."
