legally have to let them let me go with them, like if my mom showed up. >> max was scared, had no idea what was going on with his mom. he wanted to stay with his grandparents. >> i have heard all these horror stories about people having these personality changes. and going off the deep and. and i thought, i've got to do something about max. i've got to keep him safe. >> nancy applied for temporary guardianship of max. >> that must be so weird? >> oh. >> fraught? >> yes. i'm just wondering, what am i doing to my daughter, if we were doing this, the lawyer said, now, this is just temporary. she comes back, you can always undo this. i said, okay. >> meanwhile, surely the sheriff could find her daughter with some help. she showed them cari's texts about the furniture. the phone company said they

were coming from a location in omaha. officers went there. no cari. >> sergeant jim doty and ryan avis of the pottawatomie sheriff's office who joined the investigation much later, said the next step was to find the women who paid for the furniture. her name was shanna golyar. >> we called her. went to voice mail, which she returned that call the next day. >> shanna went by her middle name, liz. and it turned out that was the same liz dave kroupa once dated. she lived in omaha with her two kids. liz told the cops that somebody stole her checkbook, and she suspected that somebody was the woman she ran into at dave's place. liz took his contact information. >> she is with, him suddenly, she goes off the rails, and starts doing weird stuff like this. so, you must know something here. >> yeah, definitely the person you want to talk to. >> and by then, the story dave could tell the police, scary.

>> dave kroupa was upset. maybe as upset as he'd ever been. ever since he told cari that she couldn't move in with him, she had been texting and emailing and saying awful things, and making his life miserable. he tried calling her, but she didn't answer. and then, a little more than a week later, the cops showed up at his auto repair shop. >> how did you find out they were there? they just showed up? >> yeah, there was no warning. >> the detectives took him outside for top. they >> told me, do you know cari? i was like, yeah, what? when did you see her last? the morning of? okay, where is she now? i have no idea. >> the detectives didn't seem to buy that. >> he was drilling me with the policeman eyes, the ones that are like, you know, -- >> where were you at 6:30 on that morning? >> yeah, no, i totally had the

feeling -- >> she was at your house. you are the last one to see her. >> and that was how he approached me, it was as if i had already done something, and he already knew it, and it's time to deal with it, you know? and i was like, whoa, whoa, slow down. >> david tried to explain, he said. >> hey, man. i don't know where she is at, but i have nothing to do with it. you know, i don't know where she's at. and i don't want to know where she is at that point. i just wanted her to go away. >> because dave told detectives, cari would not stop messaging him. he showed him his phone, and was adamant he had not seen her since the morning he left her at his place. >> do you think they believed you when you said you didn't know where she was? >> 100% they believed me. >> and then, the strangest thing, cari started texting the detective too. i would really appreciate it if you leave dave kroupa out of it. the detective texted cari back. >> we can't stop looking into

it. we need to locate you, and a missing person entry won't be taken out until someone talks to in-person. to where we know you are okay. >> did she respond to that? >> she said it was pointless. >> she didn't want to be found? >> exactly. >> but the detective got another text. this one seemed ominous. i want one person to go away for destroying everything for me. who might that person be? the detective had a pretty good idea. dave showed them texts in which cari blamed liz for their breakup, even though, as he explained, he and liz weren't even together, when he met cari. it made sense of that cari must have stolen liz's checkbook, maybe even forged that check for five grand. the detectives called liz right away, and told her she should

follow report with the omaha pd. it was their jurisdiction. but before she got the chance, liz went to her garage, and there, sprawled on the wall, she found the words, whore from dave. all of it was so strange, thought detectives. >> it's pretty hot. >> like maybe she'd had a breakdown or something, like a psychotic episode. >> that would be the only answer. >> to the police in omaha, cari was now a suspected stalker. back home, in pottawatomie county, iowa, she was still a missing person, with a very worried family. cari's mother heard about the threatening texts, the harassment, the police reports filed against her daughter. to her, it didn't seem like cari at all. and it made her wonder. how serious were the police about finding her daughter? >> i got a little callous towards the authorities. i was thinking that, i didn't think they were doing what they should have been doing. >> do you get the feeling, they just want to get in there and

storm the barricades, and make something happen? >> yeah. again, i didn't know how much i can do. i didn't know where to start. >> cari had been gone for almost two weeks. thanksgiving, a day away. nancy said cari message her on facebook. >> i've got a roast in the crock pot, and we will eat about six. we are going to dads for thanksgiving, and eating about noon or one. we love you, cari. cari didn't respond, and didn't show up for thanksgiving dinner. less than a month later, nancy's ex husband, cari's father, died of cancer. cari didn't come to the funeral. instead, she sent a message on facebook, i am sorry i missed the funeral! just a few days before that, she posted on facebook, david kroupa proposed to me. i said, yes. what in heaven's name was going

on. nancy called the detectives who called dave, who swore, no way he was engaged with cari. he said he hadn't even seen her, but still heard from her constantly, a hail of texts and emails that was only getting thicker. >> i would receive 50 - 60 a day. >> a day? >> yeah, all day long. at one point, my phone was completely useless. it will just be running so much, i just couldn't answer a phone, or send a text. >> like why don't you change your phone number? >> i did that a couple of times. >> you did, and it still kept coming? >> they did. >> occasionally, cari's texts seemed almost normal. i know i ruined it. i tell myself don't be crazy this guy was nice to you but something takes over. but mostly, the emails and messages were angry texts, about perceived romantic rivals, miss golyar in particular. >> she is a whore, you shouldn't be with someone like that. i hope we can see each other soon. and then, with a shutter, they

realized cari did see him. she seemed to be watching this every moment. it was very traumatizing for me to get messages, emails, to say, i see you through your window. you are doing this. i'd go, i am doing this. okay, great. now haul butt outside, you are looking for somebody, because somebody knows what i'm doing. >> even more disturbing, cari messaged dave that she had taken his extra apartment to, and had been coming and going when he was going when he was not there. liz got unsettling emails too. i am out in your garage, so what should i do to your car? i see my handiwork is still on the wall. attached to the email, a photo, to prove cari was there. eventually, the messages got threatening. cari wrote dave a note, claiming she kidnapped liz. you will do exactly as i say, and then, i will let her go. do it or say goodbye to her. attached was this photo.

the worst, said dave, this crawling feeling that she was stalking him, spying on him. but always, like a ghost. and in a look, she was gone. then, one day, about two months after it started, dave was starting home from a shop. >> i come into the parking lot. and i noticed the truck there, because it still had all the snow on. and when i got close, i said, it's an explorer. it's the right color. so, i called the sheriff and said, i'm pretty sure i found her truck. >> he was right. it was cari's suv, still half buried in the snow. >> they impounded it. we had a crime scene tech process it. and it was really clean. >> they did a thorough investigation? >> yeah, they invested it for prints, they found a fingerprint inside, we covered that. >> the fingerprint was found on a mint container in the cup holder of the suv. they ran the print through the national database. no hits.

but if cari wasn't using her suv, at least, certainly not daily, her presence was unavoidable as ever, through those texts and emails, threatening photos, sent to both dave kroupa and liz golyar. now, the detectives made sure to do a phone check from both of their devices to preserve the evidence, and perhaps, figure out where she was. it was even a link to a fake obituary for liz. see what i made for the horror? i will kill her, and i already made her an obituary, so it's done. then, minutes later, i'm trying to hire someone to get rid of that whore liz for us. you told me before, you wanted her gone. do we want to pay just for the bitch or the two kids too. i hope to see you soon. your beautiful cari. >> trying to enlist you in her scheme, to kill liz. >> yeah, that was a very

interesting breed, the first time ever thought. i was, like oh my god. what in the hell? >> cari didn't seem to realize that her ongoing harassment was actually pushing dave and liz back together. >> i compared notes on the harassment? >> spent hours talking about it. sending each other texts and emails, now -- >> kind of comforting each other. >> i mean, who else would understand that? >> exactly, nobody else did understand. >> now, dave and liz were regulars of the omaha pd, filing one complaint after the other against cari. at the time, they reported that cari broke dave's apartment window and that's when the detective stepped in to investigate. >> he said, yeah, it's her, she's done to me before. and fights photos of her, shows me some text messages, and she had made a text referencing the fact that she broke out his window. >> he could see the attacks were escalating from angry texts to theft, and then vandalism, and then threats to physical harm. he obtained an arrest warrant

for cari farver, not that he had much hope of finding her. he knew cari was a computer expert, probably using software to discuss the phones and computers for messages came from. >> i thought, well, maybe, this must be some kind of avenue she is utilizing, because, nothing is there, we can find her. >> weeks passed, and each time dave and liz were hit with an even more outrageous barrage, lagreau would look again, and again not find cari. and yet, it all seemed to be leading somewhere bad. >> were dave and liz afraid? >> oh, yeah. it's not so much you are terrified of the individual. it's like, you are on edge, what's gonna happen next? >> and sure enough, what's happened next was terrified? >> early saturday morning, august 17th, liz called dave, frantic. >> the house burned out.

oh my god, it is that crazy person cari stalking me again. liz has been in the middle of moving out. she undercuts were already sleeping on the new place when she went back to the old place that saturday morning to pick up more of her things. instead, she had to call the omaha fire department. they responded right away. later, so did detective lagreau. >> inside the house is pretty charred and burned, and pretty sufficient. really could've ended up turning burning the house, but just didn't quite get to that point. >> but it was deadly enough. liz had two dogs, one cat, and a pet snake, all we're still in the house. all of them were found dead. across the street, they saw women in a car parked outside liz's house a few weeks before the fire. detective lagreau showed them a photo of cari. the neighbors said they couldn't be sure but she had the same general appearance. with an email to dave made no secret of who did it, i am not lying.

i set that nasty whore's house on fire. i hope the whore and the kids die. and later, hope you and your kids burned to death. >> we are getting into situations like arson, threats to individuals lives, or those around them, their children, the ex-boyfriend. certainly, you are gonna take that much more seriously. >> suddenly, the case against cari was very serious indeed. but still, like smoke from the fire, she vanished. >> what i did was try and find some way, somebody saw her, and then, came up with nothing, over and over again, nothing. >> this time, said day, he was afraid to try to attack his kids but too. what did she say when she threatened your kids, for example? >> oh, something along the lines i would slip your children's throats. >> wow! >> that's pretty hard to read.

>> it took a toll, said dave. >> for a while, i was drinking heavily, which is not me. never been a time in my life where i was a real drinker, and i was a drinking until the bar closed, and going to start again at 6:00 in the morning. >> wow, and you bought a gun? >> sure, yeah. >> why? >> for my safety and my children's safety. for just protection in general, i was like, i didn't know. >> so, dave and liz kept watch in the city, wary, fearful. back in macedonia, cari's family was hoping with a whole different set of emotions, emptiness, grief. and a terrible knowing uncertainty. nancy had sent several pleading messages, come home. cari, you are my daughter, and i always love you no matter what. we just need to see you, hear your voice, know where you are. i love this so much. you're my little girl. come home. >> for a parent, for a mother, i don't know how do you characterize this episode in

your life? >> how do you talk about those feelings and make sense of them? >> there was no sense of it. there was no making sense of it. >> what's happened to cari farver? and why? >> coming -- up news like a lightning bolt for a family in anguish. someone claims have seen cari. >> my heart was just racing like crazy. >> could it be, after all this time? >> did you rehearse what you would say when you saw her? >> where have you been? >> when dateline continues. and can help you breathe better in as little as 2 weeks. dupixent is an add-on treatment for specific types of moderate-to-severe asthma that's not or sudden breathing problems. dupixent can cause allergic reactions that can be severe. get help right away if you have rash, chest pain, worsening shortness of breath,

>> they said, we'll check it out. that kind of thing. >> nothing came with it. but after karen's father died, her ex-husband, she had this weird dream. he came to me very vividly in the dream. . he said, don't worry, nancy, she's with me. that sounds silly, but that's when i knew that -- because i knew she just would not just vanish. >> but of course, nancy did not know for sure. >> and every time something would pop up online, or we'd get a text or something, there was this hope that maybe she is still out there. >> max was looking for answers

his own way. about a month after nancy went to the shelter in omaha, max sent his mom a message on facebook. hi. that was it then the next day, cari responded. hey, little man, how are you? max messaged back. i have three questions. >> things only she would know. >> things only she would know. >> max asked, one, what is my middle name? two, what was our first boxer's name, the dog? three, who was my best friend as a little kid? >> and what was the response? >> nothing, i never got a response to that one. >> which meant what? was that his not in her right mind mom? or could his grandma be right? that somebody had kidnapped cari? there's no way of knowing, really. and the messages kept coming. like this one, from cari's mom.

>> i'm not hurt, mom, i miss everyone too. i just had a breakdown, and i think i'm getting over it. i should've came to my senses sooner and realized the guy was not worth it. and then following year for mother's day, happy mother's day, mom. how has max been? nancy, frustrated, replied, call me and i will gladly tell you about him. this is not talking. i need to hear your voice. >> cari never called. >> for nancy and max, the anguish of missing cari never stopped. and meanwhile, all dave croupa won it was to escape her. in february of 2015, they've moved from omaha to council bluffs, iowa, across the river. his kids lived there with amy flora. and he wanted to spend more time with them. and he hoped cari would not find him there. he bought another gun just in case. and after about three years of relentless harassment, things finally seemed to be quieting down for liz and dave. they were not as many messages from cari, she seemed to be fading away.

and as that happened, liz and dave saw each other less and less too. there was just one rather scary thing. that gun dave bought for protection, the one he kept hidden high in a closet, disappeared. and you're the only guy in that apartment? >> right, i'm the only one living there. niw my mind is racing, there's no forced entry, the doors all shut and locked, -- >> what did you think? >> i don't know what the hell to think. >> meanwhile in pottawatomie county iowa, before cari live before she became a dangerous digital persona, her disappearance was more office chatter and then active case. that's when these two detectives got hooked on it. >> we heard some stuff, you know, just water cooler talk about the case. >> about the strange crazy woman? >> it was interesting. >> it piqued our interest. so we requested to take a look

at it. >> that was april 2015, more than two years after cari's reign of terror began. the file was huge by then, and bizarre digital house of mirrors. so, daughty and avis decide to sort things out, beginning with a very simple question police had never really considered before. though, her family certainly had. was cari farver really the vengeful woman she seemed to be? or, did she even exist? >> i thought the smart idea was not to have tunnel vision in any direction. so, ryan walked in as if cari was still alive, and he was going to work it until he came to a dead end. i was going to work it like she was not alive. because there is things that would lead us maybe to both conclusions. she still active sending text messages, pictures. >> certainly seems alive. >> but she's also lying, and has missed so many events, and has it been physically seen by anyone. >> we started from scratch. rereading.

>> reviewing all the old material? >> reading all the reports, looking through those phone downloads, listening to any interviews that had been recorded, just diving in. >> of course, they spoke to dave kroupa. no doubt in his mind cari was alive and crazy. >> he was transparent. he gave access to his whole email account. >> 11,000 emails that he had saved over the years. could be more. >> that was not all they had. right there in the file was a wholesale dump of material from liz golyar's cell phone. so there were learning a lot about both dave and liz. they had been immersed in all that for months, but had not interviewed liz yet, when in the office one day, pure coincidence. >> i was in the hallway talking with a county attorney, and another investigator was walking down the hall with liz to his office. >> wow. >> and to me, it was like i saw a famous person.

and i knew everything about her. and she was there to file a harassment report. >> but this was odd, her complaint was not against cari, it was someone else. >> amy flora, that's the mother of dave's children. >> wait, amy? not cari? first detective avis did a psychic double take. and then he asked if he could be the want to interview liz. >> who is your ex boyfriend? >> dave kroupa. >> dave cooper? >> k - r - o - u - p - a >> and he has kids with amy flora? >> liz told detective avis that her on again off again relationship with davis off again. but ever since their most recent split, dave's ex amy had been stalking her on facebook, and she was very worried because -- >> not even two days after you broke up, his apartment is broken into and his gun was

stolen. so, i told the police officer i was kind of worried that -- since she has a key to his apartment -- >> that, says liz, is when she suddenly realized that she and dave had been played for fools. for three years, she believed cari was the woman behind all the threatening messages, the harassing graffiti, the deadly fire that killed her pets. but suddenly it was a like a light went on, said liz. it wasn't cari at all. that scary awful online villainess that was responsible for all the trouble had to be amy flora, dave's ex, the mother of his children. diabolical. but think about it, said liz. amy was the one who so desperately want it dave. she had the motive. but cari? not really. >> like i said, they only dated for two weeks, and i don't understand why a person would still be stalking him almost three years later. >> cari and dave dated for two weeks? >> yes.

>> and she -- >> supposedly is the one stalking for three -- three years. i would find it more reasonable to believe that his kids'moms is the one that's -- >> head spinning, detective avis made some notes, told liz he would do what he could to help her out. and no surprise, the very next evening, december 5th, liz felt like she needed some time alone to think. she drove out to big lake park, took a walk around the trailer, sat down on a bench, quiet, alone in the gathering cold and dark. and that is when it happened, the deafening bark of a gun and the pain tearing through her thigh. >> i've been shot in the leg! >> coming up -- >> somebody in the park, what, armed and dangerous? >> yes. >> a shooter on the loose. and the prime suspect? >> all i heard was, open up,

police. they had two officers with guns drawn. >> pointing at you? >> yes. >> when dateline continues. uses fewer medicines to help keep you undetectable than dovato. detect this: most hiv pills contain 3 or 4 medicines. dovato is as effective with just 2. if you have hepatitis b, don't stop dovato without talking to your doctor. don't take dovato if you're allergic to its ingredients or taking dofetilide. this can cause serious or life-threatening side effects. if you have a rash or allergic reaction symptoms, stop dovato and get medical help right away. serious or life-threatening lactic acid buildup and liver problems can occur. tell your doctor if you have kidney or liver problems, or if you are pregnant, breastfeeding, or considering pregnancy. dovato may harm an unborn baby. most common side effects are headache, nausea, diarrhea, trouble sleeping, tiredness, and anxiety. detect this: i stay undetectable with fewer medicines. ask your doctor about switching to dovato.

nearby? >> i don't think so, they took off running. >> do you know if it was a male or a female? >> female. >> it was dark when the council bluffs pd rolled out to big lake park and found a wounded and beaten liz golyar. they patched her off to the hospital, while caught -- helicopter ground with -- >> somebody on in the park, or on foot, and dangerous. >> yes. >> while other cops searched for the shooter, detective matt lee cool and checked on liz in the hospital. >> but liz was lucky. the bullet went clean through her like, missed bones and arteries and that could've been much worse. she told a detective what happened. >> she says she came out here to clear her mind, and she walked out to a bench and sat

down. and then a female, who she believed to be amy flora, came up behind her, put a gun to her back, told her to get on the ground, and shot her in the leg, and then ran off. >> a few minutes later, a city police task force surrounded amy's apartment. >> i kind of saw somebody leaning against my building. and i said, who's there? and all i heard was, open up, police. so, i opened the door. and they had to officers with guns drawn. >> pointing at you? >> yes, yeah. >> what do they say to you? >> they had said that i was accused of shooting liz. >> they searched her home, and later sat her down in an interview room and hooked her up to a polygraph machine, asked her questions like this one, among others. did you go to big lakes park that day? >> no. >> amy also denied that she shot liz, again and again. but she failed the polygraph. still, something did not add

up. when that local detective arrived at amy's place right after the shooting, he felt the hood of her car, ice-cold, had not been driven for a while. and the neighbors said amy was home all afternoon. so, was amy so nervous she blew the polygraph? or was something else going on? detective avis went to see liz at the hospital, his recorder rolling. >> i feel like it's just writing on the wall, what it is. it's amy shot you with dave's gun, isn't it? >> pretty much. that's what i'm thinking. >> dave still does not think so. >> seemed like the friendly cop. >> or the dumb one. i'll be whatever she wanted, as long as she kept telling us information. >> wait, what? avis was playing dumb, he said, to pump liz for information, because he and his partner had a strong suspicion about who really shot her. a truly shocking idea, something beyond devious.

>> she shot herself was what i thought. >> liz shot herself? that's sounded crazy, or maybe a certain kind of crazy. remember, to help catch cari farver, liz had given the police cell phone. and here's what detectives doty and avis found on that phone. a photo of cari farver's suv, which did not make any sense at all, because -- >> we looked at the date that was taken. and it was taken on christmas eve, 2012. >> was that not when her car was actually missing? >> yeah, it had not been recovered until january 2013. >> so we thought, that's weird the police could not find, it dave did not know where it was, but somehow liz was able to take a picture of it. >> that was not all. remember that threatening photo cari emailed to dave, of a woman bound and duct taped? that photo was linked back to

liz, which made them wonder, was it possible those wild and scary electronic messages all sent in cari's name were really sent by liz? tricky, even for a computer whiz to nail that bit of jell-o to the wall. >> it is beyond our expertise, and it's when you gotta say -- >> how well you know computers, social media, that nonsense? >> made us want to pick up a phone, call tony carver, and ask if he has any more information? >> by day, i do information work and i do that for years. and by night, i fight crime. >> [laughs] , you sound like a superhero. >> anthony carva's day job was i. t. for pottawattamie county. but by night, he's a reserve

avis busy themself with good old-fashioned earthbound evidence. remember that one unidentified fingerprint found in a mint container in cari's otherwise spotless suv? >> we asked our crime scene tech we compare that fingerprint to a known fingerprint of liz, see what you came up with? >> it was a match. >> this lady who should've had very little interaction with cari should have no reason to be in her vehicle. >> only matter in passing, one time. but now, her fingerprint is in her car. >> liz in cari's suv, liz impersonating cari online. there was no logical explanation for it, unless -- >> we think liz may have been involved with making cari disappear. >> a case about to dive right through the looking glass. and on the other side? hard to believe. coming up --

>> by the time these two county detectives started looking into the strange case of cari farver and all those jealousy fueled texts and emails and threats of arson, cari's son max was getting ready for high school graduation. he had not seen his mom in three years. but, always the optimist, he decided to try one more time to reach her on facebook. >> i was, at that point, just a last-ditch effort hoping something would happen. >> if this is really you, please come back. i want you to be at my graduation. >> when she didn't respond, how did that feel? >> i was not really surprised. because, like i said, i knew that it was not her. >> max and nancy has suspected for months that all those digital rants were not actually from cari. they didn't know it yet, but detectives jim doty and ryan avis agreed with them.

the detectives already had proof liz was impersonating cari online. but they also suspected something much darker. remember another part of their investigation room ball of this basic question, was cari farver alive or dead? >> her father died, and she didn't go to the funeral. and she missed her son's birthday. all these things. it did not take ryan very long at all to come up with adead end, he could not find anything to show that she was alive. >> suddenly, cari farver looked not like a villain, but like the real victim. and the woman who claimed she was the victim, liz golyar, looked like the prime suspect in cari's disappearance. >> because why else would you disguise yourself as cari, if you weren't responsible for her? why would you be in cari's if you weren't responsible for it? >> all that is so counterintuitive and so bizarre that, you know, it wouldn't be

expected to believe such a thing. it was stunning, really. liz, apparently impersonating cari for years, sending thousands of texts and emails in her name. but now they had a bigger question, and a much bigger problem. >> i guess part of the worry was, even if we could prove that it's liz sending all this stuff out as cari, well, that doesn't prove murder. >> murder? yes. sergeant doty and corporal avis believe liz killed cari out of jealousy. impersonated cari to win back dave, and frame his ex partner amy for everything, even going so far as to set her house was on fire, kill the family pets, and shoot herself in the leg. pretty wild stuff, but could they prove it? >> we need something more, so we weren't quite sure how to get to that point. >> and then, liz herself, by

accusing amy of shooting her, gave them their big idea. >> and that's when we introduced jim to liz. >> i'm investigator doty, i work for the sheriff's office. >> a week after the shooting in the park, liz arrived at the sheriff's station, wearing her work uniform. >> i told you i was looking into a missing persons case briefly on the phone. >> he told her there was a break in the case. >> there have been some remains that were located. >> it was a ruse, of course. >> we are waiting on the lab results to make a positive i. d., but the initial indication is these remains are cari's. >> okay, good. >> meanwhile, said detective doty, he was hoping liz could help establish a timeline, like, when was last time liz saw cari. that was easy, liz said. one brief encounter when cari went unnannounced to dave's apartment in 2012. >> i don't know he was dating

anyone else at the time. so, she came out, and i was going in. and she made a smart comment to me. >> why did she say? >> she called me a bitch. >> okay. >> it was not a big deal at the time. i just want to get my stuff. >> that is the only time you ever seen her in person? >> she told detective doty that it was dave that blamed cari for all the harassing messages over the years. but, just as she told detective avis, she now thought that amy was really the one behind it all. >> she was with him for 12 years. and she still goes in and out of his life at all. >> so you think she's the person that did some of the stuff to you. >> i'm just saying as another person who would be possessive of dave, it would be her. so, i would not put it past her. >> detective doty pretended to agree. >> i'm thinking, if she was bold enough to go, and shoot you.

she could easily be bold enough to do something to cari. >> of course he said, he would need to prove it. >> if we had messages from her saying hey, i did this or i did that. angle i could easily start building that case. >> we want to build a case against amy. we want to get amy thrown in prison. which, we were hoping was music to her ears. >> and apparently, it was. liz agreed to help with the investigation, and she limped away. >> and she became a little deputy for you? >> yeah. >> no telling what liz might come up with next. coming up -- liz forwards emails and propels the investigation. >> when they first heard coming in, they were pretty vague. >> so you want me to try an email her back? >> and that's -- i'm leaving that in your court, liz. i mean, if that's something you would feel okay doing, that would be really helpful for us. >> and detectives give dave a

days, liz began forwarding them emails from amy, she said. although the misspellings looked awfully familiar. >> i shot you liz, to make sure dave stayed away from you. i made a couple of those fake emails and numbers you and dave thought were cari to get rid of you, liz. didn't work too well. >> when they first start coming in, they were pretty vague. >> so, detective doty spoke to liz again. they needed more, he told her. >> so, you guys want me to try and email her back? >> and that's -- i'm leaving that in your court, liz. i mean, if that's something you would feel okay doing, that would be really helpful for us. >> liz said she would try. >> cari's family, some closure would be nice, i guess. >> yeah, that is true. give her family some closure. >> so, she sent this email to amy. >> so, if you really shot me, then what kind of gun was it? so, did you ever get to meet up with dave's ex, cari? according to liz, amy responded.

the gun was dave's that i used. don't worry, you didn't get it as bad as crazy cari. then, she wrote this. so when i met crazy cari, she would not stop talking about dave and him being her husband. she tried to attack me, but i attacked her with a knife. i stabbed her 3 to 4 times in the chest and stomach area. i then took her out and burned her. i stuffed her body in a garbage bag with crap. the sort of a detail a killer would know. to see while working on it must of been enormously exciting. >> it felt good. >> a couple of days later, dave kroupa called detective avis, to say he'd just had a disturbing conversation with liz. >> she told me that the sheriffs had found remains, like, somebody is dead. and that they thought that it was this cari. and that supposedly they had

all this evidence against amy. you know, that she's complicit, or knows something, or whatever. i don't know. >> dave was understandably shaken up. avis could not tell him much, but he did drop a big hint. >> i'd be damn near moved in with amy if i were you. >> okay. >> since liz did come and tell you this, i would avoid her like the plague right now. >> dave took his advice, moved in with amy, so they could protect each other and their kids. but that outraged liz. she called the police to say so. >> looks like the only person that benefited was her. so she gets to shoot somebody, and then she gets to kill another person. and then she has to move in with dave, and she gets to be free. and you guys aren't arresting her. >> detective doty told her he still needed more evidence. so liz gave them access to her email account. and over the next month, emails came pouring in. allegedly from amy, of course. i got hold of cari, and we

convinced that lives gallagher killed carry in that convoluted plot to win back her ex boyfriend, dave. she had handed them emails describing the murder, details only the killer would know. the murderer, she said, was dave's wife amy. investigators thought otherwise, and needed to look in cari's car again. but the car had long since been sold to somebody else. but they found it, much used, in a whole other county. >> took off the passenger seat, pulled up the fabric of that, and there was a dark red state right on that seat, large stain. >> they tested it, human blood. dna confirmed it was cari's blood. >> that's huge. >> it was. but we did not know what to do next, for sure. >> but they were sure they had to move fast, because it appeared liz was scouting a new target.

>> we would see her circling amy's apartment, multiple times a day. >> because doty and avis believed cari was murdered in omaha, they asked the city police for help. and the omaha pd picked up liz on an unrelated misdemeanor crime. but in the interview, their questions were about cari. liz stuck to her story that she was the victim in this tragic tale. >> what do you think happened to cari farver? >> i don't know. i don't know if what amy's saying is true. i do not know. i'm more scared that something is going to happen to me, and then my kids won't have anybody. >> the omaha detective added some pressure. why, he asked, was her fingerprint in cari's car? >> i don't know. but i've never even been in her car. i don't even know what's car she drives. >> she denied everything.

>> you are just going to lie to me. >> i'm done talking. and i'm going to have my attorney. because i did not do anything. >> at the end of the night, she bonded out and the county attorney wanted more time to review the evidence. >> what was it like, waiting for that? was it frustrating? >> it was. >> months went by. max, who had not heard about any of that recent investigation, graduated from high school without his mom. >> that was a real, kind of, stake in the heart. but -- because -- >> god knows if there's any indication she was going to attend, it certainly would be have been your graduation. >> yeah. >> summer came and went, another winter set in, and then, december 22nd, 2016, four years after cari farver vanished, after reviewing all the evidence, the county attorney finally felt there was enough.

liz golyar was arrested for murder. >> the best part of it was being able to go to nancy and tell her, we have arrested somebody for the murder of your daughter. >> that was a big day for her. >> that was what made working this whole case worth it. >> feel like driving out there this year. >> could not drive fast enough. >> it was big news for dave, too. >> that was the first time i could go outside and take a breath of fresh air and say i don't have someone over my shoulder today. >> liz sat in jail, while the prosecutors prepare for a trial they knew would not be easy. no body cases are tough? >> circumstantial, it was very circumstantial. >> then, as the trial date was bearing down, a teeny, tiny memory card yielded an amazing discovery. >> it was just basically bs luck that you got that, right, last minute? >> i don't think it's luck, just divine intervention.

>> coming up, a signature tattoo, the ultimate computer clue -- >> it turns up on a picture -- >> of a dead body? >> yeah. >> holy cow. >> would cari farver get justice at last? >> it was nerve-racking. >> when dateline continues.

>> this is a bizarre and twisted case of failed action. >> nevertheless, on may 10th, 2017, they put liz golyar on trial, for the murder of cari farver. >> it is a vote on obsessive woman that would stop at nothing to get what she wanted. >> liz waved her right to a jury trial. a judge would hear the evidence. the prosecutors laid it out methodically. cari's blood in the car, liz is blood on the mint container on the main container, the emails, the vast probe of digital forensics. they even tracked down a purchase on cari's bank card after she vanished, a walmart receipt. >> one of the items was a shower curtain. and the shower can was familiar to us because, in that phone than we did in 2013 of liz's phone, there was a picture of that shower curtain. >> and they found the shower curtain itself at lewis's apartment. there was also a photo of cari 's drivers license with a large knife next to it, email today. he thought it was a threat from cari.

in fact, it was sent from an email account created by liz. >> all these pieces together made a big difference. >> all of it, put together, the prosecutors told the story said it told the story of how liz golyar murdered cari farver. they told the judge it have in the morning on november 13th, 2012, after dave kroupa left for work. cari was on her laptop. >> we know from examination of cari farver's known facebook that she logged into her facebook at 6:39 am that morning. >> about two minutes later, she logged off. she was supposed to be going to work, but never made it. >> she was intercepted. something happened. that something was the defendant. >> hard to know exactly what liz did to cari, but -- >> it did not take her too long. because at 9:54 am, cari farver's cell phone is being used to access facebook.

>> at that moment, it appeared cari unfounded dave. >> the fact that she had facebook friends, the actor temerity, one of the first acts she takes is to eliminate that facebook friendship. >> from then on, in cyberspace, liz became cari. >> all from that purpose, for the reason of convincing people her friends, her family, relatives, everyone, that she was still alive. >> nancy went to court every day for the trial. heard the details for the very first time. >> when i heard all of this, what this person was doing in her name, it just made me so angry. because, cari did not deserve that, at all. >> so, strong case? the prosecutors hope so, though, nobody cases are tough to prove. but, was it lock, divine intervention?

before the trial began, detective avis and tech grew carva went back to dave kroupa, and asked if he had anything that might help them? and that's when it hit him, he put a tablet into storage and had forgotten all about it. so he fished it out, and carva examined it. >> tony remove the external sd card, out of memory, that had been deleted and reformatted. >> blank, or so it seemed, until carva took a closer look. peter. >> there were, i want to say, thousands of pictures that he was able to locate. >> thousands of photos that liz thought she had to leave it. >> one of the pictures that we found was a chinese symbol, that we were able to determine met mother. and there were dark lines in the picture. >> dark lines?

they look more closely. those lines were veins, and what looked like someone's foot, someone's deceased foot. avis called cari's mom nancy. >> nancy was able to email a few pictures, and sure enough, cari had that same tattoo on her left foot. >> wow. >> identical. >> and remember the yin yang tattoo mansion in one of those possibly confessional emails? >> all the sudden, it turns up in a picture -- >> of a dead body? >> yeah. >> holy cow. that was cari's too. the tattoo parlor kept a record. >> my first thought when i saw those photographs is that this defendant took a trophy, or trophies, of the person she killed. >> the motive, an old one, jealousy. >> it was all because of dave kroupa, she did it because she wanted this man. >> jealousy can make you do strange things, but that's just

-- why so much? why? >> i think it snowballed. when she did it, she could not stop. she had to make cari look like she was still alive to get the heat off of her. and it just went on and on and on for years. >> dave kroupa heard it all, and finally understood. >> i mean, it makes sense now, at the end. but, you know, the tarantino movie always make sense of the end. you know, it does not make any sense getting there. >> and liz is a defense attorney, james martin davis, a greek. it was a movie. a fictional one. >> i know they have all this bizarre behavior, and have all this circumstantial evidence, but he does not show my client on that day in this jurisdiction -- and stabbed cari farver to death. >> without that, no murder case. >> you may have camcorders, and you may have smart cards, and you may have phones. but you do not have a body.

and you do not have a cause of death from a medical examiner. what we have is their belief, their speculation, their notion, that this is what happens. but that cannot convict. >> and then the judge retired to think about it. and returned to an anxious courtroom. max, inside the courtroom, waited for the words. >> it was nerve-racking. >> and then finally, an answer. >> the court finds the judge, the defendant is guilty. >> guilty of first degree murder for killing cari farver, that second-degree arson for setting fire to her own house and killing her pets. she was sentenced to life in prison. just a few rows behind liz, cari's mother nancy finally heard the long forwards from the judge. >> saying that cari did not vanish off the face of the earth and she did not just vanish into thin air. it was just totally relief to me, and i just started crying.

>> you can't grieve, really, until you know. and now they did. >> it will never go away. but, at least we can deal with it now. have to deal with it. >> so important, said nancy, to finally set the record straight about a loving mother and a good woman who never abandoned anyone. >> and i think it would've been important to cari too, because she would have wanted people to say, this was not me. >> max followed his mother's footsteps, pursuing a career in software engineering. >> yeah, she was the one that really got me to understand computers. i will never type as well as she could. but, she is definitely a big

influence there. >> she inspired your -- >> yes, she definitely did. but, -- i have her to think for the road i'm going down now. >> i think should be pretty proud of you. >> i hope so. >> it was like being in a nightmare. my mom was never late. that's what it mesa point manse. not just disappear. >> a mother of two, disappears. >> she waved the quick, i walk down the stairs, out the door. >> but she was not the first to banish, this was a town that appears to be haunted by a serial killer. >> it became sickening to hear that another girl got
