exclusive deposition tapes. >> tell us your name, please sir. >> ethan couch. >> tonya-cocoh. >> frederick anthony couch. >> reporter: did they shower him with everything except the word "no"? a case of affluenza. it set off a national fire storm in a case settled just last week. affluenza. >> outrage not just at the teenagag, but a mother and ther as well. decide for yourselves, when you hear from them under oath, for the first time ever. here's matt gutman. >> reporter: take i-35 20 miles south of ft. worth and you arrive in burleson, texas, a land of big houses and big trucks. what kind of people live here? >> probably just a good, average, middle-class,

hard-working folks who get up every morning and go t twork. >> reporter: it was the night before father's s y and eric boyles wasaspending it with his wife hollie and daughter shelby. >> shelby and hollie really called out and said, "eric, come here." when i walked through the door, they were standing at the window, to the front. >> reporter: out in front of the house a young woman driving of a white suv had spun out and was now standing by her disabled car. >> so the girls headed out the front door. >> reporter: the driver of the suv called for help while shelby and hollie waited with her. that same night, down the road from the boyles' house, lucas mcconnell's family was hososng a party organized by their youth pastor, brian jennings. >> he was one, the closest people that i had who wasn't family. i was around him all the time. >> reporter: around 11:00 p.m. with the party winding down brian needed to return some tables and chairs to his church. lucas and a friend jump into the back of brian's white truck and they head down the road that would take them right past the boyles' house. >> i remember we saw a car on the right-hand side of the road, and he decides to pull over. >> reporter: it was that

disabled car alolo with holly and shelby bles standing on the road with the driver. >> we are trying to get out of the car, and he tells us, he is like, "no, y'all just -- y'all sit tight, i'll be back in just a minute." >> reporter: with brian jennings on the scene, there are now four people by the side of the road. meanwhile, a third location just a few houses down, there's another party in progress. but this one's not so innocent 16-year-old ethan couch is there with seven friends. >> they're drinking, they're having a good time, and then the young woman, um, needs to go to the convenience store. so they decide, well, we'll go get them. >> reporter: all of them? >> all of them decide to go. >> reporter: eight teenagers load into ethan's souped-up, fire engine red pick-up. six in the cab, two in the flatbed, and head out onto the road. ethan guns it, hitting nearly 70 miles an hour in seconds, his truck barreling toward the scene at the boyles family mailbox. ance is bringing together a crowd of people whose lives are

about to violently collide. eric boyles is inside when his world changes forever. >> i felt, "wait, you know, we don't live in california, but you would almost think, you would almost think you just had thquake." i mean, the house shook. >> reporter: when that red pick-up truck packed with eight teenagers, two in the flatbed, lost control, it swerved into a ditch, sideswiping that didibled white suv, then mowed down those four bystanders. crashing into brian jennings' white truck before flipping over into a tree. these photos show what remains of the ford f-350 that ethan turned into a weapon of mass destruction and brian jennings' white chevy tossed across the road. the bodies had been scattered hundreds of feet. at the moment of impact, lucas mcconnell was seated in the back of brian jennings' parked white truck. do you remember the sound of metal crunching, of glass breaking? >> glass breaking, and tires screeching. the car that we were in got hit,

and we got shot across the road, and we nailed a tree. the back window was completely shattered. and a lot of that glass was in the back of our heads. >> reporter: just seconds later, lucas' father kevin, part of a caravan coming back from that party, pulls up on the scene. >> i see taillights up ahead, as i got a little closer, i see debris in the road and i'm thinking, that's not a party, that's a wreck. the debris in the road that i saw was the chairs that we had been taking back to the church and my heart just sank. i was like, oh, my god. >> reporter: eric boyles is in his house when he feels the explosion, rushes out his front door to where he left his wife and daughter. he starts dialing the phone. >> was on the phone with 911. >> tarrant county 911. what is your emergency? >> there's a multicar accident t in front of my house. >> reporter: while eric's on with 911, a half dozen other frantic calls come in.

there's kids laying in ditches in the street. >> are you with the accident right now? >> oh, lord, oh yes. there's another child in the ditch. >> oh, my god. we've got one laying on the road unconscious. they say he's breathing. >> there were already people out there in front of the house. there was just debris everywhere. a table and chairs and car parts and everything else. i walked in the road, and the first thing i did was, i found there was a male laying in the road, wasn't moving at all. >> reporter: between the four people dead in the street, and the teninjured in the vehicles the casualty count is staggering. eric boyles was yelling for his wife hollie and daughter shelby. >> i am calling out hollie and shelby as i walk. and i kinda got halfway between the road and my fence. and that's when i found hollie. and when i found her, i mean, there was no doubt that, that she was gone. then it was a matter of "okay, so where is shelby?" >> reporter: as eric stumbles

daughter, about 20 feet down the road, he sees a young woman. her body thrown up against the fence. >> everything told me this should be shelby, it didn't look like shelby. and i am sitting there trying to process, the amount of trauma the bodies went through and, and what would the impact be. and what would that do to you? >> reporter: at the same time on that same dark road, kevin mcconnell is also searching for his friend, youth pastor brian jennings. >> on the other side of the road i see brian laying in the ditch. i ran over there. >> reporter: so, you're on the ground trying to tend to brian and suddenly hear what you think is the voice o oyour son from the truck. >> yes. i just heard his voice and it was just at that moment that i realized that lucas had been in that truck with brian. >> right as we got out, we realized that it wasn't just us. there was people everywhere and then we saw brian. >> i tried to feel for a pulse, i didn't feel a pulse. and i pull out my phone, i'm calling 911. >> sir, how many people are

do you know? >> one, two, three, multiple. >> multiple? >> i don't even know how many. >> my dad said, "just hold this fence right here, and just pray." >> reporter: you can hear lucas' terrified voice in the background on that call. >> i need you to sit here, and i need you to pray. >> oh, my god. >> come here. i need you to sit here and i need you guys to pray, okay? >> reporter: do you remember what you were praying for? >> for brian's safety. >> about that time is when the other cars from the party started getting there. >> reporter: brian's wife shaunna arrives on thihihellish scene.e. >> it was a normal drive. and then, all of a sudden, i saw teenagers walking down the side of the road and my first thought was, why do people let their teenagers walk down the side of the road? it's like almost midnight. >> reporter: shaunna pulls over and realizes there's been a crash and her husband was involved. >> i really thought, okay, he

that to me. >> r rorter: but her faithths tested by what she finds farther down the road. >> well i saw him and i knew that it wasn't good because i could see that kevin was, um, doing cpr. >> reporter: and by now shuanna's three children are also on the scene. >> i was just crying out to god. i was like, "please save my dad. i need him. you can't take him yet. i am not ready." >> the first emt or firefighters that got there, they were just so overwhelmed. >> they would just walk down the roro and, is he consciouou are they conscious? are they conscious? >> the scene was as bad if not worse than anything i've seen and that's 35 years of law enforcement. it was a huge crime scene spread over hundreds and hundreds of yards. >> tonight we're hearing the chaos in the moments after a truck full of teens -- >> slammed into three cars full of good samaritans said a woman

with a flat tire --- >> it's almost like tching a movie. it's like it's not happening to you. and it's just surreal and it's not, it's not real life. but it was. >> reporter: when we come back the 16-year-old who was behind the wheel of the red truck has left the scene. but does he really think he can just walk away? >> he was like, "yeah. you out of all this." >> reporter: stay with us.etty stuffy. when dad opens up the window, what's the first thing he does? the tobin ststce. but when we open up the w wdows, you can see the dust floatingnground. there's dog hair. pollen. more work.

"20/20." >> reporter: the carnage out on burleson retta road looked like a plane crash. four people killed instantly, over 100 onlookers, first responders and victims' families, like eric boyles, jammininthe street. >> i have never beenenn the military, i have nevev experienced war, but i can appreciate what they go through. >> reporter: local news crews capture this footage. authorities scanning through the wreckage. they needed to find the person responsible for the crash. as it turns out, police wouldn't be the first to do that. what condition was he in? >> he was unconscious. >> reporter: corbin clark and his mother shana, two neighbors heading to the scenenefind a passss-out teenager in a d dch a quarter mile down the road. >> and i kept saying, "hey, what's your name, what's your name?" he said, "what's your name?" and he said, "hey man, i am -- i am ethan. i can get you out of all of this." and i was like, i guess he thought i was involved. but he was like, "yeah. just remember my name, i can get

you out of all this." he kept saying that. >> reporter: his name -- ethan couch -- is now one everybody in burleson remembers. somehow he not only survived the crash, but managed to free himself from the mangled truck and,d,ather than help anyoyo, he walked away. >> the police came. and they said, "we need to get you in an ambulance." >> reporter: was he struggling with the officers? >> he kept shaking, trying to shake 'em off, saying "i don't need all this." >> once ethan couch was found, the story came together pretty quickly. >> reporter: that shocking story would turn sadness into outrage. get this -- ethan's a 16-year-old living the life of an adult, by himself, just seven n ors down from eric boyles. ethan was supposed to be cleaning the place up so it could be sold. where were his parents? well, fred and tonya couch had already moved on up to this sprawling place in ft. worth. a 7,000 square foot compound. take a look at that glittering

the couch money-maker. fred's got a multi million dollar sheet metal business, and this estate is complete with guard towers, guest house and a steel gate surrounding it. but the story of the crash begins to be told by ethan's blood alcohol content. it comes back three times the legal limit for an adult, and that's three hours after the crash. >> understand this is three hours of time he had for his body to clear alcohol out of his system. speculation, what his blood alcohol was at the time of the accident is through the roof. >> reporter: as ethan awakes in a hospital bed, the sun also rises over bururson retta road. it is father's day. >> and the next day, yeah, i find these packages, where my father's day cards had been filled out. and my father's day gifts were

there was no preparation, no titi to say good-byes. >> reporter: out in front of eric's house, investigators are still sifting through the crash site. wreckage that spans almost a city block. and seven doors down, officers pay a visit to ethan's burleson house. no one is home, but a trash bin brimming with cans and bottles right outside paints a vivid picture of the last night's activities. not only was he drunk, but there were traces of thc, valium, and some other drugs. >> right. which according to our toxicologist, um, were bad enough on their own. but you combine those with alcohol, just a recipe for disaster. >> reporter: richard alpert is an assistant district attorney who came onto the case just a day after the crash. >> the first thing we started doing is bringing those witnesses in and talking to 'em. >> will you please state your name. >> garrett ballard. >> starr teague. >> reporter: garrett ballard, ethan's best friend since grade school, and starr teague, a former and brief love interest,

were two of the teens in ethan's red truck thatatight. these are never before seen deposition tapes from a civil lawsuit resulting from the crash. starr says ethan, garrett and another boy started drinking around 6:00 p.m. the night of the crash. >> all three of them did a shot of vanilla -- i don't, i don't know what it was. >> so they start drinking, taking some shots, and then they decide to go pick up some friends. on the way back they decide we want to get some beer. so there's alreadydylcohol at the house ananethan clearly has money, but they decide it would be more fun to steal the beer. >> at the walmart, i went in. grabbed the beer. >> reporter: this is surveillance video from that walmart. sure enough, there's garrett ballard and four other teenage boys. >> and then we walked out the fire exit. >> ethan stayed with the vehicle. and when the other five stole the case of beer, they actually ran out the exit door. >> reporter: the teens head back

drinking contities. not t st beer, but shots o othe 190-proof grain alcohol called everclear. >> and then the young woman, um, needs to go to the convenience store. but even the other ones who'd been drinking knew ethan had too much to drink and they tried to talk him out of it. and he would have none of it, just made him angry. >> reporter: with that, all eight teenagers pile into the truck, with ethan couch behind the wheel. right away, things start breaking bad. >> pulls out of there and immediately is going so fast that they're, starr is telling him to slow down. and so his response is, well, i'll just drive into oncoming traffic, so he starts playing chicken with the car in front of him. >> i was yelling at him. get over, get over, you need to get over. and when he swerved, the back tires jerked. >> just remember seeing something in the road and then

being in the air.. >> the vehicle was going about 68 miles per hour. >> reporter: had ethan ever pumped the brakes? >> no brakes. >> reporter: never touched the brakes? >> no evidence of braking was there. when you're that intoxicated doesn't work the way it should. >> at that point, i thought that ethan was dead. i i eaked out and, uh, i iot out of the truck, i climbed out thth back and i guess i had tunnel sion, i just walked, i just took off. >> reporter: but for ethan couch, walking away from the consequences of this accident wouldn't be as easy. not with this prosecutor determined to hold him accountable. >> i don't know if ethan's life is salvageable and quite frankly, i don't care. >> reporter: but this guys about to give him the shock of his career. >> i believe ethan couch is suffering from --

we return to "20/20"'s a >> reporter: more than 1,000 people gathered in burleson to remember a youth pastor killed on a tarrant county road last week. >> i'm going to live to make my daddy proud. >> reporter: the memorial for local youth pastor brian jenningsgsrew so many mournersrs it had to be streamed online. while crowds were mourning in texas, ethan was in a west coast resort town. >> ethan was at a spa-like treatment center in california. >> reporter: welcome to newport academy. its promotional video shows sunsets around the firepit, equine therapy and yoga. rehab that cost ethan's dad nearly $100,000. >> we're talking aboututim living in n xury even while he's being treated. >> reporter: ethan's parents, meanwhile, were trying to figure out how to keep their kid out of prison.

they quickly assembled the best criminal defense team money could buy. and what a memorable defense it turned out to be. >> when did you first see ethan couch? >> it was about two hours after he got home from the hospital. >> reporter: this is dr. dick miller in another deposition video. now, he's s prominent psycyclogist hired as part of that powerhohoe legal team. >> well, i think ethan couch is suffering from adjustment reaction to adolescence, i would say. >> reporter: what dr. miller was learning in his meetings with ethan would come to shape this story, that throughout his young life ethan's parents showered him with everything, except responsible parenting. >> ethan learned you should be able to do what you want to do when you want to do it. >> i think that was the message generally. >> before too long we realized thth we weren't dealing with a typical l venile. >> reporter: or typical parents. the couches had plenty of

every day was christmas. nintendos and jet skis as a kid, later that tricked out truck and his own credit card. >> instead of the golden rule. he was taught that we make the rules at the couch household. >> reportete those rules cluded traffic laws. for ethan there e ren't many. hihiparents happily handndg over the keys of their trucks to their 13-year-old. something that, at the time, caught the attention of one of ethan's teachers. >> and what did she say? >> mrs. anderson said he's not allowed to drive to school. >> and what was fred's response? >> something to the effect that, i'll buy the school or something along that line. impulsive. >> and when he didn't buy the school, he pulled ethan out of the school. >> yes, he did. >> reporter: after that, ethan's parents opted for home-schooling. it's not clear how much schooling he actually got, but

he definitely got the home. as in the 4,000 square foot ranch house he frequently stayed at just down the street from the boyles family. these pictures from the website zillow show a wet bar in the den and a swimming pool out back. and if his parents weren't around, it sure seems that alcohol often was. >> from the friends s talked to, ththone thing they admitted very early on was that ethan was no stranger to alclcol. >> i t tnk one night we wentnt through a 30-pack just between us. >> roughly 15 beers apiece. >> probably about that. >> reporter: ethan's buddy garrett even admits to seeing him drive drunk on at least three different occasions. there was history there. >> there absolutely was history. there was history and warning after warning that this was gonna happen. >> reporter: for prosecutor alpert, enough was enough. it was time for young ethan to get a dose of reality. >> up p that point life has just told him you can get away with it. we were gonna make sure he didn't get away with this. >> reporter: and he charged ethan with everything he could including four counts of intoxication manslaughter.

alpert wanted the poor little rich kid to do some serious time. >> we were hoping for and asked for 20 years. >> reporter: when ethan couch loped into court, the selfie swagger from facebook had been replaced by this. brian jennings' daughter abby couldn't believe it. >> they made him look really innocent for the trial. and that's not who he was. >> reporter: but it turned out there would be no trial. ethan couch admitted guilt and the proceedings moved directly to a sentencing hearing. >> he really didn't look at anybody. he just kind of sat there. basically stared off into space. >> reporter: and now we come to the key moment in the case. while recommending treatment over incarceration, dr. miller drops a curious rm which goes off like a bomb, affluluza. >> he got up there and he talked about the fact that the reason for this crime was, he was a child of privilege and his parents didn't say no to him.

>> reporter: when you heard it what did you think? >> i smiled. i mean, it was ridiculous. >> i looked at my mom, and she just kinda gave a look. it seemed like a made-up word. >> we all agreed he had terrible parents. but at some point, offering up that because he was raised as a rich kid and he didn't know the difference between right and wrong as a rult of affluenza, just kind of blew our mind. >> repter: and they were i for an even bigger shock when judge jean boyd announced her ruling. ethan couch was sentenced to ten years' probation and time in a rehab facility. four dead, nine injured and not a single day behind bars. wfaa reporter jim douglass covered the case. at was the reaction? >> volcanic. mainly aimed at judge jean boyd, longtime juvenile court judge here. >> she really never even got through with her sentencing.

out pretty quick. >> i felt like the judge spit in my face. >> reporter: the media crushed to get a shot of the boy who cried affluenza. >> to me it's not right. >> he'll be feeling the hand of god. >> money always seems to keep ethan out of trouble. reporter: ethan's lawyer had a different take. >> we applaud judge boyd for having the courage to issue this sentence that's going to give ethan couch a chance. >eporter: the affluenen defefee and judge's sentence lit the nation media on fire. >> too rich for jail! >> judge jean boyd said the teen wouldn't get the therapy he needed in jail. >> i am sickened by this judge! >> people wanted this judge's head. they just felt like there have never been consequences in this kids life and here's one more example. no consequences.

>> reporter: judge boyd wasn't the only one in the public's crosshairs. so was dr. miller, who took to cnn to defend himself. >> this kid has about an 80% chance of becoming a full functioning citizen. if he goes t tthe jail he has about a 10% chance. >> i mean, he killed four people. you can call it affluenza. >> i wish i hadn't used that term, everyone seems to have hooked onto it. >> what he didn't anticipate was that the b.s. of what his opinion was gonna be, hit the winds and he was gonna get the reaction he got, which he deserved to get. >> reporter: so many people were now asking did ethan couch's affluence actually buy him a slap on the wrist? maybe and maybe not, bececse for one family, ththcase was far from over. not so fast. this is not the end of this. >> reporter: they were about to force the couches onto the hot seat to answer tough questions under oath. >> when's the last time you recall disciplining ethan for anything? >> reporter: you're gonna want to hear this.

their day in court. >> and i thought, not so fast. this is not the end of this. >> reporter: so when your parents told you that they decided to go whrough with an actual court case, what did you tell them? >> i was ready for that. >> reporter: a lot of people were ready to hear something they'd never heard before -- the boy and his parents at the centererf this story speak.. tell us your name, please, sir. >> ethan couch. >> tonya couch. >> frederick anthony couch. >> reporter: it fell to lawyers greg coontz and todd clement to extract the peculiamily history that shaped young ethan's life. his parents seem like, you know, regular old texas parents in some ways. >> there's nothing regular about the couches. >> reporter: fred couch, a rags to riches millionaire, has his

owowhistory with the law. and get a loadadf what he alalgedly said during a a 1992 stop for a dui. >> did you tell the arresting officer, i make more in a day than you make in a year? >> probably. >> reporter: fred and tonya had an on-again/off-again marriage. the second for them both, the kind of fractured family life which might require extra care for an only child entering adolescecee. instead, these lawyers say, the couches let etn fast-forward into adulthood. >> people don't allow their kids to drive at 13. >> you understood, if he was at any time he was under 16, he was never to be driving by himself >> yes. >> nevertheless, you allowed that behavior to happen, correct? >> yes. >> i just kept asking because i wanted to.

the corner store by myself. >> and then that progressed to school? >> yes. >> reporter: fred couch admitted allowing ethan to drive but both parents say they didn't know about his regular drinking. >> have you ever seen ethan drink as we sit here today? >> i don't remember ever seeing him drink. >> reporter: maybe not. but she definitely saw him drunk. just four months before the fatal crash, 15-year-old ethan was stopped by police at 1:00 a.m. relieving himself in a parking lot. >> ft. woror officer comes upon n him, he's takingng pee outside of a truck, there's a half-naked 14-year-old girl passed out drunk and this 15-year-old kid is just mouthing off to this officer, using profanity, his mother shows up, starts talking to him. so she clearly knew he was out there. >> did you ask him where h hgot the alcohohoand the vodka that was in the truck? >> no, i shoululhave but i did not. >> why didn't you ask him where

he got it, to try to stop it from happening again? >> i don't know. >> reporter: these attorneys say ethan couch, who wasn't even old enough to drive was violating as many five laws that night. >ive violations of ththlaw and nothing's done by tonya. >> reporter: well, not quite nothing. tonya does admit to concocting a story with ethan to keep her husband in the dark about the more criminal details. >> i wasn't sure how he would react so i didn't tell him the whole truth. >> tonya told me that ethan was peeing at the dollar general. >> what action did you take? >> ethan walked back and forth to work for a month. >> reporter: oh, really? >> do you remember any occasion where your dad punished you by making you walk to work? >> no. i don't remember ever having to walk to work. >> repter: ethan was required to complete an alcohol awareness course and eight hours of

community service within 90 days. guess what. it didn't happen. >> we didn't do the community service. >> y y understood, did yououot, that he was likely to continue the drinking and driving if there weren't consequences? >> i should have known that, yes. i really didn't think that that would happen again. >> i just told her that i was nervous that he might be drinking being at that house by >> how long prior to the crash was that told to her by you? >> a week. >> reporter: and that same week ethan's friend starr teague says tonya witnessed ethan in the house with an open beer. whether tonya saw y'all with beer sitting there? >> she saw us. tonya wanted to come in and say, i was always really against drinking and driving but then enforce that?

disciplining ethan for anything? >> sometimes i would take little things away from him or we would just discuss the problems. >> when's the last time you recall disciplining ethan for ananhing? >> i don't remember. >> reporter: of course, it's hard to discipline a kid when he isn't always under the same roof. remember, the couches were letting ethan play grownup by himself in the burleson house. >> in your mind, it was okay to let a 16-year-old d stay at the burleson retta house by himself without anyone present, correct? >> that 16-year-old kid, however foolish that it may have been, he seemed pretty responsible. >> was there always alcohol then when you were at the burleson location? >> not always, no. >> most of the time? >> most of the time, yes. >> if there was alcohol, most of the time there was drugs as well?

list of drugs shocking for anyone, much less a 16-year-old. >> i've taken valium, drocodone, marijuananacocaine, xanax. i think i tried ecstasy once. pretty sure that was it. >> reporter: which brings us back to that deadly june night. >> and what was your plan? >> i was gonna have a couple people over and drink. >> do you recaca any sort of text exchange with yououmom the night of this crash? >> yes. she had just sent me a text like, don't be out late and don't drink and don't be drinking and driving. >> she was asking what we were all doing and he was telling her, she wasaselling she knew that we were drinkinin she was like, well, just don't drink and drive. >> reporter: that was certainly thoughtful but by now ethan had years of experience blowing off the rules without facing

consequences. why should tonight be any different? >> do you remember pulling out of the driveway? >> not really, i have like a, little like, a picture i imy head of just like turning out of the driveway but that's it. >> what's the next thing you recall? >> waking up handcuffed to the, the hospital bed. >> reporter: and after all this ethan's father actually distances himself from the "affluenza" defense he paid for. >> i don't even know that i believe affluenza is real. >> reporter: and despitetell the terrible media coverage, even being branded "the worst parents ever," fred defends his family. >> i don't think we're profoundly dysfunctional. >> did you teach ethan that wealth bought privilege? >> i don't believe i ever intentionally tried to teach him thth. >> did you teach ethan that indeed because your family was

>> never. >> reporter: the mcconnells are eager for a civil jury to hear every word of this testimony. >> i feel like it needed to be done. >> reporter: why? >> because i haven't seen any puniniment. reporter: but the couches are as determined to avoid another court room as they are to avoid our cameras. mr. couch? stay with us. until i realized our body handles a lot. 1,100 meals a year... 730 rushed snacks... add 300 stressful decisions... no wonder r r digestive system sometimes acts up. so try activia! enjoying activia twice a day for 4 weeks may help reduce the frequency of bloating, gas, discomfort or rumbling. the best part, it tastes great! dannon [ female announcer ] take skincare to the next level with roc multi correxion 5 in 1. proven to hydrate dryness, illuminate dullness, lift s sging, diminish ththlook of dark spots, and smooth the appearance of wrinkles.

we return to "20/20"'s a case of affluenza. >> reporter: it's been nearly two and a half years since the june night when so many lives intersected on this road. and the victims' families, like eric boyles, who lost his wife and daughter right outside his house, remain convinced that this was an accident in name only. >> this was not an accident. this was not a good kid that just made a poor decision. this event was going to occur somewhere. it was just a matter of when and who it was going to affect.

justice has been an exercise in frustration. not just for them but also for prosecutor richard alpert. what would justice have looked like to you? >> justice would have been the system doing something to ethan that life hadn't done to him at that point, which is hold him accountable. >> reporter: did you ever think of prosecuting the parents? >> we did. we, if there was a way to do it, we would have done it. being a bad parent unfortunately is not a crime. >> reporter: as the one remaining civil case, the one brought by the mcconnell family, worked its way through the courts, the judge from the criminal case decided to call it quits. jean boyd, the judge who handed down that controversial sentence, retired last year. she declined our reqeqst for comment. >> she will always be defined, her career in the public mind will a aays be defined by thth case. >> reporter: thousands of cases, but affluenza's the one people will remember.

these days ethan back working at his dad sheet metal plant. we reached out to ethan and his parents but they had no comment so we headed back to texas to track him down ourselves. it was no easy task. we checked out the fancy ft. worth h use but no answer there. so we went t t family business. we've been staking out ethan and fred's business which is right across the way for about a week now. but they're not like regular people. they don't come to work at regular hours. they don't keep regular hours so it's been really hard finding them. when that steel gate slid open and ethan finally emerged, he clearly wasn't looking to talk. but if you take a closer look, that's himimright there. the good news, he's not driving. abiding by at least that part of his probation.

and just as the trial in the mcconnell case is about to begin another stroke of good fortune ethan lucas and his parents have had a changegef heart settling instead of moving g rward with a trtrl. the last time that we met, you were very serious about taking this all the way what happened? >> i think we've succeeded. at least a little bit. >> reporter: by showing the world those deposition videos, the mcconnells belive they're showing the couches for who they really are. >> by you guys coming here and focusing attention on this, we've achieved our goals of letting the world hear about this story. >> reporter: the cououes don't wantnto talk. we'll probably never hear their de of the story, or r ar them apologoge. >> i think when you have things that you want to hide, you tend to stay in the shadows. it's time to move on. my family has been through a lot. >> reporter: these days the mcconnells are teaching lucas to drive on the same roads ethan couch tore through. and eric boyles is still in his home, even though reminders of that hideous night are just

stay here? >> people have asked, how can you come back to the house? people may not understand this but there's probably a little bit of peace knowing where they were. this is where their last moments were. faith, family, and friends is the only thing that gets you through it. >> reporter: shaunna jennings, the widow of youth pastor brian jennings, believes her husband did not die in vain. his purpose, she says, could be to reach the very person who took his life. >> maybe this is a wake-up call or that somehow brian's life can show him a different life that he could have. >> reporter: for her the time for outrage has passed and the time for forgiveness has begun. >> it's a daday decision to rgive.

>> reporter: because it's so easy to hate, isn't it? >> it is. but that dsn't do anything except punish you. i can't live my life bitter or angry. mary gets her bounce on. wow vary, is lry mom from the neighboood here? look at them all. ...'judgie'. see? you are looking good! using bounce dryer sheets is paying off. your clothes have fewer wrinkles, and static cling... ...ain't bringing you down. oh! and look, it's that ms.brooke-thinks-she's-all-that- and-a-bag-of-chips. good thing you brought your a-game. your a-game. bounun, the 4 in 1 dryer s set. get your bounce on. in the outback, steak and lobster is back!
