shown up to work. gavin, in 18 years, had never, ever not shown up to work. >> reporter: now lisa very worried now went to the sheriffs station to report gavin missing and waited and waited. days later, gavin's family went on nbc 4 in los angeles to plead for help. >> i'm not going to stop until i find him. so please help me find him. >> you guys want to pick one of these streets. >> now i'm in panic mode. we got to do something. >> reporter: what did it feel like to be in that spot? >> oh, it was surreal. >> reporter: the smith family put together a $20,000 reward for any information leading to gavin's whereabouts. nothing turned up. i would think that every hour that went by, you would be more dire and darker for you, right? >> it's very dark. it's very, very dark. >> reporter: it wasn't just the family having dark thoughts. they don't normally call a couple seasoned homicide detectives to look into a missing person.

>> they do when there is some suspicious circumstances. >> reporter: and in this case, they called in sheriffs detectives. >> his phone was missing. there was no use of it. we checked his bank accounts from the time he was missing. we checked his medical insurance to see if he had checked into a hospital. that never showed any activity. he was completely dropped off the face of the earth. >> reporter: but then, out of nowhere, a sighting. hundreds of miles north of los angeles, a businessman visiting the central coast says he saw gavin smith and a beautiful woman at a cash only taco restaurant in morro bay. >> i happened to click on the link, saw the photo, and i said oh, boy. >> reporter: the waitress corroborated the story. >> he was sitting right here, she was sitting right there. >> reporter: his sister raced up the coast to the restaurant. >> i said, here's my brother's picture. did you see him? >> reporter: and? >> no.

welcome back to "dateline extra." gavin smith's family was distraught after the 57-year-old larger than life dad vanished. how could the hard-to-miss 6'6" hollywood executive disappear without a trace? detectives were about to discover hidden secrets, gavin had a troubled past. continuing our story, here's keith morrison. >> reporter: gavin smith, as just about anybody could see, was his family's golden boy. his sister tara grew up in his aura, idolize him.

he of all people should not just up and vanish. >> it didn't make sense to me. and so i just kept, no, it can't be. it can't be. i just kept hoping. i did everything i could. >> reporter: but even as she ran down leads herself, it seems to tara that lisa, her sister-in-law, gavin's wife, wasn't searching. so he disappeared and you couldn't give up on the possibly he's out there somewhere and lisa could. and i wondered whether there were ever dark nights in your soul, i wonder if she had something to do with this. >> it crossed our mind all the time, i mean, it just did, did i think she could ever be the one responsible, the physical -- no. but somehow it kept playing back, why won't you search?

why? the only way somebody doesn't look for you is if you already know definitively. >> reporter: yeah. >> they're no longer living. >> reporter: and you must have had a reason for knowing that. >> that's what i would assume. >> reporter: it turned out lisa did know something, just not what tara expected. there were secrets which lisa and gavin had. >> i was the love of gavin's life. he adored me. our family is exactly what he wanted to have. he just got lost. >> reporter: lost. it all started in the early '80s, even before she met gavin when he was a stunt man on the tv series "remington steele," he played a shooting victim, falling from a second story window. the stunt went wrong and he broke his back. >> he would take pain pills for his back. so usually percocet, something like that for pain. when that didn't work anymore,

he was prescribed oxycontin. and he was addicted to it. >> reporter: he went to a drug rehab center called the matrix institute here in the san fernando valley. >> he clearly stopped using. he was feeling healthier than he felt in years. >> reporter: but when detective john o'brien and tyla bay heard about his addiction, they had to consider a raft of new possibilities. >> he disappeared, maybe overdosed. didn't have any of those answers. >> driving all over the valley, we would have moments in the car where we looked at each other and said, i think this is a suicide and then an hour later, we'd interview somebody and something would happen and we'd go i think this was a murder and our feelings and our gut instincts were going different ways very early on very fast. >> reporter: that's got to be pretty unusual. >> it was very confusing. >> reporter: confusing to lisa, too. because here was another secret.

the smiths were under water on their mortgage on the verge of losing their home. >> we were in a horrible position financially. >> reporter: lisa discovered before he disappeared, gavin had been taking money from his retirement account and recklessly blowing through his six figure salary and there were other signs of strain in the family. in april, 2012, a month before gavin disappeared, his son evan wrote this message on twitter. thoughts and prayers out to my amazing mom and brothers, please. my dad decided to leave the family last night. real family sticks together. sister tara spoke with gavin at the time. >> he was struggling with losing what he had come to know and love for so many years and that was his family unit. and he didn't want to hurt those boys and that's what he kept saying.

i don't want to be without them. >> reporter: but as much as he loved his boys, detectives learned, gavin had been unfaithful to his wife, had been seeing a woman named melanie and now that gavin had disappeared without a trace -- >> we went to talk to her to see if she had any information. >> reporter: did she? >> no, their relationship had ended. she had not talked to him and she had no idea where he was at. >> reporter: but, though melanie was the reason gavin moved out of his house the month before he vanished, she was not his first affair. there had also been a woman named commandy. that relationship was years in the past, but phone records showed gavin called her on may 1st, the day before he disappeared. cops tracked her down, too. what did she tell you? >> she acknowledged the prior affair and said she had not been in contact for some time and they had been talking via

e-mail. >> reporter: that would explain the fact that he called her on the phone? >> yes. >> reporter: she says she hasn't heard from him since. last sighting a colleague saw him driving his black mercedes. >> we felt the vehicle was still out there somewhere. >> reporter: so find the car and maybe find out what happened to gavin. and nine months after gavin vanished, they finally got the break they were looking for. >> i said, i'm here to talk to you about your daughter and he started crying and he said, she saw everything. >> coming up -- >> we just waited till she showed up and surprised her. she was very nervous, startled. >> a new witness and a game changer of a clue. >> i kissed my partner on the cheek, it was pretty exciting. it was a big piece of evidence. >> huge moment. >> you think you can't be shocked but you can be. >> when "dark valley" continues. . ...this one's for you. you inspired us to make your humira experience even better...

hidden. the man who seemed to have it all struggled with addiction. he also had serious financial problems. detectives were far from answers, but that would change when someone gave them a name that led to a crucial discovery. here's keith morrison with more. >> reporter: like it or not, it's a fact. an element of human nature some people have affairs. some of them just flings. others a lot more. and as detective ty labay poked through gavin's life, one name kept popping up. chandy. her full name, chanrika creech. she had already told detectives they had had an affair years earlier and he called her before he vanished. but now nine months after he

disappeared, detectives got a tip. her father knew more. >> her dad started telling the tale something his daughter may have seen and he was distraught and wanted to talk about it. he said you know reina? i go yeah, i know the name. >> reporter: she lived with chandy and took care of chandy's grandmother. she said she knew something, something important. >> and he goes i think she knows where the car is. >> reporter: the elusive mercedes. the detectives drove out to see reyna. >> we waited until she showed up. we kind of surprised her. >> reporter: it's what you guys do, right? >> you know, sometimes it works better that way, yeah. she was nervous and startled. wasn't sure what to do. ultimately she provided us the paperwork for the storage locker. >> reporter: her storage locker, it was a big one, ten feet by 20. >> we rolled the door up. the only thing in it was a black mercedes benz with no license plate on it. >> wow. >> a huge moment. >> reporter: a black mercedes

sedan. had to be gavin smith's. >> i kissed my partner on the cheek. that's a true story, it was big piece of evidence. when we were able to get closer and saw our entire crime scene in our opinion was in that car. >> reporter: crime scene, yes, suddenly all other theories seemed to fall away. >> the passenger's seat was completely covered in blood and at one point it was very eerie where you looked at the blood and you can see a hand mark of gavin smith as he died in that seat. >> reporter: soon the news reached the family. tara was devastated. there is no going back from that? >> there is no going back. >> reporter: you accepted it? >> you know, you're forced. you know trauma happens to people all the time. you don't think it's going to happen to you. but it does. >> you know when you already expect the worst, you think that you can't be shocked, but you

can be is all i can say about that. >> reporter: but if gavin was dead and certainly it looked that way, where was his body? how did his car wind up in the storage locker, and above all, who would have wanted him dead? reina lynn seemed like an unlikely suspect. she tells them she rented the storage unit for somebody else. meanwhile, they looked into the affair with gavin and discovered the two had met in rehab. and in december 2010, less than two years before gavin disappeared, lisa found out about it. >> i was heart broken. >> reporter: so she took an extreme step to save her family. she and two of her sons then 14 and 20 went to the house to the creech's house to speak to them family to family. >> i was upset when we were driving there, so i stayed in the car and let my sons go in the house.

>> reporter: but they didn't meet chandy in there, they met her husband. his name was john. john creech. not pleasant. >> when they came out, they were both crying. >> reporter: they told their mom creech threatened to kill gavin if he didn't stay away from chandy. so 17 movnltss later, he vanishes after calling chandy? lisa had a very bad feeling. >> everything changed right then for me. >> reporter: detectives were suspicious, too. remember, chandy told them she didn't see gavin that night. but there was evidence to the contrary. cell phone records showed gavin's phone and chandy's were in the same place that night. a little triangulation narrowed down just where in. >> we came down this street and ut thought this was the likely spot. >> reporter: a likely spot for a tryst, that is? parking lot would be empty at night. so this is a pretty lonely spot. >> it is. >> reporter: so it seemed that

on the night he disappeared, gavin smith met chandy creech your sex, or comfort, or just to talk, something. quite a lot to learn from those phone records. but there was more. a third phone. john creech's phone in the same spot on the same night and this was eerie. creech's phone seemed to be moving in sync with gavin's. >> john creech's phone and gavin smith's phone paralleled each other. >> reporter: together, together? >> sometimes hitting the same towers or parallel towers. >> reporter: what was that like? >> it was an eye opening moment. >> reporter: but when they interviewed john creech. >> he denied ever meeting gavin smith. he said he knew who he was. he knew they were having an affair in the past. >> so despite their suspicions, there was not much police could do. because -- >> one thing we didn't have was gavin smith. >> reporter: that is, they had

no body, no way to prove who killed gavin or that there was a murder at all. >> that is until a dog named buddy went for a walk. a real life dog detective who makes a deadly discovery on a deserted trail. coming up -- >> i go butty, stop. he's just looking at the bush. so we go up there and that looks pretty strange. >> and a young woman suddenly finds herself in the middle of this mystery. >> i discovered he had scrapes on his hand and on his arms. >> when "dark valley" continues. >> when "dark valley" continues. life doesn't stop for a cold.

over 13 million cases reported. restrictions will being put in place coast to coast to stop the spread. including los angeles where a tay at home order goes into effect monday. and fallout continues following the assassination of a top scientist. iran's president pledged to continue iran's nuclear work. now back to "dateline." ck to "d. welcome back to "dateline extra." i'm craig melvin. once police located gavin smith's missing black mercedes, their case began to come together and it pointed to foul play. they found gavin's bloody hand print in the car and started to piece together his whereabouts on the night he went missing. it looked like someone had attacked him, but the trail had not led them to gavin. that is, until one curious dog picked up a scent.

here's keith morrison with more. >> reporter: rocky ramos liked to drive his truck up to the outskirts of the angeles national forest, a place where people tend to toss things like old tvs, maybe some furniture. rocky liked to poke around up here. always with his dog buddy by his side. >> he'd be mad if i didn't take him. >> reporter: in october 2014, they were just five minutes into their hike when something curious happened. >> we were walking up this little area right here and he runs to a bush and i go, buddy, stop. and he's just looking at the bush. he won't leave it or anything. so we go up there and we're looking and it's like, wow that looks pretty strange. >> reporter: buddy made a grim discovery, a human skull. >> i was totally amazed. i was without words, you know, i

didn't know what to think. >> reporter: when police arrived, they found a shallow grave nearby. >> that's where we found him. >> reporter: him. the coroner soon confirmed it, after 2 1/2 years, here was the body of gavin smith. >> the clothing was still intact and he had been wrapped in his own blanket he had in the truck of his car. >> reporter: the coroner also found the cause of death and it was grim. blunt craniofacial trauma, that is, multiple blows to his face. he was beaten to death. >> it was repeated hitting in order to do that much damage, very violent. >> reporter: there were also fractures to the right forearm, possibly defensive wounds. gavin had tried to fight, but clearly, he was no match for his killer. whoever did this was strong, very strong. >> powerhouse gym was very gossipy so if you told the wrong person something your secret

would all over the gym. >> reporter: lauren, just 18 years old back then, asked us not to use her last name. not after she found herself in the middle of a homicide investigation. when police came across her doing under surveillance on john creech. lauren used to work at the pro shop of the power house gym in chatsworth, california. that's where she first met creech. >> he was beautiful. he was tall and he was muscular and a lot of women especially wanted to date him. a lot of men wanted to be him. >> reporter: lauren fell for him. he told her he was separated from his wife chandy, but that didn't stop chandy from calling lauren. >> she texted and called me and was very belligerent and rude. >> reporter: angry, perhaps, that her husband, then 39 was dating a high school girl. in fact, sheer coincidence,

lauren went to high school with gavin smith's son. so she knew when he disappeared in may, 2012, but made no connection between that and something she noticed about her boyfriend, john creech. >> i discovered he had scrapes on his hands and on his arms. >> she didn't think she had anything to do with the disappearance. >> reporter: but when detective o'brien heard about creech's scrapes he immediately thought about gavin smith's wounds. he needed to talk to him again. he found him in jail serving eight years on a cocaine charge, his second conviction for dealing drugs. not exactly an upstanding citizen. could they prove he murdered gavin smith? >> we went to him. didn't ask him questions, put a picture down in front of him of the shallow grave with the wrapped up body. >> reporter: how'd he react to that? >> very wide eyed. the first call to his attorney. >> reporter: hardly a surprise. >> no. >> reporter: other phone calls

were surprising, like the record of calls detectives found in creech's cell phone from the night gavin vanished. john creech was on the phone a lot. >> he was calling multiple people, very intensely. >> reporter: so like three or four or five calls to the same person over and over? >> exactly. >> reporter: some of the calls were to creech's buddies at the power house gym. >> we did a multi-location search warrant. we hit everybody we believed might have helped on that evening. we hit all those houses all at once. >> reporter: one by one those buddies turned. they told detectives how a frantic creech showed up and persuaded one friend to get rid of gavin's cell phone. another friend to hide gavin's car and body in his garage and yet another told detectives she saw chandy and john creech burning their own clothes in the fireplace after gavin was killed. >> this was a strange case. >> reporter: prosecutor bobby graves. >> you don't normally find a

body two years later after somebody is killed. you don't have key witnesses who don't come forward until years later. >> reporter: in january, 2015, nearly three years after gavin smith disappeared, creech was charged with first degree murder. he had pleaded not guilty. and chandy, well -- >> we didn't know if she set it up or if she had something to do with it. >> coming up, an under cover sting and chandy is the target. >> and i was like, stop it. you're going to kill him. i was screaming my head off. and then he comes out of the car, and he's like, you're next! >> then a stunning moment in the courtroom. >> i wanted to get away, i was scared. i was afraid of what i would see. >> when "dark valley" continues. .

welcome back.

nearly three years after gavin smith's disappearance, john creech was charged with his murder. police believed john carried out the rage-fueled killing as revenge for gavin's affair with john's wife, chandy. several of john's associates admitted they helped john hide evidence. but investigators did not think they had the whole story just yet. and there was one person who could give it to them directly. so they figured out a way to get it. once again, here's keith morrison. detective john o'brien and ty labay had a problem. an important witness that wouldn't talk. chandrika creech clammed up. but there's more than one way to get a story. they found an associate of john creech's, someone who knew chandy and convinced him to wear a wire and meet with her. it worked. >> do you want to know the story? >> yeah. >> reporter: once chandy felt safe, she spilled it.

all of it. how she and gavin met in secret at that secluded cul-de-sac. got close in gavin's car. >> all of a sudden the door opens and john just goes like -- and i was like, i pushed myself out this way, got out the driver's side. >> reporter: creech burst in like a machine said chandy, started slugging, wouldn't quit. >> i was like, stop it, you're going to kill him. i was like screaming my head off. he comes out of the car and he goes, you're next and then i drove off. >> reporter: she was terrified, she said, afraid he'd kill her, too, or tell the cops she set the whole thing up. so, did she? again and again the detectives listened to the undercover tape. >> i believe 100% she did not know that was going to happen and she did not set it up. >> reporter: but they wondered, did she help cover it up? it's a serious business covering

for a crime that awful. but chandy had a card to play. she agreed to testify. >> members and alternate members of the jury -- >> reporter: and in june, 2017, john creech went on trial. on the face of it, it looked like a solid case the phone evidence, the cover up the truly appalling crime scene in gavin's car. but did it add up to first degree murder? gavin smith had been dead five years. >> he was killed in his mercedes benz in an act of almost stunning brutality by the defendant john creech who is sitting here in the courtroom. this became gavin smith's tomb. >> reporter: what happened wasn't merely an outburst of rage, said the prosecutor, no, creech had been plotting for two years, ever since he found out about chandy and gavin. after that day back in december

2010, when at their mother's request, gavin's sons met with john creech at his house. >> we just wanted to make sure my dad was not in harm's way. >> were you sobbing and crying? >> yes. >> and what were you saying to the defendant? >> i was begging him not to harm my family. >> reporter: but, they testified, creech told them they did the right thing. >> he ended up saying we saved his life by coming that day. >> reporter: but there were rules. that's what chandrika now divorced from john creech said when she finally took the witness stand. >> as long as their father stayed away from me and had no communication whatsoever, their father would be fine. >> did he say what would happen if he didn't? >> that he would kill gavin smith. >> the affair ended but chandy said the threat remained. >> he did not want me to see gavin, ever.

>> reporter: still attraction is a powerful thing, isn't it? early in 2012, john and chandy were separated but still living together and gavin and lisa were separated, too. and that old magnetic force. gavin met chandy on that secluded road. >> did the two of you become romantic? >> yes. >> did that include kissing? >> yes. >> and while you were kissing gavin, did something happen that caught your attention? >> yeah. >> what happened? >> just something popped up, like appeared. >> was that something the defendant john creech? >> yes. yes. >> reporter: gavin didn't have a chance, she said. >> he repeatedly punched him in the face. >> reporter: so then she ran back to her car terrified. >> i wanted to get away. i was scared. >> reporter: but before she drove away, she looked back. >> john had gavin pinned down.

>> reporter: later, she said, creech wanted her to drive him back to the crime scene, to take gavin to the hospital. a block-and-a-half away, she refused to go closer and dropped creech off. >> why didn't you take him all the way back to the scene? >> i was afraid of what i was going to see. >> reporter: gavin was dead by then, and the prosecutor told them creech wasn't going to any hospital. he was setting out to recruit help for his coverup. >> the first person he calls is jorge. >> reporter: jorge was the first of a series of friends who told an incredible tale. did you ask any of these people what were you thinking? >> they all ultimately said they were trying to help johnny. >> because he's such a nice man? >> because he was a nice guy. >> reporter: nice, when he showed up at jorge's, he was driving the black mercedes and jorge saw something in the passenger's seat.

>> it looked like a body, it was stiff, like a long stick. >> you said it was wrapped up? >> wrapped up in a blanket. >> reporter: eventually jorge got rid of gavin's cell phone. but that very night said the prosecutor, creech called a friend from the power house gym. stan mcquay. >> he asked if he can come over and put the car in my garage. >> is the body in the car at that point? >> yes. mcquay allows creech to keep the body and his car at his house for five to six days. >> yes. is really? >> yes. >> reporter: that's when creech turned to reina lynn, nurse that lived with him. and creech got her to rent a van. >> then he uses a van to drive up to the national forest and he finds a secluded area to bury gavin smith's body. >> reporter: where buddy the dog later found it. but the mercedes benz was still in stan's garage. >> did that upset you?

>> very much so. >> reporter: so weeks later, two men arrived with a trailer. >> did you watch them take the mercedes out of your garage? >> yes, i did. >> reporter: that, said the prosecutor, is when they moved the mercedes into reyna's storage rocker. where months later, the detective noticed one detail that survived the coverup. >> i was looking at the license plate, i see it's not there. should be a california license plate, that kind of thing, it's gone. i also see there is one screw missing and one screw screwed back if halfway and that screw came back positive dna to john creech. >> reporter: bingo, the unassailable link to pull together all that evidence. phone records, chandy's testimony, the friends, the dna, and it all condemned john creech. but a surprise was coming. for everyone. >> raise your right hand.

welcome back. a california jury heard the prosecution's case against john creech, accused of killing gavin smith. they claimed john fatally beat gavin as revenge for an affair with john's wife and presented a mountain of evidence. but the defense was lying in wait, ready to unleash a surprise. testimony from the defendant himself. now with the conclusion of our

story, here's keith morrison. >> reporter: how to defend a man like john creech? well, said defense attorney irene nunez, it was all very simple. creech never intended to kill gavin smith. this was a case of self-defense. >> he had to defend himself against this intruder, an intruder into his marriage. >> reporter: and, she said, only one person could tell that story. >> who is the first witness you are going to call on behalf of the defense? >> my client, john creech. >> reporter: his attorney began asking him about that meeting with gavin's son. >> at any point did you tell them you were going to kill their father? >> no, that's absurd. >> reporter: two years later when it happened, he and chandy were separated. though they lived in the same house. he still worried about her, thought she might be drinking and driving. so he installed an app on his phone that allowed him to track her phone and followed her

because he said he was worried. then he saw her car parked near gavin's and thought it best to talk to them. he didn't sneak up on them, he said. >> so i knock on the hood of the car. >> was chandy sitting on the lap of this guy? >> she was sitting on his lap, they just kept talking. i walked over to the passenger's side door, knocked on the window. >> what did they do? >> chandy opened the door. >> what did she say to you? >> what the [ bleep ] are you doing here? >> he started to argue with chandy, he said. then gavin joined in. >> i'm leaning down to tell him to mind his own business. as i'm leaning down, that's when he leaned up and punched me, pulled me in by my sweater, put his hand on my throat. choking me by the throat. >> reporter: it was gavin who threw the first punch, he said, of course he fought back. >> do you recall how many times you hit him? >> four or five. >> wen were you doing that, what were you thinking? >> i'm thinking how did i get in this situation? i was scared for my life.

>> reporter: then gavin got out of the mercedes, said creech, there was something in his hand. >> there was a 10 to 12 inch stainless steel thing, i thought it was a knife. we fell on the ground and went at it for 10, 15 seconds, exchanging punches. >> at some point, did you get that weapon? >> i kept punching him. until he let go of it. >> what did you do with it? >> i threw it over the back wall of my property. >> reporter: such a weapon was never recovered by the way. but creech insisted there was one, a multipurpose tool of some kind, and it was gavin who provoked the fight. >> i was defending my life. i didn't go there looking for a fight. i was just defending mine. >> i think he lied about everything he said. >> reporter: on cross examination, the prosecutor went for that so-called multipurpose tool. >> so tell us why in the world would you get rid of this weapon that gavin smith had used to attack you with? why would you get rid of that? >> i didn't get rid of it. i threw it behind my house where i knew it would be all right. >> why would do you that? why wouldn't you leave it where

it was? >> i can play armchair quarterback, but at the time it seemed like the right decision. >> reporter: he admitted he made wrong decisions, like asking friends to help dispose of gavin's phone, and car, and body. >> i take full accountably for everything after the fact. if i could change it, i would. >> sir, after you never took full accountability because you never came forward to the police, did you? >> no, not on advice of counsel, i take accountability for that. >> reporter: lisa smith was in the courtroom to hear creech's testimony. >> it was really hard, he was a cruel man. >> reporter: jury deliberations stretched across two days, then the verdict. >> we the jury in the above entitled action find the defendant john creech not guilty of the crime of first degree murder of gavin smith. >> reporter: not guilty of first degree murder. but the jury wasn't done.

>> guilty of the crime of voluntary manslaughter. >> reporter: a verdict, guilty of voluntary manslaughter, in other words, they believed john creech killed gavin smith in a moment of blind passion. >> i was devastated by the verdict. i am still devastated by the verdict. because he did absolutely plan on murdering my husband and thought about it for years and did it. >> reporter: what about creech's friends, jorge and stan, who helped cover up the killing? >> they both had significant criminal liability. >> reporter: so why weren't they charged? >> because we needed them to tell the story about how this man was killed and what happened to him. >> reporter: so they both got immunity. same thing with chandrika, who helped burn bloody clothing and never called the police. >> it seems to me that everybody got deals and everybody got off and that gavin was a victim long after he was murdered. and so are we.

>> reporter: john creech was sentenced to the maximum for manslaughter, 11 years in prison. >> the d.a. in detroit, michigan, indicted mr. creech on federal drug trafficking charges. if convicted his exposure was anywhere from 5 to 40 years in prison. >> reporter: in june 2019, john creech was found guilty of conspiracy to distribute a controlled substance. he was given 10 years, 10 months, to be served concurrently with time for manslaughter in california state prison. lisa smith has done her best to restart her life, she and the boys are in hawaii now, far from the wreckage of that california life. it was never quite as perfect as it looked. >> it was painful to remain there, it's starting fresh. feels like sanctuary.
