college. then an actor turned hollywood movie executive who always made time for his adoring kids. when gavin vanished, his loved ones were at a loss. at first, investigators were, too, unsure if he up and left or if gavin was a victim of foul play. soon, his wife revealed that the missing father held dark secrets and all was not as sunny as it might have appeared. here's keith morrison. >> reporter: there is a kind of peace here, here in her own chosen exile. the vast pacific for company. how else to live with what's impossible to understand or forget. what began that sunny afternoon far away in southern california's san fernando valley, early may 2012. >> something was really wrong,

but a lot more wrong than i could imagine. >> reporter: it was the boy who knew it first, knew something was wrong. his dad was supposed to take him to school that morning. but after school -- >> i was to go to the school and pick him up after basketball practice. when i showed up, he said, "daddy didn't pick me up this morning." and i said, "what?" he said, "daddy didn't show up this morning." >> reporter: it can happen. busy families. people forget. the boy got to school some other way. >> he said he called a friend from around the corner. >> reporter: or sometimes things fall apart. >> the situation sounded too crazy. love affairs, love triangles, drug dealers. it just sounded too outlandish. >> reporter: once those stable, loving pieces have flown apart, how do they come together again? >> somebody is going to walk away from this who maybe you wish wasn't going to walk away. >> exactly. >> how do people sleep at night? how do they live with themselves?

>> reporter: but that afternoon lisa smith knew instantly, something must be wrong. her husband gavin was a dedicated father. >> nothing that would keep him from picking up his kid ever. >> reporter: because gavin was so good at these things, said his sister tara addeo, he was so impressive, so tall. >> you both got the tall gene, right? >> we did. >> whole family. >> whole family. >> reporter: gavin was the tallest, 6'6." >> he walked in a room, you noticed him. you wanted to gravitate to him. he was a magnet. >> reporter: he played basketball for legendary coach john wooden, ucla, 1975. he was a forward. it was wooden's final championship team. >> just to be on that team was pretty fantastic. it was a once in a lifetime. >> reporter: and then he drifted a bit. worked as a golf caddie and this

being los angeles and he a good-looking, towering athlete. people noticed him, movie people. >> they gave him a couple of roles. and he got the bug. >> reporter: the acting bug. first as a body double back on the basketball court in the movie "inside moves" and then as a bartender in "cobb." >> congrats, al! >> reporter: when he met lisa, he was acting, but also waiting tables. >> he twinkled. he was just charming. i was thrilled that he asked me for my number. >> reporter: they married. had three sons together. and with a growing family to support, gavin gave up acting and took a job on the business side at twentieth century fox, eventually as a film distribution executive. >> fox is a wonderful company to work for, and he loved it. it was film. >> reporter: first place lisa called when gavin failed to pick up their son. was he at work that day? >> they told me he just hadn't shown up to work. gavin, in 18 years had never ever not shown up to work.

>> reporter: so then lisa, very worried now, went to the lost hills sheriff station to report gavin missing and waited and waited. days later, gavin's family went on nbc4 in los angeles to plead for help. >> i'm not going to stop until i find him, so please help me find him. >> if you guys just want to each pick up one of these streets. now i'm in panic mode, we've got to do something. >> what did that feel like being 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. >> and i would think with every hour that went by, it would be more and 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 of seasoned homicide detectives to look into a missing person's case. >> they do when there are some suspicious circumstances.

>> reporter: and in this case, they called in sheriff detectives ty labbe and his partner john o'brien. >> his phone was missing. there was no use of it. we checked his bank accounts from the time that he was missing. we checked his medical insurance to see if he had checked himself 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 california's central coast said 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 here, she was sitting right here. >> reporter: gavin's sister tara raced up the coast to the restaurant. >> and i said, here's my brother's picture. did you see him? >> and? >> no.

that was truly heartbreaking to me. >> reporter: it was all a big mistake. but it wasn't the last of the sightings. people seemed to see gavin smith everywhere. >> because he kind of stands out in the photo, you know, big, white smile, tan face, tall guy, pretty much every tall, tan, blonde-haired man was getting spotted as being gavin smith. >> reporter: weeks, months passed. no sign of gavin. and with no answers, lisa was forced to reveal something publicly, something painful and maybe crucial. coming up -- what had happened to gavin smith? >> it didn't make sense to me. and so i just kept -- no, it can't be. it can't be. >> we said, i think this is a suicide. and then we go i think this is a murder. our gut instincts are going

different ways. >> you wondered if she had something to do with this? >> it crossed our minds all the time. somehow, it kept playing back, why won't you search? why? >> when "dark valley" continues. [sneezing]

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, idolized 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 seemed 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 possibility he was out there somewhere, and lisa could. and i wondered whether there were ever sort of dark nights to your soul where you thought i wonder if she had something to do with this. >> it crossed our minds all the time. it just did. i mean, did i think that 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 -- >> yeah. >> -- they're no longer living. >> and you must have a reason for knowing that. >> that's what i would assume. >> reporter: and it turned out lisa did know something, just not what tara suspected. there were secrets, which lisa and gavin kept hidden. >> i was the love of gavin's life. he adored me. our family was 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 stuntman 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 get 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 had felt in years. >> reporter: but when detectives john o'brien and ty labbe learned about gavin's addiction, they had to consider a raft of new possibilities. >> he disappeared. maybe he overdosed. we didn't exactly have any of those answers. >> driving all over the valley, we would have moments in the car of where we looked at each other and said, "i think this is a suicide." and then an hour later, we'd interview somebody or something would happen, and we'd go, "i think this is a murder." and our feelings and our gut instincts were going different ways very early on very fast. >> yeah. it's got to be pretty unusual though? >> it was very confusing. >> reporter: confusing for lisa, too, because here was another secret, the smiths were

underwater on their mortgage. on the verge of losing their home. >> we were in a horrible position financially. >> reporter: lisa discovered that 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. >> uh-huh. >> 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 and to see if she had any information. >> did she? >> no. the relationship had ended, and 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 a month before he vanished, she was not his first affair. there had also been a woman named chandy. 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 she said that she had not been in contact with him for some time, but then they started communicating via e-mail. >> and that would explain the fact that he called her on the

phone? >> yes. >> reporter: but chandy said she didn't see him may 1st, hadn't heard from him since. last sighting? a colleague saw him driving his black mercedes. >> we felt that 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 until she showed up and kind of surprised her. she was very nervous, startled. >> a new witness and the game-changer of a clue. >> i kissed my partner on the cheek. it was pretty exciting. it was a big piece of evidence. >> you think that you can't be shocked, but you can be. >> when "dark valley" continues.

disappearance, they learned that gavin had troubles he kept 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 and others a lot more. as detective ty poked through gavin's life, one name kept popping up, chandy. her full name, chandrika creech. she'd already told the detectives that she and gavin had an affair years earlier and that he called her right before he vanished. but now, nine months after gavin disappeared, the detectives got a tip. her father knew more.

>> chandy's dad started telling a tale about something his daughter may have seen, and he was distraught and wanted to talk about it. and he said, "well, you know reina?" i go, "yeah, i know the name." >> reporter: reina lim? she lived with chandy. she took care of chandy's grandmother. chandy's dad said reina knew something, something important. >> and he goes, "i think she knows where the car is." >> reporter: the elusive mercedes. detective labbe and his partner john o'brien drove out to see reina. >> we just waited till she showed up, and we kind of surprised her. >> that's what you guys do, right? >> you know sometimes it works better that way, yeah. she was very nervous and startled and wasn't quite sure what to do. but ultimately she provided us with the paperwork for the storage locker. >> reporter: reina's storage locker. it was a big one, ten feet by 20. >> we rolled the door up and the only thing in it was a black mercedes benz with no license plates on it. >> wow.

>> 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 a big piece of evidence. and we were able to get closer and saw that our entire crime scene, in our opinion, was inside 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 when you looked at the blood and you could see a handmark of gavin smith as he died in that seat. >> reporter: soon the news reached gavin's family. tara was devastated. >> there's no going back from that. >> there is no going back. >> 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 lim certainly seemed an unlikely suspect. she told them she had rented the storage unit for someone else. meanwhile, detectives looked further into chandy's 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 heartbroken. >> reporter: so she took an extreme step to save her family. she and two of her sons, then 14 and 20, went to the creech's house to speak to them, family to family. >> and i was really upset when we were driving there. so i stayed in the car, and i 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 months 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. >> we came upon this street here, and we thought this was a good spot. >> this was a likely spot. >> yeah. >> reporter: a likely spot for a tryst, that is. >> parking lot though would be empty at night? >> yes. >> yes. >> and so this is a pretty lonely spot. >> it is.

>> reporter: so it seemed that on the night he disappeared, gavin smith met chandrika creech for 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. >> together together. >> together. sometimes hitting off the exact same towers or parallel towers. >> wow. what was that like? >> that 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, that he was having an affair with his wife in the past. >> reporter: 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. in coming up -- >> i go, buddy, stop. and he is just looking at the bush. so we go up there and we're looking and it's like, wow, what is -- that looks pretty strange. and a young woman suddenly finds herself in the middle of this mystery. >> i discovered he had scrapes on his hands and on his arms. >> when "dark valley" continues. . until i found out what it actually was. dust mite droppings! eeeeeww! dead skin cells! gross! so now, i grab my swiffer sweeper and heavy-duty dusters. duster extends to three feet to get all that gross stuff

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 lookin' at the bush. he won't leave it or anything, so we go up there, and we're looking, and it's, like, wow, what is -- that looks pretty strange. >> reporter: buddy had made a grim discovery, a human skull.

>> i was just 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 they 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 that he had in the trunk 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 be 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 while doing surveillance on john creech. lauren used to work at the pro shop of the powerhouse gym in chatsworth, california. and 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 sons. 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 he had anything to do with the disappearance. >> reporter: but when detective o'brien heard about creech's scrapes, he immediately thought of gavin smith's wounds. he needed to talk to john creech again, and he found him in jail serving eight years on a cocaine charge. his second conviction for dealing drugs. not exactly an upstanding citizen. but could they prove he murdered gavin smith? >> we went to him, didn't ask him any questions, just put a picture down in front of him of the shallow grave with the wrapped up body. >> how did he react to that? >> very wide eyed, and the first phone call he made was to his attorney.

>> that's hardly a surprise? >> no. >> reporter: but other phone calls were surprising. like the record of calls the 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. >> so like three or four or five calls to the same person over and over. >> exactly. >> reporter: some of those calls were to creech's buddies from the powerhouse gym. >> we did a multi-location search warrant, and we hit everybody that 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 late that night. how he persuaded one friend to get rid of gavin's cell phone. got 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 grace. >> you don't normally find a body two years later after somebody is killed. you don't normally 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 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 undercover sting and chandy's the target. >> and i was like, stop it. i was like 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 believe 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. >> reporter: detectives john o'brien and ty labbe had a problem. an important witness who wouldn't talk. chandrika creech had 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. they convinced him to wear a wire and meet with her. it worked. >> do you want the whole 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. >> and then all of a sudden the door opened, and johnny just goes like -- and i just like 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. >> and i was like, stop it, you're going to kill him -- i was like screaming my head off. and then he comes out of the car and he's like, "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% that 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 coverup, 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's sitting here in the courtroom. this became gavin smith's tomb. >> reporter: but what happened wasn't merely an outburst of rage, said prosecutor bobby grace. no, he said, 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 that my dad was not in harm's way. >> were you sobbing and crying? >> yes. >> and what were you saying to the defendant? >> i was just begging him not to harm my family. >> reporter: but they testified creech told them that they did the right thing. >> he ended up saying that 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 did? >> that he would kill gavin smith. >> reporter: 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 like 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, help him 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? >> because i was afraid of what i would see. >> reporter: gavin was dead by then. and the prosecutor told the jury creech wasn't going to any hospital. he was setting out to recruit help for his cover-up. >> so the first person he calls is jorge valles. >> reporter: jorge valles was the first of a series of friends who told an incredible tale. >> did you ask any of these people a central question, what were you thinking? >> they all ultimately said that they were trying to help johnny. >> because he's such a nice man. >> because he was a nice guy. >> reporter: nice? when creech showed up at jorge's house that night, he was driving gavin's black mercedes, and

jorge saw something in the passenger seat. >> it looked like a body. it was just stiff, like a stick, you know, a long stick. >> and 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 powerhouse gym, stan mcquay. >> he asked if he can come over and if he can park his car in my garage. >> was the body still in it at that point? >> yes. >> reporter: mcquay allows creech to keep the body and the car at his house for five to six days. >> really? >> yes. >> reporter: and that's when creech turned to reina lim, the nurse who lived with them and took care of chandy's grandmother. creech got reina to rent a van. >> and then he uses the van to drive up to the angeles 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. >> and did that upset you? >> very much so. >> reporter: so weeks later, two men arrived with a trailer. >> and did you watch them take the mercedes out of your garage? >> yes, i did. >> reporter: that, said prosecutor grace, is when they moved the mercedes into reina's storage locker. where, months later, detective labbe noticed one crucial little detail that survived the attempted cover-up. >> i was looking at the license plate, and i see that it's not there. there should be a california license plate. it's not -- >> you'd kinda think. >> it's gone. and i also see that there's one screw missing and one screw screwed back in 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. coming up -- >> i was scared for my life. >> a dramatic tale from the stand. >> he punched me, pulled me in by my sweater, put his hand on my throat, he's choking me by my throat! who attacked who? and who would the jury believe? >> my skin was just crawling! it was really hard. it was really hard. >> he's a cruel man. >> when "dark valley" continues.
