mind that he is guilty. >> now after four trials, the final verdict is in. >> i'm not guilty. i didn't do this. cal harris seemed to have it all. a beautiful family and successful business and big house to the lake. september 11th, 2001 as the world was watching what is happening in new york, the family was caught by heartbreak. cal's wife had disappeared. here with the house on the lake is keith morris. >> it's a long winding ride. this tale studded with

surprises. >> i felt like i was being kidnapped in broad daylight and no one can help me. >> reporter: it's the story of his life and theirs. >> we cannot sit here in silence and watch another trough -- travesty of justice to take place. >> do you remember much about your mom any more? >> not really. >> it's been a long time. >> it's about what happened on a september day the rest of the world can't forget. is there a corner of your brain thinks maybe it was somebody else? >> not at all. not at all. >> 15 years, four trials. would it never end? >> i put my head down. i went numb. i just went numb. >> this is the climatic chapter in a family saga one that began in a moment all but drowned out in the chaos of history. it was september 2001. harris kids were little.

7, 6, 4, and it. they lived in this patch of wilderness with a patch of lake behind. >> kids have a lot of happy memories out here. it was a very unique and special place that we were fortunate enough to purchase, you know, years and years ago. >> reporter: unique and special place only a prosperous person could perform like the prominent car dealer cal harris. he taught his kids to love it. you went hunting with the kids here? >> hunting, fishing, you name it. we swim the lake, jet ski in the lake and water-ski and my kids bring their friends out and like to be outdoors. a fun place. >> christmas was always fun. >> reporter: i can't imagine. >> opening presents, playing with the new things you get. >> reporter: i can't think of a more idealic place to have christmas. did it feel like that at the

time? >> yeah. >> reporter: it was here in this patch of paradice, said cal, that he woke up one morning, years ago, to find that his wife michelle wasn't home. she had gone to work the evening before and didn't come back. mary harris is cal's aunt. >> he didn't know where she was and didn't know what had happened. >> reporter: woke up and she wasn't there? >> and honestly he didn't -- it wasn't something he seemed comfortable talking about a lot. i think it was very emotional for him. >> reporter: she was gone. gone without warning. her friends distraught. called her cell phone. they heard her cherry cell phone message haunting them.

>> reporter: there is something else about this you should know. the night michelle harris vanished was not just any night. it was september 11th, 2001. >> things were in disarray. >> so they were and no one was paying much attention about the disturbing events in oswego, new york. >> troopers were sent to new york city. there is a skeleton crew left at all of the stations. >> reporter: back then she took the call and the morning of september 12th. what do you do? >> i sent two investigators over to take you to cal harris and a u.s. trooper up to the house. >> reporter: cal opened up his house to them. >> he said look wherever you want. i want it know what happened.

>> reporter: she knew she had a missing person case on her hands. >> we kept hoping as everyone did that michelle would call her house or call one of her friends and show up. >> reporter: cal said his aunt mary was completely focused on his four children and had to leave it to others to search for michelle. >> his thing was, okay, it's time for them to go to school and now it's time for me to pick them up. i have to be sure if this is the routine normal for them, we will keep them in their routine. >> reporter: but where was their mother? there was a clue and it didn't look good. michelle's van had been left at the foot of the long driveway leading up to her house out here on that big country lot and the keys were still in the ignition. but where was she? all of these cameras searched the house outside 200 plus acres to look through. >> that area was homesteaded

early in the late 1800s and a lot of wells. >> reporter: didn't find anything? >> no, we didn't. >> reporter: not at first or outside but a few days later they did. >> i entered the residence through the opened garage door. >> reporter: senior investigator steve anderson. >> i noticed blood stains on the floor and on the moldings of the doorway that led out to the garage. >> reporter: and more blood, tiny stains on a kitchen rug. they sent it out for tests. >> everything on the floor, on the inside walls and on the carpet came back to being michelle's blood. >> reporter: and suddenly the case looked very different. >> then we knew we had a real problem. >> reporter: what in the world happened to michelle harris? coming up. >> they had what would appear to be an idealic life in a beautiful home and beautiful children. we learned more and more, he became the focus. >> reporter: a husband suspected. a daughter questioned.

-good luck, everybody. michelle harris, 35-year-old mother of four, was missing and new york state police investigators sue muscly felt sure of one thing. michelle had not abandoned her children.

>> the clear picture we developed is michelle would never leave her children, ever. >> reporter: so was it foul play? after all, michelle's van was abandoned at the foot of her driveway. and that blood on the garage floor and in the kitchen alcove, testing proved it was michelle's blood. >> there is a lot of blood in the garage and spread over a wide area, and there's a lot of blood splatter, i mean, over 60 drops of blood that has been not just dripped but splattered by some force on that throw rug. >> reporter: and, yet, didn't make sense. this woman, wife of an affluent car dealer, devoted mom, seemed like an unlikely victim. >> and they have what would appear to be an idealic life and a beautiful home and beautiful children. >> reporter: it got off to a story book start. he, the attractive wealthy car dealer, she a pretty young woman from modest means opening phones at a harris county car

dealership. >> my mother had his office across the street from mine. and i just saw her one day and just kind of evolved from there. >> reporter: what attracted the two of you to each other? >> she was very outgoing and very attractive, and good personality. >> she was a knockout. she was funny. she was vibrant. >> reporter: anti-mary harris was taken by cal's new girl. michelle, she said, was a woman up for anything. >> athletic. let's have a good time. you know? jump on the jet ski. jump on the four-wheeler. >> reporter: wasn't as dainty as you think? >> no. >> reporter: and not shy of retiring type either? >> no that is part of why -- their personalities to me seemed to really mesh. >> reporter: michelle fell hard too for the man and his lifestyle. gary taylor is her dad. >> he won some dealership thing and they went to switzerland, i think. >> reporter: wow. >> i mean, there was a lot of perks there that she had never

had before, so. >> reporter: in august 1990, michelle and cal got married here beside empire lake. >> a great day. a beautiful setting and very relaxing. not very stressful. just kind of it being a big party afterwards. >> reporter: the fairy tale rolled on. kids kept coming. they built a house on empire lake and here on their private preserve they were a family in motion. fishing, swimming. skating. michelle and all of it. the kids, of course, grew older. taylor is the oldest. followed by kayla and jenna and tanner. their mom? about her, they have no real memories. >> been a long time. >> reporter: it's true. most of your lives. and how old were you? >> i'm not sure how old i was but i don't have any memories. >> reporter: jenna is often told by those who knew michelle how much she rervels her mom. >> i have seen pictures of per.

she is really pretty and she is always smiling and seems like a very happy person, so it makes me feel good that people see me in her. >> reporter: and with that terrible loss, say the kids, they have grown up happy and content for the most part. all thanks to one person. tell me about your dad. what kind of guy is he? >> funny. >> reporter: funny? >> he is funny and the most caring guy in the world. he is nice and we are his whole world and he is protective and just loves us so much. and wants the best for us. >> reporter: protective dad who said he tried to shield them as best he could from the not so happy times. >> michelle was really struggling with those kids at a young age, which i totally understood. what i noticed was that she was just drifting away from being a stay-at-home mom and i understood that.

>> reporter: there was friction in the harris family. he loved order and she not so much. >> she had had a room downstairs and called it a chuck room. if there a party or picnic, she would throw it and take it down to the chuck room. >> reporter: as she told friends and family had he a controlling temper. she called her sister-in-law one day from a closet terrified. >> he had a gun outside the closet and she was inside hiding gentleman what did you hear about that? >> he was out there as a pump gun, i guess, and he was racking the pump action pped and telling her to come out. >> reporter: cal later denied it was true that he had been fighting or threatening michelle with a gun. then in 1999, michelle learned cal was having an affair. she was devastated but not ready to end the marriage. and cal said he wasn't either. >> michelle said that, you know, we can work through this but, you know, you got to get rid of the killer. she worked up at the courtland dealership. >> reporter: they did what they

could to salvage the marriage. it didn't work. she told her family he cut off her spending money. she took up with a young man in november of 2000. a month later she told cal she wanted a divorce. her family said he didn't take it well and things in that big house in paradise grew strained, indeed. why did she stay in the house? >> her attorney had advised her to stay in the house and to not leave. >> reporter: so they divided the parenting duty and worked on a settlement. michelle got a job as a waitress at a local restaurant and bar. that's where she was the night of september 11th. she finished her shift about 9:00, had some drinks with two coworkers and drove to her boyfriend's apartment and left there about 11:00 but that is we believe the last time anyone saw michelle harris. >> we did a lot of work on a lot of different people early on and it wasn't until they were eliminated and then we learned

more and more about calvin, that he became the focus. >> reporter: the district attorney even tried to speak to the eldest children. didn't accomplish much beyond frightening them, apparently. >> i know i just sat there and cried the whole time. i didn't talk. i wasn't allowed to be in there with taylor. >> reporter: how old were you at the time? >> i was in fourth grade and he was in fifth grade. so 9 and 10. >> reporter: the d.a. jerry king said he interviewed plenty of other witnesses who convinced him that the police had the right man. in september '05, four years after michelle disappeared, they charged cal harris with murder. >> three state police and personnel literally busted into my office and kicked the door open. the three of them jumped me and handcuffed me and shackled me and walked me out the front door of my office. >> reporter: you got a taste of law and order up close and

personal? >> yeah. >> reporter: the d.a. was going to take the case to trial even though there was no body, most murder weapon and even though he, himself, was by no means convinced he could prevail. >> i thought that it was maybe a 50/50 shot at a conviction. i thought that a jury could go either way. >> coming up. >> it hurts. absolutely. all of it was just taken away. >> prosecutors come on strong. >> he told her that he would put her body in a place where it would never be found. >> when "dateline" continues. ws hey, who are you? oh, hey jeff, i'm a car thief... what?! i'm here to steal your car because, well, that's my job.

in september 2005, four years after his wife vanished, cal harris was charged with murder. >> oh, it hurts, absolutely. you know? i had a good standing in the community. hi a successful business. donated my time and money and resources to a lot of good causes in the community. raised my kids in that community and, you know, all of it was just taken away. >> reporter: but the county d.a. had been convinced that cal killed his wife late on the night of 9/11 and sgofed dispos her body. >> the more i talked to people close to her the more convinced i became he did. >> reporter: the trial began in 2007 with the prosecution claim that cal harris is man used to being in charge of everything

and everyone in his life. >> he is in control of his businesses, he is in control of his wife, he is in control of his finances, his employees and his children, and just kind of a domineering person. >> reporter: more than that, said the prosecutor, cal harris could be volatile. michelle harris began to keep notes about what she said was abusive language and behavior. in fact, she won a retraining order against him. >> he said i doned need a g't no kill you. he went beyond telling terrible things to her. he told her he would put her body in a place that would never be found and that is one of the biggest facts of the case that we have looked and looked and looked for this woman's body and have not been able to find it. >> reporter: the harris family babysitter a woman named barb

thayer said she found michelle's van parked at the end of a long driveway. >> she yelled in the house is michelle here? the defendant said without missing a beat said we better go get the car. >> reporter: according to the babysitter, cal didn't seem surprised. >> it's all these hundreds of little things that convinced me that he's just not acting like someone would act if they didn't know what had happened to their wife. >> reporter: later that morning, when new york state troopers talked to cal, they, too, made note of his demeanor. >> he seemed kind of unconcerned. he was more concerned with getting michelle harris' van cleaned up and back on the lot. >> reporter: the motive, said the prosecutor, was simply

money. cal had learned that michelle was demanding an appraisal of a car business that she intended to take a piece of it in the divorce? >> all of a sudden, everything is out of his control. >> reporter: so the argument went if michelle disappeared, cal's problems did too. >> he was going to have his finances scrutinized. he was perhaps not going to be able to stay in the marital residence. >> reporter: final that blood. they called it medium velocity splatter and had been left there only recently. >> i think it could have been the most important part of the case as far as placing michelle bleeding in the house with some force having been applied to that blood and no explanation for it. >> reporter: so what happened

that night? prosecutor keen put his theory to the jury. >> she got home that night about at 11:30, parked her car, went in through the garage door and instance she got inside the house, she was struck with something by the defendant. >> reporter: she went down on the kitchen rug, he said, was struck again. that blood splatter. >> so this would put her down either on her knees or on her bottom and she is being struck and the blood splatters on the door and on the carpet. took her back out into the garage and laid her down on the garage floor. she must have bled some onto the garage floor because there is an area three feet by six feet where blood was found. >> reporter: then, said the prosecutor, cal tried to clean up before he disposed of the body. >> he then would have taken the car back down to the end of the driveway, walked back up to the

house and disposed of the body during the seven hours or thereabouts before he called mrs. thayer. >> reporter: the defense attorneys tried to swat it all down and cal harris, himself, was adamant he had nothing to do with his wife's disappearance. >> it's one thing to say, look, i'm innocent, i didn't do this but another thing to have so many people accusing you and pointing the finger at you. look. i'm not guilty. i didn't do this. i didn't commit this crime. >> reporter: there was no body, no murder weapon and the defense said the forensics were unconvincing at best but the jurors weren't having it. june 2007 they came back guilty. cal harris broke down and sobbed. >> because i knew i was going to not see my kids. i knew i wasn't going to go home that night and i knew how they were going to be and it was overwhelming. >> reporter: but in the eyes of michelle's family, it was finally justice. and then?

then an extraordinary thing happened. >> my first reaction was, come on. the judge is not going to accept this guy's claim. >> reporter: a new witness with an amazing story and it turned the harris case on its head. itd the harris case on its head. coming up. >> as i was going by the harris property, there was a blond woman out there, looked like she was crying. i know it was her. >> reporter: had someone seen michelle? >> the most bizarre story that you could have ever told. >> reporter: get ready for trial number two. when "dateline" continues. when "dateline" continues. your cravings. you know what i do instead? i snack on blue diamond almonds. wasabi & soy sauce?! mmm! don't deny your cravings. eat 'em! all the flavors you crave, in a superfood. blue diamond almonds. crave victoriously. i'm and i'm an emt.erer when i get a migraine at work, it's debilitating. if i call out with a migraine, that's one less ambulance to serve a community.

. our top stories. sunday marks four years since donald trump announced his 2016 presidential bid at trump tower. on tuesday the president will kick off his re-election bid with a rally in orlando. o.j. simpson has launch add twitter account which he says he

has, quote, a little getting even to do. this week marked the 25th anniversary of the murders of simpson's wife nicole brown and her friend ron goldman. now back to "dateline." welcome back. i'm craig melvin. in 2007 cal harris was convicted of killing his wife michelle but there was still a small glimmer of hope. a new witness was about to come forward who could possibly shed light on what really happened that night michelle disappeared. here again is keith morris. >> reporter: what happened here in oswego in 2007 was almost unbelievable. cal harris convicted of killing his wife michelle was about to be sent for 25 to life. suddenly, it all blew up right in d.a. jerry keene's face.

>> i came in the courtroom thinking the defendant was going to sentenced it anded up being more of my being on trial. >> reporter: who on earth had the power to make this happen? he did. kevin tubbs. >> i know that she was there, okay? i know she was. >> reporter: kevin tubbs. a plain spoken farm back then was hauling hay and why was he so important? because after six years during which tuff's war he barely registered the fuss over the harris case, he picked up a paper and saw the story of cal's conviction, and. >> i seen that and, you know, i started, like, recalling, you know, thinking like, oh, my god. >> reporter: just like that! he suddenly knew, he said, that what he saw the morning after 9/11, the morning michelle harris disappeared, was important. it was between 5:30 and 6:00 in

the morning, he said, he was hauling a load of hay. >> as i was going by the harris property, there was a blond woman out there and a young gentleman, you know, in his early 20s. >> reporter: standing by a pickup truck. >> my lights were right on them. >> reporter: hardly more than ten feet away, he said he looked straight at the young man, saw he was dark haired and muscular and visibly angry. >> he looks at me like this, like what do you want? >> reporter: and the woman? she was looking down. >> just by her face, looked like she was crying. she was either upset or wasted. >> reporter: the woman he said, he was certain of it, was michelle harris. >> i know it was her. >> reporter: was it true? if kevin tubbs really did see michelle in the early morning hours of september 12th then the prosecutor's case was in ruins because cal harris couldn't have murdered her some seven hours before. an innocent man had just been

convicted and so the judge tossed out the verdict, called for another trial and sent cal home to his kids. many, including michelle's family thought tubbs' story was bogus. >> everybody knew he was lying. it was the most bizarre story you could have ever told. >> reporter: and, of course, when trial number two opened in 2009, the prosecution attacked tubbs' credible. why wait six years to come forward? still for the defense tubbs was pure gold and a man to create reasonable doubt. >> there simply isn't enough evidence to convict cal harris of murder. >> reporter: bill easton was one of cal's attorneys. >> you had an eyewitness and ear witness. none of this direct evidence is present in this case. >> reporter: the prosecution argued that cal showed how unfeeling he was by failing to join the search for michelle. that was nonsense said his aunt mary. cal was simply trying to keep it

altogether for his small children. >> there were dozens, maybe hundreds of experts scouring the area looking for her and there was one person taking care of these four kids. >> reporter: that alleged motive that cal was worried the dealerships would take a hit because of the divorce? not so said cal's side. his lawyer told him michelle couldn't touch the business and that any way before she vanished michelle had dieded to accept cal's settlement offer $740,000. >> she had indicated to numerous people she was happy with the settlement. >> reporter: besides, said aunt mary. >> it was plenty of money to go around. and no amount of money would have made cal say, ah-ha, for $2 million i'm just going to wipe her out. >> reporter: then there was the blood. splatter in the kitchen alcove, could have been a cut finger

said the defense but any way nobody could really tell when it was left there. the prosecution claim that cal tried to wash away blood on the garage floor. >> there is a small amount of diluted blood that was found days after the new york state police had walked through this particular area of the house while they were conducting the search. >> reporter: walking out is not going to destroy the blood cells. >> it could dilute it if their boots are wet. >> reporter: finally, the defense decided jurors needed to hear from cal harris as a caring father, not as the husband the state made him out to be so the defendant took the stand. >> it was nerve wracking at first p obviously, my life is on the line and my kids, their lives are on the line. >> reporter: he admitted to an affair, blamed himself for the end of the marriage but denied he had threatened, hurt, or tried to control michelle. if anything, he said, michelle had been living a bit of a wildlife staying out all hours just before she disappeared. >> she came and went as she

pleased. she had money to spend. wasn't tracking her down. the babysitters were here, the nannies were here and she was off doing -- i don't even know what she was doing. >> reporter: was it enough? the jury deliberated for almost two days and it wasn't guilty again. >> takes your breath away. you know? it's like getting stabbed in the stomach and just i'm numb. you know? i had already been through it once. >> reporter: family and friends stepped in, took care of his small kids who began a weekly ritual visiting dad in prison. taylor, the eldest. >> you go and see him two hours a week and a bunch of other people talking and it's loud and can't really have a private conversation. leaving was definitely the hardest part for us. i mean, he held it together well. >> reporter: what was it like

driving? >> it was quiet. >> reporter: watching his kids walk away week after week, said cal, was unimaginably hard. >> it was the worst. i went back to my cell and just laid there for hours and hours and just closed my eyes and tried to block it out. >> reporter: three years rolled by. then came a day in october 2012 when cal harris found himself crying for joy in the prison yard. coming up. >> it's rare, though. this is really rare. >> yes. >> a new chance at freedom and new urgency from the kids. >> this is kind of our time to come out and do our part. >> and a whole new thorough of the case. >> it's all coming together. >> it's time to look elsewhere. . >> trial number three. when "dateline" continues. when "dateline" continues. new coppertone sport clear. not thick, not hot, not messy, just clear, cool,

answers. >> i think that theit was a goo for us to finally come out and talk about it. >> reporter: how did it feel to do it? >> good. >> we newell it was time to come out and give our side and do our part in this. >> reporter: cal hired new lawyers and they condemned the state for an investigation which they said was blind any suspect but their client. the defense attorney bruce barket. >> they have pursued this man for 14 years with scant evidence, evidence that really no prosecutor should bring a case on. >> reporter: the defense went back to witnesses the police had interviewed years before, talked to others, and heard a whole new story of michelle's last hours on earth. earlier trials they said revealed the mother of four had been hanging with an unsavoring crowd, coworkers and customers from her waitressing job. attorney ieta. >> there were people there had

facial hair, his height, his age, and the type of vehicle he drove. >> reporter: tubbs said the man he saw was standing beside a black truck. stacy stewart owned a black truck. same kind and it's a new model and it's a chevy. you look everything up and it's all coming together. >> reporter: stacy stewart has denied any involvement in michelle's disappearance and he has denied he ever had a relationship with michelle. he said he was never even alone with her. still cal's side was convinced that stewart and a friend of his played some role in michelle's disappearance. in 2015, trial number three opened to the town of schohaire a change necessary said the defense because the case was too well known in tioga county and the defense managed to get some of the prosecution's case thrown out. the state wasn't allowed to suggest, as it had before, the blood was spilled around the time that michelle disappeared. >> to have forensic scientists

happened to her. it's time to look elsewhere. >> reporter: there was a new prosecutor this time, tioga county's kirk martin. he made the same arguments the previous d.a. did and said the harris -- the trial took three months. finally, late april, the jury got it and the waiting began. michelle's family still con vinned that cal was guilty. >> is there a corner of your brain that thinks, maybe it was somebody else? >> not at all. not at all. >> well, cal and his family hoped the jury had been persuaded otherwise. >> you know, you have been confident when you've gone on trial because you have said, i didn't do it. i should be acquitted, and yet, you weren't. how does that impact your thinking now? >> just by what bruce and his team have done in the investigation. it's got to create some doubt.

we didn't have that before. >> so your honor certainty. by this time it was a way of life for the children. >> i think, if things don't go our way, it will definitely turn all our worlds upside down. but i know we're tough enough that we'll get through it. you definitely don't like to think about that kind of thing. >> we have plans what we want to do. >> want to talk about that at all? >> vacation. >> yeah. >> maybe. maybe not. it's the end of cal harris' third murder trial. his lawyers were determined to show there was reasonable doubt in the case. but would that be enough to persuade the jury? >> coming up -- >> breaking news out -- >> would you believe trial number 4? >> shocked.
