>> this is a woman who said, i saw the murderer and it wasn't tom foley. >> would her story be the ultd mat twist? >> we can tear out your heart. >> "mystery at heath bar farm." good evening. welcome to "dateline." i'm a lester holt. it's a mystery people thought they had the answer to, the murder of a teacher, within hours police were on the scene. there would be an arrest, a trial and a conviction. case closed? not on your life. because in this story a bombshell came in after the verdict. here's josh mankiewicz. >> 911. >> i need an ambulance now. >> february 2009, coldwater, michigan. >> what's the problem? >> my wife! >> your wife? >> yes! >> in one day, one moment -- >> is she breathing? >> no! she's gone! she's gone. >> -- the innocent, simple life tom foley and his family once lived was gone forever. >> oh, my god! no! oh, my god! >> gives it off to foley. >> it was a moment tom foley never would have imagined 23 years earlier. back then, number 30 -- >> going to be 15 seconds left exactly. >> -- scored the winning basket giving his high school the regional title. >> it's good! he hit it with five seconds to play. >> and earning young tom a places in coldwater's basketball hall of fame. >> i get goose bumps talking about it. >> like victory was snatched from the jaws of defeat and he came through with it. >> to what extent were you sort of known around here for being the kid who hit the game-winning shot? >> that went on for a long time. maybe someone might come up, hey, tom, remember when you hit that shot? i say, of course i remember. >> in 1991, the hometown hero started dating another local standout named darlene weber. dar, as she was known, had a personality as big as her smile. >> the first time i saw her, she was playing soft ball, of course, and she had on these lime green rec specs so she looked a little funny. but when she took them off, i thought she was beautiful. >> it was a classic case of opposites attracting. >> i think we both went into the relationship knowing that we really loved spending time with one another. >> tom was the laid-back, easy-going type. dar an elementary school teacher was more type a, and she didn't hide what she was thinking. >> she had opinions and she'd let those be known. it's one of the reasons i loved her. i still love her today. >> still, dar's sister la donna, lynn and marla learned that dar and tom intended to marry, they were left scratching their heads. >> my famous saying was, there's got to be something wrong with tom for him to stay with dar. >> because you couldn't do it. >> no. >> no. >> you couldn't be around somebody who was, what, that much the center of attention? >> no. >> telling you what to do. >> that controlling. >> dar was not a domesticated person either. >> the foleys were married in 1994 and right from the start dar took the lead. fair to say she wore the pants in that house? >> i'd say probably 75%, 80% of the time she did. >> she was the breadwinner? >> yes. >> you stayed home and took care of your son? >> i did. >> heath was tom and dar's only child and the center of their lives. >> and we just loved being together. we were always together. >> and so the three foleys lived on the outskirts of coldwater in an old farmthey called the heath bar farm, a picture-perfect family. until that winter day back in 2009 2009. what was the last thing you said to her? >> i said, i love you, and i'll see you later. >> on that day, the foleys were preparing to celebrate heath's tenth birthday at a friend's house just down the road. dar still needed to shower so tom, heath and a friend of heath's left without her. the plan was for dar to follow in her own car and meet them all at the party later that afternoon. but dar never arrived. that gave you some sort of sixth sense that something was wrong. >> yes. she was always on time or early to events. >> so tom left the party and headed back home in search of his wife. >> our kitchen back door was open, and i noticed that the glass was broken and there was glass all over our kitchen floor. soy looked through the rest of the house for her and ended up finding her in our bathroom. >> it was a gruesome scene, dar lying in the shower stall. she had been shot in the head with a shotgun at point-blank range. tom immediately called for help. >> what's the problem? >> my wife is in the shower. she's just laying there in the blood. >> first responders rushed to the foley farm. when michigan state police detective james carbon arrived on the scene, he noou heknew he was in for a long night. >> we don't have a lot of homicides that happen in and around branch county. because of her position as a schoolteacher, just for the number of people that knew her, that put it in a much more serious type investigation. >> detective cash berbon and his state troopers scoured the crime scene taking pictures and seizing evidence of what appeared to be a home burglary gone wrong. the first clue? the broken glass coming from the kitchen door window. >> it appeared that a beer bottle was used to break that particular window. >> according to tom, jewelry and credit cards were missing. the family deck had also been disturbed and financial documents inside were gone. and then there are was the medicine cabinet. >> looked like somebody had gone in and scooped a shelf off the medicine cabinet and its contents. >> like maybe they were looking for prescription drugs. >> potentially. >> but to detective carbon, the items missesing weren't nearly as telling as what was left behind. expensive electronics were untouched, as was dar's purse found sitting on a hallway chair. >> it just didn't make a lot of sense. >> neither did the use of a shotgun. >> it's large, potentially bulky. if you're going in to break into something you have to carry whatever you steal out with this shotgun that you brought also. >> it wasn't until the next day that police found their first significant piece of evidence, evidence that led the investigation in a whole new direction are. down in the foleys' dusty basement was a suspiciously dust-free yellow plastic bag. what was in the plastic bag? >> three shotgun shells. >> i found a bag with a shotgun shell in it. have you ever seen that before? >> no. >> new questions for the grieving husband from police and dar's family. >> there were a number of people that were really offended by his demeanor. - this is for cindy. i wanted to get her something special this year. - you went to kay. she'll love it. trust me. i know. - more milk?

>> i told him that someone had hurt mommy. he goes, is she in heaven? and i said yes. >> it seemed that no one in coldwater could comprehend what had happened, including steve and joanie pierce, close friends of both tom and dar who learned of the murder from tom himself. >> i said, the three of you were always together and he was crying and he said, i know, i know, i should have been there for her. and then i said, if you would have been, the three of you would be dead now instead of just dar. >> but just 24 hour noose the investigation, detective jim carbon of almost abandoned the theory that this was a random act of violence. >> it appeared to me to be a staged break and entering to hide a homicide that took place. >> but according to detective carbon, whoever staged the burglary didn't factor in the weather that day. >> it got really warm. we had a huge snow meltoff. >> the ground around the farmhouse was unusually wet and muddy. >> so you would expect that there would be muddy footprints from inside the residence where somebody would come through that door. >> absolutely. >> was there any footprints, anything? >> there was nothing. >> but it was the yellow bag found in the basement, the bag containing shotgun shells, that interested carbon the most. >> downstairs in the basement we found a plastic bag that had some shotgun shells in it. >> okay. >> did you ever see that before? >> no. >> the foleys didn't own a shotgun shotgun as far as we know. >> that's correct. >> carbon sent the bag to the lab for analysis. what technicians found on the bag surprised even this veteran detective. tom's fingerprint was on the bag. >> yes. >> suddenly detective carbon felt he needed to take a closer look at tom foley and his seemingly picture-perfect marriage. >> i think they did a lot of things together, however i don't consider them the picture-perfect couple. >> neither did dar's sister lynn, in whom dar once confided. >> she said, tom doesn't love me anymore. he's leaving me. he's going through his change of life, you know. >> his midlife crisis. >> yes. >> dar's sisters were becoming increasingly suspicious, especially they said after watching tom's behavior at dar's funeral. >> it was almost like he was relieved. >> there were a number of people that came up to me after the service that were really offended by his demeanor, his joyfulness. >> these are things that i've heard heard, it's ridiculous. i mean, taking care of heath was on my mind, wondering who killed my wife was on my mind. they don't know the ningthings that i had been through. >> maybe so, but detective carbon was with keeping a very watchful eye on tom foley. he decided to interview the other foley who was at the farm the day dar was killed, tom and dar's son heath. >> heath, i'm detective sergeant carbon. >> on that day, heath and his friend skyler watty were inside the house playing video games, waiting to be driven to heath's birthday celebration. >> did you see anything different or oust the ordinary or anybody walking around, anybody come up to the door? anything that you could think of? >> not really. >> okay. >> the detective also interviewed skyler watty who said right before leaving for the party tom sent the two boys outside to go start up the truck. >> he said that he'll be out there in a little bit. >> okay. >>ive don't i don't know what he was dog in there, taking a shower or what. >> like heath, skyler couldn't recall anything unusual about that day either. and then suddenly -- >> yeah. when we were outside during across the barn there was like a big crash, like way in the back of the house. >> like what did it sound like? >> it sounded like breaking glass and a bunch of things falling. like a vase just -- >> it was a loud sound. >> yeah. >> detective carbon showed skyler a drawing of the foley farm and ask skyler to place an x where he believes the sound originated. >> like somewhere around here? >> skyler placed the "x" just outside the first floor bathroom, the same room where dar foley had been shot. >> it appeared to us that skyler watty may have heard the shotgun blast that killed dar foley. >> detective carbon was also thinking this. one other person in that house at that time was tom foley. coming up -- >> he wanted the house. he wanted her money. and if he divorced her, he lost everything. >> was that a motive?

we're waiting for you. >> that's what i would do. >> according to detective karbo, tom didn't bother calling dar at hoax because he knew dar was already dead. then members of dar's family stepped forward, to testify that tom and dar's marriage was troubled and that tom wanted out. >> he told me that his wife is very controlling and that that was wearing on him and he did not necessarily want to stay in the marriage anymore. >> and there was more evidence of an unhappy marriage. according to this woman, back in 2006, tom had a wandering eye. >> please state your full name for the record and spell your last name. carrie zuk. >> carrie zuk taught at the same school as dar and was known at school as dee dee. that's how carrie met tom. >> he told me he was thinking about leaving dee dee. also, she revealed he had feelings for her and later he tried to kiss her. >> what was your reaction to that? >> i didn't want anything to do with it. >> the prosecution wasn't done. this woman took the stand. >> please state your full name for the record and spell your last name. >> marianne victorian crandall. >> out of the presence of the jury, marianne crandall told the court that, like carrie zuck, she met tom through dar and a couple of weeks after dar's murder marianne stopped by the farm to offer tom support. >> i don't mean to embarrass you, but you had sex with tom in his living room? >> he tried to. and it was stopped. >> who tried and who stopped? >> he tried, and we both stopped. >> you don't have a sexual relationship with somebody within two weeks after your wife's been murdered in that house. >> but the jury never heard marianne crandall's testimony because there was no indication of a romantic relationship prior to dar's murder, the judge ruled, just as he did in the first trial, that her testimony was prejudicial and therefore inadmissible. it was a huge blow to the prosecution's case. >> it supports the position that they weren't this deeply in love couple that he kept trying to present. i mean, that would have proven that. >> but norris still had her two key witnesses, tom's own son heath and heath's friend skyler watty, both two years older and now more certain than ever about what they saw and heard the day dar was killed. >> last year at church camp i went for one of our activities we fired shotguns and it most resembled that sound. >> then it was time for heath to take the stand. the last time tom had seen his boy was at a hearing, also in court, almost a year earlier. >> while you're in the barn, do you hear something? >> yes. i thought it was maybe skyler kind of ran into a wall, either that or a gunshot. >> you think the boys actually were, if not eyewitnesses then earwitnesses to murder. >> earwitnesses to what happened. >> tom schafer knew if he had any hope of getting tom foley acquitted, he'd need to prove the sound those boys heard was anything other than a gunshot. just two weeks before trial began, while inspecting crime scene photos, schafer found what may be the key to his client's freedom. >> and i says, ted, is that what i think it is?

>> the boys. the testimony of the boys. they heard the gunshot. >> but the defense was about to argue that over time both boys' testimony had changed and in significant ways. >> heath is now stating that it sounds like a gunshot? it's something that he didn't say in the first interview. the same thing with skyler. >> heath's courtroom testimony left tom furious, not at his son but at his accusers, the people who had cared for heath while tom was incarcerated. . that's somebody coaching him or encouraging him? >> i believe so. >> coached or not, tom foley's defense team knew from day one that they needed to prove the sound those boys heard was tom dropping a window frame on the back porch and not the fatal gun blast. four days after tom foley's arrest, schafer and cuberstein took a trip to the farm to try and do just that. >> couple of perry mason moments. don't come very often. >> this is the frame that we found. >> right where tom said he dropped the frame, they found this tiny shard of glass. immediately they tried to match the shard with the frame tom said he dropped. >> if you take the shard and set it in one of the few remaining, intact areas of the frame, you can see it fits perfectly. >> it was compelling evidence that tom may have been telling the truth. but schafer would need more than a shard of evidence. he next called this woman, janette moore, the woman who came forward immediately following tom's guilty verdict are and the reason he was ultimately granted a new trial. >> i do. >> moore said she was driving past the foley house right around the time dar had been murdered. >> as i provoapproached, it this white car come racing out forward, and if i hadn't have braked i would have hit him. >> janette moore said she got a good look at the driver. >> it was a young 18 to 20-year-old kid, had real black hair, and his face was real white. he was clenching the wheel just like this. and i thought, he's crazy, he's going to kill somebody. >> why didn't you call the police? >> i didn't because i was afraid. >> but when janette moore learned about tom foley's guilty verdict, she said she could no longer p keep her silence. >> god forgive me and i truly mean that in my heart that i didn't come forward sooner. if i hadn't been so darn scared. >> what followed was a succession of other witnesses, each claiming they too saw mysterious cars either on or leaving the heath bar farm right around the time of the murder. >> i caught a glass of a ford -- black ford suv/crossover vehicle. >> it could have been a white car, cream car. it was just a light-colored car. >> whoever killed dar foley was either in one of those cars or all three of them participated in this murder in some fashion. >> but tom foley knew if he had any hope of acquittal the jury would need to hear from one more witness. >> i call tom foley to the stand, your honor. >> i just didn't want to convince the 12 jurors. i wanted to convince the prosecutor are. i wanted to convince the police. i wanted to convince my wife's family. i wanted them to know and look at me and hear me he. >> tom started by answering some still-nagging questions, like, how did a yellow plastic bag with shotgun shells in it get into tom's basement? >> did you have those bags in your home? >> yes. >> how do you explain the bag in the basement with the shotgun shells in the basement? >> they weren't ours. the bag is probably ours. my fingerprint is on the bag. but for three clean shotgun shells to be in my basement? it just doesn't make sense. >> you have no idea where those came from. >> absolutely not. >> tom said he's never owned or used a shotgun. >> never. wouldn't know how to operate it. wouldn't know the first thing about it. >> tom schafer then asked why tom failed too call had his home when dar didn't show p up at the birthday celebration. >> something just wasn't right so that's why i went home. if we had cell phones i would have called her on the cell phone. i had to find her. i had to see where she was at. >> then it was time for tom to describe his relationship with dar. it didn't take tom long to lose his composure. >> we were very close. and we were -- >> go ahead. >> we were together all the time. >> tom admitted to the jury he did once flirt with carrie zuck, but with he said that happened three years prior to the murder during a brief time when he and dar were arguing more than they were communicating. >> at that >> that put a lot of distance between us and it also led to int massescy problems between her and i. >> tom said he eventually told dar about his feels for carrie. he also says he went to counseling to work on their kmujs communication problems. >> after those sessions did things get better?
