they were madly in love. at least their affection revealed them. they were both having affairs. as investigators started to dig. they found that someone had been playing spy games and the stakes could cannot have been higher. here's andrea caning. >> sarasota, florida, the perfect backdrop for romance. beautiful beaches for long walks, gorgeous sunsets. and a slow rhythm of a gentle gulf tide. stories of love abound in this city by the sea. but not all have ended happily ever after. like the one thatlded here back in the summer of 2012. when secrets, lies and infidelity led to murder. >> 911, what's the location of

your murder. >> a man's been shot. >> it's really a twisted love story. >> it's so twisted. >> it's tangled. it's a knot. >> i'm not sure that it will ever come undone but i do know that there is more to the story than has been told. >> it all began back in 1998 when a 26-year-old local firefighter by the name of sam dreher met the love of his life danielle laborvo. >> they were the ideal young couple, they held hands, looked at each other dreamily over dinner. he seemed crazy about her. >> sam's older sister cindy lutz was thrilled when she found out sam had a serious new girlfriend. >> what was your first impression? >> she was really sweet. she seemed crazy about him. she liked the outdoors and liked to travel. to travel.

so they had a lot in common. >> so it came as no surprise when sam announced he was ready to pop the question. as for how he proposed, the firefighter didn't disappoint. >> he had hired a sand sculptor to build a rather large sand sculpture of a treasure chest and then he it placed the engagement ring in the box. >> so there was some real pirate booty in there? >> right. he pulled the ring out, got down on one knee and proposed to her. >> sam is a romantic. >> isn't he. >> the newlyweds would become equally successful at work. sam rose to the rank of lieutenant at the young age of 33. >> he loved the fire services. absolutely loved it. loved being a paramedic. >> danielle was just as ambitious, finding her stride in the administrative office of a local office. -- local hospital. >> she became the regional marketing director for the whole hospital corporation. >> sam and danielle didn't have children, but they had the next

best thing, sam's great niece aubrey cake. >> you're like the daughter we never had. they always told me that. >> aubrey who attended college nearby often spent weekends with the drehers. he was just like a regular dad. he really just cared. focus on school, don't let those boys ruin your life. they're no good. don't let those boys get around you. he's like and you're never allowed to date a fireman. >> what's wrong with firemen? >> he just worked with them and knew how they were. so. >> did danielle also take you in like you were one of her own? >> yes, she was as welcoming as he was. >> aubrey listened to their tales romantic trips to exotic lands. >> they traveled the world together. they had so many good times and so many great experiences. i would imagine they were almost like role models to you. >> yeah, they were, they were. >> the perfect life, perfect wife. everything just seemed great you know, for both of them.

>> but all that changed in august of 2012. it was a hot saturday afternoon in sarasota when registered nurse trish murphy heard a disturbance coming from the stair well just outside her apartment. >> it sounded like somebody was being chased and then i heard somebody yellow, god, no. >> the unmistakable sound of gunshots followed. four of them in quick succession. trish immediately called 911. >> 911, what's the location of your emergency? >> i just heard gunshots and somebody screaming outside and somebody running outside. >> trish slowly peered out of her apartment door and saw a man lying in the stair well bleeding. she knew he wasn't a resident of the apartment complex. >> i had no idea who he was. my concern was to get him over on his side because he was face down in a really big pool of blood. >> trish wasn't the only one at the scene. her upstairs neighbor, dianne mcknight also tried to aid the victim.

>> there was just blood everywhere. and i didn't -- i just didn't know what to do. i ran back into my apartment and got towels. >> as the minutes ticked by, trish began to worry the shooter might still be in the area. >> then all of a sudden, you start to think, wow, i wonder where the person is that did this and for all i knew, the person upstairs shot him. >> but those questions would have to wait. soon paramedics arrived on the scene. they learned the victim was one of their own. it was firefighter sam dreer. the paramedics immediately little airlifted him to the nearest trauma center as word of the shooting spread. >> and it's danielle. she's screaming into the phone. you have to come. he's been shot. he's been shot. and i said who's been shot? and she screams out sam. >> cindy jumped in her car to be

at her brother's side. a thousand questions swirled through her mind. why sam? who shot him? and why was he at that apartment complex? >> a firefighter gunned down. but this seemed like more than just a random shooting. when we return -- >> there's some infidelity going on and there's a reason a cause for concern. better things than rheumatoid arthritis or psoriatic arthritis. when considering another treatment, ask about xeljanz xr, a once-daily pill for adults with moderate to severe rheumatoid arthritis or active psoriatic arthritis for whom methotrexate did not work well enough. it can reduce pain, swelling, and significantly improve physical function. xeljanz can lower your ability to fight infections like tb; don't start xeljanz if you have an infection. taking a higher than recommended dose of

>> it was a nightmare. it seemed like we were traveling a thousand miles. we just -- we just could not get there fast enough.

>> it was a nightmare. it seemed like we were traveling a thousand miles. we just -- we just could not get there fast enough. >> when cindy finally made it to the icu, sam's wife danielle was already there waiting in the hallway. >> she started crying. and i said is he alive? just tell me he's alive. she said he's alive. >> but the prognosis wasn't good. >> and the doctor said he was shot four times and i'm thinking wrong place, wrong time. i didn't know what happened. >> the responsibility of finding out what happened fell to detectives chad mcdonald and jarek szalbirak who began gathering pieces of the puzzle as soon as they arrived on scene. >> this case was personal to you. >> in our area, law enforcement and firefighters are very close, in this case, it wasn't just

another victim. this victim was part of this larger brotherhood and it kind of hit home. >> first, they interviewed the two neighbors who find sam lying in the stairwell. >> whenever we work a crime that's usually where you're going to start with is your 11 caller. >> trish murphy told the detectives this normally quiet upscale go ahead community had never experienced anything like this before. >> it was a nice quiet place to be. >> but she did remember seeing something that troubled her one evening just a month before the shooting. >> a man standing in the woods across the lake staring at the building. >> i thought to myself that that was an odd thing. who would just be standing there. >> detectives then turned to trish's traumatized neighbor dianne mcknight and they learned dianne was holding on to a secret. >> it turns out that the witness, dianne mcknight was a lot more than just a witness. she was very important to this case. >> yes, she was.

>> dianne revealed that she knew sam intimately. >> she admitted that they were boyfriend and girlfriend. she had stated that they had had only been dating for a few months, and stated that they were in love. >> so sam was having an affair. >> yes. >> which is why sam was at the apartment complex that day. >> there's some infidelity going on and there's a reason a cause for concern. >> did you ever think that you'd be the kind of person to have an affair? >> no. >> dianne told the detectives her affair with sam started as fairs so often do, with an innocent encounter at a bar. >> he asked me, you know, like if i was married and had kids. and i told him that i was and that no kids. i'm like what can about you? he said yes, married. >> in fact, sam had been married for 13 years. but according to dianne, it took just a month for sam to fall in love with her. and she said, the feelings were mutual. >> what was it about him that

made you fall so hard? >> he was just the most thoughtful person. he was just comforting. and i just couldn't wait to the always just be around him. >> did you still feel a little guilty? >> oh, yes. >> but dianne said there were already issues in her marriage. >> i just thought if i'm doing this, my marriage is definitely already over. >> a few months after the affair began, she decided it was time to tell her husband she wanted a divorce. >> i remember just saying we need to talk. nobody ever wants to hear that. and he looked at me. he said, are you having an affair? >> wow. >> and i said no. >> why didn't you just be honest at that point? >> i didn't want to hurt him. >> what came next? >> we both got very emotional and he agreed to it. >> then came the shooting.

>> dianne tried to think of anyone who could have been responsible. that's when she remembered a strange visit a month before the shooting from main claiming to be a plumber. he said he was looking for a water leak in the building. >> he needed to check her pipes or something along that line. >> i said okay. thinking what am i doing letting this strange person in my home? i just had this feeling of this just isn't right. >> five minutes later the plumber was done and on his way. >> do you ever check with your superer? >> yes, i called the office and told him the incident and they said there should not have been anybody at my door. >> oh, that must have been just a weird feeling. > it was very unneving. >> the following day, the same man appeared again. right below her apartment waldenny. >> he was standing down there on the ground by a tree, and looking directly up right at me. >> that's creepy. >> yes. >> now are you thinking i'm being stalked? >> yeah.

>> dianne then saw him a third time. this time immediately after sam had been shot. >> that same man. it just gave me chills. >> came running up the stairs towards me. i just looked at him and said what are you doing here? >> she recognized him and you can hear her on a 911 call. >> i didn't see -- i don't know. >> what are you doing here? >> i remember him just kind of making this motion like whoa. then he ran off. >> did you start to think in those split seconds that this mystery man was really after sam? >> yeah, i mean it was definitely a suspicion. >> it must have been such a puzzle. >> yes. >> puzzling too for detectives. >> we needed to know what he this connection was. >> coming up, more secrets waiting to be revealed. >> she said i need to you sit down. i have something to tell you. and the hairs on the back of my neck stood up. >> when "dateline" continues.

while sam dreer clung to life in icu, diane mcknight remained at the crime scene, wondering who could have been responsible for his shooting. how scared are you knowing that there's a shooter on the loose? >> you was terrified. >> she told detectives about the strange man she had seen multiple times around her apartment complex. the same man who appeared moments after sam was shot. >> they said could you describe him? i described him. >> little did she know a man fitting that very same description had just been arrested. he had approached sheriff's deputies moments after they arrived on scene and confessed to the shooting. >> the deputy that had him in the back of the patrol car already told us that he made statements that he was the shooter. >> did you feel like this could be an easy one, case closed or did you think there's got to be more to this story? >> there's never an easy one. there's always more to the story. >> the man identified himself as michael minor. detectives mcdonald and szalbirak immediately brought

him to the sheriff's office for questioning. >> he's very distraught but he's willing to talk to us. we were very much ready to listen to him. >> he outlined for detectives the details of the shooting. he started by insisting it was all an accident. >> but detectives weren't show so sure. after all, michael shot sam not once but four times. >> one of the shots was to the back of sam's head. >> so sam is laying here and michael is right on top of him basically giving him the final shot? >> he would have had to have been. that's what the evidence indicates. >> one shot might have been an accident. not the three or four shots that he actually fired. that was no accident at all. >> but detectives wanted to know if this wasn't an accident, why then did michael shoot sam? >> got all these pieces to the puzzle and you try to fit them all together. >> that's when michael revealed something that would turn the case on its head. he told detectives about an affair.

but it wasn't the affair between sam and dianne. it was an affair he was having with the victim's wife, danielle dreher. >> they had been having an affair for four years. >> it was a mind-spinning moment. detectives had just discovered the victim, sam, had been cheating on his wife, danielle. now they were learning danielle had also been cheating on sam. >> everybody here is involved with somebody else. it was interesting, to say the least. >> and challenging for detectives who now had to contend with a second affair. mike minor, the plumber, 13 years younger than danielle, told them the two had met on ashley madison, a website for husbands and wives looking to cheat. the website's slogan? life is short, have an affair. >> this was someone looking to have an affair. >> they both were. >> yeah. >> but michael insisted this was no casual fling. after all, the affair had lasted four years.

what's more, he told detectives he had fallen in love with danielle. >> it was like i really found my soulmate, man. it was so wonderful. i really had every intention of marrying this girl. >> he was smitten. i mean, he was totally obsessed with her and in love with her. >> he went on to say that on the day of the shooting, he decided it was finally time to talk to sam, man-to-man. he wanted to come clean about his love for danielle. >> he wants to the confront sam, basically tell him that he's the other man. >> i concocted this scheme to go up there and tell him you know, yeah, i'm seeing your wife. >> that day, michael said he tracked sam down and found him in the parking lot of diane's apartment complex. he also said he brought a gun because will he no idea how sam would react. >> he's bigger than me so i just brought my firearm, you know? i intended to go up there and just scare him. >> but according to michael, his

mano-e-mano with sam didn't go as planned. when sam saw michael was armed, he fled. >> don't run. >> don't run, you know? i'm trying to like freaking force him to talk to me. >> michael ran after sam up these stairs. he said at some point while the two were in the stairwell, sam turned. >> michael claims that he was in fear and closed his eyes and just fired his gun. >> then he, you know, comes toward me and i just you know, i just -- i closed my eyes and i just pulled the freaking trigger and i'm so sorry. >> with all the things he's telling you he's in a relationship with danielle, do you start to think we need to talk to danielle dreher? >> yes, so the next step was let's hear danielle's story. >> so detective szalbirak left michael and headed to the hospital where danielle had been waiting for updates on sam's condition. all she had been told was that sam had been shot. no one told her by whom.

>> when i got over there, she was crying. she was very upset. >> detectives recorded the interview. >> we're trying to piece what all happened. >> okay, let me get calm here. >> at first detective szalbirak didn't reveal he knew about danielle's lover michael miner, or that it was michael who shot sam. instead he started by asking danielle about her marriage to sam. danielle candidly described it as troubled. >> we had been not getting along for many months. >> danielle also explained that she knew sam was having an affair despite sam's best efforts to conceal it. >> do you know where he went today? >> today? i'm sure he went to his girlfriend's, yeah. but he always goes to her house. i'm not surprised by that. >> danielle then admitted she too was unfaithful. >> she was pretty straightforward, told me about the affair. >> it was wrong. i shouldn't have done it. nobody should cheat. >> little by little, the detectives led danielle to believe they were focusing their

investigation on her lover, michael. >> so it would kind of shock you if michael went and confronted him? >> yeah. >> that's what happened. >> really? >> and we have michael. >> do you? >> it wasn't the reaction the detective was expecting. he found danielle's tone to be strangely flat and unemotional. >> that was troubling to me. that was disturbing to me. >> i cannot believe he did this. >> danielle went on to say she had no idea michael planned to talk to sam that day. >> so michael never said anything about going over there? >> no, he didn't. >> but detectives were skeptical. they wondered if danielle knew more about michael's intentions than she was letting on. >> at this point, i don't know whether to believe her or not. >> you're not done with danielle dreher? >> oh, no, we're not done with her. >> for the time being, szalbirak left danielle at the hospital to be with sam's family it was up to danielle to reveal the identity of the shooter and explain the sordid details of . how she was connected to him. >> she said, i need you to sit

down. i have something to tell you. and the hairs on the back of my neck stood up. >> first, cindy learned sam and danielle were getting a divorce. then that both danielle and sam were having affairs. most shocking of all? it was danielle's lover who shot sam. >> did i just hear what i just heard?. >> four adults ensnared by lies and deceit. one clinging to life, but this tangled story was about to get a whole lot more twisted. >> coming up -- >> danielle was just fully obsessed with what sam was doing, which went beyond anything that i've seen before in investigations. >> when "tangled web" continues. .

i'm dara brown with the hour's top stories. in remarks to reporters tonight, president trump doubled down on

his threats to iran, iraqi parliament to expel u.s. troops, saying the u.s. could, quote, charge them sanctions like they've never before seen, ever. wildfires in new south wales in australia today, 60 homes have been destroyed throughout the state. now back to "dateline." welcome back to "dateline extra." i'm craig melvin. investigators did not have to wait long for the plumber to appear. michael miner surrendered to police at the crime scene. he claimed the shooting was an accident, but to detectives, his story was not adding up. as they dug deeper into the case, sam's family was facing a heartbreaking decision. once again, here is andrea canning.

24 hours after sam dreher had been shot, his condition began to deteriorate rapidly. sam's sister, cindy, was there when the family decided to take him off life support. >> i hated it. i thought of him like he was one of my children. i loved him that much. >> were you able to hold his hand were you able to be with sam? and say good-bye? >> i did. >> what did you say to him? >> i made him a promise that the people responsible for his murder would pay for it. >> the news of sam's passing hit dianne mcknight hard. >> in my mind i'm still thinking maybe there's still some hope that he can survive this, but when i heard that, i knew that i was never going to see him again. >> sam's great niece, aubrey cake, didn't make to it the hospital in time, but she made sure to be at sam's funeral. >> the bagpipes, i still

remember to this day. >> did it make you really proud in that moment? >> yeah. i'm still proud of him. >> full fire department honors were bestowed upon the admired young lieutenant. >> it was like the whole community came out to pay their respects. it was very humbling, very, very humbling. >> but along with the tears, there was tension. by now, sam's family and friends had learned danielle's lover had shot sam. >> no one could believe it, that she even had a boyfriend, or that it was her boyfriend that killed him. >> people didn't even want her at the funeral. >> but the drama didn't end there. sitting not far from danielle was the other woman. was that awkward with danielle being at the funeral, the wife and the mistress? >> yes, it was. but i felt it was more important for me to be there than worry about how awkward i felt. >> to her surprise,

sam's family embraced dianne. >> they all received me well. in fact, they invited me to come up and sit with them. >> she's truly a lovely person. and i think she made him happy. and he deserved to be happy. >> you've come down pretty hard on danielle for her affair. sam was also having an affair. >> yes. >> do you condemn him for that behavior as well? >> no. i don't think he intended to meet someone. i don't think he intended to have an affair. he met dianne. he had known her three months. that's a far cry, you know, a world apart from danielle seeking a man on ashley madison and having a long-term affair with him for four years. >> in the weeks following the funeral, detectives mcdonald and szalbirak continued their investigation. they had their shooter, but they also had lingering questions about whether danielle may have

somehow been involved. >> obviously, one of the first things that comes to mind, the wife has a hand in this. she's linked. she's got to have something to do with it. >> and as mcdonald and szalbirak sifted through the evidence, they became more confident they were on the right track. what they discovered stunned even these two seasoned investigators. for over a month danielle had been spying on both sam and dianne. >> danielle was just totally obsessed with what sam was doing, which went beyond anything that i've seen before in investigations. >> what's more, it appeared to them that danielle had persuaded michael to help her. >> they had basically stalked them. >> they actually put a tracker on their vehicles. >> this is spy equipment? >> correct.

>> sheriff's disputes disputes deputies discovered it in the wheel well of sam's pickup. police also found evidence that both danielle and michael were taking surveillance photos of sam and dianne. this is a photo taken of them on sam's boat. in this one, they're on dianne's balcony. >> michael would have been somewhere across the lake there. and that's where he would have been hiding in the bushes. >> it seems like a perfect spot, actually, if you wanted to spy on someone. >> absolutely. >> but detectives said the couple only got bolder from there. they discovered evidence michael had brazenly broken into dianne's apartment and videotaped the inside. >> inside the belly of the beast. >> he's narrating. i believe his first words were, i'm in the belly of the beast. and his first thing when he pans over was of the alarm pad where it wasn't armed. >> that could have been bad, huh? >> as michael documented every aspect of dianne's personal life, poking around her drawers, her refrigerator, even inside her bathroom, police said danielle played lookout. in this text message to michael, danielle wrote, get out of there if you aren't already.

getting bad feeling. >> and he's doing it at the request basically of danielle. >> but what detectives found most alarming were the text messages michael and danielle sent each other. >> michael mine or writes, i want to blow his head off and then put two on her just for good measure. he goes on to say, bang bang, done. i won't, though, because it's wrong. danielle later responded, you would not and could not because that would be illegal. >> that was definitely disturbing. >> in another text, danielle referred to her handgun, which she called daisy. she wrote, i am so close to introducing them both to daisy. michael responded, ha, ha, we can do it together. as a date. smiley face. in yet another, she wrote, i hate them with every inch of me. revenge will be mine, and it will be very, very sweet.

>> it was very obvious that danielle had some kind of hatred towards sam, that there was -- that she wanted to hurt him. >> and based on those text messages, it seemed clear to detectives that she had persuaded michael to feel the same way. >> i absolutely think she poisoned michael's mind as far as what sam was. >> everything he knew about sam was that he was a violent person. he was described to him as a drunk, as a cheater, as a liar. that knowledge came from one person and one person alone. it was danielle. >> did you have any evidence as you kept investigating that sam was abusive or violent toward danielle? >> there was no evidence of that whatsoever. >> danielle definitely had control over michael minor. she did manipulate him. did she manipulate him to the point of killing sam? i don't know. >> detectives mcdonald

and szalbirak realized they needed to pay danielle dreher another visit. >> we're going back to find out what is your intent? what is your involvement with this? >> coming up -- did someone have a million reasons to commit murder? when "tangled web" continues. whs whatever happens out there today,

remember, you have the hilton app. can the hilton app help us win? hey, hey-we're all winners with the hilton price match guarantee, alright? man, you guys are adorable! alright, let's go find your coach, come on! book with the hilton app. expect better. expect hilton. patients that i see about dry mouth. they feel that they have to drink a lot of water. medications seem to be the number one cause for dry mouth. i like to recommend biotene. it replenishes the moisture in your mouth. biotene definitely works. [heartbeat]

a peaceful night sleep without only imagine... frequent heartburn waking him up. now that dream is a reality. nexium 24hr stops acid before it starts for all-day, all-night protection. can you imagine 24 hours without heartburn? welcome back. detectives investigating the murder of sam dreher had made a stunning discovery. sam's wife danielle and his confessed killer, michael minor, had been spying on the firefighter and his girlfriend for ev for more than a month. even more chilling were text messages danielle and michael shared, filled with violent fantasies. detectives suspected that

danielle had been manipulating her young lover and it was time to find out how their spying turned deadly. back to andrea canning. you couldn't write this as a movie. you couldn't write this as a book. it wouldn't be believable. who does this? >> tracking devices, surveillance photos, sneaking into an apartment. sounded more like a couple of private eyes than a plumber and a marketing director. dianne recalled a time she and sam were eating at this restaurant when out of nowhere danielle appeared. >> all of the sudden this woman comes up from behind sam. and she said, i'm danielle, the soon-to-be ex. you must be the next. >> whoa, awkward. >> yeah. i just wanted to get out of there. >> danielle then left them without incident. did you think you were being followed? >> no. i thought it was just a big coincidence, out of all the places. like, now i know why she was there.

>> this is like marital espionage. >> exactly. it's exactly like that. they were playing spy games. >> now it was up to mcdonald and szalbirak to find out if all those spy games somehow developed into a conspiracy to commit murder. >> i became very suspicious that she had a part in this homicide. >> detectives sat down with danielle and recorded interviews with her on three separate occasions. from the very first interview, danielle willingly acknowledged that she and michael had been tracking sam and dianne. >> where did you put the tracking device on the vehicle? >> i put it up under the driver's side rear wheel. >> okay. >> and i've been tracking him for about a month and a half. >> danielle also admitted to helping michael take those surveillance photos. >> who took the pictures? >> michael did. >> okay. whose camera? >> mine. >> but danielle denied that all this elaborate spying escalated into a murder plot.

instead, she said it was simply preparation for her pending divorce. >> and i told the attorney about it. and the attorney said, whoa, you're good because, he said, that's good evidence. >> she wanted to be able to just have leverage and be able to embarrass him. >> danielle told the detectives another reason was plain old curiosity. >> i had to see for myself that it was a girl. it broke my heart. >> how did you -- >> i don't know why because i was cheating on my husband. >> and that's the big question, right? you were doing it for four years and why -- why did it break your heart? >> i think i still loved my husband, still had feelings for him. >> what's more, danielle said she and michael had stopped their spying weeks before the shooting. detectives also asked about those text messages which they found so troubling. danielle said they were all in fun. they first questioned danielle about the texts michael sent her. >> i want to blow his head off and then put two in her just for good measure. do you remember him saying that?

>> i don't. but he's said it before. he would say things like i'll kill the [ bleep ]. >> did you ever think he was serious? >> no. >> they then asked danielle about the messages she sent back to him. >> i'm so close to introducing them both to daisy. >> i remember saying that. i didn't have daisy with me, though, at the time. nor would i do anything with a gun. i mean, i think i was trying to impress michael in a weird way. >> do you think they're joking with each other, or do you think it's real? >> i asked danielle that very question, why? why are you saying this? and she just said, oh, i'm just trying to sound tough. so she denied this to be for real. >> but that's not the way sam's sister saw it. when detectives showed those texts to cindy, she was dumbstruck. >> i could not believe what i was reading. this is someone who's been in my

family for almost 13 years. even talking about it with you now, i have chills. >> those texts, she said, proved just how much danielle hated sam and wanted him out of the way. and she's convinced danielle manipulated michael to feel the same way. do you think that danielle had anything to do with your brother's death? was she somehow directly associated? >> i think she is. i hold danielle dreher as much if not more responsible than the man that actually shot him. >> cindy told detectives she believed hatred wasn't danielle's only motive, that she was also driven by that age-old incentive. >> i believe it was the money. to divorce him and split half of it is one thing. but to get all of it? i think it was money. i think it was always money. >> just over a million dollars, in fact. >> there was a substantial amount of money that she was going to gain if sam turned up dead.

and that's exactly what happened. >> wu we asked danielle dreher to sit down with us for an interview. both she and her attorney declined. but during danielle's interview with the detectives, she emphatically denied having anything to do with sam's murder. >> i would never kill my husband. i would never kill another human being. >> and the man who pulled the trigger supported danielle's claim of innocence, in no uncertain terms. >> i've acted on my own. i did. i did this all on my own. you know, i just -- >> so you're indicating that danielle's only involvement was in order to help you basically get dirt on her husband to help with the divorce? nothing to do with harming him? >> right. >> but michael's response didn't sway cindy lutz. >> i didn't believe him. i think he was protecting her. i think he would have done

anything for her. >> cindy believes that includes lying about danielle being involved in sam's murder. and cindy wasn't alone. >> do i believe that she was part of the murder scheme? yes. >> sarasota county lead homicide prosecutor, karen fraivillig, believed danielle manipulated michael to kill sam. >> she's a very manipulative person, and she was able to manipulate michael minor, and there's a dead man because of that. >> the question now before the prosecutor, could she prove it in court? >> coming up -- will one lover betray another? >> we were hoping that he would contact us and said, hey, i want to tell you the truth. >> when "tangled web" continues. , is about to become your problem. ahh no, come on. i saw you eating poop earlier. hey! my focus is on the road, and that's saving me cash with drivewise. who's the dummy now? whoof!

confession from the suspect michael minor. however she didn't believe he acted alone. her theory? danielle dreher was the mastermind behind the crime. but she would need evidence to prove it. here is andrea canning. of all the homicides karen fraivillig has prosecuted, she found the case of sam dreher's murder especially frustrating. >> it's hard to remain unemotional in a murder. in the murder of an innocent person who did nothing except fall in love with another woman. >> michael minor may have shot sam, but prosecutor fraivillig believed danielle manipulated him to do it, and that her motive was more than just money. >> i think there was a financial motive, certainly. probably, the most overarching motive was just jealousy. despite the fact that she was conducting an affair of her own, i think that she was just

completely enraged that sam started stepping out on her as well. >> but in order to prove that in court, fraivillig felt she would need something she didn't yet have -- a statement from michael saying danielle acted as his accomplice. so she waited, thinking time would compel him to come forward and admit danielle was involved. he never did. michael maintained danielle played no role in sam's murder. was this possibly a twisted act of chivalry? >> i think that certainly one of his motivations, if not his sole motivation, was trying to protect the woman that he loved. >> did you say to him, why are you protecting her? >> yes. and he said, i'm not. he said, i'm not protecting her. >> we were hoping he would contact us through his lawyers and said, hey, i want to tell you the truth. i want to tell you what part she had in it.

that never happened. >> 2 1/2 years after shooting sam, michael minor agreed to plead guilty to second degree murder. >> and it will live with me forever, and it will haunt me forever. >> reporter: in exchange for his plea, michael received a sentence of 30 years. >> i would not give him anything less than that. i mean, he pulled the trigger. and he didn't pull it once. he pulled it four times. >> i was glad that he was going to jail. michael minor didn't just kill our brother. he has mortally wounded our entire family. >> michael minor never wavered in his statement that he acted alone. in the end, prosecutor fraivillig felt she didn't have enough evidence to charge danielle as michael's accomplice. >> i cannot just charge someone based upon my speculations, the family's beliefs and even the ugliness of these text messages is not enough unless i can show that there was a conspiracy. michael minor never gave me that information. >> what is your gut telling you, that danielle was indirectly involved, directly

involved or -- >> she wasn't involved. >> had no part in this whatsoever? >> she wasn't involved in that homicide. >> news of the decision not to prosecute danielle for sam's murder made sam's sister, cindy, furious. >> do i think it's a tough case? yes, absolutely. but you know what? their job is not to prosecute cases that are easy. their job is to prosecute criminals. >> but just when everyone thought danielle was free and clear, prosecutor fraivillig said not so fast. remember michael minor's videotaped break-in of dianne mcknight's apartment? the prosecutor believed danielle not only helped plan the break-in, but she also instructed michael to steal some of dianne's possessions. danielle was charged with burglary and theft. at trial, the defense argued danielle never asked michael to steal anything. the jury didn't agree. she was found guilty as charged and sentenced to three years in prison and was released in february 2018.

>> this was a very satisfying verdict, to see the woman be punished for her actions. >> is the murder of sam dreher an open case or a closed case? >> no. it's a closed case. >> but not for cindy, who continues to mourn the loss of her brother. she keeps his uniform close by for comfort and, with it, a lifetime of memories. >> he was loving. he was caring. he was the peacemaker. he was always doing for others. he was just sweet. >> cindy once felt the same way about her sister-in-law danielle. now there's bad blood between the two. cindy fought danielle in court over benefits from sam's life insurance. they ultimately reached a confidential settlement. cindy also keeps a watchful eye on danielle. according to cindy, danielle was dating another man before she went to prison. >> she was living with a firefighter, as a matter of fact. one of my brother's supposed

fire brothers. >> what's your advice >> watch your back, you know. the last two guys involved with danielle, one's dead, one's in prison. >> as for dianne, she's now left to reflect on a life with sam that could have been. did you two talk about marriage? >> yes. >> and was that in the cards? >> oh, absolutely. >> did you ever feel like i'm being punished for having this affair? >> oh, yes. i might have said those exact words myself. >> it all started in a club with an innocent conversation. >> uh-huh. >> was it all worth it, falling in love with sam? >> i would never change having met sam. >> was he the one? >> he was the one. without a doubt. he still is the one.

>> that's all for this edition of "dateline extra." i'm craig melvin. thank you for watch iing. eye. i'm craig melvin. >> i'm natalie morales. >> this is "dateline." it was a small new year's eve party. we took off and then shortly after saw the police car. my gut was telling my feet to run back to that house. this can't be happening. >> when the party ended, the mystery began. >> it was just crazy. i didn't understand what was happening and why. >> his wife, the hostess, had seemed fine all night. then -- >> heap me
