when jr and her had no more contact with each other. and she totally focused on dave. >> detectives knew that the whole time knew, that she had been feuding with dave and rosemary over visitation with jordan. pat said the reason that marilyn asked her friend renee with her to drop jordan off. is that she filled a confrontation with dave. >> she felt there was safety in number. >> she recalls an earlier issue when she was on the phone with marilyn, and dave showed up unannounced at her house. >> she let him in the house. which just blew me away. but she wanted him to feel better. having jordan over there. so he could say, this is nice. not dangerous. i'm not planning on taking off. >> but pat said, the visit turned tense. >> she showed him, through the house and took him towards a little bedroom that is just off to the left there. and she said, that's a gun laying there. i won't be as easily taken as linda was. >> marilyn warned everyone around her, that if anything

happened to her. there was one person that they should look at. this is a letter that she wrote to the sheriff's department in february of 2003. shortly after she won visitation case. just months before she was murdered. >> this is just to let you know that if i should suddenly disappear, that i am not on vacation as they've told jordan linda was. i hope you keep this on file somewhere, because dave has now lost some major control. and he's having a hard time with that. >> she was nervous, and she was scared of david watson. >> now, marilyn was dead. detectives couldn't dismiss the strange coincidence of two tragedies happening at the same place, to the same family. >> how often are a mother and daughter killed at the same house, three years apart? that does not happen. >> when linda went missing, two men were on the investigators radar. first, her ex boyfriend jr. with whom she had a tumultuous

relationship. jr insisted that he was at his house the night that marilyn and renee were murdered. and his alibi checked out. plus, said detective kelly anderson. >> there is nothing evidentiary at the scene that would indicate that jr had any involvement. and he doesn't even match the physical description of the person, the eyewitness site at the scene running away. >> but then there was linda's ex husband, david. he to of course had an alibi. he said he was home that night of the murder and his wife backed him up. rosemary had an alibi to. she had been at home with the kids, when marilyn dropped jordan off. >> ever look at morals mary as a coconspirator here possibly? >> she had custody of the child to. they could've been in on it together? >> sure. but just because she is who she is, doesn't mean she's excluded as being looked at. obviously, she is not the man running from the scene. we know that.

watson carried the knowledge. very down deep. it festered. eight away at her. >> if i never said a word to anybody, how do i look my daughter in the eye? and live the rest of my life? knowing what i know. and keeping that. >> rosemary said that the seeds of this dark secret first took root in august of 2000. the night linda disappeared. she of course had been her husband's alibi. told investigators that he was home with her all night. but she told us that that wasn't entirely true. in the middle of the night, she said, she actually woke up. >> and dave was not in bed. and i got up and i walked through the house and i did not see him. and i went and i laid back down. i fell back asleep. >> sometime later, she said, she woke up again. >> and he was not in bed with me again. and i was looking for him, and through the house, peeking out

into the backyard. and then i saw him. >> where was he? >> he was standing at the back of his deep. i could see him through our kitchen window. he appeared to be, he looked as though he was just cleaning out the back of his deep. >> and then he comes? and >> he does come in. and he said i want for a walk. and i asked him if he was okay. and he said yeah, i just need to clear my head. >> does that make sense to you? >> it didn't make sense to me. ida had no reason to doubt him at all. none. >> and then, rosemary said, dave handed her something. >> he actually handed me a box of latex gloves. and said, put these away. which, you know, i didn't think anything of it at the moment. >> this is your new husband, you're in love with? >> absolutely. >> you don't know all his habits? >> no. still learning. >> and wake up and talk to the birds? you don't know right? >> he was an early riser. >> so when investigators showed up and asked where dave had been the night that linda disappeared. >> i didn't mean to lie. that wasn't my intent.

was to lie to lot enforcement. >> did you say that dave is in a jam? you're gonna cover for him? >> i said i love my husband. he went for a walk. it looks really bad, and very suspicious that he went for a walk. now suddenly all this is happening. he said i'm home, and i'm like. he's home. >> so no walk. he was home all night. that was her story and she stuck with it. although, privately, she said. she couldn't help but turn things over in her mind. and at one point, even confronted her husband. >> what i said was please tell me that you are not involved. that nothing, that this has nothing to do with you. >> what do they say? >> i didn't do anything. and that was enough for me. and i said, okay. >> and so, three years past. rosemary gave birth to her son. adopted jordan. and battled over visitation rights with marilyn. and then on may 8th, 2003.

the investigators were at the door again. maryland and renee had been shot. where they asked, had dave been about 8:30 that night? dave and rosemary as we know said he had been at home. but, the truth? >> at that moment. rosemary. was dave home? >> dave was not home. >> according to rosemary, dave did not get home until after jordan was already talked into bed. that sometime after 9 pm. >> and he walked in. and, i saw his four face. and that is something that nobody will ever take away from me. >> tell me. >> panicked! which panicked me. and quite as a ghost. sweating. his eyes were huge. and just instantly, it scared me. to where the first thing, the very first thing i said to him was what's wrong? and he didn't say anything. and i said dave, what is wrong? and he didn't say anything. and he leans down, kisses

jordan. and shut off the light. and he kind of pulled me around the corner. and i kept asking him, what is wrong. what is going on? there was a lot of what the hell is happening? he started to take off his clothes in the kitchen. and quickly. and he said watch those. i'm getting in the shower. and he made a beeline for the shower. >> and then when the investigator showed up at the door? >> he clearly stated. been home. >> and they ask you directly, was dave? here >> yes. >> you told him a lie? >> i absolutely did. i follow dave's lead. >> but rosemary said her insides turned. >> it really took a took on me, physically and mentally. just everything terrified me. gave terrified me, he handed me knowledge that i didn't want to know. i didn't ask for it. i didn't want it. and he left me there, holding it. and it became a very heavy

burden. >> is this where your marriage becomes unraveled with dave? >> it definitely starts. there it never was esteem after that. it never was the same. >> the dominoes, said rosemary, quickly began to fall. dave's behavior changed. and he had an affair. months after maryland's murder, rosemary confronted him again. >> and i said, i think you killed three women. and his response to me was. are you afraid of me? >> that's how he responded? to that confrontational question? >> that's how he responded to me. there was no, there was never any reassurance. >> i would've done nothing like that. none of that. >> there was nothing. it was are you afraid of me? and you trust me? dave. >> dave she said, blame her. for the suspicion that it fallen upon him. >> he had made statements saying. people are saying that your telling this town that i did it. and what he told me was, you need to shut your mouth. and what i said was, i am your

alibi! and that was a quote. and it was kind of left at that. >> a few years later, rosemary and dave were divorced. and it was in the midst of an argument over childcare arrangements, that rosemary said that everything came to the surface. >> the moment that it hit me, was when i said please don't make me take you back to court. and when i said that, he took off his sunglasses and said don't f with me rosemary. and it did. it scared me. >> did you feel scared for your life at that point? >> i. >> linda, marilyn, i might be next here. what's going on this guy. >> there was a moment yes, i did. >> after the confrontation. she confided in her best friend. who urged her to call the sheriff's department. she met with an investigator. >> and i told him straight out, i said i lied. both times. and i think as we went through

a conversation, you, know it kind of ended with i never believed you anyway. >> but the alibi had gone up in smoke? >> yes. and there was no turning back. it was the truth. >> detectives kept rosemary's confession secret as they slowly build their case against dave. when he went on trial, she would be the star witness. but, by her own admission, rosemary had lied for years. why would a jury believe her now? >> coming up! >> did any of that get to you? >> no. knowing my father. i really don't feel he would go as far as the killer woman. >> a daughter defense her father. and explain to yourself. >> being a seven year old, i probably wasn't very clear. >> and an ex wife takes the stand. >> i knew that i could not hold this in any longer. >> when dateline continues!

when dateline continues malignant rhabdoid t umor on the spine. we had been going to doctors here in louisiana for about three weeks prior, and then we got sent to shreveport, and they did a scan and found that it was a tumor, and they sent us straight to st. jude. when i received the diagnosis with my daughter, my hope was gone. but when you get there, everyone's like, hey, we've got your back. we're not going to give up. and when you see other people not giving up on your child, that makes all the difference in the world. when we first made it to st. jude, my baby couldn't sit up on her own at all. the tumor had pressed up against her spine to the point where it basically paralyzed her. she couldn't feel her feet or anything like that. she went literally five, six months without walking. and just to see her start to make those steps after treatment. take your time, one step at a time. child: take my time.

spends his weekends about as far away from a courtroom as one can get. >> i need a way to get it out of my head. like climbing? you have to be completely voters in the moment. not worried about you, your, life you're self. >> all the chatter in your head stops? >> it's liberating. it scratches my head so i can go back and do the next case. >> and there were so many cases, like the one he took on in 2014. tucson fire captain, david what, an accused of killing three women. >> this is the pinnacle for a prosecutor to take the challenge, make the challenge almost him insurmountable. make it big. and overcome it. >> him and his counsel felt they were up to the challenge. >> we had no doubt, no doubt

that david watson killed the three women. we just wanted a chance to put it in front of a jury. >> that chance came in october of 2016. >> two women battled david dwayne watson for control, and custody, of course jordan watson. two women who are both dead. >> the prosecution called jordan, who still believed her dad was the innocence. to testify about that interview that she gave at age seven. >> i said, is that still at his meeting? she says i do not know. >> that is number one cooperation for when rosemary comes forward later and says that david watson was not home. >> being a seven year old, i probably wasn't very clear. of course. but, i have no memory of that. at all. >> and she told us, her relationship with rosemary was never the same. after rosemary started expressing doubts about dave. >> did any of that get to you

jordan? did you start to turn these ideas running your head? or is there something to this? >> she really tried, i'll give her that but no, knowing my father i really don't feel good to go as far as to kill a woman. >> don't let the helpful, fire kept an image full uses the ross occasion. dave's training, they, said was exactly why he is capable of killing three women. >> what is a paramedic too? responds to bloody scenes. they remain calm in certain circumstances and this was david watson's key attribute. >> that, along with a mountain of other circumstantial evidence. the money clip. the nine millimeter shell casings, dave statements to his friends. the horse right near silver bell in 2007. all pointed to a guilty man, according to the state. >> you prove this case by 1000 cuts. 1000 little cuts. and there is not going to be the one aha moment that comes

down that solves this case. >> wrong, said the defense. there wasn't an aha moment because dave did not do it. representing dave watson, husband and wife legal team, michael story and rich asha ray. much like their prosecution counterparts, not one to shy away from the challenge. >> this was the most monstrous undertaking that we've ever had in our careers together. >> according to the defense, there were any number of reasons why linda, marilyn, and renee died. reasons that had nothing to do with dave watson. >> as much as the state says, they want some dave watson. you're going to see it going in another avenue. of people, and circumstance. >> other avenues? such a suicide. whether linda's. >> with the drinking, the ex-boyfriend testifying against her, losing her job. >> or even rene's. the defense said that maryland's friend had once discuss suicide. and they suggested that she may have chosen an unusual method. >> we all know that insurance

won't pay if you commit suicide. >> is your theory, or at least you're willing to consider that rene, a friend, has somehow commissioned her own murder? >> that was something that we had thrown out in theory. >> what movie or you? see >> there is some crazy people out there. >> then there was this idea that maybe linda's ex boyfriend was the culprit here. dna consistent with jr and not dave, was found on a trash bag that had linda's blood on it. although jr himself testified, nothing surprising about that. he said he had been helping linda fix of her house. and then he had nothing to hide. >> i have corroborated with the sheriff's department in their investigation 100 and 10%. >> and remember how linda went out drinking with her cousin a few days before she disappeared? the saloon isn't far from a rural part of town called green acres. a witness testified that she had heard someone in green acres talk about moving linda

watson's body. >> she reports that that potty was being moved to silver bell road. and that is within four miles of where the girlfriend is? >> so the geography matches. >> it fits it. >> so linda might have gotten into a pick up truck? >> right. >> they said -- had written out near the civil bell line before. but as for that specific trip, on new years eve 2007. >> i don't think that happens. >> you don't think he went? there >> the defense highlighted that while pima county sheriff's investigators provided a print out of the coordinates, they never save the raw data. and, what about that money clip with the and the sholes dtw? the defense theorize that maybe marilyn's family planted it. >> we have our theories that this family was looking for a scapegoat. and they believed that dave did it. so they planted the money clip. >> ludicrous, said maryland sisters. >> it made me -- if i was gonna do something

that stupid, i would've taken it from the crime scene. why would i put it here in the back? >> the defense also pointed out that there was no probable link between the ruger that day once owned, and the mare magnet that killed rene. >> it wasn't conclusive that it was a. >> but at the end of the day, the prosecution and the defense agreed. the case hinged on the believability of one witness. rosemary watson. >> if you don't believe rosemary, you don't have a case. >> it just chilled me to the bone. >> rosemary explain to the jury why she decided to come forward in 2007. >> and i knew that i could not hold this in any longer. because. three women lost their lives. their lives matter. >> and then there was a critical detail. rosemary craig testified that on the same day that -- disappeared, they found his own mother was planning to testify

on linda's behalf at the upcoming testify hearing. >> he -- >> did he succeed? >> now. she was very adamant about testifying for linda. >> the prosecution said, everything was coming to a head that night. >> it's about control. and that is a man who seething inside. the night that he finds out that he can't get his mother, not to testify against him. and his own mother. and that's how vicious it had to be done. >> so you see the fuse being let here? >> yeah. i mean. i don't know when the fuse was lit, but it was getting down close to the explosives that that night. >> but according to the defense, rosemary watson was just not critical. >> she was a liar, back when she gave the alibis. or she's a liar when she's giving the -- >> so the jurors? pickett >> no they shouldn't pick up because they should say she doesn't know what they believe. >> so you have this story that

you're calling ally now? right? >> it is a lie. >> and in the last seven years is the truth, right? >> i came forward. and told the truth. >> i understand they are completely different versions of that night. yes? >> they are. >> one of them is a complete lie? yes? >> yes. >> the defense in a nutshell, help have no fury like a woman scorned. >> so she's wanting to stick it to her ex? that's your theory? >> exactly right. >> appointed defense drove home in closing arguments. >> she's a liar! when you have a blatant, full face liar like that. you cannot consider the testimony. you have to throw it out. >> the prosecution argued that the jury should believe rosemary. and not the wild theories floated by the defense. >> the truth is, folks, august of 2000, that man killed linda lawton.

in 2003, that man killed marilyn cox. and killed rene farnsworth. there is no other evidence, based in reason, to any other answer than that. >> and now, it was in the hands of 12 jurors. and right before thanksgiving, they surprised everyone. coming up! >> we the jury to find the defendant, what. >> after so many years, and one last twist. a verdict! >> there is no way. no way beyond a reasonable doubt you could think i would've done any of this. >> we were all pretty positive that, this is gonna be over. he's gonna come home. >> my hands were sweating. i was nervous. because i know the victims families from behind me. and this is everything to them. >> when dateline continues! n dateline continues a cold is not just a cold.

coricidin is the #1 doctor recommended cold and flu brand. specially designed for people with high blood pressure. be there for life's best moments. jordan watson firmly believe trust coricidin.

that her father was innocent. and expected to have him home for thanksgiving. >> we were all pretty positive that this is going to be over. he's going to come home. >> then three days after deliberations began, the jury came back but it wasn't what anyone expected. >> was there any possibility that the jury would want to consider further -- ? >> not at this time. now. >> the jury was hung. gabe watson soon learned that he had just been a few votes shy of walking out of jail a free man. >> attended to acquittal in the case of linda. and 8 to 4 for acquittal in the case of marilyn and renee. >> yeah, it brought tears in my eyes that it was even a hung jury. >> the defense contain their excitement, and brace

themselves. >> the only conviction is a when. but it's a hollow win in that the state can come right back and target again. >> which is exactly what happened. the real trial began on january 25th of 2017, the prosecution led with its star witness. >> the state calls rosemary watson. >> but this time they retool their case of it. >> i read the transcripts from the first trial and one thing that i saw too much of was me speaking. and so, i doubled down on the idea that the jury had to hear from rosemary. so i got out of the way, i asked shorter questions. >> anything unusual happened that night? >> yes. i woke up in the middle of the night. and they was not there. >> the second time around was different for rosemary to. >> now i'm a little mad, not only is he lying, he is making me out to be just a bold faced liar. she >> testified about how she had lied to protect her family. and about what coming forward

with the truth had cost her. >> does jordan call you mom anymore? >> she doesn't speak to me very often anymore. >> is that since this case? >> correct. >> the prosecution called jordan next, so the jury could hear how her interview at age seven, backed up rosemary's claim that dave was not home. not so fast, said the defense. >> i can only imagine if my seven year old was interviewed about a key fact that would decide a guy's life. it would be scary. >> they maintain that day was home the night in question. he didn't kill anyone, they said. they once again considered multiple other scenarios of what could've happened to linda. she died by suicide, she was murdered by a mysterious killer from green acres, or by the one suspect who stood out for the defense. >> if not dave watson, then who? >> it would be carl. >> carl barton junior, jr. nonsense, said the prosecution. >> there is no evidence linking jr to any of these three

murders. none. >> after seven weeks of testimony, days faith was once again in the hands of a jury. >> we were getting indications from questions out of the jury that they might actually go into the next week. i was thinking that they were pretty hung. >> but then after a day and a half of deliberations, the jury buzzed with a verdict. it was st. patrick's day. detective kelly anderson hoped lucky would be on his side. >> my hands were sweating. i was nervous. i'm nervous over every verdict. but i'm more nervous now. and it is because i know the victims families are behind me. and this is everything to them. >> the stakes were high for him personally to. he was retiring. and this was his last homicide case. the moment of truth, when the one that had taken 17 years to arrive was finally upon them. >> we the jury, defend the defendant. david dwyane watson, guilty of the offense of second-degree war murder with the watson.

>> when he said linda. i didn't even have to listen to the rest of it. we know if we got him for linda, the other two was an automatic win. >> david watson. father, friend, and fire captain. was also convicted for the first degree murders of marilyn and renee. the loyal friend, who didn't even play a real role in her own murder case. >> she was forgotten a lot. but my mom was kind of, make,, mild quiet person in the back. and she's kind of just go with the flow. and she was always there for anybody that needed everything. >> jordan was heartbroken. dave says that he could not believe it. >> i would've never imagined that in millionaires. from what was being presented in court? i would've thought, there is no way. no way beyond a reasonable doubt that you can think of. would've done anything with this. >> did you go over to linda's house? of? dr. kill? her dropper in the washer with a silver bell? >> no. not at all. >> did you get a nine

millimeter, a ruger, did you put on a hoodie and go kill marilyn and her friend on the driveway range? point-blank range? >> nope. >> but the jury believed otherwise. and the man who made a career out of saving lines, is doing time for taking one. he was sentenced to life in prison. >> is it a nice, sentimental ending? for your career as a homicide detective? >> it's bittersweet. it's a little bit that makes me want to do it again. >> the fault is three cases lighter now. and the families of linda, maryland, and rene have some measure of closure. thanks to an enemy turned ally. >> one of the ironies here is that you ended up delivering for women that you had been fighting earlier in your life? you delivered for linda. you delivered for maryland and her friend renee. >> ultimately i did, didn't i? >> she hopes jordan will one day come to understand that. >> feet are directly now. >> everything that i didn't

want for her has happened. and so speaking to her, i guess the only thing that i could say, is that i'm sorry. but i am always here for her. >> we are sorry but you say that you also did the right thing. >> i did do the right thing. if this was me? and i died fighting for justice for my daughter, i would hope that everybody would just tell the truth. >> but the truth, sometimes as murky and hard to see, as the desert with night closing in. what with all of those secrets, and old bone scattered about. unchanging. >> i'm craig melvin. >> and i'm natalie morales. >> and this is "dateline." >> i was shocked. things just didn't add up. >> it was the last place you would expect to find a gruesome crime scene. quiet neighborhood. a lovely home.
