hard to explain though, given the turmoil of that day. but then she remembered how after the face left, michele's doctor described hydro code on, promises the, in and mbn. but her father them to prescribe percocet and valium as well. to alexis, that seemed like too much medication. >> he told the plastic surgeon how much in that occasion to describe to her. >> isn't it the surgeon he usually makes? that >> yes. it was strange. >> stranger than, what happened. after michelle died. when alexis went looking for those pills. after that about them. >> where were they? >> he told me that, oh, the police must have taken them. but i later found out that he had my brother and his girlfriend flush them down to the toilet, and throw the bottles away. and the reason for that, it was that having her medication

there. >> some very unpleasant thoughts in alexis's head. and then there was the business of the funeral. >> my father was very adamant to have the funeral right away. >> and at the funeral, says his daughters. he talked less about his wife of nearly 30 years, then he did about himself. >> lord, i thought i was your boy. lord, i thought i was doing a good job. lord are you there? as the hours pass last night, the answer came to me. i've had such a good life. >> alexis and rachel were appalled by that. and angry. but even as they pondered what to do with their blossoming suspicion, the autopsy results were released. and to then police chief michael smith, the result seemed crystal clear. >> the medical examiner's report indicated that michele had died of myocarditis and hypertension and listed it as a natural cause of death.

>> in other words, classic heart disease. a cause of death all too common around women michelle's age. especially someone with blood pressure that is high. the doctors, it determined, whereas not based on any possible flat. they were therapeutic level. as far as the state of utah was concerned, the matter was coast. >> the matter in the state of utah, is the ultimate say when it comes to the cause in the manner of death. >> the tension in the mcneil family worsened. maher won an alexis disagreed on how to care for the younger children. now that michele was gone. >> he kept saying, i'm gonna need a nanny. i can't take care of these kids myself. >> coming up! martin mcneill hires help. >> oh i found the perfect nanny. and i said, dad what's her name? he said oh it's chilean. i said dad, i know that woman. >> when dateline continues!

there are many kinds of grief. alexis and rachel were struggling with the angry kind. not angry with their mother for day. no. it was what grew from the suspicion they felt. that their father was hiding something very bad. but still, they wore practical models to deal with. such as who should care for the

smaller mcneill children. alexis returned to medical school, so rachael volunteered. when there father insisted they find a nanny instead. right away. >> he asked me, demanded that we go to the temple to pray for having and manny. which is very strange, because my father is not very spiritual at all. >> and they're outside the temple. they were approached by a mysterious brunette. >> she said oh, i was at the funeral and i am so sorry for your loss. and my father said, oh, i'm sorry. i know i know uber what is your name? >> and she said my name is julian. and my father said oh, okay. >> about a week after that encounter, martin hired that friendly, sympathetic woman. and told his daughters. >> oh i found the perfect nanny. i found somebody who's going to be great. and, i said dad what is her name? and he said, oh it's chilly in.

i think it's gillian. >> the name, julian, didn't mean anything to rachael. but alexis? >> i said dad. i know that women. i know mom was concerned you are having affair with her. >> an affair? well. yes. or at least, before michele died, that is certainly what she suspected. so worried about it, she asked alexis to help to find out for sure. >> my mom confided in me about everything. all of her feelings, her concerns. and so, i took his cell phone and was able to download his password, and we did see a number that my dad had been calling quite a few times. >> you hacked into his phone? >> yeah. we call the number. and a woman answered. and then hung up right away. so i paid for an online search. and it came up with a name. and it was gypsy jillian willis. >> gypsy julian willis?

>> yeah we thought maybe it was a stripper? but anyways, my mom, with that information, with the ladies name went to my dad and confronted him. >> martin denied everything. settle excess. and then the very next day he made a curious suggestion. >> my father came to my mom and told her that she needs a facelift. >> that is, i mean, lots of women decided they want faceless but. when their husband comes and says, you need one? >> yeah. it was really out of the blue. >> the face left. that preceded michel's death. and now, here was gypsy julian. martin's choice for a live in nanny. someone he just happened to find. >> so she got the job. she moved into the house, and this was just a couple weeks after my mom's death. >> martin's daughter was furious. they wanted to know what other secrets their father had been

keeping. they expanded their investigation. >> my sister put a blog up. and was asking anyone with any information about my father to contact her. we discovered that he had had so many different affairs. there was a lot of different things that came out. >> with her and linda they took all of their information that they gathered on martin, and brought it to the authorities. >> pushing and pushing to get them to investigate. >> the local police had never of investigated michel's death at a crime. not since the very first day. and remember the coroner's report? her death was caused by heart disease. >> for us to be able to overcome something like and medical examiners office that said she died of natural causes, is a huge task. >> but the women were relentless. they met with jeff, and doug whitney. who worked for the county attorney. >> you took them seriously right off the top? the daughters? >> not really. >> but then they started to looks at some of the evidence the amateur sleuths had

gathered. not evidence of murder, but still. >> they started to challenge a lot of things that her father, who he, was when he was, when he was doing. and so we thought, you know what? i would like to find out if he really is a doctor. >> yes, martin did have a medical degree. but. >> he fraudulently got in some medical school? >> yes. >> after faking the results from college? >> he took somebody else's marks because there was a different date of graduation, a different date of test. >> and it got deeper. before he faked his college transcripts, he was convicted of forging checks. now, said the investigators, the respective doctor was looking anything but respectable. >> it tells me that this is not the guy that goes to church every sunday with his family. >> so there's two martin make meals? >> there's two of them. >> still, -- >> but martin starters? they went to their fathers list

of offenses. the fraud, the infidelity. how they encouraged his mother to have surgery, and take drugs afterwards. and they were certain, their father killed their mother. >> he betrayed us to the very core. i mean, everything that we thought in our life is just all shattered. >> it's all a sham? >> it really is. it's been a whole sham. >> but not everyone in the family felt that way. damien, mountains only son, stuck by his father. >> he had a hard time after my mom died. i had talked to him about my concerns and, he didn't want to believe that my father was capable of killing my mom. >> but alexis's conviction was absolute. every time she set foot in her parents home, only one thought went through her mind. >> he's already killed her. >> and yet? there was still no hard evidence that martin had killed michelle. almost two years went by,

martin and gypsy still carrying on in plain sight. but then, in january 2009,? >> certainly they're both arrested? >> yes. >> but not for what people might have thought. >> no, no. >> coming up! two lovers cook up a secret crime. >> she soul gisele's identity? >> for gypsy. >> when dateline continues! teline continues you said you'd never get a dog. you said you'd never do a lot of things. but you never knew all the things a dog could do for you.

but shocking nonetheless. >> it's gisele! >> it all started when martin sent his 16 years old daughter gisele to ukraine to visit her biological sister. >> gisele called my daughters phone. and then they started talking and gisele started crying and told her story, that she got left there. >> abandoned basically? >> right. >> why would he do that? well, a bit more digging reveal that martin and gypsy had cooked up a scheme, and it involved taking over daughter chiseled social security number. >> she stole the social security? >> for gypsy. >> yes gypsy, who emerged, was financially challenged. the new forged a density wiped her that's away. it also gave her a brand-new name. jillian mcneill. but the lies did not end there.

suicide, january 2010. >> he was such a wonderful guy. >> but, the murder investigation continued. picked up steam in fact. the two investigators the briefed gypsy in prison. >> that was a treasure trove of information that she gave us. >> she confirmed that chance meeting at the temple with rachel was a setup, a ruse together into the house after michelle was gone. how long had she and martin been planning it? >> i said so, you stayed since that meeting. this and when did you script it? was it during the funeral, before the death? >> so? >> no comment. >> the investigators went back to the prosecutor. over and over to urge him to charge margin with murder. but. >> one of the prosecutor say with to you? >> see this medical examiner's

report? >> death of natural? causes >> that's right. >> there was a new medical examiner. they showed him the report. the file, the and for fraud. >> i said, these reports are scanned it. you cannot scan the support, just read this month. and he did, and he goes, i think i'm in a look at the steeper. >> after his review, the m e did make one small change. in the manner of death. from manner of death natural, to undetermined. but it hardly broke the case wide open. >> he refused to call it a homicide. >> sure. >> absolutely. >> but mcneill was released from credible prison. so in 2012, martin mcneill was once again a free man. he turned his time for fraud. and we spoke to him that -- >> he was a free man. how did that make you feel? >> very scared. >> you've been the chief

accuser all these years? >> yeah. i'm not concerned. i'm not only concerned for my family, but anyone who comes into contact with my father because i know he is a dangerous man. >> investigators agreed. but the prosecutor wanted more. something that they could take to court. >> show me how she died. show me how she died. >> i said, i believe i know how she died but i can't prove it yet. >> and then? that one little detail. jumped out and said, look at me! >> the time that came to me is when we heard from the hospices and emt to guys when she threw out water. >> if michelle threw up water when the emts did cpr, that meant that martin, the doctor, had not done it properly. if at all. >> okay, do you know how to do cpr? >> i'm doing it. >> and with that, all of the circumstantial bits seemed to line up and support the idea of a planned murder.

a plot that began after martin took up with pepsi. >> his wife finds concrete evidence that he is doing it. he is trapped. why do i do? i can't lose my good name, because i'm lose my job, i'm not lose my reputation, and lose everything else. so what is it here? >> drugs are in drowns her they now believe. and finally, the prosecutor agreed. so in august 2012, martin's daughter sat in a utah courtroom. holding up pictures of their dead mother. as their father appeared in court on charges of first degree murder. >> if she hadn't pushed, if she hadn't started making those calls. with the have gone anywhere? >> i don't think it would've come to me. >> so they would've just. >> they probably would've close it out as unfounded. >> now, the family drama would play out for a jury. but the outcome? it at that point, it was far

laughing, smiling. again remarking that he was going to have to get used to the life of the bachelor. >> house callous, said the prosecutor. but as for evidence that he murdered her? the autopsy said the heart disease was the cause of death. not murder. >> this case is a puzzle piece with many pieces. >> she is unconscious? >> she's unconscious. she's underwater. >> the first piece they said, was martin's behavior during that 9-1-1 call. he seemed angry. he hung up on the operator. >> okay, do you know how to do cpr? >> i'm doing it! >> okay. to not hang. >> first responders had trouble finding the house. and when they finally did arrive, the police said martin was acting so radically, it made them nervous. >> i was concerned about my safety, actually. >> and while martin, the doctor, was performing cpr. >> he was kind of yelling at her. why did you do this? why did you do? this and then he struck her in

the chest with one of her hands. but >> when the police took over, you remember. >> she dispels 3 to 4 cups of water. >> and what would have happened since he would've done cpr? she would've already expelled? that >> i believe so. >> how mutton said he found his wife hidden in the tub. the legs over the edge? prosecutors show how'd his account differed from every other witness. even his six-year-old daughter eta. this is the police interview with eta recorded in 2008. >> was she all the way in the bathtub or just in the bathtub? >> all the way. >> please raise your white hand and take an oath. >> and then prosecutors called to the stand the woman at the center of it all. the woman who so captivated martin. the mistress. and, they said. the motive. >> my name is gypsy willis. >> gypsy told the story of an online relationship turned

2007. the day michele was buried. and remember, gypsy had testified as part of a plea deal. didn't want to. >> she minimize their relationship, but i think in so doing. the jury saw that. >> but just to be sure, the prosecutor had gypsy read love lovers that martin wrote to her from a prison. >> i love and miss you every minute. i can think of nothing but how lovely you are. >> so gypsy, said the prosecutor, was martin's motive for murder. that is, if it was a murder. and, if it was, was she involved? >> in light of all this information. are you telling us that you don't know anything more about michelle's death? >> that is correct. >> do you believe she had something to do with it? >> well as far as the actual death, we have no evidence to show that she did. as far as being a coconspirator, talking about it? that speaks for itself.

>> and so, gypsy star turned was over. outside the court, she said, she was so overwhelmed by all the attention. >> testifying here today? >> being in court at all. i've never had more than a speeding ticket. >> of course, as we, know that wasn't even close to being true. and back in the courtroom, the jury was finding out that gypsy wasn't martin's first mistress. >> is it fair to say that you and dr. mcneill began an affair? >> yes. >> this woman said that she can doodled with martin. before he took up with gypsy. and their pillow top, she told the jury, including what's sounded like, a prescription for murder. >> did martin ever describe a process of making someone have a heart attack? >> yes. >> specifically what did he tell you? >> there is something that you can give someone that is natural so that it is not detectable after they have a

forward. >> for six years, alexis summers had been the strongest, most persistent voice arguing that her father murdered her mother. prosecutor jack. >> her testimony was huge. >> under oath, alexis told the same story that she told us. >> why were you seeking information as to your mother's death? >> because i believed my father killed her. >> but now, the defense was going to try to prove that alexis was wrong. in fact, they were gonna question if there was a murder. at all. and they would start by using some of the accusing daughter's own words. remember alexis's claim that her mother was feeling fine? just before she died?

well it turns out that wasn't what she said at her mother's funeral. >> the last time i spoke to my mom. she was happy. she wasn't feeling good. she was feeling a little sick but. >> she was feeling a little sick? that's what you said. right? >> i don't remember her saying that she was feeling a little sick. i remember her being up and getting ready for the day. >> but you remembered it on the day of her funeral. right? three days later. and since that time you said over, and over, and over again that your mother was feeling great. there was no problems on april 11th. >> the indication? if michelle was feeling sick, press before she died, there could be a medical explanation for her death. and, that alexis's memory was flexible. >> i just don't remember her feeling bad at all. >> well, you don't remember accurately in this case right? >> and then the defense honed in on the biggest problem.

here they were prosecuting a man for murder, went according to the states own medical examiner, the cause of death was most likely heart disease. coroner med made it that he never classified michel's death as a homicide. and even his decision to call it undetermined was not exactly based on science. >> you met with the investigators in your office, correct? >> yes that is correct. >> and they were trying to persuade you to change it? >> they gave me an extensive an in-depth conversation on why they thought this was a homicide. >> then the prosecutor took an extra step to hire another -- the defense showed on prosecution that he was no more definitive. >> when you consider all the circumstances of the case, you still conclude that the manner of michele mcneill's death is undetermined?

>> yes sir. >> and remember that water in michelle's lungs? the defense co-counsel randy spencer had an answer for that to. >> michelle was found in the bathtub, and it's very difficult to do cpr in the bathtub. >> so why did he pull it out of the tub? >> he couldn't. barring some god given grant of his superhuman strength, very few people would be able to lift 182-pound person out of the tub in that situation. >> just in that moment, in that scene, whatever he would have done in this character. in that moment, where was the strongest evidence he did not kill her? >> i think the strongest evidence was likely the time of death and where martin was that morning. >> please raise your right hand and be there. >> the defense called witnesses, that's they said they saw martin right before she collapsed in the bathtub. in other, words she wasn't there.

couldn't kill her. >> this is the six years old kindergarten teacher. >> and mr. mcneill kick picked her up that day? >> yes. >> so he was there between 11:30 and 11:35 to pick up? >> yes. >> and all of those facts took the closing to put it together. it was aggressive. >> make no doubt, we believe he intentionally, and knowingly, cause the death of his wife. the evidence supports it. the motive is there. the means are there. and the opportunity is there. >> and the defense? had to concede that martin was a cat, and a cheat. but insisted that the prosecution didn't even prove there was a murder. let loan that martinique committed it. >> i assert to you that none of the circumstances that the prosecution submitted is consistent with homicide. they don't rise to the level of beyond a reasonable doubt. >> and then, the jury began

deliberating. they huddled. hour after hour. late into that friday night. midnight came and went. they were still talking. >> the longer the deliberations would go, the more worried i got. >> the quicker the deliberations the better? >> in this particular case, i thought so. because our case with simple. >> then after 11 hours, a verdict. two quick, thought the prosecutor. >> when they were coming back after 11 hours, i was a little bit nervous. >> it was one in the morning, on saturday november 9th, 2013. >> we the jury have reviewed the evidence in the case, and find the defendant, as to count one, murder, guilty. >> that woman, the michele's family couldn't hide the relief. after years of fighting they had gotten what they wanted. what they demanded. but until that moment, martin's defence attorneys believed more than martin himself that he would be acquitted. >> i think martin took it

better than we did. the he's like, i'm okay. and i was thinking, i'm not okay. >> and then, according to the defendant, randy spencer, martin said something quite remarkable. >> this may seem strange but he even respects what's his daughter's dead. not because he killed his wife, but because if they really believe that he killed his wife, he would expect them to advocate for her. so he understands. >> he told you? that >> he did. yeah. >> i'm just so happy he can't hurt anyone else. we miss our mom, we'll never get her back. but that courtroom was full of so many people and who loved my mom. >> you found your family got justice? >> there's justice for my mom today. >> martin mcneill was sentenced to 17 years to life. but he would not serve his time in full. in april 2017, martin died of

soon side. a dark ending for the story of a family that began with so much hope. >> that is all for this edition of dateline. i'm craig melvin, thank you for watching! watching >> thank you for watching. i'm craig melvin. >> and i'm natalie morales. >> and this is "dateline." he's a monster. he's evil. he's pure evil. he is that character in those horror movies. >> he hid in the shadows. a killer in a mask. >> he's clearly a brilliant individual. a brilliantly scary individual. >> his target, a doting young mom. >> she was a gorgeous strawberry blond who loved her son more than anything in the whole world. >> she was so scared. >> he struck once. would he kill again and would she be next? >> we were just so shattered and hurting so bad.
