events that would define a family and a jury. here's keith morrison. >> we know the truth, and we know everything that happened. >> how do we know what we know? >> it's emotionally unsatisfying not to have that answer. >> though it is, even if we've seen something or if we think we have. and that's the question at the heart of the whole puzzle. is this woman right? >> i know what i saw. and i know the conclusion of my story. >> reporter: of course she does. of course she does. so why does this other woman think this? >> she didn't know for sure what she saw. >> reporter: a question, we say, on which all the rest will turn. why don't we begin sneer calamesa, california, riverside county. historic missions, sprawling suburbs creeping out to the rim of mountains, around the eastern flank of los angeles. here is where chris and christie

hall had come to live out their golden years, though they were far from old when it happened, just experienced, with life and each other. >> as far as i can remember, it's always been chris and christie because they were never thought of as separate. they were a unit. >> these are their three daughters. courtney, the eldest, is a teacher. brianna a personal trainer. and ashton, the youngest, here just returned from playing professional volleyball in europe. and all of them, of course, have heard scores of times the story of how their parents met. it was 1978. christie had gone to see a relative at the air force base in nearby san bernardino and quite by chance while she was there encountered a security guard who, to her at least, looked just like elvis. it was blair christopher hall. chris to his friends. >> apparently, she was a little flirty at the gate. >> reporter: in short order chris and christie got married.

she was 17, he 20. and as the girls grew up, they said they never doubted for a single moment the powerful bond of love. their parents with them and with each other. >> i could say we were probably closer with our parents than most children. these are parents that i hoped to one day be. >> reporter: christie, the vivacious glue of the family. chris, her perfect mirror. >> my dad's a little more kicked back, relaxed, and quiet. but they're a perfect balance i think. >> reporter: for years chris hall was a police officer in san bernardino. until he was shot in the line of duty. then he went on to become police chief in two small towns in idaho. then in 2005, anticipating an empty nest and eventual retirement, the halls bought this place back in calamesa, which they loved for its back yard pool and spa. and life in the spring of 2007 seemed to have hit a sweet spot as ashton and brianna remember

their mother telling them. >> we happened to be laying on the bed with her. she just started talking. she's like, i'm just -- i'm so happy that i have you girls and dad. >> it was kind of one of those conversation that's you don't have every day. >> reporter: still, there was work to be done. it was not a new house, could use some remodeling. particularly the bathroom. courtney was still living with her parents as the work began. >> they were going to be doing the tile work and stuff. so we wouldn't have a shower for that day. >> reporter: so shower out of commission, they decided to wake up early, put on their bathing suits, and rinse off in the outdoor spa, before the contractor arrived at 6:45 a.m. it was june 7th, 2007. chris got on first, turned on the spa to warm it up, but then called brianna at her college dorm in san diego. >> there's your wake-up call, babe. get out and go on that run. >> reporter: back at the house courtney dozed through her first

wake-up, while chris and christie made their way out to the spa. just after 6:30 chris looked in on courtney again, second call, then headed back to the spa. life's last normal moments. 6:37 a.m. >> i got up out of bed and i was putting on my robe and i just heard this panicked -- panicked scream from my dad yelling for me. i ran down the hallway to the back porch, and i saw him. he was trying to pull out my mom out of the spa. >> 911, emergency. >> reporter: it was she who dialed 911 as she and her father struggled to lift her mother out of the spa. >> it was the first moments of the worst day of our lives. >> reporter: is it possible for people to understand what it's like to be in that situation? >> i don't think so. to see just both your parents in the worst times that you've ever

seen them. obviously, my mom unconscious and my dad just panicked and for the first time in my life seeing him just that way, not knowing what to do. >> because he was a cop. he was used to dealing with those kinds of things. >> he was a cop. used to dealing with those kinds of things with people that were not his wife. >> reporter: so courtney took charge. after calling 911, she started cpr on her mother, with her father. emt and firefighter eric norwood was the first to respond. >> he just started, "help my wife. oh, my god. help my wife. help my wife." >> reporter: chris hall was kneeling at his wife's side, more in the way than anything, and so hysterical it took a while for the emts to help. >> he it took us a while to get him out of the way. >> he didn't want to leave her. >> reporter: the paramedics worked on christie for 20 minutes. no vital signs. none. >> and no words just to describe the fear and the anxiety.

>> reporter: you're losing your mother, and you're watching her go right in front of you. >> we tried to save her together, and we just couldn't. >> reporter: the ambulance rushed her off to the hospital, where she was declared dead. she had drowned in the family spa. a private family tragedy. except maybe not so private after all. someone was watching. coming up -- >> it was a horrible scream. >> reporter: a witness. but to what? what exactly did she see? >> i don't know. you know, i -- i can't explain what she's saying she saw. >> when "dateline" continues. o, i've learned that when you ask someone in texas if they want "big" savings on car insurance, it's a bit like asking if they want a big hat... ...'scuse me... ...or a big steak... ...or big hair... i think we have our answer.

on the morning of june 7th, 2007, brianna hall was on the road from san diego, driving home from college. to what she didn't know. except that her elder sister courtney had called and it sounded bad. >> she said there was an accident, you need to just, you know, come home right away. >> reporter: it was courtney who eventually broke the news to ashton and brianna. their mother, their father's wife of close to 30 years, was dead. but neither courtney nor chris waited at the house to tell the sisters what happened. or to comfort them. nor did they linger over the body at the hospital. they couldn't. because father and daughter were escorted to separate squad cars and driven to the police station to talk about the accident. >> what was that ride like? >> quiet.

>> i just remember crying the whole time. i couldn't comfort my father. he couldn't comfort me. i was at the station and they said my dad would just be a few more minutes. >> reporter: chris, so frenzied at the scene-h calmed down by then. he was a cop among cops, after all. and he understood, he said, what was necessary, to help them sort out what happened. >> i can't even start to imagine what you're going through. okay? and just -- just you know, it's just a death investigation and we have to do this. okay? >> reporter: happy to help, he said. whatever would get him back home to comfort his daughters as quickly as possible. >> this is going to kill them. they were all so close. >> reporter: chris told investigators what happened, how as courtney slept he and christie were in the spa bathing. >> she got out, went in, went to the bathroom, got some more coffee, tried to wake up courtney. courtney didn't wake up,

apparently. she came back out. >> as christie returned to the spa, said chris, they passed each other on the patio. he went in the house then, he said, stopped by courtney's room to make sure she was awake, then went right back outside and saw his wife floating face down in the spa. he called courtney then, he said, and they began a frantic effort to revive her. >> i could tell we were losing her. >> reporter: from what? a fall? must have been. >> in your gut tell me what you think happened. >> i think that she slipped in. she slipped or something. i don't know. i -- that's the only thing i can think of. >> reporter: but chris apparently hadn't noticed the nasty three-inch laceration on christie's head. and here suddenly the point of the police interview is revealed. >> the gash she has on her head. >> she's got a gash -- >> she's got a huge gash on her head. okay? something like that's not consistent with just falling down. >> reporter: not consistent with just falling down?

why would the police think that? >> yeah, i mean, you've been around for a while. >> i know where you're going. and no, there's nothing -- >> reporter: why in fact was this ex-police chief being questioned at all about the apparently disastrous accident that killed the love of his life? and the answer was right next door. when chris and christie hall took their outdoor bath that morning in june, someone was watching. her. >> i got up at 6:00, got my coffee. >> reporter: lindsay patterson was on leave from her i.t. job in the navy, visiting her mom, who lives just over the back yard wall from the hall house. lindsay was inside, in the bathroom that faced away from the hall house and out onto the street, when she heard a noise. >> it was a horrible scream. it was this -- something is wrong kind of scream. >> reporter: a woman's, she thought? she went outside to tell her mom. >> and i said, "did you hear that scream?" and she said, "yeah, but i think

it's just kids playing in the -- playing in the pool." >> reporter: kids? at 6:00 something in the morning? lindsay walked over to the six-foot brick wall between their yard and the halls'. she stepped on the planter, she said, and looked over the wall. >> at that point i saw a man with his hands -- one hand on top of a woman's head and then one hand on her back. and she was face down in the water. >> like something was going on? >> yeah. that's what i assumed. >> reporter: that is, she thought she was looking at a sex act in progress. >> i don't know why it didn't seem right, but something made me want to look again. >> reporter: 90 seconds she said between her first and second looks. and this time she said she only saw the man in the spa. >> he was leaning back, just relaxed, in the hot tub. but i don't see her. he's got his elbows back, and he's kind of looking around, like nothing. >> reporter: where did the woman go? lindsay told her mom something

seemed strange. >> she again tells me you why stop being nosy, don't worry about it. but it just didn't seem right. it wasn't enough time for her to have gotten out and gone inside the house. >> reporter: so, said lindsay, she went to the wall again. her third and final look. >> at that point he was getting out of the jacuzzi. and he was in a very big rush. she's still nowhere to be seen. the look on his face was almost undescribable. it was almost as if he had just gone into another world. it was scary. >> reporter: it was instinct that told her something was wrong, said lindsay. so she called 911. >> 911. state your emergency. >> i heard a woman screaming. >> reporter: so now, hours and hours later, the detectives confronted chris with lindsay's story. why, they asked, didn't her story match his? >> so am i supposed to believe

the witness is lying? >> i'm not going to say she's lying. she sounds like a truthful kid or whatever. but i don't know. you know. i can't explain what she's saying she saw. >> reporter: so now that question we posed as we began, did lindsay patterson really know what she saw? >> coming up -- >> she didn't see what was really happening. >> what had really happened? there would soon be a turn in the case. >> this was not an accidental drowning. it was purely much more suspicious than

chris and christie hall's three daughters clung together in grief and shock all through the dismal evening hours of that worst of all days, june 7th, 2007. waiting for their father to

return from the police station. and they wondered, why was it taking so long? then the phone rang. and they had their answer. >> you know, broken up words, and he's crying and we're crying. and that was when he said, "they think i hurt mom." i mean, he was very upset. >> reporter: but he didn't sound surprised when he said -- >> no, he was crying. >> he was crying. >> he was very upset. >> reporter: but by the time police investigators were questioning chris, remember, they'd heard from lindsay patterson, and at the station chris's version of events in the spa differed in one crucial detail from what lindsay described seeing that first time she peered over the wall and into the halls' back yard. >> that specifically, me holding her down in there, there's nothing that took place in that jacuzzi that would explain that. there was no sex. there was no -- i don't even think we had any contact while we were in the jacuzzi other

than when i was getting her out of the jacuzzi. >> reporter: but investigators were getting a good look at christie's body and saw wounds that to them suggested a struggle and more than one nasty blow to the head. so the police had to choose which version, chris hall's or lindsay patterson's, was more likely the true story of what happened. tom dove is a senior investigator for the riverside d.a. >> i think they felt there was enough to say this was not an accidental drowning, it was purely much more suspicious than that. >> reporter: and so before the night was over chris hall was arrested and charged with the murder of his wife. the girls could stop waiting. he wasn't coming home. >> it was obviously a tragedy losing our mother that day, but this is a tragedy on top of a tragedy now. >> because knowing that, our parents -- >> just the farthest thing from the truth. >> reporter: and one that felt infected by some kind of

madness, said the girls. christie was the love of their father's life, after all, the center of everything for him. how, they wondered, could anyone so happy in his marriage and his life be accused of harming her? and she was happy, too, they said, as happy as she'd ever been. they knew it, they said, based on that mother-daughter talk they had not long before she died. >> she just kept reiterating how happy she was. and me and bri always -- >> but that being the last time we actually saw her -- >> reporter: kind of burned into your memory, huh? >> yeah. >> reporter: but right or wrong, the legal trigger had been pulled. chris hall spent almost two months in jail until his daughters received the payout from christie's life insurance policy and used the money to meet his million-dollar bail. and then he went back to what was to be his retirement retreat to prepare with the help of his daughters for a murder trial. >> that's very surprising, to have a client in a murder case

out on bail. but he was a special man and this was a special situation. >> reporter: these are attorneys who would eventually defend him, though at first they only heard about the case. steve harmon and paul gretch. >> reporter: you've said two things there, special man, special situation. >> i think both of us can say this is a man that we like and that we know and that we don't feel he could have done anything like this. >> reporter: so chris hall and his daughters prepared for a trial which they hoped would make clear to everybody the police, the neighbor, the world, that chris would not, could not, did not harm the love of his life. >> there was never in 30 years of marriage, never one moment of violence. there was no motive for this man to kill his wife. >> reporter: harmon and gretch had a look at eyewitness lindsay patterson's account and concluded it was not conclusive at all, it was tragically incomplete. >> she saw three snapshots.

what is missed by everyone is the wife getting into the jacuzzi, slipping, falling into the jacuzzi, hitting her head, going unconscious, and drowning. >> reporter: see this sharp corner sticking out into the spa? hitting her head on this would certainly have opened a gash and knocked christie out, said the attorney. >> she didn't see what was really happening during the times when she was not looking. >> reporter: that scream that made lindsay patterson look over the wall? lindsay, they pointed out, was in a bathroom that faced the street. she wasn't in the back yard when she says she heard it. it could have been anybody. and courtney, who was inside her own house near the spar, didn't hear a thing. >> we don't think she's lying. we just think she misconstrued what she saw. >> reporter: and anyway, lindsay concedes she didn't know what she was seeing in her glimpse that's morning. >> something was wrong. >> reporter: and yet you hadn't really seen anything. >> no. but i knew something was wrong. i don't know if in my brain i

was putting things together. but from between the scream, the position that he was holding sxherks ju her, and just not having enough time for her to go inside. >> so sounds like you've got three different snapshots of something going on in there. >> right. >> and had to kind of work out what this was. >> yeah. i wasn't thinking at this point oh, this man just murdered his wife. >> but now, based largely on that account, chris hall would go on trial for murder. and it was a trial for his daughters, too. >> he loved her. they were each other's best friends. and this is just -- this is not fair to him because he truly loved her more than -- more than anyone. >> reporter: and yet the prosecutor was going to try to prove that this family man and former cop murdered his wife. could it be done? >> coming up -- the case begins. evidence is revealed in court.

bert strunsky is a hard-charging man, ex-member in good standing of the san francisco d.a.'s office, now senior deputy d.a. in riverside. that takes skill, persuasive powers. strunsky would need them in the murder case against the former police chief and family man, chris hall. >> mr. hall on the surface looks like a loving family man. he looks like a good father. he's somebody that had the support of his family. >> reporter: so he did. but strunsky wasn't buying the loving father and family man bit. no. when he heard about chris hall's very obvious grief, the wailing that went on after the so-called accident, the phrase that crossed his mind was "it's an act." >> i think it was a wonderful performance by the defendant of

acting like a bereaved husband. but when you look at his actions, how little he did to help his wife -- >> reporter: who tried harder to save cristi? not chris, said the prosecutor, but his daughter. >> she called 911. she helped him get the body out of the spa. she is the only one that did chest compression. he had no interest in truly helping his wife. >> reporter: a matter of opinion, of course. but prosecutor strunsky poked around in chris hall's past as a policeman. and what did he find? >> this man had an uncanny ability to fabricate stories. >> reporter: seven years earlier, while hall was chief of police in cascade, idaho, he was charged with and convicted of misuse of public money. embezzled $19,000, spent ten months in jail. a white-collar crime, hardly murder. but what struck the prosecutor is that he says hall tried to cover it up. >> to plan a fraud, to lie about it, not just lie about it but

lie about it effectively. >> i think that was very telling about who we were dealing with. >> reporter: suddenly the prosecutors' prospects were looking better. at the trial strunsky made lindsay patterson his star witness, of course. it was her story, after all, that got the whole thing started. but almost as important he called the riverside county medical examiner, who testified that those lacerations on cristi's head could not in his opinion have been the result of a single accidental fall. and the m.e. argued the particular type of bruising on cristi's face and body was a hallmark of homicide. >> the brutality of injuries were not consistent with somebody slipping and falling and then a rescue attempt. >> reporter: and there was a clump of hair in the bottom of the spa, still entwined with a broken plastic hair clip. that, said the prosecutor, could only have come from a violent struggle. >> when you lose that a hair, it's not reasonably explained by any kind of fall. >> reporter: there were some minor hiccups in the case. lindsay patterson, for example,

was a little inconsistent about how long she looked over the back yard wall that first time she saw something going on. was it just a few seconds or as long as a minute? but either way, said the prosecutor, lindsay was sure she saw physical contact. that was the important thing. >> he was given the opportunity to explain any physical contact that could in any way reasonably explain what lindsay patterson saw. in other words, were they washing each other? were they involved in a sex act? was there anything she could have misinterpreted? and at the end of the day you're not just stuck with the fact lindsay patterson made a mistake. you have to actually believe that lindsay patterson really hallucinated about everything she saw. >> reporter: and what made lindsay's story all the more convincetion, said prosecutor strunsky, was she told it before finding out what happened to cristi. she dialed 911 a full minute and a half before anyone from the hall house did.

before lindsay had any idea how it would end. here's what the jury heard her say in that call. >> i saw him put her under water and hold her there. >> reporter: and she was still on the phone with 911 when chris hall came outside and found his wife's body floating in the spa, called out for courtney. investigator tom dove. >> i heard it best described during the trial as a cosmic coincidence that someone could see something that they perceived to be more than just some kind of kinky action in the jacuzzi in the morning and then that actually turn out to be true, that a woman was actually drowned in that spa. that is not a coincidence. that is what she saw. >> reporter: the prosecution's theory? somehow sitting in the spa that morning chris was overcome by some private fury. who knows what? the hidden violence is what

strunsky called it. and then killed his spouse when he thought nobody was looking. >> chris hall ambushed his wife, grabbed her by the hair, slammed her head twice into the concrete edge. he's holding his wife of almost three decades under the water, she's absolutely no mercy and no remorse, and an absolute desire to end her life at that point. >> reporter: and then the piece de resistance. >> he then gets out of the spa, walks into the house where his plan is to wake his 22-year-old daughter, who he can use as an alibi witness. >> reporter: one little quibble. why? in fact, as convinced as he was of hall's guilt, strunsky conceded the why was a problem. he didn't legally have to know, he said, but he just didn't. there it was. >> it's emotionally unsatisfying not to have that answer, not to know the entire narrative of

what happened. >> reporter: but you'd want to know why this guy married to this woman for almost 30 years, apparently happily, would suddenly turn on her and drown her in the pool. >> right. i'm not sure we got the answers to that specific question -- >> reporter: kind of an important question, isn't it? >> it's an important question and a question we ask in all spousal homicides. >> reporter: so proof enough? or reasonable doubt? almost three years after cristi hall's death, a riverside jury would have to decide. >> coming up -- >> you expected a not guilty verdict? >> oh, yeah. >> not a doubt. >> but there was a surprise in store for both sides, in and out of the courtroom. >> she was having a little affair. right? >> when "dateline" continues.

it. you're basically telling us that we didn't know our whole lives -- >> there's no proof of that. >> reporter: chris hall had never been violent, argued the defense, had no motive, no reason to suddenly turn on his wife. it had to be a freak accident. so, said the defense, lindsay patterson didn't really know what she saw. in fact, if she'd really witnessed chris hall drowning his wife, why then didn't she claim to see cristi's body in the spa when she looked again? it didn't make sense. but the highlight was the daughters' testimony. emotional, quite powerful. so it put prosecutor strunsky in a strange position, at odds with the victim's own family. >> reporter: they were so clear, if we had any inkling he would have done, this believe me, we would have said so. we would have seen it. >> i think that's what they truly believe in their hearts. and it weighs on me greatly.

but my job is to get justice for cristi hall. >> reporter: now it was up to a jury to decide. after six days of testimony, two days of deliberation, they couldn't. it was a deadlock. the judge declared a mistrial. chris hall walked out of court with his family, free. but not quite in the clear. and nothing at all like the victory for the hall daughters. >> what was it like to get a hung jury? what did you think then? >> that was devastating to us. >> you expected a not guilty verdict? >> oh, yeah, without a doubt. >> reporter: deputy d.a. burke strunsky was disappointed too and was also determined to retry the case. at first he sent his investigator on a mission, to explore the life and marriage of chris hall. and what do you know? in idaho, where hall had been a disgraced police chief, the investigator uncovered a startling accusation. >> chris was a great, great con

man. >> reporter: former los angeles police officer jerry winkle is a county commissioner up in idaho now. but once upon a time he was chris hall's friend. that was before a night of poker and booze, when he said hall made a disturbing revelation that he'd shot himself in the leg when he was a cop in order to get medical retirement benefits. >> chris had been drinking beer, and he came right out and told me that he had shot himself. >> reporter: but there was more. d.a. investigator tom dove had discovered a secret. not in chris's past but in cristi's. >> there had been infidelity in the marriage for six years prior, while chris hall was in custody in idaho. >> reporter: cristi's affair was relatively brief, years earlier, but she'd been in phone contact with the man just days before she died. had chris found out? impossible to know.

but when investigator dove talked to cristi's co-workers at the clinic where she was an x-ray technician, several of them said they noticed a sudden change in her usually vibrant personality. one co-worker offered more. >> she told us that she was contemplating a divorce. >> reporter: if true, and it was only an if, it might well persuade a jury. but also, prosecutor strunsky needed to explain what lindsay patterson saw or didn't see. why didn't she see cristi's drowned body when she peeked over the wall a second time? >> we were not able to explain to the jury why she didn't see cristi at that point. and i think that allowed the defense to make the argument that cristi hall was inside. >> reporter: the prosecution hired a water expert to do a recreation of the hall spa. andrea zaferas has been assisting law enforcement nationwide with drowning investigations for the past 20 years.

zaferas got in the spa while strunsky videotaped from the spot where lindsay was watching. >> from the center of the pool and towards where lindsay was standing anywhere i was laying you could not be seeing from lindsay's viewpoint. so once i sank below the surface and hit that bottom, you could not see me at all from lindsay's viewpoint. >> reporter: and now the prosecutor was ready. in may 2011, one year after the first jury deadlocked, burke strunsky went back to court armed with his new evidence for a brand new panel of hall's peers. jurors heard medical experts testify about the injuries to cristi's head and once again heard lindsay's 911 call. >> i saw him put her underwater. >> reporter: cristi's co-workers testified for the prosecution. and jerry winkle traveled from idaho to tell jurors what he thought of chris hall. >> i was ashamed to admit that he was once a police officer. >> reporter: but it's the prosecution that upped its game in the year between the two trials, so had the defense. that's when well-known atern

steve harmon and paul gretch entered the scene. and they came out swinging. that story about cristi as fair, for example. >> there's a shadow hanging over all of this stuff. a very human sort of shadow. which is that she was having a little affair. right? had a boyfriend. >> yes. if the husband knew about it. but the wife never, ever mentions it and tells the husband. no one tells the husband. >> reporter: quite right, said the judge. and because there was no evidence that chris knew about his wife's affair, he ruled it out of the trial. and the story about hall shooting himself for retirement benefits? >> that was just absolutely a lie. that's wrong. there was never, never any evidence or indication or not even a moment's breath that he shot himself. >> reporter: anyway, the story was prejudicial, said the judge. so he threw that out too.

as for what lindsay patterson says she saw, chris patterson holding his wife's head underwater, the defense had prepared its own visual demonstration, had taken pictures from her angle at the wall to show that it could look like two people were touching in the spa, even if they weren't. >> this is what she described seeing in her testimony. but on the close-up what do you notice? >> they're not touching but they're in position where they could be. >> but that's different than actually touching. >> reporter: again the hall daughters were there every minute. their father's enduring champions. and this time more family members came to court, two of cristi's own siblings testified for chris. >> they said the same thing, we have not a doubt in our minds that this was not a moment of violence, this was not a murder. the victim's own sister and own brother. that's an amazing thing to see. >> reporter: perhaps it was. but listen to this. the defense had one more very

significant witness, a witness who n credibilitoo oozeed credi. the city medical examiner who stuck his neck way out to disagree in a court of law with the medical examiner from riverside. >> he found this to be an accidental death, not a homicide. >> reporter: this was not some ordinary hired gun. this was a public official who said straight out that cristi's head injuries could and perhaps should be explained by an accidental fall. >> he didn't rule out homicide, did he? >> he didn't rule out homicide, but he said the preponderance of the evidence was toward an accidental drowning. what i've always been astounded by with this case is that the hall family lived so close to the san bernardino border. if cristi had slipped and fell four or five blocks over, the

pathologist in that county would never have filed criminal charges. an accident of geography. >> reporter: so now a second jury would have to sort through these two sets of allegations, these two opposing realities, and decide whether chris hall would turn and embrace home and his loving daughters or a pair of handcuffs and a life in prison. >> coming up -- >> things can only go so wrong for so long before something has to actually go right. >> guilty or not guilty? this time the answer from the jurors would be unanimous. this ti[ female announcer ]he at verizonfios.com, you can choose your channel package. ♪ you can choose your own internet speeds. ♪ you can even choose to chat with a live person. ♪ now you can choose to save $35 a month for fios tv, internet and phone for just $79.99 a month, plus get a $300 verizon visa prepaid card with a 2 year agreement. but hurry, offer ends soon

may 2011. for the second time 12 men and women of riverside county, california filed out of the courtroom. a second jury to make a life decision about chris hall.

did he murder his wife? which of the medical examiners should they believe? whose account of the defendant's character? and perhaps most important, what did lindsay patterson see when she peeked three times into the halls' back yard? >> do you ever have those sort of little dark moments of the soul where you think, i may have misinterpreted, misremembered -- >> that is something i've thought about every day. whether i misinterpreted, whether i think i saw something that wasn't there. i didn't see everything. >> reporter: yeah. >> but i saw what i saw. and i know the conclusion of my story. i know it. i know it. right here. i know it. >> reporter: of course chris hall's daughters say they know the truth, too. real thing. in their hearts. >> i think that we were the three most critical jurors in that courtroom. believe me, if we had heard

anything or had any inkling that our father could have done this, as much as it would hurt and as much as we love our father, we would want that justice for our mother. >> reporter: the jurors deliberated two days, then broke for the long weekend. it was memorial day. hall's daughters felt good. >> things can only go so wrong for so long before something has to actually go right for us. >> we just did a lot of talking about the future. and this, you know, being over, this thing. finished. and honestly, i was concerned about dad and how he was finally going to be able to grieve for the loss of his wife. >> reporter: then it was tuesday, 8:45 in the morning. the jury gathered. and minutes later a signal. they were ready. chris hall and his daughters rushed to court. and in the end it was very

quick. guilty of first-degree murder. their father would not be coming home. probably ever. >> he's being cuffed and potentially put away for life. and yeah, it hurts. and we are angry about that. >> you can still hear those daughters thinking you're unfairly convicting their father. >> absolutely. it weighs on me. but at the same time i know who i'm dealing with when it comes to chris hall. in fact, he's the one that's stolen their mother from them. >> reporter: it had been a peculiar fact of this case that the victim's and defendant's fleemds h families had stood solidly together against the prosecution. but what no one knew was the truth was more complicated. after the verdict at chris hall's sentencing a letter was introduced. it was from another of cristi hall's brothers, billy carlton, who until now had said not one

public word about the case. "we would like to ask his honor for the maximum sentence," wrote billy. "the pain that my family has suffered through this tragedy is unforgivable." >> i didn't want to hurt the girls. i had to say what was on my mind. >> reporter: there was a deep divide in cristi's family, said billy. some of her relatives believed chris was innocent. but he and, he says, others, including cristi's uncle steve mundy silently urged on the prosecutor. >> half the family was convinced he was innocent, and half the family was convinced he wasn't. and that's hard to do when you have a big family and you all have to be together every once in a while. >> reporter: and when it involves a member as loved as cristi was -- >> exactly. >> reporter: does that explain why this kind of group of people in the family decided just to let justice take its course? >> we had talked about it quite a bit. >> i think so. >> and you've got to know when to show up sometimes and know when not to show up, just to keep what's left of the family.

as together as you can have it. >> thank you so much for coming. >> reporter: when it was over, paul convicted and sentenced to 25 years to life, some of cristi's relatives met with prosecutor strunsky, and thanked him. >> i wanted to thank you. for putting that man away. because he's a murderer. >> reporter: and the hall daughters, having lost their beloved mother, fought to save a father they adored. and having lost that fight aren't quite sure what they'll do now. >> it's hard-hitting reality. it really is. especially for our family -- to say we were close is an understatement. you know, to go from that to being not able to be there with each other. it's the biggest heartbreak that anyone could ever experience, i think.
