" >> shirley, the farm wife and mother, had been gunned down in her own kitchen and there was no obvious explanation for the crime. as investigators began digging into the carter family background, though, they came across a detail that became the focus of investigation. it concerned the son jason. the one who'd found his mother's body. >> we found out jason carter was having an affair. >> how had you find that out? >> a friend during the interviews. >> so who's this girlfriend? >> we locate her, we bring her in and we determine there's another phone in play. >> another phone? >> a phone that they just had. >> the lovers had, what they call burner phones, off the book. >> burner phones, we call it the sexting phone.

>> jason kept it stashed away hidden under the hood of his pickup truck. jason not only didn't mention the affair in his first interview, he also never told investigators about that secret phone. does it change him, where he stands in your suspects? >> absolutely. he gets elevated at that point. >> if jason had tried to hide the affair, agent ludwick wondered if jason was hiding anything else about his mother's murder. the investigator called jason and told him he knew about the affair and the phone. >> so, he says, i will meet you at the sheriff's office. he's there and he hands the cellphone over. >> says here you go, knock yourself out, huh? >> yep. >> then surprise. jason wanted to talk some more. >> he comes in on his own free will, no attorney. >> in this video investigators went over his story again, in detail, the time line of that morning. >> how long from 911 phone call till your dad got there? >> 9 minutes. >> jason was bent on letting

them know he had nothing to hide. no matter how long it took, bring on your questions. >> and he sits in a chair and he proceeds to sit in this chair for over 10 hours. >> let's do this. let's step out. we're going to give you a minute. >> i'm fine. >> doesn't shift. doesn't move. doesn't stand up. >> no bathroom breaks, no nothing? >> we begged him to take bathroom breaks. we begged him to bring him food. >> brought you that. don't know if you want it or not. >> you need anything else? >> what's that about? >> he's going to stay here until we believe him. >> he admitted to being unfaithful, but said it was ludicrous to think he killed his mother. >> i never hurt my mom. if you want to hold those affairs against me that's fine, but i never -- >> this isn't about the affair. >> i never hurt my mom. i walked in and found my mom the way she was. >> this is about shirley being killed. >> i know that and you're not doing anything about it, because whoever did kill her is still out there.

>> he headed home, but a cloud of suspicion hung over the carter family. not only over jason but bill, too. bill knew agent ludwick was looking at him since he was the last person known to have seen shirley alive. >> and he said, you know, you could have done this when you brought her back from coffee. >> then for weeks, nothing happened. >> we have no leads. nothing's going on in the investigation. >> so, the shirley carter murder case was heading to the cold case file? >> it was headed that way, yes. >> but bill carter wasn't going to let that happen. he hired his own detective. nick webb is a crime scene analyst and a former homicide detective from texas. bill instructed him to dig into the case with an open mind. if it's the good, the bad and the ugly, it's all going to be in your final report? >> we are only advocates for

the truth. >> to aide in his investigation he purchased a rifle similar to the one missing from bill's basement. the remington rifle emits at least one of those shots would have flown out as the killer racked another round in the chamber to shoot shirley twice. >> it was never found. >> so someone had the presence of mind to gather it up. >> that's correct. >> and since webb had to look at every possibility, he examined bill's day the day of the killing. phone records showed shirley making a call at 8:45 am. by 9:00 a. m. bill was spotted at the granary 50 miles from the house. webb said bill's only opportunity to kill her was after that. >> bill has to leave the granary, has to get home, kill his wife, shirley, and then leave before jason can get there. >> is it impossible for bill to do all this to-ing and fro-ing in the time allowed. >> it would certainly be a tight time line. >> squeaky to get it done, huh? >> certainly. >> then the private analyst looked at jason's time line. >> he already puts himself there. so, jason simply has to commit the murder instead of doing the other tasks that he said he did. >> is it your belief jason shot his mother? >> yes. >> painful as it was bill had been suspicious of his son

early on, and remembers a moment it all became clear. not long after the murder, bill says, jason found out he was going to visit his lawyer. >> he came barging through the door and he said what are you going to go see your lawyer about? and i said, i just need to get some things straightened out. there's some things that don't add up, and that's when he slammed his fist on the counter top and he said, "my life is over." >> his life, jason's life. >> his life is over. i knew then he had done it. >> it was a shocking realization. >> you're telling me your boy became a monster. >> he did. he did. i'm ashamed. >> you shouldn't be ashamed. you did everything you could for the boy. >> i didn't do something right. shirley and i did something

wrong. >> bill carter tired of waiting for the prosecutor. he the father, would take the almost unprecedented step of bringing his son before a civil jury. >> my attorney said, you know, we can file a wrongful death suit, and that will force the county attorney to make a move. >> bill was about to sue his son for shirley's death. if the jury ruled for the father, jason wouldn't face prison, but something like financial ruin. >> coming up -- >> plaintiffs call jason carter. >> father against son. >> you became a practiced, skilled and chronic liar. >> son against father.

? >> he totally failed a polygraph. >> not evidence, but guidance. >> strong guidance, yes. >> in march 2019, the curtain came up on the criminal trial. it was first degree murder and jason carter pleaded not guilty. as much as he wanted his son to face justice, bill carter knew there would be no winners. >> i knew there wouldn't be a good outcome. >> why do you say that? >> if my son is guilty of first degree murder, that's not a good outcome. >> that's a bad choice? >> you'll hear prosecutors talk about motive, means and opportunity. well, means. the two 70 was in the home with ammunition. opportunity, 13 minute gap in his timing. so, let's talk about motive. >> district attorney, ed bull, was telling a jury in council bluffs, iowa, jason was stressed over his finances that day he killed his mother. >> this case isn't about money, it's about pressure. it's about am i going to be able to be a full-time farmer? >> this time around, the burden of proof would be higher. beyond a reasonable doubt. and that's a prosecutors challenge without that rock, solid csi style evidence that juries love. >> i want three things in a

homicide case. i want forensics. i want a confession. and i want an eyewitness. in this case, i had none of those things. >> would ed bull pretty much follow the map of the civil trial. while the jury was it allowed to know about the civil case or it's outcome, ed bull's hansen would also be tied by the judges ruling that the jury wouldn't be allowed to hear jason's affairs. or the steam is text on his secret phone. and that jason had lied about all of that at first. tara hope, the girlfriend took the stand, but only to testify to the gap in jason's timeline and to the abrupt end to their conversation. >> was your conversation that morning without telling us any of the details, such that you expected it was at a logical stopping point? >> no. >> as to motive, in his opening, the da had mentioned the financial pressure on

jason. but in the end, he found it hard to explain why jason would have shot and shirley cold blood. >> there's absolutely nothing i can tell you that would make sense of why it is a sun shoots and kills his mother. >> now, it was time for the defense. jason carter's attorney, christine, had a clear message for the jury. a shoddy investigation, focused on jason early, and never looked anywhere else. and there were plenty of people to question. >> very significant parts of this investigation simply weren't completed. weren't followed. we're down. >> so, war room, christine? what is the biggest thing you have going in your favor in this thing? >> there really was no significant evidence against

jason carter. >> as in the civil case, the defense attorney argued jason had a loving relationship with his mother. and that his allegedly incriminating, how did he know the statements were taking out of context? and by the way, he wasn't in any financial trouble. >> there was 3000 deposited that day. and another check for $3,000 in the mail. and $175,000 worth of green in the farm. >> and as to the erupt ending to jason's texting with his lover on the day of the murder, the defense attorney asked the girlfriend on the stand -- >> did you perceive in any way that jason carter was troubled on the morning of june june 19th? >> no. >> then there was the timeline of that morning to deal with. all along, based on statements of first responders and crime scene techs, it was estimated shirley had been murdered sometime just before 11 am. when jason admits he was at the farmhouse. to counter the time of death, one of the nation's most famous pathologist for hire, cyril wecht, took the stand. cyril has been involved in thousands of cases from the jfk

assassination to o. j. simpson. >> you are at asked attempt to determine approximate time of death for shirley carter? is that correct? >> yes. >> were you able to do that to medical certainty? >> yes. >> he told surely that may shirley have been killed two hours earlier than anyone thought possible. if you ask wreck, then shirley was murdered around 9 am, when jason was seen on video, clearly still at the greenery. he could not have killed his mother. >> so, when the state says to you, all clues point to one conclusion, it's all the clues that the tunnel vision of law enforcement and one investigator in particular went after. >> the defense attorney said the tunnel fish and investigator with special agent mark ludwick. now he reluctantly became her star witness. with christine rattling off the names of victims who had come during the investigation. >> you were not very aware of cali's involvement. >> that's right, yes. >> not aware of jeremy morris. >> i did become aware of jason morris. i'm not sure at what point.

>> and that would be jeremy morris. i think you said jason. >> yes, my mistake. >> and that was a big part of the point we were trying to make to the jury. >> while jason's lawyer argued the investigation hadn't been thorough, agent ludwick told us none of the names the defense race or viable suspects. and they had followed everything. even once deemed not criminal. >> no credible information. >> would the jury see reasonable doubt or would jason carter be spending the rest of his life in prison? the attorneys would have one more chance to make their case. >> coming up -- the verdict. >> i ask you to return the verdict of not guilty. >> there are only two people who knew what happened that day. one of them is dead and the other one is sitting in that chair. >> when "dateline" continues.

raised for father and son. here's dennis murphy with the conclusion of, the farm. >> the case of the state of iowa versus jason carter was about to go to the jury. >> there's so many holes in this investigation. there's so much that isn't even explored. >> jason's defense attorney made one last plea. >> and in reality, the forensic evidence says jason carter couldn't possibly be guilty. i ask you to return a verdict of not guilty. >> now, the county prosecutor argued, all the viable leads were followed and the defense was just so much smoke and mirrors. >> if you believe this is staged a burglary, then all of the names and stuff they put up on the board is irrelevant. >> ed bull tell the jury jason just snapped that morning and in a fit of rage, had killed his mother. >> there are only two people who know what happened that day. one of them is dead and the other one is sitting in that chair. find him guilty as charged. >> it took the jury less than

two hours to reach a verdict. about the same duration as the civil juries deliberation. and remember, that jury had found jason liable for his mother's death. so, that lead investigator felt good about things. >> we felt this is it. and i had that feeling and emotion of, he's going to be found guilty. >> ludwick assembled a team to take jason into custody after the verdict. >> ladies and gentlemen, do you have a verdict? >> yes, we have. >> jason knew a conviction could send him to prison for life. >> we the jury find jason carter, not guilty. >> is that for your verdict, ladies and gentlemen? >> yes, it is. >> not guilty. jason had gotten his life back. >> it can go home and see my kids. it's been a long time coming.

>> jason was a free man. that district attorney says he gave his best shot. >> so, you're giving the jury this argument of a moment of rage, but you can't really play that movie for them egg explain what it was. it's not a very satisfying thing to see, something happen, he went downstairs, got the rifle, killed his mom. >> i don't disagree with you. i wish that there was a better story i could tell, but i'm limited based on what the facts are that i can prove to a jury. and that's the best i had. >> but that wasn't good enough for bill carter. >> the worst thing i was afraid of was that shirley would never get justice. and that happened. >> is this case closed? >> yes. we believe that we held the right person accountable, but new if new information comes forward, we will continue to investigate this. >> that's just what jason carter said he wanted. find the killer. he declined an interview with "dateline" but, his attorney said he realizes some people

will still believe that he shot his mother to death. >> jason knows that until someone is conclusively proven to be a murderer, some people will still suspect him. >> the 10 million dollar civil judgment against jason remains in place. after the trial, jason returned to the life he'd always known. as a farmer with cycles that don't stop. it's planting season, i imagine seeds are going in the ground? >> that's exactly it. i know that he was planting on easter day. and jason saw his father out planting at the same time. >> what did he think? >> he said, his thought was, it just seems wrong. they should have been the time where we are both planting. and we went in for easter dinner together. and it's hard for him to understand how his family ended up split up like this. >> and on his side of that field, bill carter watched the son he love so much work the

land. just as he taught him. >> i have to farm right across the fence from him. >> and you see him? >> from here to that wall, from yesterday. >> a few feet but an unbreakable divide. but it's a matter of father versus son. >> that's all for this edition of "dateline." i'm natalie morales. thank you for watching. for wat i'm andrea canning. thank you for watching. >> this is dateline. >> he wasn't my biological child, but my heart, you can't tell that to my heart. i love that boy. it's not fair thought he was taken from his children or from his family. >> jessie fell for vince, a man in uniform holding the fort during his long deployments. >> my hat goes off to all military wives. it's not sy
