dennis murphy (voiceover): it was sunday, the morning after lisa techel had been shot to death. but it wasnt a day of rest for the techels and caldwells. it was sunday, the morning

after lisa techel had been shot to death. it was not a day of rest. they had to discuss arrangements. one of the saddest word in the language is arrangements. it must've been unreal. grief stricken, todd decided to stay home by himself with the rest of his family met in a park. seth was there but under instructions not to speak about the case. he shared an emotional moment with lisa's sister and her mother, tracy. >> seth grab the girls and said they think i did it. we all hugged seth and told him we loved him. >> when investigators finished difference i can set the trailer, tracy, seth, and his parents went out to retrieve some of lisa's things. >> it was very tough. >> the crime scene techs had been all over a. >> all over it. i guess i wanted to dad mode.

>> what was your thinking? >> i didn't want him to see the blood. >> how was your boy dealing with that? >> i think he was shocked. >> that sunday wasn't the day of rest for the men and women trying to solve the crime either. investigators were focusing on the murder weapon and were working a lead bennett 12gauge shotgun. it belonged to his seth's friend who had been rooming with seth and lisa and had just moved out. we should lucas's photograph taken of seth at his home. if you look in the upper right- hand corner, the gun rack, is your mossberg in that? >> yes. in the middle. >> lucas talk to deputies about the gun the day of the murder. >> but his 12gauge wasn't there when the crime scene techs scoured the trailer and cops know another place it was not. on the list of guns kept at the house that seth had written out

for the dci agent. investigators felt certain it was used to kill lisa but the big question remained. where is it? >> is what we want to know. where is the gun? >> that same sunday morning they began searching the beautiful piece of property with seth and lisa were starting married life and preparing to raise a family. the deputy working as first- ever homicide case was back at the scene. not too long into the sunday morning search over here by this tree, what do you hear? >> i hear. we've got a. shotgun here. >> there it was in the tall grass about 20 yards from the back door the trailer. that was a huge development. >> it was. everyone's mood doubled or tripled. >> ballistics would later match it with the slope that killed the pregnant lisa. investigators could fill in one big box on their checklist. murder weapon. next, they worked on possible

motives. was at a neighbor with a vendetta? or a has been lusting after another woman. the state agent birmingham and thomas decided to have a talk. >> we interviewed her may 29. >> someone lost their life. >> over the course of two hours, birmingham and phillips peeled back the layers of rachel's relationship with seth. >> they were having an ongoing relationship they were sexually explicit text messages and pictures. sexually explicit pictures. >> he kissed me. but it never let anything else. he used to tell me, love you. >> it sounds like they were making out rather than having sex. >> that is correct >> he always used to tell me how pretty i was and how he'd like to be with me. but i always made it clear that he is married and has a wife and he's having a baby.

i don't wreck families. >> rachel told the investigators the seth she knew could not be a murderer. >> what a surprise you? but seth was a suspect and if he did fire that shotgun blast, that would place rachel at the heart of a murder love triangle. >> i think that's why feel so guilty. i don't want it to be because of me. >> the next day, deputies phillips and wonderland were back at brian tate's house. this time they asked him point- blank about the murder of his neighbor. tate stuck to his alibi, home at asleep after taking his medication. the lead agent birmingham thought he was telling the truth and crossed brian tate of the suspect this. you only have one suspect at

this point. >> one suspect and only one suspect. >> that evening, lisa's loved ones gathered at a funeral home for the visitation. the turnout was impressive and included many of todd's friends in the sheriff department. your fellow officers are there, as they would be. they want to show respect. the mood inside was somber and an easy. the coldwell's gathered near lisa's coffin. the techels stayed in the back of the room. seth was there and his sister- in-law presley will never forget what happened thanks. >> he actually came up to me in the middle of it and gave me a big old hug. he said, you will always be my little sister and i love you. i was like, i love you back. >> when the last visitor was gone, only the two families remained. still, at opposite ends of the room. >> i saw the dci agent sit down behind me. a couple rows behind seth and i. i said is this a personal visit and he said professional.

>> marty wonderland was there. >> we asked seth to come outside and we did it quietly, i thought. >> when they were outside, the deputy carried out his orders. he arrested his friend, seth techel. a fellow deputy put the cuffs on. the ones she had used as a reserved deputy. this has to be more than your brain could absorb. >> definitely. >> little sister. i'll always love you. now he's going downtown. he's about to be charged. >> i couldn't understand that. we wouldn't ever understand that it could be him. >> seth stream is to drive a sheriff scars a deputy but now the wannabe cop was cuffed, riding in the backseat and about to be charged with the murder of his wife. >> coming up. seth techel goes on trial, but before it starts, the

prosecution suffers a major blow. >> bad for us. good for them. it is great for them. >> and then a clue could change everything. >> i believe it to be the most compelling piece of evidence in the whole case. even a little blurry vision can distort things. and something serious may be behind those itchy eyes. up to 50% of people with graves' could develop a different condition called thyroid eye disease, which should be treated by a different doctor. see an expert. find a t-e-d eye specialist at isitted.com nexium 24hr prevents heartburn acid before it begins.

that the authorities would come after him. >> he feels they're saying he was a murderer. brian had even seen they were calling him a crazy and deranged neighbor. it devastated him. >> that summer, brian tate tumbled into a downward spiral and never recovered. he died in september 2012 four months after lisa's murder. the coroner would think it was heart. >> we think it was heart. a broken heart. >> prosecutors from the state's attorney general's office worried that a jury might think the deranged, deceased neighbor did it. their plan had been to call take as a witness. >> on the theory the devil you know was always better than the devil you don't, we wanted the jury to see mr. t. >> now with the trial date approaching, prosecutors had lost a key witness. >> bad for us and good for them. it's great for them. >> the long-awaited murder

trial seth techel was in baltimore. february 2013, did you see yourself going in the courthouse? >> i remember. >> would you say? >> we've got to stay strong. >> caldwells never wanted to believe seth killed lisa but heading into trial, they were convinced he did. even presley, once his staunchest supporter. >> there's really no other explanation for what happened. >> when you left the techel resident, who was there? >> two prominent families, once close in-laws were fiercely divided. camped on opposite sides of the courtroom. seth pleaded not guilty. >> i was like, look at me. i want to see how you're doing. but, he doesn't look at you. >> she was my best friend. >> prosecutors called to the stand there and emotional trump card. todd caldwell remembered his lisa. >> how much lisa and i are

alike and i would tell everybody that she is the best parts of me. >> the prosecution had the burden of proving the charges. first-degree murder and nonconsensual termination of a pregnancy. what did you think your strongest fact was? the strongest part of your story? >> probably the single piece of evidence was the shotgun. >> ballistic show this mossberg was a murder weapon. the firearm that seth kept inside of his house. only he had access to it that morning, prosecutors argued. >> no murderer who wants to kill lisa techel comes to the murder scene without the murder weapon. >> we argued the impossibility of his story. unknown assailant breaks in the house and kills the wife he said he's going to leave. >> prosecutors called one of seth's young prince to show the jury just how deceptive and manipulative seth was.

this witness was one of the boys it turned out behind all the vandalism across the fence. he testified he was just following seth's orders. >> he told us to go mess with his neighbor t. >> how are you going to mess with him. >> fill buckets full of dog manure and dump on his property. >> remember seth assured his father-in-law and the state agent who interviewed him the opposite. >> i'm not messing with him. >> looking back, that incident is what turned todd against brian tate in the first place. fixing the idea in his mind that his kids neighbor was a to range, maybe dangerous prank. >> i'm going by what seth told me about him. >> as for tate's complaint calls to deputies has captured a dash cam video, it became evidence for the prosecution. >> we were hopeful the jury

would see brian tate as we saw him. >> and they saw him as an eccentric but harmless man. certainly not a killer. >> at last, it was time for the star witness, rachel mcfarland, the other woman, to show up and tell her story. digital need the jury to like her? >> we needed the jury to believe her. >> she testified her relationship with seth started heating up in december 2011 which was two months after seth got married. >> it became more sexually asking me to send pictures or showing off my body. >> may 20, 2012, seth and rachel met at a nature preserve. where they took this selfie to remember their time together. >> he kissed me, touch me. he said we had everything in common and he tried working things out with lisa and they

weren't working and i was exactly what he wanted. >> he said seth repeatedly told her he was going to divorce his wife. >> did he say he loved you? >> yes. >> rachel was hedging her bets. she told seth she was interested in a coworker brandon who happened to call her during her tryst with seth and the car. >> they started getting really jealous. >> when he learned you were communicating he said what? >> he said give me two more weeks? >> did you ask him what he meant? >> he just repeated the statement. >> six days later lisa was murdered in her bed. >> year we have a motive we can understand. love, the relationship with rachel was evidence, it was a countdown to lisa techel 's death. >> but the defense attorney countered arguing the motive falls flat without the essential element. sex. >> seth techel was being accused of murdering his wife for an affair that he was hoping

to someday have. >> you never had intercourse with him? >> no. >> you never had oral sex with him? >> no. >> you never had your clothes off? >> no. >> you kissed him. >> is that a fair assessment of the extent of your relationship with techel? >> yes. >> they didn't accept the take on the neighbor is a harmless eccentric. >> the most compelling evidence as to how this involved the neighbor. mr. t, he was mentally ill. >> according to the defense, dangerous too. the defense hammered home the portrayal of the unpredictable neighbor by using todd's own complete summary from that day. here in the awkward situation of being the best witness. >> right. >> you believe he could become a danger. anyone who should respond to that residence again should use

extreme caution. >> that is correct. i did. >> the defense theorize that t entered the trailer through an unlocked door and shot lisa for revenge. the key defense evidence that suggested an intruder was a peanut butter and jelly sandwich in a baggie left on the back deck. >> there was a sandwich that would not of been there the night before that was there. >> critters should've devoured it he argued. he told the jury it must've been the killer's snack. >> i believe it to be the most compelling piece of evidence in the whole case. >> it was now up to a jury to decide, but it would not be easy. >> coming up. in the jury room, deliberations and drama. >> he started pounding on the door saying he wanted out. we were in tears. ing you they may have allergic itch? apoquel is the #1 treatment for allergic itch... that veterinarians have trusted for over 15 million dogs... and it starts working

room, wrangling jurors in the seth techel murder trial enjoyed at your table. were driving the case into a ditch. : they stay out and they stay out and they say out. back in the back in the deliberation room, jurors in the seth techel murder trial were driving the case into a ditch. >> they stay out and stay out and stay out. >> there are some that are guilty and some not guilty and they are not agreeing. i'm starting to get worried at that point. >> like i was on the jury and said one holdout juror in particular was responsible for the stalemate. >> he started pounding on the door saying he wanted out. we were in tears. a lot of us because we knew

that we were up against a wall. that nothing else could be done with this person. >> after weeks of testimony and three days of deliberation, the trial came to a sudden conclusion today. >> it was all over. >> the motion for mistrial is granted. >> the judge declared a mistrial because of a hung jury. >> i have never had one in almost 30 years. >> prosecutors decided to retry the case. the vote was 10-2 for conviction. >> we are disappointed in what happened. >> reporter: the called walls lusty daughter and sister and now they couldn't get the closure they desperately wanted. they would have to do it all over again. >> it's hard to know you after enter another one. >> a trial date was set for seven months later. october 2013, and trial number 2 would be heard in a new courthouse.

there had been a change of venue to the town of mount pleasant. making it tougher on the called walls. the daily track to court, lives disrupted. the new courtroom had a distinctive layout the put the caldwell family directly behind the defendant. >> he's literally sitting in front of me like you are. >> which only made a four difficult for presley who is trying for any connection to someone she once loved like a brother. >> i am staring at him. glance at me. do something, and he doesn't. >> even more painful for the family is having to sit through again all the heartbreaking testimony and raw crime scene photos of their lisa and the unborn baby girl. other than the change of venue, seth techel's trial played out as a carbon copy of the first. same lawyers. same judge. same arguments. a replay of two opposing theories. brian tate, the other suspect versus seth techel, the husband

with the other woman. rachel mcfarland was again the star witness. >> may 4, 2012, he sent a message with a picture of his own smiling face heating miss you, bella? is that a term of endearment he called you? >> yes. >> he sent a picture of you in a bikini her bra and underwear? is that right? >> yes. >> he said, wish me luck. i love you. 10:51 p.m. on may 24, 2012? what was he asking you to wish him well with? >> i believe he was going to tell her he wanted a divorce. >> two days later, lisa was dead. by now, her family hardened opinions about rachel. >> i don't think too highly of her. i feel she destroyed my sister's marriage and life. >> i and maybe not the most

popular view. i blame her for the part she played with seth. i think she's a victim as well. >> the defense of for the jury the same bogeyman as before. >> the defense went even harder at brian tate then they had the first time around. >> he could become agitated. >> this time the defense over strenuous prosecution objections got t psychiatrist to testify. heat treated him at a mental health unit. >> did you find him to be paranoid, delusional? >> yes, sir. >> was there a topic of dilution which he was paranoid? >> he seemed to make reference that there were governmental conspiracies affecting him. >> after three weeks of trial, second jury had seth techel's fate in their hands and that's

when things got dij@ vu all over again. the judge read a note from the foreman. >> if we can't reach a verdict, what's next? >> it's happening again. >> this is two months worth of trials and were back to the beginning. >> the judge wasn't ready to give up. he told the jurors to keep trying. emotion to the open courtroom were raw, especially on the caldwell side. the jury couldn't help but here it. >> presley and i were crying. not uncontrollably but you could hear sniffling a little. >> as the jury filed out the defense attorney, schooled the spectators. stop the outburst he said, or he would demand a mistrial in fairness to his client. >> i do not desire the jury to be influenced by the public. >> now, it was a prosecutors turn. >> the defense is making a speech about the caldwell family trying to influence the jury which we thought was ludicrous.

i squeezed andy's arm and said i will take this. >> to stand up here and suggest anyone in the courtroom is making an attempt to intentionally influence the jury's absolute nonsense. >> the courtroom started to settle down and clear. seth remained at the defense table and his former father-in- law ready to pounce. >> i was breaking, please let me stand here. >> for more than a minute, burning a hole in seth's back. if looks could kill. >> there was an urge to move forward and, god, just let me stand. >> what were you doing in your mind? >> i don't want to think of what i was doing in my mind. i wanted to do something. >> two hours the jurors return but nothing changed. >> a mistrial is declared. >> unbelievable. veteran prosecutors were now 0- 2. the state did not hesitate.

seth techel would go on trial for a third time. >> our intent is to retry it. it was an easy decision to make. >> even though the vote was in favor of conviction, 9-3, lisa's family was starting to have it stouts. >> is there something i'm overlooking? did he not do it? is there something they see? he's not guilty? >> just when they thought they couldn't suffer any more heartbreak, the called walls would be devastated by new findings by a new defense team. >> i heard it about a week before the trial. it was like somebody hit me in the stomach. >> coming up. the defense comes out swinging. >> we chose to focus on a sloppy work done by law enforcement. there was no dna, fingerprint, confession. respiratory disease from rsv in people 60 years and older. arexvy does not protect

convict seth techel. they didn't like those numbers and decided to head in a different direction. >> we chose to focus on the sloppy work done by the law enforcement. there was absolutely no dna, fingerprint, confession. >> he would argue was a botched investigation. why would crime scene tax to test to match the slug to the murder weapon but never check it for fingerprints or dna that might link it to the shooter. >> did you test the bullet in the chamber that killed this woman? no. we forgot. we didn't do it. >> the new defense team had in to story to tell. it was a rush to judgment to blame seth who had been in jail ever since his arrest two years earlier. there was another big strategic shift. they was soft in the focus on the bogeyman of the first two

trials, brian tate. >> our conclusion was after listening to the tape of mr. t he was not the deranged person they were trying to betray. >> the way he was speaking to law enforcement that afternoon when it seem like the person who would walk into a trailer home at 5:00 a.m. and murder his neighbor. >> the defense attorneys made a tactical decision. since recordings of tate didn't make him look like a dangerous killer, they would not show tapes of him to the jury and they rolled the dice hoping the prosecutors wouldn't either. the called walls and techels had been put through the ringer for more than two years. there once close relationship had frayed in the third try was pushing everyone to the brink. it was an impossible situation but somehow todd caldwell and techel found a moment of grace. >> i went over to him and i said, i want you to know that i think you are a good person. no matter how this turns out, i want you to know that. he said i think the same with

you todd. i went to shake his hand and he hugged me and we both hugged. >> the two fathers returned to opposite sides of a murder trial. july 2014 for the third time, the state of iowa versus seth techel. this time in davenport, three hours from the first courthouse. the prosecutors once again argued that the story defied logic. >> he would have to be the victim of one of the largest coincidences ever known and he told his girlfriend he loved his wife and less than 17 hours later some assailant breaks in the house and kills the wife he says he's going to leave. >> with a weapon which he hasn't brought with them. >> i had a mossberg shotgun. >> seth prosecutor said had easy access to the murder weapon. the shock on his friend lucas kept in his house.

>> the shotgun you left behind? >> the prosecutors argued only seth had a motive. they said seth and rachel's steamy text, cell phone photos, played like a countdown to murder by seth. >> u.s. time, do you really want to be with me? he response, forever? >> right. >> that's may 24, two days before lisa's death and did a follow-up text, rachel asked seth if he told his wife's he wanted a divorce yet? >> he response, well, we talked. i told her i wasn't happy. she got mad. then said. then i slept on the couch. >> correct. >> rachel told the jury that she and coworkers nicknamed seth mr. resuscitate her because it was a volunteer

state has proven that seth techel did it. >> new defense attorneys had a completely different strategy. they barely mentioned tate's name. rachel offered a motive in earlier trials was also minimized this time. in cross examination, rachel was on the stand for seven minutes. there was the message on thursday. mr. and misses resuscitate her. blue skies ahead. we are a couple. what do you do with that? >> i tried to be as straightforward as i could with the jury. who would murder their wife to facilitate a relationship that hasn't even turned sexual. >> you are not having sex with this man? >> right. >> the only time you've seen them in person outside of work is four or five times? >> correct. >> you want the jury to think,

you're going to shoot your wife for this? >> the attorneys then went on the attack. characterizing the work of investigators has willfully shoddy. >> and's consistent, incompetent, incomplete. >> this was what investigators did not do. the state criminalist had to admit they did not test for gunshot residue on seth techel. >> how many times you think you test about a criminal trust that gunshot residue was evidence of a crime? >> a lot. >> in this case, we can't argue because we don't have it. >> yeah. exactly. we will never know. >> the defense said it was even more shocking that the state expert had to make a similar admission about the fatal shotgun shell. >> this is the shell that killed lisa techel. >> yes. >> the very shell that killed this woman was never examined by the state.

they said we forgot to do it. >> the centerpiece of the case against the cops was something else they did not do. they had been so busy investigating seth, who had been be back behind bars that they never really paid attention to lisa. the new defense team would change that starting with her cell phone and the secrets it held. you found out the story that there is a guy, coworker? >> right. >> it was a bombshell. lisa was having an affair with a fellow jailer. her lover was a married man, father four. this isn't making out in the back of a car. >> no. he thought he was the father of her car. -- child. >> inmate 2012, did you know lisa techel? >> yes, i did. >> he testified the affair started before lisa married seth and ended weeks before the
