They were fearful. I was fearful. Go get him go get him now i thought, they better get to him before i do. Reporter but there were rumors of trouble on this side of the fence. A husbands lust did he tell you, she sent me some topless pictures . Yes. Did you see them . Yes. Reporter then a wifes double life exposed. That was her biggest secret. A case that would test three juries and shatter two families. Before uncovering one terrifying truth reporter this has gotta be just more than your brain can absorb. Definitely. Its heartbreaking. Just like somebody hit me in the stomach. Reporter the cornfields of are a far piece from memphis. But it was here, in ottumwa, iowa, a baby girl was named after a princess. Lisa marie. Yup, that one. As a kid, i was pretty big into elvis. I knew that my first daughter was gonna be lisa marie because of elvis, of course. Reporter just as Todd Caldwell hoped, his little lisa lived up to her big name. She was just the life of the party. Once she started talking, she hadnt shut up. Reporter theyre divorced now but tracy and Todd Caldwell watched their girl grow up all but unstoppable. A vivacious, winning teen. Bowling, todd, were not just night now and then . No, were talkin about a state champion bowler. Anything she did, she had to be the best at it. Lisa, look over here. Reporter lisa was a teenager todd remained an active father to lisa and his three other children. Deputy in the Wapello CountySheriffs Department. He found comfort in several ways. One was his occasional hobby. Hed take out his sketch pad from time to time. And then he met and fell hard for a nurse named amy. Before long, he was starting fatherhood all over again. With twin daughters this time, he was getting lots of help from lisa. She was the twins default babysitter. She was more like a second mom to the twins than a big sister. She was just a caregiver to anybody. Reporter you had a very close relationship . Uhhuh, very. I would get into bed with her. Wed watch old episodes of the golden girls. [ laughter ] reporter thats a sweet relationship. Yeah, and she always says that i was dorothy because im such a grouch all the time. [ laughter ] but yeah, that was my favorite time with lisa. Put on her enforcer hat when it came to lisas teenage romantic life. I wanted to know who the boyfriends were. I wanted to know who their parents were. [ laughter ] i was the one that they had to pass the test with. The boyfriend who passed with flying colors was seth. He came from a long time local family. His grandfather was the mayor. Mom was a social worker, the dad owned a local Bowling Alley. The Bowling Alley was where seth as a young teen began noticing lisa. His dad was her High School Coach and seth bowled almost but not quite as well as lisa. The two worked parttime together at the lanes. They were becoming boyfriend girlfriend and that was fine with both families. You liked this young girl . A lot. She was a part of our family. They were a church going family and seths mom remembers Relief Mission to mississippi after hurricane katrina. He just would talk to the folks for hours and hours. They became very good friends. I have a lot of memories like that of seth. Helping people. Yeah. And lisa wanted to help people, too. She followed her father into Law Enforcement and then as a jailer in a neighboring county. I told her that she would have my blessings if she wasnt just an average cop. I wanted her to be a really great cop because i didnt want to have to worry about her inefficiencies maybe endangering her life. After years of hearing patrons at the Bowling Alley when they would get married, official. How did you find out they were getting hitched . Met with us and asked us our permission to marry lisa. Old school. Old school. After dating for seven years, seth and lisa got married in october 2011. She was 22, he was 21. I just told him that, no matter what he did, to take care of her and protect her. And he said . He said he would. Lisas sister, another namesake, got much more than a brotherinlaw with seth. He was my best friend and he was that other person that i could always go to. He called me dad. We told each other we loved each other. We hugged every time we left each other. I felt as close to him as i did my son. For lisa, it wasnt just gaining a husband, it was having all his buddies come along, too. A package deal. How did she put up with you guys . She was interested in the same things that all of us were. She liked to go fishing. She liked to go hunting. She liked to shoot guns. Was she okay . Sounds like you would have girlfriend . Seth was lucky. Lucky for sure. But seth knew it was time to settle down and get a real job. Like lisa, he was drawn to service. He drew a paycheck as a security guard. His fatherinlaw todd was helping him get a higher rung in the ladder. The soon to start job as a jailer for the sheriffs. They were very close. Todd was a big influence on seth. Thats why i think he went into Law Enforcement. Now more changes for seth. He was going to be a father. They picked a name for the unborn girl, zoe maria. In may 2012, they were halfway through the pregnancy. Seth and lisa, a baby on the way were starting out their married life in this humble little trailer. It was a gift from his dad purchased on a beautiful piece of property. A starter home to save money for the future. The only apparent cloud in the picture was an escalating feud neighbor. There was bad blood. It happened at 5 00 in the morning. A sudden horrifying sound that shattered two young lives. 911. Saturday, may 26, 2012, memorial day weekend. Not breathing.

All was quiet and with the first hint of daybreak that saturday morning, marty relaxed and turned up the music in his cruiser. Reporter its the ragged end of the shift for you, huh . Yeah, im taking my last little loop around the county and going to watch the sun come up and go home and go to bed. An abrupt end around 5 30 a. M. , when seth techel made a desperate 911 call from his house. Shes been shot. Im going to [ bleep ] kill who i was getting ready for work and i heard a gunshot and i came running out and she was shot in the side. Reporter dispatch relayed the message to marty wonderlin. The young deputy had never gotten a call like this. I have a report of a lady not breathing. I have now been advised this ladys just been shot. Reporter is your heart pounding a little . Oh, yeah. Reporter with his car and his mind both doing 90, marty raced to the house in under ten minutes. He slowed along the rise of the gravel country road and stopped at the end of the driveway. He had no idea what hed be facing. His dashboard camera captured reporter heres how you get in the trailer. What do you see, right about here . You could see seth techel up on the porch. He was wearing cargo shorts and a belt, and he just bent over, you know . Reporter whats he doing . Sounds like hes crying, just sobbing. Reporter the toughest call of martys career was suddenly so much more complicated. He knew the grieving husband on the porch, considered him a friend, knew his wife lisa too. And her father, todd, was a respected, fellow deputy. The unfolding tragedy had just become very personal. Reporter deputy, how do you set your brain in compartments, where you got to be very professional . This is the first time youve had a major crime, and yet its also people you know . Its tough. Reporter were you scared . Its okay if you were. Yeah, definitely was scared. You know, concerned about a lot of different things. Reporter you didnt know if somebody could have winged a shot at you . Yeah, i mean, that was possible the whole time. Reporter as the only cop at a dangerous, chaotic scene, the possibility of a live shooter still on the grounds, martys when he entered the trailer, a paramedic was attending to lisa. She was lying in her bed. It didnt look good. Martys only thought was to help her, but he had to secure his rifle, so he ran back to his cruiser to lock it up. I got on my radio and i think i told dispatch, get 58 out here. Call 58 and have him get out here. Reporter badge 58 meant deputy Todd Caldwell, lisas father. In hindsight, i wish i wouldnt have done that. I wish i would reporter why do you say that . Well, because i saw a lot of things that morning and now because of me, because of asking him to, you know, come out there, hes going to have to live with some of those same images that i do now. Reporter Todd Caldwell was asleep, but his cell phone was plugged in next to the bed, always ready for a middleofthenight emergency call. We get a call from, you know, a dispatcher ive known for 20 years and i can tell that his voice is different. And from what i remember, he just said, you know, you need to get out to lisas house. Breathing. Reporter todds wife amy bolted out of bed. Her stepdaughter, her best friend, needed her. I kinda left him behind. I didnt put shoes on, didnt have socks on. I went in my pajamas and drove 90 miles per hour, you know . Im an e. R. Nurse. Im thinking reporter youre sort of in nurse mode there too . Yeah, im thinking, well, you know, maybe if i get there fast enough minutes matter. There will be something i could do. Todd raced behind in a separate vehicle. I just repeated over and over, you know, oh my god. Oh my god, oh, my god. I just remember thats all i could think and say is, oh, my god. Oh, my god, oh, my god. Reporter at the scene, deputy wonderlin ran back to the house and did what he could to help the emt. Started giving lisa cpr, so the paramedic could i think he was getting, like, a defibrillator ready. It felt like forever. You know, and im asking him, you know, you want me to do cpr still . He told me not to. Reporter there was nothing she was gone. Along with her unborn daughter. Lisa marie techel was just 23 years old. I ran in there and you could tell that she was gone. Reporter so you went into the bedroom . You saw her . Did you tend to her . Yeah, i held her hand and i rubbed her belly and i just said, my my lisa, my lisa. Reporter todd, did you go into the house . I hope not. Yeah, i did. I went in there and i seen her laying there and i seen the amount of blood that was on the bed and i knew, from my experience, that that was too much blood to sustain life. When i listen to like the tape recording of it, i hear myself bellowing. I dont know how to describe, but i dont even remember doing that. What happened . Marty wonderlin had a job to do. End of your shift, your first homicide. So youre in the barrel here. Got to start working it. Reporter there was an immediate lead from, of all people, Todd Caldwell. The veteran cop, who had just seen his precious daughter lying dead in a pool of blood, said he knew who the shooter was. And in a voice filled with rage, he told his fellow deputies to take the suspect down. That [ bleep ]. Go get him. Go get him, now. Who was Todd Caldwell talking about . Turned out there was someone in seth and lisas life that had everyone worried. Things were escalating. You mind helping us out with a little taste test . Which one of these do you think is v8 . Red.

Reporter lisa techel was dead, murdered in her own bed. Her distraught husband seth was outside, shirtless and barefoot. When lisas little sister your best friend. Reporter seth was inconsolable, and acting out. I went over to him when i first got there and i tried hugging him. He pushed me away. He punched his truck, and i said, dont do that, seth, you know, let me see your hand. Reporter todd offered to take seth back to his house, but doug techel knew this was a moment his son should be with him. It was just bad. I mean, it he was sobbing. And we just hugged and cried. Reporter marty wonderlin, working his first homicide, was the first deputy to speak to seth. Howd that go . You know, i ask him what happened. I came running out. And i looked in the bedroom and shes laying there. Reporter through the overwrought husbands sobbing, a story started to emerge. He basically tells me that he was in the shower gettin ready to go to work, and he hears a gun go off. I ripped open the shower curtain and i grabbed my towel i didnt see anybody down the hallway. Im gonna kill whoever the did this. Reporter theres been some sort of an intruder. Yeah, thats what hes tellin me, that someone came in while he was in the shower, shot lisa and ran away before he could catch him. Well figure it out, brother. I cant tell todd. Well figure it out. Reporter lisas father todd thought hed figured it out and already had a suspect. That go get him. Go get him. Now. Reporter todds rage was directed at the neighbor on the other side of the fence topped with barbed wire, a 56yearold disabled army veteran named brian tate. I just remember saying, go get him. Go get him now, and i thought, they better get to him before i do. Reporter brian tate had been embroiled in an escalating feud with his neighbors lisa and seth. Certain his daughter was now dead because of it. This is this culmination of bad bloods been goin on for a months time or more now . Right. Uhhuh. Reporter it started about two months before the murder. Seth pulled a dead deer off the road along the property line. Brian tate later tossed the hide onto seths property. Seth tossed it back, and the battle was on. Tate made several calls to the county, complaining about nasty acts of vandalism. Todd caldwell responded to one in april. And tate pointed the finger at his young neighbor. I cant remember names. Seth, seth techel. Seth techel . Yup. Torkel . Techel. Techel. Yeah, his dad owns champion bowl. Okay. And ill tell i just theyre good people. They really are. Reporter now this guy, brian tate, does he know that youre the fatherin law of the neighbor . No, and i dont wanna tell him that because i dont want that to affect maybe what he does or doesnt do. Reporter and he thinks thats the source of his trouble . Right. Reporter those people over in the trailer property across the way . Yeah. With it. What if what if what if im the one whos gotta catch him . Reporter brian tate told todd that dog feces and rocks had been hurled at his home. He then showed todd the evidence. He described the vandalism of his home in stark terms. He says that he thinks these are acts of terrorism and, you know, kind of a bell goes off like, terrorisms kind of a weird word to use. And the whole time half the time, i guess, hes sitting there. Hes i notice a shotgun layin on the ground, you know . And im like goin that makes me feel a little reporter does that make you a little twitchy . Yeah, yeah. Exactly. Reporter so twitchy that todd sent a headsup email warning fellow deputies about tate, that he might be dangerous. Im thinkin, i dont wanna be the reason a deputy goes out there and gets hurt. Okay, if you go out there, be careful. Tate might be 1096, which means mentally, you know, challenged. Reporter in fact, tate did illness. Hed been diagnosed as a paranoid schizophrenic. Seths mother lorraine, a social worker used to dealing with mental patients, was worried and talked to both seth and lisa about their neighbor. She was terrified. This was when things were escalating. They thought that they could, you know, handle whatever. And um but they they were fearful. I was fearful. Reporter on may 15th, just 11 days before lisa was killed, an agitated tate made another call, complaining that the vandalism the terrorism was getting worse. Todd responded again, this time accompanied by fellow deputy don phillips. Im trying to have a conversation with you. You know it . I dont wanna be yelled at either. Well, im trying to have a conversation with you and i dont understand why youre walking. Youre raising your voice at me. I, youre right. I am. What im wondering because youre not listening. Reporter did you think he was a risk, that this was yeah. Yeah. Reporter a guy who was capable of flipping out . I i did. Reporter and now, lisa was dead, and the trailer was a crime scene. Marty wonderlin, the first deputy at the scene, already knew all about brian tate and had zeroed in on him as his candidate for prime suspect. All the direction is heading across the fence to this guy whose name is brian tate. It is. Reporter and police decided it was time to pay a visit to tate. They armored up and got out their long guns, not knowing what their suspect might do. If youre ballsy enough to break into a house, shoot lisa and make it back out, youre ballsy enough to do just about anything. 3 f2 a continuacio n la polici a loaded. Copay before you fill.
