♪ welcome to "very scary people." i'm donnie wahlberg. after torturing and killing seven people, demented serial killer btk contacted police to boast about his brutal acts. he threatened more victims would follow. his real identity was still a complete mystery. he dared cops to find him. the city of wichita was on edge. wichita police form a secret task force of seasoned detectives to track down btk. they need to capture him before he kills again. here is part two of "btk: the taunting." ♪ ♪ hatteberg: wichita, kansas, was in the middle of america, and nobody locked their doors. it was a great little town to be from. jordan: the morning of january 15, 1974, was just a regular school day in the otero household -- until the unthinkable happens. an intruder enters their home and commits atrocities against this innocent family. i saw my parent's bodies -- it just felt like somebody had ripped my chest wide open and pulled my heart out. jordan: and investigators are trying to piece together the evidence and find the killer when, in april, another brutal killing. otis: when the crime-scene investigators found the dna stain on the female clothing, they collected it, but there was no dna testing at that time. and so they packaged it properly, sealed it up, and put it with the rest of the evidence. and wichita instantly changed. it wasn't an innocent city anymore. killer breaks in. he's lying in wait. and he's thinking he will be able to subdue her and do whatever he wants and fill his fantasy. btk studied a lot about police techniques. he knew that the police, basically, were looking for a common m.o. the btk nomenclature -- "bind, torture, kill." and that's how he wanted to be known. so he then sits down and creates a very elaborate letter that he will then send to kake-tv. the writer, who claimed to be btk, admitted to the murders of the otero family, shirley vian, nancy fox. he admitted to and gave details of all of those homicides. we have an individual who apparently has the uncontrollable desire to kill at times. this individual is responsible for seven murders in our city. nobody knew where, when, why, or who was going to be next. ♪ ♪ ♪ the idea behind the ghostbusters was to have people that didn't have any impressions of the investigation up to that point, who can put some fresh eyes on it. gagliano: you're gonna look at it from, "hey, do we need to go back and out and reinterview people? could we possibly have interviewed somebody with important information and we missed it?" the first part of the ghostbusters was just getting the case together. the case was all over the police department. it was in boxes, it was in folders in people's houses. the ghostbusters brought order to a dispersal of records. brady: part of the work was establishing a department database. we would look at, for example, there was a certain gun which was used in one of the killings, and so we did research on all of those kind of guns, found every person who ever bought such a gun in the united states, and that went into a database. the fbi said, "there has to be a pattern to these crimes." one of the detectives thought that the killer was choosing certain house numbers to kill people. i built a database for them that tracked how far, let's say, sex offenders lived from crimes. o'connor: they did a fantastic job. i mean, they ran down leads. incredible leads. they never gave up. they tried every lead. it was just -- they just ran out. the leads ran out. i wondered if there is a pattern. "why can't i find it?" the point is, these killings were random. there was no pattern. he would see somebody, decide, "i think i'd like to kill them." there's no connection between the victims, there's no connection between addresses. it's all random. ♪ rader: she was chosen. i went through the different phases, the stalking phase. and since she lived down the street from me, i could watch the coming and going quite easily. jordan: after a seven-year hiatus, a very long cooling-off period for a serial killer, btk resumes in 1985 with the killing of a 53-year-old woman named marine hedge -- a neighbor of his who actually lived right down the street. he will cut the phone line. he will enter the house. and he will wait for her to come home. she didn't come home for quite a while, and when she did, she came in with a man, and the two of them were talking. o'connor: they hang around, watch tv. he grows impatient as he sits in a closet or something, waiting for her. eventually, her date will leave. she'll go to bed. and then he comes out, surprises, shocks marine hedge, and kills her. jordan: this one was different, however. after he strangled her, he removed her body and transported it from her home to the basement of the local lutheran church. he poses the body. he photographs it. he's going to save those souvenirs for later. and then he throws her body in a ditch, so much like a piece of trash. so his m.o. is actually shaping and changing and morphing over time. singular: this is a change again in his m.o. because he was also selecting an older victim because he was now older, and he wanted to be able to physically control the person. ♪ jordan: btk's next murder occurred in 1991, with a 62-year-old victim, dolores davis. ♪ rader: i had cased the place before, and i really couldn't figure out how to get in, and she was in the house, so i finally just selected a concrete block and threw it through the plate-glass window. ♪ [ glass shattering ] he didn't mess around on this one. he just threw a big block through the window while she was sitting there reading. and he'll attack her and kill her, remove her. he will take her to a bridge out in the county, under the bridge, where it will become light. he's running out of time, so he has to leave her, and he will come back the next night with a mask that he will put on her, and he'll take pictures. that body is discovered by a boy waking his dog the next day. jordan: by this time, he's been killing for almost 20 years or so, but now he's in his 40s. he's aging out. he's learned from his crimes. he's been fought against, overpowered. he has made a lot of mistakes. he wants to make sure he still gets away with it. ♪ at pnc bank, you can find us in big cities and small towns across the us, where our focus is to always support the people who live and work there. because you call these communities home, and we do too. pnc bank. lowe's knows a style refresh is even more refreshing ...when it's at the right price. that's why, we've we pull our favorite looks together in-store and in in the app. so it is easy to get the look you want for less. you got this. we got you. amazon has great deals on everything kids need. instead of spending more, he spent less. seemed obvious. why would a person spend more money? he's eight and he gets it. i'm 10. well, that's less impressive. with the new straight talk multiline plan... ...more lines mean more savings. get unlimited data, talk and text for just $25 dollars a line ...all on nationwide 5g. plus, no hidden fees. no contracts. no compromises. that's the straight talk talki'' from straight talk. available at walmart and walmart.com. are we a reflection of our places in life, or are they reflections of us? could we have been somebody else if we had taken a right turn instead of a left? or if we had taken the place with the hot tub or the one uptown? we went downtown. could we be fabulous or fantabulous? yes, yes. we sure could. with apartments.com's multitudes of listings, our possibilities and yours, are truly multitudinous.

"if anybody's gonna tell my story, i'm gonna do it." hatteberg: when he saw that story, he decided, "i'm back. i'm starting up again." nobody in 2004 expected that. roehrman: so, a little while after the eagle had its story about the 30th anniversary of the otero deaths, a letter came into the newsroom, and the return address was bill thomas killman, the initial as in "btk." inside were three pretty blurry photos of somebody lying on a floor and a driver's license. otis: my partner, dana gouge, and i are sitting in the homicide unit, working on cases. a captain came up to the unit and was holding an envelope in his hand, and he said that a reporter from the eagle newspaper said, "this is a weird letter we got at the paper. it appears to have a photocopy of three polaroid pictures of some female laying on the ground inside of a house." i will never forget when dana gouge opened that letter. he looked at what he had in front of him, he slid it across the desk to me, and there were three polaroid photograph photocopies of vicki wegerle laying dead in her home. also, with those three polaroids, was a photocopy of her missing kansas driver's license and the initials btk. that symbol was not out in the public. and seeing that btk symbol on a piece of paper with pictures of vicki was bone-chilling. ♪ singular: about a week later, lieutenant ken landwehr, who's in charge of the murder investigation, has a press conference. the wichita police department on friday received information from the wichita eagle and received a letter in the mail -- referenced the homicide of vicki wegerle on september 16, 1986. the letter contained copies of photographs and a personal item of ms. wegerle. we've also been able to determine that this communiqué most likely came from btk. we begin tonight with a killer on the loose, a madman still out there taunting police and reporters. he's known as the btk killer because he binds, tortures, and kills his victims. for more than 30 years, wichita has lived in fear of those initials, and tonight it seems he has surfaced yet again, sending new clues about who he is and the lives he's taken. peters: we were scared to death. it was a total replay of when he was killing in the '70s. was he still killing right now? and who was gonna be next? ♪ ♪ (don't cha by callaway/ray plays) ♪ ( ♪ ♪ ) don't cha wish your phone was fun like this?

"go to the corner of this street and this street, and you will find a cereal box under a stop sign. in the cereal box will be another clue." well, we sent a reporter right out there. sure enough, there was a cereal box. inside of the cereal box, there were several things, but the most disturbing thing was a doll, almost like a barbie-type doll, bound the way that btk had bound the little otero girl in the basement. ♪ we're all very seasoned homicide detectives, and we were all shocked. recent communications from btk have included several items of jewelry. there was jewelry included in the post toasties box that was left on north seneca street, as well in communication number 7, in the package received yesterday by ksas fox 24. otis: the postcard in there talked about some of the crimes and also commented that the media or the police haven't talked about the home depot drop he made. btk had pulled into the parking lot of a home depot, put a cereal box in an employee's truck bed. the employee found it, called dispatch, who called me, and we went and recovered that, and it was more taunting with dolls and stolen jewelry. on the plus side, home depot had cameras covering their parking lot. they had to shut down their store and their system in order to obtain videotape. you can't see him, but you can see the car come in, you can see an individual get out of the car, and then you can see something being placed in the pickup of this employee, and then the car drives off. detective relph, who knew a lot about cars, tried to identify the car. we had captured his vehicle at a home depot, and we knew from the photograph that he was driving a jeep cherokee. that was the very first piece of evidence from btk that we got on our own, that wasn't given to us, and that was a huge breakthrough. ♪ this is how tosin lost 33 pounds on noom weight. i'm tosin. noom gave her a psychological approach to weight loss. noom has taught me how you think about food has such a... huge impact on your relationship with it. visit noom.com and start your trial today.

what kind of background or history does this person have? what kind of twisted life has this person led? singular: dennis rader was born in 1945 in kansas, and his family then later moved to park city, kansas. he had three younger brothers. he was the oldest, and that was very important to him in that he thought of himself as a very responsible son. we don't have any evidence at all that he was horrifically abused. he had married parents. as far as we can tell, nothing bad ever happened to young dennis rader. at the same time, he had early on this penchant for doing a couple of things that were somewhat unusual. someone in the family had these true detective type magazines from the 1950s, where you would see women on the cover. maybe they were tied up, or maybe they were looking at an attacker who was off-screen in horror, and he was exposed to them, and he found them stimulating. he started making drawings of sort of mummy-like figures where there would be women with lines across them, as if g ed up. o'connor: he talked about, from a young age, some family members being out on a farm where they had killed a chicken, and that chicken had to be tied to a stump before they cut its head off, and he described being aroused by that. jordan: he was aware from a very young age that he had these sexual fantasies which were completely abnormal, that he was what outsiders would call perverted, that he had paraphilias and urges that nobody else shared, and he fostered them. he didn't talk to others about them. he never went to a psychiatrist or a psychologist to try to figure out where these urges were coming from. he simply harbored them and knew that, some day, he would act on them. ♪ is a new title really necessary?

"hello, mr. landwehr." "hello, mr. rader." landwehr says, "do you know why you're here?" he says, "i have a pretty good idea." otis: we had staged the interview with dennis rader far in advance of him being in that room. we had a camera and obviously audio and video recording going on. morton: literally, in 3 hours and 15 minutes, it got to a point where ken was finally talking to him about dna and where we could get dna from. he basically said, "well, you got me," and he still wouldn't say it. so i finally looked at him and said, "come on, dennis, just tell us who you are." you're btk. okay. we begin tonight with breaking news in the case. we have just learned that dennis rader has now been booked into the sedgwick county jail. peters: rader has been charged with 10 counts now of first-degree murder. today is a very historic day for the wichita police department. btk is arrested. [ cheers and applause ] relph: once he was caught and they did the search of his house... ...then in the crawlspace area, he had a big ziplock bag that had stuff from dolores and marine, and he had several polaroids. o'connor: he had things in his home, and that's why people had speculated, how could the wife not know? and it's because most of the stuff was behind false drawers or false walls, so hidden. otis: he told us about the cabinet in his office. the top drawer was work stuff. we opened the bottom drawer, and it was full of btk memorabilia -- newspaper clippings, some of his original pictures, some of his original 1970s letter to the cops. he called it "the mother lode." foulston: he was really prolific. he used to take photographs of himself. he would half-bury himself. he would swing from trees. he would put masks on. he would put women's clothing on. it was despicable, disgusting, sexually bereft-type of stuff that you have never seen in your life and you don't ever want to see again. and that was all involved with that case. in our minds, as this was discussed and kind of profiled down at the behavioral science unit, was really his art. and he does a lot in what we call the expressive style. he really likes that. o'connor: he actually entered pleas of guilty to the 10 homicides, and so judge waller had rader describe the murders at his guilty plea, and i believe dennis rader was more than happy to describe what he had done. man: when you went into the house, what happened then? well, i confronted the family. i pulled the pistol, confronted mr. otero. otero: that day we went to court, and we listened to the testimony about how my family was killed. it was very, very hard. i didn't have a mask on or anything. they already could i.d. me. it was once again that feeling of my chest being ripped open, had come back to me. and made a decision to go ahead and -- and put 'em down. otis: he recited them like he was reading a book. ♪ and that was spine-chilling. otero: everybody asks me, "do you forgive him?" all i can say is, i can't lie to you -- no. as far as, like, his punishment goes, i hope he lives a long, rotten life. you know, i don't forgive him. i know that's a problem i have as a christian. the lord knows how i feel about it. when i hear the name "dennis rader," the first thing that comes to mind is disgust. dennis rader has never really truly apologized for anything he's done, has never truly apologized to the victims' families, has never, i feel, felt remorse for what he did. otero: it was a great family. my mom was great, she really was -- and my dad. and that's why, when i do these interviews, one of the reasons why is just, for one instant, my family, who've been gone for almost 40 years now, they're relevant again in today's society. they existed, and the world knows they existed, and they didn't just get erased from life and swept under the carpet. they were somebody, and they were worthy of life, you know? and, to me, that's important. o'connor: dennis rader was sentenced to 10 life sentences, all run consecutive to one another, so he'll die in prison. he is in the el dorado correctional facility. foulston: the first question that people would ask, "why can't you get the death penalty for him?" i'll say, "oh, because there was no death penalty for those times and places where these incidents occurred." this was somebody that should not have lived. i wish we'd had the death penalty for him. after what he did? o'connor: he liked what he did. it may be something that's hard for us to grasp, why a person would want to do that, but he enjoyed it. it wasn't his parents' fault, wasn't society's fault. he just liked doing what he was doing and wished he could've done it more. it's what he wanted to do, it's what he wanted to be, and if he had his choice, that's who he would be, not the dennis rader the husband/father/compliance officer. he wanted to be btk the serial killer. after dennis rader's arrest, his wife was granted an emergency divorce. over the years, his daughter has exchanged letters with her father, searching for some kind of explanation for his horrible deeds, if something violent happened to him during his childhood, but rader has always insisted he was never physically or sexually abused as a child. lieutenant kenny landwehr was determined to get his man, and he did. many credit him as the reason rader was finally captured. a true hero, landwehr died in 2014 after a battle with cancer. i'm donnie wahlberg. thanks for watching. good night. ♪ ♪ ♪ gacy: to me, clowning was a way of relaxation for me. you regressed into childhood. you were able to relax. and you could be goofy if you wanted to. and still, you had the facade of your face being covered.
