discover what he termed his mother lode. information that covered from the otero murders all the way through dolores davis. >> there were journals and drawings. he had materials that he collected from each of his victims. clothing, car keys. >> he had compartments everywhere. he had false bottoms in a closet. he had stuff in a crawl space. he had stuff in a tree house he had made for his kids. also there were polaroids of himself in his autoerotic activities that the police initially thought were male victims that they didn't know about. >> what we would discover is photographs of himself where he would be dressed up as female. sometimes he would have a mask on and a wig and he would be tied up. >> he was dressing himself up in bras and underwear, torturing himself, hanging from trees, taking photographs of himself half buried with a polaroid camera that he'd hook up to this foot and pull the trigger. >> he took thousands of pictures with that polaroid.

>> he took the photos of himself to relive the experiences. that was part of what he needed to be aroused. >> reporter: what did you make of all that? >> horrified. to have somebody that seemed so prim and proper, to find out that was his other side, that was just weird. like, remove all the crimes. just that is, like, shocking. >> serial killers have a pattern. usually they're abused as children. he flatly denied any physical abuse, sexual abuse. all of the hallmarks of a person that turns into a serial killer, he claimed he didn't have. >> he always had a very, very healthy fantasy life. rader had, at a very young age, connected sexual excitement with violence. >> in november 1959, about 200 miles west of wichita in a town called holcomb, kansas, a family of four was murdered, tied with ropes first. dennis rader, at the age of 14, was in a car with a girl he had

a crush on. >> the murders of four member of the herbert cliutter family -- >> he heard this on the radio, this alarming story of the clutter family being murdered in their homes, and he immediately wanted to kill the girl that was in the car. >> the "in cold blood case" in kansas is so shocking, they make a movie out of it. >> make one move, holler once, and we'll cut their throats. >> to dennis, it really taps into his fantasy and obsessions. >> his reaction was not horror as most people's were, it was arousal, attraction. he wanted to do that, too. >> were there things in katherine ramsland's book that angered you? >> yeah, the book was very personally difficult to read. >> rader said that his wife one time came home unexpectedly and witnessed him in her slip, hanging himself, or at least preparing to do so.

he tried to explain it. and he says she went to a counselor and was reassured this is sort of a man thing and it wasn't necessarily dangerous or terrible. but she wanted him to keep it out of the house. just don't do it in front of me. >> i called her. i said, look, he's claiming this thing in this book that's about to come out. i'm like, did it happen? she's like, no, no, no, no. she said, like, no like five or six times. so then it becomes this issue -- who are you going to believe. are you going to believe the sane normal woman which is my mother, or are you gonna believe the narcissistic psychopath that you know lies all the time? >> rader does have a lot of psychopathic behaviors. we know from brain research that they have very shallow emotional roots. so he doesn't have a conscience about lying or deceiving or manipulating or pretending to be somebody he's not. >> when you try to sort this out, is your dad mentally ill,

or is he evil? >> he's definitely mentally ill, but he's not insane. he very much knows what he's doing and what he did. >> he's just a sick, sadistic murderer, is what it comes down to, not some fascinating criminal. >> i think to dismiss dennis rader or any other serial killer or mass murderer as a one-dimensional being is to make yourself unsafe, because you will not spot the real monsters if you think they're so easy to see. >> early on, when my father wrote me in 2005, he said, like, he's so sorry things got away from him and, like, cat and mouse caught up with him. you will always be my baby girl i raised right, proud, independent. hopefully someday your heart will mend and you can forgive me. life before the arrest was a good time, and the dark side took me away.

>> reporter: how could you even correspond with him. i mean, people would wonder like, why wouldn't you just cut him off? >> i wasn't corresponding with btk. i'm never corresponding with btk. i'm talking to my father. i'm talking to the man that i lived with and loved for 26 years. i still love my dad today. >> reporter: you still love him today? >> because i love the man that i knew. so, you know, clinically there's, like, criminologists or psychologists that would say, your father's a psychopath and he's incapable of feeling. but i don't know -- i don't know a psychopath. that's not the man i knew and loved. so, like, i -- i have a tendency to want to compartmentalize and disassociate and say, over here for 26 years, this man that i adored and loved that could sometimes be gruff and a couple times was abusive, and that's not okay. and then over here is this insane, torturous, violent, horrific man.

while you were reading. >> you were trying to discover someone. >> dennis grew up watching kake. he watched kake every single night. we were his favorite station. >> and good evening, everyone. we begin tonight with breaking news in the case. >> we have learned that rader has been charged with ten counts now of first degree murder. >> the day he was caught, the weekend weather guy walks into the newsroom, his name is jeff, and he goes, susan, i have to apologize. i said, apologize for what? i'm a member of christ lutheran. dennis rader asked me, hey, can we take a tour of the kake studios? and jeff, our weekend weather guy is saying, i brought him into the kake studios as a tour group. and i'm looking -- that was him. that was him taking the pictures. dennis rader was right there, five feet from us, watching the newscast two months before he was caught.

and the weird part about it was -- you know during the two newscasts, we were btk, btk, btk, because we were that whole year. can you imagine how that thrilled him? >> it was nearly a year ago when wichita got a reminder. >> okay, we know he's charged with ten murders. >> everybody wanted to talk to dennis, from the national media and international media on down to those of us in the local media. of course, i wanted to talk to dennis rader. i wrote him a number of letters, and i had included my phone number. then on one saturday morning, i get a call. the operator says, will you accept a collect call from the sedgwick county detention facility? i had btk on the phone. >> i have a recorder going if that's all right with you. >> okay. sure. >> i said, there are questions that i want to ask you, and he said, go ahead. >> when did you first know that you had a problem? i was always curious when he knew that he was going to become something very bad in life. >> this was a building thing.

this -- that started many, many, many years ago. >> can you pinpoint when you knew that there was a problem coming? >> well, i would say probably even when i was in probably grade school i started having problems. >> and what kind of problems were those? >> oh, sexual -- sexual fantasies. mine was probably just a little bit weirder than other people. >> he said, by the time i was in junior high, i knew who i was and i knew what i was. >> the first thing that set btk apart was even before he started to kill was his desire to be a serial killer at a time when that phrase wasn't even in use. there's very little media coverage of these people. but he was reading true detective magazines that showed him a couple of serial killers that then became role models for him. so he incorporated serial murder into his fantasy life.

>> he talked about the hunt. >> the hunt for that object, it was more of a high, i guess, than it was actually them. >> he told me he got a high from it. finding the woman and then killing her, that was what turned him on. do you have any remorse over the killings? >> yes, i do, i do have a lot of remorse for them. i feel sorry for them. >> dennis rader told me he felt sorry for the victims. well, no one believes that. the families certainly don't believe that. police department doesn't believe it. the fbi doesn't believe it. it was just him trying to be human. >> it was more like he was sorry that he got captured, or it's more like he's really sorry that he's in prison and he's cold and he doesn't have my mom's cooking. honestly, i don't ever really have saw it where he said he's sorry for murdering ten people. >> when you add in for rader the narcissism, it's always going to be about him.

narcissists have a strong buffer around themselves that is only about them, and they'll always act first in their own interests, always. >> virtually everything involving dennis rader and the media can be traced back to his arrogance. he wanted attention. attention drove him. >> his hunger for publicity seems to have done him in. would he have been caught had he not re-emerged in 2004, had he not sent out those envelopes to the paper and to the tv station? if he faded into the night, would he still be out there in wichita living as a married man and a father and a dog catcher? >> i think bottom line is i want the people of sedgwick county, and the united states and the world to know that, yeah, i am a serial killer. you know, i'm going to pay for it with a life sentence. >> after i hung up the phone, i remember thinking, i've just talked to a man who has no soul.

>> please rise. >> now dennis rader was headed to court. >> all right, mr. rader, i need to find out more information. >> we've never heard a serial killer like this. >> the kids were really banging on the door, hollering and screaming. >> it was shocking. >> this gets complicated. let me think now. >> our mouths dropped. for severe eosinophilic asthma. nucala reduces eosinophils, a key cause of severe asthma. nucala is not for sudden breathing problems. allergic reactions can occur. get help right away for swelling of face, mouth, tongue or trouble breathing. infections that can cause shingles have occurred. don't stop steroids unless told by your doctor. tell your doctor if you have a parasitic infection. may cause headache, injection site reactions, back pain, and fatigue. ask your doctor about nucala. find your nunormal with nucala. we're here for the heavy flow-ers and the wedgie-pickers ask your doctor about nucala.
