Reporter there is a letter written more than 60 years ago. A prophecy . Perhaps. A warning, certainly. A doctor writing about a very troubled 10yearold boy, suffering from hostility issues, sufficient to produce a personality decomposition and possibly even schizophrenia. The troubled little boy . His name is well known. Robert durst. By now, youve heard the bizarre saga. The multimillionaire scion of a new York Real Estate empire. The disappeared wife, the dead friend, the dismembered neighbor. Hes been the subject of several dateline episodes and the star, though not in the way he intended, of hbos the jinx. But do you . Does anybody know the truth about robert durst . The trail we followed, the revelations we encountered, the personal account he wrote and we were given, which have led us into a very weird place, the lost years of the infamous robert durst. The tale is like quicksand. It sucks you in. Bob is endlessly fascinating and and always surprises me. Reporter he has certainly been elusive, mercurial, sometimes desperate, and always in motion. Well track him, his descent, his strange detour off the road and off the grid. A life that no one, not even his family or close friends, could fathom. He has a good heart inside, i really think so. Reporter we begin with two people who have known and loved the man they call bobby, godfather of their son, close friend of more than 40 years. Long before the rest of the world heard of him. And when did you meet him . We went to high school together. Reporter stewart and emily altman spoke with us for the First Time Since durst was arrest. Theres still a side of bob thats not a monster. Yeah. You know, he has a heart, but its caused me a great deal of conflict and i cant get my head around is whatever happened to bob. Its hard. Reporter the altmans shared personal photos and the story of bob theyve lived and breathed, starting with the family disaster that tormented him. His mom committed suicide when he was 7 yearsold and it was a devastating experience for bob. Reporter compounded by bobs strained relationships with his brother douglas and his father seymour. But then, in the 1970s, stewart introduced bob to a young woman and this whole twisted tale was set in motion. I was living on east 52nd street on the second floor and kathie was living on the third floor, and bob owned the building. He used to come and collect the rent. Reporter kathie was kathie mccormack, stewarts young and beautiful upstairs neighbor. It was like prince charming and a princess. Kathie was the love of his life. Reporter but it didnt last. A few years later, the altmans watched their prince and princess grow she became more independent. It wasnt the fairy tale anymore. Reporter no. In fact, kathies brother jim told us it was more like a horror movie. Theres a dark side of bob that, you know, was fairly well camouflaged when they were first, you know, going out and getting married. But it escalated ultimately into psychological abuse, economic abuse and physical abuse. Reporter remember that doctors letter warning that the 10 yearold bob suffered from severe hostility issues . Kathie gave a copy to her friends, including ellen strauss. Evidence, she said, just in case. Kathie warned all of us that if anything ever happened, look to bob. Bob did it. Dont let him get away with it. Reporter and then in 1982, kathie durst disappeared. How did he take it . Its bob. You know, he asked if we had seen her, if we heard anything, if we knew anything. Reporter but they didnt. No one did. Bob was typically almost detached in his demeanor. You know, almost, i dont know nothing. I dont know anything. Reporter from the outset, bob denied any involvement in kathies disappearance and still does. At the time, he was careful to distance himself from investigators. New york times reporter Charles Bagli has covered the durst real estate empire for three decades. And when kathie vanished, said bagli, bobs protective friend susan berman, a name youve probably heard of, became his unofficial spokesperson. And susan would call back and say, well, bobs, you know, really not feeling right right now. Im going to handle a lot of this. Reporter bob, himself, was pretty much incommunicado then. But we have obtained this, his own account. His version of things which he wrote later. Heres what he wrote about kathies disappearance. After my wife kathy left, my compulsive use of alcohol, drugs and food changed from an infrequent problem to a daily event. He didnt come in to work for about two years. Reporter later, when bob began showing up at work again, sporadically, he wasnt anything like a buttonedup executive. He enjoyed smoking pot in a social situation, burping and farting because it disturbed people, you know, and he liked to watch their reactions. Reporter right. So, these stories about misbehaving, peeing in a wastebasket or something, thats there was peeing in a wastebasket and all of that. It gave pause to the family. Reporter and it was no great surprise when the family patriarch, seymour durst, chose bobs younger brother douglas to run the family business. Did he really think, up until the point where douglas was picked, that that he had a shot at it . He was groomed for it. That was supposed to be his his job. He was upset. It had a devastating effect on bob. Reporter and that is when the little known and reclusive bob durst went off on his own, to embark on a strange new life.

He told me he was a writer for the wall street journal. He said he wanted to have a place with an ocean view. Reporter bob forked over nearly 400,000 in cash for a big family house in the town of trinidad, overlooking the pacific, where he lived like a hermit. Nobody really seen him around. He never really had contact or didnt really have any best friends. Reporter in that personal account of his, he explained why. I hated to have more than a brief conversation with someone because i immediately found myself being asked, what do you do . The true answer was nothing, i live off the family estate. Which was true enough, but he wasnt exactly idle, either, said author Matt Birkbeck, whos been following the durst case for over 15 years, and wrote a book about it called a deadly secret. Bob durst was buying other properties, he said, but some of his choices didnt seem to make sense. These arent just homes. Were talking Storage Facilities and p. O. Boxes. Reporter you mean hed buy one Storage Place or something . Hed have an address and the address turned out to be a storage facility. And whats he doing with all these different Storage Facilities .

He would buy something pretty plain like this, you know, nothing real you know, so he it wasnt outstanding. And then he would get a skirt, you know, and try to match it up, you know, and most of the time, he couldnt. So i would try and help him match. Reporter kay had seen her share of crossdressers, but there was Something Different about this one. He wanted to be somebody else besides robert durst.

Reporter or los angeles, where hed look in on susan berman, who youll remember spoke for him after kathy disappeared, and was now trying to make it as a hollywood screenwriter. She and bobby i always felt were very tight. Reporter this is Susan Bermans friend kim lankford. She was very protective of bobby. Reporter susan lived in a slightly rundown cottage in l. A. s benedict canyon, and occasionally bob would stop by. But, like a gypsy, would soon be gone again, sometimes flying back to trinidad, where hed question his shuttle driver ross vitale. He would kind of specifically ask questions about, has the Sheriffs Department been out here . You seen anything going on . Reporter and in 1997, while bob lived here, something did happen. A local teenager named Karen Mitchell vanished after leaving a womens shoe store that, later, bob was known to frequent. By the year 2000, the case was cold. But that, of course, is when, across the country in new york, another case was suddenly hot again the investigation into the disappearance of bobs wife kathy, reopened by Westchester County d. A. Jeanine pirro, who later became a host of fox news channel. I had an instinct. Everything about this reeked of murder. We had evidence that she was battered by him, which he has since confirmed. It was clear to me that he killed her. Reporter the investigation was supposed to be top secret, but, as we know, bob durst found out. Yeah, he seemed worried, he did. Reporter and then one of kathys friends youve met her, ellen straus offered the cops a tip. I begged the police to interview his best friend susan berman. I showed them all my research.

Reporter by the autumn of 2000, Westchester Countys reinvestigation into the missing millionaires wife kathy durst had been chugging quietly for months. When the story broke, durst found himself in the media glare again. It had been 18 years since kathy disappeared and public opinion, he wrote, turned against him unlike before. In 1982, the tone of the publicity was of a scandal about a rich schmuck who had a terrible marriage. People did not distance themselves from me because of it. In 2000, i was a murderer who everyone disliked. Of course, susan berman had kept the bad press at bay back in 82, but now, investigators wanted to talk to her. And what did bob do then . He got married. Not to susan berman, but to new York Real Estate broker deborah charatan. That wasnt a marriage made in heaven. That was clearly a marriage of convenience, in that this is bobby durst saying, in the event im arrested, i have someone to bail me out. And to handle my affairs. Reporter well, of course thats just an opinion. Maybe it was a love match. But it did come with spousal privilege, which meant deborah didnt have to talk to the cops about her new wealthy husband. She also reportedly got access to a substantial share of his money. Deborah doesnt do anything unless deborah benefits. Reporter thats a character reference im not sure id want to have. She is a savvy business woman. Reporter meanwhile, out in hollywood, susan berman was struggling to make it as a screenwriter. Things werent quite going as well as she would have liked with her career. Reporter for years, susan had relied on bob for help and he responded, sometimes with big checks. Two at least for 25,000. There was some macabre kind of kooky energy that went on between them. Reporter we got some unique insight from a woman who claims she was Susan Bermans closest confidante and therapist and psychic. Her name is barbara stabiner, and she told us she knows what susan was thinking. In fact, she gave the police many hours of her recorded conversations with susan, in which, during those last months of 2000, according to barbara, susan grew increasingly worried. Did susan ever tell you that she was afraid of robert . She did tell me she was fearful of him, because i had the feeling she felt afraid of him because she was afraid he would withdraw any help. Reporter but it was more than that, said the psychic. Susan was afraid of bob, she said, because she knew too much. She knew his secrets. Towards the end of her life, she was very agitated with him. Reporter would he save her . Susan didnt know, said barbara. And then, just before christmas 2000, she said susan let her know that bob was on the way with money. He said, ill bring it. And thats what happened. But i cant prove it. Reporter l. A. Cops have long suspected bob did go to susans house in l. A. But not to bring her more money. To prevent her from talking ever. We do know from flight records, and bobs own personal account, that he did go to california. Christmas 2000, robert durst was on the move again. Late december, he flew here to eureka, california. He had owned a house in this area for several years, but had recently sold it. He wasnt coming to stay here. He got a car, got inside it, pointed south. In bob durst s own personal account, he notes a visit to garberville, 600 miles from los angeles. After that, we cant follow his trail. We do know that late on december 22nd or early the 23rd, susan berman was murdered by a bullet to the back of her head at her home in l. A. And on the 23rd, flight records confirm bob took off from San Francisco on the red eye to new york. And soon after, this letter postmarked december 23rd, showed up at the Beverly Hills pd. I call it the cadaver note. Reporter ah yes. The famous note directing police to her body. A note, likely written by her killer. Word of Susan Bermans murder traveled fast. It was like, oh my god. I mean, and i my first thought was, why didnt they listen to me . They did not interview susan berman in a timely manner. What were they waiting for . Godot . Reporter bob skipped Susan Bermans memorial service. And a few weeks later, he surfaced in galveston, texas, another good place to get lost, except, of course, trouble eventually found him there. A killing, a dismemberment and an unforgettable acquittal. We all know the story, but not this version. Coming up, did robert durst rehearse telling the truth . His wife and friend smuggled a little cassette tape recorder into the jail. He would discuss with them whether or not he sounded believable with the story he was telling. When dateline continues.

Reporter at the end of the highway to galveston, texas, is a road sign. Mile zero, it says. This is where bob durst went to vanish. He had actually moved here just weeks before Susan Bermans murder. And, initially, he was not a suspect, but he took pains to keep himself hidden, as he told his friends the altmans. Nobody would be looking for a robert durst in a 300 a month apartment under an assumed name. Reporter the name of an Old High School classmate named Dorothy Ciner. Although in his log, he wrote that he didnt like wearing a womens wig. It itched, it got in my eyes, unless it was on tight, which made my head sweat. But the version bob has told over the years, believes author Matt Birkbeck, doesnt tell the real story. Certainly not of the famous killing of his elderly neighbor morris black. Or of bobs activities in galveston and elsewhere. It was really strange, you know, him and black, palling around in galveston amongst the homeless. So what is a guy of his wealth and his familys influence doing stealing identities . Reporter in fact, in the spring of 2001, at the same time as he, as Dorothy Ciner, was living in galveston, he rented another room in new orleans under the name diane winn. We found the place, and his old landlord, michael ogden. He was wearing a blouse with small brassiere, a wig. Reporter he lived on the top floor and the neighbors often saw him wearing womens clothing. He wasnt a drag queen. He was just in disguise. Reporter and then hed fly off somewhere else, new york, california, connecticut, always returning, as he carefully noted in his personal account, to that downmarket apartment in galveston. Where, in september 2001, he shot morris black, accidentally, and in selfdefense, he claimed, and then dismembered the man and threw his body parts into galveston bay. Heres how durst described it jack daniels. Marijuana. Bought bow saw; bow saw not deep enough, return for bigger bow saw, could not use saw, went back first looked at electric saws, bought axe. Did it. But Matt Birkbeck believes bobs claims about the killing were attempts after the fact to sanitize what the evidence suggests was a brutal murder. It makes no sense. And if you look at the autopsy report, it shows that morris had been beaten severely in the upper torso, and he even perhaps suffered a heart attack. So obviously Something Else was going on. Reporter after his arrest, bob called his friends, the altmans, and tried to explain what happened. He said he went to a fugue state. He was an out of body experience. I its hard to understand. Reporter charged with murder, bob durst also called his new wife, debrah charatan, who helped arrange 300,000 in cash for bail which he promptly skipped, got a car, and traveled the country, sometimes using morris blacks i. D. It was weeks later when they finally caught him, shoplifting in bethlehem, pennsylvania. While more than 38,000 in cash was in his car. The altmans visited him in jail. You know, i asked him how he was doing. And he said, you know, not great. He talked about how he pretty much was gonna do maybe suicide by cop. Reporter but bob, of course, didnt pull that particular trigger and was sent back to texas for trial, where his houston attorney Dick Deguerin devised the defense that beat the murder charge. It was a simple case of a struggle over a gun, and the gun went off. If it truly was selfdefense, then what happened after the killing doesnt change that. Reporter bob wasnt so confident hed get off. In fact, he asked his friends the altmans to help him learn more about what life behind bars would be like for him. He thought that if we got to know the ins and outs, that maybe it would be easier for him once he was on the inside. Reporter he worried about how hed hear his favorite music, for example. He was trying to find out if maybe there was a Radio Station he could buy so that if he were in jail, he could have music that he liked. Reporter bob knew his chances of acquittal depended, in large part, on winning the jurys sympathy. So for that, he went on a crash diet. Bob was trying to use every way within his power to look frail when he was on trial in galveston. Reporter he also went to considerable trouble to practice his testimony, as presiding judge susan criss learned later from recordings taped in the jail. He had his wife and friend smuggle a little cassette tape recorder into the jail. He would practice his testimony, sneak the tapes back to them, and then discuss with them whether or not he sounded believable with the story that he was telling. Will the defendant please rise. Reporter the altmans said bob was convinced, 99. 9 certain that hed be convicted. We, the jury, find the defendant robert durst not guilty. Reporter the jury took five days to save him from 25 years to life in prison. Though he later served a little time in federal prison for skipping bail and dismembering morris black. But by 2005, he was a free man again. Now the only person who could catch bob durst was bob durst. Coming up, what was he thinking . Caught off camera and seemingly offguard on the jinx. Did robert durst confess . Why did he give that interview . Thought hed be able to show hes not a horrible person. When dateline continues. Ir the enamel on a daily basis.

The mess in galveston long behind him, he had settled into this luxury highrise. Mark thuesen was the condo board president. Mr. Durst was mostly disheveled. It didnt look like his hair was kept. It was messy. He looked like a street bum. Reporter he was 67 by then and seemed to have done away with his cross dressing. Might have lived out his days in quiet, if eccentric, isolation. But then the durst story went hollywood. A movie called all good things was released based on Robert Dursts life, played by ryan gosling. It was directed by filmmaker andrew jarecki. Bob liked that movie, and thats why he got involved with jarecki, i think. Reporter it was to offer his side of the story that bob sat for two long interviews with jarecki, for what would eventually become the hbo series called the jinx. I begged him not to do it. I begged him not to do it. Why he did it, only bob knows. Reporter what did he think he would get out of it . He thought he would be able to show that hes not a monster, hes not a horrible person. Reporter bob watched the jinx at the same time as everybody else did. And according to jarecki, the filmmakers had given evidence to the authorities two years before the show aired. Which, to bobs attorney Dick Deguerin, meant the show was far from objective reporting. They edited probably 50 or more hours down into a few minutes. And i think the editing job was designed to make him look bad. Reporter but it was a simple comparison of handwriting samples that, on its own, seemed to condemn robert durst. It was episode five of the jinx series, in which a letter he admitted sending to susan berman was compared to the infamous cadaver note her presumed killer sent the cops. Soon after seeing that episode, bob packed up and left houston. But the cops were monitoring his cell phone and eventually tracked him to the Jw Marriott Hotel in new orleans. So, now, two fbi agents show up at the hotel and theyre talking to the clerk. Well, do you have anyone booked here under the name of Dorothy Ciner . No. They go through ten other aliases. No. No. No. Damn where is he . They turn around and theres bob walking in the lobby, headed for the elevators. Reporter later, they accompanied him to his room. And, ultimately, they turn up cash. A gun and some pot. Reporter so durst was booked for possession of a handgun and marijuana in louisiana and also arrested for the murder of susan berman in los angeles. And the very next day the final episode of the jinx aired, featuring the now infamous offcamera bathroom what was it . A confession . Killed them all, of course. Reporter what did you think of what you saw in that . Oh, god. I just looked at stewart, and he looked at me and we were speechless for a really long time. And then i burst into tears. Because it just, like, it was like a knife. Reporter after his arrest, a package arrived for him at that new orleans hotel. The police opened it. There were a pair of shoes in it and 117,000 in cash. Reporter hmmm. So, he was definitely getting ready reporter for something. A pair of shoes and money. Thats thats kind of what you need, isnt it . Thats right. Reporter and attorney deguerin stepped in again. This time, he acknowledged because of bobs trip to new orleans, getting him out of jail might not be so easy. I acknowledged early on, the chance of him making bail right now, the chances are slim and none, and slim just left town. Reporter if february 2016, pleaded not guilty to the gun and pot charges. And as for the susan berman case, attorney Dick Deguerin insists bob had nothing to do with her murder. But when deguerin does go to court he faces a tough deputy d. A. Named john lewin. You know, in texas we have a saying aint been a horse cant be rode, aint been a cowboy cant be throwed. Reporter but will the upcoming trials solve the mysteries of robert durst . Well, maybe not. Which is why were about to return to california and that place they call the lost coast. Coming up. We drove from Southern California up here. A missing teenager. I remember hanging flyers at the rest stops of my daughter, and just being like, this is not happening right now. How could this be . Karen, where are you . Investigators wonder is there a link .

Reporter of all the places robert durst wandered, this was not just a favorite, but now the setting of a lingering mystery, californias lost coast. In 1997, a pretty teenager named Karen Mitchell was helping out at her aunt annie caspars shoe store. I did not ever meet robert durst, but my manager, she said she remembered him because he just dressed as a woman. Reporter karen might well have met robert durst, said aunt annie. She often helped eurekas homeless population, people among whom bob was known to mingle. We cant know for sure. But we do know she was in bobs neighborhood more than once. Karen used to go to trinidad on the bus. I mean, they could have met. Its definitely a possibility. She liked unusual people. She liked to pick their brain and talk to them. Reporter the day she vanished, karen left the shoe store to walk to her job at a nearby Daycare Center where shed arranged to have annie pick her up after work. And as i came down, i had this weird feeling like something was off. Reporter it was. Karen never made it to work. Her mother, mary caspar, lived in los angeles. No forgetting what that phone call was like. We drove from Southern California up here. And i remember hanging flyers at the rest stops of my daughter, and just being like, this is not happening right now. How could this be . Karen, where are you . Reporter a massive search produced no sign of her. Though there was one curious lead, a witness who said he saw a young woman get into a car with an older man on this busy eureka road. The witness worked with a Police Artist to produce this. But nothing much came of it, at least not back then. Years passed. And then Matt Birkbeck, who authored a book on durst called a deadly secret, got a tip from some independent investigators also working the case, a possible connection. There were credit card records that placed durst in the eureka area the day that this girl disappeared. Reporter the transaction was just up the coast in trinidad, maybe 20 minutes or so by car from that spot where the witness saw a girl picked up on the road in eureka. And then, before the trial in galveston, birkbeck heard this. I have a really good source that was close to the defense team. And i was told that durst, he was extremely concerned about Karen Mitchell. And was so concerned that he thought he was going to get charged. Durst brought this up on his own for with his defense attorney . Yes. And Dick Deguerin apparently said to him, bobby, lets worry about one case at a time. Reporter not true, said Dick Deguerin. Ive never had any concern about it. Reporter did bob . No. Reporter but when durst was arrested in new orleans, the case was reborn. Andy mills was the police chief at the time. Robert durst is a person of interest in this case. Reporter hes definitely in the mix . He is in the mix. Someone that we will consider as part of our larger investigation. Reporter the chief was not alone. The fbi and the humboldt county d. A. Are investigating a possible bob durst connection, too. However, durst was not the only person of interest. There are five others. The evidence, the circumstantial evidence, is just not there at this point. Reporter that old composite sketch, for example, could this be robert durst . The chief isnt quite sure its particularly accurate. Looks very similar. Reporter were you impressed by the similarities . Im impressed by the similarities, but my questions are being able to recognize somebody in a very small space and window, and then being able to recount that in a description thats thats pretty precise. Reporter that sketch . Ridiculous, said dursts attorney, Dick Deguerin. I know bob pretty well. That doesnt look anything like him. It looks like mr. Potato head. Reporter so who was that witness of 18 years ago . Would he still remember . The cops hadnt spoken to him recently, so we found him riding his tractor in the green hills above eureka. His name is randy gomes, an army vet and a local carpenter. Did he remember . I looked right at him, because i was yelling at him. Reporter yelling at him, because that guy cut him off when he stopped his car to pick up a teenaged girl. You know, and i eyeballed him. Reporter yeah. All the way around as i was coming around the car. Reporter gomes insisted the girl got into the car willingly, as if she knew the man. So now 18 years later, we showed gomes his sketch and a picture of robert durst. What is your gut reaction when you see those two photographs together . I believe thats the man that i saw. Reporter so how sure are you you got it right . Im positive. In my heart, i know i have it right. Reporter and gomes is fairly certain, he said, the girl who got in the car looked like a photo the Police Showed him of Karen Mitchell. But it was her because she we made eye contact. Reporter but issues. There is no proof that it was Karen Mitchell who got into the car. And bob dursts eyes are not blue. And, said chief mills, gomes didnt come forward until months after the incident. What we dont want to do is just take something thats, you know, sensational and plug that person into the midst of an investigation that may or may not have anything to do with him. Reporter but the investigation continues. And some, like birkbeck, believe there may be more. Ive never said definitively that he was a serial killer. What i said was that theres so much out there about him, that clearly theres something going on here. And that Law Enforcement needs to look into it and, thankfully, they are doing it now. Reporter waste of time, said Dick Deguerin. Well, theres no evidence. And to think, you know, the they have to have a theory that hes some kind of serial killer. Hes not a serial killer. But the notion of robert durst as a serial killer has come up. You know, a guy who well, sells. It sells magazines. It sells books and causes people to turn on their tvs. Reporter a longmissing wife. A dismembered neighbor. A murdered friend. This is how robert durst is defined now. Where did it all go wrong . All that power, privilege, money. 60 years ago, a doctor warned that bobs hostility issues could lead to personality decomposition. Is that what happened . To his friends emily and stewart altman, bobby durst was a good person and loyal friend for more than 40 years. Stewart, an attorney who has represented bob in the past, has rejoined his legal team. And emily, painful as it is, worries that bobby durst may be the friend she never knew after all. Youre prepared . No. Reporter not prepared to deal with that . Hes my friend. I cant understand harming a human being, okay . Doesnt make sense to me. I dont know if i can forgive that and i wish i could, and im struggling with that. I dont know. Thats it. I dont know. Thats all for this edition of dateline. Im natalie morales. Thanks for watching. Im craig melvin. Im natalie morales. This is date line. He told me he loved me. I told him i loved him. He said he would be right back. I hear a comotion of some sort and then i remember hearing gunshots. Just lying there. It was bad. Its the website where lovers go to meet and cheat.
