good evening. thank you for joining us. tonight a multi-millionaire has been charged with murder. robert durst made his money the old-fashioned way, he inefforted it. now he's behind bars. many saying it was the new hbo documentary that helped land him there with what sounds like a

confession recorded in the strangest of places. >> reporter: robert durst's long and bizarre walk to justice resumed today outside a new orleans court. some of the most potentially damning evidence against him this time his own words. >> did not tell the whole truth, nobody tells the whole truth. >> reporter: words parcelled out during the six-part hbo judgment tear "the jinx" which chronicles his 30-year legal odyssey. from heir to a billion-dollar new york real estate fortune to a suspect in not one but three killings. today's court appearance connected to number connected to murder number two. his apparent undoing, a shocking revelation in last night's final episode. >> i want to ask you about the note -- >> reporter: confronted with new evidence by the filmmaker. what may be the most incriminating moment was still to come. >> i am going to go use the restroom. >> reporter: when a strip to the bathroom, durst's microphone

still working, he made what appears to be a muttered confession. >> what the hell did i do? killed them all, of course. >> reporter: gma reacting to the find. >> it was so chilling to hear it. it was disturbing to hear it. makes you very uncomfortable to hear it. >> reporter: an explosive turn in a dark and twisted tale sparked the public's imagination since 1982 ever since his first wife kathleen, a medical student, mysteriously vanished. he was never charged in her disappearance. but allegations of domestic abuse, fueled rumors he was involved. friends say kathleen was afraid of her husband. >> oftentimes she would ask me to stay with her at her apartment because she was in fear. she didn't know what was going to happen next. >> reporter: but she never filed a complaint against him. >> did you have anything to do with the death of your wife? >> i don't know that she's dead. >> do you think that it's possible she's alive now? >> it's possible. not likely.

>> reporter: the case went cold. but in 2000, new york state authorities renewed their focus on durst in connection with kathleen's disappearance. >> i began the investigation and started looking to talk to all of the people who knew robert durst at the time in 1982 when she went missing. >> reporter: and then a second mystery. this time his good friend and spokesperson susan berman found murdered in her california home. >> i felt terrible for susan. was astonished they were putting all this together that i did it or i caused it to be done. >> reporter: berman scheduled to tell sport utah authority what does she knew about the case. >> durst was sending susan berman money $50,000. why would he send her that much money? at or about the time that we're looking to talk to her? kite to be shut her up? could it be to convince her not to say the truth? >> reporter: once again, durst evaded formal charges. in an attempt to escape the negative attention, durst fled

to texas disguising himself as a woman. then a year later another gruesome discovery. a fisherman in galveston bay finds a garbage bag washed up onshore. >> i was shocked to see that there was a torso. no head, no legs no arms. >> reporter: later, the corpse's arms and legs are found. the head still missing. the victim 71-year-old morris black, robert durst's neighbor. durst was arrested but not knowing he had access to millions, authorities set his bail at $250,000. he was quickly wired the money. then in another questionable move he fled. >> good-bye $250,000. good-bye jail. i'm out. >> reporter: over a month later, he was captured in a small pennsylvania town. >> where he was caught stealing a hoagie sandwich, a $7 sandwich. >> reporter: at his murder trial durst admitted to killing morris black and dismembering the body but claimed it was self-defense. >> he admitted to a killing in texas.

he didn't admit to a murder in texas. >> we the jury find the defendant not guilty. >> reporter: he was acquitted of murder. sentenced to five years in jail for evidence tampering and bond jumping. durst was paroled in 2005. he lived mostly out of the public eye. >> marry me? >> reporter: until 2010. with the feature film "all the good things" starring ryan gosling as a fictionalized version of robert durst. >> i said to my partner, i would like to make a movie that robert durst himself could sit and watch and have an emotional reaction to it. >> reporter: durst did watch. and contacted jarecki with an irresistible proposition, despite his lawyer's advice. >> our interview is a big risk for you. >> reporter: in the process of investigating the documentary, the director and his team obtained a blockbuster piece of evidence from susan berman's stepson, who was friendly with burst at the time. >> it was clear enough that i might be dancing with the devil. >> reporter: a letter he says was sent from durst to berman

several months before her murder. the handwriting appears eerily similar to an anonymous note sent to police alerting them to search for bearrman's ka nufr a letter authorities say only the killer could have written. >> what does that say to you? >> the writing looks similar. the spelling is the same. i can see the conclusion the cops would draw. or the writing exemplar peon. that they were both written by the same person. >> so i guess the question is did you write the kacadaver note? >> no i didn't write the cadaver note. >> reporter: then the shocking solitary confession. >> there it is. you're caught. >> reporter: you have the bathroom confession, the writing samples, which is more significant? >> the confession is splashier but i think the writing the letter, may be a stroerng piece of evidence. there's been talk of the

documentarymakers. that it seems like they had evidence that they didn't provide to police early enough. andrew jirecki and his team say that they gave the police this evidence months ago. it has to make you ask, then how could they have not arrested him earlier? >> reporter: the lapd released a statement saying that based on the evidence investigators had, the arrest was made. the decision was not based on the hbo series. and they said an anonymous tip from a viewer led them to this new orleans hotel where durst was holed up under an alias. his defense team who appeared in court today, aren't buying the timing was just a coincidence. >> it's pretty slick. probably very misleading too. >> any deals over the time of the arrest? >> no, of course not. a, we could have that kind of power. we're not in charge of the arrest timing. we had no idea of the arrest

timing. >> the defense is going to try to put andrew jirecki, his team and lapd on trial. they're going to say they were working together to try to bring down robert durst. >> reporter: in effort to discredit the evidence that's already brought him down in the court of public opinion. next front-runner rumor takes us behind the scenes of "dancing with the stars." and reveals why her parents were cheering together from the audience. plus controversial opinions up their fashionable sleeves. how sir elton john is firing back against the designers tonight. s a punch, right? oh yeah. pinch me. okay... and on passat models you can get a $1,000 volkswagen credit bonus. one more time. pinch me. it's not a dream. it's the volkswagen stop dreaming, start driving event. stop dreaming, do it again. and test-drive one today. hurry in and you can get 0% apr

tonight, "dancing with the stars" welcomed a whole new cast for the start of the season. one person who's prepared contestant ruler willis. the rising star is shining all on her own explaining how mom and dad support her together. here's my "nightline" coanchor juju chang. ♪ let me give you my life ♪

>> reporter: hollywood royalty in the audience tonight for "dancing with the stars." bruce willis and demi moo cheering on their daughter actress rumer willis who took the stage last but set the stage as the one to beat earning the night's top score. >> 32 out of 40! >> reporter: the amateurs include the under-breaking football star michael sam and charlotte mckinney, the buxom blond bombshell known for this year's hottest super bowl ad. >> introducing the all-natural burger. >> reporter: who did the jive tonight. we went behind the signs with rumer willis as she and partner val shmirkovsky rehearsed. >> i feel really yateful i have a family that's supportive of the crazy and wacky things i decide to do. >> reporter: willis' family tight, a bond that stood the test of time. >> your parents' divorce was so

high profile, i think a lot of people of your age watched that because your parents were parenting as divorced people. >> yeah. i think that they really set a trend of people who had split up being able to really still have a family dynamic. i have so much gratitude that that's the way that i was raised so i didn't have to split holidays and birthdays, that they made an effort to keep a family unit. >> what, if anything, scares outpost about this? >> her parents. you know, all jokes aside, every season is -- i don't know, why but for me the family of my partner is really important. their opinion is really important. >> reporter: we caught up with other contestants like farmer turned bachelor chris going for a spin on the dance floor with the new whitney in his life. not his fiance whitney bischoff but reigning champ whitney carson. >> my first concern was that she was comfortable with it. because it is you know a different deal. where i'm going to spend a lot

of time with whitney and she's going to have to watch me dancing with another woman. and she handled it really well. she wanted me to do it. it's going to be fun for both of us. >> reporter: other dancers were making fans proud too. you'd never guess from her dance tonight suzanne somer is now 68. or that r&b legend patti labelle is 70. but this season also features the youngest dancer ever. 14-year-old willow shield who plays katniss' younger sister primrose in "the hunger games." her tender age sparking controversy. how young is too young to shake booty? >> some people think you're too young. >> yeah, i wanted to do it so that i could show other girls my age that they could do things that scare them or they could do something that they've never done before. i want it to kind of be inspirational for young girls too. >> reporter: her pro partner in crime, mark, scoffs at the idea anyone would find it objectable. quite the contrary. >> in our real world, in the

competitive world, we have age divisions. people as young as 5 up to 11 will compete. that's the juvenile division. >> in your mind there is no too young to ballroom dance? >> absolutely no too young, no too old. not one part was deemed inappropriate or racy or weird. that's not my thing. anyone that would see what we're doing and think that? that's weird. >> what about the costuming? it can get risque and you're only 14. >> we're definitely keeping the costuming age-appropriate. >> reporter: performing under pressure is something michael sam knows well. last year becoming the first openly gay player drafted into >> i am openly gay. there are a lot of openly gay people in the entertainment business but i'm a professional athlete, trying to be in the nfl. >> reporter: tonight cutting up the dance floor with the cha cha. while simultaneously training to gain a spot on an nfl team. >> i was invited to the nfl combine. actually i'll be next sunday,

i'll be participating in that. that monday i'll be dancing the second song. >> reporter: rumer willis has acted on "pretty little liars," and "90210." but her real passion is in the theater. she says live performance is her new jam. >> what do you like about theeter? why that direction? >> it's just fun. i think the same thing with dancing or anything live that when you get the audience's energy, i think it really starts to fuel what you're doing. >> reporter: growing up under the media glare has prepared her for what could be a life-changing moment. >> i noticed right away even just my competence when i walked into a room. i've gotten used to hiding. your life is on public view. i think -- i didn't realize it as much before how much you try, or i've tried to kind of hide. i almost do that with body language. i notice it in pictures my head is down. the worst mistake you can make in the public eye is try and hide and not be yourself. >> reporter: now stepping into

the spotlight on her own terms. >> do you feel like this is a moment for you to step out of their shadow? or you love having them around? >> i don't necessarily feel like i've been in their shadow. i've not -- my goal is to not be them. i'm not trying to be my parents. i'm just trying to be myself. for me it's more just about having an opportunity to show who i am regardless of where i've come from or who my parents are. >> reporter: for "nightline," i'm juju chang in hollywood. tonight it looks like our girl rumer is the front-runner. who are you pulling for this season? head to our "nightline" facebook page and let us know who's got your support. next why is la toya beckham taking a stand against dole dha and gabbana? ruffling feathers in hollywood tonight. i'm louis, and i quit smoking with

chantix. i told myself for so long that i needed to quit smoking. i would quit then i'd go right back to it. chantix absolutely helped me quit smoking. along with support, chantix (varenicline) is proven to help people quit smoking. chantix helped reduce my urge to smoke. some people had changes in behavior, thinking or mood hostility, agitation, depressed mood and suicidal thoughts or actions while taking or after stopping chantix. some people had seizures while taking chantix. if you have any of these stop chantix and call your doctor right away. tell your doctor about any history of mental health problems, which could get worse while taking chantix or history of seizures. don't take chantix if you've had a serious allergic or skin reaction to it. if you develop these stop chantix and see your doctor right away as some can be life-threatening. tell your doctor if you have a history of heart or blood vessel problems or develop new or worse symptoms. get medical help right away if you have symptoms of a heart attack or stroke. decrease alcohol use while taking chantix. use caution when driving or operating machinery. common side effects include nausea trouble sleeping and unusual dreams. i'm not worried about smoking my next cigarette. to me that feels great. ask your doctor if chantix is right for you.
