Good evening again, im david muir. And im elizabeth vargas. Thank you for joining us on this saturday night. It was the explosive scandal. Justice delayed for so many years, as chandra levis parents waited for an arrest. And a conviction that would stick. But as we come on the air tonight, they are still waiting for justice. Just last week, the prime suspect was deported to his native el sad have a door for entering the u. S. Illegally. Heres deborah roberts. Reporter its not fords theater, or the watergate hotel. But this Simple Storage unit may soon claim its own place in the criminal history of washington, d. C. This is the place. Where did you put the recorder . I had the recorder right here behind that plastic bin. Reporter it was right here that this woman set up a bizarre amateur sting operation which would upend one of d. C. s most famous murder cases and, she says, endanger her own life. I honestly thought, hes going to kill me. Reporter were talking about the notorious chandra levy case. This case had everything. It had power. It had sex. It had the nations capital. It had a young woman on the rise. Reporter and now, because of this woman, the man once convicted of the murder, will walk free. Do you regret making those recordings . I had that recorder because my gut instinct told me something was really wrong, and something terrible could happen. Reporter tonight, youll hear her story. Hear from that suspected killer himself. Were on our way to meet the man many are convinced attacked and killed chandra levy. And Something Else youve never heard. I havent heard from you. Reporter actual voicemail recordings from the congressman at the center of chandras story. Its 11 45. Im sorry ive been tied up for the last few days, but you already know that. Reporter in fact, well begin right there, with what condit left on 24yearold levys home answering machine on a night in early may 2001. Maybe youre out of the country or something. Anyway, give me a call if you get this message. Bye. Reporter the democrat of Central California is wondering where chandra is. And hes not the only one. I called up and called up and then she didnt answer. Reporter bob levy, an oncologist, and wife susan are expecting their 24yearold daughter back home in modesto, california. She was shy. She really liked being at home. Reporter yet her daughter was ambitious, dreaming of a career in Law Enforcement. You sound like youre very content with the program and everything. Oh, yeah. Reporter shed even volunteered at her local Police Department before heading to the nations capital. She got the internship, the department of prisons there. And i think she was interested in going to the fbi. Reporter the fbi would be in chandras future, but not in the way she imagined. After nine months in d. C. , the internship is over. Chandra cancels her gym membership and emails her landlord that shes heading back to california. Then i called again, then on the weekend she didnt answer. Reporter five days pass with no word. Chandras anxious parents call police, who head to her apartment and make some noteworthy discoveries. It appeared to the police she was packed up, ready to go home. Reporter fbi special agent brad garrett, now an abc news consultant, worked the levy case for years. Her drivers license, her credit cards reporter her cell phone . And her cell phone were still in the apartment. Thats baffling to me and others because the whole idea is when youre going to leave, youre at least going to take an i. D. There were only two things missing, her keys and a ring. Reporter a gold ring with her initials, c. L. In diamonds, a College Graduation gift from her parents. What are you hearing from the police . They were sort of nonchalant, because what could they do . Reporter police do canvas the area, including nearby Rock Creek Park. And susan levy begins her own search, looking through her daughters cell phone bill. I saw this number that was being called many, many, many times, and i decided to call that number, and it turned out to be gary condit, and he answered the phone. Reporter what did you say . I was kind of surprised, and i said, do you know where my daughter is . I thought to myself, this is wrong. Come on in, make yourself comfortable. Give me ten minutes. Reporter but why, exactly, was the congressman, a ministers son and married father of two, calling a young intern to get together . Give me a call. Give me the rundown on kind of what your schedule is. Things are looking pretty good for me today anyway. Bye. Reporter condits always maintained he cooperated with police, and voluntarily came in for questioning. But former d. C. Chief of detectives, jack barrett, believes condit was being coy. He admitted to the detectives that first night that they were dating. We didnt know whether it was a friendly relationship, we didnt know if it was a sexual relationship. Reporter he didnt admit that he had a sexual relationship with her . He did not. Reporter word soon leaks that condit and levy did have something going on. Shed even dropped hints to her family. Listen to this home video. Chandra told us about her adventures in d. C. , the bureau of prisons and her congressman friend. Reporter and chandra had vaguely described a romance to her coworker sven jones. When she spoke of her relationship, she never offered a name. She just said powerful person, someone who she was in love with, someone who she could see making a life with. Reporter talk of a congressional sex scandal sets off a media firestorm. Police have questioned congressman gary condit, whos reportedly said levy spends some time in his washington, d. C. , area condo. In front of gary condits office, the whole street was blocked off with tv trucks, every day, out in front of the levys house, the same thing, with tv trucks, camera crews. Reporter were you wondering, or worrying, for a second, whether your father was somehow implicated in this . No, i knew he wasnt. I knew he had done nothing wrong, illegally wrong. When folks start calling my dad a murderer, its wrong. Reporter chad is condits eldest child, a top aide to the governor of california when the levy case broke. He hadnt hurt her, hadnt obstructed justice, told the Law Enforcement people from the start what the deal was. Reporter the levys arent buying it. And take their suspicions public. We would ask congressman condit and anybody else with information to please come forward. Please cooperate with the police. Do you know anything about where chandra levy is . From the very beginning, he was trying to protect his professional reputation. He was the one that created this problem for himself. We had no place to turn other than to try and focus on him. Congressman, why wont you take a polygraph . Reporter it becomes the summer of condit. American tvs saturated with daily images of the gaunt congressman, grinning through clenched teeth as he tries to maintain a facade of normalcy. I wish i would have gave him better advice. I mean, i wish somebody would have. You have a relationship, a friendship, that is hard to explain. Reporter yet, his dad will have some more explaining to do. Congressman, did you urge Anne Marie Smith to lie . Reporter people come forward, alleging condit had relationships with other women. He declines to discuss those allegations. We identified a number of women that were dating him while he was here in d. C. , and his family was back in california. Reporter the floodgates are open. Where is chandra . Reporter protests call for condits resignation. Resign resign reporter up next, while police arent turning up any breaks in the case, condit turns up on television, for a historically awkward interview on abc.

How you doing . Reporter its the summer of 2001, and gary condits role in the chandra levy case is blocking out the sun. The pressure is mounting on p on gary condit. The story was a congressman with an intern. It wasnt the story about this poor girl being missing. All these families being destroyed over this. Reporter posters of the young intern are plastered from the potomac to capitol hill. Her parents determined to keep their missing daughter in the public eye. Where is chandra . Reporter they make the rounds on television. We just want her back. Reporter but its not easy to maintain a brave face. Please help us. Help us find her reporter thats dr. Levy breaking down on abc sacramento affiliate kxtv. Police continue grilling the congressman, trying to tamp down the speculation. The congressman was not a suspect before the meeting. He was not a suspect during the meeting, and he is not a suspect since the meeting. Reporter yet the levys are convinced that condit not only committed adultery, but perhaps something much worse. I urge him if he does have any information please be man enough to step forward. Reporter hoping to change the narrative, condit agrees to a National Television interview with abcs connie chung. He felt as if i was interrogating him under a hot light. In many ways, i was. Reporter 24 Million People watch the interview. It went a lot like this. Congressman condit, do you know what happened to chandra levy . No, i do not. Did you have anything to do with her disappearance . No, i didnt. Did you kill chandra levy . I did not. We had a close relationship, i liked her very much. May i ask you, was it a sexual relationship . Well, connie, i have been married for 34 years and i have not been a perfect man, and ive made my share of mistakes. But out of respect for my family and out of a specific request from the levy family, i think its best that i not get into those details about chandra levy. Reporter was that respect for you . I laughed about it. Because i thought it was so false. Phony. Its just his way of weaseling out of it. It was preposterous. You just have to shake your head and say, why would he even agree to do the interview if hes not going to be forthcoming . Allnew dr. Phil. Reporter in november, condit gave an interview to dr. Phil, his first interview in 14 years. Came by your condo once . Well, maybe twice. Reporter he may have looked somewhat different, but he sounded pretty much the same. Why is it you will not answer publicly whether or not you had a sexual relationship with chandra levy . I havent, you know, answered that question publicly for 15 years and im not going to change my position or my view on that today. Reporter but if condit is reluctant to speak frankly, the forensic evidence speaks for itself. Chandra levys panties taken from her apartment shortly after her disappearance contained bodily fluids. Dna tests determined the fluid came from gary condit. Reporter think what you will of gary condit, theres no evidence he was involved in Chandra Levys disappearance. Most of us in the Police Department and the fbi agreed that he was not our suspect and that we needed to be looking elsewhere. The case of the missing washington intern. Reporter as the case continues to dominate the news, it seems nothing can trump the story of the missing intern and her friendly congressman. Until, of course, something does. And then september 11th happens. What happened to you and your investigation and your detectives . The Media Attention went away. We lost a big helping hand with the fbi, because they devotion of resources to terrorism, things changed dramatically. Reporter with the worlds attention diverted, the levys are left with little to go on. Because theres no body, you still hope shes alive somewhere, like with any missing person. Thats all you got is hope. Reporter as the case loses momentum gary condit lost his congressional seat. Reporter condit loses his bid for reelection, to nobodys surprise. Very difficult to win a race when youre being accused of murder. Its been a great opportunity to be in public service. Reporter weeks later, a striking coincidence. Awardwinning Washington Post reporter sari horwitz is revisiting the now cold case of the missing intern. I arranged a breakfast with a Police Official and during the breakfast, his pager just started going off. Reporter then, a timely break that a reporter can only dream of. And when he came back, he had this stunned look on his face. And he said, youre not going to believe this, but i just got a call, and they think they found Chandra Levys remains in Rock Creek Park. Reporter the remains lay in a remote section of washingtons largest park, five miles from chandras apartment. Finally, they discover her body in Rock Creek Park. Huge park. Huge park. Twice as big as central park in new york city. Reporter the gruesome discovery made by a park regular. U. S. Park. I was walking my dog and i came across a human skull. Reporter this is actual crime scene video. Those are chandras reebok sneakers, sony walkman and her jogging pants tied in knots, which will lead investigators to believe this was no accident. But no sighting of her gold ring. We cried. Yeah. Cried a lot. We screamed and cried. Yeah. You cant imagine, to have your child laying out there. It seemed so unfair. Reporter for detectives, the discovery brings relief. But also embarrassment. This is something that we all have to live with. There may have been dna evidence, all that was lost because of the fact that we were unable to locate her remains during the time that we were searching the park. Reporter the remains found 79 yards off a dirt path, down a sharply steep embankment. Police had searched 100 yards off all paved roads. Had they searched 100 yards off all foot trails, too, they may have found chandras body, dna intact, months earlier. Some people see that as evidence of ineptitude on the part of the police. Is that fair . Everybodys entitled to their opinion. Reporter critics say it wasnt to be the only police blunder. Days after levys disappearance, an untrained officer tried going through her computer, and accidentally corrupted the data. Which wouldve shown levy had researched Rock Creek Park. And on top of that, another oversight at her Apartment Building. What about the surveillance camera of her building . So many times people look to see who came and went in a building. Things like surveillance cameras unless you go and initially grab them or tell the management to hold them, they erase or disappear. And unfortunately thats what happened in this case. Reporter at least now the levys can have a memorial and lay their beloved daughter to rest. She was a quiet but very powerful force. Very smart and funny. I felt like she was going somewhere. It was just really disheartening. Reporter when we come back, police find more secrets in the park and set sights on a new man. Will there be justice for chandra . When we get two attacks on women by a guy with a knife in a short distance to where levys body was found, that stands out like a neon sign. Reporter and the voice of the witness who could both make and break the case. He told me he didnt know he killed her. It was an accident. Good morning um, i got something on this, but im not quite sure what it is. Its jelly. Definitely jelly. Its already coming out. Does tuesday work . Treat your clothes better with new tide pods plus downy. Cleans and conditions in one step. Its got to be tide. It shouldnt be whateverfleas and ticks. Home. No, no no no no.
