Tonight on 20/20 ` (CROWD) CHANTS: Where is Chandra? explosive new discoveries in one of America's most famous missing persons cases. A major development in one of the biggest murder cases of the last two decades. Chandra Levy, the Washington intern found dead in a park. This is where she either fell down, was pushed down or rolled down. How you doin'? Gary Condit, the politician under suspicion. How come she calls your office so often? But now, 15 years later,... Playing out like the plot of a crime drama. ...20/20 with the crime-scene video never seen before plus voicemails never heard. And a bombshell twist from a mysterious whistle-blower. Aren't you terrified hearing somebody describe how they killed people? Tonight on 20/20. Copyright Able 2016 Kia ora. I'm Carolyn Robinson. Welcome to 20/20. Tonight's story is one which made headlines around the globe. 24-year-old Chandra Levy was bright, ambitious and determined to carve out a career in the US capital. But her potential was never realised. Chandra Levy was brutally murdered in a Washington DC park, and the spotlight turned on Congressman Gary Condit, the married politician with whom she was apparently having an affair. Condit may have been guilty of adultery, but was he capable of murder? Tonight Deborah Roberts investigates one of the most famous murder cases in Washington DC's history. COMPELLING MUSIC It's not Ford's Theatre or the Watergate Hotel, but this simple storage unit may soon claim its own place in the criminal history of Washington DC. So, this is the place. Where did you put the recorder? I had the recorder right here, behind that plastic bin. It was right here that this woman, speaking on camera for the first time, set up a bizarre amateur sting operation which would upend one of DC's most famous murder cases and, she says, endanger her own life. I honestly thought, 'He's going to kill me.' We're talking about the notorious Chandra Levy case. This case had everything; it had power, it had sex, it had the nation's capital, it had a young woman on the rise. 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. Tonight, for the first time, you'll hear her story, hear from that suspected killer himself. We're on our way to meet the man many are convinced attacked and killed Chandra Levy. And something else you've never heard ` actual voicemail recordings from the congressman at the centre of Chandra's story. LOW MUSIC In fact, we'll begin right there, with what Condit left on 24-year-old's Levy's home answering machine on a night in early May 2001. The Democrat, of Central California, is wondering where Chandra is, and he's not the only one. I called up and called up, and then she didn't answer. Bob Levy, an oncologist, and wife Susan are expecting their 24-year-old daughter back home in Modesto, California. She was shy. She really liked being at home. Yet her daughter was ambitious, dreaming of a career in law enforcement. You sound like you're very content with the programme and everything. Oh yeah. She'd even volunteered at her local police department before heading to the nation's capital. Then she got the internship at the Department of Prisons there, and I think she was interested in going to the FBI. The FBI would be in Chandra's future, but not in the way she imagined. After nine months in DC, the internship is over. Chandra cancels her gym membership and emails her landlord that she's heading back to California. I called again, then on the weekend, and she didn't answer. Five days pass with no word. Chandra's 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. FBI special agent Brad Garrett, now an ABC News consultant, worked the Levy case for years. Her driver's licence, her credit cards` Her cell phone? ...and her cell phone were still in the apartment. That's baffling to me and others, because the whole idea is when you're going to leave, you're at least gonna take an ID. There were only two things missing ` her keys and a ring. A gold ring with her initials, CL, in diamonds ` a college graduation gift from her parents. What are you hearing from the police? Well, they were sort of nonchalant, because what can they do? INDISTINCT CONVERSATIONS Police do canvass the area, including nearby Rock Creek Park, and Susan Levy begins her own search, looking through her daughter's cell-phone bill. I saw this number that was being called many, many, many times. I decided to call that number, and it turned out to be Gary Condit's, and he answered the phone. And what did you say? And` And I was kinda surprised, and I said, 'Do you know where my daughter is?' And I thought to myself, 'This is wrong.' Come on in and make yourself home in my office, and I'll be back. Gimme 10 minutes. OK. I'll be right back. But why exactly was the congressman, a minister's son and married father of two, calling a young intern to get together? Condit's always maintained her cooperated with police and voluntarily came in for questioning. But former DC chief of detectives Jack Barrett believes Condit was being coy. He admitted to the detectives that first night that they were dating. We didn't know whether it was a friendly relationship. We didn't know if it was a sexual relationship. He didn't admit that he had a sexual relationship with her? He did not. He did not. Word soon leaks that Condit and Levy did have something going on. She'd even dropped hints to her family. Listen to this home video. BOB: Chandra told us about her adventures in DC ` the Bureau of Prisons and her congressman friend. And Chandra had vaguely described a romance to her coworker, Sven Jones. When she spoke of her relationship, um, 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. REPORTERS CLAMOUR Talk of a congressional sex scandal sets off a media firestorm. Police have questioned Congressman Gary Condit, who has reportedly said Levy spent some time in his Washington DC-area condo. In front of Gary Condit's office, the whole street was blocked off with TV trucks every day. Out in front of the Levys' house, the same thing ` TV trucks, camera crews. Were you wondering or worrying for a second whether your father was somehow implicated in this? No. I knew he wasn't. I knew he had done nothing wrong ` illegally wrong. When folks start calling my dad a murderer, it's wrong. Chad is Condit's eldest child, a top aide to the governor of California when the Levy case broke. He hadn't hurt her, hadn't obstructed justice, told the law enforcement people from the start what the deal was. The Levys aren't 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. REPORTER: Do you know anything about where Chandra Levy is? From the very beginning, he was trying to protect his professional reputation as a congressman. Scuse me. He was the one that created this problem for himself. We had no place to turn other than to try and focus on him. REPORTER: Congressman, now, why won't you take a polygraph? 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. REPORTER: Why do you feel the need to take a lie-detector test? Wish I would've gave him better advice. I mean, I wish somebody would've. You have a relationship, a friendship that is hard to explain. Yet his dad will have some more explaining to do. Congressman, did you urge Anne Marie Smith to lie? 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 DC and his family was back in California. The floodgates are open. (CROWD) CHANTS: Where is Chandra? Protests call for Condit's resignation. CROWD: Resign! Resign! TENSE MUSIC Up next ` while police aren't turning up any breaks in the case, Condit turns up on television for a historically awkward interview on ABC. Congressman Condit, do you know what happened to Chandra Levy? So does Gary Condit know what happened to her? We'll find out that and much more about this baffling case when 20/20 returns right after the break. DRAMATIC MUSIC Welcome back to 20/20 and tonight's story, Mystery in the Park. At the time, it was the biggest news story in America and made worldwide headlines. It was a case that had everything ` sex, political intrigue, mystery ` everything, it seems, except a suspect. But as Deborah Roberts continues the story, that is about to change. How you doin'? It's the summer of 2001, and Gary Condit's role in the Chandra Levy case is blocking out the sun. So, the pressure is mounting on Congressman Condit. The parents turn up the heat on Gary Condit. The story was a congressman with an intern. It wasn't the story about this poor girl being missing and all these families being destroyed over this. 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. (CROWD) CHANTS: Where is Chandra? They make the rounds on television. We just want her back. But it's not easy to maintain a brave face. Help us. (CRIES) Help us find her. That's Dr Levy breaking down on ABC Sacramento affiliate KXTV. (CRIES) 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. 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. Hoping to change the narrative, Condit agrees to a national television interview with ABC's Connie Chung. He felt as if I was interrogating him under a hot light. In many ways I was. 24 million people watched 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 didn't. 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've been married for 34 years, and, uh, I've not been a perfect man, and I've made my share of mistakes, but, um, out of respect for my family and out of a specific request from the Levy family, uh, I think it's best that I not get into those details, uh, about Chandra Levy. Was that respect for you? I laughed about it, cos I thought it was so false, phony. It's just his way of weaselling 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 he's not going to be forthcoming?' Just last week, Condit gave his first interview in 14 years to Dr Phil. Came by your condo once? Well, maybe twice. 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 haven't, you know, answered that question publicly for` for 15 years, and I'm not gonna change my, uh` my position or my view on that today. But if Condit is reluctant to speak frankly, the forensic evidence speaks for itself. Chandra Levy's panties, taken from her apartment shortly after her disappearance, contained bodily fluids. DNA tests determined the fluids came from Gary Condit. And yet, think what you will of Gary Condit, there's no evidence he was involved in Chandra Levy's disappearance. Most of us in the police department and the FBI agree that he was not our suspect and that we needed to be looking elsewhere. The case of the missing Washington intern. 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. STIRRING MUSIC And then September 11 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. With the world's attention diverted, the Levys were left with little to go on. Because there's no body, you still hope she's alive somewhere, like with any missing person. That's all you got is hope. As the case loses momentum,... Gary Condit lost his congressional seat. ...Condit loses his bid for re-election, to nobody's surprise. Very difficult to win a race when you're being accused of murder. It's been a great opportunity to be in public service. Weeks later, a striking coincidence. Award-winning 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. 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, 'You're not gonna believe this, but I just got a call, 'and they think they've found Chandra Levy's remains in Rock Creek Park.' The remains lay in a remote section of Washington's largest park, 5 miles from Chandra's apartment. Finally they discover her body in Rock Creek Park ` huge park. Huge park ` twice as big as Central Park in New York City. The gruesome discovery made by a park regular. This is actual crime-scene video, never before seen publicly. Those are Chandra's 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 can't imagine. To have your child laying out there, it seems so unfair. For detectives, the discovery brings relief but also embarrassment. This is something that we all have to live with is 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. The remains were found 79yd off a dirt path, down a sharply steep embankment. Police had searched 100yd off all paved roads. Had they searched 100yd off all foot trails too, they may have found Chandra's body, DNA intact, months earlier. Some people see that as evidence of ineptitude on the part of the police. Is that fair? Everybody's entitled to their opinion. Critics say it wasn't to be the only police blunder. Days after Levy's disappearance, an untrained officer tried going through her computer and accidentally corrupted the data, which would've 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 that's what happened in this case. 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. 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 Levy's body was found, that stands out like a neon sign. And for the first time, the voice of the witness who could both make and break the case. So even though Chandra Levy's body has been found, police are no closer to catching her killer. But when we come back, the investigation takes a sudden turn. DRAMATIC MUSIC Welcome back to 20/20 and the murder investigation that rocked the United States. Now, as Mystery in the Park continues, pressure from two reporters sees a suspect emerge. And as police struggle to find enough evidence to tie him to the murder, a witness is found. Sprawling Rock Creek Park in Washington DC. With its 2000 acres of lush trees, quiet streams and wildlife, a perfect place for a walk... or a crime. Look at how remote this is. It's quiet, there aren't any other witnesses, so this is an ideal spot for a predator to attack somebody. Yeah, this is right off the beaten path. Dr Kim Rossmo maps murderers. This is the apartment building near Dupont Circle where Chandra Levy lived. This is where Chandra Levy's remains were found. His title ` geographic profiler. His job ` analysing every location in a crime,... I think she followed the path here and then she was attacked, and her body was found here. ...decoding the patterns that can crack a case. We break a crime down to its constituent parts, so for a murder, we're gonna have an encounter ` the place where the offender first sees the victim. Then we're gonna have the point where he first attacks her. Then we have the actual murder scene itself. Then finally we have where the body gets disposed of. Russmo was brought into the Chandra Levy case by the DC Metro Police and the FBI after focus shifted away from Congressman Gary Condit. We made it pretty clear to the prosecutors that we didn't think that Condit had anything to do with it. Instead police gradually retrain their focus on this man, who'd been arrested for attacking two female joggers in the park just two months after Chandra's disappearance. Not enough attention was being paid to a suspect who was hiding in plain sight. Both attacks occurred in similar park locations. Same sort of path, same sort of slope ` though this was probably even steeper ` same sort of isolation. Both women fought off their assailant and survived. SIREN WAILS The first female jogger ` um, the one who was attacked about 700yd from where Levy's body was found ` said she saw Guandique in the Peirce Mill parking lot. If you look at where Chandra Levy lived, the logical route would've taken her right through the Peirce Mill parking lot. So who's the predator in the park? His name is Ingmar Guandique ` a 19-year-old undocumented construction worker from El Salvador. He had alcohol problems. He had cocaine problems. Sari Horwitz and her Washington Post colleague Scott Higham published an explosive series of articles questioning why the Metro PD hadn't pursued Guandique harder in the Levy case given his disturbing MO. He would sit at a park bench, and he saw a certain type of female that something inside of him would compel him to give chase. He would sprint up behind them, grab them around the neck and pull them off the trail. I'd seen an article in the Washington Post that talked about this guy called Guandique who attacked two women in the park. The microgeography was identical, so I was curious ` how`? how had they dismissed him? Why would somebody who attacked a woman and possibly even killed her come back to the same area and attack two more women right after that? Cos it worked for him. Guandique's hit with a 10-year sentence for the attacks, but now, after those scathing Washington Post articles, police look at the Levy case with fresh eyes, zeroing in on Guandique's activity around the time Chandra vanished. We know he didn't go to work on May the 1st. We know that he had marks on his face, um, following the disappearance of Levy that he gave inconsistent explanations for. But you can only solve a crime through a confession, physical evidence or a witness. But there's nothing to actually tie him to Chandra Levy? Unfortunately, uh, one of the best means of finding physical evidence from the body had been lost cos of its decomposition. But all is not lost. Coming up ` police find something ` make that someone ` who they say will finally connect Guandique to Chandra Levy. The arrestee is Ingmar Guandique. And still to come ` what role does this woman, an extra from House of Cards, and her secret seven-hour recording have to do with the case? I feel like I'm in House of Cards. 'HOUSE OF CARDS' THEME MUSIC And the house of cards that is the Chandra Levy investigation is about to come tumbling down when 20/20 continues after this break. DRAMATIC MUSIC Welcome back to 20/20 and tonight's story of one of the highest-profile murder mysteries in the US this century. Now, as Mystery in the Park continues, the trial of the man accused of Chandra Levy's murder turns into a drama-packed affair. Congressman Gary Condit is dragged back into the case, but a Californian gangster is the key player, and, as Deborah Roberts continues the story, there's about to be a major twist. It's been nearly a decade since Chandra Levy's disappearance, and now prosecutors finally bring murder charges against Ingmar Guandique and take him to trial. The Chandra Levy trial is set to begin today. A case that once riveted the nation. What was it like for you being at that trial? It wasn't easy. Cameras aren't allowed in the courtroom, but the emotional testimony from two female joggers who survived Guandique's attacks take the gallery's breath away. It's almost like Chandra is testifying through these women on the witness stand. Gary Condit has been diligently avoiding the spotlight but now finds himself right back in the middle of it. REPORTER: Mr Condit, anything you wanna say? Called to testify, he heads to court with a media circus in tow. Think he was kinda the elephant in the room, and they needed to demystify him. Former US attorney Tim Heaphy prosecuted cases in the DC office. It would've been too easy, if he were a silent presence, for the defence to suggest directly or subtly that he was the real culprit. A Condit sighting always makes headlines, but now prosecutors are hanging their case on a secret weapon. REPORTER: Today one of the prosecution's star witnesses. Meet Armando Morales, a California gangster with a record and tattoo to prove it. That paw print marks him as a member of the Fresno Bulldogs, a gang notorious enough to merit a documentary on the History Channel. Here's Morales' cameo. A Bulldog named Armando 'Mousey' Morales. Back in 2006, Morales and Guandique were sharing a federal prison cell for separate crimes. Now on the stand, Morales makes a stunning allegation ` Guandique made a detailed confession to the Levy murder. Juror Sharae Bacon ` His testimony was convincing. He knew certain things. After Morales' testimony, Guandique is found guilty and sentenced to 60 years in prison. REPORTER: A jury convicted Ingmar Guandique on two counts of first degree murder. The results of the verdict may be guilty, but I have a lifetime sentence of a lost lamb missing from our family tree. One of the country's longest ongoing murder mysteries is finally over. Or is it? The conviction starts to wobble two years later when the defence discovers that the snitch, Morales, concealed a crucial fact from the jury ` he'd had a history of working with law enforcement. Knowing those prosecutors, my guess is they had no idea until after the fact about Mr Morales' prior cooperation. Maybe they should have. Honest mistake or not, it's a big enough deal to make some very big news. REPORTER: The accused killer is getting a new trial. What happened for you when you heard that Guandique was going to get a new trial? There was a part of me says, 'Well, maybe Mr Condit's gonna be asked 'to come back and talk a little bit more in depth.' Susan's instincts are spot on. A major development in one of the biggest murder cases of the last two decades. The defence is pointing the finger at California congressman... Guandique's attorneys allude to a defence straight from 50 Shades of Grey. SNAP! They wanted to develop information about other relationships he had, uh, that may have involved rough sex play. It looks like Condit's sex life could be on trial. But wait. OK. Out of nowhere, this woman is about to crash into the case. Things will never be the same. A 15-year-old murder case is turned on its head because of you. Did you ever expect that? No, absolutely not. She's reluctant to talk to us, saying she's in danger and keeps her whereabouts secret. You don't want us to say where you are? (SIGHS) Um, I feel unsafe. Her name is Babs Proller ` a small-time actress originally from Germany ` an extra, coincidentally, in the smash political drama House of Cards. We overcame those tensions. So how exactly did she land a role in a famous DC murder case? I mean, sometimes real life, I think, can be... ...stranger than fiction. ...stranger than fiction, absolutely. Her strange tale begins this past July in Annapolis, Maryland. Babs is going through rough times and staying for a while at this Country Inn & Suites. During her stay, she crosses paths with a mysterious middle-aged man who calls himself Phoenix. He was very kind. He was very friendly. He seemed like a very personal, nice... guy. Was there a spark going on here? No, no, no, no, there was no spark. But they grow closer, and a friendship ensues. Phoenix even babysits Babs' golden retriever, Buddy, while she's out of town. That him with Buddy, and Buddy actually had the paw up there on him. But don't let those sweet selfies fool you. Phoenix has a paw of his own ` that tattoo marking him as a former gangster from the Fresno Bulldogs. He is, in fact, the same snitch who testified so convincingly at the Chandra Levy trial, Armando Morales. His face changed completely. It went from this gentle, kind, caring guy into a look that almost scared me a little. Trusting his new friend, Morales reveals he's just done 20 years in prison. I said, '20 years? You must have almost killed someone to be in for 20 years.' And his answer was, 'I wish it would've only been one person.' So what's he doing here? Morales explains he's the key witness in the upcoming retrial of Ingmar Guandique. While preparing to testify, the government has put him up in the hotel with a cell phone, a room key and some cash and strict orders not to blow his cover. What did you think? I was intrigued of his involvement, what he knew. She's intrigued enough to continue the odd friendship but also scared that the criminal could hurt her or those close to her, so she makes a fateful decision. Babs says that for her own protection, she begins recording her conversations with Morales in the hotel, in the car, even in this storage locker, where he's helping her organise her things. This is where you recorded it all, mostly? I did. Next ` those secret recordings that will rock the Levy case and get a convicted killer out of prison. What started as a circus ended as a circus. And that circus is set to continue when we come back after the break with more from the unlikely private investigator Babs Proller. That's when 20/20 continues. DRAMATIC MUSIC Welcome back to 20/20 and the disappearance of Chandra Levy, the 24-year-old brutally murdered in a Washington park. As Deborah Roberts continues Mystery in the Park, there's more to come from Babs Proller, as her secret recordings are set to turn this case on its head. SUSPENSEFUL MUSIC A row of storage units near Annapolis, Maryland ` isolated, a little spooky, maybe not the first place you'd pick to secretly record a career criminal. But, then again, you're not Babs Proller. So, this is the storage facility, and this is the unit that I worked with Armando. And you had your recorder on you when you were in here? I did. I put it, actually, right here on the shelf. Do you see yourself as some kind of an investigator? Is that what you're out to do? Are you out to get the attention? No, I didn't want to have my name, really, involved. It was supposed to be exposed at all. I only started taping because I truly was afraid. 20/20 has obtained seven hours of conversations between Babs and her new friend, Armando Morales,... ARMANDO: I got a 22-year sentence for gang racketeering. ...the prison snitch so crucial to the Chandra Levy investigation. The tape seems to reveal that the ex-con, Armando Morales, hasn't forgotten his gangster past. And listen to how he brags about cooperating with law enforcement to put Ingmar Guandique away for the Levy murder. I think he was trying to impress an attractive woman. He had been in prison for 20 years. He's about to testify in one of the biggest trials in the United States, and to be talking to a stranger, it was a rookie move for a lifelong criminal. When conversation turns to the Levy case, Morales tells Babs what he told the court ` that Guandique told him the crime was a robbery gone wrong. Curious Babs starts probing, telling Morales she's not convinced the right guy is behind bars. Any time I ask a really detailed question, he would go into, 'Don't go there.' She says all those evasions make the whole account seem fishy. To me, it didn't make sense. I ended up feeling like, 'You made this up.' Why would he lie? Why`? What was in it for him? He said, uh, 'I wanted protective custody. 'I no longer wanted to be afraid, because I was always afraid.' Which is exactly what Guandique's defence attorneys argued in a 114-page filing. Plus, Proller says, Morales may have hoped the Feds might help him dodge a murder rap of his own back in California. He said in Fresno he was involved in a gang-related, um, murder that they're trying to pin on him but that's being handled. Aren't you terrified hearing somebody describe how they killed people? Absolutely. Uh, scared out of my mind. I would be. Morales might be protected by the government, and Proller might be in danger, but for whatever reason, she keeps pressing record and keeps pressing Morales. Finally, she claims, her persistence pays off. Morales cracks, admitting he fabricated Guandique's confession. And then he says, 'You know what? The prosecutors wanted me to lie. 'They knew they had the right guy. They just needed somebody to say it.' He said that to you? Yes. > And you have that on a recording? Mm-hm. Of course, we wanted to hear that part of the recording, but ` get this ` after repeatedly assuring us it exists, Proller has not produced it. Prosecutors have categorically denied what they call 'baseless allegations'. < Some people would say you have credibility issues. Make that legal issues too. We've discovered Proller has a chequered past. The suggestion is that you've had aliases, that you've had, sort of, a sketchy past yourself. No, no. I was married twice, and I had my name officially changed after the divorce. 'There's also an accusation of theft.' What about the theft? Were you charged? I was charged. Enough to earn her three years' probation. Some would say you're a scam artist. True? I've never taken anything from anybody. I have not take money. What am I trying to scam out of this? OK, maybe it was just a passion for justice that then drives Proller to reach out to Chandra Levy's mom, Susan. What did she say? 'Morales lied about Guandique's confession.' And what are you making of this? I thought, 'Oh my God, this is so weird. Why don't you send a tape for both the prosecutor defence team?' 'Send it to them.' The prosecutors met with me first. So they couldn't have liked this. No. No. But if prosecutors listened to the same recordings we did, they didn't hear Morales confessing; they heard him sticking to his original story. He didn't recant his testimony. In fact, he doubled down on his testimony. Morales' attorney tells 20/20 he never told Babs he made up the confession. Despite all that, this past July, the bombshell detonates. There is a stunning turn tonight. Prosecutors suddenly dropping a murder charge... The US Attorney's Office drops the case, releasing a tersely worded statement. The multimillion-dollar question ` why would they drop the Chandra Levy case? Clearly something occurred which probably eliminated Morales as a witness. On those tapes, he brags a lot about his thug life and his life as a criminal. It's a defence attorney's dream come true. It would be a subject of cross-examination, and the calculus could have been there's just too much baggage for this witness ` too many things that he has said and done. Whatever Proller's true intentions, the Chandra Levy case is now in shambles. It fell apart because this` this woman tampered with the witness. Why did she do that? What was her motive? I felt guilty. I felt really bad about what happened. Why? Oh, I thought, 'Well, maybe I should not have called this number.' The Levys now have the rest of their lives to ponder the 'what if's, and Proller says she's worried Morales will come after her for revenge. His current whereabouts is unknown. My life has been affected negatively. I'm moving from hotel to hotel right now. I'm afraid. Why did you decide to talk with us? I believe that the truth needs to come out. I think somebody out there knows something. I've tried to be brave through all of that. Just weeks ago, during a visit to Rock Creek Park, where Chandra Levy's remains were discovered,... Hello? ...20/20 producers got an unusual phone call. AUTOMATED VOICE: Un residente en... WOMAN: ...Farmville Detention Center. Si, hola, Ingmar. INGMAR: Si. The undocumented immigrant, recently freed from a 60-year sentence for the murder of Chandra Levy, sits in an immigration detention facility, awaiting deportation, and now has agreed to speak only with 20/20. Hello? Ingmar? Si. Immigration and customs enforcement has a strict no-camera policy in their facility, so we give Guandique a call. Have you ever harmed a woman? Have you ever shoved or hit a woman? (SPEAKS SPANISH) This could be your last chance to set the record straight. Did you attack Chandra Levy? Did you confess to Morales? He sounds a bit rehearsed, so we decide to fly down to the highly secure detention facility in Farmville, Virginia,.. MAN SPEAKS INDISTINCTLY ...to look Guandique in the eye. We're about to sit down with Guandique. I'm gonna show him a picture of Levy and ask him, face to face, if he killed her. Inside, he continues to maintain his innocence, saying he's found salvation for his previous crimes. Guandique seemed anxious to talk to us. He was filled with lots of details about why he's innocent, and, of course, he denied that he ever touched or killed Chandra Levy. 15 years after Chandra Levy first went missing, here's where things stand today. The prime suspect, Ingmar Guandique, wants to stay permanently in the US. It's unlikely that will happen. He's clearly got aggravated felonies, which is grounds for deportation. Disgraced congressman Gary Condit is out of politics and, for the most part, out of the public eye, but there he was last week, plugging his new book on Dr Phil. I'm not the victim in this. The real victim in this is Chandra and her family. The reporters Sari Horwitz and Scott Higham wrote a book about the tangled investigation called Finding Chandra. Both insist the misguided focus on Condit is the reason Levy's killer is not behind bars. From the beginning to the end, terrible mistakes by police and prosecutors, and in the end, no justice. The investigation is described to 20/20 as 'open but not active'. The last hope could hang on that precious golden clue. Her ring is still missing. Guandique may have sold it or gave it to somebody. You know, hopefully they'll watch this programme and, um, let the police know. Whoever has that ring knows something about her disappearance and murder. Finally, Chandra's parents, deprived of their daughter, deprived of justice, find some comfort in spiritual hopes. READS: 'Happy birthday. Love, Uncle Paul and Linda.' Aw. Are you preparing for the possibility that you may never know what happened to your daughter? One day I will be with our daughter, and whether we'll get an answer from God or not, I don't know. We'll find out then. And then maybe what Chan would've said is, 'What difference does it all make?' (LAUGHS) (LAUGHS) Ingmar Guandique is fighting extradition back to El Salvador. Gary Condit has never admitted an affair, and he remains married after 50 years. Chandra Levy would now be 40 years old, and her family, well, they are back to square one. That's our show for tonight. Thank you for joining us. Kia ora. Nga mihi.
