narrator: back to our story. an alleged killer is behind bars, but a mystery remains. abe said he felt like his son was targeted, right? correct. that it was a hit job? correct. narrator: the fbi is trying to prove it's adam's estranged wife who ordered the hit. she's one of the very few people that i would say, are very evil and conniving.

she was crafting a new life for herself. narrator: adam's father had been fighting to get justice. it was about to get much harder. the fbi did an incredible job, but they don't have jurisdiction in italy. narrator: so abe decides to take matters into his own hands. it wasn't about retribution. it was about justice. abe didn't stop. narrator: some of the biggest discoveries are still to come. she used her sexuality. it's just a crazy twist after a crazy twist. narrator: by the spring of 2008, 2 and 1/2 years after adam's death. the fbi had tracked down the man believed to be his real killer, alex "el loco" pabón. pabón not only confessed, but also said that adam's wife, urea, had offered him $3 million to kill her husband.

but urea wasn't the only person pabón implicated in the conspiracy, according to fbi special agent, devin kowalski. he had a series of meetings with urea, her sister, marcia, her sister's then boyfriend, josé ferrer, in the lead up to the murder. narrator: urea, her sister, her sister's boyfriend all allegedly in on the plot to kill adam. pabón, an admitted drug dealer, said he often did business at pink skirt, urea's bar, where marcia and pabón both worked. pabón said it was there, that the trio first approached him. they had met before to discuss beating adam up. narrator: throughout the investigation, the fbi worked with the united states attorney's office in san juan. josé ruiz-santiago and jennifer hernandez vega are assistant us attorneys there. two days before the murder, they decide that adam has to be killed. narrator: pabón also gave investigators his version

of how the murder went down. he articulated being called on the morning of the crime, september 22, 2005, and kind of, being hastily instructed to find some type of a weapon in order to-- a knife-- to be able to commit the attack. he detailed the choreography that existed between him and josé on the day of the murder to tell him to be in a certain location and that-- to expect that urea and adam will be walking up in this general direction. narrator: pabón said he was told to hurt urea just enough during the attack, so it wouldn't appear he had targeted adam. investigators believed urea set the plan in motion by insisting adam have dinner with her that night. she makes multiple phone calls to adam's work in attempt to speak with him to arrange a dinner later that evening. narrator: adam agreed, and remember, since he thought they would be finalizing their divorce terms, made the fateful decision to give his bodyguard, carlos, the night off. carlos believes urea knew adam would come

alone if she played nice. so urea picked adam up at his office, drove them into old san juan. pabón told investigators what happened next. he receives a call from josé ferrer sosa indicating that they were ready or it was about to happen. at that time, urea is having dinner at the dragonfly. and that is when the plan goes into action. narrator: the security footage from that night captured adam walking with urea, unaware these were the last few moments of his life. pabón told investigators it was urea who took adam from the restaurant to pink skirt after they had dinner, knowing pabón was waiting nearby. it was urea who gave pabón the signal to start following them. and it was urea who led adam up the cobblestone streets to his death at the hands of pabón . he follows them up the street at all times seeing that urea was with adam at the time.

then he approaches him and attacks adam, narrator: witnesses said urea just stood there watching as adam was killed. she didn't call for help. she didn't try to save her husband. she didn't even run. those witnesses also reported a brief conversation between urea and the attacker before he punched her to the ground. it wasn't just urea's behavior that raised a red flag. so did her injuries from that night. adam had been brutally murdered with the knife and cobblestones and bled to death on the street. and she had a little nick on her head, and forgot the scream, and forgot to run. narrator: and there was something else that the agents found incriminating, the couple's prenuptial agreement. the terms of her prenuptial agreement made it significantly more lucrative if he died versus a divorce.

roughly, she would receive $3,500 a month for three years if they divorced. if he died, she was going to take home eight or $24 million. it was a math equation. narrator: it was motive. eight months after abe walked into the fbi's offices and asked them to look into his son's murder, the fbi felt confident there was enough evidence against urea to arrest her. and so on june 4, 2008, urea was indicted on charges of hiring a hitman to kill adam. jonathan roman was released from prison and exonerated. but any vindication adam's family and friends felt was short lived because urea was not behind bars. in fact, she wasn't even in puerto rico. i got to give her credit. she was a very smart woman, very conniving. narrator: coming up--

--she was crafting a new life for herself. narrator: -- urea has a new country and a new family, giving the fbi a new problem. she had children there. it's our belief as a means to justify her citizenship in order to stay there. narrator: when "dateline" continues. ooo! our car's value went up! maybe we should track all our cars' value on carvana? we need more trackers! oh! i'm getting a value update! do you see which one is going off? how's it trackin'? some dips, some rises. now what?

culminating with the indictment of his wife, urea. but urea was not in jail because by the summer of 2008, she had long since left rico. interviewer: and f was urea at this point? so urea had absconded to florence, italy in 2006. and so i guess, she figured, i don't want to be in puerto rico. i don't want anything to do with this, so let me get away. narrator: nine months after adam's death, urea had arrived in florence on a student visa, supposedly to study filmmaking. she made trips back to puerto rico. but by the time of her indictment in 2008, it was clear she saw her move to italy as permanent. and it's not as if this lady didn't know what she had done. she knew. but she was crafting a new life for herself. narrator: but she was doing so without any of the money from the prenuptial agreement. abe, as executor of adam's estate, had refused to pay urea until all

investigations into his son's death had been concluded. in italy, urea, now a brunette, was going by the name, beatrice domenici, bibi for short. she started a relationship with the local man. and in august 2008, she gave birth to twin girls. i met her at work. first, she was my colleague. then we became friends. narrator: iwona alma met urea when they both worked at a tourism office in florence. she was very professional. she spoke at least three foreign languages, english, spanish. and she was speaking quite good italian. she was very kind, very friendly, very gentle. that is the church of santa croce. narrator: and iwona says urea was devoted to her children. bibi was a good mother. she was very sweet with them. she was very patient as a mother should be.

narrator: not long after the twins were born, urea agreed to an interview with journalist, josé sanchez fournier, who traveled to florence to meet her. she told us the reason she went to florence was because she always wanted to be a tour guide, and she loved florence. narrator: urea maintained her innocence, but josé was skeptical. we was a long interview. we spent a couple of hours with her. but she seemed oblivious to undeniable facts of the case. narrator: like for instance, the circumstances surrounding adam's murder. urea maintained the attack was a robbery, not a hit. by then, it was obvious that this was not a straight mugging. but she always said, no, for me, this was a robbery. narrator: urea denied knowing the killer, alex "el loco"

pabón and claimed she sought the fbi's help shortly after adam was killed. the interview made for a sensational story back in puerto rico. it caused quite a stir because the article showed how urea was openly renouncing reality, you could say. she was holding on to her side of the story. why couldn't you guys just go to italy, give in the information, and arrest urea at that point? the fbi does not have jurisdiction overseas, so we rely on our partnerships with our foreign law enforcement partners. but the fbi can't throw on our raid jackets, and walk into a sovereign nation, and execute an arrest warrant. narrator: the fbi would have to request that italian authorities arrest and extradite urea, something agent kowalski says wasn't going to happen. the crime for which she was charged federally is a death penalty eligible charge. and the country of italy does not

extradite for any crimes that carry that potential sentence. narrator: agent kowalski believes urea's move to italy was a calculated maneuver. was that the fbi's working theory, though, that she was living in italy because she knew that was a place she could go that she could be safe from extradition? yes. she selected that place purposefully. narrator: he also says having those twins was part of the ploy. she had children there, it's our belief, as a means to justify her citizenship in order to stay there. narrator: it appeared as though urea had outsmarted the federal authorities and was perhaps even thumbing her nose at adam's family and friends. i can honestly tell you, she's one of the very few people i ran a in my almost 27 years in the fbi that i would say that are very evil and conniving, calculating.

narrator: but for all her alleged planning to elude the fbi, there was something, or rather, someone urea had overlooked, abe anhang now, here's an older gentleman who is smaller in stature. but what was your impression of him? adam's dad, abe, was just such a brave man. abe may a small man, but he is a powerful, smart man, able to modulate his emotions, strategic. do you think urea even knew what was coming her way? absolutely not. narrator: abe was not about to give up his pursuit. she couldn't run off to europe and start a new life all over again while we buried our friend and abe buried his son. it wasn't about retribution. it was about justice. and abe didn't stop. narrator: coming up, abe tracks

urea on his own and shares what he learns with the fbi. she lied about her life the minute she showed up in italy. narrator: when "dateline" continues.

you waiting for? narrator: urea had carved out a new life for herself in italy, a country, with laws that prohibited her extradition because the charges she faced carried a potential death sentence.

all this, i think was planned out in her head. i mean, every move she made was calculated. narrator: the ongoing saga was taking a toll on adam's family and friends. it felt like it was very unfair. she's indicted. we know what she's done. and yet she still gets to go on living. narrator: but the fbi agents pursuing urea were not giving up. some, like special agent scott patterson, felt a special connection to the case. his even predated his career as an agent. in fact, it was our original "dateline" report from 2008 that first brought this story to his attention. he was in the army serving in iraq when he saw it and says he was touched by abe's loss. i can't believe the father lost his son, and the things that adam was doing for that island, and how his life was taken. narrator: patterson, who was contemplating leaving the military for a career in law enforcement at the time, says the story made him want to work the hard cases,

help the anhangs of the world. i was kind of on the fence if i was going to join the fbi or not. i just remember seeing it and thinking, you know, like, that's the type of work that i want to be doing. narrator: after joining the bureau, agent patterson volunteered to work in the san juan field office. he had no idea that the fbi was actually investigating the murder case that had helped shape his decision until it landed on his desk. we were handed a bunch of new cases. and i'm sitting there at my desk just reading through this thinking, like, i know this case. i know this case somehow. and i remember just logging on the computer and looking it up. and i'm like, oh, that's the pink skirt murder. narrator: it was a strange twist of fate, and it became agent patterson's top priority case. one of the first things he did was call abe. i remember like the first phone conversation i had with him and just still the grief in his voice. yeah. like, that cut me. narrator: he made a promise to abe.

i told him, whatever it takes, like, we will get her. narrator: but agent patterson didn't yet fully understand who he was up against. urea was in italy and untouchable. the fbi's hands were tied. abe's however, were not. the fbi did a tremendous job. i mean, they did an incredible job. but they don't have jurisdiction in italy. so i had to go out and hire at my expense and everything else, the investigators in italy. narrator: abe refused to wait for urea to trip up. he hired private investigators to keep tabs on her and report back to him. abe would put off his own retirement so he could fund his investigation. and it had to be done because no one else was doing it. narrator: abe's investigators surveilled urea. these pictures of her are from one stakeout. the investigators documented where she was living, where she was working. it was like abe became singularly obsessed

with solving the crime. i'd probably use the word, determined more than obsessed. he was just like a machine, just stayed on top of it, wasn't going to let it go until it was done. did you ever tell him, abe, maybe just let the fbi-- let the police deal with this? - no. - it wouldn't have mattered. what did you find out about the kind of life she had built for herself there? she wasn't in poverty. she was able to always to make some money and somehow have a good life. narrator: abe fed the information gleaned by his private investigators what amounted to urea's daily routine to the fbi former fbi assistant director, carlos cases. we knew the italians were not going to extradite her. that's why i give abe all the credit in the world because he took it upon himself to essentially track her for us and tell us what she was doing, who she was associating with, and what her movements were. we were never asking mr. anhang for any information

the fbi agents made it clear that the information from abe's investigators was not solicited and not automatically taken at face value. so it was helpful, but it was also information that you had to then work on your own and to corroborate? yeah, it was extremely helpful information and very much appreciated. it was just information that we would take. and then we would have to figure out what was factual and what wasn't. narrator: the agents learned that urea's boyfriend and father of her twins had found out through media reports about the accusations against her. not long after, urea moved out of the house with the girls. the paper started to reveal that she was the [non-english],, black widow and that she sought refuge in the jewish community. narrator: in florence's jewish quarter, urea passed herself off as a jewish widow, whose husband had died in an accident. in fact, when she married adam, urea agreed to convert to judaism, but never did.

you know, she lied about her life, you know the minute she showed up in italy. in puerto rico, we call it ay bendito factor, just the-- ay bendito. oh, poor thing. yeah, exactly. it's this mother of two. like, how could she be charged of this crime? and was telling people she was jewish. poor me. look at me. they're accusing me. and i'm just a widow. i'm just a jewish girl trying to get help. and my husband was killed. and here i am in florence. and for the jewish community, there they felt it was a mitzvah to help her. i mean, it's part of-- you have to help a widow. it's an obligation to help a widow. and she knew that, so she was playing that card. she played all of them too. all of them. narrator: assistant us attorney, ruiz-santiago says urea used false birth certificates to perpetuate her ruse. and that was done with the intention that she obtained a certification from the jewish community of florence stating that she was a jew and her daughters born in italy were jewish, so that she could then relocate from italy to israel.

narrator: perhaps planning her next escape, urea never moved to israel. but over the next few years, the fbi continued to keep tabs on her, largely through information provided by abe's investigators. and one piece of information in particular was game changing. she did a fair bit of traveling. she loved to travel. she wasn't confined to italy then? oh, no. she went to spain. she went to switzerland. she went to england. she was in gibraltar. she was in israel once. we tracked her. narrator: all those trips she was taking gave the fbi a new opportunity to break the case because a number of european countries have different policies regarding extradition. so if she was arrested outside of italy, there would be a good chance of getting her back to puerto rico. interviewer: had the fbi tried to capture her in a restaurant any of those points in her travels? we did. narrator: but by the time the agents would get wind of where urea was and filed the paperwork with the local authorities, it was too late.

she was already back in italy. interviewer: how close did you get? we had officers in one of those countries right outside our hotel door. but the steps and the process that you need to go through with such fast changing information, it was really tough. how frustrating is that, though, for the fbi agents knowing that she's there, but she's untouchable? there's nothing we can do to get her. it's very frustrating, natalie, but we don't get bogged down in frustration. we find a way to get it done. narrator: the game of cat and mouse between urea and the fbi continued for years. but by 2013, five years after her indictment, the fbi decided to stop playing defense. it was time to go on offense. it was time for a hail mary. did you think it was going to work? honestly, i gave it a 50/50 chance.

i'm jessica layton with the hours top stories. authorities are investigating the plane crashing kazakhstan. at least 38 people were killed. early findings save the plane collided with birds. thousands of ukrainians are without heat and power after russia launched an attack on their power grid. now, back to dateline. to d.

we were in a defensive posture because she had been an elusive person for so long. knew we could not arrest her in italy, or the italians would not extradite if we had her arrested in italy. narrator: even though urea would leave italy and travel throughout europe, the agents never had enough lead time to coordinate her arrest with the local authorities, so they decided they needed a new strategy. they would set a trap. carlos cases was the special agent in charge of the san juan field office in 2013. the agents came to me one day and said, boss, we have this plan that we are developing because we believe that we have the ability to get urea to travel from italy to spain. narrator: the agents felt confident spain would arrest urea and extradite her to puerto rico.

we developed this strategy to exploit what she was doing in her daily life. and she was a tour guide, and she was traveling all over europe and elsewhere. and she would provide tours for traveling jewish groups. narrator: the strategy was simple. present urea with a business opportunity, come to spain to meet a group of american tourists, and guide them as they traveled through europe. i told my agents, all right. we're getting all the approvals. we're doing this. narrator: the agent set up a fake tour group that was heading to europe and in need of an experienced guide like urea. so you conducted a good old fashioned sting operation? a good old fashioned sting operation in which we need to design something that's plausible for her to be able to bite into. it's not a lot of bells and whistles. there's not drones. there's not wiretaps everywhere. there's none of that stuff. it's hey, let's use what we know about urea vasquez. what are her vulnerabilities? what are her motivations? and let's develop a strategy to exploit those to get her

to a place where our arrest can be executed with a little bit less red tape. narrator: her weakness, they decided, was money. and so they planned to dangle a job offer too good to pass up. it had to be very meticulous, natalie, because we couldn't run the risk of her getting suspicious, and then backing out, and not traveling. this was a well choreographed and a very thoughtful operation in which there was a manifest that was going to be a multi-stop tour to multiple countries. and there were, down to the confirming what on the agenda for each day would have-- she would be responsible for by providing these groups, restaurants, kosher restaurants, she would have to go to to take the jewish travelers at each location. it was-- wasn't bulletproof, but it was strong. narrator: but was it enough to convince urea? the fbi agents contacted her through intermediaries that she had worked with before. interviewer: so she trusted these people?

she had trust. narrator: through those intermediaries, the agents negotiated with urea for two months. finally, she took the bait and agreed to fly to spain to act as a guide for what she thought was a group of jewish american tourists. did you have confidence in the plan at that point in time? when you all saw this on paper and you saw the email exchanges going back and forth, did you think, we're really going to get her this time? i was pretty confident. so i remember the day was coming. and i was just worried that she wasn't going to get on the plane. narrator: but when the day arrived, the agents got word urea had boarded the plane and was en route to spain. she's traveling to spain, arrives there thinking she's going to meet a bunch of travelers. what happens? authorities from the spanish national police are there plain sight in the jetway to take her into custody. narrator: the sting operation worked. on june 30, 2013, after five years on the run and almost eight years after adam's murder, urea vázquez-rijo

was finally in custody. and what was that moment like for you? i was ecstatic. i never thought that we were going to be able to get her. narrator: urea's arrest triggered phase two of the operation. as soon as i received confirmation that she was in custody is that then we executed arrest warrants on marcia and jose in san juan. narrator: agents swarmed the homes of urea's alleged co-conspirators, her sister, marcia, and marcia's boyfriend, jose ferrer sosa. and so it really was like an internationally choreographed simultaneous arrest and a good day for the fbi, but a tremendous day for the victim's family. narrator: carlos cases delivered the good news to abe and his family. i was so surprised, that i didn't even say thank you to him. i dusted him off a bit, which was not right. you were in shock. i was in shock. i mean, it had been years of pursuing her. and finally, they had her.

they had her. but what's it like to hear those words, we have her. she's in custody. oh, wow. oh. finally. almost the opposite of the other one, you know? you know, your son's dead. narrator: urea vázquez-rijo was in a spanish jail cell, her sister and her sister's boyfriend locked up in san juan. all faced conspiracy charges connected to the murder of adam anhang. but if you thought that this was the end of the saga, you haven't been paying attention. by this point in this investigation, i'm not surprised by anything because it's just a crazy twist after a crazy twist. narrator: coming up-- she used her sexuality. narrator: -- urea's little surprise. how does that happen? well, i don't know because i've never been to that prison in spain. narrator: when "dateline" continues. let's monopoly go!

narrator: the fbi's meticulously planned sting operation had worked. urea vázquez-rijo had been arrested by spanish authorities after five years on the run. but barbara anhang had learned in the year since her son's death that urea was nothing if not cunning. barbara, did you think, ok, the end is in sight? no, i didn't. her behavior is extremely mischievous and slippery.

so you already were expecting something else? yes, but i couldn't tell you what it was. but i knew something would happen. narrator: call it a mother's intuition because while urea was in a spanish jail fighting her extradition to puerto rico-- -- urea went back to her playbook, the one that she used in italy, and ended up getting pregnant while in prison. how does that happen? well, i don't know because i've never been to that prison in spain. what i do know is that she got pregnant by another inmate that was there. and is it the fbi's belief that she had this child again as some way to try to delay the process against her? yes. she did it in italy previously by having twins. and it's our assessment that she did it again to have some legitimate reason why she shouldn't be removed to the united states. master manipulator. master manipulator. narrator: the pregnancy meant that urea's extradition, if it happened, would have to wait at least until

after the baby was born. interviewer: so when you heard she managed to get pregnant in prison in spain-- oh, i smelled that one so quick. you knew it was coming? oh, i knew it was coming. she used her sexuality, you know, in such a calculated way. it goes to show the sick, evil individual that really was only thinking about herself and how to spare herself. narrator: the baby, a girl, was born in the summer of 2015. just weeks later, agent kowalski got the word. all of a sudden, the spanish court says, we're done. she's being extradited. and we were told that in past experience, unless you act immediately, there's potential that the removal evaporates. narrator: but the fbi was ready. i don't want to risk transporting her on a commercial flight back to the us, particularly, with a small child because my concern was that she was going to cause a scene while boarding the airplane, and the captain was going to say, get out.

i don't want-- i don't want this on my flight. too risky. narrator: any delay in the extradition could give urea another chance to stave it off and remain in europe. i called fbi headquarters and requested to use the fbi director's plane to fly to madrid, pick her up, and then bring her back straight to san juan. narrator: headquarters approved the request, so agent kowalski jumped on the director's plane and flew to spain to pick up urea and her baby. finally, they were bringing her home. he was tight-lipped about what urea said on that flight. i'm not able to discuss specifics on the conversations, but she presented as someone that was in disbelief that she was actually apprehended. and she presented as someone that, in her opinion, did not believe that she was guilty for the crimes that she was charged. what satisfaction did you feel on that flight back, though, knowing she's sitting right there next to you and in custody? i felt very fortunate to--

honestly, sitting there and thinking about it, when we land abe anhang finally has, not closure, but has some sense of justice, that he came to the fbi in 2007 and said, i need your help. and we conduct an investigation over several years. and we're taking the director's plane over to spain bringing her back. and the fact that you're flying in the director's plane, i think, conveys how important an operation this was to the fbi. extremely. extremely. narrator: carlos cases has met the plane on the tarmac when it landed in san juan. and so i went up into the plane. i thought i was going to see a a contrite and a sad urea with a somber mood. far from it. she was smiling. narrator: years of hard investigative work had culminated in this moment. the fbi had their woman. agent kowalski says urea was given the chance to spend some time with her infant daughter before they would be separated, perhaps, forever.

and she requested that she use that time to make herself up because she was fully aware that there would be a tremendous amount of media coverage and cameras upon her arrival. so she was more concerned about making sure she looked good than about spending her last moments with her child? yes. interviewer: did that surprise you at all? it did not surprise me. it's the queen of selfish. yeah. narrator: it was september 24, 2015, almost 10 years to the day since adam's brutal murder. for the anhang family, abe's relentless pursuit of urea had come to this moment, urea in shackles brought back to finally face the charges against her and face abe himself in court. when they finally brought her back, somebody said to me, what words do you have for her? i said, welcome back from your european vacation. narrator: but urea was not about to go down without a fight and without trying to do

what she did best, exploiting people for her own personal gain. would the jury be next? narrator: coming up-- she thought that she would win the jury over and she would get away with it. narrator: -- urea on the stand when "dateline" continues. long after guests leave, viruses and bacteria linger. air fresheners add a scent. but only lysol air sanitizer helps erase the trace, eliminating odor and killing 99.9% of viruses and bacteria in the air. scent can't sanitize. lysol can. my moderate to severe crohn's symptoms kept me out of the picture. now i have skyrizi. ♪ i've got places to go and i'm feeling free. ♪ ♪ control of my crohn's means everything to me. ♪ ♪ control is everything to me.♪ and now i'm back in the picture. feel significant symptom relief at 4 weeks with skyrizi, including less abdominal pain and fewer bowel movements.

of hiring alex "el loco" pabón to kill her husband, adam anhang. she pleaded not guilty, as did her two alleged co-conspirators, her sister, marcia, and josé ferrer sosa. urea didn't want to talk to "dateline," but her mother has been an outspoken defender of her daughters. interpreter: to me, my children are innocent. narrator: she insists her daughters are victims of a corrupt legal system. interpreter: there is justice here for people with a lot of money, but not for others. modest people on the street have no chance. narrator: after three years of procedural delays and an act of god named hurricane maria, the trial for urea and her codefendants finally began in august 2018, 13 years after adam anhang was murdered. for me, the case was about greed. narrator: assistant us attorneys jennifer hernandez vega and jose ruiz-santiago

prosecuted the case. it was important for the jury to understand why would this have occurred? the fact that at the time, they were about to get a divorce when the murder happens is all about her wanting to have more. narrator: the trial was held in a federal courthouse just blocks from where adam was murdered. was abe in the trial the whole time and his wife? he sat right behind me in the first row. narrator: abe says it was unnerving sitting so close to urea at her defense table. it's about 15 to 20 feet away. that's how close it is. and we made eye contact a few times. narrator: urea, for her part, appeared to be playing a part. she played a character. and every day, she would come very well dressed with all her makeup on. narrator: urea, it seemed, wanted the jury to see her as adam's glamorous, yet grieving widow. she came in with her hair blow dried.

she was something else trying to have the ay bendito work for her, you know, poor thing. narrator: with no physical evidence tying urea to adam's murder, the prosecution's case was circumstantial. and with urea sitting at the defense table, it was by no means a slam dunk. but after a 10-year investigation, the case was voluminous in scope from testimony about the troubled nature of adam and urea's relationship, to the numerous phone calls urea made to adam to convince him to have dinner with her that fateful evening, to the prenuptial agreement granting her $8 million should adam die. the prosecutors also presented something else they believed pointed to a conspiracy, a handwritten letter by alex pabón. and this letter was addressed to marcia. then the point of this letter is saying that he had done his part of the plan, and now it was their turn to then

pay him for what he had done. narrator: of course, their star witness was alex pabón himself, who had already pleaded guilty to participating in the conspiracy to kill adam. he told the jury how urea and her co-defendants hired him to do it. although, he said they never paid him as promised. he was one of the last prosecution witnesses to testify. we believe that by putting alex at the end and showing all the motive that urea had and all the steps that she took to have adam murdered before sitting down alex, it would be easy for the jury to comprehend, yes, this is what actually happened. narrator: but the defense tried to convince the jury that something else happened. i believe the defense strategy was to paint him like he was so crazy, that he did this. this was a random killing. narrator: the defense said alex "el loco," the crazy one, was just that, crazy

and had acted alone in killing adam. and they dismissed that letter, which had never been delivered as the ramblings of an unstable killer. in fact, they insisted there was no evidence of any communication between pabón and the three co-defendants. but the biggest moment of the trial came when urea, herself, took the stand. she had spent more than a decade claiming to be adam anhang's grieving widow. now was her chance to convince the jury. she felt secure that if she had the opportunity to talk to those jurors, that she would make them believe that she, in fact, was in love with adam anhang and she had not participated in these events. narrator: urea testified that she had never even met alex pabón, let alone, hired him to kill her husband. and while she admitted that she and adam had marital issues, urea insisted they were devoted to one another

and were working things out. urea also testified that she had not fled to italy to elude authorities, but rather, to pursue her dreams. adam's friends weren't buying it. and how would you describe her on the stand? she was the narcissist that we knew she was. she thought that she would win the jury over and she would get away with it. narrator: but what would the jury believe? you always worry about a jury because one person can just, for whatever reason, decide to go the other way. and you always worry about that, absolutely. narrator: after two days of deliberations, the jury reached a verdict, guilty. and then nearly 15 years after the death of your son, finally, those words, guilty. what was the emotion in that courtroom? it was quite a moment. yeah, it was. narrator: the sentencing was held a few months later after the victim impact statements.

as abe was walking past urea, she spoke to him. she says to me, are you happy now? she has the audacity. well, i knew what she was trying to do. she was trying to provoke me, right? what did you say? i just said shut up. now, in retrospect, there's lots of other things i could have said. yeah. if you're looking for a symbolic moment that sort of sums it up, it's right there. yeah. narrator: urea was sentenced to life in prison, as were marcia and josé. although they had been convicted of a lesser charge, all three are appealing. i don't hate ari, but i sure hate what she did to us and our family and what she's done to her own family. i mean, look what she's done. narrator: think about the children she left behind. right. i mean, who's going to look after all these kids? i mean, she had no regard for the kids she was bringing in to this world other than it would help her run away.

narrator: urea's twins are with their father in italy. her daughter born in spain lives in puerto rico with urea's mother. for abe and his family, the convictions marked the end of a journey filled with pain and loss, but also, with determination, determination to fulfill a vow abe made the day he learned his son had died. we can say now there is justice for adam, but will that bring peace at all for abe? i think it brings relief, some level of closure. but no, i don't think it will ever bring him, or becky, or barbara peace. i have a photograph of him that sits on my desk where i see him at his joyful best, and his optimism, and how beautiful a person he was. it reminds me of what we lost and what

he could have been today. to know abe is to know that he'll start writing the next chapter now. and whereas, the last chapter was about seeking justice for adam, i'm certain this next chapter will be about living adam's legacy. "down on the ground. so i did. i could be dead right now. i wish i had put my face over his so he could look at me. josh mankiewicz (voiceover): she had to relive it all for the cameras. she was a new bride, married just six days. then came that horrible night.

i see kind of a dark shadow.
