Love, and her husband. Its terrifying. You wonder what kind of story were you involved with . Jealousy, betrayal, revenge. Who had the motive to kill one person and one person only . There is no perfect murder. Im lester holt and this is date line. Heres andrea with the fire inside. Reporter its been said that everyone has three lives, one public, one private. And one secret. But in 2011 two new york area families had all three exposed when their lives collided in a lurid tale of sex and jealousy fire and murder. Its terrifying because then you think, well, hey. It could happen to me. It could happen to any one of us. Forever, those people forever their souls will be marred and torn by these events. Its hard to know exactly what happened that day at that door. Reporter that day was march 6th, 2011 a raw and rainy sunday in tea neck, new jersey. Henry rodson was the first to spot trouble. Reporter what was happening that night . I had a flat tire earlier in the day, and i had to come back to fix it. It was raining, it was windy. It was just very miserable. Reporter when we met up with rodzen almost five years after that gloomy night, the weather had changed, but his recollections had not. Started puttin all the all my tools away. For some reason, i just happened to look up, and i saw smoke goin across the street. Reporter from the corner house . From goin across from the corner house, goin across through right. So i said, okay, well lemme take a quick jog over, see whats goin on. Reporter what henry saw, once he reached the corner of terhune and elm, removed any doubt for the former volunteer firefighter. As soon as i saw that there was a bright amber glow, i knew that was definite fire. So i decided to just quickly run back to my girlfriend, i said listen, call 911, theres a house thats on fire. Elm street in teaneck and its the back of the house is on fire. Okay, get everybody out of the house. Reporter youre a former volunteer firefighter. Are you thinking, ive gotta spring into action here in case someone needs to be rescued . I started yelling, i started pounding on the door as hard as i could, just to see if there was any activity, see if anybody was home. Reporter anything . All the lights were off, everything was quiet. When i went around to the side, the amount of smoke and the amount of flames the basement was fully engulfed. Reporter you have no gear nothing i also noticed that the neighbor had a spigot nearby. I was pouring water on the windowsill, but that fire inside was rolling. [ sirens ] reporter once inside the Burning House firefighters discovered a badly burned body in a basement bedroom. It was shortly before two in the morning, when Bergen County arson investigator sgt. Terry lawler got a wake up call from his boss. We have a fatal fire in teaneck, new jersey. Gives me the address on elm avenue and says, im headin out there. And ill meet you there. Reporter by the time he got there the victims body had been taken outside. The body had suffered severe burns on the front of the body, more so than the back, which wasnt bad as badly burned. Reporter they would soon learn that the victim was the owner of the house, a 59yearold man named rob cantor. His body had been found in a basement bedroom the same place where henry rodzen spotted the fire. Lawler thought it strange that cantor had died so close to where the fire started. Usually, you see healthy, middleaged males and theyre tryin to get away from the fire. So, maybe theyre overcome by smoke. Reporter lawler wanted to look around the basement where the body was found, but it was flooded. We had to wait and have the Fire Department pump some of the water out so we could enter the basement and conduct our investigate. Reporter that job would take several hours giving detectives from the Bergen County major crimes unit, time to question neighbors. Canvassing is the most time consuming thing, but you have to do that right away. Reporter former Bergen County prosecutor, John Molinelli was on the scene in those predawn hours. Unlike District Attorneys Office nationwide, in new jersey a county prosecutor is not just the chief Law Enforcement officer of the county, but also directly oversees the investigation of all major crimes. Reporter molinelli says from the first time he laid eyes on rob cantors body, something didnt look right. So he asked the medical examiner to fast track an autopsy. You could see some indication that this wasnt just somebody who was just smoking in his bed and then the bed lit fire. Reporter what was your gut telling you as to what this could be . What youre looking at . The first thought was, well, whoever did this act lit the crime scene in an effort to to frustrate Law Enforcement because dna evidence is always important. Reporter later that morning autopsy results confirmed the prosecutors hunch. The medical examiner had found a small hole at the base of rob cantors skull, and bullet fragments inside. Who killed rob cantor and why, were questions that would lead investigators far from the still smoldering house on elm avenue. When we come back, what had happened in that house . It wasnt just a shooting, it was an execution. Reporter diabolical . Yeah, despicable. Reporter turns out, there wasnt just one case of fire and murder in this county there were three are those other two murders the first thing that come to your mind . There was certainly a discussion.

Reporter by all accounts, rob cantor, the man whose body was found inside this Burning House, was an easygoing guy loved by all. I never met the man, but im sorry i never met him, because every person ive spoken to says he was a great guy and i believe that. I believe he was truly a great guy, because of the impression he left on his family and his friends. Reporter an avid guitar player, rob had worked as a Software Engineer for verizon. For 26 years he and his wife had lived on this street in teaneck. Theyd raised their two daughters here. Now, investigators had to figure out who wanted him dead. It wasnt just a shooting, it was an execution. He shot him from behind execution style. Diabolical . Yeah, despicable. Reporter back at the scene of the fire, investigators found a bullet casing for a. 380 caliber handgun. An analysis of a comforter also found in that bedroom revealed something else. And the forensic scientist was able to determine that ethanol was on the comforter. Reporter that suggested an accelerant had been used to set robs body on fire. For Bergen County prosecutor John Molinelli, that was a disturbing development. Thats because this was now the arson homicide in Bergen County in less than a year. Are those other two murders the first thing that come to your mind when you see this crime scene . There was certainly a discussion and a deliberation on the topic, certainly within the first few weeks of the cantor murder. Reporter on the surface, there were haunting similarities. In april of 2010, 69yearold Dolores Alliotts had been found stabbed to death in her burning home. She was a woman that was known to leave her house open. She did not lock her doors. It could have been a stranger from the street. Reporter a few months later, 74yearold joan davis, a well known Community Activist seen here at a Teaneck City Council meeting was found strangled and stabbed to death in her burning home. We had always believed that the person who murdered joan davis was someone that she let into the house. Reporter and now, rob cantor had been found dead in his burning home also in teaneck. Very early on we were looking at you know, could rob cantors killer be the same killer in teaneck with ms. Davis and in Palisades Park with ms. Alliotts. Reporter the answer was unclear, at first. But detectives did have leads in the cantor case. A neighbor had reported seeing a stranger near the cantor home shortly before the fire. Did you hear about the stranger that was in the area . Yes. Can you tell us about that . Yeah. We werent able to track who the person was and we tried through canvassing to trace, but we never had him coming outside of the house or we never had him going inside the house. Reporter according to robs friends, someone had been stalking him. About a year earlier, they said rob told them hed gotten some creepy emails, which suggested that he was being watched. This is one of them rob, saw you this morning with this woman on upper west side. How are things with her . Very, very strange email addresses, strange names. One was eoralld. Another one was eor247. Reporter assistant prosecutor Brian Sinclair who heads the countys computer crimes unit, says the emails seemed intended to intimidate. Imagine that rob was getting these emails, being quite troubled that somebody knew where he was at a particular time, you know, who he was with. Reporter with that in mind, the prosecutor and his top detectives decided to take a hard look at robs personal relationships, starting with his wife of 27 years, Susan Kirschenbaum, seen here in happier times. Its sergeant love. Reporter sgt. Cecelia love was the case detective. What was going on in their lives at this time, susan and rob . Well, they were living separately. Um, they had still had a relationship, because they had the you know, the two daughters together. They were divorcing . Yes. And you know, they were they had been discussing selling the house, you know, dividing up assets. That can get tense, even for the best of relationships. Absolutely. Did you need to take a close look at her . In the beginning, you know, you always would think, it could be his his wife or his exwife. Reporter not only that, robs friends told investigators that he had a younger lady in his life. A french woman named Sophie Meneut who lived across the river in manhattan. Was this divorce because of the other woman . No, it definitely wasnt because of the other woman. They had been talking about divorce before, uh, sophie. Reporter the detectives had a lot of questions for the women in robs life. Coming up the estranged wife. We did bring her in and speak to her. And the new love. She was crying. She was shocked. Police wondered did either have a motive for murder . When dateline continues. Hey, leggo my eggo. Uh uh. Not ccc cause i have the and i i. Thats a lot. Raisins. Really . What just happened here .

Reporter after rob cantors murder, investigators searched for a link between his death and two other arson homicides in Bergen County. They couldnt find one. So detectives intensified their focus on those whod been closest to rob. Was this high priority . Absolutely. We interviewed the friends and family members. Lots of people to talk to . Yes. Reporter at the top of the list were the two women in robs life. His lover Sophie Menuet and his estranged wife, Susan Kirschenbaum seen here in a facebook photo. We did bring her in and speak to her. Who wanted this divorce . Rob or susan . I think they both wanted it. It was a mutual decision. Reporter still, the detective says, robs estranged wife seemed devastated by his death. According to susan, shed been at home and on the phone with a friend on the night of the murder. Nothing really led us to believe that she had any involvement in this. Reporter over in manhattan, detective love met with the other woman in robs life, Sophie Meneut. She was crying. She knew that he was deceased. Did you tell her that he had been murdered . Later on in the interview, yes. What was her reaction. She was shocked. Like anyone would be if you found out that information. Reporter sophie told the detective that shed seen rob hours before he died. Rob, with his two friends had gone to new york city to meet sophie and her daughter, her eightyearold daughter at a museum. How open is sophie to you . She was a very open person. When i asked her why would rob cantor be found in the basement bedroom, she broke down and she began to cry. What was significant about the basement bedroom . That was the place that she and rob had consummated their relationship. Reporter the french born sophie was 40, 19 years younger than rob. Theyd been seeing each other for more than a year, she said and had a lot in common. Running, philosophy and science. But there was one problem. Sophie was married when they met and raising three daughters, ages 5 to 10, with her husband, tony tung. Sophie was living a bit of a secret life . Initially, yes. But it wasnt too long before it you know, it all came out. Reporter sandra milon, a close friend of sophies husband, was living in france when she heard about the affair. I was sad. You know, my friend was really going through a terrible time and i was so far away. Reporter sandra met tony tung when she was living in new york back in the 80s. She says when tony first met sophie, he fell hard. They were a beautiful couple. I was very happy for them and i was very happy for tony. And then sophie being french, so that was great. Reporter when contacted by investigators, sandra told them all she knew. Sophie had the career, an important job in finance with an international firm. Tony stayed home with the kids. He served as president of the pta at their school. Did tony share with you the joys of being a dad . Yeah, cause we talked about it all the time. He was so much full of love for his girls and since he was the one raising them, he was there 100 of the time. Hes mr. Mom . Yeah. Reporter once the girls were older, tony wanted to work, too. So, with sophies financial help, he opened a computer store. Hopes were high, but business was bad. And sandra says when tony learned sophie was having an affair, his world fell apart. He was really, really hurt. But trying to do his best for the girls, as always. Reporter the couple soon went their separate ways. But when rob cantor was killed a year later investigators came to see tony. The reason were here is because there has been an incident that happened in new jersey. Okay. Reporter the detectives told tony he was just one of several people they were questioning. Dont take this the wrong way. What . Was your wife cheating on you with rob . Yeah. Reporter tony admitted that hed been upset when he first learned of the affair, but told detectives hed moved on. Tell you if my wife was seeing somebody else i wouldnt be too happy. Oh no, no. The pain is gone. Reporter according to tony, hed been at home alone the night before. I was on facebook, reading email and watched the news. Reporter the detectives werent convinced. But with no smoking gun, no witnesses and no dna, it seemed unlikely this case would be solved in a matter of days, or even weeks. Still, when months passed with no arrest, robs friends became impatient. Outrage today in new jersey over a perceived lack of progress solving a murder case. Reporter first they hired a private investigator. Then they petitioned the governor. When that didnt work, they picketed outside the Bergen County courthouse. One of robs coworkers spoke for the group. They keep telling us, give them time or dont interfere. we hired our own world Class Private detective. They said hes not doing a good job. Then, who is doing it . Everything we do, they say dont do it. We are so frustrated. Was it moving slowly, as they claimed . Well, im sure for them it was moving slowly. But you know, every investigations different. Reporter in fact, this investigation was a lot further along than the protestors knew.

Reporter for more than a year rob cantors friends had been telling detectives that robs murder was related to his affair with a married woman. The womans husband, tony tung. They said was the jealous type. A man whod actually come to teaneck to confront rob. He had made visits to rob cantor at his home to talk about this relationship and ask him to end it. Reporter this is tony tung. He admits he did some foolish things in the wake of his wifes affair, but insists murder wasnt one of them. He says he was surprised investigators suspected him. Did you tell them everything . Yeah. I mean, why would i lie about stuff like that . I didnt do anything wrong. Reporter according to tony, he only went to robs home to put a face with the name. Thats a bold move. I want to know who the person is. So you ring ring the doorbell. Yeah. I say, you know, my name is tony. Im sophies husband. Can i come in and talk to you . He was like, okay. Yeah, sure. So i walked in. What do you two talk about . First we, like, small talk. Just family stuff. This sounds crazy. No one would believe it. Reporter as awkward as it sounds, tony says, the two men actually found common ground. Youre talking about cooking as well . Little bit. I made a comment about his stove. We had a lot in common. We both like foods. Obviously, we both love sophie. Reporter for several hours, tony says the conversation was mostly light chit chat. But in a strange turn, tony asked to see the basement bedroom where rob and sophie had sex. Why go to the room where i mean, thats almost like torture. This is where he had sex with your wife. Im confronting someones having an affair with my wife. Might as well see the rest of it. Reporter what could you gain by seeing that room . I guess, in a way, how he treat her. I remember, i was a little upset. Reporter that it was a room in the basement . Yeah. It was like this like, you took sophie down here . What the hells wrong with you . You cant go to a hotel . Reporter how angry are you when you leave . I was like, well, id like you to stop seeing my wife. Reporter what did he say . He said, i cant answer you right now. Reporter remarkable, right . But get this, tony says he went back two more times. And third time was like, you know, this is pointless. And hes still letting you in . No, that time we were on the patio. He actually was like, no, tony, why dont you just call me . Youre becoming a regular visitor at your your wifes lovers house. Well, he was more worried i think his wife is still living there. I mean, this sounds all very cordial. It is cordial. Reporter tony insists that was the last time he saw rob. That was a year before the murder. Where are you that night . I went home. Youre just hanging out at home . Yeah. Doing what . Watch tv, reading, wash dishes, clean the computers. Reporter for months investigators searched for evidence that tony had crossed the river from his home in manhattan to new jersey that night. They checked cameras at all the bridge and tunnel crossings. They poured over bus schedules, taxi and limo records. But in the end, they came up empty. You had no bridge video, you had no taxi receipts, you had no witnesses. You had nothing actually physically placing tony tung in teaneck. Youre right. We didnt have him at the George Washington bridge. We didnt. Reporter still, the investigators kept digging. Remember those anonymous emails that had been sent to rob, suggesting that he was being watched . Turns out they all traced back to tony tung. He created all of these on the same day, which was the same day that he learned about the affair. He used these email addresses to start contacting mr. Cantor at some level just try to shame him into stop having an affair with his wife. Reporter that wasnt all. A close look at tonys computer indicated a massive amount of data had been destroyed on the night rob cantor died. What mr. Tung was doing, less than three hours after the murder, was obliterating data. He was doing the digital equivalent of lighting it on fire. Reporter that seemed more than coincidental. So in may 2012, 14 months after the murder of rob cantor, the Bergen County prosecutor decided it was time to arrest tony tung. I answer the door in my boxers, and my tee shirt. Detective yank me out of there. Gun to my temples. Slam me against the wall. What the heck . Youre mr. Mom. And now youre accused of murder. Yeah. And burning the house down. Reporter in the fall of 2015, tony tung finally went on trial for murder. Rob cantor had been dead for nearly five years by then. Given that prosecutors still no physical evidence connecting tony to the crime, getting a conviction looked to be an uphill battle. Coming up new evidence captured on camera. Something was taken from that car. That something is the gun reporter and on the stand, a star witness. They told me there was a fire reporter the two women in rob cantors life finally, face to face.

Almost every day for the next two months, robs friends and family would be there. Tonys friend sandra milon, who now lives in france couldnt come to new jersey to support him. Did you follow the trial . Were you able to over the internet . I was able to. Yes, a little bit. Reporter for sandra, the man she read about online accounts, bore no resemblance to the person shed known for 30 years. Did you think for a second that, oh, my gosh. Maybe i dont know tony as well as i think . No, no. Because um tony knew also that doing something stupid, as in going to kill this man, then what . Then you end up in jail for the rest of your life and is it really worth it . I mean what mattered for him was his girls. Reporter veteran prosecutor wayne mello, who was chosen to try the case obviously saw it differently. This case was about perhaps the oldest motive in the world, in this case she and he done him wrong. Reporter according to the prosecutor, tonys rage, simmered until one event finally set him off on march 6th, 2011, that day was the day tony learned that sophie had introduced one of his daughters to rob. This would be first time that a child of tung had met mommys friend rob. In a timeline, partially captured by security cameras, tony is seen just after 8 00 pm that night, talking with his daughter, cleo in the lobby her mothers apartment building. Cleo will tell her father oh, yes i had a lovely day today, mommy and i went to a museum. I met her friend rob. Time is now 8 20 p. M. Reporter almost two hours pass before tony is seen again. Mr. Tung, is seen on video parking his car at 10 10 pm. We see him on that video walk from his car to his residence. Then about 20 minutes later security cameras again catch a glimpse of tony. You will see him walk to his car. You will see him enter his car. You will see him spend perhaps two minutes in the car. You will see him walk to the corner. Not his corner. Hes not going back home, hes going to teaneck. Reporter according to police, tonys car never moved again that night. How do you think he got to new jersey . Oh, he definitely got to new jersey by car. And he definitely had help in some form. Reporter whats your theory . That particular form of help took is unknown, but there are many ways for an individual to get to new jersey without having a record of that trip made. Reporter the prosecutor argued that tony had plenty of time to make the 13 mile trip to teaneck and return in time to start destroying computer files. Just hours later, as that body has been recovered from the embers of a horrible arson, mr. Tung just happens to be feverishly erasing 170,000 bits of information on his computer. Reporter in spite of that the prosecutor said a critical piece of evidence was found on tonys email account. In november of 2010, just months before the murder, tony had emailed a friend in texas asking for help getting an ammo magazine for a. 380 caliber handgun. State your name for the record and spell your last name. Reporter though the friend never sent the magazine, the Prosecutor Says the email was significant. Mr. Tung just happened to have an interest in the precise caliber weapon that was the killing weapon in our murder. Dont you find that remarkable . Reporter though the murder weapon was never recovered, the Prosecutor Says this video seems to show tony exiting his car that night with something in his right hand. Something was taken from that car. That something i suggest to you is the gun. Reporter in one of the most anticipated moments of the trial, the state then called the woman at the center of it all, tonys now exwife Sophie Menuet. Please state your name for the record and spell your last name. Sophie meneut. Reporter perhaps no one in the packed courtroom listened more intently to sophies story than Susan Kirschenbaum, robs wife at the time of his affair with sophie. Where were you born . In paris. Reporter according to sophie her marriage to tony was already in trouble when she met rob cantor at a science lecture in the fall of 2009. I was wearing a tshirt that had paris marathon so rob said oh, you run. And he said oh, i run too and we started talking about that. Reporter as the weeks passed their friendship turned into something more. I knew that he had feelings for me and i started to develop feelings for him as well. Reporter sophie said, it was on valentines day weekend, 2010, that the relationship became intimate at robs home in teaneck. He said that there was a bedroom in his basement. It was a bedroom that the kids used when they were teenagers and so we went down in that bedroom and we made love. Reporter a few days after that sophie says she learned that tony had hacked her private email account and knew everything. Did mr. Tung question you about intimacy between you and rob . Yes. Can you tell us about that part of the conversation . He wanted to know where we had slept together, and i told him we slept together in the basement bedroom. Tony was really upset that i had slept with an older man in the basement. Reporter days later, sophie says tony told her he was going go to chinatown and buy a gun. He came back home with a brown paper bag and he opened the paper bag and showed me a gun. Could you tell if it had a magazine . No. Reporter a year later the prosecutor argued, tony used that gun to end sophies relationship with rob. The body of Robert Cantor was found in that basement bedroom on the remains of the bed where mr. Cantor had sexual relations with mr. Tungs wife. Reporter for her part, sophie says she learned of robs death the next day, when she got to work. There were voice messages on my voicemail and emails from robs friends. They told me that there had been a fire in robs house and that he was dead. Reporter it was in that moment, perhaps, that the two women in rob cantors life, two women who had never before met, bonded. When court adjourned that day, susan embraced her husbands lover. It was an emotional moment, because they really had never met before in person. And i think it was just validation that they both, you know, were on the same page. Reporter in closing, prosecutor wayne mello, returned to one theme he had pounded hardest during the trial. This murder could have happened no other way other than the murderer is seated before you. Reporter it was now the defenses turn to argue that for all the theory and conjecture, the prosecution had really proved nothing. Reporter coming up the stranger near the crime scene.

Reporter day after day, tony tung watched the prosecution portray him as a cold blooded killer. It wasnt a pretty picture and according to tony, it wasnt a true one, either. Theres a lot of bad things adding up here. Where he was killed. You wiping your computer hours after the murder. You going to visit him. Yeah, but i didnt kill him. Did you have someone drive you over to teaneck no. No. Reporter for sandra milon, the prosecutions theory that tony murdered his wifes lover out of jealousy, made no sense. Sometimes in crimes of passion, its you dont really think it through. Youre angry. Well, crime of passion when youre angry, that happens right then, doesnt it . Does it really happen over a year later when things are working out . Reporter turns out, that was the same argument, tony tungs attorney, Robert Kalish made to the jury. Why, he asked, would tony kill rob a year after rob had shown him the bed where he had sex with his wife . If he didnt kill him right there and then, he wasnt going to kill him at all. Because that was the time to do it, with his bare hands. Reporter according to kalish, investigators never seriously considered the possibility that someone else may have wanted rob cantor dead. Tony was the only suspect. Reporter another potential suspect, kalish said was the stranger that had been spotted near the cantor home shortly before the fire. Charles johnston was the neighbor who reported the man to police. I saw an older gentleman approximately 6570 year old white male with a red cap on and white hair. Was it someone from the neighborhood . No. Reporter Bergen County detectives never followed up on that, kalish argued because they only had eyes for tony. They just let it slide. Let it slide because they got their man. Reporter on the night of the murder, kalish said, tony was at home alone watching an Indiana Jones marathon on tv. As for the late night destruction of all those computer files. Kalish says that was just an unfortunate coincidence. Its just just normal that he decided to to do to do it at that time. What time did he delete the material . Its i believe it started about two something in the morning and then ran for about 5 hours. So were talking about two hours after the fire started. Yeah. It looks bad. Oh, sure. Thats thats why mr. Mello and the Prosecutors Office have a case. Reporter equally bad for the defense was the evidence that months before the murder tony had tried to get a friend to buy him a magazine for a. 380 handgun. Why do you need to ask a friend in texas for that . Its like its a conversation starter. Hes in texas. A conversation starter . I need a 380 . No, its something else. Like, oh yeah, by the way. Youre in youre from texas. Arent these things a little cheaper over there . It just looks bad that youre asking a friend i understand that. Yeah. For a 380 caliber magazine, and a 380 is used to kill rob cantor. But i didnt kill rob cantor. Did you show sophie a gun . Yeah, i did. Yeah. I s i was holding it for somebody. Reporter according to the defense, the business about the magazine amounted to nothing first, tonys friend never followed through. And second, there was not a shred of evidence that tony was in new jersey on the night rob was killed. How can you prove that a man committed a murder in new jersey when you cannot even prove that he was in new jersey . Reporter in closing, kalish urged the jurors to ignore the prosecutions circumstantial theories and emotional appeals. What we have to do to follow, to follow through on whats right and not what comes out of here, but what comes out of here. Reporter after a trial that lasted two months, the jury spent several days deliberating. For former prosecutor John Molinelli, it was a tense time. Did you worry as the jury was deliberating . They had some questions, they wanted to hear some things again. Did you worry that they couldnt visualize him perhaps in teaneck . I would never admit this while i was the prosecutor, but i can admit it now, yes, i was worried. Reporter on the fourth day of deliberations, the jury sent a message to the judge. Theyd reached a decision. Hds has the jury agreed upon a verdict . Yes, your honor. Is it unanimous . Yes, your honor. Your verdict is . Guilty. Reporter it was an emotional moment of relief for rob cantors widow and daughters. It was a moment that tony tung says he never expected. You hear the word guilty on murder unbelievable. Unbelievable. Reporter though tony never took the stand during his trial, at his sentencing, two months later, he spoke publicly for the first time. Im really for sorry what happened to Robert Cantor and especially to the two daughters of rob. Coming from a father of three daughters, i could tell them that i didnt kill their father. Reporter as expected, no one on the cantor side of the courtroom was buying it. Susan, robs widow, spoke for the family. I think what the defendant leaves is a legacy of darkness and destruction, vengeance and cruelty. Reporter one of robs colleagues also addressed the judge. Please, please, please make sure he never sees the light of a day. Reporter when all was said and done, that is exactly what the judge decided to do. Mr. Tung, if you could please rise. As to count one murder, this Court Sentences you to life imprisonment. The no Early Release act will apply. Reporter tony tung faced his fate alone that day. His daughters, now living in europe with their mother, were not there to say goodbye or shed a tear. But rob cantors daughters were. Tony tung mercilessly executed Robert Cantor and forever changed the lives of so many people. And for that he has to pay a price, which is to say, he has now forfeited his life. And thats justice.
