His grieving aunt speaking out to 20 20. How do you even wrap your mind around that . He was a kid. He was ours. He was our kid. The private video diaries. I feel, whats the word recorded just weeks before his death. Im definitely wired from everyone else, like theres something wrong with me. Her secret cell phone Text Messages, goading him on. Okay, so you want to kill yourself . When are you going to do it . That doesnt make her behavior okay or good. But the question is, is it criminal . You said you dont want to take your life. You dont want to. She said this to him for two years. Until she eventually says do it. Can words kill . Good evening. Welcome to 20 20 saturday. Im elizabeth vargas. And im david muir. This question tonight can words kill . That was the question at the heart of a courtroom drama that captivated the country in the socalled suicide texter case. Two sets of parents stunned as they saw what their kids were doing and saying on their cell phones. All culminating in a groundbreaking conviction, which essentially concluded that Text Messages and phone cats can lead to suicide. Words can indeed kill. But was that the motive . Deborah roberts has that tragic teenage love story with a very modern twist. Buzz answereds bay on the south coast of massachusetts. Good sailing weather. Striped bass are biting. And in matapoisett, the views from the historic light at whales point built to guide ships to safe harbor as spectacular as ever. Its the kind of summer conrad roy would have loved. Conr conrads aunt kim. Tell us about him as he was growing up. He was kind of like the instigator in our family. Hes the kid that never got in trouble. Hed start the trouble but he somehow got away with it. Reporter athletic . Oh, yeah. He played baseball. He loved baseball. Reporter conrad, whose family calls him coco, excels, at least academically, in high school. He graduates in 2014 with good grades and test scores high enough to win him a free ride at a state college, but hes unsure whether to go off to school or join the family tugboat business. And did conrad like it . Yeah. He loved it. He loved being on the water. He got his captains license at the age of 18 which is pretty awesome. Reporter a life by the sea, with so much promise. But conrad is adrift. Hi, this is Conrad Henry Roy iii, reporting to you about whats going on through my mind, whats going on through my head the last few days. Reporter confiding deep Emotional Distress in private video diaries. Ive created a monster out of myself the past few years. Because of my depression. Racing thoughts. Suicidal thoughts. It is a hard video to watch. I think we see a very troubled teenager whos obviously going through a multitude of emotions and issues. The hardest thing for me is to be comfortable in my own skin. Reporter after his parents divorce in 2011, he begins a downward spiral. Depression, a stay in a psychiatric facility, and several attempts at suicide. I feel whats the word . I feel like im differently wired from everyone else. Reporter but this story really begins with his chance encounter with a girl. Conrad meets Michelle Carter while both are visiting relatives in florida. Shes a year younger and lives in plainville, an hour north of conrads hometown. Like conrad, shes athletic, a softball player. Coach ed mcfarland says she was a decent shortstop, and a nice girl. Quiet kid, never known her to do a mean thing. Would do whatever she could to help you in the process. Reporter classmates would later vote michelle most likely to brighten your day. But sera congi, a reporter for abc boston affiliate wcvb, says michelle was also struggling. She suffered from depression, and she had an eating disorder. We know she took antidepressants. Reporter something that seemed to bother michelle most making and keeping friends. But michelles new friend conrad apparently fills the void. They fall into an intense facebook, texting, all hours of the day and night, on again, off again, virtual romance. One even conrads mother knew very little about. Does she know who she is . She just thought she was an acquaintance of conrads, nothing more. Reporter in fact, we cant find a single photo of the teens together. They meet in person only two or three times, the relationship almost entirely electronic. They were intimate with each other over text message, because they talked so much about their personal feelings. But were they a traditional boyfriend and girlfriend . Its hard to say. Reporter but the relationship is clearly intense. Conrad sends michelle this selfie. If you only knew whats inside my head. Reporter in a facebook exchange, early on, conrad tells michelle about his brush with death. I tried to kill myself. How did you try to kill yourself . Do you still want to . No, im going to. Just letting you know. The voices in my head tell me to. Reporter later, he confides hes planning to try again. I want to die. I know you want to and you research it and everything, but are you actually really gonna do it . Yeah. If i can find a way to 100 work. He tells her pretty definitively early on that he wants to die, and that he has a plan to die, and that hes going to do it. Reporter by the summer of 2014, conrad on his own combs the internet hundreds of times, searching terms such as cyanide, death by cop, and easy ways to find poisons. He sends michelle a photo of a rifle, and a noose hanging from a tree. Then conrad hints they should do something together. We should be like romeo and juliet at the end. Ha ha, id love to be your juliet. But do you know what happens at the end . Oh, yeah, [ bleep ] no we are not dying. Reporter dan glaun is a reporter for mass live, a digital news outlet. Theres these weeks and weeks of messages where conrad roy is saying, im depressed. I want to die. He says this to her over and over. Shes overwhelmed by this caretaker role she has with her boyfriend. She cant handle it. Reporter michelle, also emotionally fragile, repeatedly tries to talk him out of it. Conrad, stop. Youre not gonna do it. I know you wont. I dont want you to. No, i actually am. You have so much to live for. Please dont. Reporter for two years the relationship builds, the starcrossed teens discussing all kinds of things online. But conrads obsession with suicide runs through it like a sinister thread, and for most of that time, michelle consistently encouraging him to get help. Im never gonna be better. I have to accept that. Youre in a dark tunnel but its not gonna last forever. Youll find the light someday. Shes encouraging him to stay alive, shes trying to pull him away from that darkness. Reporter when shes hospitalized for an eating disorder, she asks conrad to join her. You arent gonna get better on your own, you need professional help like me, people who know how to treat it and fix it. Reporter conrad warns michelle not to tell anyone who could stop him and she doesnt. And the only way id hate you is if you told people about this. You hear me . Im not gonna tell anyone. Because if i did then youd have to go to a hospital and i know thats not what you want. Reporter on the fourth of july, 2014, conrad is talking more and more about ending his life. I wish i had a gun. Would you use it . Yes. Reporter his family says they know nothing about these messages, and think hes feeling better emotionally. The morning of july 12th seems to begin as a typical summer day for conrad roy. He goes to Horseneck Beach with his mom and younger sisters. They walk on the beach, and his mother talks about how he seemed more optimistic. She kind of felt a little more encouraged that maybe he was moving forward and that it was a good day. Reporter ominously, though, instead of swimming or sunbathing, conrad spends most of the afternoon in the car, feverishly texting with someone. That evening, conrad tells his mom hes going to see a friend. His mother asks, will you be home for dinner . And he says he doesnt know, he doesnt think so. And thats the last thing he says to his mother. Reporter her son drives off in his black pickup truck, and disappears into the summer night. And that was the last time anyone in his family saw him alive. Reporter when we come back, searching for conrad, and the haunting messages on his cell phone that will shatter two families.

He had driven off from his mothers house in fairhaven, massachusetts, on a saturday evening, supposedly to visit a friend. But by sunday morning he still wasnt home. You could tell she was worried. And i said, well, you really need to call the authorities and see if they can start searching for him. Reporter with no word from her son, a frantic lynn roy contacted the Fairhaven Police department. An officer was soon on the case and began searching. He wound up in this kmart parking lot. And i saw out of the corner of my eye, a black f250 parked over there. Reporter parked right over here. Right over there. Reporter fairhaven officer dave correia finds the black pickup truck, conrads lifeless body behind the wheel. Hes gone. His life over at age 18. Id seen enough people that were gone to realize just by looking at him that he was gone, that there was nothing that anybody was going to be able to do for him. Reporter in the back seat, this portable water pump, powered by a gasoline engine. Running that engine with the windows closed filled the truck with a lethal cloud of Carbon Monoxide gas, enough to kill anyone inside in 20 minutes flat. Deadly as a loaded gun. Its immediately clear that its a suicide. They contact his parents and lynn roy learns that her son has died. And i just grabbed my sister and hugged her as tight as i could, and she reporter how did you even wrap your mind around that . You cant. Theres no way. He was a kid. He was ours. He was our kid. Reporter conrad had left notes at home for his family, and Michelle Carter. He thanks her for being there for him, for supporting him, for sticking with him as he went through all of these struggles and Mental Health problems. Reporter immediately conrads grieving family is comforted by a friend of his they had scarcely known existed michelle. She begins trying to establish a relationship with conrad roys family. With his mother, lynn, and his younger sister, camdyn, telling them that conrad would have wanted them to stay strong and to not break down over him. Reporter she begins texting, calling, emailing. I am so sorry i didnt do enough to save him. I have never tried harder in my life to help fix someone. Reporter michelle, who most of conrads family and friends had never met, also attends his wake and his funeral. And Michelle Carter was showing up at these various times. Yeah. Reporter and even asked for part of his ashes . Yeah, yeah. She wanted to go through his room and take some of his belongings. Reporter what did you all make of that . Thats when things started to get a little weird. It was like, hmm. Yeah, you dont do that. One thing that she does, is she begins organizing a Charity Baseball tournament for conrad. Reporter on a Facebook Page she says she wants to be an antisuicide activist. Even though i could not save my boyfriends life, i want to put myself out there to try to save as many other lives as possible. Reporter and Something Else a little spooky. Even after his death, michelle continues texting conrad. Today it has been one month since you passed. It was a hard day for all of us. I hope you were looking down with a smile. Reporter meantime, Fairhaven Police are working what seems to be an open and shutcase of teen suicide. Until a detective thinks to check conrads cell phone. I got the call the next day from detective gordon, he wanted to know where the phone was. He had gotten the code from the family. I told him where it was, and of course the rest is history. Reporter on that phone, some very strange Text Messages with Michelle Carter. I dont get why you dont just overdose again, but go somewhere in private. You already know it works. She actually begins to almost agree with him. Like, okay, so you want to kill yourself . When are you going to do it . How are you going to do it . Youre really gonna do this . Yeah. Okay, theres no turning back now. Starting about on july 2nd she starts saying, are you serious . Like, you should just do it. Reporter in early july, after conrad apparently fails to go through with an overdose of sleeping pills, police say michelle seems not relieved, but irritated. I knew you werent gonna try hard. I feel like such an idiot. Why . Because you didnt even do anything and i poured my heart out to you thinking this was gonna be the last time i talked to you. I thought you really wanted to die, but apparently you dont. I feel played and just stupid. Shes almost bullying him about it. Tonight . Eventually. See, thats what i mean. You keep pushing it off reporter authorities are stunned to find that in the last week of his life, michelle asks conrad when he was going to kill himself more than 40 times. When are you gonna do it . Ill let you know when. Well, is it gonna be soon . Whenever he had doubts, shed diminish them. Whenever he had guilt about leaving his family, she assured him that she would comfort them. Everyone will be sad for a while, but they will get over it and move on. Reporter still ahead were talking to Michelle Carter. Reporter detectives go to school. Michelle carters school. Michelle, the reason we came out here is because we were looking into conrads unfortunate passing. Reporter how will the senior most likely to brighten your day explain all those Text Messages .

Reporter it seems everyones talking about teen suicide. The Tony Award Winning musical, dear evan hansen, taking on that difficult subject. Can anybody see is anybody waiting is anybody waiting reporter from broadway to netflix, and the tv show 13 reasons why, about a teenage girl who takes her life. Im about to tell you the story of my life. More specifically, why my life ended. And if youre listening to this tape, youre one of the reasons why. Reporter but for conrad roy, the angst was not entertainment, it was all too real. Hi. This is conrad roy, and im going to talk to you about social anxiety. Reporter the 18yearold documents his despair in secret video diaries just weeks before his death. What i am doing is im looking at myself so negatively. Im looking at myself, minuscule little particle on the face of this earth thats no good, trash, will never be successful. Never have a wife, never have kids, never learn. Reporter now Police Investigating his suicide are searching through his phone and all his electronic exchanges with Michelle Carter. Theyre beginning to suspect her role in his death was not as innocent as it first appeared. Mostly because of messages like this one. Hanging is painless and takes like a second if you do it right. Reporter michelle, police say, is actively helping conrad plan his death. Carbon monoxide poisoning is the best option. If you fall asleep in your car while its running in a garage, it will kill you and theres no pain. Portable generator thats it. Do you have one of those . Theres one at work. I was thinking turning it on in my truck and passing out asleep youre a genius. He gets a gas generator but it breaks down. Go to sears. Google it, hold on, ill do it for you, and ill tell you exactly how to kill yourself hopefully. Reporter instead, conrad takes a gas powered water pump from a relative. But as with previous attempts, he seems to waver. Im scared babe. Its okay to be scared and its normal. I mean, youre about to die. Reporter but the next morning, conrad, as authorities will later put it, has the audacity to still be alive. Hike why am i so hesitant lately . Youre so hesitant because you keep overthinking it and pushing it off. You just need to do it conrad. Its time to do it today. Reporter that evening, conrad still procrastinating, michelle still pushing. Are you going to do it now . Leaving now. Okay, you can do this. Reporter five minutes later, conrad fires off another text. Okay, im almost there. That last text message is before he drives to the kmart parking lot where he turns the water pump on, in the cabin of his truck. And then hes gone. Reporter months after conrads death, a detective goes to king phillip high school, to have a talk with Michelle Carter. We were talking, and then the phone hung up but i didnt really think anything of it. Reporter didnt think anything of it, she tells police, but thats not what she told her friends. A search of her phone reveals michelle sent a series of stunning Text Messages to classmate, samantha boardman, after conrads death. When michelle hears detectives are searching conrads phone, she sends samantha a frantic message. Sam, they read my messages with him, im done. His family will hate me and i could go to jail. Reporter but it gets worse. Two months after conrads death, michelle sends samantha this jawdropping admission. Sam, his death is my fault. Like honestly, i could have stopped him. I was on the phone with him and he got out of the car because it was working and he got scared [ bleep ] and i told him to get back in. When he got out of the truck and said, i cant do this. Im not gonna do this, she said, get back in the truck. Suck it up. That is the saddest part of this whole story, the truck is filling up with Carbon Monoxide, and he gets out. And she tells her friend sam that she told conrad to get back in the truck. She did not call police. She did not call her parents, his parents, nobody. She sat there, waited for him to die and then texted her friends, omg, i think my friend just committed suicide. Reporter michelle goes on to tell samantha i couldnt have him live the way he was living anymore. I couldnt do it. I wouldnt let him. I could of stopped him but i [ bleep ] didnt. Reporter we asked former prosecutor nancy grace and abc chief legal analyst dan abrams to discuss the case. Is the question whether words can kill . Is that what it is . Oh, this was more than words. Much more than words. She researched modes of death. She said, you could hang yourself. You could put a plastic bag over your head. You could shoot yourself in the head. And the reason that she did that is because he asked her for help. Hes the one who drew her into this thing from the beginning. Reporter how would you describe this relationship between these two young people . Tragic. Thats how i would describe it. It was conrad roy laying a lot of his baggage on Michelle Carter, he consistently bombarded her with his suicidal thinking. I dont think that she helped him kill himself. I think she forced him to kill himself. Reporter you think she is the cause of his death . Mmhmm. Yeah. I think if it wasnt for her, hed still be here. Reporter the Text Messages may sound horrible, but are they a crime . Prosecutors say yes. And six months after conrad roys death, a grand jury agrees that Michelle Carters words are a weapon. Indicting her on a charge of Involuntary Manslaughter. That trial making national headlines. The teenage girl is facing charges in another teens suicide. The young woman is now charged with manslaughter after her then boyfriend killed himself. We had never heard of a story like that before, a charge like that before, a case like that before. Whats novel about it is the technology that we dont have to be at the crime scene, that we can still be present when somebodys committing a crime because were on the phone with them, were talking to them, were in their head. She was virtually present. Reporter the trial, up next. And look who takes the stand. Michelle carter, but not for the reason you might think. Stay with us. We can now simulate the exact anatomyh care, of a patients brain before surgery. If we can do that, imagine what we can do for seizures. And if we can fix damaged heart valves without open heart surgery, imagine what we can do for an irregular heartbeat, even high blood pressure. If we can use analyze each patients Breast Cancer to personalize their treatment, imagine what we can do for the conditions that affect us all. Imagine what we can do for you. We return now to a pretty shocking story playing out in court right now. She faces up to 20 years if convicted. Prosecutors say because of what was written in those texts. Reporter the case some are calling death by text captures the full attention of the country. The defense claims that roy had planned that suicide and that carters words did not alter his plans. Reporter Michelle Carter, charged with Involuntary Manslaughter for allegedly causing the death of conrad roy, a boyfriend she had only seen in person three times. Its a controversial accusation. This is new legal territory. This was potentially precedent setting in the state of massachusetts. That someone could be held accountable for Involuntary Manslaughter based on their words. Or in this case, their texts. Reporter can you be responsible for killing someone from miles away, with words alone . What she said is reprehensible and it is just bonechilling. But thats a separate question from, is it criminal . Reporter on the day of jury selection in Michelle Carters manslaughter trial in taunton, massachusetts, the case takes a whiplash turn. Today was supposed to be the day that they would begin the process of selecting 16 jurors for this trial, but in a relatively surprise move, first thing this morning Michelle Carter chooses not to have a jury decide her fate. Has anyone promised you anything or threatened you in any way to make you forego your right to a jury trial . No. Reporter carter puts her fate in the hands of one man, judge Lawrence Moniz. Mistake . Big mistake. Reporter what might the defense have hoped to gain by going for a bench trial . I think the defense was afraid of the response that a jury would have to these texts. Theyre terrible. Theyre very incendiary. And so i think that you are hoping that a judge will be able to view it in a more rational like calmer heads prevail. And maybe focus on issues like causation and the definition of the statute, as opposed to how horrible the texts are. Reporter and so the trial begins. She assisted and devised and advised and planned his suicide. She pushed him to kill himself sooner rather than later, and she mocked him when he chose to delay his death. Reporter prosecutors Mary Clare Flynn and Katie Rayburn laying out the case and a motive. If you really look at it, your honor, shes really desperate for attention. Look at me, i lost my boyfriend. You presented her as a girl who was manipulating, who was looking for attention. She wanted him to die. It appears to gain attention or to gain friendships or get girls to like her more. She used him as a pawn in her sick game. Reporter the prosecutions first witness, conrads mom, lynn roy. So you said that you brought him to either a hospital in october of 2012 . October 3rd. And what was the reason for that . Because he was having suicidal thoughts. Reporter prosecutors call 14 witnesses. The officer who found conrad in the parking lot appears to be mr. Conrad roy. Reporter the medical examiner who determined it was Carbon Monoxide that killed him. And most important, Michelle Carters classmates, those girls she so desperately wanted to befriend. 8 25, does Michelle Carter now send you another text that you receive later on that night . Yes. And what does she tell you . I think he just killed himself. Reporter she testifies about that incriminating text from michelle. I was on the phone with him and he got out of the car because it was working and he got scared. And i [ bleep ] told him to get back in. Reporter isnt that pretty incriminating stuff . Yeah. Yes. And she goes on to say, i could have called police. I could have called his family. But she didnt. What she did do with him, three minutes, is start texting the guy she was trying to date and her other friend, sam boardman, and talking to them about, oh, its all about me, what am i going to do now . She essentially put him back into a gas chamber, she listened to him gasp for air, take his last breath, and die, and she did nothing. Reporter michelles defense resting nearly entirely on one witness, psychiatrist peter breggin. How could the girl whos most likely to brighten your day encourage her boyfriend to take his life . The short explanation is, she thought that was the only way to help him. She had had a drastic change in medication three months earlier. Reporter dr. Breggin testifies michelle was under the influence of involuntary intoxication caused by her antidepressants and she was overwhelmed by what he calls conrads abusive talk of suicide. She didnt want him to take his life. She said, you dont want to take your life. You dont want to. She said this to him for two years. Reporter until she eventually says, do it. She said if thats what you want, do it. She breaks. She breaks under his pressure, under the drugs. Reporter what did you make of the psychiatrist saying that she was involuntarily intoxicated. I couldnt believe that they even tried that. Reporter but shes a teenager, shes got emotional troubles and shes taking medication. Yes, shes evil. That is her trouble. Reporter what doesnt the world understand about Michelle Carter . That she loved conrad roy. She really cared for conrad roy. She thought she was supporting what he wanted. And she even talks about it in her texting. Youre going to go to heaven, as he talked about. Youre gonna be a great angel. Reporter after six days of testimony, the fastmoving trial wraps up with closing arguments. Its a new day and age, your honor, and the phones that we have now allow you to be virtually present with somebody. People fall in love on the internet and via text, people bully via text and the internet, and you can encourage someone to die via text, and you can commit a crime via text. You can look at the various Text Messages, as well as the psychological records. You will see that mr. Roy himself stated to Michelle Carter, i want to die. Straight up, those words. I want to die. This is not a homicide. Michelle carter did not kill conrad roy. Its sad. Its tragic, but its just not a homicide. She absolutely knew it was wrong, and she absolutely caused the death of this 18yearold boy. And i ask you to find her guilty. Ms. Carter, please stand. Reporter the judges verdict. Where will Michelle Carter spend the best years of her life . When we come back. I think a lot of people were a little surprised that thats what actually happened. Reporter stay with us. The gigspeed network that powers the dreams of americas businesses is now doing the same for americas olympic and paralympic athletes. Dream gig. Comcast business. June 16th, 2017. Decision day at the usually quiet courthouse in Historic Downtown taunton, massachusetts. The press out in full force, anticipating judgment day for Michelle Carter. She strides into court escorted by Court Officers and her defense team. Then upstairs to hear the judges decision on whether she caused the death by suicide of boyfriend conrad roy. It was a packed courtroom and many relatives of conrad roy were filling the first couple of rows. Reporter more than a half dozen whiteshirted Court Officers stand guard near the carter and roy families. The right side, the first few rows, filled with conrad roys relatives. The left side, Michelle Carters parents. Reporter judge Lawrence Moniz is ready to deliver a verdict in the Involuntary Manslaughter trial of Michelle Carter. Shes opted against a jury. We obviously expect him to say guilty or not guilty, but he chooses to give an explanation to his verdict. To provide some context for the decisions that have been made. Reporter as the judge begins to read, michelle appears shaken, displaying the most emotion shes shown during the entire trial, her attorney taking her hand. This court first finds that the actions taken by miss carter are you going to do it tonight . Constituted wanton and reckless conduct by her. The commonwealth has not proven that said behavior caused the death of mr. Roy. Reporter hearing that, michelle lets out a sob. He starts off by saying that it was not reasonable behavior. But that didnt make him kill himself. Reporter conrads aunt kim bozzi sits in the tense courtroom. So when judge moniz starts offering his verdict, it sounds at one point that maybe shes going to be acquitted. Yeah, i was kind of like a roller coaster of emotions. All i could think about was conrad and how she has to be held accountable. She has to be. Theres no way we went through all of this. You know . I thought it was going very well. It sounded like he was going to acquit her. Reporter but the judge goes on. However, his court finds that instructing mr. Roy to get back in the truck constituted wanton and reckless conduct by miss carter, creating a situation where there is a high degree of likelihood that substantial harm would result to mr. Roy. If the judge had written this for maximum dramatic tension, i dont think he couldve done a better job. For 15 minutes, this courtroom was dead silent. I could hear my pen scratching on my notepad when i was taking notes. She called no one. And finally, she did not issue a simple additional instruction, get out of the truck. Ms. Carter, please stand. This court, having reviewed the evidence and applied the law thereto, now finds you guilty. Reporter Michelle Carter, now 20 years old, guilty of Involuntary Manslaughter. When you heard guilty . Oh, my god. Three years of going through this. I felt good. I know that may seem odd, and i know its a situation where there are no winners, but i felt like we won. The fact that we got a guilty conviction was a victory. The world would know that conrad roy did not commit suicide, that he was a victim of a homicide. I was very surprised. I support the judges decision, but i really did not think the judge would have the backbone to do it. And he did. Reporter do you regret not seating a jury . If i had to do it over again, i might pick 12 people in the box. Reporter outside, the media pouring out of the courthouse. Out of the way, guys. Reporter defense Attorney Joseph Cataldo runs a gauntlet of cameras and microphones. Im very disappointed with the outcome, with the verdict. Reporter conrad roys father speaking to reporters after the verdict. This has been a very tough time for our family and we would like to just process this verdict that were happy with. Reporter prosecutor Katie Rayburn reminds everyone that, in the end, this case was about an 18yearold boy, conrad roy. I know we all wish he had the opportunity to grow up, into adulthood, to become a tugboat captain and to enjoy his future. Reporter as she speaks, conrads father overcome with emotion. Given the nature of this case, i would like to conclude by reminding everyone that if you have a loved one in need, or you know someone in need of help please tell someone. Reporter a court has decided that words can kill. Are you going to do it now . Yes, she was guilty of Involuntary Manslaughter, but does she deserve to be in jail .

Reporter the courthouse in taunton, massachusetts, where Michelle Carters future will be decided is a modern building. A fitting location for this most modern of crimes.
