what are you talking about? i just saw him. >> it just felt like all of the blood just drained right out of your body to hear that kind of news. >> detective scottsdale gordon of the fair haven police department was assigned to the case. his first impression was suicide by carbon monoxide. >> it was apparent that he placed a water pump in the rear of his truck and eventually he passed away as a result of the carbon monoxide from that. >> to those who knew conrad best, it didn't make sense. had they missed something. conrad had been getting help, taking medication and seemed hopeful about his future. his grandmother remembered him using that pump to help out his dad the day before. >> i could still see the smile on his face, the smirky smile. >> and his father recalled them working on a job together a week earlier setting up fireworks on a barge. >> we were laughing and he seemed fine. the last thing i said to him is i love you and he said i love you back. >> so his family wondered what pushed him over the edge. as they struggled with their grief, they got comfort from a surprising source. michelle carter. she reached out to lynn through text messages, consoling her saying conrad loved her very much. >> did you feel like you were getting support or just -- >> oh, absolutely. >> a connection to conrad somehow. >> and i told her i loved her. she told me so many great things about myself that he said. she was just there for me when i needed her. >> conrad's aunts remember getting messages from michelle. >> she sent messages of consolences that she never tried so hard in her life to save someone and she wished that she could have saved him and the at wake she introduced him. >> i was shocked when she said i'm conrad's girlfriend. i had no idea. never heard of her name. >> among conrads things were good-bye letters he had written to different people, like this one to michelle. >> it was very positive. keep doing what you're doing, michelle. he loved the movie "rocky" and gave him a lot of inspiration and i don't know if it is the music or just the mentality of the movie. his dad loved it. and he quoted that to keep moving on and doing great things and -- >> after reading this letter you must have thought conrad and michelle had a special friendship that he wrote her this letter. >> i was very happy that she was in his life. everybody wants to beloved. and especially -- he died so young. i thought she cared about him and loved him. i thanked her for being there for him. >> just weeks after conrad died, michelle contacted his family saying she wanted to raise awareness for suicide prevention. by organizing a baseball tournament. homers for conrad. >> i was thinking, wow, this is impressive. here is a teenager, a high school senior and she's only a month later starting to plan this large fundraiser. >> his whole family showed up. his aunt chrissy was impressed with michelle. then just 17. >> i went up to haer parents at that fundraiser and i said you must be so proud of your daughter. >> back in fair haven, detective gordon was kicking around for answers. hoping to discover why conrad might have taken his own life. >> i just found it odd that an 18-year-old would do it in that manner. >> the detective figured there were clues on conrad's cell phone which was found in his truck and sure enough when he powered it up, he discovered a string of text messages left on the phone from just one person. >> and that michelle carter. >> had deleted all other text conversations with other people. >> correct. >> and when the detectives started reading the texts, he couldn't believe what he was seeing. >> it is one of the things where you just keep reading and it just keeps getting worse and that is what kind of put everything in motion. >> coming up, the text messages no one could fathom. >> i had to read them a couple of times to take it all in. >> words that raised a disturbing question. and was this a suicide or something else?

>> a series of messages that seem to be encouraging him to take his own life. >> encouraging him to take his own life. to the detective, it was unmanageable. he learned michelle and conrad had been texting like teenagers do for almost two years. but a few weeks before his death, something changed. it seemed michelle started a campaign to get conrad to commit suicide. she even gave him suggestions on how to do it. hang yourself, jump off a building, stab yourself, i don't know there is a lot of ways. gordon's partner, detective glenn cudmore also worked the case. >> he was looking at it and it was something to the effect, i can't believe what i'm reading. >> what was she saying. >> you promised me. why haven't you done it yet. >> you disappointed me. >> i'll take care of your family. >> the detectives poured over thousands of text messages and more they read the more disturbed they became. like this em change before conrad died. you can't think about it. you just have to do it. you said you were going to do it. i don't get why you aren't. i don't get it either. so i guess you aren't going to do it then. i'm just confused because you were so ready and determined. conrad wrote back, i'm going to eventually. i don't know what i'm waiting for but i have everything lined up. and this one on the morning of his death. okay, i'm gonna do it today. do you promise? i promise, babe. i have to now. like right now? where do i go? you can't break a promise and just no go in a quiet parking lot or something. >> have you ever seen anything like that in your career as a detective? >> no. >> it was clear to the detectives that conrad had died business his own hand but was what michelle did as crime. they contacted the assistance d.a. >> i want to send you these them. messages if you could look at them and it was shocking. >> the first time you looked at these messages, what is jumping out to you. >> pretty much everything, because everything was focused around you need to do it. why haven't you done it. just get in the car. leave your family. everything will be fine. do, it, do it and badgering. how could anybody be so cruel. >> she checked with her colleague at time and they agreed the text messages warranted further investigation. >> had to read them a couple of times to take it all in. >> does it feel like it wasn't real. >> because you can't imagine that someone would actually send these to someone. >> and of course at that time we didn't know who michelle carter was and the family had never mentioned that name. >> clearly it is black and white that you know this is wrong. but is it black and white, we're going forward with this, this is a crime, i mean i would imagine for you it is complicated. >> yes. it is our duty and responsibility to follow the evidence where it takes us and the evidence was taking us to michelle carter. >> so the commonwealth office told detectives to keep digging and find out more about michelle carter. >> first reaction when you see her picture? >> she's young. she's just a kid. and the words that she was saying in their text messages, it just didn't seem feasible. >> during the investigation, detective cudmore went undercover at that fundraiser homers for conrad he took photos of michelle's every move. to confirm she was the one who sent those texts. he went one step further. he videotaped michelle as he dialed the number he got from conrad's phone. >> you're watching her? >> yes. >> answering the phone? >> yes. >> that is a good sign. >> yes. we had the right person. >> did you just hang up. >> let it stay on on for a few seconds mute the and she hung up the phone. and i said are you sure we have the right girl. she seems to normal. we tend to deal with people it is obvious they may commit crimes and this wasn't the case. she looked totally not the type of person i was expecting to see. >> on the one hand, you have her texting him telling him to take his own life, on the other hand your finding all of this information of her expressing her grief over the death of her friend. >> right. >> it is like two different people. >> exactly. >> yes. >> a few months later, as the investigation continued, detective gordon decided to pay michelle carter a visit. he found her after school and approached her. >> michelle, the reason why we came out here is we're looking into conrad's unfortunate passing. >> and she has no idea she's been watched? >> she has no idea. >> does she look surprised? >> a little bit. but at that point, i don't think she understood really what we had. and where we were going with it. >> at first, michelle told the detective she tried to talk conrad out of suicide. >> how did you help him try and seek that suicide wasn't the right thing. >> well, i told him that i loved him and i told him that a lot of people loved him and how without him nothing would be the same. and what i have personal issues that i got help for and i told him that he should with me and get the help that he needed but he refused. he said that no one would be able to help him and it would make him worse if he got help. >> then, the detective asked her about having contact with conrad on the day he died? >> did you think you had contact with him that day? >> i think so. >> yeah. >> the detective knew that was a lie. >> we have a search warrant for your phone. okay. so we'll be taking it. >> wait, so you're taking my phone? >> yes. >> when we took her phone, i think she started to understand a little bit. that we were looking a little more further into it than she expected. >> he followed her home and said michelle's parents were very cooperative. >> they provided us with everything we needed. and that day we left with her cell phone and her laptop. >> michelle has to know what is going on. but her parents, are they totally in the dark? >> i believe so. absolutely. >> we still believe to this day this they weren't aware of what was going on. >> that would have to be unsettled for the police to come to your house with a search warrant over a suicide that happened months ago. >> absolutely. >> yes. >> did they have more questions? >> i believe they did and i think they were both a little shocked at us being there. >> after going through all of the evidence, including michelle's phone and computer, prosecutors were convinced michelle was criminally responsible for conrad's death. >> words can harm and you don't have the ability to just say your words aren't criminal because they're protected by free speech and there is precedent that have encouraged others to commit suicide have been charged with involuntary manslaughter. >> the charge of involuntary manslaughter, that she could have caused someone's death and she did cause someone's death. >> the prosecution believed that michelle should have known that encouraging him to kill himself could result in him dying. now they have the difficult task of telling conrad's family what they uncovered. >> it was just unbelievable. i think she's holding his head under water. you could tell that he did not want to die. her messages overpowered him. >> i close my eyes and i said, this is not real. how could someone like have an involvement in someone's death and only encouraged it. >> did you just feel like you'd been duped? she's been consoling you this whole time. >> i'm a very forgiving person. and the only thing i could say about the way that she was with me is that she's just really, really not well. >> still, that has to hurt? >> it hurts, yeah. it hurts very much. but i don't dwell on her. i don't think about her. i think about my son. i think about what he would want me to do after his death. how to portray myself. >> the grand jury indicted michelle for involuntary manslaughter and she pleaded not guilty. that is when the world hear the story for the first time and the debate began. was conrad's death a suicide? or a homicide? coming up -- >> why would she do this. >> she wanted the attention. >> a jaw-dropping theory about motive. >> she made sure to instruct him in his last tweet should be to her because she wanted to get a shoutout from him. >> and at trial, michelle makes a stunning decision. >> how are you doing at home -- >> yes. >> is it a choice she'll regret?

detectives poured over thousands of text messages. and they got their answer. >> low and behold on her phone there was text messages to her friends describing what that phone conversation was like. >> the detective said a message michelle sent her friend explained it all. 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. and i told him to get back in. >> and as much as we're in shock about her language prior to that, once we read that, that was really disturbing. >> prosecutor flynn said another text message to that friend made it clear michelle knew what she had done was wrong. >> she said, sam, i just found out from his mother that detectives have some of his things and are going through them to see if anybody texted him or encouraged him. they read my text messages with him and i'm done. his family will hate me and i could go to jail. >> and that is what was at stake on june 5th, 2017. almost three years after conrad roy's death. at the bristol county courthouse, michelle carter went on trial. >> the drama began almost immediately. instead of having the case go before a jury, michelle at the last minute chose to let a judge decide her fate. >> are you doing that of your own free will knowingly and voluntarily? >> yes. >> all right. >> in her hoping statement, flynn drew a straight line from michelle carter as badgering and bullying to conrad in the truck that nice. >> she assist and advised and planned his suicide and reasoned him out of her reservations and told him once he was dead he would be free and happy. >> he kept saying i don't want to do this, this will hurt my family. and she said don't worry about them. all of the fears he brought up, she had a reason to convince him those things weren't real. >> there are people that are going to say everyone is responsible for them themself. he made the decision to that. >> that being said, it is clooer from the text messages, to sam where she told him get back in the car. he didn't want to do it. >> the commonwealth put salmon to read the incriminating message and another one in which michelle described listening to conrad die. >> he just called me and there was a loud noise like a motor and i heard moaning like someone was in pain and he wouldn't answer when i said his name. i stayed on the phone for like 20 minutes and that is all i heard. i think he just killed himself. >> but there was a nagging question. >> why would she do this. >>? because she wanted attention. when her friends were not spending time with her, she would say and do things to try to get their attention. she wanted them to be friends with her. >> it was a shocking theory. prosecutors were basically saying michelle convinced conrad to kill himself so she could be popular. they believed her plan was to get attention by being the grieving girlfriend. they pointed out a text exchange she had with conrad shortly before he died. >> she said am i your girlfriend and he talked about something else. and she goes no, am i your girlfriend, to tell people. and i think she wanted confirmation of the label before he died. >> a day before his death, prosecutors say michelle tested out her plan of being the grieving girlfriend. she texted sam boardman, i'm losing home. >> think he really did it. even show she knew conrad was alive. three minutes later she tested conrad. the generator will work quick and i don't get why you don't use that. >> she's telling her friends that he's missing and she talking to him. >> and then she made sure to instruct him before he did die that he should write her a suicide letter and that his last tweet should be to her because she wanted to give a shutout from him. >> yes. >> the commonwealth alsoed michelle tried to cover her tracks by sending conrad text messages after she knew he was dead. like this one. the day after his suicide. >> did you do something? conrad, i love you so much. please tell me this is a joke. and she continued sending texts to his phone for months. nearly 80 of them. the prosecution argued she deliberately sent the texts as a way to change her story. >> at the time i went along with it because i knew you weren't going to do anything but you did it and i'm so sorry i didn't save it you. >> it was agonizing to sit in the courtroom and hear the new details. >> it was pretty shocking. a lot of times it doesn't seem real. >> do you believe in your heart that it was criminal, what she did?

like i think i'm going away to a place for my eating disorder so help me over come it and stuff. where are you going? it is called mcclain hospital in belmont, mass. i think it would be so good for you and we could get through our issues together. >> michelle carter was trying to talk him out of it. go to mcclain hospital. they will help you. she nothing but resistance from conrad roy. >> one of the main points of your argument was that conrad roy had tried this before and researched various ways to take his own life and this was not something created by michelle carter. >> right. the nature of their relationship was always in the background suicidal thinking on conrad roy's part. so that is clear as day in the texting relationship that anybody could see when you go back and examine the record. michelle for a year and a half always tried to% wa -- to persu him not to commit suicide and he rejected her thoughts of staying alive. it wasn't until the last two weeks of his life while michelle finally endorsed his plan. >> i think that is where people have the biggest problem with this case is why. why would she encourage him and she's supposed to be his friend. >> she came to the realization that he didn't want to live any more and he would only hate her. his words, i will only hate you if you tell somebody about my plan. she was somebody who was under the influence of his suicidal thinking. >> why not reach out to his parents and say, there is a problem here. >> this was a plan between this 18-year-old and this 17-year-old who was convinced by him not to tell anyone. now i think she only met his mother one time. i don't think she ever met the father. you're asking a 17-year-old girl to reach out to parents she doesn't know. that is just not realistic the way teenagers think. >> while the prosecution presented michelle carter as an attention seeker, the defense portrayed her as a victim taking antidepressants and was non no shape to help a suicidal friend. >> the facts will show that michelle carter is going through her own struggles. >> he was bombarded by his suicide thinking so you take that and then you mix in her own issues that she was struggling with, eating disorder and then eventually being diagnosed with a major depressive disorder herself. >> the defense called an expert witness. psychiatrist dr. peter breggan to the stand. he testified the anti-depressants impaired her judgment. >> she was immeshed in a delusion system. >> in a what. >> in a delusion where she's thinking that it is a good thing to help him die. >> baggan testified that he believed that conrad was in control of the relationship. and that he used the vul ferable and depressed michelle to help him commit suicide. >> he was constantly telling michelle and not his other friends, will you help me. >> the biggest hurdle for the defense it seemed was michelle's admission of guilt to her friend sam. >> if you actually read the entire statement that she texted, she said it is my fault, i told him to get back in. but then it continues to say, but i didn't think he was going to ultimately do it. i want him to get help. i feel so badly about this. >> but an one hand you're saying she didn't think he was going to get back him and get him help but then on the other hand you're though, you're saying she was kind of had sort of succumb to okay, i'm going to help him. he should do it if he wants to do it that badly which. >> she was all over the place. she was both. so you're dealing with a teenager who really does not understand exactly what is going on over on conrad roy's side. she's 40 miles away not present. only conrad row really knows why he took his own life. >> as for michelle's alleged motive she was an attention seeker. the prosecution got it all wrong. >> it was a fabricated motive. they wanted to create a motive because they couldn't take the true motive that she was suffering herself and was convinced by conrad roy to endorse his plan because that's what happened. >> does michelle know how bad she looks to people who don't know this side of the story or who are not seeing it this way?
