‘I heard him die': The messages that convicted Michelle Carter

EDITOR'S NOTE: The text messages printed in this story contain graphic language, which some readers may find disturbing.

BOSTON - A woman convicted of manslaughter in her boyfriend’s suicide told her friends she “heard him die,” according to court documents.

That’s part of the evidence Judge Lawrence Moniz used to convict Michelle Carter of involuntary manslaughter in the death of her boyfriend, Conrad Roy III.

Last Friday, Jude Moniz explained his decision to Carter in open court, mentioning a few legal precedents used to hold her responsible for Roy’s death. But it was the evidence contained in text messages between Carter and her friends that he said was what ultimately condemned her, in his opinion.

Two months after Roy died of carbon monoxide poisoning from sitting in his truck with a running motor pump, Carter sent a text message to a friend of hers explaining that she believed herself to be responsible for his death.

“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 fucking told him to get back in,” Carter wrote on Sept. 15, 2014.

Both the prosecuting attorneys and Judge Moniz pointed to that statement as the moment Carter ultimately became responsible for Roy’s death.

As Moniz explained in court Friday, Roy had conducted extensive research on his own, bought the generator and parked his truck. But according to Carter’s text, Roy got out of the truck when he started to sense the carbon monoxide poisoning.

"He literally sought fresh air," Judge Moniz said, referring to Roy's previously unsuccessful attempts to commit suicide. Moniz said Roy had shown a pattern of choosing to live rather than follow through.

If Carter’s text is to be believed, she was on the phone with him when he died, meaning she knew what was happening to him and, in Moniz’s opinion, should have done something to stop him.

“Miss Carter knows – by her own admission – that Mr. Roy has followed her instructions,” Moniz said. “As she indicates in various text messages subsequently created to some of her friends, she indicates that she can hear him coughing and she can hear the loud noise of the motor.”

Moniz explained he couldn’t lean solely on one instance of Carter’s testimony and cited a number of other messages sent to other friends.

“The court notes that I looked for independent corroboration of some of the statements that Miss Carter made to make sure that there was no undue reliance on any one source of evidence,” said Moniz.

In text messages dated around July 12 – the date of Roy’s suicide – Carter tells other friends she spoke with him on the phone and may have known what was going on. Messages between Carter and Roy indicate she indeed knew what he was doing.

“He called me and I heard like muffled sounds and some type of motor running and it was like that for 20 mins and he wouldn't answer. I think he killed himself,” Carter said in a message to a friend.

It was a series of messages like that which Moniz used to convict her of manslaughter -- a decision that has been criticized by free speech advocates.

The ACLU's Massachusetts chapter said in a statement the conviction "exceeds the limits of our criminal laws and violates free speech protections guaranteed by the Massachusetts and U.S. Constitutions."

Legal experts have argued the case could set a precedent in the digital age for holding people responsible for crimes simply by the things they say.

Moniz, however, cited a precedent set in a 2001 case, Commonwealth v Levesque, in which a couple was found responsible for the deaths of six firefighters because they failed to report a fire. When firefighters were told there may be people inside a cold storage warehouse in Worcester, they went inside and were killed in the blaze.

Judge Moniz pointed to Carter’s “failure to act,” alongside her statements urging Roy to follow through with his planned suicide.

Carter is slated to be sentenced on Aug. 3.

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 fucking told him to get back in *** because I knew he would do it all over again the next day and I couldnt have him live the way he was living anymore I couldnt do it I wouldnt let him. And therapy didnt help him and I wanted him to go to McLean with me when I went but he would go in the other department for his issues but he didnt wanna go because he said nothing they would do or say would help him or change the way he feels. So I like started giving up because nothing I did was helping and but I should of tried harder like I should of did more and its all my fault because I could of stopped him but I fucking didnt all I had to say was I love you dont do this one more time and hed still be here and he told me he would give me signs to know he is watching over me but I havent seen any and I just idk I'm sorry about this rant I just needed to get that off my chest and its finally all sinking in

To: 0000000000 Friend #1  7/13/2014 7:01:18 PM(UTC-4) He's dead, he committed suicide
To: 0000000000 Friend #2 7/12/2014 9:24:00 PM(UTC-4) He called me and I heard like muffled sounds and some type of motor running and it was like that for 20 mins and he wouldn't answer. I think he killed himself
From: 0000000000 Friend #2 7/12/2014 9:29:28 PM(UTC-4) I don't think so because he called u Michelle that was his way of not talking but letting you know he's okay
To: 0000000000 Friend #2 7/12/2014 9:31:16 PM(UTC-4) He would of said something tho and I heard like moaning sounds like he was in pain. And I tried calling back and he hasn't answered or anything
To: 0000000000 Friend #2 7/12/2014 9:37:02 PM(UTC-4) He told me that day he went to the store to get a generator for work, I didn't think anything of it at the time but on the phone I heard a motor running which I think was the generator.  I just looked it up online and it said they are dangerous and fatal because they give off carbon monoxide. You can die within 20 mins with that thing, I think he poisioned himself and its all my fault I'm so stupid I should have known that's what he was doing I'm so fucking stupid I don't even know what to do
From: 0000000000 Friend #2 7/12/2014 9:52:16 PM(UTC-4) It's not your fault at all Michelle don't let him make you think that
From: 0000000000 Friend #2 7/12/2014 9:52:21 PM(UTC-4) Think positively
To: 0000000000 Friend #2 7/12/2014 9:57:54 PM(UTC-4) I just feel so helpless right now like his mom isn't answering, he's not answering. I just don't know what to think or do, I can't accept the fact that he may be gone and I could have prevented it
From: 0000000000 Friend #2 7/12/2014 10:23:54 PM(UTC-4) You couldn't have prevented it if it happened Michelle

From: 0000000000 Friend #3 7/20/2014 11:40:07 PM(UTC-4) You're so strong miche you can get thru this
From: 0000000000 Friend #3 7/20/2014 11:40:46 PM(UTC-4) God does everything for a reason. He believes in you or he wouldn't be putting you through all of this. He has a greater plan for you that you just haven't realized yet
To: 0000000000 Friend #3 7/20/2014 11:43:06 PM(UTC-4) That's very wise and so nice of you to say, thank you. I'd like to believe that as well. I just had it all planned out with Conrad. Now I have to do something different, maybe something better, I  just don't think that that's possible. He was my person you know?
From: 0000000000 Friend #3  7/20/2014 11:47:54 PM(UTC-4) I know and you have to remember that we are so young still too. Conrad will always have a special place in your heart. I thought me and brad Harrington were gunna get married one day and look at me now.. With the boy I am POSITIVE will be my husband. Everything will work out Michelle and I am so devastated for you to have lost such a good friend. But he was deeply hurting and there was nothing you could have said or done
To: 0000000000 Friend #3 7/20/2014 11:51:11 PM(UTC-4) Yeah but I had thhe same feeling with Conrad that you have with Brandon. We both knew we were gonna get married, I didn't even have to tell him, he knew. We talked about it and how our life was gonna be in 20 years. And there was many things I could have said and done differently. I'm never gonna forgive myself
From: 0000000000 Friend #3 7/20/2014 11:53:16 PM(UTC-4) Michelle he had a mental illness. There is nothing you could have done. Nothing should ever be so bad that you want to kill is a psychological disorder and nothing you could have said would have changed it. His soul was misguided and he was amazing but there was nothing you could have done
To: 0000000000 Friend #3 7/20/2014 11:59:21 PM(UTC-4) He told me he was gonna do it soon and stuff, I just never believed him because every night when he said he was gonna do it, he didn't. So that night when he actually did it I couldn't believe it. I was talking to him on the phone when he killed himself Liv, I heard him die. I just wish I got him more help, I wish I would of called someone to stop him that night. He would of probably did it a different night but at least I would of got more time with him. At the end of the day, I just really miss him. He was who I talked to until 3 am, and now he's just gone. But his mom called me today, she found a suicide letter he wrote to me. He didn't write one to anyone else. His mom said I was the most important person in his life so to know that just means so much to me 
7/11/2014 11:46:37 PM(UTC-4) To: 00000000000 Friend #4 Do you think he did it?
7/12/2014 1:31:06 PM(UTC-4) To: 00000000000 Friend #4 His mom hasn't answered back yet
7/12/2014 8:02:12 PM(UTC-4) To: 00000000000 Friend #4 Sam 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 mins and that's all I heard
7/12/2014 8:25:34 PM(UTC-4) To: 00000000000 Friend #4 I think he just killed himself
7/12/2014 9:48:14 PM(UTC-4) To: 00000000000 Friend #4 I'm so fucking stupid! The generator he got the other day, I think that was the noise I heard. I just looked it up, they emit carbon monoxide. I think he poisoned himself with it and its all my fault because I should of knew he was gonna do that and I should of stopped him. I keep trying to call and there's no answer. I think he did it. I don't even no what to do right now
