Carter's lawyer now trying to get statements she made to cops thrown out

But prosecution said Carter engaged in a 'systematic campaign of coercion' that targeted Roy's insecurities

Her attorneys had argued the texts were free speech protected by the First Amendment and didn't cause Roy to kill himself

Michelle Carter, then 17, sent Conrad Roy III, 18, text messages instructing and encouraging him to take his own life in 2014, prosecutors say

A teenage girl who sent her boyfriend text messages encouraging him to kill himself asked a judge Friday to keep statements she made to police out of her involuntary manslaughter trial.

The request was among almost two dozen motions filed by lawyers for Michelle Carter, now 19, in Taunton Juvenile Court, The Boston Globe reported.

The Plainville woman is charged with involuntary manslaughter in the 2014 death of 18-year-old Conrad Roy III, of Mattapoisett.

A woman who sent her boyfriend text messages encouraging him to kill himself asked a judge Friday to keep statements she made to police out of her involuntary manslaughter trial.

At the hearing, the judge did not rule on the motions but said the trial could start in December. He plans to hear the motion to suppress Carter's interview on October 14.

Roy's body was found in his pickup in Fairhaven on July 13, 2014. He died of carbon monoxide poisoning and police found a gasoline-operated water pump in the back seat. Prosecutors say Carter and Roy communicated as he sat in the truck.

'I thought you wanted to do this. The time is right and you're ready, you just need to do it!' Carter wrote in one message.

Carter's lawyer, Joseph Cataldo, has said that the texts are protected free speech and that Roy was depressed and had previously tried to take his own life.

The state's highest court ruled earlier this month that a grand jury had probable cause to indict Carter based on evidence suggesting she engaged in a 'systematic campaign of coercion.'

Carter was 17 at the time, but is charged as a youthful offender, making her subject to adult sentences.

Carter's lawyer had argued that her texts were free speech protected by the First Amendment and didn't cause Roy to kill himself.

But the court said Carter engaged in a 'systematic campaign of coercion' that targeted Roy's insecurities and that her instruction to 'get back in' his truck in the final moments of his life was a 'direct, causal link' to his death.

'In sum, we conclude that there was probable cause to show that the coercive quality of the defendant's verbal conduct overwhelmed whatever willpower the eighteen year old victim had to cope with his depression, and that but for the defendant's admonishments, pressure, and instructions, the victim would not have gotten back into the truck and poisoned himself to death,' Justice Robert Cordy wrote for the court in the unanimous ruling.

The case drew national attention after transcripts of text messages Carter sent to Roy according to the indictment were released publicly, showing her urging him to follow through on his plan to kill himself and chastising him when he expressed doubts.

'I thought you wanted to do this. The time is right and you're ready, you just need to do it!' Carter wrote in one message according to prosecutors.

'You can't think about it. You just have to do it. You said you were gonna do it. Like I don't get why you aren't,' authorities say she wrote in another message.

Carter and Roy had met in Florida two years earlier while visiting relatives. Their relationship largely consisted of text messages and emails. They hadn't seen each other in more than a year when Roy died, even though they lived only about 50 miles apart in Massachusetts, Carter in Plainville, and Roy in Mattapoisett.

Roy's grandmother Janice Roy said the family is happy Carter can be put on trial.

'He was very vulnerable at that stage,' she said.

'IT'S NOW OR NEVER': MICHELLE CARTER'S MESSAGES TO CONRAD ROY Prosecutors say Michelle Carter sent her boyfriend, Conrad Roy III, dozens of text messages urging him to take his own life. Carter's lawyer argues that she tried repeatedly to talk him out of it and only began to support the plan when it became clear he would not change his mind. Here are excerpts from their text exchanges, with messages cited by her lawyer first, followed by those cited by prosecutors: June 29, 2014: Carter: 'But the mental hospital would help you. I know you don't think it would but I'm telling you, if you give them a chance, they can save your life' Carter: 'Part of me wants you to try something and fail just so you can get help' Roy: 'It doesn't help. trust me' Carter: 'So what are you gonna do then? Keep being all talk and no action and everyday go thru saying how badly you wanna kill yourself? Or are you gonna try to get better?' Roy: 'I can't get better I already made my decision.' July 7, 2014: Roy: 'if you were in my position. honestly what would you do' Carter: 'I would get help. That's just me tho. When I have a serious problem like that, my first instinct is to get help because I know I can't do it on my own' Roy: 'Well it's too late I already gave up.' Between July 6, 2014 and July 12, 2014: Carter: 'Always smile, and yeah, you have to just do it. You have everything you need. There is no way you can fail. Tonight is the night. It's now or never.' Carter: '(D)on't be scared. You already made this decision and if you don't do it tonight you're gonna be thinking about it all the time and stuff all the rest of your life and be miserable. You're finally going to be happy in heaven. No more pain. No more bad thoughts and worries. You'll be free.' Carter: 'I just want to make sure you're being serious. Like I know you are, but I don't know. You always say you're gonna do it, but you never do. I just want to make sure tonight is the real thing.' Carter: 'When are you gonna do it? Stop ignoring the question' Carter: 'You can't keep living this way. You just need to do it like you did the last time and not think about it and just do it, babe. You can't keep doing this every day. Roy: 'I do want to but I'm like freaking for my family I guess. I don't know.' Carter: 'Conrad, I told you I'll take care of them. Everyone will take care of them to make sure they won't be alone and people will help them get through it. We talked about this and they will be okay and accept it. People who commit suicide don't think this much. They just could do it.' Advertisement

Carter's lawyer, Joseph Cataldo, argued that Roy was a depressed teenager who had previously tried to take his own life and was determined to finish the job this time. He also argued that Carter shouldn't have been charged with manslaughter because Massachusetts doesn't have a law against encouraging or assisting suicide.

Cataldo said earlier in July that he was surprised and disappointed by the court's ruling. But he noted that the court didn't weigh in on Carter's guilt or innocence, but merely found there was enough evidence for the case to proceed to trial.

'At trial, it's proof beyond a reasonable doubt, which is a much higher standard, and I'm confident that ultimately, after trial, Michelle Carter will be acquitted,' he said.

In addition to the text messages, prosecutors focused on a phone conversation Carter had with Roy while he was in his truck inhaling carbon monoxide fumes. Prosecutors said Carter sent a text to one of her friends after Roy's death and told her that while she was on the phone with Roy, he got out of his truck because he became frightened. She said she told him to 'get back in'.
