Carter's defense attorney, Joseph Cataldo, told Taunton Juvenile Court Judge Lawrence Moniz that a March date is too soon and that he needs until April or May to properly prepare, the Boston Herald reported.

'Oh, that's not happening. That's not happening,' Moniz said in a hearing on Monday.

'We're not going to put it out that far.'

During the pretrial hearing Monday, the judge granted a request from Carter's lawyer for funds to hire an expert to examine an antidepressant both Carter and Roy were taking at the time of his death.

The judge initially rejected the request earlier this month.

But Carter's attorney said the drug Celexa could be a key to Carter's defense because it can increase suicidal thoughts.

Moniz reversed himself after Cataldo offered more information on the drug.

'I think it's relevant, but it will be up to the judge to determine whether a jury should know about that,' Cataldo told the Herald.

Cataldo also wants to look at evidence of domestic abuse within Roy's family.

'I told him a lot of people loved him ... I told him he should come with me and get the help he needed.'

'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
