The fate of Michelle Carter rested in the hands of a judge Wednesday after closing arguments were heard in her manslaughter trial. Carter was accused of manslaughter in the death of her boyfriend, Conrad Roy III, after it emerged that she had repeatedly encouraged him to take his own life.

Roy was found inside his truck after having poisoned himself with carbon monoxide in 2014, when he was 18 and Carter was 17.

Carter waived her right to a jury in the trial, leaving the decision in the hands of Bristol County Juvenile Court Judge Lawrence Moniz. In closing arguments Tuesday, both the defense and prosecution laid out their cases to Moniz. For the prosecution, Assistant District Attorney Katie Rayburn cited Carter’s repeated texts to Roy in which she urged him to commit suicide and expressed frustration when he hadn’t done so yet.

“It got to the point where he was apologizing to her,” said Rayburn. “Apologizing for not being dead yet.”

Rayburn also said that although Carter wasn’t physically present at the time of Roy’s death, it didn’t change her direct involvement.

“Back years ago in order to have a relationship you had to actually see somebody – or at a minimum talk on the phone,” said Rayburn. “That is no longer required. People fall in love via the internet and via text. People bully via text and the Internet. You can encourage someone to die via text and you can commit a crime via text.”

For the defense, Carter’s attorney Joseph Cataldo argued Carter had struggles of her own and that she was fighting the side effects of antidepressants at the time.

“He was suicidal in 2011, long before Michelle Carter came along,” said Cataldo. “He was suicidal then. She has some significant issues herself. He’s now bringing her along on this sad journey of his. This was a suicide, not a homicide.”

Also entered into evidence toward the end of the trial were videos recorded on YouTube by Roy in the months before his death. Prosecutors showed the videos in which Roy could be heard discussing his social anxiety and depression, including one taken exactly one month before his suicide.

“I’m looking at myself so negatively,” he said in one of the videos. “I’m looking at myself like a minuscule little particle on the face of this Earth. No good. Trash. Will never be successful. Never have a life. Never have kids. Never learn.”

Roy’s suicide note addressed to Carter was also presented at the trial Tuesday.

“Keep strong in tough times,” the letter read. “You taught me how to be strong and carry on. This life has been too challenging and troublesome to me but I’ll forever be in your heart and we will meet up someday in heaven. Put your best foot forward. You’ll get there. I’m sorry about everything. I am messed up, I guess. I wish I could express my gratitude but I feel brain dead. I love you and greatly appreciate ur effect and kindness towards me. Keep your heart healthy and keep pushing forward.”

Judge Moniz announced the ruling would be made in open court but did not give a specific time for the announcement.
