Commonwealth v. Michelle Carter is the 2017 Massachusetts case in which a juvenile court judge found seventeen-year-old Michelle Carter guilty of involuntary manslaughter for pressuring her boyfriend, eighteen-year-old Conrad Roy III, into killing himself through text messages and a final phone call. The ruling made Massachusetts the first jurisdiction to hold that words alone, delivered remotely, could satisfy the wanton or reckless conduct standard for manslaughter. It has shaped how prosecutors, courts, and legislatures across the country think about verbal coercion, suicide, and the limits of the First Amendment.
What Happened
Carter and Roy lived about an hour apart in southeastern Massachusetts and met in person only a handful of times. Their relationship played out almost entirely in text messages and phone calls. Roy had a documented history of depression and a prior suicide attempt, both of which he discussed openly with Carter.
Early in their exchanges, Carter urged Roy to seek professional help. Over time her tone reversed. She began researching methods of suicide and sending him information about carbon monoxide poisoning, including that inhaling a certain concentration for five to ten minutes would cause him to lose consciousness painlessly. When Roy hesitated or delayed, she questioned his commitment and pushed harder.
On July 12, 2014, Roy drove his pickup truck to a Kmart parking lot in Fairhaven, Massachusetts, and rigged a water pump inside the cab to generate carbon monoxide. He was on the phone with Carter during the final minutes. At one point he got out of the truck. Carter told him to get back in. He did, and he died of carbon monoxide poisoning that night.
Why the Charge Was Involuntary Manslaughter
Massachusetts had no statute directly criminalizing the encouragement of suicide, so prosecutors used the state’s involuntary manslaughter law. That crime is an unlawful killing unintentionally caused by wanton or reckless conduct: intentional behavior creating a high degree of likelihood that substantial harm will result.1Massachusetts Court System. Model Jury Instructions on Homicide – VII Involuntary Manslaughter It does not require an intent to kill.
Applying that framework to a case without physical contact was unprecedented. The prosecution’s theory was that Carter’s sustained pressure and her final instruction to Roy amounted to conduct reckless enough to meet the standard. She had detailed knowledge of the method, she grew impatient with his delays, and in the critical moment she told him to get back in. Prosecutors also pointed to a later text Carter sent a friend, saying she had been on the phone with Roy when he died and could have stopped it.
Carter’s attorneys argued that Roy made his own decision. They pointed to his depression, his earlier attempt, and his own research into methods, all of which predated the relationship. They also raised a First Amendment defense, arguing that text messages and phone calls are protected speech.
What the Judge Actually Ruled
Carter waived her right to a jury trial. Judge Lawrence Moniz of Bristol County Juvenile Court decided the case, and his reasoning was narrower than the prosecution’s broad theory.
Moniz concluded that the thousands of text messages Carter sent encouraging Roy’s suicide were not, standing alone, the legal cause of his death. Roy had planned his suicide independently.2GBH. Michelle Carter Found Guilty The conviction turned on the final phone call. When Roy stepped out of the truck as it filled with carbon monoxide, the judge found, he broke the chain of events leading to his own death. At that moment he was no longer killing himself. Carter’s instruction to get back in restarted the chain, and that specific instruction was the wanton and reckless conduct that created a high likelihood of serious harm.3CBS Boston.

The distinction narrowed the legal holding. The judge did not rule that encouraging suicide by text is automatically manslaughter. He ruled that in this specific factual scenario, a direct command to someone who had momentarily stepped back from the brink, delivered by someone with full knowledge of the danger, crossed the line from speech into reckless conduct.
The First Amendment Question
The First Amendment defense was the most closely watched issue in the case. Carter’s lawyers argued that convicting her amounted to punishing her for the content of her speech.
The Massachusetts Supreme Judicial Court rejected that argument when it affirmed the conviction. The court reasoned that Carter’s words were integral to a course of criminal conduct, a doctrine drawn from the U.S. Supreme Court’s decision in Giboney v. Empire Storage & Ice Co. Under that principle, conduct does not become constitutionally protected simply because it is carried out through language. The SJC concluded that Carter’s speech was not advocacy or opinion but a direct instruction that caused another person’s death.4Justia Case Law.

Some legal scholars have criticized that approach. They argue the court should have applied the test from Brandenburg v. Ohio, the standard framework for speech advocating illegal action, which requires that the speech be directed at inciting imminent lawless action and be likely to produce it. Whether Carter’s conduct would survive Brandenburg is an open question the U.S. Supreme Court chose not to answer.
Sentence, Appeals, and Release
Judge Moniz sentenced Carter to two and a half years in prison, with fifteen months to be served and the remainder suspended, followed by five years of probation.5ABC News. Michelle Carter, Convicted in Texting-Suicide Case, Released Early for Good Behavior She remained free during her appeal.
In February 2019, the Massachusetts Supreme Judicial Court affirmed the conviction. The court addressed causation directly, concluding 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 [his] truck and poisoned himself to death.”4Justia Case Law.

Carter’s attorneys then petitioned the U.S. Supreme Court on First Amendment grounds. On January 13, 2020, the Court declined to hear the case, leaving the Massachusetts ruling in place.6SCOTUSblog. Carter v Massachusetts
Carter began serving her sentence in February 2019 and was released in January 2020 after approximately eleven months. The Bristol County Sheriff’s office described her as a “model inmate” who earned time off for good behavior and program participation.7Boston 25 News.

The Wrongful Death Lawsuit
Roy’s mother, Lynn Roy, filed a $4.2 million wrongful death lawsuit against Carter in August 2017. In April 2019, the case was dismissed with prejudice, meaning it cannot be refiled. Attorneys for both sides confirmed the matter had been “resolved” without disclosing financial terms.8NBC News. Wrongful Death Lawsuit Against Michelle Carter Who Encouraged Boyfriend’s Suicide Is Dismissed A dismissal with prejudice following that kind of statement is generally consistent with a settlement, but the amount remains confidential.
Conrad’s Law and the Statutory Gap
Part of what made the Carter prosecution so unusual was that Massachusetts had no statute directly addressing suicide encouragement. Prosecutors had to fit her conduct into the existing manslaughter framework, which made the case legally fragile. In response, Lynn Roy helped draft legislation known as Conrad’s Law, which would specifically criminalize intentionally coercing or encouraging another person to die by suicide. The proposal carries a maximum sentence of five years and targets conduct that manipulates a vulnerable person’s fears, emotions, or personal bonds.9CBS Boston. Bill Would Penalize Those Who Press Others to Die by Suicide
As of the most recent reporting, Conrad’s Law has not passed. Massachusetts remains one of a small number of states without a statute explicitly criminalizing the coercion of suicide. In most of the country, a prosecutor facing similar facts would have a direct statute to work with rather than needing to rely on a manslaughter theory.
Why the Case Still Matters
Commonwealth v. Carter established that under the right circumstances, remote verbal pressure can satisfy the causation and recklessness requirements for manslaughter. The ruling itself was narrow, tied to a specific moment: Roy stepping out of the truck and Carter telling him to get back in. A slightly different set of facts, where the encouragement was persistent but no single command was so directly linked to the death, might have produced a different outcome.
The U.S. Supreme Court’s refusal to take the case left the First Amendment question unresolved at the national level. Lower courts and future defendants are working without clear guidance on where protected speech ends and criminal verbal coercion begins. Carter’s defense attorney said after the cert denial that “many legal scholars and many in the legal community understand the dangers this precedent created.”10GBH.

Carter remains the most prominent and most contested precedent for holding someone criminally responsible for another person’s suicide based on words alone.
