What happened in Commonwealth v. Michelle Carter
In 2017, a Massachusetts jury convicted Michelle Carter of involuntary manslaughter in the death of Conrad Roy, her boyfriend, who died by suicide in a truck cab filled with carbon monoxide in July 2014. The case drew national attention because text messages showed Carter repeatedly urging Roy to leave the truck and "get out" rather than seek help. The legal question centered on whether Carter’s words and omissions met the state standard for criminal recklessness and gross negligence, creating a case that clarified how verbal encouragement can support involuntary manslaughter convictions when a special relationship exists and a person consciously fails to seek outside intervention.
Key facts of the case
On August 7, 2014, Conrad Roy, 18, died inside a pickup truck at a Massachusetts industrial park. Toxicology reported carbon monoxide as the cause of death. Over days leading to his death, Carter exchanged hundreds of text messages with Roy that included direct encouragement to overcome hesitation and enter the truck. After local emergency responders failed to save him, investigators focused on the content of the messages and Carter’s failure to call 911. A jury later weighed whether her conduct rose to criminal recklessness under Massachusetts law.
Legal charges and conviction
Prosecutors charged Carter with involuntary manslaughter and several other counts tied to misleading emergency calls and evidence. In July 2017, a jury found her guilty on the involuntary manslaughter count. The court emphasized that Carter, who had been in a relationship with Roy and knew he was in distress, took substantial steps that created a dangerous situation and failed to take reasonable action to mitigate harm. Her conviction underscored that individuals who actively encourage life-threatening conduct can face serious criminal liability.
Sentence and appeals process
Judge Lawrence Moniz sentenced Carter to 15 months in jail, with the sentence split between jail time and probation, and imposed a 10-year probation period with strict conditions. Carter appealed, arguing evidentiary and jury instructions issues, but the Massachusetts Supreme Judicial Court upheld the conviction in 2019. The appeals ruling affirmed that the jury could reasonably find her grossly reckless and that the trial court did not abuse discretion in admitting messages and in instructions regarding her legal duties to act.
Meaning for criminal law in the digital age
The decision clarified how courts treat digital encouragement in suicide contexts. It confirmed that text messages and other forms of communication can satisfy the intent requirements for involuntary manslaughter when the defendant consciously disregards a substantial and unjustifiable risk. By setting boundaries around when encouragement crosses into criminal recklessness, the case remains a key reference for prosecutors, defense attorneys, and courts weighing duties of care in online and offline relationships.

Common questions about the case
- What was the relationship between Carter and Roy? They were dating; Carter was older and served as a stabilizing presence, which the court said heightened her responsibility.
- Why was Carter convicted of involuntary manslaughter and not second-degree murder? The jury found her conduct grossly negligent and reckless rather than intentionally causing death, fitting the lesser included offense of involuntary manslaughter.
- Did the messages alone justify the conviction? The messages were critical evidence, but the jury also considered Carter’s failure to call 911 and her role in creating the dangerous environment.
- Can mere encouragement be a crime? Yes, when the encouragement involves a conscious creation of a grave risk of death and the actor has a special relationship and ability to act, as this case illustrates.
