The Massachusetts Supreme Court decided on Wednesday, February 6th, to uphold the involuntary manslaughter conviction of Michelle Carter, who encouraged her boyfriend’s suicide over text messages. Carter will serve 15 months in prison for the 2017 conviction that held her responsible for the suicide of her boyfriend, Conrad Roy III.

In July 2014 Carter, who was then 17 years old, was texting with her boyfriend Conrad Roy as he attempted suicide in his Ford F-250 truck by inhaling carbon monoxide. When Roy expressed that he could not go through with it, Carter told him to “get back in.”

Her 15-month conviction had been on hold until the Supreme Court’s ruling. Carter’s defense had arguing that Carter’s actions were protected under the first amendment, but the court did not see it as such.

The court explained in their ruling: “The evidence against the defendant proved that, by her wanton or reckless conduct, she caused the victim’s death by suicide. Her conviction of involuntary manslaughter as a youthful offender is not legally or constitutionally infirm. The judgement is therefore affirmed.”
