Court hears case of teen who sent beau texts urging suicide

BOSTON -- Dozens of text messages a teenage girl sent to her boyfriend that encouraged him to kill himself were just words and do not constitute a crime, her lawyer told the state's highest court Thursday.

But a prosecutor argued Michelle Carter pressured Conrad Roy III for weeks to end his life and engaged in "emotional manipulation" of a vulnerable teen who had struggled with depression and previously attempted suicide.

The Supreme Judicial Court heard arguments in Carter's appeal of a juvenile court judge's refusal to dismiss the manslaughter charge stemming from Roy's 2014 death.

The justices made it clear they were struggling with whether Carter's actions met the definition of manslaughter, peppering both sides with questions about what she did to encourage or assist Roy's suicide.

Justice Robert Cordy questioned assistant district attorney Shoshana Stern about what he called the "$100,000 question" in the case: "When did this cross the line -- when did these words cross the line?"

In addition to the many text messages encouraging Roy to kill himself, Stern said, Carter also spoke on the phone with him while he was in his truck inhaling carbon-monoxide fumes.

When Roy got out of his truck, she told him to "get back in," Stern said.

"I think what we can say that we know is that she was way over the line when she told him to get back in the truck," Stern said.

But Carter's attorney Dana Curhan said Roy was determined to take his own life.

He said Carter repeatedly tried to talk him out of it but finally gave up about two weeks before his death.

"Even when she said, 'Get back in the truck,' that was not the proximate event that resulted in his death," Curhan said.

Carter was 17 and Roy was 18 when he died in 2014.
