Girl who texted boyfriend urging suicide must stand trial, court rules

Massachusetts' highest court has ruled that a teenage girl must stand trial on a manslaughter charge for encouraging her boyfriend to kill himself by sending him dozens of text messages and telling him to "get back in" a truck filled with carbon monoxide fumes.

The Supreme Judicial Court ruled Friday that a grand jury had probable cause to indict Michelle Carter in the 2014 death of 18-year-old Carter Roy III.

"The court said that in the future they would look at the facts of individual cases and it is possible to be charged with involuntary manslaughter even if you’re not actively engaged in it, and you're just encouraging it or cheerleading it,” criminal defense attorney Peter Elikan said.

Carter's lawyer said her texts were protected by the First Amendment and didn't cause Roy to kill himself.

But the court noted that the grand jury heard evidence suggesting that Carter engaged in a "systematic campaign of coercion" that targeted Roy's insecurities and that her instruction to "get back in" his truck in his final moments was a "direct, causal link to his death."

"They really were in uncharted territory here, they’ve never made a ruling that mere speech could get you charged with involuntary manslaughter,” Elikan said.
