Conrad Henri Roy III (September 12, 1995 – July 13, 2014) was an American teenager who died by suicide at the age of 18. His girlfriend, 17-year-old Michelle Carter, had encouraged him in text messages to kill himself. The case was the subject of a notable investigation and involuntary manslaughter trial in Massachusetts, colloquially known as the "Texting suicide case." It involved scores of text messages, emails, and phone calls recorded between Carter and Roy in the lead up to his death, in which Carter repeatedly texted Roy to kill himself; Roy had seen numerous mental health professionals and had been prescribed psychiatric medication.
