A Massachusetts judge on Thursday sentenced a 20-year-old woman to serve 15 months in prison for encouraging her teenage boyfriend to make good on plans to kill himself while she was still a juvenile.

Judge Lawrence Moniz handed Michelle Carter a sentence of two and a half years, of which he said 15 months would be served in the Bristol County House of Corrections and the balance would be served on probation under certain conditions.

Moniz said it had been important to balance the hope of rehabilitation with punishment for her role in the death of Conrad Roy, 18, who died from carbon monoxide poisoning in his pickup truck in a parking lot in July 2014.
