Michelle Carter, the Massachusetts woman convicted of urging her boyfriend via text messages to kill himself, on Friday was denied her request for early release by the state Parole Board.

“The [board] is troubled that Ms. Carter not only encouraged [Conrad Roy III] to take his own life, she actively prevented others from intervening in his suicide,” the board wrote in its decision.

“Ms. Carter’s self-serving statements and behavior, leading up to and after his suicide, appear to be irrational and lacked sincerity,” it said, adding that she needs to address the “causative effects” that led to the offense.

“Release does not meet the legal standard,” the board said about the Plainville woman, who was convicted in 2017 of involuntary manslaughter and is serving a 15-month sentence for the 18-year-old man’s death in 2014.

Roy died after filling his pickup truck with poisonous fumes. When he had second thoughts, Carter texted him to “get back in” the vehicle.

Lawyers for the 22-year old woman, who began her sentence in February, have argued that her texts were constitutionally protected free speech.

The lawyers, who appealed her conviction to the US Supreme Court, declined to comment Friday.

A lawyer for Roy’s family didn’t respond to an email from the Associated Press.

Despite the setback, Carter will still get out of jail at least two months early because she is a “model” prisoner, officials said Thursday.

Carter has been working in the jail kitchen and attending classes and programs; each month she does so, she earns another 10 days off her sentence, officials said, and is on track to be sprung in mid-March, rather than her originally set release in mid-May.
