Michelle Carter is scheduled to appear in court Monday when a judge will consider prosecutors’ request that she begin serving her 15-month sentence.
Carter was convicted in 2017 of involuntary manslaughter for her role in the death of Conrad Roy III. A judge allowed Carter to remain free while she appealed in state court.
Massachusetts’ highest court upheld her conviction last week.
Her lawyers say in an emergency motion filed in the Supreme Judicial Court Monday that her sentence should be further delayed.
The courts found Carter caused Roy’s death when she instructed him to get back in his truck that was filling with toxic gas.
