A young Eastern Passage woman accused of murdering her ex-boyfriend has pleaded guilty to manslaughter.

Amanda Allison Greene, 19, appeared in Halifax Supreme Court Thursday morning. She was originally charged with first-degree murder, but today both the Crown and defence expressed that manslaughter is an appropriate charge for the teen.

Dillon Jewett's body was found in a quarry in East Uniacke, north of Halifax, in October 2010. A group of people had been riding bikes and all-terrain vehicles in the area when they discovered Jewett's body and called 911.

Steven Shaun Gowen and his brother Kyle Brian Gowen, also of Eastern Passage, have already been sentenced for their involvement in Jewett's death.

Steven Gowen, 21, pleaded guilty to accessory to murder after the fact and was sentenced to three years in prison on June 9.

He had been in prison since he was arrested in October 2010. The time he has already served will count towards his sentence, which means he will remain in prison for another two years and four months.

Kyle Gowen, 23, admitted during his trial that he shot Jewett in the head. He pleaded guilty to second-degree murder and was sentenced to life in prison with no chance of parole for 15 years on June 7.

Greene is free on bail but she must follow conditions set by the court. She has been ordered to stick a curfew and must be in the care of a guardian – her mother, father, or stepmother - when she goes out.

She is due back in Halifax Supreme Court for sentencing on October 25.
