CALGARY (CBC) - A 20-year-old woman convicted for her part in the gruesome sex killing of a 13-year-old Edmonton girl three years ago was sentenced Friday to 12 years in prison.

Stephanie Bird, 17 at the time, helped a group of young pele lure Nina Courtepatte from West Edmonton Mall to a secluded golf course, where the girl was raped and beaten to death.

Bird was found guilty in April 2007 on charges of kidnapping, aggravated sexual assault and manslaughter.

Last week during her sentencing hearing, she made a tearful apology to Courtepatte's family after the judge ruled that she would be sentenced as an adult, rather than a youth, because of the seriousness of the crime.

Bird's identify has been protected throughout the lengthy court process, but Justice June Ross dropped the publication ban after sentencing Friday.

Ross rejected a call from the Crown that the women be sent to prison for 25 years. Bird still has a chance for rehabilitation and is young enough to turn her life around, the judge said.

The judge also allowed three years of credit for her time already served in jail.

Bird is one of five people charged in the disturbing case.

Joseph Laboucan and Michael Williams are now serving life sentences. Another accused, Michael Briscoe, was acquitted, although the Crown is appealing that decision.

The trial for a fifth young woman, now 18 but 15 at the time of the crime, began this week in another Edmonton courtroom.

She is charged with first-degree murder, aggravated sexual assault and kidnapping.
