The offender was convicted of second degree murder for stabbing a 16-year-old victim to death and attempted murder for stabbing a 17-year-old victim.
The Crown sought a 16-year parole ineligibility period, while the defence sought 12 to 14 years.
The court considered the offender's lengthy and violent criminal record, his non-compliance with court orders, and the vicious, unprovoked nature of the attack on unsuspecting victims.
The court set the period of parole ineligibility at 15 years.
