The offender was convicted by a jury of second-degree murder for the stabbing death of his stepmother in her home.
The Crown sought a 20-year period of parole ineligibility, while the offender sought 15 years.
The court considered the brutal nature of the murder, the breach of trust, the offender's post-offence conduct in attempting to conceal evidence, and the jury's recommendation of 25 years.
The court set the period of parole ineligibility at 17 years, emphasizing denunciation and deterrence.
