A 17-year-old youth was found guilty of attempting to murder his 8-year-old foster sibling by slitting the child's throat while the child slept.
The youth called 911 and turned himself in, acknowledging his intention to fatally harm the victim.
The victim survived by millimetres when the jugular vein was missed.
The court imposed a 27-month custody and supervision order under the Youth Criminal Justice Act, balancing the serious nature of the offence against the youth's troubled background, mental health issues, and prospects for rehabilitation.
The court granted credit for pre-sentence custody, addressing the statutory requirement to take detention into account and the principles of the YCJA.
