The offender, Donta Easterbrook, pleaded guilty to assault with a weapon after an unprovoked stabbing in a subway station.
The victim sustained a neck wound but recovered physically, though experiencing emotional trauma.
The offender, 23, had a history of violent convictions, drug addiction, and mental health issues, with inconsistent engagement in treatment and expressed mixed remorse.
The court emphasized denunciation and general deterrence, particularly given the public nature of the attack.
Mitigating factors included an early guilty plea and harsh pre-trial detention conditions.
The court imposed a sentence of 10 months additional custody (totaling approximately 18 months including pre-trial credit), followed by a three-year probation order, a DNA order, and a lifetime weapons prohibition.
