Overview

• Costanzo pleaded guilty to manslaughter by criminal negligence and received a five-year prison sentence with a three-year non-parole period.
• Having already served more than a year in custody, he could be released in under two years.
• Court records show he pursued 76-year-old Peter Row in an unlit truck and struck him near a bend after an earlier confrontation.
• After the collision he fled the scene and lied to police, conduct Justice Incerti described as callous.
• He faces a 24-month driving disqualification and the judge cited his age, family support and good prison behaviour as positive signs for rehabilitation.
