A 39-year-old Dorchester man was sentenced today to 15 years in state prison for his role in the shooting death last year of a 36-year-old Brockton auto mechanic over a car repair dispute, prosecutors said.
Mario Burns pleaded guilty to manslaughter one day after his trial began in Suffolk Superior Court.
Burns was angry with Charles Cantave about a used engine Cantave had installed in Burns’s wife’s car. The two men had gone to small claims court over the issue, Suffolk District Attorney Daniel F. Conley’s office said.
