Dorchester man sentenced in 2011 slaying of Brockton man; motive was dispute over car repair
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, Suffolk District Attorney Daniel F. Conley’s office said. 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.
