A 36-year-old Chicago man was sentenced to a year in a house of correction and ordered to pay restitution to the MBTA after he was convicted of more than a dozen counts of vandalism targeting MBTA property, Suffolk County prosecutors said.

John Biesiot was convicted Wednesday in Brighton Municipal Court of 15 counts of vandalism in three tagging incidents. The incidents happened in 2008 and 2010 at Codman Yard in Dorchester, Reservoir Yard in Brighton, and Alewife in Cambridge, Suffolk County District Attorney Daniel F. Conley’s office said in a statement.

He was acquitted of vandalism charges in other incidents at the Forest Hills and Orient Heights stations.


“This was a massive vandalism spree that carried massive cleanup costs,” Conley said. “The jury clearly recognized its scale and scope.”

“The defacing of public property is not a victimless crime; it costs taxpayers money and diverts resources away from the rest of the MBTA system, from cleaners to Police,” said Transit Police Chief Paul MacMillan. “I’m glad to see yesterday’s verdicts against this repeat offender and hope that it serves as warning to those who try and perpetrate crimes in the MBTA system that they will be caught and prosecuted to the fullest extent of the law.”

Biesiot — who prosecutors said had faced similar charges in Arkansas, California, Illinois, Minnesota, Missouri, and North Carolina — is slated to return to court Oct. 29 for a restitution hearing.
