LOCKPORT – The judicial diversion program of court-supervised drug treatment chalked up a success Monday, as Richard P. Stefanko’s felony conviction for selling painkillers was reduced to a misdemeanor, and he was placed on three years’ probation by Niagara County Judge Matthew J. Murphy III.

Stefanko, 50, of Oliver Street, North Tonawanda, had pleaded guilty in November 2011 to third-degree criminal sale of a controlled substance for selling oxycodone to a police informant July 6, 2011. He faced up to nine years in prison if he had failed in the treatment program. The time since November 2011 will count toward his probation sentence for seventh-degree criminal possession of a controlled substance.
