LOCKPORT – A Lockport man described by a Niagara County Drug Task Force officer as “a heavy drug dealer” was sentenced to an additional 18 months in state prison Tuesday.

Kurtis R. Washington, 22, of Cottage Street, had pleaded guilty in November to fifth-degree criminal sale of a controlled substance for selling cocaine Dec. 5, 2011, on Elmwood Avenue in Lockport.

The decision by County Judge Matthew J. Murphy III came as Washington was expecting to be released from a six-month state prison “shock incarceration” program next week on his previous conviction for attempted fourth-degree criminal possession of a controlled substance. He had crack cocaine in Lockport Dec. 17, 2011.
