PORTLAND — A 49-year-old Maine man has been sentenced to 18 ½ years in prison for his role in a cocaine distribution operation.

Kenneth Pelletier, of Lyman, was sentenced Tuesday in U.S. District Court in Portland.

Pelletier pleaded guilty last August to traveling to New York on multiple occasions and picking up crack cocaine, which was then distributed in York County. In all, he was held responsible for distributing nearly 4 pounds of the drug.

The U.S. Attorney’s Office says Pelletier has 24 criminal convictions on his record, including three for drug trafficking.
