LEWISTON — One of two men who have pleaded guilty to federal charges in a cocaine ring operating in the Twin Cities from early 2012 until June 2013 has been sentenced.

Brian Wilkerson, 36, of Dorchester, Mass., was sentenced Monday in U.S. District Court to 15 years in federal prison and eight years of supervised release for conspiring to distribute cocaine. According to a news release from U.S. Attorney Thomas E. Delahanty’s office, Wilkerson pleaded guilty Oct. 28, 2013.

The other man, David Goyette, 27, of Lewiston pleaded guilty last month to conspiracy to distribute 500 grams or more of cocaine and 28 grams or more of crack cocaine. He has not yet been sentenced.

According to court records, from 2011 through June 2013, Wilkerson supplied cocaine to Goyette in Auburn, who cooked some of it into crack cocaine and distributed both substances in the Lewiston-Auburn area.

According to court officials, on June 3, 2013, Goyette made plans to meet Wilkerson the next day in Boston. Police and drug agents followed Goyette as he drove from Auburn to Boston, according to court records.

In Boston, police watched as Goyette and Wilkerson met, then left in separate vehicles. Shortly after, both vehicles were stopped and agents said they recovered about $25,000 in Wilkerson’s vehicle.

The following day, search warrants were executed at Goyette’s and his mother’s residences in Auburn. In a closet outside the mother’s apartment, court officials said, agents recovered about 500 grams of cocaine and a digital scale. Inside Goyette’s apartment, agents recovered expensive jewelry.

Goyette faces between five and 40 years in prison and a $5 million fine. He will be sentenced after a presentence investigation report by the U.S. Probation Office.

The joint investigation was conducted by the U.S. Drug Enforcement Administration, the Maine Drug Enforcement Agency and the Auburn Police Department, and the ongoing effort of the Organized Crime Drug Enforcement Task Forces, a partnership between federal, state and local law enforcement agencies.
