A Norridgewock man arrested on drug charges in October pleaded guilty Wednesday in federal court as part of the U.S. Drug Enforcement Administration and the Department of Justice’s strategy to combat the opioid epidemic.

Brandon Lancaster, 21, pleaded guilty in U.S. District Court to distributing oxycodone, according to a release from United States Attorney Thomas E. Delahanty II.

On Aug. 31, 2016, in a Pittsfield parking lot, Lancaster sold 11 30-milligram oxycodone pills for $500 to a person working with law enforcement, according to court records.

Kristopher Sullivan, a special agent with the U.S. Drug Enforcement Administration, filed an affidavit in court saying that he witnessed a confidential informant purchasing the tablets from Lancaster. Sullivan said the transaction was funded with $500 in government money.

Sullivan said he followed Lancaster again Oct. 18 until Lancaster was stopped in Sidney. Documents show he was arrested by federal authorities.

Lancaster faces up to 20 years in prison, a $1 million fine and between three years and his whole life on supervised release. He will be sentenced after the completion of a pre-sentence investigation report by the U.S. Probation Office.
