A Wiscasset couple faces charges of drug trafficking after investigators found evidence they were dealing heroin and prescription painkillers, police said.

Police charged Brandon Nelson, 25, with aggravated trafficking in heroin and Elise Cowing, 18, with trafficking in heroin, said James Pease, supervisor with the Maine Drug Enforcement Agency.

Officers from the MDEA, Wiscasset, Lincoln County and State Police executed a search warrant at the couple’s Route 27 apartment Friday. They found heroin, OxyContin and a scale.

Nelson also had OxyContin with him when he was arrested at Round Pond at his job as a house painter.

Both are free on bail from Two Bridges Jail pending a September court date.
