FAIRFIELD — A married couple was arrested this week after a police raid found narcotics, firearms and cash in their home, authorities said Thursday.

Amanda Douglass, 38, and William Douglass, 38, were arrested at around 9 a.m. Wednesday after police found more than 40 grams of fentanyl, methamphetamine, cocaine and ecstasy in their residence on Gagnon Street, according to Somerset County Sheriff Dale Lancaster. Two loaded pistols and nearly $4,000 in suspected proceeds were also seized.

“They were selling at this residence,” Lancaster said. “These investigations are with the ultimate goal to eliminate illegal activity in Somerset County.”

A search warrant was issued for the property after an ongoing investigation into illegal drug sales throughout Kennebec and Somerset counties, Lancaster said. Officers from the U.S. Drug Enforcement Administration  and Maine Department of Corrections helped execute the warrant.

Amanda Douglass was charged with aggravated trafficking in scheduled drugs and had an outstanding warrant for a probation violation, Lancaster said. She was on probation after having previously been arrested at the same residence in July for similar charges unrelated to Wednesday’s arrest. She’s being held on $50,000 bail.

William Douglass was arrested on charges of violating conditions of release and aggravated trafficking in scheduled drugs. He was also on probation for an unrelated drug charge in Franklin County, according to Lancaster. He’s being held without bail.

Both are currently being held at the Somerset County Jail. They are scheduled to appear in court  July 3 at the Somerset County Unified Criminal Court.
