FAIRFIELD — Two Fairfield residents have been arrested after a search of their house and automobile turned up about $15,500 in illegal drugs, as well as weapons and counterfeit money, police said.

Amanda Douglass, 38, and Joshua Gray, 35, have each been charged with three counts of aggravated trafficking in scheduled drugs. Gray faces an additional charge of violating conditions of release.

“The drug charges are aggravated due to the amount of drugs seized and the presence of loaded firearms,” Somerset County Sheriff Dale Lancaster said Wednesday in a statement released to the news media.

Douglass and Gray were arrested at their residence at 120 Gagnon Road at about 8 a.m. Wednesday after the Somerset County Sheriff’s Office executed a drug search warrant.

Lancaster said his office was aided by officers from the Fairfield Police Department and agents from the Maine Drug Enforcement Agency.

A large amount of fentanyl, methamphetamine, cocaine, Suboxone strips, pills suspected to contain heroin and methylphenidate hydrochloride (a drug used to treat conditions, including attention deficit hyperactivity disorder) were found inside the pair’s residence and automobile, according to police.

The seized drugs have an estimated street value of about $15,500, according to Lancaster.

The amount of fentanyl found at the property was about 39,000 times what the Drug Enforcement Agency considers to be a lethal dose.

Also found at the property: About $9,000 in cash, suspected by authorities of being illicit drug proceeds, and counterfeit money, four loaded pistols and drug-related paraphernalia, Lancaster said.

Douglass and Gray were taken to the Somerset County Jail in East Madison. Each is scheduled to appear Oct. 4 in court in Skowhegan.
