HOULTON, Maine — A 22-year-old resident of Houlton and Dexter has been arrested and charged with trafficking in methamphetamine, police announced Friday.

When arrested earlier this week, Brian Flewelling became the fifth suspect charged in the last three weeks in connection with methamphetamine manufacturing facilities that state drug enforcement officials believe have been operating in Houlton.

On Nov. 15, about a dozen agents and a forensic chemist with the Maine Drug Enforcement Agency uncovered evidence at three locations in Houlton that indicated the drug was being manufactured there, according to MDEA Division Commander Darrel Crandall.

The Class B charge against Flewelling is based on evidence that he assisted Kenneth Moore, who also was charged in the case, in manufacturing methamphetamine in the days leading up to the discovery of the labs, Crandall said Friday. A Class B charge is punishable by up to 10 years in prison and a fine of up to $20,000.

MDEA lab teams searched locations on Foxcroft Road and First Street and in a wooded area at the end of First Street. Crandall said agents recovered evidence that included chemicals, solvents and other items typically used in the drug manufacturing process.

Arrested earlier this month and charged with trafficking in methamphetamine were: Melissa Tidd, 28, of Houlton; Kenneth Williams, 41, of Lakeland, Fla.; and Kenneth Moore, 33, of Houlton.

Earlier this week, Nancy Hardy-Boles, 31, of Houlton was charged with aggravated trafficking in methamphetamine. Hardy-Boles’ Foxcroft Road property was one of the locations the MDEA’s lab team examined after obtaining a search warrant.

Hardy-Boles faces the most serious charge, Class A aggravated trafficking, because of her criminal record. In Maine, a Class A offense is punishable by no less than four years and up to 30 years in prison.

She was convicted of a Class B drug trafficking offense in 2004 and a Class B trafficking offense in 2008. The 2008 offense originally was charged as a Class A aggravated offense, but a plea bargain resulted in the reduced charge, according to Crandall.

Flewelling was taken into custody in Houlton and remains at Aroostook County Jail.

“While evidence may surface to warrant charging additional suspects, we believe we have now charged those primarily responsible,” Crandall said Friday. “The investigation will continue until we believe we have spoken with everyone who may have witnessed or participated in any of the criminal activity.”
