VINALHAVEN, Maine — Two island residents and a Houlton man were arrested Wednesday, accused of producing methamphetamine.

More arrests are expected.

Ryan Rairdon, 25, of Houlton, Hilary Walker, 20, of Vinalhaven and Owen Adair, 23, of Vinalhaven each were charged with trafficking in methamphetamine by manufacturing, according to a news release from the Maine Drug Enforcement Agency. The Class B felony charge is punishable by up to 10 years in prison. Adair also was charged with violating a condition of release.

The arrests occurred after the Knox County Sheriff’s Office received a complaint about a possible drug lab on the island. Investigating deputies reportedly spotted several items consistent with methamphetamine manufacturing inside a small tool shed in a back yard and contacted the MDEA.

Members of the MDEA Clandestine Laboratory Enforcement Team, assigned to the MDEA Mid-Coast District Task Force, went to Vinalhaven. Upon further investigation, the agents confirmed that meth had been manufactured in the shed, according to the MDEA. Agents seized evidence of a one pot manufacturing process, including chemicals and hosing. A gas generator also was seized.

With the assistance of members of the Maine Marine Patrol, the three suspects were brought to Rockland. Rockland police officers then drove the three to the Knox County Jail.

Rairdon and Walker have since been released on $800 and $500 cash bail, respectively. Adair remained at the jail Thursday afternoon.

Agents expanded their investigation to a residence on Overlook Hill Road in Union, where they conducted interviews and allegedly seized additional evidence of methamphetamine manufacturing. The investigation is continuing and additional arrests are expected for those who assisted in the manufacturing by providing pseudoephedrine, the medication used in the process.

The name of the property owner and the address on Vinalhaven are not being released because the owner was not involved or aware of the alleged drug making operation.

This investigation was conducted with the assistance of the Knox County Sheriff’s Department, the Vinalhaven Fire Department, the Maine Marine Patrol and the Maine Department of Environmental Protection.

This is the first meth lab-related incident the MDEA has handled this year. MDEA handled 28 related incidents in 2014.
