Nine people, including a pair in Kennebec County, have been arrested on felony drug charges following a months-long investigation in Aroostook County by the Maine Drug Enforcement Agency.

MDEA Commander Darrell Crandall said Kurt Doody, 22, of Caribou, and Autumn Parady, 20, of Gardiner, but previously of Caribou, were both arrested in Augusta last week and both were charged with trafficking in fentanyl. They had relocated before the investigation was complete.

Police say the investigation, which started in late 2017, involved surveillance, interviews and undercover drug buys.

Also arrested were:

• Lucas Wynn, 31, of Presque Isle, trafficking in methamphetamine

• Scott Pelletier, 28, of Limestone, trafficking in heroin

• Tyler Cyr, 31, of Caribou, trafficking in methamphetamine

• George Tamberello, 31, of Caribou, trafficking in crack cocaine

• Brian Cyr, 36, of Caribou, trafficking in crack cocaine

• Chris Tuttle, 30, of Presque Isle, trafficking in heroin

• Nicholas Hall, 33, of Presque Isle, trafficking in heroin.

Doody remains in the Kennebec County jail; Parady has posted bail.

Drug agents are seeking three more people as part of the investigation. They are Amber Shaw, 30, and Josh Easler, 29, both of Presque Isle, and Fernando Vazquez, 41, of Springfield, Massachusetts.

These offenses are Class B crimes, which carry a maximum sentence of 10 years.

The Aroostook County Sheriff’s Office, the Maine State Police, the Caribou Police Department, the Presque Isle Police, the Limestone Police Department, and the Augusta Police Department helped the MDEA with the investigation and locating and arrested the suspects.

Police asked that anyone with information on the whereabouts of Easler and Shaw to call the Aroostook County Crimestoppers at 800-638-8477 or text 207-538-8477.
