ROCKLAND, Maine — Three people were arrested on drug possession and trafficking charges in Knox County last week after police raids at homes in Rockland and Thomaston, according to the Maine Drug Enforcement Agency.

Agents also seized more than $17,000 and an assortment of OxyContin 40 and 80 milligram pills, hydrocodone, Ritalin, Klonopin and Suboxone with an estimated street value of $8,000, said Roy E. McKinney, director of the MDEA, and James Pease, supervisor of MDEA’s Mid-Coast Regional Task Force.

Arrested Wednesday were Francis Scott, 64, of Rockland; Ruth Crandall, 39, of Thomaston; and Bethany Overlock, 38, of Owls Head.

On Wednesday, the MDEA, Rockland and Thomaston police, and the Knox and Lincoln County sheriff’s departments searched Crandall’s residence on Pleasant Street in Thomaston and Scott’s residence on Granite Street in Rockland.

The search warrants were served after a multiagency investigation in recent months revealed that hundreds of OxyContin pills were being sold in the two counties, according to McKinney and Pease.

Scott was arrested and charged with aggravated trafficking of OxyContin. The aggravated charge was because his home is in a school zone.

Crandall was arrested and charged with aggravated trafficking of OxyContin. The aggravated charge in her case is because of a prior conviction for trafficking illegal drugs, police said.

Overlock was arrested for possession of Aterol, Flexiril and Clonazepam and for violating conditions of release on a prior domestic assault charge.

Overlock and Crandall where taken to Knox County Jail. Overlock was released on bail, a jail official said Saturday. He said Crandall was not at the jail Saturday, but he did not elaborate. Scott was bailed from his home after he was arrested.
