ROCKLAND, Maine — State drug enforcement agents, working with several county and local police agencies in the midcoast region, have arrested five people for trafficking in prescription drugs as the result of three separate ongoing investigations in Rockland, Warren and Camden.

“It just happens that they all came together about the same time,” James Pease, special agent supervisor of the Maine Drug Enforcement Agency’s Mid-Coast Regional Task Force, said Tuesday.

As a result of the investigations, drug agents seized about $1,800 cash and prescription drugs with a combined street value of about $3,500, Pease said.

The first of the arrests occurred Thursday in Rockland, when MDEA agents and Rockland police executed a search warrant at the home of Kristen Staples, 25.

During that raid, authorities seized more than 60 hydrocodone pills and 33 Suboxone pills, as well as other evidence of drug trafficking, Pease and MDEA Director Roy E. McKinney said in a press release issued Tuesday.

Staples was arrested and charged with one count of trafficking in hydrocodone and two counts of trafficking Suboxone, each of which is a Class B felony punishable by up to 10 years in prison and a fine of up to $20,000.

The next two arrests took place on Friday in Warren, when MDEA agents along with Waldoboro police and members of the Knox County Sheriff’s Department and state police executed a search warrant at the home of Dean Feltis, 42, and Shelley Landers, 40, after an investigation into alleged drug sales that spanned several months, Pease and McKinney said.

As a result of that raid, authorities seized about $1,800 cash and other evidence of drug trafficking. Landers and Feltis each were charged with trafficking oxycodone, a Class B felony.

The two remaining arrests occurred Tuesday in Camden, when MDEA agents and Knox County and Camden police executed two search warrants at the homes of Holly Young, 29, and her mother, June Robbins, 50.

Authorities said the mother and daughter had been under investigation by MDEA agents and Camden police for several months. Agents seized 114 oxycodone pills and other evidence of drug trafficking from Robbins’ home and 44 oxycodone pills from Young at her residence.

Robbins was charged with the Class B felony crime of trafficking in oxycodone.

Young’s oxycodone trafficking charge was elevated to aggravated status because her alleged illegal drug transactions were taking place within 1,000 feet of Camden Middle School. Her aggravated trafficking charge is a Class A felony punishable by up to 30 years in prison and a fine of up to $50,000.

Pease said Tuesday that Feltis, Young and Landers all were taken to Knox County Jail in Rockland after their arrests and that all three since have been released on bail. Robbins and Staples were bailed out from their residences, he said.
