WARREN — One of the largest drug busts in Knox County’s history has resulted in the arrests of three people.

Steve McCausland, spokesman for the Maine Department of Public Safety, said today that agents for the Maine Drug Enforcement Agency seized more than 950 bags of heroin from a home in the midcoast town of Warren Wednesday night.

McCausland said the drugs have an estimated street value of $19,000. Agents also seized scales, packaging materials, and an assortment of needles from a home on Riverside Drive.

Shawn Leclerc, 26, and his girlfriend, Tonja Hallett, 25, who live in the home, were arrested and charged with aggravated trafficking of heroin and importation of heroin.

Also arrested on the same charges was Angel Jones, 25, of Rockland. Jones allegedly drove the car back to Maine from Rhode Island with Leclerc and Hallet as her passengers.

James Pease, the supervisor of the Maine Drug Enforcement Agency, called the drug bust “huge” and one of the largest of its kind in Knox County.

Pease said Leclerc has been suspected of selling hundreds of bags of heroin from his home over the past four to six months.

Jones has been released on $500 cash bail, but Leclerc and Hallett remain in custody in the Knox County Jail. They are scheduled to appear in Rockland District Court on Friday.
