BURLINGTON, Vt. — Two men have been sentenced to lengthy prison terms for leading a large drug trafficking organization in Vermont and Maine.

The U.S. Attorney’s office in Vermont says Gary Delima was sentenced federal court in Burlington on Thursday to 13 years in prison and Sharif Cargo was sentenced to 11 years on trafficking and fraud crimes. Both are 28 and are from New York.

Court records say they were leaders of a group that imported heroin and cocaine base to multiple communities in Vermont and Maine from 2012 to 2015. They used local addicts to function as hosts for out-of-state co-conspirators, providing safe harbor for the drugs. Police have linked their activities to at least one overdose death.

Delima and Cargo were arrested in Lewiston, Maine.
