A Belmont woman was sentenced to five years in federal prison for helping traffic fentanyl into New Hampshire from Massachusetts.

Heidi Langevin, 44, previously pleaded guilty in U.S. District Court on Oct. 30 for her participation in a fentanyl trafficking conspiracy.

Langevin sold fentanyl and methamphetamine to a confidential informant for the FBI on two separate occasions in the Granite State, according to court records. Langevin also arranged for several men, traveling together from Belmont, to buy fentanyl from a supplier in Lawrence, Mass., on May 31, 2017. On the group’s trip back, New Hampshire State Police conducted a motor vehicle stop and seized a firearm and a package containing approximately 111 grams of the drug.

“The five-year prison sentence imposed in this case should send a message to interstate drug traffickers,” U.S. Attorney Scott Murray said in a statement. “Law enforcement officers are watching and federal prison sentences await those who get caught.”
