A 43-year-old Norwich man was sentenced to about 14 years in prison followed by three years of supervised release for selling fentanyl on the dark web and for firearm offenses, according to a news release from the office of the United States Attorney for the District of Connecticut.

The man, Barry Duclos, advertised the sale of fentanyl analogues on a page he ran on the dark web and then shipped them through the mail to customers, who paid with Bitcoin, according to evidence presented during his trial, the release stated. A 39-year-old Tennessee man overdosed in 2017 from cyclopropyl fentanyl sold by Duclos, according to the release.

In 2018, Duclos was arrested on a federal criminal complaint, and a search of his apartment revealed "a YHM rifle with multiple magazines, two of which were extended magazines," according to the release.

“The firearm was loaded with a round in the chamber,” the release stated. “Investigators also located and seized fentanyl and carfentanil from the residence."

Duclos was convicted in state court in 2001 for sale of narcotics and in 2017 for third-degree larceny, the release stated.

In 2021, Duclos was found guilty of seven counts of possession with intent to distribute and distribution of fentanyl analogues; one count of possession with intent to distribute fentanyl and carfentanil; one count of possession of ammunition by a convicted felon; and one count of possession of a firearm in furtherance of a drug trafficking crime, the release stated.
