A Sanford man was sentenced Monday to nearly 12 years in federal prison on drug and gun charges for trafficking heroin and fentanyl from Massachusetts to distribute in the Sanford area.

Jesse Roy, 37, was arrested on Oct. 20, 2014, after his roommates told police that he threatened them with a gun and officers subsequently found 94 grams of heroin, $24,500 in cash and a .380-caliber pistol in his home, according to court records.

Roy was sentenced by Judge Jon Levy in U.S. District Court in Portland to serve 140 months in prison followed by five years of supervised release for conspiracy to distribute heroin and fentanyl and possession of a firearm in furtherance of drug trafficking.

“In May and July 2015, the Defendant sent letters to co-defendant Janerys Vega setting forth a false narrative that the Defendant hoped Vega would adopt with respect to the charges against them. The Defendant agrees that he sent these letters in an attempt to obstruct the investigation and prosecution of this case,” Assistant U.S. Attorney Benjamin Block said in a prosecution document filed with the court.

The judge enhanced Roy’s sentence for trying to sway Vega and for acting as a manager in a drug trafficking ring. Roy pleaded guilty on Dec. 3, 2015, as the case neared trial.

Vega was sentenced to two years in prison followed by three years of supervised release for his role in the drug conspiracy.
