A Dominican man will join his older brother in prison for his role in a conspiracy to bring large amounts of fentanyl into Maine.

U.S. District Court Judge Stacey Neumann handed down the four-year sentence against 26-year-old Ramon De Leon on Tuesday in Bangor, according to the U.S. attorney’s office.

De Leon and his co-conspirators, including his brother, 30-year-old Alexis, funneled fentanyl into Maine from Massachusetts, using Facebook and other means to contact associates, distributors and customers, the U.S. attorney’s office said.

Federal drug agents and Maine state troopers stopped De Leon and his brother in June 2024 while they were headed to Bangor with a shipment of fentanyl.

De Leon was found to have trafficked just over 44 pounds of fentanyl into Maine, according to the U.S. attorney’s office.

He pleaded guilty to his role in the conspiracy on Oct. 22, 2025.

Alexis De Leon was sentenced to five years in prison back in January; Mandi Ford was sentenced to time served in February; Brady Bellfleur was sentenced to six years in prison in May; and Andrew Marin was sentenced to 12 months and one day in prison in June.
