Two Mattawamkeag men were charged late Wednesday night with trafficking heroin in Penobscot County.

Scott Gagnon, 45, and Russell McAlpine, 37, both face charges after a month-long investigation by drug agents. The investigation uncovered that the two men would be returning to Maine from Massachusetts Wednesday with a significant amount of heroin for distribution in the Howland, Lincoln and Mattawamkeag areas of Penobscot County.

Agents located the vehicle traveling through Bangor on I-95 and stopped the pair in Old Town. Gagnon, who was wanted on five outstanding arrest warrants at the time of the stop, was taken into custody. A subsequent search of the vehicle, uncovered approximately 1,000 bags of heroin concealed within the car. This heroin has a street value approaching $30,000.

Both Gagnon and McAlpine were taken into custody and charged with Class A, Aggravated Trafficking in Schedule W Drugs (Heroin). The charges were aggravated due to the amount of heroin that was seized. Both Gagnon and McAlpine were taken to the Penobscot County Jail where they remain pending a $10,000 cash bail on the drug charges.
