Investigators from the Maine Drug Enforcement Agency’s Ellsworth office have charged two Hancock County men with felony drug distribution following a monthlong investigation into the sale of heroin in the county, according to the Maine Department of Public Safety.

Sheldon Alley, 30, of Eastbrook, is charged with Class A aggravated trafficking in heroin. Paul Colbeth, 35, of Sorrento, is charged with one count of Class B trafficking in heroin.

Drug agents served a search warrant at Alley’s residence on Webb Pond Road on Jan. 15 and seized about 115 grams of heroin with an estimated street value of $40,000, $2,200 in cash, which is suspected of being proceeds from illegal drug sales, a video surveillance system and two firearms, MDEA Commander Peter Arno said in a news release Tuesday.

Participating in the arrests were officers with the Hancock County Sheriff’s Department, the Ellsworth Police Department and Maine State Police.

Arno said the seizure was significant and indicates a disturbing prevalence of heroin in Hancock County and other Maine communities.

This investigation is continuing and other charges are probable, he said.

Anyone with information about drug trafficking is urged to contact their local police department, an MDEA office or by calling the MDEA tip line at 800-452-6457.
