A New York man on parole after being convicted of attempted murder was arrested when police stopped a car in Newport on Saturday as part of an investigation into drug trafficking in Washington County.

Police allegedly found $3,000 worth of cocaine and heroin during the stop. The drugs were headed Down East.

Chuckie Langley, 32, of New York City, was charged Saturday with Class A aggravated trafficking in heroin and Class B unlawful possession of cocaine base, said Stephen McCausland, spokesman for the Maine Department of Public Safety.

Langley is on parole from New York after serving eight years for attempted murder, McCausland said in a statement released Tuesday. Langley is being held at the Penobscot County Jail without bail, he said.

Langley was among three people arrested after investigators with the Maine Drug Enforcement Agency’s district task force for Washington and Hancock counties stopped the vehicle — with help from the Maine State Police — on Interstate 95 on Saturday, McCausland said.

David Jones, 26, of the Bronx, New York, was charged with Class A aggravated trafficking in heroin and Class C violation of conditions of release.

Jones was on preconviction bail as a result of an Aug. 3 arrest in Machiasport for Class B unlawful trafficking in cocaine. Jones is being held without bail, McCausland said.

Holly Inman, 41, of Machias was charged with Class A aggravated trafficking in heroin and operating a motor vehicle after suspension. Her bail was set at $35,000 cash.
