GREENVILLE, N.C. (WNCT) — A 27-year-old Winterville man the U.S. Attorney’s Office said was using women as drug mules to bring heroin to North Carolina was sentenced in federal court to 25 years in prison Tuesday.

Maurice Moore Jr. was named in a three-count indictment filed in 2016 and pleaded guilty to conspiracy to distribute and possess with intent to distribute 100 grams or more of heroin and possession of ammunition by a felon on December 5. After his prison term is up, Moore will have to spend an additional five years on supervised release.

The Naval Criminal Investigative Service began their investigation into Moore in 2013 after they said they received information identifying Moore as dealing heroin and promoting prostitution at U.S. Marine Corps bases near Jacksonville.

The U.S. Attorney’s Office said the investigation revealed Moore purchased heroin from an individual in New York and used women as drug mules to bring the drugs back to North Carolina.

Multiple witness statements revealed Moore was frequently seen with firearms, and the prosecutor said he was in possession of both assault rifles and heroin in the hotel rooms and other locations he used to stash his drugs.

Moore also got the prostitutes he was pimping addicted to heroin to facilitate the distribution of the drug, according to the investigation.

This case was investigated by the NCIS, the Craven County Sheriff’s Office, the Pitt County Sheriff’s Office, the Pamlico County Sheriff’s Office, the Havelock Police Department, and the Jacksonville Police Department.

Assistant U.S. Attorney Scott Lemmon prosecuted the case on behalf of the government.
