CHARLES TOWN – A Shepherdstown man was arrested late Tuesday night – allegedly in possession of more than 18 pounds of marijuana – as the result of a joint investigation between local and federal law enforcement agencies, according to Jefferson County Sheriff Robert “Bobby” Shirley.

Jonah Blackwell Tremba, 34, was arraigned Wednesday in Jefferson County Magistrate Court on one felony count each of possession with intent to deliver and manufacture marijuana and conspiracy to distribute marijuana, according to court records.

The Jefferson County Sheriff’s Department, the federal Drug Enforcement Administration and the Shepherdstown and Ranson police departments participated in the investigation and arrest, according to Shirley.

“(The investigation) was based upon information we had received a while back and we looked into it. This is possible because of … the working relationship with multiple jurisdictions,” Shirley said. “We’re glad to take this kind of drug and drug activity off the streets.”

Officers executed a federal search warrant Tuesday at 1799 Bloomery Road, a residence Tremba was renting, according to the criminal complaint.

According to Shirley, officers found between 18 and 20 pounds of marijuana, marijuana plants, more than 10 strains – or types -of marijuana and more than $31,000 in the residence. The street value of the seized marijuana was more than $20,000.

Officers seized boxes of baggies and two scales, and they found the different strains in mason jars along with ziploc bags containing marijuana. Officers also found a tent with a lighting and ventilation system at the residence and seven pots with marijuana growing in them inside the tent, according to the criminal complaint.

The criminal complaint said that Tremba contended he was “solely responsible” for the marijuana found in the residence.

Tremba was arrested, processed and transported to Eastern Regional Jail.

He was arraigned Wednesday and later released on a $100,000 bond, records show.

Detective T. Harrison with the JCSD was the arresting officer, and the investigation is ongoing.
